2024 Jeep Grand Cherokee

I am submitting this complaint regarding Recall 78C (NHTSA Recall 25V-766) affecting my 2024 Jeep Grand Cherokee 4xe. The recall states that engine block casting contamination may result in catastrophic engine failure, loss of propulsion, and possible engine fire. This recall has now been open for approximately 120 days without a remedy available. Stellantis has confirmed that engineers are still working to develop a repair and that customers will be notified when a remedy becomes available. Since purchasing this vehicle in May 2024, it has been subject to five recalls within approximately 18 months of ownership: Recall 78C – NHTSA Recall 25V-766 Recall 68C – NHTSA Recall 25V-741 Recall 73C – NHTSA Recall 25V-576 Recall 28C – NHTSA Recall 25V-472 Recall D5B – NHTSA Recall 24V-944 Due to the severity of the defect described in Recall 78C and the number of recalls affecting this vehicle, my family has lost confidence in the safety and reliability of the vehicle. My wife is currently unwilling to ride in the vehicle because of the risk described in the recall. With a newborn child arriving next week, this situation has placed significant strain on our household because we are effectively operating with only one vehicle. I am submitting this complaint to document the ongoing safety concern and the extended delay in providing a remedy for this recall.

The vehicle has now experienced two complete electronic system failures while driving at approximately 45 miles per hour. During both events, all dashboard warning lights illuminated, and I lost power steering and brake assist. The engine remained running during the failure, but vehicle control systems were disabled. The first repair was documented as a disconnected electrical component, but the same full failure has occurred again. I consider this a serious safety defect, and I do not feel safe operating the vehicle

CRITICAL RECALL: NHTSA 25V-766 / FCA 78C (NO REMEDY AVAILABLE SINCE NOVEMBER 6, 2025) Status: INCOMPLETE - REMEDY UNDER DEVELOPMENT Risk Level: CATASTROPHIC Safety Risks: • Sand contamination in the engine from a manufacturing defect • Catastrophic engine failure • Vehicle fire • Unexpected and unrecoverable loss of propulsion while driving • Vehicle crash without prior warning • Risk of occupant injury or death • Risk of injury to persons outside the vehicle • Property damage Current Status: 'Remedy is under development' - NO FIX EXISTS. This recall has been open for 82 DAYS (since November 6, 2025) with no estimated timeline for repair parts availability. For nearly three months, FCA US has acknowledged that this catastrophic defect exists but has failed to develop or provide any remedy. Recall 78C: "The 2.0L engine in your vehicle may be contaminated with sand from the casting process. Sand from the casting process can contaminate internal engine components, leading to a catastrophic engine failure, which can result in a vehicle fire or an unexpected and unrecoverable loss of drive power. A vehicle fire can result in increased risk of occupant injury and/or injury to persons outside the vehicle, as well as property damage. A loss of drive power may result in a vehicle crash without prior warning"

My vehicle is subject to FCA Recall #78C / NHTSA Recall #25V-766, which identifies engine contamination that may lead to catastrophic engine failure, vehicle fire, or unexpected and unrecoverable loss of propulsion, potentially resulting in a crash without prior warning. The recall is currently listed as incomplete, with the remedy under development and no repair parts available. I contacted Stellantis Client Services to request guidance regarding safe operation of the vehicle while this recall remains unresolved and to inquire about any interim accommodations or support. Stellantis has advised me in writing that no assistance, accommodations, or compensation are available at this time and that I should wait until a remedy becomes available. Given the severity of the risks acknowledged in the recall and the absence of any interim safety guidance or mitigation measures, I am submitting this complaint to document the situation and request review.

The contact's mother owns a 2024 Jeep Grand Cherokee. The contact stated that the vehicle was difficult to start. Additionally, the transmission had failed to shift to drive, and the vehicle failed to turn off as needed. The vehicle was towed to the dealer, but the cause of the failure could not be determined. The contact was able to drive the vehicle to Lowe's and purchased and personally replaced the battery. The contact stated that the failure persisted, and the key fob was replaced. The contact stated that the vehicle lunged forward after shifting to drive(D). The vehicle also jerked while depressing the brake pedal as if the vehicle was attempting to accelerate. The check engine warning light was illuminated. The contact received notification of NHTSA Campaign Number: 25V766000 (Engine); however, the part to do the recall repair was not yet available. The dealer was contacted and advised the contact that the vehicle needed to be diagnosed; however, the contact related the failure to the recall. The vehicle was not diagnosed or repaired. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the failure. The failure mileage was approximately 10,782.

While driving in the Los Angelas area on March 24, 2025, on the 210 Freeway approaching the 605 Freeway the vehicle abruptly decelerated from 65mph to 45mph. A message appeared instructing "continue to your destination, do not turn off your engine, if you turn off your engine you may not be able to start it again." We contacted Jeep Connected who directed us to Cerritos CDJR. As we were heading south on the 605 Freeway the vehicle again abruptly decelerated to 28mph. This placed us in a dangerous safety situation as we were at the height of the afternoon traffic. The Service Advisor was able to determine that the Valve Body(VB) and Transmission Control Module(TCM) had failed. Also, both batteries were fully drained of their charge. The mileage was 4095. The comment was that the batteries contributed to the VB/TCM failure. We have continued to experience battery degradation with five (5) batteries having been replaced within the first year of ownership. We continue to identify battery degradation to the dealership but have received no correction to this defect. Over the past four (4) months we have documented "resting" battery voltage at a level where they are at or below 50% of their expected lifetime. While it is suggested that parasitic drain is the cause, we continually ensure that lights, radio, heating and air-conditioning and Jeep Connected are turned off when parked. I have documented to the Utah Division of Consumer Protection and NCDS these conditions. The ruling from NCDS is: DENIED. "I have reached this conclusion for the following reason: the customer did prove by shop work orders a Manufacturer defect does exist with the batteries discharging, which has affected the use and safety of the vehicle. However, there has only been three repair attempts with replacing batteries which is not considered unreasonable in my opinion." With the recognition by an Arbitrator that a manufacture defect exists which affects safety, it cannot be limited to my vehicle.

10/24 Loss of power while driving. Dash indicated vehicle was not on. Tried pushing the ignition button but received the message that vehicle could not start unless it was in park. Accessory power continued allowing me to pull to the side of the road. Fortunately I was not on the freeway but on a residential road. Was able to restart after putting the vehicle in park and drove the few blocks to home. Vehicle was operating in Hybrid mode and had 2% left on the battery so it had not switch to ICE mode at the time of the incident. Reported the issue to Jeep and they arranged towing to the dealership. Dealer reports no codes and cannot find an issue. Vehicle is still at the dealer as of 11/1. The September recall was done early in October and since then the hybrid warning light has not come on like it did before the software upgrade. Did not experience a loss of power before the recall software was installed.

On 10/19/2025, my 2024 Jeep Grand Cherokee 4xe experienced a serious electrical malfunction. When I attempted to start the vehicle, it became stuck in RUN mode and would not shift into Drive. The vehicle also would not shut off — even after pressing the start/stop button multiple times. The hybrid system remained active, and the dashboard stayed illuminated. The only way to power the vehicle down was to disconnect the 12-volt battery manually. This created a significant safety concern, as the vehicle could have remained running unattended or in an enclosed space. Afterward, the check engine light came on. The dealership later stated they “just reset the ECM,” but no explanation was provided for why the vehicle failed to shut off or shift out of Park. This incident indicates a possible defect in the electrical, powertrain, or propulsion control system. It poses a safety risk to occupants and anyone nearby if the issue reoccurs.
