2023 Jeep Grand Cherokee 4xe: sudden loss of power

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.

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.

Driving 35 MPH on a back road, no cars coming the opposite direction, the automatic emergency braking system flashed, beeped and slammed my brakes momentarily. Luckily there was no one behind me. I attempted to pull into a parking lot and the entire electrical system went crazy, all warning lights, systems and sensors went off and I lost power steering. Had I been driving during power steering loss it would have been very dangerous. This is the second time this has occurred with the lights and power steering issue (first time for the AEB system issue) and the dealer kept the car 3 weeks to repair it but clearly the problem persists.

The vehicle was newly acquired and was set to run on Electric mode. I was driving on the Highway at highway speed and suddenly without any warning, it lost all power due the what is called "FORM" making the electric engine unavailable. There was a semi truck right behind me which almost hit me since by losing my electric engine I dropped my speed suddenly. I had to pull over and try to figure out what was going on and switch to Hybrid mode. The issue is that #1 this comes without any warning at any moment, making your electric engine absolutely useless and then why do we even have the option of an Electric only engine. #2 we have no control on delaying even for just a few miles this FORM mode to allow us to get to a gas station or to a safe location since the button to switch to Hybrid mode is not located in an easy access while keep your eyes on the Road. #3 I end up in that FORM mode almost every other week now . This FORM is not even something that is communicated by JEEP in their advertisement. You can't find the information about it unless you end up having the issue and look for it. I don't even reach the advertised MPG due to the FORM. I use gas every day regardless so I should not need to be in FORM mode every other week
