NHTSA Complaint #11681112 — 2018 JEEP GRAND CHEROKEE

The vehicle experienced a failure of the engine lifters/rocker arms, which also caused failure of the intake camshaft. This resulted in severe misfires, loss of power, and left the vehicle completely inoperable. The failure created a hazardous situation when the vehicle lost acceleration and was unable to maintain safe driving speeds, placing my safety and the safety of others at risk of collision. The problem was confirmed by Lou’s Car Care and multiple Stellantis dealerships, including Maguire Chrysler Dodge Jeep Ram. All inspections identified failed rocker arms/lifters and the intake camshaft as the cause of the malfunction. Critically, Stellantis no longer produces replacement intake camshafts for this engine, and the part is listed as indefinitely back ordered and unavailable. This means there is no factory fix, leaving the vehicle permanently disabled. Prior to the failure, the only symptom was a faint ticking noise from the engine. No warning lights or dashboard messages appeared before the incident. The problem escalated suddenly without adequate warning, causing the vehicle to lose power unexpectedly. This failure has caused severe negative consequences for me and my family. Because the vehicle became inoperable and the repair could not be completed, I lost my job due to lack of reliable transportation. I also experienced financial hardship, including losing my vehicle to repossession. My family, including my newborn child, was left without dependable transportation, which created additional safety concerns in emergencies. The failed components remain available for inspection upon request. This issue is widespread across Stellantis vehicles yet has not been addressed through a recall, despite the fact that the defect can cause sudden stalling or total engine failure at unsafe speeds. The unavailability of replacement camshafts means affected vehicles cannot be repaired at all, leaving owners stranded and financially devastated.
