2022 Jeep Grand Cherokee Transmission Problems

Mileage when the problem started

Owner reports

Selected complaints filed with NHTSA by 2022 Jeep Grand Cherokee owners, lightly cleaned up (personal details are redacted by NHTSA).

I am a victim of SUA (sudden unintended acceleration. I entered my driveway and had my foot on the brake petal. Before I could shift into Park, the vehicle revved to a high RPM and then took off like a rocket. Brakes were initially hard to press and then the petal went to the floor, and I lost the brakes. This all happened very quickly and took me by surprise. I crashed through a double cyclone gate, closed garage door, back of the garage, double fence in back of garage, neighbors jacuzie and shed, hit the side of another neighbor's house and AC unit. It seemed that the power train electronics malfunctioned and caused all of this. Progressive insurance took procession of the vehicle and declared it a total loss.

The contact owns a 2022 Jeep Grand Cherokee. The contact stated while driving at an undisclosed speed, several unknown warning lights illuminated. The contact stated that the unknown warning lights indicated powertrain failure. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact stated that the vehicle had been scheduled for an upcoming diagnostic test. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 50,089.

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. …

Within days after completing the 95b recall (24v-720) on my Grand Cherokee 4xe PHEV , the vehicle would periodically flash an error message saying "service hybrid system" or something to that effect. It would illuminate for just a few seconds. On May 21, I took the vehicle back to the dealership (Brigham-Gill, Natick, MA). They read several codes and after conferring with Jeep, said the vehicle is unsafe to drive. It has remained there parked in their backlot as of July 15. The dealership is awaiting guidance from Jeep and informed me they have several others in the same situation. So there were few issues here 1) if I hadn't returned to the dealership to ask about these brief flashing messages, I would not have known that the vehicle was unsafe to drive. These messages never stayed illuminated for more than a few seconds, and there is no residual "check engine" light. …

After dealer installed recall 24V-720 on 1/15/2025, I started seeing Red Wrench light and warning to Service Hybrid System a few times each month. The warnings only flashed for a few seconds and disappeared - no service engine light. Also, the vehicle failed to charge about half the time. In early May, I was driving (in hybrid mode) about 45 miles per hour, and the Red Wrench light and warning to Service Hybrid System flashed and disappeared. The car would NOT accelerate! I DRIFTED to a safe spot, turned off the car, and restarted and now could accelerate. I was lucky! I brought the vehicle to Jeep on May 19, 2025. It was there for about 10 days and they found nothing - not able to reproduce and no errors logged, etc.They created a STAR Case (#1020705742) and still no solution. This is exactly recall 25V-576. …

The vehicle has experienced recurring safety-related issues associated with the hybrid electrical and propulsion systems. During normal operation, warning messages related to the hybrid system appeared, and the vehicle entered reduced functionality or became unreliable to operate. These conditions created concern about potential loss of propulsion while driving. In addition to propulsion concerns, the vehicle was subject to manufacturer recalls related to the high-voltage battery system, including warnings regarding battery overheating and potential fire risk. Recall-related service was performed by an authorized dealer; however, safety concerns persisted after service was completed, and confidence in the safe operation of the vehicle was not restored. …

My car was showing a "service hybrid system" warning light in the months of April and May 2025 intermittantly along with a slight loss of power. I took it to the dealership and was told its a software issue but it's fine. Stellantis is aware of this issue but there is no fix. I brought it back a week later with the same concerns and reading the document the dealership gave me - the 95B recall fix apparently crashed communication modules with my ORC. I expressed safety concerns. The dealership once again cleared codes and told me it was safe to drive. One week later on May 8, 2025, I was driving home from work. Without warning, the car locked up and went limp in the middle of the road. I went from 35mph to 0mph without seconds. I luckily was not rear ended. The dealership opened up another case with STAR. I have since gotten rid of the car due to continuous recalls and issues. …

The red wrench light keeps coming on, Hybrid system needs repair. It looses power for a short period of time, every time has been on the freeway. It makes a hugh crunch noise(transmission) and slams into gear. It is available for inspection, currently at dealership, it has been there for last week. This problem has been persistent, its been in many times for this issue. Chrysler told me they do not have a fix. It is all over the chat forums. We do not feel safe driving this car because it looses power temporarily and on the freeway. Many others are having problems with it stopping from a loss of power. It has been inspected by the dealership and in for repairs many times. This vehicle has been in the dealership on a regular basis since it was new. It has always had a power train issue, clunky and loss of power. Now it is worse and they don't have a repair. …

Timing cover leak, replaced by dealer once covered under warranty. Few months later same leak occurred in the same park after dealer replacement. Back to the dealer to have checked, dealer found that the head gasket during manufacture/casting has defect causing the head gasket to protrude into the mounting surface for the timing cover gasket/seal causing improper seal and securement. Dealer got Jeep engineers involved and found it was during manufacture and assembly/casting process. New head gasket being replaced and installed inspection of all mounting surfaces on cylinders valves and pistons for additional damage, and replacing timing cover gasket again. …

Driving home and car had a sudden loss of power randomly while driving. It would not restart until 5-10 minutes later despite multiple start/stop attempts. On the screen it stated to "plug in to condition battery." We were in the left lane on a busy road with construction and were almost rear ended multiple times while car was not functional. Have had multiple issues with battery on this 4xe - did recent software update at dealer. I have taken it to dealer previously for battery code (service battery) and they stated they can see code, but unsure of what problem is. No warning lights prior to incident. It sounds like through reviewing on internet this is a common problem with 4xe vehicles and if it hasn't killed someone yet, it certainly will. We did call 911 for assistance due to the vehicle being disabled in middle of highway, but no official report was made.
