2024 Jeep Grand Cherokee L

While driving 45mph along a straight, open highway my vehicle suddenly shifted itself to park and stopped itself abruptly. I was then unable to shift the car out of park or move the brake or gas pedal or turn off the vehicle. This lasted for approximately 15 minutes and the car would not let me open the doors. All the dashboard lights were illuminated and my driver display screen stated if I took my foot off the brake the car would reverse. Eventually after 15 minutes of trying to shift and turn off the car it did shut off.

On XXX at approximately 630pm during rush-hour traffic crossing the XXX on [XXX], my 2024 Jeep Grand Cherokee Limited L (11,800 miles) the brake pedal went to the floor and the vehicle would not stop normally. The vehicle was towed to the dealer. This created a dangerous situation in heavy traffic with my child in the car and could have easily led to a collision. The vehicle was promptly taken to the closest authorized Jeep dealer. They diagnosed a Brake Vacuum Booster failure along with Diagnostic Trouble Code P057B-00 (Brake Pedal Position Sensor related). I have video footage of the symptom occurring and photos of the repair diagnosis. This is a new vehicle with very low mileage, and this unexpected failure raises serious safety concerns about potential defects in the brake system. I am requesting that NHTSA investigate this matter to determine if it affects other 2024 Jeep Grand Cherokees. Vehicle Information: • Make/Model/Year: Jeep Grand Cherokee 2024 • VIN: [XXX] • Mileage at time of failure: 11,800 miles • Date of purchase: 11/1/2024 No injuries or crash occurred, but the safety risk was SIGNIFICANT.

This car slams the breaks to a stop in the middle of an intersection while turning left with other cars across the intersection also turning left. It thinks we will hit but we are not going to. This has happened twice. Luckily, the driver behind us was paying attention both times and also slammed their brakes, avoiding a collision.

2024 Jeep Grand Cherokee L Summit Reserve was parked before a snow / ice storm and when we went to drive it 5 days later, after the storm, it would not move and made a loud explosion noise when I pressed the accelerator. I immediately turned the Jeep off and went to look underneath to see if I could see what happened. The rear brake pads and calipers were blown off, along with a bunch of broken parts and the air ride suspension was at its fully extended height. It's been to 2 Jeep dealers who can not explain what happened and Jeep says there is nothing they can do. We have only owned this Jeep, which was purchased new, for less then 20 months when this happened. If this had happened while driving, we could have had an accident and been severely injured. The Jeep is available at this time to be inspected. No lights were on prior to this happening.

I had my brakes flushed by my local dealer in June 2025 at about 31,000 miles for routine maintenance. I was traveling to York, Pa from Gravette, AR in September of 2025. All systems on my Cherokee had worked flawlessly on the trip, as they had since its purchase new in the Fall of 2023. On a very curvy, hilly road in the Cactocin mountain area, I was braking often. The ABS system warning light came on, as well as messages that the automatic collision control, lane departure control and adaptive cruise control were disabled. I noticed immediately that my brake pedal felt mushy and went nearly to the floor. Basically it felt like an old car with no power brakes. I proceeded to Gettysburg. When I restarted the car the error messages had cleared. I continued but after a few stops all of the error messages returned. When I got to York, still Thursday, I went to Stetler Jeep dealership and asked to have my Jeep looked at. The service clerk said no because I had no appointment. I asked to at least do an Obd2 scan so I know what the problem is. He said no, it can’t be done without an appointment. was told not until next Wednesday. I only planned to be in York until that Sunday. Between York and Decatur, IN on way home to Arkansas the warnings reoccured 3 more times, a total of 5. When stopped with my foot on the brake, when no errors showing, I would sometimes hear a clicking noise behind the steering wheel and feel it on my foot. A dealer in Indiana and my local dealer in Fayetteville, Arkansas could not find anything wrong. Those error messages have not appeared again without any repair. In December, my brakes were dragging and the brake waning light came on several times, then remained on. I could release the brakes by pumping them. My local dealer flushed brake system as the repair and warning light was gone. Two days later, brake system warning light is on again. I am taking it back to the dealer again even though brakes seem to be working fine.

My car shutdown from automatic braking and would not move, crank or engage into neutral. I was driving, turning at an intersection with the flow of traffic. Cars on both sides of me and behind me. It shut down as we were driving with no warning and would not start or move. My steering wheel locked. I had my childr j in the car and we were stranded in the middle of a crowded highly trafficked road and its nowhere to go and no way of moving out of the way.
