While driving a vehicle swerved into my lane, to avoid hitting them I tapped my brakes, upon tapping my breaks the Jeep lost propulsion and it felt as though my brakes lost power as well. I had to coast into a parking lot where I didn’t even make it to a spot and had to be towed to the dealer. The Jeep would no longer start and gave a “service charging system” message. Upon inspection the dealer stated that Chrysler immediately shipped a power inverter module (pim) upon my Jeep being entered into the system. Since my issue, I have seen 3 other 4XE Jeeps pulled over and broken down in precarious positions. This is what prompted me to file this report, as I believe this may be an issue related to other 4XE Jeeps and if this is the case, it is only a matter of time before an accident that causes loss of life because of how severe and sudden the issue is. Thanks for looking out for our well being and everything y’all do at the federal safety agency.

On 5/23 less than 24 hours after delivery with 76 miles on the ODO, I got a (CEL) and numerous errors (service hybrid electrical vehicle system, service 4wheel drive system, vehicle charge fault with a red charge cord light indicator). Vehicle was returned to dealer on Monday morning with notice of issues. They diagnosed the vehicle for 1 day and returned it to me to continue to drive while they ordered parts. Vehicle was diagnosed with a P0AA6-00 “Hybrid Battery Voltage System Isolation Fault.” Dealer stated vehicle was safe to drive and would contact when parts were received. On 6/08 vehicle was returned to service for incoming parts at 575 miles. Dealer stated FCA advised them to replace the Indicator lamp module but did not correct the issue and they could not return the vehicle to me as they stated "FCA said vehicle can not be placed back on road as it may catch fire or explode". Vehicle has been at the dealer with no return since 6/8/2021. They have changed 1 indicator lamp module, 2 battery heater/chiller modules, 3 PHEV main wire harnesses and have requested a 4th as they have not been able to make the previous 3 work/function. Vehicle has now been down 7months with now successful repair and parts not available until 1/02/2022 at the earliest. And vehicle now sits with 17 unresolved trouble codes.

I was driving normally along a busy road at 40mph. Suddenly, the car stalled and I could not accelerate. I coasted until it completely stopped in the middle of a busy road. I was unable to move the car, and instead had to put the car in park and turn off the engine. The "D" light on the gear shifter was blinking, and then the battery on the car went from 55% charge down to 47% charge. A red lightning bolt emergency sign came on but then went off immediately after. With the car off in the middle of the road, I restarted it hoping for the best. Luckily, it did restart fine and I could continue driving. However, I have heard on Jeep 4xe forums that this is an issue with many other owners, some even happening on the interstates. I am now too afraid to drive this car with my child or for long distances, because this issue was completely spontaneous and unpredictable. I took it to the dealer to be serviced, but they are unsure what is going on. And as a side note, this is a brand new car (2021 year) with 105 miles. I only had it for FIVE days before this happened. Prior to this incident I also noticed that the charge would not hold very long at all - for example, driving it today 3.4 miles from one point to the dealer, the charge went from 47% to 17% - this should not be normal. Overall this issue is unacceptable and this needs to be addressed immediately before people die. Thanks for your consideration.

I left my daughters house with my jeep wrangler and as I shifted into forward gear there was no power on my wrangler 4XE hybrid. I move the vehicle to the side of the road and towed it to the dealers. After a little over two weeks they got it repaired. After that I have read reports of this kind of thing happening in traffic. When I lost power the engine light and stability control light came on. It is now repaired but I’m having second thoughts about the safety of the vehicle since I sometimes transport my grandchildren in the vehicle.

The two main wire harnesses are faulty. It would not charge or hold a charge. Driving it was dangerous and would stop drastically at any given random moment. A jerking motion would occur while driving. Lights on dash would come on, engine, charging fault station. Charging fault. And lightening bolt warning signs. Sometimes it would say don’t drive call for assistance. The dealership has had my vehicle since June 4 2021. The parts I’m told won’t be available until end of January 2022. I purchased the jeep on April 30th 2021. It’s very scary when you’re on the road, w my family and it decides to lock up or sounds like the transmission is falling from the under carriage. Luckily we weren’t rear ended or pushed through an intersection.

While towing a <3000 lb. trailer up a long grade (2.5 to 3 miles) on the interstate at the posted speed, warning messages were displayed on the dashboard approximately 2/3 of the way up the hill. “Service Electronic Throttle Control”, and Check Engine light displayed while the vehicle speed dropped dramatically from 70 mph to approximately 35. This same error occurred every time I tried ascending a long grade with the trailer (under load). Initially reduced speeds ( below the posted limit) did not change the outcome. Trying to use the optional manual shifting, did not change the outcome. Recreated initial problem following 1st dealership service for the events.

