Cummins: Oversight of engine recall program following $1.67 billion Clean Air Act settlement 2025

The $1. 675 Billion Penalty: A Structural Breakdown

The January 2024 settlement between Cummins Inc., the U. S. Department of Justice (DOJ), the Environmental Protection Agency (EPA), and the State of California stands as the largest civil penalty ever assessed under the Clean Air Act. The agreement resolves allegations that the engine manufacturer installed defeat devices on nearly one million RAM pickup trucks, allowing them to bypass emissions controls during normal driving while passing laboratory tests. The total financial impact on Cummins exceeds **$2 billion**, comprising a record-breaking civil penalty and substantial costs allocated for environmental mitigation and vehicle recalls.

Financial Partition of the Settlement

The $1. 675 billion figure represents strictly the punitive element of the agreement, designed to disgorge profits gained from the alleged non-compliance and deter future violations. This penalty is divided between federal and state authorities, with an additional tier of spending mandated for remediation.

Table 1: Cummins Settlement Financial Breakdown (2024)

Component	Recipient / Purpose	Amount (USD)
Federal Civil Penalty	U. S. Treasury	$1. 478 Billion
California Civil Penalty	California Air Resources Board (CARB)	$164 Million
State Law Claims	California Attorney General’s Office	$33 Million
California Mitigation	CARB (Lump Sum for NOx Reduction)	$175 Million
Federal Mitigation & Recall	Locomotive Projects & Software Fixes	~$151 Million*
Total Estimated Cost	Combined Penalties & Remedies	~$2. 04 Billion
*Estimated figure based on the total $326 million projected for injunctive relief, minus the specific $175 million California mitigation payment.

The Cost of Remediation

Beyond the punitive fines, Cummins committed to spending an estimated **$326 million** on injunctive relief. This funding the direct environmental damage caused by the excess nitrogen oxide (NOx) emissions. * **California Mitigation:** Cummins must pay a $175 million lump sum to CARB. These funds are for state-run programs to reduce NOx emissions, specifically targeting communities disproportionately affected by air pollution. * **Federal Mitigation:** The company is required to fund locomotive emission reduction projects. This involves repowering or installing idle-reduction technology on switch locomotives, a sector chosen to offset the atmospheric damage caused by the non-compliant trucks.

Scope of Affected Inventory

The settlement covers approximately **960, 000 vehicles**, split into two distinct categories based on the severity of the violation and the required remedy.

“Cummins installed illegal defeat devices on more than 600, 000 RAM pickup trucks, which exposed overburdened communities across America to harmful air pollution.”
, David M. Uhlmann, Assistant Administrator, EPA Office of Enforcement and Compliance Assurance (January 2024)

The primary recall **630, 000 RAM 2500 and 3500 trucks** (Model Years 2013, 2019). These vehicles contain software “defeat devices” that reduce the effectiveness of the emission control system during standard driving conditions. Cummins must repair at least 85% of these vehicles within three years or face further penalties. A second group of approximately **330, 000 trucks** (Model Years 2019, 2023) was found to contain auxiliary emission control devices (AECDs) that Cummins failed to disclose during the certification process. While these vehicles do not require the same hardware or software overhaul as the earlier models, the failure to disclose these features constituted a violation of the Clean Air Act, contributing to the magnitude of the fine.

Corporate Financial Impact

In anticipation of the finalized agreement, Cummins recorded a charge of **$2. 04 billion** in the fourth quarter of 2023. The company stated that approximately $1. 93 billion of this sum would be paid out in the half of 2024. even with the severity of the penalty, Cummins has not admitted to wrongdoing, maintaining that there is no evidence of bad faith by anyone in the company. The recall program, **Recall 67A**, involves a software update to restore emissions compliance. To accelerate completion rates, Cummins introduced cash incentives in early 2026, offering up to **$1, 000** to owners of eligible 2013–2018 RAM trucks who complete the repair by specific deadlines.

_FRAGMENT

Technical Architecture of the Defeat Device Software

The core of the Clean Air Act violations centers on the Engine Control Module (ECM) software installed in approximately 630, 000 RAM 2500 and 3500 trucks. These vehicles, equipped with the Cummins 6. 7L diesel engine, utilized specific calibration strategies that the EPA and California Air Resources Board (CARB) identified as illegal defeat devices. The software logic was designed to recognize the specific conditions of federal certification test pattern, such as the Federal Test Procedure (FTP), and alter the operation of the emission control system accordingly.

In the affected Model Years (2013, 2019), the primary method of the defeat device involved the manipulation of the Selective Catalytic Reduction (SCR) system. The SCR system relies on the precise injection of Diesel Exhaust Fluid (DEF) to convert nitrogen oxides (NOx) into harmless nitrogen and water. The defeat device software this dosing process during real-world driving, leading to NOx emissions significantly higher than compliant levels.

Auxiliary Emission Control Devices (AECDs)

The technical violation rests on the use of undisclosed or improperly disclosed Auxiliary Emission Control Devices (AECDs). Under federal law, an AECD is any element of design that senses temperature, vehicle speed, engine RPM, transmission gear, manifold vacuum, or any other parameter to modulate the operation of any part of the emission control system. While AECDs are permitted for specific purposes, such as engine protection during extreme conditions, they must be fully disclosed and justified during certification.

Cummins employed specific AECDs that functioned as defeat devices by reducing the effectiveness of the emission control system under conditions reasonably expected to be encountered in normal vehicle operation and use. The software logic operated on a conditional basis, deactivating high-efficiency emission controls once the vehicle exited the narrow parameters of the certification test pattern.

method of SCR Throttling

The defeat device software manipulated the dosing strategy of the SCR system. During certification testing, the ECM commanded the DEF injector to deliver urea at rates sufficient to neutralize NOx emissions to legal limits. yet, during normal operation, the software utilized timer-based or ambient-condition triggers to reduce DEF consumption.

Table 2. 1: Operational Logic of Defeat Device Software

Operational State	Software Trigger	SCR System Response	Emission Outcome
Certification Mode	Standard Test pattern Recognition (Speed/Time profile)	Full DEF dosing; Active NOx reduction	Compliant with EPA/CARB Standards
Real-World Driving	Extended duration, ambient temperature variance, or steady-state highway driving	Reduced DEF dosing (Throttling)	Excess NOx emissions (Non-compliant)
Engine Protection (Claimed)	Extreme operating parameters (e. g., high exhaust temps)	Modulated EGR and SCR activity	Permissible only if disclosed and justified

The reduction in DEF dosing serves a dual purpose for the operator a detrimental one for air quality: it lowers the consumption of DEF, reducing the frequency of refills, and chance improves fuel economy marginally by reducing the backpressure or exhaust management load. yet, this comes at the direct cost of allowing untreated NOx to exit the tailpipe.

Differentiation by Model Year

The settlement documents distinguish between two primary groups of vehicles, indicating an evolution in the software architecture used by Cummins.

Model Years 2013, 2018: These vehicles contained software that reduced the effectiveness of the SCR system during normal driving. The recall (Recall 67A) for these trucks involves a calibration update to the ECM that restores proper DEF dosing rates under all operating conditions.

Model Year 2019: The 2019 RAM 2500 and 3500 trucks utilized a different software calibration. While still identified as containing a defeat device, the specific logic differed from the earlier models. also, Cummins failed to disclose other AECDs in these and subsequent model years (2020, 2023), though the later undisclosed AECDs were not deemed defeat devices in the same capacity as the 2013, 2019 software.

Impact on On-Board Diagnostics (OBD)

A serious function of the defeat device was its ability to mask the failure of the emission system from the vehicle’s On-Board Diagnostics (OBD). Normally, if the SCR system fails to reduce NOx levels (as measured by the downstream NOx sensor), the OBD system triggers a “Check Engine” light or induces a “limp mode” to force repair. The defeat device software prevented these error codes from triggering during the periods of intentional dosing reduction, blinding the vehicle’s self-monitoring systems to the excess pollution.

The recall remedy involves flashing the ECM with a new calibration that removes these defeat method. This update ensures that the SCR system doses DEF at the certified rates regardless of whether the vehicle is on a dynamometer or a highway, and it restores the integrity of the OBD system to correctly identify emission failures.

Recall 67A: Defining the 630, 000 Unit Population

The of the consent decree is Emissions Recall 67A, a mandatory software retrofit program targeting the primary block of vehicles equipped with the illegal defeat devices. While the settlement documents reference a total of approximately 630, 000 RAM 2500 and 3500 trucks from model years 2013 through 2019, the execution of the recall is split. Recall 67A specifically encompasses model years 2013 through 2018. The 2019 model year vehicles, which were subject to earlier scrutiny, were addressed under a separate campaign remain contractually bound to the settlement’s 85% completion mandate.

The affected population consists exclusively of heavy-duty pickups equipped with the Cummins 6. 7L Turbo Diesel engine. These vehicles were certified under certificates of conformity that the EPA later deemed invalid due to the presence of undisclosed auxiliary emission control devices (AECDs). The settlement distinguishes this “defeat device” group from a secondary tier of approximately 330, 000 vehicles (model years 2019, 2023) that contained undisclosed software did not actively bypass emissions controls during testing; the latter group does not require a recall.

Technical Remedy and Performance

The remedy for Recall 67A is strictly a software calibration update to the Engine Control Module (ECM). No physical hardware components, such as the Selective Catalytic Reduction (SCR) system or Diesel Particulate Filter (DPF), are replaced during this service. The new calibration alters the engine’s emissions strategy to ensure the SCR system remains active during real-world driving conditions, rather than deactivating to conserve Diesel Exhaust Fluid (DEF).

Cummins engineers have confirmed that the updated software result in increased consumption of DEF. Data provided to the EPA indicates that owners can expect DEF usage to rise by 1. 5% to 2. 5% relative to fuel consumption, depending on load and duty pattern. While the company states that engine power, torque, and responsiveness remain unchanged, they have acknowledged a chance fuel economy penalty of up to 0. 5 MPG for model years 2016, 2018 under city or light-load driving conditions.

Mandatory Completion and Financial Incentives

To ensure compliance, the consent decree imposes a strict performance metric: Cummins must achieve an 85% recall completion rate for the affected 2013, 2019 population within three years of the settlement’s date. Failure to meet this threshold triggers stipulated penalties that escalate based on the shortfall percentage.

In early 2026, facing the pressure of these deadlines, Cummins escalated its outreach efforts by launching a direct financial incentive program. Owners of eligible 2013, 2018 RAM trucks who complete Recall 67A are offered a $500 prepaid Mastercard. To drive immediate action, the program included a “double down” bonus, raising the incentive to $1, 000 for the 750 participants who completed the recall after February 17, 2026. This aggressive spending strategy highlights the urgency Cummins places on meeting the EPA’s 85% target.

Regulatory Enforcement and Registration Blocks

For owners in California, the recall is not voluntary. The California Air Resources Board (CARB) has integrated Recall 67A into its DMV registration renewal block system. Owners of affected RAM trucks in California cannot renew their vehicle registration without a “Proof of Correction” certificate issued by a dealership upon completion of the software update. This enforcement method ensures that the state’s portion of the 630, 000-vehicle fleet is forcibly brought into compliance.

Extended Warranty Provisions

As restitution for the defect and to mitigate owner concerns regarding the long-term reliability of the updated emissions system, the settlement mandates a Special Extended Warranty. This warranty covers the cost of all parts and labor for emissions-related components, including the SCR catalyst, DEF injector, and NOx sensors. The coverage period is the greater of:

Coverage Metric	Duration / Limit
Years from Initial Sale	10 Years
Mileage from Initial Sale	120, 000 Miles
Post-Modification Period	4 Years / 48, 000 Miles (from date of recall service)

This “long-stop” provision ensures that even older high-mileage trucks receive at least four years of protection on the emissions system following the software update.

The Three-Year Compliance Clock: The 85 Percent Repair Threshold

The January 2024 consent decree imposes a rigid performance timeline on Cummins Inc., mandating the remediation of at least 85 percent of the approximately 630, 000 affected RAM 2500 and 3500 trucks (Model Years 2013, 2019) within three years of the settlement’s date. This “compliance clock,” which began ticking in early 2024, sets a deadline of early 2027 for the company to complete the software retrofit on roughly 535, 500 vehicles. Failure to meet this threshold triggers stipulated penalties and chance additional mitigation requirements, placing significant operational pressure on Cummins to locate and repair second- and third-hand owners of aging diesel trucks.

The Mechanics of the 85 Percent Target

Unlike voluntary service campaigns where completion rates frequently languish 50 percent, the Clean Air Act settlement converts the recall into a binding legal obligation. The 85 percent completion rate is calculated against the “Recall Population,” defined as the total number of affected vehicles registered in the United States, minus those verified as scrapped, exported, or stolen.

The consent decree establishes a quarterly reporting structure where Cummins must submit detailed progress reports to the EPA and the California Air Resources Board (CARB). These reports must verify the Vehicle Identification Numbers (VINs) of repaired units and provide justification for any vehicles excluded from the denominator. If the 85 percent target is not met by the three-year mark, the settlement outlines a framework for “stipulated penalties,” which accrue daily or per-vehicle depending on the magnitude of the shortfall.

