2023 Jeep Grand Cherokee 4XE

My partner and I were driving from Oakland, CA to Petaluma, CA on [XXX], 2024. While driving approximately 75 mph the car shut down and i had to guide it to the side of the highway. It was frightening and we were almost was hit by passing traffic. The display screen and electrical system were going haywire - turtle sign to check engine to random messages stating the car was OK to start. After about 25 minutes, the car started on its own. At the time of the incident, there was just under a half tank of gas. In the weeks since, the car has randomly shutoff and turned itself back on. A nearby Jeep dealer in San Leandro, CA indicated he has heard of similar issue with other Jeep Grand Cherokees. Having read about this I do not trust Jeep as their response was "oh this happens with the 4xe." We purchased this vehicle in August of 2023 and have approximately 6400 miles on it. Fully maintained and no warning lights. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When crossing the border into Mexico the AEB module falsely reports it has malfunctioned due to "geo fence" limitations. At least that is the cause of the issue per the service department. This causes the AEB system to stay offline and inoperable which also affects the Lane Departure Warning System as well as prevents the use of Adaptive Cruise Control. Supposedly there will be a "Software Update" coming--it was supposed to happen in Q4 of 2023 and now they say Q1 2024 which has ended and no update. The safety of the vehicle is compromised as key safety features are offline.

Hybrid System, Air Suspension System, Engine, Power Train Car acceleration power cut out while driving 50 mph suddenly while driving down the road. Held up traffic when came to complete stop, vehicle would not restart immediately. Needed to restart vehicle multiple times before it started moving again. Problem has not been able to be reproduced by the dealer. They reset codes and took on a test drive and was not able to reproduce the issue. Vehicle has not been inspected by anyone other than the dealer. Currently Check Engine Light is on with Air Suspension Fault Light on as well. There was no warning to the vehicle losing power.

Driving Screen, Swaybar Disconnect systems, Airbags, TPMS, Driving controls such as blinkers, and emergency flashers. The car was functioning normally, with no anomalies or error messages, including through phone notifications. The battery charge was nearly complete. I engaged Electric-Drive mode and used regenerative braking to recharge the battery on my way to town. Approximately 30 minutes into the drive, and with the battery at 99% charge, I heard a loud pop. It sounded like it was coming from the right-side passenger control arm. Shortly after, my dashboard was illuminated with warning lights, including a check engine light and notifications about air suspension and sway bar disconnection, airbags, tpms sensors, and more. The car decelerated dramatically; The dashboard screen flickered on and off as if rebooting. I got the vehicle safely, but during that time, the car seemed to be in limp mode, unresponsive to acceleration, and stiffer than normal breaking. The steering was also affected. I realized that if I had been on the highway, this could have caused a severe accident. Screen, Powertrain, and drivetrain fail while traveling 45+ miles an hour. It is a small 2-way road in turn with mild car and foot traffic around. The dealer has confirmed the issue as an issue that has been present in past vehicles in this model category. The car had been in my possession for less than 24 hours/40 driven miles.

The contact owns a 2023 Jeep Grand Cherokee. The contact stated while driving 15 MPH, the “4-WD mode Disabled”, and that the Automatic Emergency Braking activated messages were displayed. The vehicle then independently turned off. The contact stated that there were no other vehicles in front of the vehicle at the time of the failure. The contact was able to veer to the side of the road. The contact stated that upon restarting the vehicle, the messages were no longer displayed. The contact continued driving; however, the vehicle failed to shift smoothly into the intended gear. The vehicle was taken to the dealer, where diagnostic codes related to the transmission valve body were retrieved. The vehicle was not repaired. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 1,100.

When ever I try to charge my Jeep grand Cherokee 4xe summit reserve it fails to charge on a level 1 or level 2 charger and then they check engine light comes on and a electrical burning smell from the hybrid battery and says service charging system. When ever you bring it to the dealer they just reset the code and says it works only for the problem to come back it also affects how the jeep drives when this happens the jeep doesn't want to accelerate properly and has other electric system issues like the wipers coming on randomly and the massage seats coming on randomly as well which can distract someone when they are not expecting that to happen the jeep doesn't want to drive. I brought it to the dealer 3 times now and all they keep doing is resetting the code and stating its fine only for it to come back and this is a major problem and needs to be fixed as this is going to cause a major accident or fire since it has to do with the hybrid battery system.

Accelerating onto hwy and vehicle jerks then flashes “service hybrid system” and “battery low” (as in the vehicle battery not electric mode charge. Pulled up to a stop light 2 min later and automatic breaking locks up and the vehicle completely locks and shuts down. Unable to reset/turn off/on or shift. Had to be towed to dealership.
