2023 Jeep Grand Cherokee 4XE

I was on my driveway getting ready to park and the parking brake engaged by itself. I came out of the car because I thought I had a flat but once I got back in the car, I saw the brake line was on. I called a friend with the same car and told him what happened. He told me to step on the brake and release the parking brake. I asked him where it was because I've never used it before. I did as he says and released the parking brake. This could have been catastrophic if I was on the freeway or driving on surface streets. I do not feel safe driving this vehicle anymore.

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.
