2023 Jeep Grand Cherokee power train problems

“On October 23, 2026, my 2023 Jeep Grand Cherokee 4xe unexpectedly lost propulsion. Before this incident, it intermittently shifted very harshly at 40–60 mph while I maintained steady accelerator pressure. That day, a “SERV 4WD” warning appeared and the vehicle tugged and jerked during turns. As I pulled into a parking space, it lost the ability to move. I turned it off. After waiting, I restarted it; there was a very loud thunk, and it suddenly lurched forward. The check-engine and brake warning lights illuminated, and it still would not move. When the tow truck driver restarted it, the loud thunk happened again. He was eventually able to reverse and move the Jeep a few feet onto the tow truck. He said it appeared to be staying in electric mode rather than transitioning to hybrid operation, although this was not a confirmed diagnosis. The Jeep was towed to an authorized dealership. The dealership says diagnostic scans pass and it cannot reproduce the failure. No cause or repair has been identified. My Jeep app shows safety recall 78C (NHTSA 25V-766), related to possible engine failure and loss of propulsion, with the status “Parts Unavailable.” The dealership…”

“I am writing to formally request a review of an unresolved safety recall on my 2023 Jeep Grand Cherokee. I recently received a notice regarding safety recall 89D/NHTSA 26V-562, which indicates a serious rear coil spring hazard. Currently, replacement parts are unavailable, still being developed and no remedy has been provided. Because this defect poses a severe safety concern, I cannot safely drive the vehicle. Being left without safe transportation-through no fault of my own-creates an extreme hardship. Under federal standards and manufacturer responsibility, owners should not be stranded or forced to drive unsafe vehicles waiting indefinitely for backordered parts that have been unsuccessfully developed two times already. I am requesting that Jeep corporate authorize a free loaner vehicle or full vehicle buy back at my local dealership; [XXX]. Please contact me promptly at [XXX] with a case reference number and details on how my alternate transportation will be covered.”

“The contact owns a 2023 Jeep Grand Cherokee. While the contact’s daughter was reversing the vehicle, the hybrid vehicle suddenly changed direction, and the vehicle drove forward approximately 3 feet and stalled. The vehicle was towed to the local dealer. The contact was informed that the part needed to repair the vehicle was on back order. No further information was available. The manufacturer was notified of the failure. The failure mileage was 64,000.”

“My wife was driving our jeep and it suddenly shifted into park while slamming the brakes on its own. She had to stay in the middle of the road shut it off & then start up and drive again but it keep happening the whole 20 mins stopping ride home.”
