Open the full vehicle complaint log (all categories)My brakes stoped working yesterday. The petal went to the floor and there were NO brakes. I was able to put the car in park and stop its movement. The vehicle is at the dealership. This is what they told me- BCSM AND ELECTRONIC BRAKE BOOSTER FAILURE. C0021
I have a 2024 jeep grand wagoneer. It has been activating it's emergency braking system randomly while driving. One time it was on a road with a 55mph speed limit the car beeped and slammed on the brakes. Morning sunny no traffic car was clean and free of dirt. Second time was on a 2 lane road speed limit 35 day light car beeped and slamed on the brakes the behind me had to go into oncoming lane to avoid hitting me. The 3rd time was after leaving the dealership after the 4th time in for service for them trying to figure out why the truck is doing this. Was on the cross street from the 2nd time. This time it high lighted a mail box in the night-vision mode and slammed on the brakes again day light no traffic car was clean. Mail box wasn't hanging in the road. We opened a case with FCA for a buy back they denied it. FCA also has not issued a stop drive order. We are currently using my wife's car to transport the kids as we do not feel comfortable with the issue not being resolved with FCA. My wife has the same truck hers is having the same issue but not slamming on the brakes hers is in currently with jeep engineering and they want us to record the car when it actives the system with our phones while driving. We feel very unsafe driving the cars and is hoping NHTSA can step in with some help. At the end of the day we are both trading our less than 1 yr old trucks in for another brand and is losing around 30,000 between the 2 vehicles.
