2024 Jeep Wagoneer S

The high-voltage propulsion system and Battery Pack Control Module (BPCM) failed. The vehicle suffered an abrupt drop in power, overriding driver input and forcing it into "turtle mode." The vehicle is currently un-diagnosed and available for inspection at the Jeep dealership. My safety and the safety of others were put at immediate risk. The vehicle suffered a sudden loss of acceleration in live traffic. This abrupt drop in speed creates a severe hazard for rear-end collisions, as the vehicle could not maintain traffic speeds or accelerate out of danger. The vehicle was towed to an authorized Jeep dealership on August 10th. The dealer missed multiple diagnostic commitments (August 14th and August 24th) and has failed to diagnose or repair the issue for over 16 days. No formal inspections have been completed by the manufacturer, police, or insurance representatives since intake. The vehicle experienced multiple power drops into turtle mode on multiple dates with dashboard warning lamps illuminated. This mirrors known software issues on this platform detailed in Stellantis TSB 08-022-25 REV. B.

My 2024 Jeep Wagoneer S has experienced repeated electrical and drivability failures. Most recently, while driving at approximately 16,500 miles, the vehicle displayed “Service Electric Vehicle System” followed by “Stop Safely – Vehicle Will Shut Off Soon.” The warning appeared while the vehicle was in motion, creating concern that the vehicle could lose propulsion or shut down unexpectedly in traffic. This was not the first serious incident. On a prior occasion, the vehicle made loud clicking and clacking noises and later became disabled in downtown Berwick, Maine. During that incident, the vehicle would not shut off and would not shift into Park, leaving me stranded and unable to secure or operate the vehicle normally. These repeated failures involve the vehicle’s electric drive/electrical system, ability to remain operational, ability to shut down, and ability to engage Park. I am concerned that these conditions could create a crash, rollaway, or roadside-stranding risk depending on when and where the failure occurs. Warning messages have included “Service Electric Vehicle System” and “Stop Safely – Vehicle Will Shut Off Soon.” I have photographs documenting the warnings. The vehicle and its systems are available for inspection upon request. The vehicle has previously been presented for service related to ongoing problems. The exact underlying cause of these repeated failures is currently UNKNOWN. I am reporting the issue because the problems have occurred more than once and appear to represent an unresolved electrical or propulsion-system defect.

On XXX I was unable to turn off my vehicle and could not shift it into any gear. The vehicle had to be towed to Sames Bastrop Chrysler Dodge Jeep Ram ([XXX]) for repair, RO #XXX. The dealer's diagnosis noted the high-voltage battery at 3 percent charge and referenced TSB 08-128-25. The correction involved disconnecting the 12V battery and reprogramming multiple control modules (BPCM, MCPA, MCPB, EVCU, IDCM). No crash or injury occurred.

The contact owns a 2024 Jeep Wagoneer S. The contact stated that while the vehicle was parked, the vehicle unexpectedly shifted to reverse(R) and rolled backwards unintendedly at approximately 10 MPH. The brake pedal was pumped several times to stop the vehicle. The contact stated that several unknown warning lights were illuminated, and the messages “Collision Protection OFF”, “Service ABS” and “Traction Control OFF” were displayed during the failure. The dealer was contacted; however, the vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 31,057.

EV stalled, would not turn off or on, refusing to go into gear (Park, Drive, Reverse or Neutral) and the emergency brake automatically engaged. Foot pedals were unresponsive and wheels locked. Pedestrian safety chime played continuously even though the vehicle was not in gear. Park and Drive did not light up on the gear indicator and all options glowed red. Various error codes displayed one after the other on the driver's information screen. Vehicle had to be towed on a flatbed. Vehicle remained in that condition for at least four days. Attempts to reset the vehicle using door locking and key removal and also disconnecting the negative terminal on the 12v battery were unsuccessful. The vehicle would not turn off or on and would not go into gear. The vehicle was towed to a dealership where it still cannot turn off.

At 2,000 miles car experiences an issue when going from drive to reverse the car issued warning that transmission needs to be serviced, wouldn’t go into any gear and wouldn’t turn off. Had to be dragged into flatbed truck and taken to dealer. At 3,000 miles had to stop in road due to medical helicopter and road being closed. When road opened up went to put car into drive. Same errors as before (can’t get in gear, warning lights and won’t turn off) and car had to be dragged onto a flat bed tow truck. Fire department initiated the tow due to safety issues of being in dangerous location. After a week at dealer was told it was ready to pickup. Then told to see a mechanic there who would show me what to do next time this happened. Involved unhooking 12v battery and pulling some fuses. Informed issue wasn’t fixed just a work around was done. I talked to service manager and was informed this is a known issue and factory is working on a repair. The car isn’t safe breaking down twice while driving on public roads and not being able to turn off. Note: in both cases the car wouldn’t turn off for days even while parked at dealer lot.

I was stopped at a red light on a busy road. When it turned green and i accelerated the car would not move. It jerked and the dash lit up lioke a Christmas tree. A big red turtle came up on the dash and I was able to move but only 5-7 miles per hour. I drove the 8 -9 mile home at only 7 miles an hour while being honked at and near misses from the heavy trraffic. The vehiocle was towed to the dealership and I am being told that the manufacturer is aware of the problem but there is no current fix. They may actually try to return the vcehicle to me as is, but I do not feel safe driving it. On a side note, tis is the 5th time the vehile has been in the shop in the 6 months we have owned it.
