2022 Jeep Wagoneer engine problems

“To Whom It May Concern, I am writing to report a serious safety concern involving my Jeep Wagoneer. The vehicle has experienced intermittent stalling issues, creating a hazardous driving situation and leaving me stranded. The vehicle unexpectedly stalled, causing a loss of power and leaving me without reliable transportation. Given the potential safety risks associated with a vehicle stalling while in operation, I am extremely concerned about the possibility of this occurring again, particularly in traffic or at highway speeds. Adding to my frustration, after contacting the dealership for assistance, I was informed that it would be approximately eight days before the vehicle could even be inspected. A delay of this length for a vehicle experiencing a potentially dangerous drivability and safety issue is unacceptable and leaves me without confidence in the safety and reliability of the vehicle. I am requesting that this matter be investigated promptly and that appropriate action be taken to address the stalling condition. I also believe this issue warrants review for any potential broader safety concerns affecting other Jeep Wagoneer owners. Please document this…”

“- [ ] U1412 implausible vehicle speed signal received - [ ] U0402 implausible data received from tcm - [ ] P0562 battery system/voltage low - [ ] P032f combustion engine producing insufficient torque Car completely shut off when attempting to turn onto Route 73 in NJ. The car was stuck in the intersection causing a threat to life and well-being of those not only in the Wagoneer but to the other drivers as the car could not be moved until towed. This took over an 1.5 hours to get towed and traffic had to be diverted by police.”

“The contact owns a 2022 Jeep Wagoneer. The contact stated that while driving under 5 MPH, the vehicle shut off and was rear-ended by a pickup truck. The vehicle was towed to an undisclosed location. The low battery reserve message was displayed afterwards on two occasions. The contact stated the failure was like the failure listed in NHTSA Action Number: PE24018 (ELECTRICAL SYSTEM, HYBRID PROPULSION SYSTEM, ENGINE, ENGINE AND ENGINE COOLING). The Jeep manufacturer was contacted by phone on several occasions, and the contact spoke with a representative. The local dealer associated the failure with the auxiliary battery. The contact was informed that the auxiliary battery needed to be replaced. The failure mileage was approximately 82,000.”

“Battery light came on and showed low voltage while driving down the highway along with a loud sound. Also the icon with a red A and a circle around it came on, the lights and icons starting signaling. The steering wheel instantly became difficult to turn and control. I started to pull off the road the best I could and the parking break engaged before I could come to a complete stop. I wasn’t even off the road before the vehicle came to a stop.”

“My car blew an engine while I was inside the car. The car was in park and running in a parking lot when the parking brake automatically engaged unexpectedly. Then, the gauge cluster instructed me to press the brake and push the start/stop button. I then got a warning on my gauge cluster, this time notifying my car entered starter protection mode. Repeating the process three times, me, my four year-old daughter, and were put at high risk of suffering burns as my car started to give off a burning smell of oil, as well strong white smoke from the hood, and shut off the car and opened the hood to release the smoke. If I had waited longer, there would have been a fire. The car is available upon inspection and is currently at my local dealer as of 8/11/2026 (Thunder Chrysler Dodge Jeep Ram, Bartow, Florida) for repairs. An engine failure was confirmed by discoveries by the dealer of a broken valve spring, a dropped cylinder, a cracked piston head, and an oil-coolant mixture. The dealer confirmed that this stemmed from Stellantis's faulty "Multi-Displacement System" (MDS) cylinder-deactivation system and "eTorque" mild-hybrid system. Both systems work together to save…”

“I own a 2022 Jeep Wagoneer with the 5.7L HEMI eTorque system. The vehicle has lost all power while being driven on two separate occasions. The first occurred on October 22, 2025, on a major interstate. The second occurred on January 30, 2026, on a state highway. In both cases the engine shut off without warning while the vehicle was in motion, with my wife and four children aboard. Power steering and braking assist were lost. The vehicle locked into Park, and I could not get power to shift into neutral or restart it. The January 30 incident required towing. The vehicle was inspected by a mechanic, who was unable to replicate the problem. Since the second failure, I have observed that system voltage drops rapidly during normal driving on nearly every trip. To avoid another shutdown in traffic, I now monitor voltage and pull over to shut the engine off and restart it once it reaches 12.4V. This takes several efforts each trip to pull over and restart the system. It has produced anxiety in my family about the safety of this vehicle. This is a full-size SUV losing power in highway traffic without warning. It endangers my family and every driver around us. I am…”
