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.

During a standard service, the servicing dealership (Lester Glenn Jeep, Tom’s River,NJ) failed to perform the mandatory factory electronic scan bleed required for the Electronic Brake Booster (EBB) and ABS/ESC modules. This critical omission left unpurged fluid and internal system aeration trapped deep inside the electronic braking components, severely compromising the vehicle's stopping integrity and creating an immediate safety hazard. The safety omission was caught and documented via a secondary diagnostic scan by another authorized Jeep servicing facility (Pine Belt Jeep, Lakewood,NJ ), which had to perform the corrective electronic scan bleed to restore proper braking functionality and make the vehicle safe for public roads.

The contact owns a 2024 Jeep Grand Cherokee. The contact stated that while test driving at an undisclosed speed, an unknown warning light flashed on the instrument panel. The dealer informed the contact that the battery was low and that the light had been replaced, while also informing the contact that the vehicle had experienced difficulty starting prior to purchase. Days later, upon starting the vehicle, all warning lights illuminated and the vehicle stalled. The vehicle was towed to the dealer, but the dealer was unable to determine the cause of the failure, cleared the codes, and returned the vehicle; however, the failure recurred. While driving, the steering wheel became inoperable, causing the driver to lose steering control, and the vehicle crashed into a Ford Mustang. A red steering warning light illuminated. A police report was filed. There were no reported injuries, airbag deployment, or fire. The vehicle was returned to the dealer, where it was determined that the vehicle was undrivable, could not be inspected in the service bay, required an unknown replacement part, and that the steering wheel computer failed to communicate. The manufacturer was notified of the failure and advised the contact that the vehicle did not qualify under the lemon law, prompting the contact to report the issue to the Attorney General, who referred the contact to the NHTSA Hotline. The failure mileage was approximately 55,000.

As I was merging onto the highway my sunroof combusted without any impact that would cause it. Upon inspection there was no item that hit the glass, the glass shattered entirely across the entire pane and broke apart ( not just spiderwebbing, there was glass falling into the sun roof visor)