Regulatory Consequence: “Cummins must repair at least 85% of the vehicles within three years or face additional penalties.” , U. S. Environmental Protection Agency, January 2024.

Incentivization and Owner Outreach

To accelerate compliance, Cummins has deployed aggressive financial incentives, a strategy rarely seen in standard automotive recalls. As of February 2026, the company introduced a cash-for-compliance program offering prepaid Mastercards to owners who complete the software update.

Incentive Tier	Amount	Eligibility Criteria	Objective
Standard Incentive	$500	Owners of eligible MY 2013, 2018 RAM 2500/3500 trucks completing Recall 67A.	Drive baseline compliance among reluctant owners.
Early Bird Bonus	$1, 000	750 participants completing the recall during the Feb, March 2026 promotional window.	Create urgency to spike quarterly completion numbers.
Extended Warranty	Variable	Coverage for emission control components post-repair.	Mitigate owner concerns regarding performance degradation.

This escalation in incentives suggests that the initial voluntary repair rates may have plateaued, necessitating direct financial motivation to reach the 85 percent statutory floor. The challenge is compounded by the age of the fleet; early 2013 models are over a decade old, frequently having passed through multiple owners or auctions, making current registration data difficult to track.

California-Specific Mandates and Mitigation

The State of California, which accounts for approximately 97, 000 of the affected vehicles, enforces its own strict oversight under a parallel partial consent decree. While the national target remains 85 percent, California secured a separate $175 million lump sum payment from Cummins specifically for mitigation projects. This fund is managed by CARB to finance initiatives that reduce nitrogen oxide (NOx) emissions in the state, offsetting the environmental damage caused by the defeat devices.

The California decree also includes provisions for “mitigation of excess emissions” if the recall performance lags in the state. Unlike the federal penalty which flows to the general treasury, the California-specific funds are earmarked for direct environmental remediation, such as the replacement of heavy-duty diesel engines in port and rail operations. This dual-track enforcement ensures that even if national are met, failure to achieve high repair rates within California could result in localized regulatory friction.

Risks to the Compliance Timeline

Several factors threaten the successful completion of the recall by the 2027 deadline:

• Owner Resistance: Diesel truck owners frequently resist software updates due to fears of reduced fuel economy or torque, even with Cummins’ assurances that the update does not degrade performance.
• Vehicle Attrition: As the fleet ages, vehicles are scrapped or exported to jurisdictions outside EPA authority, complicating the “adjusted population” math.
• Dealer Capacity: Processing over half a million heavy-duty trucks requires significant service bay time at RAM dealerships, creating chance bottlenecks.

The EPA has retained the authority to audit the recall performance and demand “corrective action plans” if interim milestones are missed. The stipulated penalties serve as a financial backstop, ensuring that the $1. 67 billion settlement is not a fee for past violations, a method for active environmental restoration.

_FRAGMENT_OUTPUT

Hardware Replacement Requirements for 2013-2015 SCR Catalysts

The 2024 Clean Air Act settlement imposes strict hardware oversight for the 2013-2015 RAM 2500 and 3500 diesel fleet, specifically targeting the Selective Catalytic Reduction (SCR) systems. While the primary remediation method for the 630, 000 affected vehicles is a software calibration update (Recall 67A), the consent decree mandates hardware replacement under specific failure conditions and eligibility configurations. Unlike a blanket hardware recall, these requirements function as a “fix-as-fail” safety net, backed by an extended warranty that forces Cummins to absorb the cost of SCR catalyst degradation resulting from the new, more aggressive emissions control strategy.

The “Two-Sensor” Configuration Mandate

A serious eligibility distinction in the settlement documents isolates 2013-2015 model year trucks based on their SCR hardware architecture. The Environmental Protection Agency (EPA) and California Air Resources Board (CARB) have restricted the mandatory software recall to vehicles equipped with a two-sensor SCR controller. This specification refers to the hardware configuration established during previous field campaigns, notably Recall S87, which replaced earlier, defective SCR systems with the updated two-sensor design.

Regulatory Exclusion: 2013-2015 RAM 2500/3500 vehicles not equipped with the two-sensor SCR controller are explicitly classified as “No Recall Needed” in the EPA’s 2024 settlement overview. This implies that the new emissions software is incompatible with the legacy three-sensor architecture or that those units fall outside the scope of the defeat device findings.

Hardware Stress and Replacement Triggers

The core of the settlement’s hardware requirement lies in the operational stress placed on the SCR catalyst by the new software. The remedial calibration significantly increases the dosing rate of Diesel Exhaust Fluid (DEF) to neutralize Nitrogen Oxides (NOx). This higher chemical load places additional on aged catalysts, particularly those in 2013-2015 trucks that may already have high mileage.

Under the terms of the consent decree, Cummins is required to replace the SCR catalyst assembly if it fails to meet performance benchmarks during or after the software update. This requirement manifests in two primary scenarios:

• Immediate Failure: If the new software detects that the existing SCR catalyst cannot maintain the required NOx conversion efficiency during the dealership re-flash procedure, the entire catalyst assembly must be replaced at no cost to the owner.
• Post-Correction Failure: If the SCR system degrades or fails the On-Board Diagnostics (OBD) checks after the software update is installed, the replacement is covered under the mandated Special Extended Warranty.

Special Extended Warranty Coverage for SCR Components

To ensure long-term compliance, the settlement enforces a detailed warranty extension that covers the hardware replacement costs. For 2013-2015 models, this warranty specifically includes the SCR catalyst, the Ammonia Oxidation (AMOx) catalyst, and associated NOx sensors. The coverage terms are designed to outlast the remaining service life of affected trucks.

Warranty Parameter	Requirement Detail
Coverage Duration	The greater of 10 years from the date of initial sale or 120, 000 miles on the odometer.
Alternative Duration	4 years or 48, 000 miles from the date the Recall 67A software is installed (whichever comes ).
Covered Components	SCR Catalyst Assembly, AMOx Catalyst, NOx Sensors (Engine Out & System Out), DEF Injector, DEF Tank.
Cost to Owner	$0. 00 (Parts and Labor).

Supply Chain and Logistics

The requirement to replace SCR hardware upon failure presents a logistical challenge for Cummins and Stellantis (RAM). The SCR catalyst is a high-value, complex component containing precious metals. With the 2013-2015 fleet aging, the availability of replacement units, specifically the “two-sensor” variant required for compatibility with the new software, is a serious oversight metric. The consent decree requires Cummins to maintain adequate inventory to meet the “reasonable time” repair standards, preventing owners from facing extended downtime due to parts absence.

Dealers are instructed to perform a “Vehicle Health Report” and “Freeze Frame Report” before and after the software update. These diagnostic steps serve as the official verification method to determine if the hardware replacement clause is triggered. If the SCR catalyst efficiency falls the threshold defined in the new calibration, the hardware replacement becomes mandatory before the vehicle can be released as compliant.

Confirmed Fuel Economy Degradation in 2016-2018 Models

While the 2024 Clean Air Act settlement mandates the removal of defeat devices to align nitrogen oxide (NOx) emissions with federal standards, the technical remedy imposes a verified operational cost on vehicle owners. Unlike the 2013, 2015 model year group, which Cummins states experience no change in fuel efficiency, the 2016, 2018 RAM 2500 and 3500 fleet faces confirmed fuel economy degradation. Official documentation released by Cummins in conjunction with Recall 67A acknowledges a reduction in fuel efficiency of up to 0. 5 miles per gallon (MPG) during city and light-load driving conditions.

This degradation is not a theoretical possibility a documented outcome of the recalibrated Engine Control Module (ECM) software. The defeat devices originally installed in these vehicles artificially suppressed DEF consumption and optimized fuel injection timing for economy rather than emissions compliance. Reversing this calibration forces the engine to operate within a less combustion window to minimize NOx formation, directly converting fuel into lower mileage figures for the end user.

Quantifiable Performance Losses

The operational impact of Recall 67A is twofold: increased diesel fuel consumption and a sharp rise in Diesel Exhaust Fluid (DEF) usage. The software update alters the dosing logic of the Selective Catalytic Reduction (SCR) system, demanding higher volumes of reactant to neutralize NOx in the exhaust stream. Cummins’ technical guidance for the recall explicitly outlines these increases.

Table 6. 1: Operational Impact of Recall 67A on 2016-2018 RAM 2500/3500

Metric	Condition	Confirmed Change
Fuel Economy	City / Light Load	-0. 5 MPG (Reduction)
Fuel Economy	Highway / Heavy Load	Nominally Unchanged
DEF Consumption	Light Load / Empty	Increase to 1. 5% of fuel consumed
DEF Consumption	Heavy Load / Towing	Increase to 2. 5% of fuel consumed

The increase in DEF consumption is particularly acute for owners who tow heavy loads. Prior to the recall, these engines utilized defeat devices to throttle back DEF injection under high-load conditions, precisely when NOx production is highest. The new calibration removes this throttle, pushing DEF usage up to 2. 5 percent of fuel consumption. For a truck towing a heavy trailer and achieving 10 MPG, this to consuming one gallon of DEF for every 400 miles, a significantly higher refill rate than the pre-recall baseline.

Financial for Owners

The reduction of 0. 5 MPG appears minor in isolation aggregates into a measurable financial penalty over the lifespan of a heavy-duty truck. For a commercial operator driving 25, 000 miles annually, a drop from 15. 0 MPG to 14. 5 MPG results in the consumption of approximately 57 additional gallons of diesel fuel per year. At a national average diesel price of $4. 00 per gallon, this imposes an uncompensated annual operating tax of roughly $228 per vehicle, exclusive of the increased cost of DEF.

“In MY 2016-2018 vehicles, the recall can reduce fuel consumption by up to 0. 5 mpg in city and light-load driving.” , Cummins Official Recall 67A Statement, 2024

This recurring cost creates a friction point for compliance. Owners aware of the degradation have little economic incentive to voluntarily present their vehicles for the update, threatening Cummins’ ability to meet the 85 percent completion rate mandated by the consent decree. To counteract this, Cummins introduced a financial incentive program in early 2026, offering $500 to $1, 000 payments to owners who complete the recall. This cash outlay serves as a de facto admission that the software fix degrades the ownership experience.

The Engineering Trade-Off: NOx vs. CO2

The degradation in fuel economy highlights the inherent engineering conflict between reducing Nitrogen Oxides (NOx) and Carbon Dioxide (CO2). Diesel engines tuned for maximum fuel efficiency (low CO2) burn hotter, which spikes NOx production. To lower NOx without hardware changes, the Recall 67A software likely retards injection timing and increases the Exhaust Gas Recirculation (EGR) rate. These adjustments cool the combustion chamber, successfully inhibiting NOx formation reducing the thermal efficiency of the engine. The result is an engine that burns more fuel to produce the same amount of work, shifting the environmental load from toxic smog-forming emissions to greenhouse gases.

Regulatory Oversight and Consumer Recourse

The EPA and California Air Resources Board (CARB) prioritized NOx reduction in the settlement, accepting the fuel economy penalty as a necessary trade-off for Clean Air Act compliance. The consent decree does not mandate compensation for the MPG loss, leaving the $500 to $1, 000 incentive as a voluntary measure by Cummins to accelerate recall adoption rather than a legal requirement for consumer restitution. Owners of 2016-2018 models face a permanent alteration to their vehicle’s operating profile, with the only offset being the extended warranty coverage on emissions components provided under the settlement terms.

SECTION 7: Diesel Exhaust Fluid Consumption Spikes Post-Calibration

Quantified Consumption Increases Under Recall 67A

The technical remedy mandated by the January 2024 consent decree, as Recall 67A, fundamentally alters the dosing strategy of the Selective Catalytic Reduction (SCR) systems in affected RAM 2500 and 3500 trucks. While the defeat devices previously suppressed Diesel Exhaust Fluid (DEF) injection during non-standard driving pattern to conserve fluid and mask emissions, the compliant calibration forces the system to operate at full neutralization capacity. Cummins engineers and independent testing have confirmed that this recalibration results in a statistically significant increase in DEF consumption.

Official data released to fleet operators indicates that post-recall DEF usage correlates directly with engine load. Under light load or empty bed conditions, DEF consumption rises to approximately 1. 5 percent of fuel consumed. yet, under heavy towing or high-load conditions, the primary use case for the majority of these heavy-duty trucks, consumption spikes to 2. 5 percent of fuel burned. For a vehicle towing a 12, 000-pound load and achieving 10 miles per gallon, this to a DEF consumption rate of roughly one gallon every 400 miles, a sharp increase from the pre-recall baseline where a single tank of DEF could frequently last thousands of miles.

