Mileage when the problem started

Owner reports

Selected complaints filed with NHTSA by 2024 Jeep Wrangler 4xe owners, lightly cleaned up (personal details are redacted by NHTSA).

The contact owns a 2024 Jeep Wrangler. The contact stated that while driving at an undisclosed speed, the check engine light illuminated. After restarting the vehicle, the vehicle returned to normal functionality, but the failure became a regular occurrence. The vehicle was taken to the dealer, who diagnosed a failure with the hybrid propulsion system generator. The vehicle was not repaired. The manufacturer was notified of the failure but did not assist. The failure mileage was 3,000.

Driving along with traffic, in the middle lane of a 5 lane highway, a red turtle light suddenly appeared on my dash and my car instantly starting losing speed and acceleration at a very quick rate. On the middle of the dash my screen read "Push Break and Push Button to Start" (which it usually says when I get into my car to start it, but my car was still on and running). I quickly put my hazards on and was able to safely, with very little time, pull off the road to the shoulder as fast as I could. I put my car in park and then turned it off after examining the dash to see if any other lights were on. Nothing new had appeared and the turtle light was gone. I started my car up again, went to put it in Drive, but I could not get the vehicle out of Park. My shifter would not budge. Several attempts turning the vehicle off and back on and still could not get the vehicle out of park. …

Now on Sunday August 11th at 6:08pm driving home from store with no charge on jeep at all, not in hybrid only gas, the jeep died in the middle of the road, it abruptly stopped with no warning, my body jerked forward and when I pushed down gas pedal there was nothing. There was no type of warning before this happened, no light warning on dash, no beeping NO WARNING. Thankfully the car behind me went around me and thankfully there was enough distance between us. I was on a back road thankfully right near an entrance of a park. After putting it into park is when it started binging at me and beeping and warning lights, service charging system light came on, check engine light. I tried turning it off and back on which I had power like my radio and lights on dash the whole time. I could not get car to go into neutral, I even turned off got out closed door and then tried again. …

On [redacted], my wife was driving down the highway and vehicle started to "buck" and almost stalled out. Check engine light came. She was able to make it to the dealer. Dealer ran the diagnostics and received the P0032, P0171, P2097 and P0300 codes. The dealer found the attached document with basically no repair available. We contacted Jeep customer service and were told that it needs a software update, however, they did not know when it would be available. I was not satisfied with that answer and the case was transferred to Jeep retention. In the meantime, we picked up our Jeep and was advised by the service advisor that this is a known issue and advised us to keep the Star publication in the Jeep so if/when it happens again, they will know what to do. This isn't something we can fix since resetting the fuel system requires their equipment. …

We purchased the vehicle on March 23, 2024. A few days later, a couple of dozen miles on it, the vehicle started to constantly show the following message on the dashboard 'Service Hybrid Electric Vehicle System'. We brought it to the dealership based on their earlies availability on April 17, 2024. They told us there's nothing wrong with the vehicle and it's safe to park inside our garage and we needed to wait for the 'harness' to arrive and be replaced. Finally on May 10th, 2024 the harness arrived and we brought the vehicle back to the dealership to perform the replacement. The vehicle has been in that dealership ever since and this past tuesday, June 18th, 2024 we were informed that the problem is now worse after attempting to repair it for about 40 days and that Jeep/Stellantis adviced the dealership to park the vehicle outside as it's not safe to park it inside anymore. …

1. This vehicle has shut itself off three separate times since Tuesday, 29 January. This happens when using the "E-save" system;i.e. mainly the gasoline engine and the engine has not yet reached full operating temperature. It has happened only while stopped at a traffic light. I will contact my dealership Monday, 5 February. The vehicle is available for inspection. 2. Being stopped at a traffic light with a stalled vehicle immediately irritates the drivers behind or worse a driver approaching from behind with a green light. I could be rear ended. 3. I'm contacting the dealership Monday, 5 February. 4.No. 5.The "Service transmission" alert annunciates. All other normal indicators are still showing the radio continues to play, the turn signals function, etc. 6.The transmission must be placed into Park and the ignition switch shut off. …

I had just left my home and got up to about 20-25 MPH when my Jeep Wrangler Willy's 4XE suddenly and abruptly came to a full stop causing the tires to lock up as well and screech to a stop then it shut down and I had to restart it. It jolted my upper body and head forward and could've been much more dangerous if I were on a busy road or if anyone were driving behind me. I took it to my local dealership and they were able to recreate the issue after driving it and it shut off just as it did for me. They brought it in and seem to have primarily done some software update but didn't express much confidence in the repair. They just said there were no DCT's but there was some software updates and that should fix it. They also claimed there were no recalls present on the vehicle which is even more scary. …

When coming to a stop light, vehicle stopped and shut off completely. It would stop for 3-5 minutes in order to be able to restart. This occurrence has happened no less than 6 times since purchase of vehicle (approximately 1 week old). Currently Jeep only has 426 miles. Very concerned about the safety. Luckily the automatic shut off has only happened when at a stop light. No this is not the engine shutting off and restarting after the gas is depressed. The Jeep simply will not move and you have to try and restart multiple, multiple times in order to drive it again. It will take anywhere between 3-5 minutes. Please see link below: [redacted]

Service charging system light came on, and the Jeep made a metallic rattle under the hood, and I went to a dealership who said they don't know much about them and could do anything went to two other dealerships who did not have technicians in that day to see it with a Ford dealership who said that they didn't have time and they would get to it due to four weeks I have 150 I've got two other dealerships because I didn't buy it there. No one will help me today and I can't get anyone at the dealership. I bought it AT to call me back and I don't know what to.

My 2024 Jeep with low mileage has had 5 issues of the vehicle shutting off while driving and not wanting to start after the unexpected shutdown. The dealership is telling me there is no issue. Given the low mileage and the fact that it has happened 5 times, I'm scared to drive it. It's a huge safety issue. Twice, it happened while driving in traffic, and I was not able to restart the vehicle. I'm lucky I wasn't rear-ended. If this engine stop happens while on the highway, it could be fatal.
