I am reporting repeated, sudden losses of motive power at highway speeds in my 2024 Jeep Grand Cherokee 4xe (PHEV). The vehicle's propulsion, electrical, and engine systems completely shut down without warning, causing the car to randomly stop while cruising at 60 mph on the highway, creating an immediate and severe crash risk. Despite the authorized dealership (David Auto of Glen Mills, PA) claiming that all outstanding safety recalls regarding drive power loss were resolved, the defect has actually worsened. This critical failure has occurred on at least three separate occasions recently: Late September 2026: Initial sudden power loss while cruising at 60 mph on the highway. [XXX]: Second instance of sudden power failure at 60 mph on the highway. [XXX]: Third instance of complete power loss at 60 mph on the highway. The vehicle was carrying four occupants at the time, significantly compounding the severe safety hazard. The manufacturer and authorized dealerships have failed to permanently rectify this dangerous defect, and the authorized recall remedies, stated complete, clearly have not or did not fulfill the obligations of safety and what was notified and communicated to me by Stelantis FCA (JEEP). As you may know, the ongoing, unresolved hazard is currently the subject of an active breach of warranty lawsuits and actively litigated. The vehicle is unsafe to operate on on highways due to these unpredictable hybrid powertrain shutdowns randomly at highway speeds, capping mph at 60 even if you are going 70+, and flooring the car in a passing lane or attempting to avoid other cars. It needs further investigation, and is a known issue apart of the hybrid systems failure and subsequent recalls yet no resolutions. ADDITIONALLY NO warning lights came on when this occurred. Video and 1st and 2nd person witnesses were taken as this is the 3rd time its occurred. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vehicle experienced a sudden loss of motive power at highway speeds without warning. The vehicle lost total propulsion at 60mph with zero dashboard error text or warning lights. Driver pressed fully on gas pedal to avoid activating the regenerative braking system. Driver pumped gas pedal but no response from vehicle. Vehicle began to lose speed while operating on an Interstate Freeway in the dark (between 6a - 7a). Driver began shifting into Neutral and back to Drive which only restored power for one second before cutting out again. There are no text errors or engine indicating warnings or alerts. Vehicle stalled and driver put on hazards and slowly made way to the shoulder and nearest exit ramp which was ~2 mile from event start to exit ramp. Event happened September 18, 2026. Another identical event on the same stretch of Interstate reoccurred on October 2, 2026 which prompted owner to take to the dealership for diagnostic. Jeep dealership was unable to diagnose or duplicate the issue.

While travelling on [XXX] in [XXX], and exiting on to I-80 [XXX] the vehicle failed to accelerate past 60mph almost causing a major accident during high traffic. The vehicle failed to respond above 60 in Hybrid and E-Save mode and I had to exit immediately. This incident is following 12 recalls with the vehicle (2024 Jeep GC Plug-in Hybrid 4xe). The vehicle is currently at Salt Lake Valley under major engine repair and a claim was submitted to Jeep Customer Care. No warning messages occurred at the time of the incident. I have not been told what actually happened or the reason for the failure from Salt Lake Valley Jeep. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

Continuously losing power while driving. It almost feels like a drop in power and a tug backwards. It’s not the same as regenerative breaking as I am familiar with that concept. Yesterday it responded differently. Instead of losing power there was a burst of power which almost caused me to crash into the vehicle in front of me. Lastly for the last 6 months my car fuel gauge doesn’t work correctly. It gets stuck at half and doesn’t register the gasoline put in til miles later. This has caused me to run out or gas 3 times, something that never happened in my other vehicles.

This vehicle has experienced repeated mechanical and electronic failures since delivery, including hybrid drivetrain faults, heating system malfunctions, and multiple diagnostic repair attempts. The vehicle is also subject to active Safety Recall 78C, which identifies a manufacturing defect that may cause catastrophic engine failure and vehicle fire risk. The manufacturer has acknowledged that a repair remedy is currently unavailable. The dealership that sold and serviced the vehicle has also recently ceased operations following acquisition by Carvana. These conditions materially impair the vehicle’s safety, reliability, and usability.

Hello, I am reaching out regarding a serious safety issue involving my 2024 Jeep Grand Cherokee 4xe under an active recall (78C), which Stellantis has acknowledged can cause an engine fire or sudden loss of vehicle function. Despite the severity of this recall, there is currently no remedy available. I have contacted Stellantis corporate multiple times and have been met with consistently poor customer service, including being told I am not allowed to open another case because my issue is “irrelevant” due to it involving a recall. I am leasing a vehicle that is not safe to drive, with a known fire risk and no repair solution. I have formally requested that Stellantis buy back the vehicle without penalty given the safety risk and inability to use the vehicle as intended. They have refused to accept the vehicle back or offer any meaningful resolution. This raises serious concerns about consumer safety and corporate accountability—particularly when a manufacturer acknowledges a defect but refuses to take responsibility for removing unsafe vehicles from the road.

Vehicle is a 2024 Jeep Grand Cherokee 4xe (PHEV) subject to Safety Recall 78C (25V‑766), issued November 2025. The recall states the engine may be contaminated with sand from the casting process, which can cause catastrophic engine failure, vehicle fire, and unexpected unrecoverable loss of propulsion. No remedy has been developed or made available by the manufacturer as of April 2026 — more than five months after the recall was issued. The manufacturer has confirmed in writing that an active stop-sale and stop-production order is in effect on all affected 4xe models due to this unresolved defect. Despite this, the manufacturer has simultaneously deemed the vehicle "operable" and denied a buyback request, requiring the consumer to remain in possession of a vehicle that cannot legally be sold due to its unresolved safety status. The manufacturer's written target window for the remedy was February–March 2026. That window has passed with no repair available and no updated timeline provided. The consumer has been without full use of the vehicle since January 2026 and has been paying out of pocket for rental transportation. The defect has not been confirmed by a dealer because no remedy exists for dealers to perform. No crash, fire, or injury has occurred, but the consumer has chosen not to operate the vehicle due to the known fire and catastrophic failure risk documented in the recall notice itself.