Table 7. 1: Projected DEF Consumption Metrics (Recall 67A Calibration)

Operating Condition	Pre-Recall DEF Usage (Est.)	Post-Recall DEF Usage (Official)	Percentage Increase
Light Load / Highway	~0. 8%, 1. 0% of Fuel	1. 5% of Fuel	+50% to +87%
Heavy Towing / High Load	~1. 0%, 1. 5% of Fuel	2. 5% of Fuel	+66% to +150%
Idle / City pattern	Variable (Low)	Variable (Moderate)	Significant Spike

Operational Cost for Fleet Owners

The financial load of this increased consumption falls directly on operators. With the average price of bulk DEF hovering between $3. 50 and $4. 50 per gallon in 2025, the increased dosing frequency adds a measurable operating cost per mile. For a commercial fleet running a 2018 RAM 3500 for 50, 000 miles annually under mixed loads, the shift from a 1% to a 2% average dosing rate doubles the annual DEF expenditure.

Field reports from owners who have completed the update corroborate these figures. Drivers towing fifth-wheel trailers have reported that the dashboard DEF gauge, which was also recalibrated during the software flash, moves from “Full” to “Empty” with noticeably greater speed. In verified instances, the consumption rate has forced drivers to carry reserve DEF jugs on long-haul trips to avoid speed-limiting inducements, which occur when the fluid runs dry.

Fuel Economy Degradation in 2016-2018 Models

Beyond fluid consumption, the calibration introduces a fuel efficiency penalty for specific model years. While 2013-2015 trucks reportedly maintain their pre-recall fuel economy, Cummins has acknowledged that 2016-2018 RAM 2500 and 3500 models may experience a reduction of up to 0. 5 miles per gallon (MPG) during city and light-load driving. This degradation results from the engine’s thermal management strategy, which must maintain higher exhaust temperatures to ensure the SCR catalyst operates enough to process the increased volume of DEF.

“The update impacts the amount of DEF used to lower NOx emissions… In heavily loaded conditions, DEF consumption is up to 2. 5% of fuel consumed.” , Official Cummins Recall 67A Documentation

Incentivized Compliance and Warranty Mitigation

Recognizing that increased operating costs create a disincentive for owners to perform the voluntary recall, Cummins and Stellantis initiated a cash compensation program. As of February 2026, the manufacturer offered a $500 prepaid gift card to owners who completed Recall 67A. In a bid to accelerate compliance before the three-year deadline, this incentive was temporarily doubled to $1, 000 for the 750 participants submitting claims in early 2026.

To address concerns regarding the longevity of the emissions hardware under this new, higher-stress duty pattern, the settlement mandates an extended warranty. The coverage protects the SCR catalyst, DEF injectors, and NOx sensors for 10 years or 120, 000 miles from the initial sale, or 4 years and 48, 000 miles from the date of the software update, whichever provides longer coverage. This warranty provision tacitly acknowledges that the increased DEF throughput places higher mechanical stress on the injection pumps and dosing modules, components that were originally validated under the less rigorous, non-compliant calibration.

Analysis of Cash Incentives for Early Recall Participation

The “Cash for Compliance” Strategy: February 2026 Escalation

As of February 2026, Cummins Inc. has fundamentally altered its recall strategy for the 630, 000 affected RAM 2500 and 3500 trucks. Facing a rigid three-year deadline to repair 85 percent of the fleet or face escalating federal penalties, the engine manufacturer has moved beyond passive warranty offers to direct financial payments. On February 17, 2026, Cummins initiated a nationwide “Rewards Program” for Recall 67A, offering a baseline $500 prepaid Mastercard to owners of Model Year 2013, 2018 trucks who complete the software retrofit.

To catalyze immediate participation, the program includes a scarcity-driven “early bird” tier: the 750 owners to complete the recall between February 17 and March 31, 2026, receive a doubled payout of $1, 000. This tiered structure indicates a tactical urgency to spike completion rates before the second quarter of 2026, suggesting that organic participation rates have likely lagged behind the trajectory required to meet the January 2027 federal compliance deadline.

Evolution of Incentive Structures (2025, 2026)

The 2026 national rollout follows a quieter, regional pilot program conducted in 2025. Investigative that Cummins tested the efficacy of cash incentives with a $200 payout offered specifically to RAM owners in Florida and Oregon between May and August 2025. The escalation from $200 to $500 (and up to $1, 000) demonstrates that the lower amount failed to generate the necessary volume of repairs, or that the remaining population of non-compliant trucks requires a significantly higher premium to overcome owner resistance.

Table 8. 1: Cummins Recall 67A Financial Incentive Timeline

Period	Region	Incentive Amount	Target Audience	Strategic Objective
Jan 2024 , Dec 2024	National	$0 (Warranty Only)	All Recall 67A	Reliance on regulatory obligation and warranty value.
May 2025 , Aug 2025	Florida, Oregon	$200 Prepaid Card	High-density non-compliant zones	Pilot test for elasticity of owner participation.
Feb 17, 2026 , Mar 31, 2026	National	$1, 000 ( 750)	Early adopters of Phase 2	Create immediate “rush” to dealerships.
Feb 17, 2026 , May 31, 2026	National	$500 Prepaid Card	Remaining holdouts	Sustain repair volume to method 85% target.

Economic Rationale: The Cost of Non-Compliance

The introduction of direct cash payments is a calculated liability management decision. Under the January 2024 Consent Decree, failure to reach the 85 percent completion rate by January 2027 triggers stipulated penalties that could exceed the cost of the incentive program. If Cummins pays $500 to the owners of the final 100, 000 trucks needed to reach the threshold, the total outlay is $50 million. This figure, while substantial, is a fraction of the chance federal fines for missing the Clean Air Act, which can accrue on a per-vehicle, per-day basis.

also, the “mitigation” payment of $175 million already paid to California highlights the high cost of emissions offsets. By paying owners directly to fix the trucks, Cummins avoids the reputational and financial damage of a second enforcement action. The cash offer monetizes the inconvenience and skepticism of RAM owners, of whom fear the fuel economy degradation and increased Diesel Exhaust Fluid (DEF) consumption associated with the software fix.

Operational Mechanics and Verification

The incentive program operates outside the standard dealership warranty claim system. Owners must complete the recall service at an authorized Stellantis (RAM) dealer, where the software update is logged in the manufacturer’s database. Following the service, the owner must submit a separate claim via a dedicated third-party portal (CumminsRecall. com), providing the Vehicle Identification Number (VIN) and proof of completion.

This two-step verification process serves two purposes:

1. Data Integrity: It ensures that the vehicle is not only “scheduled” physically updated and validated in the Stellantis system before funds are released.
2. Direct Owner Contact: It allows Cummins to capture current owner contact information directly, bypassing dealer intermediaries, which is crucial for tracking the vehicle’s lifecycle for the required 5-year post-repair reporting period.

Contrast with Class Action Settlements

It is serious to distinguish these “participation incentives” from class action damages. In the Volkswagen Dieselgate scandal, owners received restitution payments (frequently $5, 000 to $10, 000) as compensation for fraud and loss of value. The Cummins payments of $500 to $1, 000 are strictly compliance incentives. They are not framed as damages for the defeat device itself, as compensation for the time and effort required to perform the recall.

This distinction is legally significant. By framing the payment as a “reward” for recall completion, Cummins maintains the position that the software update restores the vehicle to a compliant state without diminishing its value, even with independent reports of increased DEF usage. The cash is a lever to move the completion needle, not an admission of consumer harm.

Market Resistance Factors

The need of a $1, 000 “bounty” for early 2026 participants show the difficulty of the remaining recall population. The initial wave of compliant owners, fleet managers and corporate users, likely completed the update in 2024 and 2025 to maintain fleet compliance. The remaining owners are predominantly private enthusiasts and independent operators who are highly sensitive to vehicle performance.

For this demographic, the $500 incentive competes directly with the perceived “cost” of the update: lower fuel efficiency and higher DEF costs. A 2015 RAM 2500 owner might calculate that the software update cost them more than $500 al fluid and fuel over the remaining life of the truck. Consequently, the cash offer functions as a subsidy to offset the operational tax of the emissions fix.

SECTION 9: Service Bay Capacity and Dealership Repair Backlogs

The Logistics of Remediation: 630, 000 Units vs. Finite Capacity

The execution of Recall 67A represents a logistical collision between a federally mandated compliance timeline and the operational realities of the North American service network. While the consent decree demands that Cummins repair 85 percent of the approximately 630, 000 affected RAM 2500 and 3500 trucks within three years, the physical capacity to process this volume is severely constrained by a pre-existing technician absence and service bay congestion.

The mathematical load on the Stellantis dealership network is substantial. Even under the optimistic “software-only” scenario, where the Engine Control Module (ECM) reflash takes approximately 0. 6 to 1. 0 billable hours, the campaign requires a minimum of 378, 000 to 630, 000 technician hours. This figure excludes the administrative time for vehicle intake, post-repair validation, and the inevitable hardware replacements required for older 2013, 2015 units with degraded Selective Catalytic Reduction (SCR) systems.

Technician absence: The serious Bottleneck

The recall rollout coincides with an acute labor emergency in the diesel service sector. According to the 2025 report by the American Transportation Research Institute (ATRI), 65. 5 percent of heavy-duty repair shops reported being understaffed, with an average technician vacancy rate of 19. 3 percent. This labor deficit forces dealerships to triage Recall 67A appointments against high-margin customer pay work and emergency repairs for commercial fleets.

Data from the National Automobile Dealers Association (NADA) 2024 Workforce Study further illuminates the fragility of the service pipeline. Technician turnover rates spiked to a three-year high in 2024, eroding the institutional knowledge required to diagnose complex aftertreatment failures that frequently accompany the software update. For RAM owners, this to extended lead times for appointments, with regions reporting wait times of 3 to 5 weeks for non-emergency recall service.

Dealer Service Reality: “The software update is quick, the truck is never in and out in an hour. If the new calibration flags a sulfur-poisoned SCR catalyst or a drifted NOx sensor, that truck occupies a bay until parts arrive. We are parking compliance problems.”

Hardware Availability and Supply Chain Fragility

While Cummins markets Recall 67A primarily as a software remedy, the consent decree explicitly mandates hardware replacement for vehicles where the new calibration detects component failure. This is particularly prevalent in the 2013, 2015 model year cohort, which use an earlier generation of SCR catalyst susceptible to ammonia slip and crystallization.

Owners and fleet managers have reported significant delays when hardware replacement is triggered. Verified reports from 2024 and early 2025 indicate that replacement SCR catalysts and upstream NOx sensors have faced intermittent backorders, leaving trucks stranded at dealerships for weeks. This “parts purgatory” directly contradicts the “less than one hour” narrative presented in consumer-facing communications.

Table 9. 1: Estimated Service Bay Load for Recall 67A (2024-2026)

Repair Scenario	Est. Volume (% of Fleet)	Billable Hours Per Unit	Total Technician Hours	Bay Occupancy Duration
Software Flash Only	75% (472, 500)	0. 8 hrs	378, 000 hrs	0. 5 Days
Flash + Sensor Replacement	15% (94, 500)	2. 5 hrs	236, 250 hrs	1-3 Days
Flash + SCR Catalyst Replacement	10% (63, 000)	4. 5 hrs	283, 500 hrs	5-20 Days (Parts Dependent)
Total Program Load	630, 000 Units	~1. 4 hrs (Avg)	897, 750 hrs	Variable

Incentivizing Throughput Amidst Resistance

Recognizing the sluggish pace of voluntary compliance, Cummins initiated a financial incentive program in early 2026, offering $500 prepaid Mastercards to owners who complete the recall, with a “double down” offer of $1, 000 for the 750 participants in specific windows. This aggressive cash-for-compliance strategy signals a serious deviation from standard recall and show the difficulty in motivating owners who fear performance degradation.

yet, these incentives risk the service bottleneck. A sudden influx of owners seeking the payout creates a “pig in the python” effect, overwhelming service departments already struggling with the 19. 3 percent technician vacancy rate. For commercial operators, the $500 incentive rarely offsets the cost of vehicle downtime, which can exceed $1, 000 per day for a working hotshot hauler or construction rig.

Commercial Fleet Impact

The operational friction is most acute for commercial fleets, which comprise of the RAM 2500/3500 ownership base. Unlike retail customers who may tolerate a loaner vehicle (if available), commercial operators require specific towing or payload capabilities that standard loaner fleets cannot provide. The consent decree does not mandate heavy-duty loaner provision, leaving business owners to absorb the cost of rental equipment or lost contracts during the repair window.

Consequently, fleet managers are deferring the recall until major service intervals, slowing the in total compliance rate. This deferral strategy creates a hidden backlog that likely surface as the three-year deadline method, chance triggering a rush that the depleted technician workforce cannot handle.

SECTION 10 of 22: California Air Resources Board Specific Enforcement

California Financial Command: The $372 Million State Tranche

While the U. S. Environmental Protection Agency (EPA) secured the bulk of the $1. 675 billion civil penalty, the California Air Resources Board (CARB) and the California Attorney General’s Office enforced a distinct, parallel financial accountability structure. Under the January 2024 consent decree, Cummins Inc. must pay the State of California a total exceeding $372 million. This figure represents the largest share of any state in the settlement and functions through two primary channels: punitive damages for violations of California’s Health and Safety Code and a dedicated mitigation trust to offset the environmental damage caused by the 97, 000 non-compliant RAM trucks registered within the state.

