2024 Jeep Grand Cherokee: check engine light

Filed Aug 8, 2026 · Electrical, Fuel system · CO

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.

I am filing a safety complaint regarding serious and recurring issues with my 2024 Jeep Grand Cherokee that create unsafe driving conditions. Shortly after purchasing the vehicle, I began experiencing intermittent electrical malfunctions while driving. Without warning, multiple dashboard warning lights and signals activate simultaneously. During these events, I lose confidence in the vehicle’s reliability and safety, as it is unclear whether critical systems are affected. On at least one occasion, the issue forced me to pull over to the side of the road due to safety concerns. The vehicle would not return to normal operation immediately, and I had to repeatedly turn the vehicle off and on for approximately 20 minutes before it reset. In addition, the check engine light has been on for a significant portion of the time since I purchased the vehicle. I have taken the vehicle to the dealership multiple times, but the issue has not been permanently resolved. I am also concerned about multiple safety recalls affecting this vehicle. Some of these recalls currently have no available remedy, which increases the risk and leaves me driving a vehicle that may have known safety defects without a fix. These ongoing issues pose a serious safety risk to me and others on the road. I am requesting that this matter be investigated, and that appropriate action be taken to address these defects. Is it possible to switch to another safe Jeep model?

I am submitting this complaint because my vehicle’s driver seat has a dangerous and unpredictable defect that creates an immediate safety hazard. While the vehicle is in motion, the driver’s seat will suddenly and randomly move forward without warning, pushing the driver into the steering wheel and crushing the leg and footwell area. This is not a minor adjustment issue—it is a sudden mechanical movement that physically forces the driver into an unsafe position while actively operating the vehicle. This has occurred at highway speeds and in heavy traffic, which makes the situation extremely alarming. When the seat unexpectedly moves forward, the driver is forced closer to the steering wheel, restricting movement and making it difficult to properly steer, brake, or maintain control of the vehicle. In those moments, the driver’s ability to safely operate the vehicle is compromised. The only way we have been able to stop the seat from continuing to move forward is to perform an emergency maneuver, pull the vehicle over, completely shut the vehicle off, and restart it in order to reset the system. Until the vehicle is fully turned off and restarted, the seat will not return to its normal position. The vehicle has been taken to the dealership twice after the check engine light came on. Each time, we were told the light was being triggered by the “comfort seat module.” However, despite the system indicating an issue with the comfort seat module, the dealership stated they could not find any problems with the seat or the module itself. This situation is extremely frightening and dangerous. A driver being physically forced forward into the steering wheel while traveling at highway speeds creates a serious risk of losing control of the vehicle. This defect puts not only the occupants of the vehicle at risk, but also other motorists and pedestrians sharing the roadway. This issue needs to be investigated before someone is seriously injured or worse. No driver should have

Component Failure: This vehicle has suffered a recurring "Loss of Motive Power" (LMP) while in motion. On [XXX], for the third time, the internal combustion engine shut off completely while the vehicle was being driven in traffic. The vehicle is available for inspection upon request. Safety Risk: This incident occurred on a public road in New York during a severe winter storm with over a foot of snow on the ground. There were two children in the vehicle. The sudden loss of propulsion in heavy traffic and hazardous weather conditions created an immediate risk of a rear-end collision and left my family stranded without power or heat in freezing temperatures. Confirmation & Inspection: This is a documented, repeat failure. The manufacturer has confirmed the defect previously and even reimbursed me for a prior repair attempt. However, the issue remains unresolved. The vehicle was inspected by an authorized Jeep dealer during previous failures, but the "remedy" provided was ineffective. I am currently awaiting a new inspection for this third occurrence. Symptoms & Warnings: Prior to the total engine shutdown, the Malfunction Indicator Lamp (MIL) illuminated on the dashboard. In previous instances, the manufacturer cited software errors or internal contamination as the cause. I suspect this is related to existing the federal safety agency Recall 25V‑766 (Engine Sand Contamination) or Recall 25V‑710 (Hybrid Control Software Failure). Additional Context: Despite the life-threatening nature of this repeat defect, the local dealership refused to provide a loaner vehicle, and the manufacturer (Jeep Wave) is refusing to fully cover the cost of a rental vehicle. I am currently paying out-of-pocket interest on delayed reimbursements from the manufacturer. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2024 Jeep Grand Cherokee 4xe (VIN: [XXX] ) has experienced repeated safety-related failures. With only 3,169 miles, the vehicle became inoperable shortly after purchase and remained at a Florida dealership for 9 months waiting for parts. The hybrid battery and related components were replaced. After picking up the vehicle, while driving from Florida to North Carolina on [XXX], the Check Engine light came back on. A cooling system failure was diagnosed, which caused critical safety systems to stop functioning: the forward collision warning sensor, radar, and driver-assistance features all became disabled. A technician also discovered that a component requiring nine bolts was fastened with only two, indicating improper repair or assembly and creating a serious safety hazard. I brought the vehicle to AutoStar CDJR in Hendersonville, NC, where additional issues were documented: rattling/thumping noise under the vehicle at highway speeds, wind noise entering through the front windshield, and the Check Engine light still on. The advisor noted in writing that the vehicle had been in the Florida dealership for nine months and now shows new faults. As of December 7, 2025, the vehicle is again in the repair shop. I no longer feel safe driving it. The repeated failures of the hybrid/electrical system, cooling system, and critical safety sensors, along with evidence of improper assembly, represent a significant safety risk. I request that the federal safety agency investigate these defects, as they appear to indicate a broader safety issue with this model.

I purchased a used 2024 Jeep Grand Cherokee 4xe (approx. 64,000 miles) from EIDE Chrysler in Waite Park, MN on 9/30/2025. On the initial drive home, a “Service 4WD” warning appeared. Before I could return for the axle repair, a Check Engine Light for the hybrid system also appeared. After purchase, I also began experiencing exhaust fumes entering the cabin, which is a health and fire concern. At the time of sale, the dealership provided two contradictory recall printouts for the only recall they disclosed—one stated a remedy was available and one stated no remedy was available. I was verbally told the recall had been repaired. This was inaccurate. After the sale, I discovered that my vehicle now has two open the federal safety agency safety recalls, both with no available remedies: • 25V741 – High-voltage battery fire-risk recall (federal stop-sale order applies). • 25V766 – Engine contamination recall that may cause engine damage or failure. These recalls did not exist at the time of purchase, but the dealership never notified me when they were issued. Stellantis only notified me of one recall; I had to discover the second by checking my VIN on the federal safety agency’s site. The drivetrain warning, hybrid-system fault, and exhaust fumes occurred despite very low mileage after purchase. The vehicle currently has multiple unresolved safety defects, including fire risk and potential engine failure, and cannot be repaired due to lack of available remedies. I have opened a case with Jeep/Stellantis (Case #: 94881053). I am reporting these issues because the combination of drivetrain malfunction, hybrid-system warning, cabin exhaust fumes, and two unrepaired safety recalls poses a significant risk to occupants and other drivers.

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.
