2024 Jeep Grand Cherokee fuel/propulsion system problems

“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…”

“While driving on the freeway - the cars hybrid system shut off altogether and wouldn’t go above 60mph. This was during maneuvers in traffic that cause severe concern for passengers in the car including my [XXX] daughter and wife, along with other nearby drivers.”

“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.”

“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…”

“Electrical system (Hy-bird System). Yes it's available for inspection. Yes my safety was at risk. Yes Yes No warning lamps, messages or other symptoms of the problem prior to the failure. After the first recall was completed.”
