2023 JEEP GRAND CHEROKEE Complaints

Was driving in a neighborhood and slowly turning at a 4 way stop, parking brake self engaged causing the car to slam to a stop and was unable to press gas. Had to put the car in park and restart (with shutoff for 30 seconds) before I could move and was stuck sitting in the middle of an intersection.

Driving in [XXX] in the HOV lanes on the evening of 22 June, the car traveled over an uneven section of the road. Heard a noise and felt the car go over a small bump. Car ride felt slightly different and continued on to home. Next day, looked at cat and the rear end was sitting uneven. Right rear lower than left rear. Looked under the rear of the car and saw the right rear coil spring was not there. The left rear spring is still in place. Prior to this, there was no problem with the ride or suspension of the car. There are no warning lights on the dash currently or prior to the spring falling off the car. I am not driving the car to to what I consider an unsafe condition. I am making an appointment at the dealer to get the problem resolved. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vehicle: 2023 Jeep Grand Cherokee Trailhawk 4xe Problem Description: While driving at highway speeds, the vehicle suddenly loses all propulsion and displays a message stating: “Put in Park Before Restarting.” This happens without warning, creating an immediate safety risk in traffic. The engine shuts down, and I am forced to stop in the middle of the road, shift to park, and manually restart the vehicle. This has occurred multiple times. The dealership and Jeep customer service acknowledges the issue but says no repair is available and has not resolved it. I’ve also been without a reliable vehicle since February 2025. I am aware of NHTSA complaints #11579877 and #11576290 describing identical problems in the same make/model/year. I believe this defect is related to the battery or hybrid powertrain system and poses a serious safety hazard to myself and others. I am also aware of NHTSA Recall 24V720000 related to battery issues, which may be linked to this sudden power loss. Symptoms: •Sudden loss of drive power •“Put in Park to Restart” message •Dash warnings (wrench/lightning bolt/hybrid system fault) •Must restart car to regain function Date problem began: [Feb 2025] Mileage: [17000] Vehicle still unrepaired and unsafe to drive.

We were driving our 2023 Jeep Grand Cherokee 4xe and pulled into a parking lot and put the vehicle in Park. At this point the vehicle started flashing the battery light and would not turn off nor were we able to put the vehicle in drive. Essentially the entire vehicle was just sitting and running, but was inoperable and we were unable to shut the vehicle off. We left the vehicle running and walked away with our key fobs, but the vehicle would still not shut off. It's a safety issue to have a vehicle running and not be able to put it inn drive or turn it off. We had to call a flat bed tow truck. The vehicle is currently at the dealer and they are not sure what is wrong with it. The warning lamp that came on was the red battery light and Auto Emergency Braking - Active Braking On was flashing across the screen, but the vehicle wasn't engaged in driving. We have the fob information from when we dropped the vehicle off, but nothing has been confirmed.

I was traveling on the highway at highway speed during peak commuting times when a notice to service hybrid system was displayed on the gauge cluster. The vehicle then lost all acceleration and shut down. I had to safely navigate to the side of the road with zero ability to accelerate or brake in fear of not being able to get off the roadway safely. I was automatically shifted into park once I reached a speed of around 5 mph.

There was a recall for my cars, hybrid electrical system. We were told not to park it in the garage, not to plug it in, etc., for months. That was in the fall of 2024. In December, I had to have my car towed to the dealershipto have regular battery replaced under warranty, and while it was there, Jake Sweeney Jeep, in Cincinnati, allegedly did the recall service. Immediately thereafter, my car started losing power while I was driving, with a message reading, Service hybrid electrical system.“ My car has been back to the dealership four times, I had a Starr case opened with Jeep, and was told that they are aware of the problem, don’t know when it will be fixed, and that I should take the car back home. It has happened when I was driving 65 mph on a highway, complete loss of power, I had to limp over to the shoulder, then back to the dealership. The codes were red, and the technicians said they were aware of it, but had no fix for it. They said they even had some units for sale on their lot with the exact same problem. At this time, Jeep is saying they do not know when They will have a fix for this on the hybrid vehicles. This seems very unsafe to me, because it happens, intermittently, at all different speeds.

Multiple incidents of the vehicle displaying a Service Hybrid System that appears for several seconds and then disappears. Today this occured, the engine abruptly switched to gas mode from hybrid with a sudden lurch, then returned to hybrid mode and the light disappeared . Vehicle has been to dealership twice for the service hybrid System light and no code is stored and they could not diagnose any further.

My windshield has small bubbles in the laminate layer between the glass. It is only noticeable in the early morning and sunset when the sun shines directly through the glass windshield. The safety concern is at night when it is raining. When an oncoming car headlights come through the glass it is impossible to see the road. I have to slow down considerably. Hopefully the road is straight at this point because I cannot see the road. At first I thought my windshield was just dirty. After cleaning the windshield many times the issue did not go away.

3 instances of complete loss of power, 1 while driving. Vehicle came to a hard stop as though I had slammed on the brakes. Dealer and Jeep have acknowledged the problem as a known issue. Jeep is saying it's safe to drive, but dealer agrees it is not and is not returning the vehicle to me. All dash lights came in during each instance and gave the error message "Service Now, Hybrid System Failure." Summary of the 3 instances below. It has been at the dealer since 5/8/2025. 3/29/25 approx 6pm I was stopped, and the error message came on and vehicle shut off. Attempted to restart approximately five times. Let’s sit for a few minutes, vehicle restarted and all error messages went away. 4/23/25 6:30pm Driving at low speed, air Messages came on vehicle abruptly stopped, narrowly avoided, getting rear ended, passengers complaint of neck pain. Engine turned on, all error messages immediately went away. 5/6/25 5:35pm Error messages came on while driving, engine started, no impact to driving. Error messages went away almost immediately. Jeep S.T.A.R. case was created

The vehicle has been regularly throwing an error saying Service Hybrid System and having a massive stutter in power while the hybrid motor shuts off and the engine is started to try and take over immediately. The vehicle has been in the shop for this previously, only to be returned to me saying they don’t have a fix for the problem and to continue to drive it. This happened again at highway speed and caused a near immediate loss of 10-15 miles per hour and were it not for evasive driving on my part and the other car, would have caused an accident. This powertrain has major issues that continue to happen.