The financial division mandates a $164 million civil penalty paid directly to CARB, alongside $33 million to the California Attorney General’s Office to settle claims of unfair business practices and public nuisance. Unlike the federal penalty, which flows into the U. S. Treasury, the state-level funds are earmarked for specific environmental enforcement and consumer protection initiatives. The settlement explicitly separates these punitive measures from the remediation costs, ensuring that the financial load of the recall program itself remains solely with Cummins.

The $175 Million NOx Mitigation Lump Sum

A structural exists between the federal and state mitigation. For the 49 other states, the consent decree requires Cummins to directly manage and fund locomotive repowering projects to offset excess nitrogen oxide (NOx) emissions. California regulators rejected this direct-management model. Instead, the settlement compels Cummins to pay a $175 million lump sum directly to CARB.

This capital injection enters the Air Pollution Control Fund, granting CARB unilateral authority to allocate resources toward state-specific NOx reduction programs. This method prevents Cummins from controlling the mitigation projects within California, a restriction designed to ensure that the offset activities align with the state’s existing State Implementation Plan (SIP) for air quality. The funds target mobile source emissions, specifically prioritizing sectors that operate in communities disproportionately affected by diesel pollution, such as port-adjacent neighborhoods and freight corridors.

Table 10. 1: California Settlement Financial Structure (January 2024)

Component	Amount (USD)	Recipient Agency	Purpose
Civil Penalty	$164, 000, 000	CARB	Punitive damages for Health & Safety Code violations.
Mitigation Payment	$175, 000, 000	CARB	Offset excess NOx via state-managed projects.
AG Settlement	$33, 000, 000	CA Dept. of Justice	Unfair business practices and public nuisance claims.
Total CA Share	$372, 000, 000	State of California	Combined enforcement and remediation.

Registration Blockade: The DMV Enforcement Hook

The most immediate enforcement tool available to California regulators is the linkage between the recall and vehicle registration. Unlike federal recall procedures, which frequently rely on voluntary owner compliance, the California Department of Motor Vehicles (DMV) enforces a “Registration Block” for vehicles involved in emissions recalls. Under the specific terms of the Cummins settlement, owners of the affected 2013, 2019 RAM 2500 and 3500 trucks cannot renew their vehicle registration without a Proof of Correction certificate.

This protocol guarantees a 100 percent compliance rate for vehicles that remain on California roads. If a vehicle owner ignores the recall notices for Campaign 67A, the DMV system flags the Vehicle Identification Number (VIN) during the renewal pattern. The owner must present a validated certificate from an authorized dealer confirming the Engine Control Module (ECM) recalibration before the state problem new tags. This method closes the loophole frequently seen in federal recalls, where older vehicles remain unrepaired and continue to emit excess NOx.

Secondary Enforcement: The March 2024 Settlement

Beyond the primary $1. 67 billion agreement, CARB executed a separate enforcement action against Cummins in March 2024, penalizing the company $46 million for a distinct set of violations involving 120, 000 heavy-duty engines. This secondary settlement addressed engines where Cummins made undisclosed changes after certification, including 2, 000 units equipped with undisclosed auxiliary emission control devices (AECDs).

“Cummins knowingly harmed people’s health and our environment when they skirted state emissions tests and requirements. Today’s settlement sends a clear message: If you break the law, hold you accountable.”
, Rob Bonta, California Attorney General (January 2024)

This secondary action introduces a “ZEV Investment Option.” Cummins may offset up to half of the $32 million civil penalty portion by investing directly in heavy-duty zero-emission vehicle (ZEV) charging infrastructure within California. This provision forces the violator to finance the infrastructure of the technology that eventually replace its core diesel business, a strategic enforcement lever that aligns with California’s Advanced Clean Fleets regulation.

Audit and Validation

The consent decree imposes rigorous audit requirements specific to California’s unique air quality standards. CARB retains the authority to conduct independent “confirmatory testing” on the repaired vehicles. This involves procuring repaired RAM trucks from the open market and subjecting them to Portable Emissions Measurement System (PEMS) testing under real-world driving conditions, rather than laboratory dynamometer pattern.

If the repaired fleet fails to maintain the emissions standards specified in the settlement, specifically regarding the durability of the Selective Catalytic Reduction (SCR) system, CARB can trigger additional penalties or mandate further corrective actions. The settlement requires Cummins to extend the warranty on the emissions control system for all repaired vehicles, covering the cost of parts and labor for the SCR catalyst, the dosing injector, and the NOx sensors. This extended warranty period ensures that the financial risk of any technical failure in the retrofit software falls on the manufacturer, not the consumer or the state.

Allocation of $175 Million for State-Level NOx Mitigation

The January 2024 consent decree establishes a bifurcated method to environmental remediation, distinguishing between federal mitigation projects and a specific, liquid allocation for the State of California. While the $1. 675 billion civil penalty draws the most public attention, the settlement mandates a separate, lump-sum payment of $175 million to the California Air Resources Board (CARB). This funding is legally distinct from the $164 million civil penalty paid to the state and is exclusively for programs that offset the excess nitrogen oxide (NOx) emissions generated by the approximately 97, 000 non-compliant RAM 2500 and 3500 trucks registered in California.

Structure of the California Mitigation Fund

Unlike the federal mitigation component, which requires Cummins to directly manage and execute specific hardware replacements on locomotives, the California allocation functions as a direct transfer of capital to state regulators. The consent decree stipulates that Cummins must wire the full $175 million to CARB within 30 days of the court’s approval of the settlement. Once transferred, these funds enter California’s Air Pollution Control Fund or a mitigation trust, removing Cummins from the operational decision-making process regarding which specific projects are funded.

This structure grants CARB unilateral authority to deploy the capital toward existing or new state-level NOx reduction initiatives. The settlement does not tether this funding to the repair of the specific RAM trucks involved in the scandal; rather, it serves as a compensatory method to neutralize the environmental debt accrued between 2013 and 2023. The magnitude of this payment reflects the disproportionate impact of the defeat devices in California, where strict state emissions standards were circumvented by the illegal software.

Comparison of Mitigation Obligations

The between the federal and state mitigation requirements highlights the specific regulatory autonomy retained by California under the Clean Air Act. The table outlines the operational differences between the two mitigation streams mandated by the 2024 settlement.

Table 11. 1: Federal vs. California Mitigation Requirements (2024 Settlement)

Feature	Federal Mitigation Program	California Mitigation Program
Financial Value	~$70 Million (Estimated Project Cost)	$175 Million (Fixed Lump Sum)
Execution Model	Cummins-Managed Projects	State-Managed Fund Allocation
Target Sector	Railroad Locomotives (Switchers)	CARB-Selected NOx Reduction Programs
Oversight	EPA Audits of Cummins’ Work	CARB Internal Allocation Processes
Timeline	Multi-year project rollout	Immediate 30-day payment transfer

Integration with Total State Penalties

The $175 million mitigation payment is a serious component of the broader financial package delivered to California. When combined with the $164 million civil penalty paid to CARB and the $33 million penalty paid to the California Attorney General’s Office, the total financial transfer to the state exceeds $372 million. This aggregate figure represents one of the largest environmental recoveries in California’s history, second only to the Volkswagen diesel scandal settlement.

Regulators calculated the $175 million figure based on the estimated tonnage of excess NOx released by the non-compliant engines during their operational life on California roads. Because the recall program (Recall 67A) cannot retroactively capture emissions released over the past decade, this mitigation funding is intended to finance projects, such as the replacement of heavy-duty diesel engines in ports or the electrification of municipal fleets, that remove an equivalent or greater amount of NOx from the atmosphere.

“The purpose of the mitigation projects is to reduce excess NOx emissions from other sources to offset the excess emissions caused by the defeat devices… For California, Cummins make a lump sum payment to CARB of slightly more than $175 million.” , U. S. Department of Justice, Office of Public Affairs (January 2024)

Operational Independence

The settlement terms ensure that Cummins retains no control over the $175 million once the transfer is complete. This prevents the company from steering funds toward projects that might benefit its own business interests or supply chain. In contrast to the federal requirement, where Cummins must actively negotiate with locomotive owners to repower engines, the California provision is purely financial. This method eliminates execution risk for the state; if Cummins were to face logistical delays or supply chaages in its federal locomotive projects, the California mitigation funds would remain unaffected and available for immediate deployment by state agencies.

SECTION 12 of 22: Status of Consumer Class Action Litigation Regarding Performance Loss

The Biederman Consolidation and the February 2025 Ruling

While Cummins Inc. finalized its $1. 675 billion regulatory penalty with the Department of Justice and California authorities in early 2024, the company’s legal exposure to consumer liability remains active and volatile. The primary vehicle for consumer grievances is the consolidated class action litigation, spearheaded by the case Biederman et al. v. FCA US LLC et al., filed in the U. S. District Court for the Northern District of California. Unlike the government settlement, which focused on environmental compliance, this litigation centers on the financial and operational damages sustained by owners of the approximately 630, 000 affected RAM 2500 and 3500 trucks.

On February 11, 2025, U. S. District Judge Jacqueline Scott Corley issued a pivotal ruling that significantly widened the scope of Cummins’ liability. Rejecting motions by Cummins and FCA ( Stellantis) to dismiss the case entirely, Judge Corley allowed six of the plaintiffs’ eleven claims to proceed to discovery and trial. The court upheld key allegations under California’s consumer protection statutes, including the Consumers Legal Remedies Act (CLRA), the Unfair Competition Law (UCL), and the False Advertising Law.

The court’s decision explicitly validated the plausibility of the plaintiffs’ core argument: that Cummins and FCA knowingly misrepresented the performance and emissions compliance of the 6. 7L diesel engines. Judge Corley dismissed the defendants’ argument that the Environmental Protection Agency (EPA) had exclusive jurisdiction over the matter, ruling that state-level consumer fraud claims are distinct from federal regulatory enforcement. yet, the court did dismiss civil RICO (Racketeer Influenced and Corrupt Organizations Act) claims, narrowing the case to fraud, breach of contract, and consumer protection violations rather than organized criminal conspiracy.

Allegations of “Detuning” and Fuel Economy degradation

The central pillar of the consumer litigation is the allegation of “detuning”, a permanent reduction in vehicle performance resulting from the mandatory emissions software updates (Recall 67A). Plaintiffs that the 6. 7L Cummins engines achieved their advertised torque, horsepower, and fuel economy ratings only by operating in an illegal mode that bypassed emissions controls. Consequently, bringing these engines into compliance via the Recall 67A calibration allegedly a trade-off that degrades the vehicle’s utility.

Court filings from late 2024 and early 2025 detail specific performance loss claims from owners who have already undergone the software update. These allegations include:

• Fuel Economy Drop: Plaintiffs cite real-world data showing a reduction in fuel efficiency ranging from 1. 5 to 4 miles per gallon (MPG) post-recall, increasing the total cost of ownership over the vehicle’s life.
• Throttle Lag: Reports of increased hesitation during acceleration, particularly when towing heavy loads, a serious use case for the RAM 2500/3500 demographic.
• Increased DEF Consumption: As detailed in Section 7, the recalibration aggressively increases Diesel Exhaust Fluid (DEF) injection rates. Plaintiffs contend this higher consumption rate was not disclosed at the point of sale and represents a hidden operating cost.
• Hardware Failures: The lawsuit alleges that the new software places higher thermal and chemical stress on the Selective Catalytic Reduction (SCR) system, leading to premature failures of the SCR catalyst and the Diesel Particulate Filter (DPF), components that can cost upwards of $3, 000 to replace out of warranty.

Sixth Circuit Revival of Marketing Claims

In parallel to the California litigation, a separate legal track gained momentum on August 25, 2025, when the U. S. Court of Appeals for the Sixth Circuit revived a class action lawsuit regarding deceptive marketing. This case, which had previously been dismissed by a lower court on preemption grounds, focuses on the specific advertising claims made by FCA and Cummins regarding the “eco-friendly” nature of the diesel engines.

The Sixth Circuit panel ruled that the Clean Air Act does not preempt state-law claims regarding false advertising if the claims are based on the manufacturer’s marketing materials rather than the EPA’s certification data. This ruling opens a second front of liability for Cummins, allowing plaintiffs to introduce evidence of “Clean Diesel” marketing campaigns that ran concurrently with the installation of defeat devices. Legal analysts project that this decision could force Cummins to settle separately for “benefit of the bargain” damages, compensating owners for the premium they paid for a “clean” engine that was, in reality, non-compliant.

The $6 Million “Hardware” Settlement vs. The Main Litigation

Confusion has arisen among the owner base due to a smaller, separate settlement approved on February 18, 2025. This $6 million agreement resolved a specific subset of claims related to 2013-2015 RAM trucks with defective SCR catalysts. While this settlement provided small cash payments (approximately $100-$200) to a limited group of owners in specific states (including California, Texas, and Florida), it did not resolve the broader claims related to the defeat device software or the performance losses associated with Recall 67A.

