2022 Jeep Grand Wagoneer: check engine light

Filed Sep 30, 2026 · Fuel system · NJ

I am reporting a serious and recurring safety issue involving my 2022 Jeep Grand Wagoneer. The vehicle currently has approximately 95,000 miles. On the first incident, the vehicle became disabled and gasoline was pouring from the rear of the vehicle. Police and fire personnel responded and the vehicle had to be towed to the dealership. The dealership’s repair documentation states that the vehicle was brought in as a no-start with gas pouring from the rear and that technicians “found fuel line disconnected.” The fuel line was resecured. Shortly after that repair, the same serious problem occurred again. The vehicle again became disabled and leaked a substantial amount of gasoline. Police and fire personnel responded again, and the vehicle was towed back to the dealership. During the second repair, the dealership diagnosed another fuel tube issue and replaced two fuel-system components/fuel tubes. The vehicle remained at the dealership for approximately ten days. I picked up the vehicle on September 30, 2026. After driving approximately 60 miles, the Check Engine light illuminated again. Because both previous incidents began with a warning light and subsequently resulted in the vehicle becoming disabled and leaking gasoline, I do not believe it is safe to start or drive the vehicle. I am particularly concerned that the vehicle could suddenly become disabled while traveling on a highway or in heavy traffic, creating a serious risk to the occupants and other motorists. I am also concerned about the fire hazard associated with the repeated fuel leakage. This vehicle has already undergone two repair attempts relating to this fuel-system problem, yet a warning light has returned immediately after the most recent repair. I am requesting that this matter be formally documented as a recurring fuel-system safety issue, escalated for technical review by the manufacturer, and thoroughly investigated to determine the root cause before the vehicle is returned to service.

I am filing this complaint because my Grand Wagoneer has experienced repeated, serious safety-related failures involving the braking system, electrical/communication systems, and vehicle shutdown. I no longer believe this vehicle is safe to operate. The most serious problem has occurred more than once. On July 21, 2026, while driving, the brakes failed. The brake pedal went to the floor and the vehicle would not stop normally. Multiple warning lights/messages appeared. I ultimately had to shift the vehicle into Park to prevent a collision. The vehicle was taken to the Jeep dealership and remained there for an extended period while the problem was investigated. The dealership reported that it could not identify stored diagnostic codes explaining the brake failure. I was told that the brake pads and rotors needed to be replaced before the matter could be escalated further. I authorized approximately $2,000 in brake-related repairs. After an extended stay at the dealership, I received the vehicle back on approximately September 1, 2026. Only approximately two days later, on September 3, 2026, another extremely serious failure occurred. While I was driving, the braking system failed again. The brake pedal went to the floor and I was unable to stop the vehicle normally. The vehicle also experienced an electrical/system failure and shut down while I was driving. Numerous warning messages appeared, including a check-engine warning and suspension/damping system failure. There was also a loss-of-communication fault involving the Body Control Module (U0140 – Lost Communication With Body Control Module). This incident occurred near my daughter’s school and created an immediate risk of a collision and serious injury. The vehicle subsequently restarted, but the clock/time in the vehicle had changed, suggesting that the vehicle may have experienced a significant electrical interruption or module reset. The check-engine light remained illuminated. Other electrical problems

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 the federal safety agency to Investigate turbo and powertrain reliability in 2022 Jeep Grand Wagoneers.

Our car is now having two issues: 1. The first issue is extremely scary, but we found a temporary work around so have been dealing with it for months as we needed are car. If the auto stop/start is not turned off (which has to happen ever time the car is started), the car essentially puts on an emergency break and shuts down the car at the first for second stop. This happened in the middle of a busy intersection the first time and happened numerous other times including while I was on the phone with the Jeep dealership. It is extremely dangerous as you can be stuck at a stop light in the middle of the road and the car has to be turned off and turned back on. We drive on [XXX] in michigan daily for work and it is a 55mph road with dozens of stop lights making this a huge safety hazard. I have seen numerous other people on a Jeep Wagoneer facebook page with the same issue. 2. The second issue is more recent, but has made the car un-drivable. While driving suddenly the "service fuel system" alert comes on with the check engine light flashing and the car feels like it is going to stall out, then it will regulate and the alert will go away, then it will come back a minute later. We immediately drove our car to the dealership as it was not drivable that way and they have had it for 3 weeks unable to find a fix. We put premium 93 gas in our car and it has not been in any accidents. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

2022 Jeep Grand Wagoneer Series II. THIA WHOLE VEHICLE IS A DEATH TRAP!! Since owning this vehicle it's been one issue after another with one dealership visit "repair" after another. With each repair the vehicle gets worse and the problems aren't fixed. My vehicle has been in & our of service over 20 times in the passed year. We even had it in for a 10 hour repair, where they said they fixed "all the technology". But that still doesn't work. We had it upgraded, but that doesn't to make anything better... It's slower than molasses & freezes - but that is the least of my issues... It seems like The dealership is doing nothing to help me & just putting Band-Aids on these issues, so I've finally decided to open my mouth. Not only are "minor issues" such as the radio not getting fixed, there are issues like my check engine light constantly coming on, my power steering going while driving, heating/cooling seats turning on and off whenever they feel like through out the drive & the adaptive cruise control frequently decides not to work. This vehicle is going to kill me and my family because everyone is downplaying how serious everything is, mind you the power steering went out while I WAS DRVING my soon to football. This whole vehicle should be recalled. I thought I was going to love this car, but it has been nothing but a nightmare! my jeep is back in service for the power steering issue. Who knows how long it will be there. Or they may give it back and say "hey, it's good." like they've been doing. BUYER BEWARE. if you're thinking a grand wagoneer.. think again!!
