2022 JEEP WAGONEER Complaints

Vehicle Information: 2022 Jeep Wagoneer (5.7L V8 eTorque Mild-Hybrid System)Component Affected: Electrical System / Hybrid Propulsion System Defect: My 2022 Jeep Wagoneer continuously experiences sudden engine stalling and unexpected shutdowns while operating in Auto Start-Stop mode. When the vehicle comes to a complete stop at a red light or intersection, the engine shuts off normally to save fuel. However, when I release the brake pedal to accelerate, the vehicle fails to restart automatically. Instead, the vehicle suffers a total loss of power, drops the transmission directly into Park (P), and abruptly engages the emergency parking brake. This creates an immediate, severe safety hazard as it leaves me completely stranded in active traffic and at busy intersections. To get moving again, I am forced to completely cycle the push-button ignition manually. Additionally, the vehicle regularly fails to remote-start, turning itself off immediately due to the electrical fault. A diagnostic scan reveals DTC P0B42 (Hybrid/EV Battery Voltage Sense "B" Circuit Low). This dangerous stalling pattern directly matches the active federal probe under NHTSA Investigation PE24018 regarding 2022 Jeep Wagoneer 48-volt electrical and power distribution failures.

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.

Liftgate Latch Assembly Failure: The vehicle experienced an internal electrical short circuit and hardware failure within the power liftgate latch assembly. This defective latch caused a severe parasitic 12V battery drain that repeatedly rendered the vehicle completely dead, leaving it unexpectedly stranded. The hardware failure also triggered a software error loop that locked the power liftgate into an inoperable mode (3-beep lockout). Replacing the liftgate latch assembly successfully resolved the liftgate operation and eliminated the parasitic drain. Uconnect 5 Software Defects: Independent of the physical liftgate issue, the Uconnect 5 infotainment system (currently running software build U29.42, referencing TSB 08-230-24) exhibits significant software bugs and display stability issues. The primary central screen frequently flickers, displays line artifacts, freezes, and repeatedly drops wireless Apple CarPlay connectivity. Additionally, when shifting the vehicle into reverse, the rear backup camera feed fails to load, displaying only a blank black screen instead of the camera view. This disables primary vehicle setting controls, navigation interfaces, and rearward safety visibility while operating the vehicle.

vehicle lost eng power would not restart had to be towed to dealership they conformed problem

While merging onto the interstate with my wife and kids in the car, the car engine stopped nearly causing a dangerous accident. Got it to a dealership and the etourque system needs a 4200 repair and I believe there is an investigation into this problem with Jeep

The right second row passenger seat in a 2022 Jeep Wagoneer appeared to be pushed fully rearward into its normal seating position and produced an audible/tactile click. No warning lamp or message indicated that the seat was not latched. While traveling approximately 40 to 45 mph, the driver had to brake hard. During braking, the entire right second row seat moved rapidly forward and pinned a child and the child restraint against the front passenger seat. The child struck the side of her head, was evaluated in an emergency department, and was diagnosed with a mild concussion. After the vehicle stopped, the seat was pushed rearward only to free the child. It then latched and is currently available for inspection. The seat has not been tested or operated since. The exact cause is UNKNOWN. Possible causes include incomplete latch engagement, a latch or actuator malfunction, or a failure of the seat position warning system. The vehicle has a prior documented warranty repair involving the opposite second row seat. In October 2024, that seat’s motor could be heard operating but the seat would not release. The dealer diagnosed a weak release motor and replaced two folding seat motor actuators under warranty. The current failure has not yet been reproduced or confirmed by a dealer. The vehicle and seat have not yet been inspected by the manufacturer, police, insurer, or an independent repair facility. Photographs, hospital records, and the prior warranty repair record are available. A case has been opened with Stellantis.

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 on the highway going 70 mph, the vehicle lost all power and shut down engaging the automatic emergency brake system. This is the second time it has happened. Car is currently at dealership awaiting service.