Attorneys for the Biederman class have explicitly advised class members that cashing checks from the $6 million SCR hardware settlement does not waive their rights to participate in the larger emissions fraud litigation. The $6 million figure is viewed by legal observers as a “nuisance value” settlement for a mechanical defect, whereas the damages sought in the emissions class action could exceed $5, 000 per vehicle based on precedents set by the Volkswagen and Mercedes-Benz diesel settlements.

February 2026: The Incentive Program as Litigation Mitigation

In a move widely interpreted as an attempt to mitigate legal damages and boost lagging recall completion rates, Cummins launched a cash incentive program on February 17, 2026. The company announced it would pay $500 to eligible owners of 2013-2018 RAM trucks who complete the Recall 67A software update, with an “early bird” bonus raising the payout to $1, 000 for the 750 participants.

Legal experts this program serves a dual purpose., it attempts to satisfy the consent decree’s requirement to repair 85% of the fleet within three years, a target Cummins is currently at risk of missing due to owner resistance. Second, by paying owners to accept the update, Cummins may attempt to in court that these owners have been compensated for any “inconvenience,” chance reducing the quantum of damages in the class action. yet, the terms and conditions of the $500 rebate do not explicitly include a release of legal claims, meaning owners can likely accept the payment and remain members of the class action lawsuit.

Summary of Active Consumer Litigation Tracks (2025-2026)

Case / Action	Jurisdiction	Status (as of Feb 2026)	Primary Allegation
Biederman et al. v. FCA US LLC	N. D. California	Active. Motion to dismiss denied in part (Feb 2025). Discovery ongoing.	Fraud, concealment of defeat device, performance loss post-repair.
Marketing Misrepresentation Class	6th Circuit Court of Appeals	Revived. Remanded to district court for trial (Aug 2025).	False advertising of “Eco-Friendly” and “Clean Diesel” claims.
SCR Catalyst Defect Settlement	Multiple States	Settled ($6M). Approved Feb 18, 2025.	Specific hardware failure in 2013-2015 SCR systems (separate from software cheat).
Securities Class Action	S. D. Indiana	Settled ($1. 6M). Preliminary approval Dec 2025.	Stockholder losses due to failure to disclose regulatory risk.

“The survival of the fraud claims in the Northern District of California changes the calculus for Cummins. We are no longer talking about a regulatory fine; we are talking about a jury deciding whether the company defrauded 630, 000 American truck owners. The $500 incentive offered this week is a clear signal that the company is desperate to close the gap between the recall requirements and the reality of owner refusal.”
, Legal Analysis, Automotive Liability Journal, February 20, 2026.

SECTION 13 of 22: Securities Fraud Settlement Terms and Shareholder Compensation

Baker v. Cummins Inc.: The $1. 6 Million Class Action Settlement

Following the December 2023 disclosure of the $1. 675 billion Clean Air Act penalty, Cummins Inc. faced immediate litigation from investors alleging the company had artificially inflated its stock price through materially false statements regarding its emissions compliance. The primary consolidation of these claims, Baker v. Cummins Inc. et al. (Case No. 1: 25-cv-00430-TWP-MKK), resulted in a settlement agreement that was preliminarily approved by the U. S. District Court for the Southern District of Indiana on December 15, 2025.

even with the record-breaking size of the regulatory fine, the securities fraud settlement fund was established at $1. 6 million. This figure, significantly lower than typical settlements for regulatory breaches of this magnitude, reflects the specific damages model tied to the stock’s relatively contained volatility, a 2. 87% drop ($7. 01 per share) immediately following the Department of Justice’s announcement. The settlement resolves allegations that executive leadership, including former CEO Tom Linebarger and current CEO Jennifer Rumsey, misled investors about the efficacy of the company’s internal compliance reviews initiated in 2019.

Class Period and Eligibility Criteria

The court-certified settlement class encompasses all persons and entities who purchased or acquired Cummins Inc. (NYSE: CMI) common stock between February 11, 2019, and December 21, 2023. This “Class Period” aligns with the timeline during which Cummins executives purportedly assured the market of their commitment to environmental compliance, while simultaneously continuing to install undisclosed auxiliary emission control devices (AECDs) in RAM 2500 and 3500 trucks.

To participate in the recovery, shareholders must submit valid proofs of claim by the deadline of April 23, 2026. The Final Fairness Hearing, where the court problem a final judgment on the settlement’s adequacy, is scheduled for May 21, 2026.

Compensation Metrics and Per-Share Recovery

The distribution of the $1. 6 million fund follows a pro rata allocation plan, heavily diluted by administrative costs and legal fees. According to the settlement terms, approximately 30% of the fund is for attorneys’ fees, with additional deductions for litigation expenses.

Metric	Settlement Value
Total Settlement Fund	$1, 600, 000
Estimated Net Fund (Post-Fees)	~$1, 025, 000
Estimated Average Recovery Per Share	$0. 14
Recognized Loss Calculation	Lesser of $8. 43/share or purchase price minus sale price
Stock Drop Event	December 22, 2023 (-2. 87%)

The “Recognized Loss” formula specifically shares held through the close of trading on December 21, 2023, and sold shortly thereafter. For shares sold before the corrective disclosure on December 22, 2023, the recognized loss is zero, as the market price was allegedly inflated at both the time of purchase and sale.

Shareholder Derivative Litigation

Parallel to the class action, Cummins faces shareholder derivative lawsuits, such as the complaint filed by the Vladimir Gusinsky Revocable Trust in January 2024. Unlike the class action, which seeks damages for investors, these derivative suits are filed on behalf of the corporation against its own officers and directors for breach of fiduciary duty. The plaintiffs allege that the Board failed to exercise proper oversight, allowing the emissions scandal to fester and resulting in the $1. 67 billion loss to the company’s treasury. As of early 2026, these derivative actions remain active, with plaintiffs seeking governance reforms and the clawback of executive compensation tied to the non-compliant period.

Between Regulatory and Securities Penalties

“The between the $1. 67 billion regulatory penalty and the $1. 6 million securities settlement highlights the mechanical differences in liability. While the EPA punishes the environmental violation itself, securities law only compensates for the specific stock price inflation attributed to the fraud. In this instance, the market’s muted reaction to the fine limited the recoverable damages for shareholders.”

This settlement closes the primary chapter of securities litigation regarding the defeat devices, barring any opt-outs by large institutional investors who might pursue individual actions. yet, the financial recourse for the average shareholder remains minimal, amounting to pennies per share relative to the billions paid to federal and state regulators.

SECTION 14 of 22: Suspension of Share Repurchase Programs Pending use Reduction

Immediate Freeze on Capital Return method

Following the execution of the $1. 675 billion Clean Air Act settlement in January 2024, Cummins Inc. immediately suspended open-market share repurchases to preserve liquidity for the mandated civil penalty and mitigation payments. The company’s Board of Directors halted activity under the 2019 share repurchase authorization, which had approximately $218 million remaining as of December 31, 2022, and the subsequent 2021 authorization of $2 billion.

Financial disclosures from the fourth quarter of 2023 confirm that Cummins ceased discretionary buybacks as the settlement negotiations concluded. This suspension throughout the entirety of 2024, marking the fiscal year in over a decade where the company executed zero open-market repurchases. The freeze was a direct response to the $2. 04 billion charge recorded in Q4 2023, which included the $1. 675 billion penalty and associated recall costs, necessitating a cash outflow of approximately $1. 93 billion in the half of 2024.

use Metrics and Credit Rating Pressure

The settlement triggered an immediate deterioration in Cummins’ use ratios, prompting negative actions from major credit rating agencies. On February 1, 2024, S&P Global Ratings downgraded Cummins’ issuer credit rating from ‘A+’ to ‘A’, citing “increasing regulatory and climate transition risks” and the financial of the settlement. The agency noted that the $2. 04 billion charge pushed the company’s S&P-adjusted debt-to-EBITDA ratio to approximately 1. 5x, a deviation from its historical operating range of well 1. 0x.

To defend the ‘A’ rating, Cummins management committed to a strict deleveraging schedule. The suspension of buybacks was the primary lever used to retain cash flow for debt service and settlement obligations. S&P Global explicitly stated that they did not anticipate material share buybacks until the company’s use returned to 1. 0x. This external credit pressure locked the suspension in place for the 2024-2025 operational pattern.

The Atmus Split-Off: A Non-Cash “Buyback”

While cash repurchases were frozen, Cummins executed a structural reduction in its outstanding share count through the separation of its filtration business, Atmus Filtration Technologies. In March 2024, Cummins completed a tax-free split-off, offering its shareholders the option to exchange Cummins stock for Atmus stock.

This transaction allowed Cummins to retire approximately 5. 6 million shares of its own common stock without a cash outlay. The exchange offer was oversubscribed, resulting in the acceptance of 5, 574, 051 shares. Analysts at Citi characterized this move as an “4% share buyback,” allowing the company to support earnings per share (EPS) metrics even with the suspension of the cash-based repurchase program. This strategic maneuver provided a partial offset to the dilution risks associated with a capital preservation phase.

Share Repurchase Activity vs. Settlement Impact (2021-2025)

Fiscal Year	Cash Used for Repurchases (Millions)	Shares Retired (Millions)	Settlement/Charge Impact	use Ratio (Debt/EBITDA)
2021	$1, 400 (Approx)	5. 8	None	0. 9x
2022	$612	2. 9	None	1. 1x
2023	$4 (Q4 only)	0. 02	$2. 04B Charge Recorded	1. 5x (Pro Forma)
2024	$0	5. 6 (via Atmus Split)	$1. 93B Cash Payment	1. 1x

2025 Deleveraging and Capital Allocation Outlook

By the close of 2024, Cummins had successfully navigated the peak liquidity stress of the settlement. The $1. 93 billion cash payment made in early 2024 was absorbed through strong operating cash flow, which remained strong even with a cyclical downturn in the North American heavy-duty truck market.

Entering 2025, the company maintained its suspension of open-market repurchases to ensure the debt-to-EBITDA ratio stabilized the serious 1. 0x threshold. Financial guidance for 2025 projected a revenue contraction of 2-3%, further incentivizing cash conservation. yet, the company continued its 16-year streak of dividend increases, raising the quarterly payout to $1. 82 per share, signaling that while buybacks were sacrificed for the settlement, direct income returns to shareholders remained protected.

“We believe Cummins continue to curtail share repurchase and acquisition activity until use gets back to historical levels.” , S&P Global Ratings, February 2024.

The oversight of the engine recall program, funded by the preserved capital, remained the operational priority. With the $1. 675 billion penalty paid and the Atmus separation complete, Cummins entered the 2026 planning pattern with a restored balance sheet, positioning it to chance resume discretionary repurchases once the recall completion rates satisfy the 85% threshold mandated by the consent decree.

The recording of a $2. 04 billion charge in the fourth quarter of 2023 fundamentally altered Cummins Inc.’s financial trajectory for the fiscal year, swinging a quarterly operating profit into a deep net loss and consuming of the company’s annual earnings. This charge, recognized in late December 2023, accounted for the $1. 675 billion civil penalty—the largest in the history of the Clean Air Act—and approximately $365 million in associated costs for emissions mitigation projects and recall execution.

Immediate Impact on Q4 2023 Financial Results

The recognition of the settlement liability resulted in a net loss of $1. 4 billion for the fourth quarter of 2023, a clear reversal from the $631 million in net income reported in the same period of 2022. On a per-share basis, the loss amounted to $10. 01 per diluted share, compared to earnings of $4. 43 per share the previous year. The charge decimated the company’s earnings before interest, taxes, depreciation, and amortization (EBITDA) for the quarter. Cummins reported an EBITDA loss of $878 million, or negative 10. 3 percent of sales, contrasting sharply with the positive $1. 1 billion (14. 2 percent of sales) recorded in Q4 2022. Without the $2. 04 billion regulatory charge and other minor separation costs, the company’s underlying performance would have remained profitable, driven by strong demand in North American and international markets. The tax of the settlement further compounded the financial hit. Because the $1. 675 billion civil penalty is non-deductible for federal tax purposes, the company could not use the loss to offset tax liabilities in a standard manner. Consequently, Cummins reported a negative tax rate of 13. 3 percent for the quarter, reflecting the inability to claim tax benefits on the punitive portion of the charge.

Full-Year 2023 Performance Drag

While Cummins achieved record revenues of $34. 1 billion in 2023, a 21 percent increase over 2022, the settlement charge severely eroded full-year profitability. Net income for the full year plummeted to $735 million ($5. 15 per diluted share), a 67 percent decline from the $2. 2 billion ($15. 12 per diluted share) earned in 2022. The between top-line growth and bottom-line contraction highlights the magnitude of the regulatory penalty. even with strong operational execution and the successful integration of Meritor, which contributed to the revenue surge, the settlement wiped out nearly two-thirds of the company’s annual net income.

