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. Tea Chevrolet Customer Care INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION
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.
While my wife was pulling into park the car and pressing the brake, the car all of a sudden accelerated into the building. Pressing the brake failed to stop the car. No person was in the way of the car so no one other than my wife was at risk of injury. The problem has not been reproduced since the car was totaled. The car was inspected by the insurance for loss but that was it. Police and manufacturer have not inspected the car. No warnings were presented prior to the accident.
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.
Vehicle having multiple stalls with ABS light on while driving vehicle been at the dealership technician tried to repair it did not get fixed. Returned again stated that it was a wheel speed sensor. My vehicles been at the dealership for over two months now with no part ETA. Multiple instrument cluster lights and vehicle stalls while driving.
The contact owns a 2023 Chevrolet Blazer. The contact stated that while driving approximately 50 MPH, the vehicle experienced unintended acceleration and the speed increased to over 70 MPH. The contact indicated that while depressing the brake pedal the vehicle failed to slow as needed and the parking brake was activated to eventually stop the vehicle. The vehicle was later towed to the local dealer who was unable to determine or confirm the unintended acceleration failure. The contact was informed that the brake rotors and brake pads needed to be replaced due to excessive wear. The contact stated that during a previous unintended acceleration failure, the speed was reduced while depressing the brake pedal; however, the vehicle would accelerate when the brake pedal was released. The manufacturer was notified of the failure, but no assistance was offered. The approximate failure mileage was 9,000.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
