The class action centers on allegations that certain 2014–2019 Ram 1500 EcoDiesel trucks (built between June 12, 2013 and October 23, 2019) were equipped with exhaust gas recirculation (EGR) coolers prone to thermal fatigue. Plaintiffs claim repeated heating and cooling can cause the cooler to crack, allowing coolant to leak into the intake system; in worst-case scenarios, that mixture can contribute to combustion in the intake manifold and even vehicle fires. FCA US denies wrongdoing and the court has not ruled on the merits, but the case is moving forward as a proposed settlement. The lawsuit was filed to secure repairs and compensation for owners facing a safety-related risk and the costs that can come with it—towing, rentals, coolant loss, and in rare cases fire damage—without each owner having to sue individually. Instead of creating a large cash pool, the settlement’s main relief is a warranty extension tied to EGR cooler replacements under Recall VB1, plus reimbursement for certain out-of-pocket expenses subject to a $750,000 cap and a $3,000 payment option for qualifying fires attributed to EGR cooler failure; claims must be submitted by May 16, 2026 with documentation for reimbursement and fire claims. More broadly, the case fits a common pattern in modern automotive litigation where emissions-control components (like EGR systems used to reduce NOx) become the focus not just for performance concerns but for safety and reliability, intersecting with the recall process and federal vehicle safety oversight that encourages manufacturers to address defect-related fire risks through recalls, extended warranties, and standardized consumer remedies.