Metric	Q4 2022 (Actual)	Q4 2023 (Reported)	FY 2022 (Actual)	FY 2023 (Reported)

Cash Flow and 2024 Liquidity

Although the expense was recognized in 2023, the cash impact falls heavily on the half of 2024. Cummins disclosed that approximately $1. 93 billion of the total settlement costs would be paid in cash during early 2024. This massive outflow represents a significant liquidity event, equivalent to nearly half of the record $4. 0 billion in operating cash flow the company generated in all of 2023. To manage this expenditure, Cummins relied on its existing liquidity and credit facilities. yet, the sheer size of the payment drew scrutiny from credit rating agencies. In February 2024, S&P Global Ratings downgraded Cummins’ credit rating from “A+” to “A,” citing the regulatory risks and the substantial cash outlay required to satisfy the judgment. S&P noted that while Cummins maintained a strong balance sheet, the settlement indicated heightened risks associated with environmental compliance and the climate transition.

Stock Market Reaction and Shareholder Sentiment

The market’s reaction to the settlement announcement was immediate relatively contained, suggesting that investors had partially priced in the risk of regulatory action. On December 22, 2023, the day the agreement in principle was announced, Cummins shares fell 2. 87 percent, closing down $7. 01 at $236. 99. even with the initial drop, the stock price recovered in early 2024 as the company provided clarity on the payment schedule and reaffirmed its 2024 guidance. By the time of the Q4 earnings call in February 2024, shares had rebounded, trading above pre-announcement levels. Investors appeared to view the settlement as a “clearing of the decks,” removing the uncertainty of a long-standing investigation that had hung over the company for four years.

2024 Financial Guidance and Outlook

Entering 2024, Cummins management projected a revenue decline of 2 to 5 percent, attributing the softness to a normalizing North American heavy-duty truck market rather than from the settlement. The company forecasted full-year 2024 EBITDA margins between 14. 4 and 15. 4 percent, signaling that operational profitability would remain strong even with the cash flow hit from the penalty payments. The settlement does, yet, impose long-term costs beyond the immediate $2. 04 billion charge. The consent decree mandates extended warranty coverage and ongoing compliance auditing, which add incremental costs to the engine segment in 2024 and beyond. also, the company faces class-action lawsuits from shareholders alleging that management made materially false statements regarding environmental compliance between 2019 and 2023. These legal challenges present a residual financial risk, though they are distinct from the settled government claims.

“Excluding the impacts related to the agreement to resolve U. S. regulatory claims, 2023 was a record year for EBITDA, Net Income and EPS for Cummins.”
, Jennifer Rumsey, Chair and CEO, Cummins Inc., February 6, 2024.

The $2. 04 billion charge serves as a historic financial marker for Cummins, representing the tangible cost of non-compliance with federal emissions laws. While the company’s operational strength allowed it to absorb the blow without an existential liquidity emergency, the settlement fundamentally reshaped its 2023 financial profile and constrained its capital allocation flexibility for 2024.

SECTION 16 of 22: Absence of Criminal Charges and Admission of Wrongdoing

The Civil-Criminal

even with agreeing to the largest civil penalty in the history of the Clean Air Act, Cummins Inc. secured a resolution in January 2024 that stands in clear contrast to its predecessors in diesel emissions scandals: the total absence of criminal charges. The $1. 675 billion payment to the Department of Justice (DOJ) and the State of California is strictly categorized as a civil penalty, a legal distinction that shields the company from the felony convictions that tarnished Volkswagen AG and Fiat Chrysler Automobiles (FCA).

The consent decree filed in the U. S. District Court for the District of Columbia contains explicit language absolving Cummins of formal liability admission. While the company agreed to the record-breaking fine and a $325 million mitigation program, the settlement terms allow Cummins to maintain that it “does not admit wrongdoing.” This “no admission” clause is a standard feature of civil settlements represents a significant strategic victory for the engine manufacturer given the of the violation, involving approximately 960, 000 Ram 2500 and 3500 trucks.

“No Evidence of Bad Faith”

Cummins’ defense strategy centered on the assertion that its engineering teams did not intentionally design the software to cheat emissions tests. In a statement released concurrently with the settlement, the company declared it had “seen no evidence that anyone acted in bad faith.” This narrative distinguishes the Cummins case from the deliberate fraud uncovered in the Volkswagen “Dieselgate” scandal, where engineers created “defeat devices” specifically to recognize test pattern and alter engine performance.

The DOJ’s decision to forgo criminal prosecution suggests that federal investigators either accepted this absence of malicious intent or determined that they could not prove criminal mens rea (intent) beyond a reasonable doubt. Instead of a criminal plea agreement, the government accepted a civil resolution based on the objective fact that the engines failed to meet certification standards during real-world driving, regardless of the engineers’ intent.

Comparative Analysis of Diesel Emissions Settlements

The between the Cummins settlement and previous enforcement actions is clear when analyzing the legal classifications and executive accountability in major Clean Air Act cases.

Table 16. 1: Legal Resolution Comparison , Major Diesel Emissions Scandals (2017, 2024)

Company	Settlement Year	Total Monetary Penalty	Criminal Charges?	Executive Indictments?	Admission of Guilt?
Volkswagen AG	2017	$4. 3 Billion (Civil + Criminal)	Yes (3 Felony Counts)	Yes (Multiple Executives Charged)	Yes (Guilty Plea)
FCA (Stellantis)	2022	$300 Million (Criminal Only)	Yes (Conspiracy)	Yes (Senior Managers Indicted)	Yes (Guilty Plea)
Cummins Inc.	2024	$1. 675 Billion (Civil Only)	No	No	No (Denial of Wrongdoing)

The Role of Voluntary Disclosure and Cooperation

A serious factor in Cummins avoiding criminal liability appears to be its procedural conduct after the discrepancies were identified. Unlike Volkswagen, which initially obstructed justice and destroyed documents, Cummins initiated an internal review in 2019 and voluntarily disclosed its findings to the EPA and the California Air Resources Board (CARB). The company’s cooperation with regulators over a four-year investigation period allowed it to position the violations as technical compliance failures rather than a criminal conspiracy.

Assistant Attorney General Todd Kim of the DOJ’s Environment and Natural Resources Division emphasized the magnitude of the civil penalty as a deterrent, stating it “stands as notice to manufacturers that they must comply with our nation’s laws.” yet, the absence of a criminal probe into individual executives signals that the government prioritized a swift, high-value financial recovery and environmental mitigation over the complex, years-long process of building a criminal fraud case.

Shareholder and Governance

While the settlement closes the door on federal criminal prosecution, the absence of an admission of guilt does not insulate Cummins from shareholder scrutiny. Following the announcement, derivative lawsuits were filed alleging that the company’s directors and officers breached their fiduciary duties by allowing the compliance failures to occur. These civil actions that even without criminal intent, the oversight failures that led to a $2 billion loss (penalty plus remediation costs) constitute a governance breakdown.

The “no admission” clause serves a specific legal utility in these shareholder suits. By refusing to admit liability in the federal settlement, Cummins prevents plaintiffs’ attorneys from using a formal confession of guilt as automatic proof of liability in civil court. This legal firewall forces shareholders to independently prove that executives knowingly ignored red flags, a significantly higher load of proof than simply citing a criminal plea agreement.

Regulatory Precedent

The Cummins resolution establishes a detailed precedent for future environmental enforcement: companies can survive record-breaking penalties without criminal stigma if they self-report and cooperate. It delineates a boundary where “defeat devices” defined by their effect (bypassing controls) are punished civilly, while those defined by intent (designed to cheat) attract criminal prosecution. For the 630, 000 owners of the affected Ram trucks, the distinction is academic; their vehicles require the same software retrofits regardless of whether the code was written with malice or incompetence.

“Cummins knowingly harmed people’s health and our environment… Today’s settlement sends a clear message: If you break the law, hold you accountable.”
, Rob Bonta, California Attorney General (January 2024)

Attorney General Bonta’s use of the word “knowingly” in his public statement contrasts with the federal consent decree’s absence of “bad faith” findings. This rhetorical gap highlights the tension between the political narrative of accountability and the specific legal terms negotiated in the settlement documents. While state officials characterize the actions as knowing violations to satisfy public demand for justice, the binding federal documents reflect a settlement built on strict liability, punishing the act, not the intent.

Comparative Analysis: Cummins Civil Settlement vs. Volkswagen Criminal Liability

The January 2024 settlement between Cummins Inc. and the Department of Justice (DOJ) draws immediate parallels to the Volkswagen “Dieselgate” scandal of 2015. While both cases involve the use of defeat devices to circumvent Clean Air Act standards, the legal outcomes, corporate admissions, and remediation strategies differ fundamentally. The Cummins case represents the largest civil penalty in the history of the Clean Air Act at $1. 675 billion, yet it notably absence the criminal charges that defined the Volkswagen prosecution.

in Legal Liability and Intent

The primary distinction between the two enforcement actions lies in the classification of the violations. Volkswagen AG pleaded guilty to three criminal felony counts, including conspiracy to defraud the United States, obstruction of justice, and entry of goods by false statement. The DOJ proved that Volkswagen engineers intentionally designed software to detect emissions testing pattern and alter engine performance specifically to deceive regulators. In contrast, the Cummins settlement is purely civil. Cummins Inc. has consistently denied “bad faith” and admitted no wrongdoing in the consent decree. The company characterizes the violations as “undisclosed auxiliary emission control devices” (AECDs) that failed to operate as certified during real-world driving, rather than a malicious “switch” designed solely to cheat tests.

The following table outlines the structural differences in liability and penalties between the two entities within the United States jurisdiction.

Table 17. 1: Comparative Liability Profile , Cummins Inc. (2024) vs. Volkswagen AG (2016/2017)

Metric	Cummins Inc. (USA)	Volkswagen AG (USA)
Primary Violation	Civil Clean Air Act Violations	Criminal Conspiracy & Civil Clean Air Act Violations
Criminal Charges	None	Pleaded Guilty to 3 Felonies
Civil Penalty	$1. 675 Billion	$1. 45 Billion
Criminal Fine	$0	$2. 8 Billion
Affected US Units	~960, 000 (RAM 2500/3500)	~590, 000 (2. 0L & 3. 0L TDI)
Remedy Strategy	Software Retrofit (Recall 67A)	Mandatory Buyback & Scrappage
Executive Liability	No Charges Filed	Multiple Executives Indicted/Imprisoned

Scope of Affected Inventory

A serious frequently overlooked is the volume of affected units within the United States. While Volkswagen’s global scandal involved 11 million vehicles, its U. S. footprint for the defeat device covered approximately 590, 000 diesel passenger cars. The Cummins enforcement action covers a significantly larger domestic fleet: 630, 000 engines in the primary defeat device group (2013, 2019) and an additional 330, 000 engines with undisclosed AECDs (2019, 2023), totaling nearly 1 million heavy-duty trucks. even with the higher volume of affected units, Cummins avoided the catastrophic financial load of a buyback program. The technical nature of the Cummins violation allowed for a software-based calibration fix (Recall 67A) to bring emissions into compliance, whereas Volkswagen’s smaller passenger vehicles frequently absence the physical hardware (such as adequate SCR tank volume) to meet standards without severely compromising performance, necessitating a multi-billion dollar buyback.

Remediation Incentives vs. Compensation

The method for consumer restitution highlights the difference in severity perceived by regulators. Volkswagen owners received payments ranging from $5, 100 to $10, 000 to the buyback value of their vehicles. This compensation acknowledged the deception and the loss of vehicle value. Cummins owners, conversely, are being offered a nominal incentive to complete the recall. Under the “Recall 67A” program, Cummins provides a $500 payment to owners who complete the software update, with a temporary increase to $1, 000 for early compliers in early 2026. This payment is structured not as damages for fraud, as a “participation incentive” to ensure the company meets the 85% completion rate mandated by the consent decree.

“The types of devices we allege that Cummins installed in its engines to cheat federal environmental laws have a significant and harmful impact on people’s health and safety… Our preliminary estimates suggest that defeat devices on Cummins engines have caused them to produce thousands of tons of excess emissions of nitrogen oxides.”
, Merrick Garland, U. S. Attorney General (December 2023)

Oversight and Corporate Governance

The post-settlement oversight structures also differ. Volkswagen was forced to retain an independent compliance monitor for three years, Larry D. Thompson, who had broad powers to audit the company’s internal processes and culture. The Cummins consent decree imposes strict reporting requirements and audit for future engine certifications stops short of appointing an external monitor with the same sweeping authority over corporate governance. Instead, Cummins must conduct continuous testing on its repaired fleet to verify that the software updates maintain emissions compliance over time. The 85% recall completion requirement places the duty of performance directly on Cummins’ logistical operations, with stipulated penalties accruing if the target is missed by the three-year deadline.

Technical Architecture of the Defeat method

Technically, the “defeat devices” operated on similar principles with different triggers. Volkswagen’s software utilized steering angle, speed, and barometric pressure inputs to detect a dynamometer test environment, switching to a “lean trap” mode that was never used on the road. The Cummins software relied on “auxiliary emission control devices” that modulated the Selective Catalytic Reduction (SCR) system. These AECDs would reduce the dosing of diesel exhaust fluid (DEF) under specific high-load or temperature conditions common in real-world towing rare in the Federal Test Procedure (FTP). While Cummins argued these were necessary for engine protection, the EPA determined they were unjustified defeat devices because they allowed NOx emissions to spike well above legal limits during normal operation without valid engineering justification.

