2022 Jeep Wrangler: engine failure

Filed Jun 27, 2025 · Electrical, Engine · FL

The vehicle experienced multiple serious fuel system failures, including a failed fuel injector and high-pressure fuel pump. After these components were replaced, it was confirmed that fuel was still entering the engine crankcase. At no point did the vehicle trigger a “Check Engine” light, oil dilution warning, low oil pressure alert, or any hybrid/electric powertrain. This represents a critical safety & reliability issue. Fuel dilution of engine oil can: severely degrade lubrication, increase crankcase pressure, and/or lead to internal engine failure or fire The lack of any warning or diagnostic code suggests either: a software calibration issue in the ECM/BCM that failed to detect the problem, a sensor failure, and/or a defect in the onboard diagnostic system itself. This could indicate a broader defect affecting the safety of the 4xe platform and request investigation. This failure delayed necessary service and put both vehicle and occupants at risk.

This vehicle has been towed to the dealership 4 times for ongoing transmission errors and has caused the vehicle to shut off in traffic on 3 separate occasions, putting myself and those around me in immediate danger. The vehicle has actually rolled backwards in traffic on 1 occasion, without giving me the ability to stop it initially because the brakes and gear shift were locked up. The vehicle has also been repaired for a multicylinder engine failure early on as well. The vehicle is now showing issues with the battery wiring and has been repaired several times regarding this as well.

I have taken my 22 Wrangler in 3 times to the dealership to fix the engine overheating, each time it was a different component until they said we need an entire new engine. Safety of us was overheated engine without a warning on the highway going 70+ speeds. I have heard several other stories of 21 and 22 wranglers overheating, I am not sure why a recall hasn't been issued.

Vehicle was being driven at about 10 mph or less in a busy and congested area. left turn was made. There was an immediate loss of braking and steering with this turn. The vehicle engine began to roar and the tachometer went to highest number. Just about all warning lights on the dash were flashing and there was audible beeping as well. The ignition was turned off but all warning lights continued to flash and there were audible beeping. The vehicle had locked itself into an "Auto Park" mode, and it was unable to be driven or placed into gear. The battery was disconnected, allowing the computer to reset. Although the vehicle continued to malfunction, I was able to drive it out of the main traffic and into a parking lot. A wrecker was called, and the vehicle was transported to a local Jeep dealership. The local dealership kept the vehicle for several days, and tested it extensively. They were able to reproduce the loss of steering. They found some erroneous solders on a component, the "Star Connector". It is believed that this may have shorted something in the electrical system. The safety of myself and family and all others in the vicinity of the Jeep 4xe were in grave danger when the initial brake, steering and engine failure occurred. Other people may well have been run over during this event. The problem of loss of steering was reproduced by the Jeep dealership that worked on the 4xe, and they feel that it was corrected by replacing the Star Connector. I have paperwork from the dealership to document the incident. The vehicle is available for inspection and I currently have to drive it, although I have loss of conficence and feel afraid to drive it.
