2024 Jeep Grand Cherokee Powertrain (other) Problems

My 2024 Jeep Grand Cherokee suffers from an intermittent but severe 2-to-3-second acceleration lag as well as lunging when attempting to accelerate. This occurs specifically during low-speed or rolling left-hand turns, or when accelerating from a complete stop to execute a left turn across traffic. When the accelerator pedal is depressed to clear the intersection, the engine and transmission momentarily fail to provide propulsion, leaving the vehicle stranded mid-intersection. This defect represents an immediate, severe collision hazard. Because the power cuts out while the steering wheel is turned, I have experienced multiple near-miss accidents where oncoming traffic had to slam on their brakes to avoid a broadside/T-bone collision. The dealer has not yet been able to permanently resolve this dangerous, unpredictable loss of driving power.

On August 8, 2026, at approximately 23,959 miles, my 2024 Jeep Grand Cherokee 4xe experienced a significant loss of propulsion while accelerating in Hybrid mode to merge onto a highway. During acceleration, the check engine light began flashing, then remained illuminated, and the vehicle displayed a “Service Hybrid System Required” warning. The vehicle then provided little to no effective motive power despite accelerator input, making it unsafe to continue the highway merge. I was forced to pull off the roadway and stop the vehicle. The vehicle could not be safely driven and required towing to a Jeep dealership. This vehicle has a prior history of hybrid-system-related repairs and recalls. Previous service included high-voltage battery recall work, control module programming, replacement of the electric coolant heater, and replacement of the auxiliary coolant pump and coolant temperature sensor after earlier check-engine-light, EV-mode, and Hybrid-mode drivability complaints. A prior repair order also documented jerking during deceleration and reacceleration while operating in Hybrid mode. The current dealer has been unable to reproduce the loss-of-propulsion event. During diagnosis, one or more vehicle control modules may have been reset or cleared, which may have removed stored diagnostic trouble codes or other event data associated with the failure. I am reporting this because the sudden loss of propulsion occurred during highway entry and created a serious safety concern.

Vehicle is an active fire hazard subject to the high-voltage battery recall (NHTSA 24V-718). The manufacturer's safety instructions require me to stop charging the vehicle and park it away from homes and structures. Because I am currently leasing this vehicle from Chrysler Capital and have no alternate transportation, I am forced to drive an active fire risk for daily transit. The local Jeep dealership has refused to provide a temporary loaner vehicle or rental accommodation while a final remedy is pending. The lack of a timely repair, combined with the refusal of the manufacturer to provide safe, alternative transit, forces me to operate a defective vehicle that poses an immediate safety risk to myself, my family, and the general public.

After recall 68c was completed the electric only power is way down. They did not fix the battery, they just reduced performance to try and minimize the risk and save them from replacing the defective part. This is not a fix but a fundamental change in the cars functionality as bought and is not acceptable.

I am submitting a complaint regarding NHTSA Recall 25V-766 affecting my Jeep 4xe vehicle. This recall states that engines may have been contaminated with sand during manufacturing, which can lead to catastrophic engine failure, sudden loss of propulsion, or vehicle fire. My vehicle currently shows the recall as open with the status “remedy not yet available / parts unavailable.” This means there is no repair available to address a known safety defect involving potential loss of propulsion and fire risk. I am concerned that sudden engine failure or loss of propulsion at highway speeds could create a significant crash risk for my vehicle, my passengers, and other motorists. Operating a vehicle with a known defect that could cause sudden engine failure while driving presents a potential crash hazard to occupants and other motorists. Owners are being asked to continue driving these vehicles despite the manufacturer acknowledging the defect and not yet providing a remedy. I respectfully request that NHTSA review the handling and timing of this recall to ensure a timely repair solution is provided to affected

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.

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.

While driving 70mph the vehicle had a sudden loss of power which required me to quickly navigate over two lanes of highway traffic to the right shoulder. I had no power or ability to accelerate. I was in hybrid mode with adaptive cruise control active. Upon safely making it to the shoulder of the road, I saw message on the dash saying something about electrical mode unavailable. I turned the vehicle off completely and back on again after waiting approximately 30 seconds. The error message cleared and the vehicle operated normally. This has not happened again after another 1,000 miles of driving, but it is currently being seen at the dealer for another issue with that will not allow electric mode operation, only combustion engine. We believe we may have a vehicle in the 1% outlined in NHTSA 25v-576 and are waiting a solution from the manufacturer.
