2022 Jeep Wagoneer engine problems

Filed Sep 28, 2026 · Electrical, Engine · AR

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 complaint and advise me regarding any available assistance, escalation options, or known remedies related to this condition. Thank you for your attention to this matter. I look forward to your prompt response.

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 fuel at cruising speeds and stoplights. However, due to the constant cycling of both systems, they contribute to the excessive engine stress and oil pressure fluctuation, which are known for the "WS" Jeep Wagoneer, the "DT" RAM 1500, and the "WL" Grand Cherokee equipped with the 5.7L HEMI eTorque V8. The dealer relayed the issues to Stellantis North America, showing videos and photos of this catastrophic mechanical failure.

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 aware of ODI Preliminary Evaluation PE24018 covering this vehicle and system, and I am submitting this so my incidents are part of that record.

While driving down the road, I came to a stop and the vehicle started flashing every light then would not restart or allow the vehicle to be put into neutral. Initially thought maybe a battery issue despite my new battery being only eight months old replaced the battery and all the electronics started going haywire requiring the vehicle to be towed.

While driving my 2022 Jeep Wagoneer at 40-45 mph on a live public road with my four small children in the vehicle, the vehicle suffered a sudden, catastrophic electronic and powertrain shutdown without warning. The engine completely died, and the vehicle immediately and forcefully engaged the electronic emergency parking brake, bringing the vehicle to an abrupt, unexpected halt in the middle of moving traffic.Once stopped, the vehicle completely refused to crank or restart. The electronic shifter and braking system effectively locked the vehicle in place, leaving me and my four young children dangerously stranded inside a dead vehicle in the middle of a live lane, creating an immediate, life-threatening collision hazard from oncoming traffic. The vehicle had to be physically towed away from the scene to a dealership, where it currently sits awaiting diagnosis.This vehicle has a documented history of prior electronic and dashboard glitches that the manufacturer has failed to permanently resolve under warranty. The sudden loss of propulsion combined with autonomous, unwanted emergency brake activation while in motion represents a severe, un-remedied safety defect that put the lives of my entire family at immediate risk.