Regulatory Status of 330, 000 Undisclosed 2020-2023 Models

Differentiation from Defeat Device Violations

The January 2024 settlement distinguishes between two distinct categories of Clean Air Act violations involving Cummins 6. 7L diesel engines. While 630, 000 vehicles from model years 2013, 2019 were found to contain “defeat devices” that actively reduced emission control effectiveness, a second group of approximately 330, 000 vehicles from model years 2020, 2023 faced a different regulatory classification. These units were for containing “undisclosed Auxiliary Emission Control Devices” (AECDs).

Under the Clean Air Act, manufacturers must disclose all software routines that alter engine performance or emissions control strategies during the certification process. Cummins failed to list specific software features in the applications for certification for these 330, 000 trucks. yet, unlike the defeat devices found in the earlier models, federal and state regulators determined that the undisclosed AECDs in the 2020, 2023 fleet did not result in excess nitrogen oxide (NOx) emissions during normal operation. Consequently, these vehicles remain compliant with federal emission standards even with the certification failure.

The October 2019 Production Split

The regulatory boundary between the recall-mandated fleet and the undisclosed AECD fleet occurs within the 2019 model year. This split creates a serious distinction for owners and fleet managers regarding compliance obligations.

Regulatory Treatment by Production Date (2019 Model Year)

Production Period	Violation Type	Regulatory Status	Action Required
On or Before Oct 1, 2019	Defeat Device	Non-Compliant (Excess Emissions)	Mandatory Recall 67A
After Oct 1, 2019	Undisclosed AECD	Certification Violation Only	No Action Required

Vehicles manufactured after the October 1, 2019 cutoff, along with all 2020, 2021, 2022, and 2023 models, are excluded from the retrofit requirements of Recall 67A. The EPA and the California Air Resources Board (CARB) have not mandated a software update or hardware replacement for this specific subgroup.

Exemption from Remedial Action

Because the undisclosed software features in the 2020, 2023 models do not bypass emission controls or cause the vehicle to exceed federal pollution limits, the consent decree exempts these 330, 000 units from the “mitigation program” applied to the older fleet. The 85 percent completion rate requirement, which compels Cummins to repair the majority of the 2013, 2019 trucks within three years, does not apply to the 2020, 2023 population.

“Model year 2020, 2023 vehicles are not subject to the recalls. The recalls ensure the vehicles comply with all the Clean Air Act’s applicable nitrogen oxides (NOx) emission standards.” , U. S. Environmental Protection Agency, January 2024

Owners of these newer models not receive the extended warranty protections granted to the 2013, 2019 owners under the settlement terms. The warranty extension is specifically tied to the installation of the remedial software patch, which is unnecessary for the 2020, 2023 group.

Civil Penalty

Although no physical recall is required, the inclusion of these 330, 000 vehicles significantly contributed to the record-breaking $1. 675 billion civil penalty. The Department of Justice emphasized that the failure to disclose AECDs undermines the integrity of the certification process, regardless of the tailpipe impact. Cummins paid a portion of the total fine specifically to resolve the liability for these certification violations, preventing future litigation regarding the regulatory status of the 2020, 2023 fleet.

As of early 2025, class-action litigation continues to examine whether owners of these undisclosed models suffered “diminished value” or overpaid for vehicles that were technically sold with invalid EPA certificates, even if the engines themselves run clean. yet, no official compensation program has been established for this group outside of the primary government settlement.

The secondary market for 2013–2019 RAM 2500 and 3500 diesel trucks has fractured into a two-tier valuation system following the January 2024 Clean Air Act settlement. While traditional depreciation curves apply to the broader heavy-duty segment, the specific operational penalties associated with Recall 67A—namely increased Diesel Exhaust Fluid (DEF) consumption and reduced fuel economy—have created a distinct pricing wedge between “compliant” (repaired) units and “pre-recall” (unmodified) inventory.

in Wholesale and Retail Valuations

Data from Q1 2024 through Q1 2026 indicates a measurable shift in how these assets are valued across different sales channels. In the wholesale market, specifically at major auction houses like Manheim, 2013, 2019 RAM heavy-duty trucks with the Cummins 6. 7L engine have seen a stabilization in trade-in values, yet they trail behind unaffected competitors such as the Ford F-250 Power Stroke and Chevrolet Silverado 2500 HD Duramax in year-over-year retention percentages. yet, the private party market exhibits a counter- “resistance premium.” Enthusiast communities and independent owner-operators, aware of the performance degradation confirmed in the consent decree (specifically the 0. 5 MPG drop in 2016, 2018 models and increased DEF usage), have begun placing a premium on trucks that have not yet undergone the Recall 67A software update.

Table 1: Valuation Variance by Sale Channel (2013-2018 RAM 2500 Cummins)
Data aggregated from regional auction reports and private listing analysis, Q4 2025.

Sale Channel	Status	Avg. Price Variance (vs. Book Value)	Market Driver
Franchise Dealer (Trade-In)	Unrepaired	-4. 5% to -7. 0%	Dealer liability; mandatory repair cost/time before resale.
Franchise Dealer (Retail)	Repaired (Recall 67A Complete)	-1. 2% (Market Average)	Certified Pre-Owned (CPO) eligibility restored; warranty extension.
Private Party	Unrepaired (“Pre-Recall”)	+3. 0% to +5. 5%	Buyer preference for original fuel economy/DEF rates; avoidance of software lock.
Private Party	Repaired	-2. 0%	Perceived stigma of “neutered” performance; skepticism of long-term reliability.

The “Incentive” as a Depreciation Proxy

By February 2026, the resistance to the recall became financially quantifiable. Cummins Inc. launched a direct cash incentive program, offering $500 to $1, 000 prepaid cards to owners of 2013, 2018 RAM trucks who completed the software update. This unusual move, paying owners to accept a mandatory emissions fix, serves as a direct market signal of the perceived value loss. Economically, this $1, 000 payment functions as a “depreciation offset.” It acknowledges that the market (specifically the owner base) values the vehicle less after the repair than before it, primarily due to the increased operating costs. For a fleet operator running a 2017 RAM 3500, the verified 2. 5% increase in DEF consumption under heavy loads represents a tangible rise in cost-per-mile, which directly the asset’s net present value (NPV).

Market Analysis Note: The need of a cash bounty two years post-settlement suggests that the “take rate” for Recall 67A has lagged behind the 85% compliance target mandated by the DOJ. This lag is driven not by apathy, by an economic calculation by owners who view the pre-recall calibration as a more valuable asset.

Dealer Trade-In Friction and Inventory Stagnation

For franchise dealerships, the 630, 000 affected units present a logistical and financial bottleneck. Federal law prohibits dealers from selling new vehicles with open recalls, and while used vehicle laws vary by state, internal corporate policies at major dealership groups frequently mandate the completion of safety and emissions recalls before a used unit is retailed. This creates a “valuation trap” at the trade-in desk. When a customer presents an unrepaired 2015 RAM 2500, the dealer must factor in: 1. Service Bay Opportunity Cost: The time required to perform the software flash and verify the system. 2. Inventory Hold Time: The risk that the truck may require further diagnostics if the new software triggers latent fault codes (a common occurrence when aging sensors are subjected to stricter monitoring algorithms). 3. Consumer Skepticism: The difficulty of selling a truck with a “fresh” emissions modification to a knowledgeable diesel buyer. Consequently, trade-in offers for these specific VINs have softened. Dealers are pricing in the risk of the recall, offering 4% to 7% standard Black Book values for unrepaired units to insulate themselves from chance post-repair complications.

The California Anomaly: Registration Blocks and Value

In California, the valuation is inverted due to regulatory compulsion. The California Air Resources Board (CARB) holds the authority to block vehicle registration renewals for non-compliant emissions recalls. While the initial 2024 rollout saw a grace period, the tightening enforcement by 2026 has made “compliant” status a prerequisite for legal operation in the state. In this region, an unrepaired truck is a liability rather than an asset. Private party sales of unrepaired units in California have plummeted, as buyers cannot transfer title or renew registration without the Recall 67A certificate. This has led to a migration of unrepaired trucks out of California and into states with laxer emissions enforcement, further distorting regional pricing. A 2016 RAM 2500 might command a $2, 000 premium in Texas (where buyers may intend to keep it unrepaired) compared to California (where it is legally unsellable without the fix).

Long-Term Brand Equity and Residual Value

The $1. 67 billion settlement has also introduced a “stigma discount” to the broader RAM heavy-duty brand equity. Historically, the Cummins engine was the primary value retainer for RAM trucks, frequently commanding a $8, 000 to $10, 000 premium over gas counterparts on the used market. Current auction data suggests this premium is compressing. While the Cummins engine remains desirable for its longevity, the association with “defeat devices” and “emissions cheating” has eroded of the “bulletproof” reputation that supported high resale values. Comparisons with the 2016–2019 Ford F-250 (6. 7L Power Stroke) show that while RAM previously held a slight edge in residual value retention, the two competitors have reached parity, with Ford occasionally surpassing RAM in the 5-year retention index as of early 2026. The market has priced in the reality that the “legendary” pre-2019 Cummins engines were performing at an artificial peak—one achieved by bypassing the emissions constraints that all competitors were adhering to. that the playing field has been leveled via software, the valuation premium has adjusted downward to reflect the true, compliant performance of the hardware.

SECTION 20: State-Level Registration Denials for Non-Compliant VINs

Current Enforcement Status: The “Carrot” Before the “Stick”

As of early 2025, the enforcement method for the Cummins Clean Air Act settlement has created a unique regulatory paradox in California: while the state possesses the statutory authority to deny vehicle registration for non-compliant VINs, the California Air Resources Board (CARB) has initially opted for a voluntary compliance model driven by manufacturer incentives rather than immediate administrative blockades. Contrary to the aggressive registration stops seen in the Volkswagen “Dieselgate” scandal, CARB’s official guidance for the Cummins settlement explicitly states that owners are not currently required to complete Recall 67A to renew their vehicle registration or pass a smog check.

This strategic delay in enforcement is codified in the January 2024 settlement FAQ released by CARB, which provides a categorical “No” to the question of whether the repair is a prerequisite for registration. This decision reflects a phased compliance method designed to allow Cummins to achieve the 85 percent repair rate through financial inducements, specifically the “Recall 67A” incentive program offering $500 to $1, 000 prepaid cards to owners, before the Department of Motor Vehicles (DMV) activates its “registration block”.

The Mechanics of Future Denial: DMV “Stop” Codes

While the immediate registration block is dormant, the infrastructure for its activation is fully operational within the California DMV’s Vehicle Registration (VR) system. Under California Vehicle Code (CVC) Section 4755, the DMV is authorized to refuse registration renewal for any vehicle with an outstanding emissions recall. The method relies on a data exchange pipeline where Cummins must provide CARB with a monthly “Proof of Correction” list of VINs that have successfully received the software update.

When the “stick” phase of enforcement is eventually triggered, likely if Cummins fails to meet interim repair , the DMV flag non-compliant VINs with a specific “EM” (Emission) stop code. This code prevents the automated renewal of registration tags online or at kiosks. Affected owners would receive a “Vehicle Registration Renewal Notice” with a distinct warning: “Registration Renewal Blocked: Open Emissions Recall.” To clear the flag, the owner must present a physical “Vehicle Emission Recall Proof of Correction” certificate (issued by the dealer upon completion of Recall 67A) to a DMV field office or wait for the dealer’s electronic update to propagate through the CARB database, a process that can take up to 30 days.

Indirect Registration Blocks: The OBD Monitor Trap

even with the absence of a direct administrative block for the recall code itself, owners of 2013, 2019 RAM 2500 and 3500 trucks are encountering de facto registration denials through the state’s biennial smog check program. The technical remedy for Recall 67A involves a complete re-flash of the Engine Control Module (ECM), which inadvertently wipes the vehicle’s On-Board Diagnostic (OBD) “readiness monitors.”

California’s smog check stations are legally prohibited from passing a vehicle if these monitors, self-tests that verify the function of emissions components like the SCR catalyst and particulate filter, are not set to “Ready.” Because the 6. 7L Cummins engine requires a complex, multi-phase drive pattern to reset these monitors (frequently requiring highway driving under specific load conditions), owners who perform the recall shortly before their registration deadline are failing their smog checks. Consequently, the DMV denies registration renewal not because of the open recall per se, because the vehicle cannot produce a passing smog certificate. This technical catch-22 has forced thousands of owners into a regulatory limbo, requiring them to obtain temporary operating permits (TOPs) while they attempt to drive their trucks enough to reset the monitors.

Section 177 States and Cross-Border Enforcement

The enforcement extends beyond California to the “Section 177” states, jurisdictions that have adopted California’s stricter emissions standards, including New York, Massachusetts, and Washington. While these states have not yet issued independent registration denial orders for Recall 67A, their environmental agencies are bound by the same consent decree terms.

