2025 Jeep Wrangler Powertrain & Transmission Problems

Component/System Failure: The hybrid/electric propulsion system intermittently loses power while driving. Electric output is progressively reduced to approximately 50%, then 25%, and then fully disabled, even when sufficient battery charge remains. The condition appears to involve the hybrid control/electric drive system. The vehicle is available for inspection upon request. What Happened / Safety Risk: The loss of electric propulsion occurs unpredictably during normal operation, including both highway and city driving. The reduction in available power and sudden loss of electric functionality creates a potential safety concern, particularly when driving in traffic or at higher speeds, where reduced or inconsistent propulsion may impact the ability to maintain speed or respond to driving conditions. Additionally, the vehicle is subject to a high-voltage battery recall involving fire risk, which raises concern regarding safe operation and storage of the vehicle. Reproduction / Dealer Confirmation: The issue has been reproduced and confirmed by the dealership (Johnson Auto Plaza, Brighton, CO). The dealership also confirmed that the same issue was reproduced on another Jeep Wrangler 4xe vehicle on their lot. Inspection by Manufacturer / Others: The vehicle has been inspected by the dealership and escalated to Jeep Engineering. The manufacturer has been unable to diagnose the issue due to the absence of diagnostic codes and has not identified a repair. Warning Lamps / Messages / Symptoms: No consistent warning lamps or diagnostic codes are present when the failure occurs. The loss of electric functionality happens without a predictable pattern and without clear diagnostic indicators. Additional Notes: The issue occurs unpredictably under all normal driving conditions, including: Highway driving at speed City driving at low speed Various battery charge levels (low and high) The dealership has suggested possible driver-related causes; UNsupported by car behavior

Subject: Safety Complaint – 2025 Jeep Wrangler 4xe Unexpectedly Shifted Into PARK While in Traffic Vehicle: 2025 Jeep Wrangler 4xe Mileage at Time of Incident: 1300 Date of Incident: [XXX] Location: Ohio I am submitting this complaint to formally report a serious and dangerous safety defect involving my 2025 Jeep Wrangler 4xe. While approaching a red traffic light at normal driving speed, the vehicle suddenly and without any warning shifted itself into PARK. I did not press the park button, and no alerts or warnings were displayed prior to the event. The vehicle abruptly decelerated, leaving me momentarily without power in active traffic. I had to quickly react, restart, and shift back into gear. This incident was completely unexpected, and placed me and others at immediate risk of a rear-end collision. This behavior is unacceptable in a modern vehicle and represents a clear safety hazard, particularly in traffic conditions where sudden loss of propulsion can result in serious injury or death. There were no dashboard warnings, messages, or indications that the vehicle was about to enter PARK. The vehicle was functioning normally immediately before the incident. I am requesting: 1.A full investigation into this incident 2.Written documentation of any known defects, recalls, or software issues related to unintended gear shifts in the Wrangler 4xe 3.A permanent fix, not a temporary reset or software update without explanation 4.Documentation placed in my vehicle service record acknowledging this safety issue I am also submitting this complaint to the National Highway Traffic Safety Administration (NHTSA) due to the severity of the safety risk. This incident has caused me to lose confidence in the safety and reliability of this vehicle, and I expect this matter to be treated with urgency. The vehicle is currently in the shop for the past 4 days with no call explaining what the problem is. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On 10/10/25, my 2025 Jeep received an over-the-air (OTA) software update intended for the Uconnect infotainment system. Following the update, the vehicle experienced a complete powertrain failure. It became undrivable, shut off entirely, and refused to shift out of park. This occurred without warning and posed a serious safety risk, especially had it happened while driving. The issue appears to be related to the hybrid control module, which was affected by the software update. The vehicle displayed multiple warning lights and fault codes (including Service Hybrid Drive System). I had to contact roadside assistance and have the vehicle towed to a dealership. Jeep has since acknowledged the issue and pulled the update, but I am concerned about the potential for permanent damage to the powertrain and the safety implications of such a failure. I am requesting that NHTSA investigate this matter to ensure proper accountability and prevent similar incidents for other owners.

The referenced vehicle "jerks/jolts" while driving. It was doing this when test driven on 7/31/25 and I was told by the salesman that this was normal even though he did not ask any questions about the jerking. On 8/1/25 I picked the vehicle up (leased). Because it had a cracked windshield, I again asked about the jerking and if it had any issues at all, and, again, I was told it was fine and nothing was wrong with it. The Jeep dealer serviced the vehicle x5 between 8/5-9/26/25 and was last in their service department from 9/3-9/26/25. The engine light has never been on and during the different service visits, an alignment was done, the valve cover gasket, oxygen sensor and valve body were replaced. No car accidents have occurred, however, because the "jerking/jolting" continued after the valve body was replaced, a lemon law case was requested and has been accepted.
