    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

    The contact owns a 2023 Jeep Grand Wagoneer. The contact stated that while his wife was driving approximately 65 MPH on the highway, the vehicle lost motive power and shut off. The vehicle was later towed to the local dealer, who diagnosed that the thermostat had failed, causing the engine to overheat. The contact was informed that the valve inside the thermostat had bound, causing improper internal operation of the thermostat. The thermostat was replaced, and the vehicle was repaired. The contact was informed that per TSB: 09-006-25, the same style thermostat was installed to repair the vehicle. The manufacturer was notified of the failure. The failure mileage was 17,500.

  • Visibility/wiper 07/27/2025

    The driver side sunvisor comes loose and dangles causing an unsafe driving condition. Dealership has repaired multiple times but it continues to happen. It is an inherent design flaw that is going to cause accidents and ultimately loss of life.

  • Electrical System, engine, forward Collision Avoidance 07/12/2025

    While driving my 2023 Grand Wagoneer the Serv 4WD light and dash spelled out Service four wheel drive, it lit up the anti collision light, ECS, TCS, and HOLD!. The parking brake also engaged automatically while driving at least 4 times. This is a serious safety concern to allow a vehicle to continue driving with the ability to automatically engage the parking brake while driving. The safety of my entire family was put at risk. I currently have the vehicle sitting at the dealership to be diagnosed and reproduced as the vehicle lost all power after this incident. Another serious safety concern is the total loss of power with no notice. This could easily have been while I was driving and caused a serious accident and possible fatalities.
