2022 JEEP GRAND WAGONEER Engine Problems

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 contact owns a 2022 Jeep Grand Wagoneer. The contact stated while driving at approximately 80 MPH, the vehicle stalled. The contact stated that the message "Shift to Park and Restart" was displayed. The contact was able to coast to the side of the roadway and shifted to park(P). The contact was able restart the vehicle and continued driving. The vehicle was taken to a dealer, where the failure could not be duplicated; however, the failure recurred while driving. The message "ACC Disabled" was displayed, and the power steering warning light was illuminated. The contact was able to restart the vehicle; however, the vehicle went into Limp mode and failed to exceed 15 MPH. The vehicle was taken to a different dealer, where the failure could not be duplicated. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 33,000.

I was told the vehicle has a TSB out for stuck thermostat in the engine. It can cause malfunctions, overheating, etc. we also have an issue with the trunk door not closing or opening properly due to a module issue.

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.

Car started displaying all Mill lights in the message center, including “lane assist disabled,” “stability control arm needs servicing,” “traction control unavailable,” and others. After about 3-5 seconds of rapid fire messages being displayed, the car made a “shutting down noise” and then died on the side of the road. Had it towed to a dealership.

AC/HVAC: experienced multiple occasion where the system (front and rear) turns on and quickly varies between settings with no way to override. Engine: when speeds are in excess of 80mph front passenger vent makes excessive noise in line with engine rpm’s “Auto drove” ineffective due to lane departure inop, after service for above incidents Radio is extremely intermittent.

2022 Jeep Grand Wagoneer series 1,had 22000 miles and engine locked up with number 4 piston seizing up. New starter put on and also new Cadillac converters. A new motor was installed but will not idle because of timing issues. 64 days later engineer can still not figure out how to help the mechanic to get it running. Prior to this driving home from dealer lot airbag light came on SOS. Would shift in four low without pushing the button while driving. Because dealership was not a Certified Jeep Wagoneer dealer, wagoneer client services has been little to no help driving a used GMC Arcadia that has more miles on it that what our vehicle had when the motor blew!

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...

While I was driving at around 35 miles per hour and tried to stop in a short distance because of the “should I go or not” situation at the traffic light, the whole vehicle was shut off at a blink of an eye. Soon after I noticed it and tried to imitate the incident to make sure I wasn’t mistaken, it happened three time in a row. The incident can only be seen at night time when light from the headlight is visible since it happens so quick. It wasn’t just about headlight. The engine shut off and turned back momentarily as well. Thankfully each event didn’t last longer than a second and there weren’t any vehicles nearby. When I told a CDJR Monrovia service department manager about the incident and said we need to investigate, he was not serious about it. And nothing was inspected upon the request. There...
