2023 Jeep Grand Cherokee: check engine light

Filed Nov 3, 2026 · Electrical, Fuel system · CA

I am filing an urgent safety complaint regarding my 2023 Jeep Grand Cherokee 4xe Plug-in Hybrid. During inspection, the mechanic discovered that the electrical connector and wiring associated with the fuel pump were burned and melted inside the gasoline fuel tank. The entire fuel pump assembly was subsequently replaced. Before the failure was discovered, the dashboard indicated approximately 110 kilometers of remaining gasoline driving range, but the mechanic found the fuel tank completely empty. The vehicle also experienced engine vibration and an illuminated check engine warning light. The mechanic suggested that operating without gasoline may have damaged the fuel pump. However, the exact cause of the electrical overheating and melted wiring has not been established. I am extremely concerned about the potential fire hazard associated with electrical damage inside the gasoline tank. I request that the federal safety agency investigate the cause of this failure, the accuracy of the fuel level indication, and whether other Jeep Grand Cherokee 4xe vehicles may be affected.

I turned the vehicle on and put it in reverse. The check engine light came on and it would not exceed 2mph. I hoped it was a short error but when switching to drive it also would not exceed 2mph. I immediately parked it and called a tow truck. Upon the tow arrival the vehicle would not longer change gears and showed both a check engine light and a service charging system warning. The emergency release to change the vehicle from park to neutral had to be used. It was pulled onto the tow truck and has been 6 days at the dealer with no remedy. The dealer escalated to Stellantis for additional assistance in possible repair options.

This is the 2nd time we have received notice of fire hazard for this make/model. The dealership is aware of the problems. check engine light stays on and nobody can figure out why. I cannot charge my car, park near anyone/anything, and constant fear of my car setting fire while driving it.

Monday, November 3rd, 2025 In electric mode - I drove the vehicle forward out of a parking spot. The vehicle made three very large lurches over a 200 foot length of parking lot, enough to bang drivers and passengers heads hard against the head rests each with a loud clunk. Within seconds after the third lurch, the car went into gas/oil refresh mode (which transitions the vehicle from electric mode to gas mode). At that point the accelerator became unresponsive with RPMs hovering just over 1000. After multiple successive press, hold and releases of the accelerator, I took my foot off thinking I had lost all power and was preparing to shut the vehicle off. Before I could, the car began accelerating quickly forward without my foot on the accelerator. This lasted for 1 - 2 seconds before the car stopped accelerating and I was able to use the brakes to stop it. Had this not been late evening (9:45p EST) - the parking lot would have been full of pedestrians and other vehicles which would have caused a collision with other vehicles, or worse caused me to strike a pedestrian. I had no control over the vehicle. I put the vehicle in park and shut it down. After a minute, I restarted the vehicle and brought it home. The check engine light has been lit since. At this time (Monday, November 10th), the vehicle is still at the dealership (brought in Wednesday, November 5th) being investigated for this as well as the transmission (?) issue that was causing the lurching described.

My wife was on the phone with me when she stated the car was reving really high and sounded like it was going to blow up how loud it was. she was driving at about 25-30 mph when the car suddenly jerked and shut off completely, the battery light turned on and the check engine light flashed before it shut off. she was able to brake and roll to the side of the road. I had instructed her to keep her foot on the break since it was not letting her shift to park. We stayed on the phone as i contacted jeep directly and get a hold of a rep she said she was able to put it in park and she tried to turn the car on and she was able to turn it on after 10 min. She drove with the hazards on to my daughters school and dropped her off i told her park the car and don't use it until i get home. I got home on 10/26/2025 and the light was off i made an appointment with jeep for that week 10/31 and they stated they were unable to find anything in the computer for the issue that had occurred instead they saw a issue with my heating and it was pump. i have a case open with jeep and they have yet to return my call after a week of non stop calling, i emailed stelantis but they stated they cant assist has to be jeep directly. i would love some help with this as the car has been to the dealership three time for multiple issues and recalls that they stated they did and still show are not done. i have a schduled appointment for the 68c but there is no remedy yet.

I am writing to express my serious concerns regarding the safety of my Jeep. My vehicle has been to the Jeep dealership approximately five times for the recurring Service Hybrid System Error. Most recently, in August 2025, I received this error again along with a check engine light. Each time this error occurs, I notice that my Jeep drives differently, which raises concerns about its reliability and safety. At present, my Jeep has been at the dealership for approximately 25 days. The dealership has indicated that the issue is related to the 73C code. Despite repeated visits, the problem has not been permanently resolved. I am very concerned about my own safety, as well as the safety of others on the road, particularly because I have been informed that my Jeep is part of the 1% recall group. The ongoing malfunction makes me uneasy about driving the vehicle, and I strongly believe this presents a potential hazard. I respectfully request urgent attention to this matter and a clear resolution to ensure the vehicle is safe to operate.

This vehicle continues to have electrical issues which effects the drivability. For the current service visit, the vehicle was taken in due to “shut down” or “shudder off” as if the car had completely been downshifted and lost power while in full drive mode causing a driving interruption. This driving interruption causes a concern for safety. As of today, the vehicle has been in the service department for 56 days. Red wrench appears each time with "Service Hybrid System", check engine light. Discussions with service department: "No definitive fix" ..•B273C-00 Meaning: (one of the codes) The code specifically points to an issue with the digital crash input, meaning the vehicle's computer is detecting a "crash" event, even when one hasn't occurred. •4xe Specific: This code is frequently seen on Jeep 4xe models, likely due to the complexity of the hybrid system and its interaction with the ORC.

In February I had the 95b recall completed and a short time afterwards started getting a service hybrid vehicle system light and even a check engine light at one point. One of those instances with the service hybrid vehicle system light my car just turned off while I was driving it with my children in the back seat and cars behind me. I lost all control of the steering and vehicles power except it switched to the accessory. I tried to restart but it would not. I had to come to a complete stop, place in park, turn off the accessory and then restart the vehicle. The vehicle was seen promptly following the incident where I was told to drive it on esave and they would try ordering a part that could possibly be a fix. While waiting for the part the vehicle was seen at another dealership that recommended not replacing that part that there was no issue with the vehicle and to drive it on e save or make sure the battery had a charge while driving in hybrid mode. Which is not a solution. Since then I have had several instances of the service hybrid vehicle system warning lights and that includes while driving it on e save which is gas only. Unfortunately the warning comes and goes quickly while driving so it’s not always easy to take a photo while driving although I do have a few to attach.
