Dear NHTSA, I am filing this complaint regarding a serious and ongoing turbocharger and engine problem in my 2022 Jeep Grand Wagoneer. Despite being one of Jeep’s flagship luxury vehicles, my SUV has experienced repeated engine warning lights, loss of power, and now complete turbo failure—all within 57,300 miles and under warranty. Soon after purchase (used, low mileage), the check engine light began appearing repeatedly. The dealership (Jeep Pearson, Broad Street, Richmond, VA) performed several repairs and software resets, but the problem always returned. Recently, I was informed that the turbocharger must be replaced—an alarming issue for such a premium vehicle. These failures have created safety risks including: Sudden loss of acceleration while driving on highways or merging. Hesitation or delayed throttle response, leading to unpredictable behavior in traffic. Concern about engine stalling or overheating from repeated malfunction. I have already escalated the issue to Jeep Brand (Stellantis) and requested the following: Vehicle replacement with a safe, defect-free model; Buyback and loan payoff to remove liability from a defective vehicle; or Two-year warranty extension covering all turbo and powertrain components. Despite multiple service visits and my written escalation, Jeep has not provided a permanent fix or assurance that the problem won’t return after repair. My warranty is nearing expiration, leaving me at risk of future costs caused by what appears to be a manufacturing defect. Through online research and owner discussions, I’ve found other Grand Wagoneer owners reporting similar turbo failures, power loss, and recurring check-engine issues, often before 60,000 miles. This suggests a potential systemic defect that could compromise safety across the 2022 Grand Wagoneer line. I respectfully ask NHTSA to Investigate turbo and powertrain reliability in 2022 Jeep Grand Wagoneers.

While traveling on San Marcos Highway between Luling and San Marcos at 65 MPH, the vehicle began to lose speed and I realized the engine was no longer powering the vehicle. No warning indicators other than an unresponsive throttle. I was able to coast off onto the shoulder and bring the vehicle to a stop. The dash prompted me to put the vehicle in park before starting so somehow the vehicle turned off while driving. I have experienced numerous electrical nuances with this vehicle, but mainly to the comfort systems (A/C, radio), but a vehicle randomly turning off while driving is what prompted me to file this report.

The engine in our 2022 Wagoneer failed. We bought the car on April 30, 2022 and it had 15,000 miles on it when the engine blew. We were driving on I-70 near Burlington, CO when the message on the did ash read something to the effect of put the car in park. There were no other warning lights. Immediately, the car began to lose power and white smoke started to come out of the exhaust. We were able to get the car to the shoulder from the left lane, however, we were going 75mph or so and could’ve gotten into a wreck. A wrecker was called through Wagoneer roadside assistance and came about 2 hours after the initial call. The anti lock brakes on the car kept locking when the car was put into neutral to try to get the car on the wrecker. The engine barely started at this point. The closest dealer was in limon, co which is where the car is currently. Upon visual inspection, a new engine was ordered under warranty. Apparently, the engine was completely locked at this point and the service dept in Limon couldn’t even start the car. We don’t know if there is anything else wrong. Additionally, there is another Wagoneer at the Transwest dealership in limon, co with a blown engine.
