2023 Chevrolet Blazer Brakes Problems

Rear brake automatic parking brake motor locked rear wheels. Dealership diagnosed and repaired at my cost. Service parking brake light illuminated and rear brakes locked not allowing vehicle to be moved. After a few restarts brakes released.

The contact's father owns a 2013 Chevrolet Blazer. The contact stated that while his father was driving at approximately 40 MPH straight forward, the brake pedal was depressed, and it traveled to the floorboard. Then, the brake pedal was lifted, and the brake pedal traveled a second time to the floorboard. The vehicle did not slow down as intended, and the vehicle crashed into the rear of another vehicle. The air bag did not deploy, and no warning lights illuminated. The contact's father sustained a facial bruise. Medical attention was not needed. A police report was filed. The vehicle was towed to a lot where it was pending an inspection from the insurance company. The manufacturer was not notified of the failure. The failure mileage was 34,000.

Addition to Case #[XXX] Hi: Read the following response from Chevrolet Care at the end of this Email about my braking problem. Take Note That Chevrolet is Admitting that in a case like mine (wet, slippery snow conditions) I only have Basically Two Wheel Braking and those two wheels (tires) are sliding during the complete stop. This happens when driving in town (20 -25 mph) The rear wheels as Chevrolet says have a drag effect, (basically no braking) Chevrolet has created a crash Hazard with this over engineered braking system when used in wet slippery snow conditions. Thank You [XXX] See Enail from Chevrolet Cares Hello [XXX], Thank you for your patience and for providing this information. We received an update from your dealership, Bergstrom Chevrolet Of Manitowoc, who advised the following: The system is functioning as normal. Brake pad thickness was measured at 8mm on all 4 wheels. The ABS system doesn't activate on all 4 wheels unless there is a total loss of traction across all four wheels which would indicate a total loss of control. With two wheels activating and the rear wheels still spinning is allowing for the retention of control by allowing for braking to the rear wheels but at a lesser degree to create stability and drag (braking) to maintain control and steering capabilities during the loss of traction at the front end. The ABS system does allow for the adjustment of braking power to specific wheels in an effort to maintain proper traction and steering prior to the emergency systems engaging in the event of a slide. The dealership is our eyes and ears on the ground, and I will stand by their judgement. However, if you feel strongly against the dealership's judgement, it is to your discretion on what dealership you would like to work with. Please note, this does not guarantee a different resolution. Please let me know if you wish to visit another GM location for further assistance, we're here to help.

This problem is with a 2023 R/S/ AWD Blazer: When there is wet slippery snow, and I apply the brakes normally the system immediately goes to rapid clicking of the ABS system activated on the front brakes and I hear no clicks from the rear wheels. From the time of the ABS being activated the front wheels go into a slide and the rear wheels only roll along with no braking action as I have opened my driver's door and watched the driver's rear wheel while activating the brakes. I have been to the dealer two times, and they find nothing wrong. I found on the internet one other person complaining with the same issues as me on a 2021 R/S AWD blazer. When this happens, it is a accident waiting to happen situation.

The driver-side half-shaft disengaged from the transmission. This caused a roll away of the vehicle when it is thought to be securely in "park" gear cuasing a frontal colisión.