The engine caught on fire after a short drive. The fire burned the entire top of the rear of the engine and completely through the wiring harness before I could extinguish it with a fire extinguisher and water. The fire appears to have started at the top rear of the engine where the fuel line enters the intake. The manufacturer, Stellantis, hired a special investigator from EAA/Bosch to look at it, and he agrees that it is similar to fires in similar engines that were recalled in October 2020, the federal safety agency Campaign number 21V‑665. Stellantis has not responded to repeated requests for resolution.

Charging Fault Error came on as my wife was driving home when her 2021 Jeep Wrangler 4XE suddenly shut off and came to a immediate halt. She was barely able to prevent a major accident, which could've caused serious injury to herself and others on the road. Vehicle would not restart and was not even able to put the vehicle in neutral to push out of harm's way. The moment it happened I received a message on my Jeep UConnect app that a Charging Fault Error occurred. I didn't know what this meant, but about 60 seconds later my wife called me in distress and told me what happened. She was terrified couldn't even drive the rest of the way home and had to stand in 100F heat for an hour waiting for a tow truck. Result: The Jeep Wrangler 4XE is still in the shop (it's been in the dealership for over 3 weeks now, and we've owned it for 3 months and 3500 miles. They have no diagnosis and say they are still ordering parts. Asked 2x to speak with upper management at FCA and was told someone would call in 24 hours, it' been over 72 hours now. Included file of Jeep case number and Jeep 4XE forum with multiple chats on this same issue.

As I approached a stop sign while braking, the Jeep seized up, shut off, and gave the Electronic Stability Control warning. I attempted to restart and it didn’t start or get out of park. It then gave Blind Spot Monitoring System error and Service Charging System error. I’m grateful that I was at a stop sign unlike some of the other reports of this issue that were on the highway. It was quite a jolt when the vehicle seized. The vehicle has been at the dealership since 8/24. It was thought the hybrid battery needed replacement. A new one gave the same errors to the service team. The vehicle remains with the service department awaiting another battery.

While driving on 131 northbound just before the Saginaw croton exit my Jeep lost power I was in the left lane had to merge across to the right to exit and all the lights were on noting charging system needs service I got off highway onto ramp and coasted to side of ramp and realized it was not even on anymore. I immediately shut it off checked my uconnect app for a service warning and it said charging system failure all the lights on the dash were alerting me until it shut down I sat for a bit and tried to start it and it did but was jerky when attempting to drive. I switched to esave and the engine kicked in but was also doggy. I had 60% battery so I’m not sure what happened. I attempted to plug in when I got home and it blew breakers anywhere I attempted to plug it in and made a very loud pop! I didn’t try it anymore at home as it scared me. Contacted the dealer and two weeks later it’s at the shop. They have no idea what is going on - it’s acting up but now doesn’t even put the info into the log according to my service technician at the dealer. They are waiting on Chrysler engineers to get back to them with what to do.

The car flashed a red icon and displayed a message saying power was lost and telling us to pull over safely and put the car on park. We were in the middle lane on the New Jersey Turnpike and people were driving around us at 80mph, and the car would not accelerate. We were able to pull over and restart the car and it worked as if nothing happened. I got an email on the UConnect system saying there was a charging issue, and then a second email saying I should get the car serviced. I took it to the dealership this morning and am waiting on a diagnosis.

While driving the Jeep on the freeway, it shut off out of nowhere and came to a very quick halt. It nearly caused a major accident on the freeway. A few moments after the Jeep encountered this issue and shut off, I received a message on mu UConnect app saying that there was a Charging Fault Error. The incident has been reported multiple times online in Jeep forums for the new 2021 Jeep 4xe. Many people have reported that the Jeep shut off while driving at high speeds on the freeway, and the vehicle comes to a sudden and dangerous stop. This is what happened to me.

This vehicle is a plug-in hybrid Jeep Wrangler. On July 31, 2021 while returning home from vacation and driving at highway speeds (65mph +/-), the powertrain of the vehicle completely failed. The screen flashed that there was an electrical system malfunction and to pull over. The vehicle was very difficult to control as I had to travel across three lanes of high-speed traffic to get to an exit ramp. Fortunately, we made it safely to the exit ramp, where the vehicle completely shut down. This was the second time this happened. While driving to vacation on July 22, 2021, a similar incident occurred. The first incident, however, was not a complete failure. The vehicle's screen flashed that there was an electrical problem, but the vehicle did not completely stall. After pulling over, the vehicle restarted. At that time, I scheduled an appointment with the Jeep dealership to investigate the issue. That appointment was scheduled for August 1, 2021 (the day after the catastrophic failure).

