New vehicle within 30 days of purchase date. Vehicle had just turned a corner and went a few more feet driving approximately 5 mph on a flat asphalt RD. The rear end suddenly shook violently, making loud clunking noises and shut off. Vehicle put itself into park. Tried to restart the car and it would only flash all the warning lights. Tow truck took it to Landmark Dodge Jeep in Independence, MO. The shop determined right rear rotor broke in half, and caliper broke off. The rotor breaking cracked inside of wheel. No damage to wheel well, fender, under carriage or body of auto in any way. Turned in the issue to Jeep as defective. They refused to fix it stating turn it into auto insurance. We refused to turn into insurance as it is defective parts. We asked Jeep for a black box report. Jeep refused to run it, so we hired a forensic company to take the black box reading which confirms no possible collision incident. Both black box report specialist and Landmark repair technicians note defective parts are a serious concern on this auto. This could be a larger issue for Jeep. If rotor had broken at a higher speed would have been very serious situation. We are concerned that other 2023 Jeep Grand Cherokee owners could be at risk. Jeep has still not responded to our escalation request. They keep advising someone will call us, but it has been over 45 days with no assistance from Jeep in any way. Car is still sitting unrepaired awaiting Jeep Wave escalation to contact us. We do not know if this situation is solely related to the rotor as it could be a larger issue with the vehicle traction control or drive line. We can provide the Semke Forensic Investigative Report findings done by a licensed Senior Mechanical Engineer with NHTSA but ask NHTSA to independently investigate. This is a serious safety concern. Jeep has completely failed to respond or protect us as customers.

My vehicle was stopped for several minutes on an upgrade, with stopped cars in front of me due to a traffic jam. I needed to keep pressure on the brake, lest my car roll backwards. After about three minutes, brake pedal lost pressure and my foot went to floor. The engine then went into gear and my car rammed car in front. Engine stalled on impact and was hard to restart. Vehicle currently at Jeep dealer awaiting inspection from Stellantis tech team. This situation reported to their customer care center. No warning lights appeared on dash prior to crash. Indeed, this could have been a more serious accident. I will never trust this vehicle again, and intend to take steps to exit my lease.

The vehicle while in cruise set at 70mph accelerated to nearly 90mph and would not disengage even when brake applied, had to turn vehicle off. It has done this twice almost causing an accident. Vehicle has also suddenly applied the brakes very hard while driving approx 55 mph, nothing in front of vehicle. Apparently vehicle was applying the brakes because when we reached home the brake rotors were glowing cherry red. Dealer has looked at it once and said in is probably our pedal getting stuck on the floor mats. I did not have foot on any pedal while in cruise. This last time no check engine light cam on.

I took delivery of the vehicle on February 15, 2023. On May 23, 2023 I was driving 35 MPH and without warning, I lost power steering and the brakes (felt like bricks when I tried to stop the vehicle). The vehicle never slowed and continued at 35 MPH. I had to swerve to not hit other vehicles as I was going through stop lights. I put the car in neutral and it slowed down and then put in park.after about 3-4 attempts of turning off/on, the steering started to work as did the brakes. I drove the.5 mi down the street with my hazard lights on back to my house. At that point the engine light remained on. The dashboard lit up with numerous alerts (I made sure to take pictures of everything). I called a tow truck and sent pictures to the dealership. They had the car for 2 days, called and said that they cannot duplicate the issue, despite receiving and reviewing the pictures I sent. They said no other option but to pick up the vehicle or let the service tech drive the vehicle overnight to see if the issue could be duplicated.

When slowing down at a stop sign, in snowy conditions, the vehicle went into brake assist and locked the brakes up. Causing the vehicle to slide at an interesting and collide with another car. I had complained several times to the dealer about the braking system being to sensitive and touchy before the accident. This was purchased new and the accident happened about 1800 miles on it. Also, the air bag did not deploy. I was told by the dealer, it was because the impact was not hard enough. But the alerts on my phone, said air bag failure Since the accident, I have had this jeep back to the dealer several times. I asked for a full brake inspection, because I have never driven a vehicle that 1- brakes for you for no reason, 2- extremely touchy. The dealer service dept admitted the brakes were touchy, and drove an identical model to compare, and concluded that it must be normal. Didnt actually inspect them. It is NOT normal, and I do not feel safe driving this vehicle in the winter. I have since turned off all brake assist options in the settings, but it is still auto braking. Today at about 3000 miles, when slowing down to make a turn, the emergency braking system started acting up with no one close to me. There is something very wrong with this system, and needs to be addressed before serious injuries happen.

On four separate incidences, the automatic emergency brake engaged while driving the vehicle at speeds in excess of 30 mph. There was no warning or reason for the emergency brake to engage. This resulted in the car needing to be towed to the dealer on two occasions as the vehicle froze and was not drivable. The dealer states they are unable to diagnose the problem or fix it as there are no codes that populate during the diagnostic session. This is an obvious safety hazard as this is a family vehicle with two small children in the rear seats.
