The brake force will jump suddenly and fall back when the brake pedal is even maintained at a constant level while the vehicle is being braked to a stop or decelerating. This malfunctioning will lead to imprecise control of the distance to the front vehicle. Engine Wobbling when it is fully stopped with "D" gear engaged, especially when the transmission temperature comes up after a few hours of driving. It can be clearly felt that the entire vehicle is bouncing with the engine. Engine misfires when crawling after a cold start. Engine speed will fall suddenly and then back up. The vehicle will shake badly, which can cause improper reaction and improper operation of the vehicle speed. The passenger seat squeezes the center console on the right side and the plastic panel comes off, which exposes a sharp edge to the passenger's lower body. …

Last week I was driving 70MPH on the highway when suddenly I got the red wrench icon with the message "Service Hybrid Electrical System" on the dashboard. After about 7 seconds I then got a "Put foot on brake and press start" message on the screen - while still going 70MPH on the highway. At that point the car died. I had no power - the accelerator pedal did nothing. Luckily, I was able to pull over to the shoulder and stop. Then I did what it said and pressed the brake + start button. The car came back to life, but I didn't have the full hybrid system - I only had gas - the car was not using any electrical power as the battery level remained constant and did not drop as I drove. I continued for another 20 minutes where I stopped for lunch. When I returned to the car it started up normally and continued to run normally after that. …

I leased a 2022 Jeep Grand Cherokee 4xe. The main failure involves the hybrid electrical system, which repeatedly malfunctions. The most serious issue is that the vehicle will suddenly stall while driving, without warning, leaving me and my children stranded in the middle of traffic. This creates an extreme safety risk, as it has happened in intersections and nearly caused accidents with other vehicles, including a semi-truck. The problem has been reproduced and confirmed multiple times by the dealership. Despite numerous service visits, no permanent fix has been provided. FCA/Stellantis representatives have acknowledged there is not yet a repair for this ongoing defect. The vehicle has also failed to charge on several occasions, displaying "Service Charging System" and "Service Hybrid Electrical System" warnings. …

This vehicle has had multiple recalls. Anytime that I call in to get serviced. I receive one of these responses from their service department: they can't replicate the issue, if the lights that came on are no longer on they cannot tell what the problem was, or they fixed it. I've had multiple calls and service request with the dealership as well with Stalantas and Chrysler capital. I have pictures of different lights that go off in the dashboard whether it's the hybrid service whether it's engine hot, whether it's the driver assist not working, "vehicle ready to drive"while it's been driving a while, other issues that I've had regarding the components in the vehicle the AC and heat not working properly where you can have it on heat and it doesn't heat anything or you can have it on AC and it doesn't cool anything. And then it fixes itself and it starts to work again a few days later. …

I am submitting a safety complaint regarding my 2022 Jeep Grand Cherokee 4xe, which experienced a serious mechanical failure on [redacted], at approximately [redacted] CDT in Detroit Lakes, MN. While exiting a ZIPS Car Wash at low speed, my vehicle experienced a sudden and complete loss of power and/or propulsion. I believe the engine shut down without warning, and the vehicle would not respond to throttle input or move forward. I attempted to restart the vehicle, but it remained unresponsive for several seconds. During this time, another vehicle behind me was unable to stop in time and rear-ended my Jeep, causing damage to the rear of the vehicle and my vehicle. …

The vehicle experienced repeated propulsion loss and powertrain malfunction while driving, creating a serious safety risk. This defect has now been formally acknowledged by FCA/Stellantis through NHTSA Recall 25V576 (filed on September 4, 2025). Prior to the recall, I raised these safety concerns through the NCDS arbitration program, but my case was closed despite documentation of the defect. The arbitration program stated the matter was "resolved," even though I had rejected the arbitrator's decision and the case was procedurally closed without binding resolution. After the recall was issued, I requested that my case be reopened under NCDS Rule 20, which allows refiling when new or material evidence is presented. That request was denied, leaving me without a remedy despite the existence of an active recall for the exact defect I had reported. The safety issue remains ongoing. …

Was driving on a crowded interstate highway that runs through Denver when my 2022 Jeep Grand Cherokee 4xe suddenly turned off. Luckily, there were no cars in the adjacent lane and I had enough forward momentum to get across that lane and onto the shoulder of the road. There were no warning lights or alarm sounds, the engine just turned off. After reaching the shoulder, I restarted the car and could drive it to a dealership. It is currently at the Jeep dealership undergoing diagnostics. This was an unbelievably dangerous event that could have resulted in a multiple car pile up with injuries or deaths (most likely mine or my wife's) since we were in such heavy traffic at a speed of about 70 mph. We are the sole owners of the vehicle and have kept up to date on all recalls of which there have been several. …

Yesterday, I had been traveling on the turnpike and was attempting to merge back on from a rest area when the Jeep entered "turtle" or "limp" mode without warning, indicating a failure of the hybrid system. The speed dropped instantly to 2mph and the engine kept revving, generating dark exhaust and a concerning smell (hot, different from regular vehicle exhaust smell). Eventually I was able to move back into the parking area and needed to be towed. I have yet to have it evaluated by a dealership as they are closed today. Following multiple previous hybrid system recalls since purchasing the vehicle Oct 2022, I've experienced numerous malfunctions of the hybrid system (taking it to the dealership multiple times to be evaluated after the "wrench" service hybrid electric system warning showed) over the last 6 months. Each time I've been told a "software reset fixed it" by the dealership. …
