In 2022, I paid over $15,000 to an official Jeep dealership (Chrysler Dodge Jeep RAM City, Greenwich CT) to replace the engine in my Jeep Wrangler. Without clear disclosure or consent, they installed a non-OEM Jasper remanufactured engine. The invoice misleadingly stated aœALL PARTS ARE NEW UNLESS OTHERWISE INDICATED,a with no mention of Jasper or warranty terms. The vehicle began malfunctioning almost immediately, raising multiple serious safety concerns, confirmed by written service exchanges: a¢aœThe Jeep is stopping alone! Just crazy, brakes come on alonea a” 🛑 Spontaneous brake engagement poses a serious crash risk. a¢aœIt also smells strong gas when turning the car ona a” 🚨 Potential fuel leak or misfire, which is a fire hazard. a¢aœThe Jeep is malfunctioning,a aœcheck engine light came back on,a aœneeds a PCMa, followed by: aœIam not sure this is a computer problem, but the motor you folks placed in the car.a a” aš ï¸ Suggests deeper integration issues between the engine and vehicle electronics. After only ~8,000 miles, the engine failed again. I spent thousands more with an independent mechanic, who found that several parts supposedly replaced in 2022 were already failing again (spark plugs, oil cooler, manifold gaskets, thermostat). This points to reused components, poor-quality parts, or improper installation. Stellantis refuses to assist, claiming their dealership is aœindependent,a despite operating under Stellantis branding and authorization. A Stellantis rep confirmed they would only file an internal complaint and left me to handle everything alone. This reflects mechanical negligence, brand-level accountability failures, and clear safety threats. Iam requesting NHTSA investigate: a¢Post-engine replacement safety hazards and quality of work and materials a¢Dangerous servicing practices at this authorized dealership (if not many or all of them) a¢Stellantisa lack of oversight over branded repairs