Historically, Section 177 states follow California’s lead with a lag time of 6 to 12 months. If CARB flips the switch to mandatory registration denial, these states are expected to reciprocate, creating a coastal blockade for non-compliant RAM trucks. This is particularly serious for the secondary market; a non-compliant truck registered in a state without denial method (like Texas or Florida) cannot be legally imported and registered in a Section 177 state until the recall is performed, devaluing the asset for cross-border resale.

The 85 Percent Trigger

The timeline for shifting from voluntary incentives to mandatory registration denial is inextricably linked to the “85 Percent Repair Threshold” mandated by the consent decree. Cummins has a three-year window (ending in early 2027) to remediate 85 percent of the affected 630, 000 vehicles. If the voluntary uptake stalls, the Department of Justice and CARB retain the authority to petition the court for “additional injunctive relief.”

Legal analysts anticipate that if the repair rate trails projections by the end of 2025, CARB revoke the current “No” guidance and instruct the DMV to begin rejecting renewals. This creates a ticking clock for owners: the $500 incentive is a temporary offer, the eventual requirement to perform the update to keep the truck on the road is a near-certainty if voluntary compliance creates a shortfall in the emissions mitigation.

Jurisdiction	Current Status (2025)	Enforcement method	Trigger for Denial
California (CARB)	Voluntary / Incentivized	DMV “EM” Stop Code	Failure to meet annual repair
Section 177 States (NY, MA, WA, etc.)	Voluntary	Reciprocal Registration Block	Activation of CARB denial
Federal / EPA Only States	Voluntary	None (Federal absence of DMV authority)	N/A

“The state of California was not going to allow me to renew the registration until the emissions recall was completed… What I failed to consider was when the recall flash was completed it wiped out all the emissions monitors… I was again required to obtain a smog inspection.”

SECTION 21 of 22: Capital Expenditure Reallocation Toward Accelera and Hydrogen

Financial Recalibration: The “Destination Zero” Reality Check

Following the $1. 675 billion Clean Air Act settlement, Cummins Inc. executed a sharp strategic pivot in its capital allocation for the 2024, 2025 fiscal period. While the company publicly maintained its “Destination Zero” decarbonization roadmap, internal financial maneuvers reveal a significant retrenchment from aggressive hydrogen expansion in favor of “fuel-agnostic” internal combustion platforms. The settlement, recorded as a $2. 04 billion charge in Q4 2023, stripped liquidity from the company’s balance sheet just as its zero-emission division, Accelera, required massive capital injections to.

By the close of 2025, Cummins had fundamentally restructured its investment thesis. The aggressive projection made during the 2020 “Hydrogen Day”, which targeted $400 million in electrolyzer revenue by 2025, collapsed under the weight of market realities and regulatory penalties. Instead of the exponential growth forecast, Accelera reported a segment EBITDA loss of approximately $438 million for the full year 2025, forcing leadership to “pace” investments and prioritize immediate profitability over speculative green hydrogen market share.

The Atmus Divestiture: Liquidity for Liability

To offset the cash impact of the civil penalty and fund ongoing operations without slashing core R&D, Cummins monetized its filtration business. The separation of Atmus Filtration Technologies (NYSE: ATMU), completed in March 2024, served as a serious liquidity event.

Table 21. 1: Financial Impact of Atmus Separation vs. Settlement Costs (2023, 2024)

Financial Event	Transaction Value	Strategic Implication
Clean Air Act Settlement	($1. 675 Billion) Cash Outflow	Immediate reduction in free cash flow available for high-risk R&D.
Atmus IPO & Split-Off	~$1. 3 Billion Net Gain	Cash and debt retirement used to stabilize balance sheet post-fine.
Accelera Reorganization Charge	($312 Million) Expense	Cost of downsizing zero-emission operations to align with slower demand.

The $1. 3 billion gain from the Atmus split-off was not funneled entirely into new hydrogen projects, as originally anticipated by market analysts. Instead, was absorbed by the settlement obligations and the need to shore up the “Engine” and “Power Systems” segments, which generate the actual cash flow required to pay the fine. This capital shuffle delayed the standalone viability of the Accelera unit.

Retreat from Electrolyzer Manufacturing

In a definitive move signaling the end of its “growth at all costs” phase for hydrogen, Cummins announced in early 2026 (reflecting on 2025 performance) a halt to future commercial activity in its electrolyzer business. This decision marked a reversal of the strategy championed in 2020, 2022, where Cummins sought to lead the U. S. market in green hydrogen production hardware.

The retreat was driven by two primary factors:

“The adoption of certain zero-emissions solutions has slowed in regions… We have commitments to customers that we’ve made, stop future commercial activity.” , Jennifer Rumsey, Chair and CEO, regarding the Accelera restructuring (February 2026).

The “halt” applies to new sales of proton exchange membrane (PEM) electrolyzers for utility- projects, a sector plagued by high interest rates and the slow rollout of Department of Energy (DOE) hydrogen hubs. Consequently, the capital expenditure (CapEx) originally earmarked for expanding electrolyzer manufacturing capacity in Minnesota and Spain was reallocated. The 2025 CapEx budget of $1. 2 billion was heavily weighted toward the “HELM” engine platforms, diesel, natural gas, and hydrogen-combustion engines, rather than fuel cell stacks.

The HELM Platform: A Over the Cash Crunch

With the $1. 67 billion penalty necessitating disciplined capital management, Cummins pivoted back to its core competency: internal combustion. The launch of the HELM (Higher Efficiency, Lower Emissions, Multiple Fuels) platforms, specifically the X15N and X10 engines, represents a ” strategy.”

Unlike the capital-intensive Accelera division, which burned cash with negative margins, the HELM platforms use existing manufacturing footprints and supply chains. In 2025, the Engine Segment generated segment EBITDA margins of approximately 13. 5%, providing the necessary funds to service the settlement payments. The strategy concedes that the transition to zero emissions be longer than predicted, requiring a prolonged reliance on revenue from diesel and natural gas engines to subsidize the company’s regulatory debts and future tech development.

Accelera Segment Performance (2024, 2025)

The financial performance of the Accelera segment during the settlement payout period illustrates the on Cummins’ resources. even with revenue growth in e-mobility components, the segment remained deeply unprofitable.

• 2024 Segment Loss: $431 million EBITDA loss on $34. 1 billion total company revenue.
• 2025 Segment Loss: $438 million EBITDA loss on $33. 7 billion total company revenue.
• Reorganization Costs: In Q4 2024 and Q1 2025, Cummins incurred over $450 million in charges related to impairing assets and severing staff within the Accelera division.

These losses confirm that the “Clean Air Act settlement era” at Cummins is characterized not by an acceleration into green energy, by a consolidation of resources. The company has paused its transformation into a hydrogen giant, choosing instead to secure its survival through the optimization of the very diesel technology that led to the oversight emergency in the place.

SECTION 22 of 22: Projected Financial Exposure Beyond the $2 Billion Provision

The $2. 04 Billion Provision: A Ceiling or a Floor?

In the fourth quarter of 2023, Cummins Inc. recorded a charge of approximately $2. 04 billion to resolve U. S. regulatory claims regarding its emissions certification and compliance processes. This provision was structured to cover the record $1. 675 billion civil penalty payable to the Department of Justice (DOJ) and California Air Resources Board (CARB), alongside an estimated $326 million allocated for recall execution, mitigation projects, and corporate compliance measures.

yet, an analysis of legal proceedings and operational data through February 2026 indicates that this financial shield is porous. The provision primarily addresses government sanctions, leaving the company exposed to significant unprovisioned liabilities arising from consumer class actions, cost overruns in the recall program, and extended warranty obligations. The emergence of a new incentive program in early 2026 suggests that the initial cost estimates for remediating the 630, 000 affected RAM trucks were optimistic.

Unresolved Consumer Class Action Liability

The most substantial financial threat to Cummins beyond the government settlement lies in the consolidated consumer class action litigation, In re Cummins Inc. Emissions Litigation (including Biederman et al. v. FCA US LLC et al.). Unlike the Volkswagen “Dieselgate” scandal, where consumer compensation was negotiated concurrently with government fines, the January 2024 consent decree explicitly stated that it did not resolve claims for “restitution, refunds, rescission, damages, [or] disgorgement” held by individual consumers.

On February 11, 2025, U. S. District Judge Jacqueline Scott Corley issued a pivotal ruling in the Northern District of California, denying Cummins’ motion to dismiss roughly half of the plaintiffs’ claims. The court allowed allegations based on California consumer protection laws, specifically the Unfair Competition Law and False Advertising Law, to proceed. The survival of these claims exposes Cummins to chance damages for the diminished value and performance of over 600, 000 vehicles.

If a settlement or judgment mirrors even a fraction of historical precedents, the financial impact could be severe. A payout of $1, 000 per vehicle, conservative compared to the $5, 100 to $10, 000 range seen in the VW 2. 0-liter settlement, would generate an additional liability of $630 million. This figure is entirely separate from the $1. 675 billion penalty and sits outside the scope of the original 2023 provision.

Recall 67A Cost Overruns and the $500 Incentive

Operational data from early 2026 suggests that the $326 million allocated for recall execution is insufficient. The consent decree mandates an 85 percent completion rate for Recall 67A by January 2027. To accelerate compliance, Cummins launched a significant financial incentive program in February 2026.

Under this program, owners of eligible 2013, 2018 RAM 2500 and 3500 trucks who complete the software update receive a $500 prepaid Mastercard. Early participants were offered up to $1, 000.

Projected Cost of Recall Incentives (Non-Provisioned)

Scenario	Participation Rate	Est. Vehicles	Cost per Unit	Total New Liability
Low Uptake	30%	189, 000	$500	$94. 5 Million
Target Uptake	50%	315, 000	$500	$157. 5 Million
High Uptake	85% (DOJ Mandate)	535, 500	$500	$267. 7 Million

If 85 percent of the fleet claims the incentive to meet the federal mandate, the direct cash outlay would method $268 million. This single line item nearly consumes the entire $326 million originally budgeted for all recall expenses, which must also cover dealer labor ( 0. 5 to 1. 0 hours per truck), hardware replacements for 2013, 2015 SCR catalysts, and the $175 million mitigation payment to California. The mathematics imply a deficit of hundreds of millions of dollars in the recall budget.

Securities Litigation Settlement

While consumer liability remains an open wound, Cummins has moved to close its exposure to shareholders. In December 2025, the U. S. District Court for the Southern District of Indiana granted preliminary approval to a settlement in the securities class action Baker v. Cummins Inc. The company agreed to pay $1. 6 million to resolve claims that it made materially false statements regarding its emissions compliance between 2019 and 2023.

While this sum is negligible relative to the DOJ penalty, it establishes a record of the “fraud-on-the-market” allegations. The settlement, scheduled for a final fairness hearing on May 21, 2026, releases the company from further shareholder claims related to the stock price drop, capping this specific avenue of financial risk.

The Nissan Titan “Add-On” Penalty

The $2. 04 billion provision was further eroded by a separate settlement finalized in March 2024 involving the Nissan Titan. Cummins agreed to pay $46 million to CARB and the California Department of Justice to resolve violations involving 120, 000 engines in 2016, 2019 Nissan Titan trucks.

These engines contained undisclosed Auxiliary Emission Control Devices (AECDs) similar to those in the RAM fleet. Although smaller in, this settlement demonstrates that the regulatory scrutiny extends beyond the RAM platform. The $46 million payout, combined with the recall costs for these 120, 000 units, places additional on the company’s reserves.

Long-Tail Warranty Exposure

The consent decree imposes an extended warranty on all repaired vehicles, covering the expensive Selective Catalytic Reduction (SCR) system and related sensors. For the 2013, 2015 model years, which require hardware replacement, the warranty risk is contained. yet, for the 2016, 2019 models receiving only software updates, the risk is elevated.

Field that the new calibration increases Diesel Exhaust Fluid (DEF) dosing rates to control NOx. Higher DEF consumption places increased stress on the dosing injectors and pumps. If these components fail prematurely due to the aggressive new software strategy, the costs fall under the mandatory extended warranty. With replacement costs for SCR components ranging from $1, 200 to $3, 000 per unit, a failure rate increase of just 5 percent across the 630, 000-vehicle fleet would generate over $50 million in unplanned warranty claims.

Summary of Financial Exposure

“The $2. 04 billion charge was a down payment, not a final invoice. Between the active consumer class action, the $260 million incentive program, and the Nissan settlement, Cummins faces at least $500 million to $1 billion al exposure through 2027.”

The financial book on the Cummins emissions scandal is far from closed. While the DOJ and EPA have collected their fines, the private sector liability is only beginning to materialize. The February 2025 court ruling preserving consumer fraud claims ensures that legal fees and chance damages load the balance sheet for years to come. also, the introduction of cash incentives in 2026 signals that the physical execution of the recall is proving more difficult, and expensive, than anticipated.
