“My 2017 Jeep Cherokee rolled away three times in one day while in Park with the Electric Parking Brake engaged. My driveway has no flat area and slopes toward a public road, creating a serious hazard for my family and traffic. The rollaways occurred suddenly with no warning lights. I had to park the Jeep sideways in a snowbank for two weeks to prevent further rollaways, creating added risks for my family in winter conditions. The vehicle remains at the dealership. During the first two days of the evaluation, the dealer confirmed brake shoe thickness (4mm), verified the EPB software was current, and found no diagnostic codes. They could not recreate the rollaway or identify a cause. No mechanical or electronic faults were found. FCA communication has been inconsistent. I experienced dropped calls, long holds, contradictory statements, and repeated refusals to provide written documentation of the inspection authorization. FCA said they could not escalate the safety case unless the vehicle was already at the dealership, yet still refused written confirmation of the purpose of the inspection, and I was not willing to bring the vehicle in without documentation.…”

“The contact owns a 2017 Jeep Grand Cherokee. The contact stated that while driving at 45 MPH, the vehicle went into LIMP mode and the vehicle stalled. The vehicle overheated due to the radiator not functioning properly. The check engine and brake warning lights illuminated. The vehicle was able to restart after numerous attempts. The vehicle was taken to an independent mechanic, where unknown parts needed to be replaced. The vehicle was repaired; however, the failure persisted. The vehicle was then taken to a dealer, where it was diagnosed that unknown parts needed to be replaced. There was a burning odor, which was later determined to be caused by mechanics leaving rags in the engine. The vehicle was repaired, but the failure persisted. The manufacturer was not notified of the failure. The failure mileage was approximately 100,000.”

“On [XXX], I was involved in an accident in Maryland while driving my 2017 Jeep Grand Cherokee. It was raining and despite attempting to slow down, brakes performed poorly, causing my car to skid and collide with the vehicle in front of me. Fortunately, no one else was injured, but I sustained a neck injury, and my car was ended up a total loss. During the accident, I noticed the ABS warning light had activated. This, combined with prior experiences of delayed brake response, raised concerns about the vehicle’s safety. Having derive. For over 15 years without incidents, this was my first major accident and I suspect it may be linked to a mechanical issue. After learning about recent calls related ABS/brake issues in Jeep vehicles, I felt it was important to report my experience. I urge you to re-evaluate the safety of the 2017 Jeep Grand Cherokee’s ABS and braking systems to prevent similar incidents in the future. Thanks”

“The contact owned a 2017 Jeep Grand Cherokee. The contact stated that the brake pedal was depressed while in the park position gear, the engine revved and the vehicle accelerated independently forward causing the contact to hit her head on the headrest. The contact confirmed by looking down if in fact her foot was on the brake pedal and it was during the incident. As a result, the contact crashed into the waiting room of a building. The contact remained depressing the brake pedal and shifted into reverse however her head hit the headrest again. The contact then attempted to shift into the park position but the vehicle continued to accelerate on its own and crashed into a parked Mercedes-Benz and then crashed into the rear door of a parked vehicle where the vehicle came to a stop. During the incident, the Anti-Braking System did not engage. The air bags did not deploy. The driver sustained a concussion and neck injury which later required medical treatment. The vehicle was destroyed and towed away. A police report was filed. The cause of the failure was not determined. The local dealer was notified of the crash but no assistance was offered. The manufacturer was…”

“The component is known to fail on jeep forums weather it fails completely or was not installed properly and may loose its functionality. The event is when towing a trailer and reversing the car will see the trailer as an obstruction and will engage the brakes. The car is alleged to have an automatic system that when towing is supposed to turn the parking assist sensors off to prevent the event occuring. If that system isn't present there is a button that should allow you to turn the parking system off which it does for about two seconds and start backing up the trailer, then it will automatically turn back on and see the trailer and lock the brakes up which is jarring and startling to say the least. I am fairly certain this could cause an accident if it hasn't already.”
