2023 Jeep Grand Cherokee transmission problems

Filed Oct 27, 2026 · Electrical, Fuel system · CO

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 (the federal safety agency 25V‑766), related to possible engine failure and loss of propulsion, with the status “Parts Unavailable.” The dealership told me its scan indicates my vehicle does not need the recall, but has not clearly explained why. I do not know whether the recall caused this incident. I have opened a case with Jeep Corporate. I am concerned this unexplained loss of propulsion and sudden forward lurch could recur in traffic and cause a crash. I request that the federal safety agency document and review this potential safety defect.

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/the federal safety agency 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 high-voltage (HV) battery system and related hybrid control processor (HCP) software — repeatedly, across three separate incidents (Jan 2026 coolant heater/HCP fault, June 2026 front axle disconnect fault, Sept 2026 full HV battery replacement). Also affected: front axle disconnect actuator (drivetrain). Yes, available for inspection — vehicle is at Chrysler Dodge Jeep Ram of Clifton Park. - Recall 68C: HV battery fire risk (owners told not to charge, park away from structures). Recall 73C: possible loss of drive power while driving, increasing crash risk. Recall 20C: head restraints failing to lock, increasing injury risk in a crash. - Yes — confirmed and repair attempted by an authorized Stellantis dealer (Chrysler Dodge Jeep Ram of Clifton Park) on three separate repair orders (RO #106187, #109788, and the current September 2026 visit), with documented diagnostic trouble codes each time (P29BB, C1463, and the current critical HV battery code). - Inspected/repaired by the authorized dealer under manufacturer recall directives (FCA/Stellantis) each time. No police or insurance involvement, since no accident occurred. - Yes — Check Engine Light (Jan 2026, code P29BB), Service 4WD light (June 2026, code C1463), and Check Engine Light again (Sept 2026, current critical HV battery code). Recall notices (68C, 73C, 20C, etc.) were also received separately as advance manufacturer warnings before some of these symptoms appeared.

I am filing a formal safety complaint regarding my hybrid Jeep vehicle due to ongoing and unresolved safety issues that present a significant risk to myself and others. Since the beginning of ownership, I have experienced repeated and escalating problems with the vehicle, including: * Hybrid system malfunction warnings and persistent red wrench indicator * Aggressive and unsafe gear shifting while driving * Vehicle stalling unexpectedly * Vehicle intermittently failing to turn on or shut off properly In addition to these critical concerns, my vehicle has been under Recall 68C since October 2025. To date, there has been no available remedy provided. I have been explicitly instructed not to park the vehicle in a garage or near structures and to avoid charging the vehicle due to an increased risk of fire. This situation has created significant hardship and safety concerns. I am unable to safely use or store my vehicle as intended. I have also been informed that potential fire damage related to this issue may not be covered by homeowners insurance, further increasing the risk and liability I am being forced to assume. Despite repeated attempts to address these issues through proper channels, including dealership service visits and manufacturer communication, no resolution has been provided. This vehicle poses a clear safety hazard due to: * Risk of fire associated with the hybrid battery system * Unpredictable stalling and drivetrain behavior while in operation * Lack of manufacturer remedy for an active safety recall I am requesting immediate investigation, accountability, and corrective action to ensure the safety of consumers affected by this issue

The contact owns a 2023 Jeep Grand Cherokee. The contact stated that while driving approximately 40 MPH, the vehicle unexpectedly lowered and started pulling to the right. The vehicle was pulled over to the side of the road, and the contact exited to inspect the vehicle but found no failure. The vehicle was taken to the residence, and then to a dealer, where it was diagnosed and determined that the axle and passenger’s side rear tension link were bent and lodged into the knuckle, the passenger steering knuckle was fractured with a fractured bolt inside, and the passenger’s side rear tension link, CV axle, and steering knuckle needed to be replaced. The vehicle was repaired, but the failure reoccurred approximately 8 weeks later on the driver's side. The contact stated that while driving approximately 20 MPH, there was an abnormal sound coming from the rear passenger’s side of the vehicle, and the vehicle started pulling to the left. The vehicle was pulled over to the side of the road and inspected, but the contact found no visible failure. The vehicle was taken to the dealer, where it was determined that the driver's side rear axle and driver's side rear tension link were bent and had lodged into the knuckle, the driver's side steering knuckle was fractured with a fractured bolt inside, and the driver's side rear tension link, CV axle, and steering knuckle needed to be replaced.

The rear parking collision warning abruptly stopped working. The engine smells like it’s burning. The recall 68c has no remedy currently. My neighborhood is at risk due to this outstanding issue.

Powertrain/engine performance (acceleration control): vehicle struggles to accelerate when pressing the gas. Transmission / drivetrain (gear engagement / shift control): vehicle drops from Reverse into Neutral without driver input (unintended gear disengagement). Water intrusion: ongoing water intrusion, power tailgate was already replaced due to water erosion, when it rains or snows water gets into vehicle resulting in a musty/moldy smell and driver side mat soaking wet. Yes — the vehicle is available for inspection upon request. The loss of acceleration / hesitation / jolting creates a risk of being unable to merge, cross intersections, or accelerate in traffic when needed. The unintended shift from Reverse into Neutral can cause loss of intended vehicle control/movement while reversing (driveway/parking lot risk), increasing collision risk with nearby vehicles, pedestrians, or property. Reverse → Neutral: Reported to dealer multiple times; confirmation varies by visit (intermittent concern) Stellantis Customer Retention states they spoke with the service manager and confirmed the repair history and dealer visits, not necessarily a physical engineer inspection.
