2022 Jeep Wagoneer: sudden loss of power

Filed Oct 1, 2026 · Electrical · AR

My 2022 Jeep Wagoneer has experienced four separate incidents of complete power loss while being operated. During these events, the electrical displays went dark and electrical functions stopped working on the entire vehicle On [XXX], the vehicle lost all power while I was pulling into my garage. It would not release from Park normally and required wheel skates and towing. The dealership replaced the battery, but the symptoms later returned. On [XXX], the vehicle lost all power while traveling approximately 20–30 mph near [XXX] and [XXX] in heavy holiday traffic. I could not reach the shoulder and stopped in a turning lane without a collision. The vehicle required towing. The dealership told me it performed a computer reset and software update. In approximately February 2026, associated with a February 11 service entry, the vehicle again lost power while driving. I was able to restart it and drive to the dealership. My recollection is that I was told another reset/software update was performed, although the online service summary says “Check Battery.” On [XXX], the vehicle lost all power while traveling approximately 35–40 mph on [XXX]. I was able to pull into a service station, restart the vehicle, and deliver it to Chris Crain Chrysler Dodge Jeep Ram in Benton, Arkansas, that day. As of September 30, 2026, the vehicle had remained at the dealership for 33 days without a completed repair communicated to me. A dealership representative, Kim, told me by telephone that technicians had reproduced the failure, suspected an electrical component or connector short, and contacted Jeep engineers. I do not have a confirmed written diagnosis. I am concerned that another unexpected complete power loss in traffic could cause a collision. Similar symptoms have recurred after prior repair efforts, but they all share the same underlying cause. I request review of these incidents as a potential safety defect.

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.

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 the federal safety agency Investigation PE24018 regarding 2022 Jeep Wagoneer 48-volt electrical and power distribution failures.

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 my wife was operating our 2022 Jeep Wagoneer Series III (5.7L HEMI eTorque, ~44,700 miles) at highway speed, the vehicle suffered a sudden and complete electrical power failure. Electric power steering cut out completely while the vehicle was in motion, creating an immediate safety hazard and nearly causing an accident. The vehicle was disabled and required towing. The dealership (Safford Jeep) diagnosed fault code P0B32: catastrophic internal hardware and voltage failure of the 48-volt eTorque Hybrid Battery Pack. The 12-volt battery was also destroyed as a consequence of the 48V pack failure — the 12V charges exclusively via a DC-to-DC converter fed by the 48V loop; when the pack failed, the converter lost power and the 12V battery was starved of charge. NOTE: This incident is consistent with the active the federal safety agency ODI preliminary evaluation of 2022 Jeep Wagoneer and Ram 1500 eTorque electrical failures. FCA/Stellantis has acknowledged these failures are likely caused by an electrical concern. My P0B32 event represents a catastrophic failure of the exact system under investigation, with the additional safety consequence of complete loss of power steering at highway speed. Stellantis Corporate Case #96719164 is open. The vehicle has been repaired (48V battery pack replaced) but Stellantis has declined to address the warranty access barrier created by their diagnostic system architecture. The dealer's equipment required a new 12-volt battery installation before it could communicate with the covered hybrid system — a $645 mandatory prerequisite to accessing a Federal Emissions Warranty repair.

During normal driving in temperatures below approximately 20–27°F, the vehicle began losing electrical charge as indicated by the malfunction indicator light (MIL) and battery warning message. While my wife was attempting to return home, multiple vehicle systems progressively shut down, including electric power steering, ABS, auto-leveling suspension, and lane departure assistance. As she was pulling into our driveway, the vehicle completely shut off, resulting in total loss of propulsion and power steering. The vehicle had to be towed to the dealership. This was the second occurrence of this failure. A third incident occurred the following day under similar temperature conditions. During that event, MIL and battery warnings appeared again during normal driving. She was able to reach our driveway before complete shutdown occurred. On the most recent incident, the following diagnostic trouble codes were present: P0EEC, P1618, P0008, and U0111. These are the same codes that were recorded during the previous two incidents. After the first two failures, Kernersville Dodge stated the issue had been repaired and charged us for the repairs. The same failure condition has now reoccurred. This failure results in sudden loss of propulsion and loss of power steering while driving, creating a significant safety hazard.

The lithium battery failed causing a complete loss of power, power steering, power brakes while driving with 3 small children on board. Battery indicator warning on dash. The dealer expressly stated that the car was safe to drive. Obviously that was incorrect. Thank goodness we were able to safely stop and be towed to the dealer. I escalated to "Jeep Cares" Case number Jeep Wagg Case 95595257and going on 4 weeks and no one can tell me when the battery will be available and that this battery will only last 3 years. If Jeep has no inventory then that is a red flag and the consequences of this failure puts lives at risk