I was driving vehicle on HWY 610 in Houston, Texas at approximately 55-60 MPH. Suddenly, vehicle simply stopped working in the middle of driving. Everything on my dash was reading zero. Car were swearing to avoid hitting me. I also had a baby in the backseat of my vehicle. Suddenly, the dash started to read place car in park, Service Charging System. The P at my gear shift was flashing rapidly. I was able to slowly and dangerously coast to the emergency lane. Where I was able to turn the vehicle off. This is a very dangerous situation. At this point, Jeep has no idea what the problem is an this is very frustrating.

I was driving at night on a 4-lane highway at approximately 55 mph southbound in the left lane. My hybrid vehicle had less than 1% of battery power and was running using the gas engine. With no warning the vehicle suddenly experienced a sudden deceleration to less than 10 mph then a warning light came on stating "service charging system- place vehicle in P and start engine. Fortunately there were no vehicles in close proximity either in front, behind, or in the lane to my right, so I was able to make it over to the shoulder before it came to a complete stop. At that point I received an alert from my UCONNECT app that stated "Your 2021 Jeep Wrangler Unlimited was unable to charge." It also stated to "Get service immediately." I placed the vehicle in park and attempted to start the engine with no response. I repeated the procedure and the engine started after which I was able to drive home. I had the vehicle towed to the dealer the next morning where, after two days, the dealer returned the vehicle and told me they could find nothing wrong. no codes in the computer, and no information from Jeep on any similar problems, despite getting the aforementioned alert received from the UCONNECT app. My main concern is that this type failure, the sudden engine failure/deceleration with no warning either inside or outside (brake lights), especially at night, can easily result an accident. I was very fortunate that I was on a highway with other cars near me. A crowded street, highway, or freeway would be a totally different story.

The vehicle was taken to another dealer where it was partially diagnosed that the Transmission Control Module was disabled. The vehicle was not repaired. The manufacturer was notified of the failure and provided a case number. The approximate failure mileage was 940.

The actual malfunctioning issue is UNKNOWN. However, my best explanation is as follows: While driving my new 2021 Jeep Wrangler Rubicon (which only has 1400 miles), on the highway at roughly 70 miles per hour and going up a hill, the vehicle felt as if it were trying to up-shift a gear but then immediately down-shift a gear. This up-shift and down-shift feeling continued in quick repetition over and over in a violent shaking manner that thrust the entire vehicle forwards and backwards as long as I continued the acceleration up the hill. Letting off the accelerator seemed to end the violent shaking. I pulled over on to the side of the highway to stop, and turned off the Jeep since the check engine light came on. I waited about five minutes and started up the Jeep again. The check engine light was still on, though. Any acceleration at any speed now causes the Jeep to violently thrust forwards and backwards like I experienced on the highway. I tried to get Jeep Roadside to tow the Jeep to a dealership, but learned how worthless this Jeep Roadside program truly was. Several days after this incident, and I still do not have my Jeep at a dealership for repairs, nor do I have a rental. Jeep Roadside refuses to tow my Jeep to a dealership that has a rental, and I cannot afford to pay the towing fee's to get to a dealership with a rental. The nearest dealerships tell me they are six to eight weeks out on loaner vehicles. I'm too worried to try and driving my Jeep the distance to reach a dealership with a rental, cause it is way too unsafe to operate this Jeep with the violent shaking. I'm curious if anyone else is having this same issue, or knows more.

A charging system error caused engine to shut down. I was driving down the road at about 30-40 mph and the vehicle just shut down. I was stopped in the right lane of traffic. A red plug appeared on the instrument panel. The vehicle started back up after several attempts to restart it. The red plug disappeared. I was able to drive the rest of the way home with no issues (about 1 mile). When the vehicle stopped it was in electric mode, had about 50% battery left, and had slightly less than a quarter tank of gas. I called dealer and made a service appointment for today. The vehicle was at the service department for about 3 weeks previously for the service light being on. We picked up the vehicle 2 weeks ago and the issue was not resolved. We had been texting with the service advisor about it while it was there and as soon as we picked it up and noticed the service light was still on he quit responding to us and would not get back with us.
