Jeep Grand Cherokee 4xe loss of power problems

Filed Mar 11, 2025 · Fuel system · TX

The vehicle lights up a red wrench with a lightning bolt through it and then alerts to a "service hybrid electric vehicle system" message. This light stays on from either a few seconds to several minuets before turning off. There is no consistency as to when the warning illuminates. Every time it has come on has been at highway speeds. There is fear that the vehicle is going to lose power and/or propulsion while at a high speed. This feels like a danger to myself, my occupants, and others on the road.

This vehicle has a nonstop history of unresolved electrical issues cause numerous warnings of failed systems, failure to start and randomly going into "Limp mode". It has been to the Jeep service shop 7 times so far. Recently, the vehicle completely shut down and lost all power while driving at speeds higher than 50 mph on 2 separate occasions. On February 2nd 2025 the vehicle lost power on the freeway at 80 mph. I swerved into the left shoulder to prevent an accident. vehicle was towed to Jeep service center, a software upgrade was performed and returned to me as presumed "fixed" by Jeep. On February 25, 2025 the vehicle again lost all power while driving down a highway at 50 mph. Again, forcing me to swerve off the road onto the right shoulder to avoid an accident. Vehicle again was towed to a Jeep service center where it remains.

While driving on the highway at 65mph, the car suddenly lost power in middle of traffic and stopped. I was barely able to park on side of the road and was facing a severe risk of being crashed into! I was able to restart the vehicle after 7min by holding stop start button for long time

While driving on the freeway, the vehicle turned off. No engine, no electric, no headlights. I had to coast to the side during traffic. The mechanic is replacing the OCR module, stating the car thought it was in a collision and turned off. Though obviously it wasn’t. Before which, the screen flashes off from time to time. The car has had loss of power for a moment in the past but never all the way off. This was extremely dangerous and I’m concerned the OCR will not fix the issue. It is with the dealership now.

I started getting random "service hybrid electrical system" warnings. The warning would come up and go away after approximately 5 seconds. On 2/5/25 I was on the highway going about 65mph when this warning light came on and I lost power. I still had power steering and brakes, but no acceleration. I was in the middle lane during rush hour, trying to coast over to the shoulder. Luckily I was able to make it without causing an accident. I put the vehicle in park and was able to restart. This happened a second time, but luckily I had just parked and was idling. Obviously, this is a very scary, dangerous situation for a vehicle to suddenly lose power anytime let alone when on a very busy highway. The vehicle is currently at the Jeep dealer, but I have read that this is a very common problem with the Jeep hybrids and does not sound like Jeep has figured out the root cause.

On February 10, 2025 at approximately 4:45 EST, I was driving approximately 55MPH in the far left lane of a multi-lane highway when I received a notice that my hybrid propulsion system had malfunctioned. Upon receiving the notice, I immediately lost power/propulsion of my vehicle although the warning notice disappeared and the screen made it appear that the vehicle was operating. As I pressed the gas pedal, I noted that there was no power being provided to the powertrain and I had to progressively move to the right to find a safe spot to stop. Upon stopping, the warning re-appeared and informed me to put the car in park and turn it off and restart the vehicle. At the time of failure, the battery had a remaining charge of 10% and 3/4 tank of gas. Upon restart, the vehicle functioned as normal using the gasoline powered engine. The vehicle is available for inspection upon request. My safety was put at risk due to the loss of power in an area where most vehicles were operating near 55 MPH. The computer warning about the malfunction was confusing and it disappeared relatively quickly leading to significant confusion about how to operate the vehicle especially given that the dashboard returned to a normal state. The problem has not yet been reported to a dealer as they were closed for service. There were no warning lamps, messages, or symptoms prior to the failure other than the short warning that appeared at the start of the loss of power and referenced above.

I was driving on a local road going 35-40 mph, when SUV shut off (no power). I maneuvered to the shoulder, and tried to restart, which it did. The hybrid was near the end of the charged battery mode, when this happened. I purchase the Grand Cherokee 4XE (new) in May 2024, and recently had the battery replaced due to a safety recall. This is the first time I lost power while driving. The car has been at the dealer’s for two days, and they have not found the problem. There was no error code, and they could not replicate the loss of power.

On 12/28/24 we dropped the vehicle off for a check engine light issue + the 95B recall fix. It was discharged on 12/31/24. On 1/9/25 the vehicle lost all power while flashing the red wrech lightning bolt symbol. I had to coast to a stop (I had been exiting the interstate) and had to drive into a pile of recently plowed snow to avoid being rear ended. The vehicle put on the parking brake and the engine had shut off. I turned on the engine after a few moments and it worked fine and I was able to drive it straight to the dealership (2 miles away.) They kept the vehicle for 2 days and could not get the issue to happen again, however they said they re-did the 95B recall and seemed confused about it having been done a few weeks prior. Today on 1/15/25 while driving on the interstate at about 65mph the issue happened again and I had to quickly pull off on the shoulder. The dealership told me to record the issue, but that's impossible while trying to steer it with zero power on the interstate. The same lights flashed (red wrench lightning bolt) and it shut down. Upon restarting it worked as expected. I do not feel safe driving it anymore. The dealership cannot find the issue and I don't want my kids in the vehicle on the off chance I cannot get over, or someone is driving offensivly around me. I am in fear of my life for driving this vehicle so much so that I am considering buying a different car today and letting this one sit until my lease is up. There are no other warning lights at this time on my panel. I will be taking the vehicle back to the service department this afternoon.

Event occurred within 2 days and 50 miles of recall 95B service being performed on 2022 Jeep Grand Cherokee 4xe showing passing results. After startup of the vehicle and being placed into 'electric' only drive mode and DRIVE engaged, the vehicle traveled down the driveway approximately 10 feet when the vehicle juddered, the driver display showed an error message "Service Hybrid Electric Vehicle System", a red wrench icon appeared in the dashboard/instrument cluster, and the vehicle automatically switch into 'hybrid' drive mode and started the gasoline motor. The vehicle was turned off, then restarted. Upon restart the error message was not visible and the red wrench icon was gone. Vehicle was then able to be operated in full electric drive mode. My safety was at risk because if the sudden juddering and loss of power occurred at speed on the general roadway instead of in my driveway I could have lost control of the vehicle and crashed. I do not know if this has been reproduced by the dealership but I have heard anecdotally about other 4xe drivers having this same issue immediately after the 95B recall service was performed. The vehicle is scheduled for inspection with a Jeep dealership on 1/21/25
