2025 Chevrolet Blazer problems

“Driving this vehicle in cruise control at around 70-80 mph, on an empty freeway early in the morning. No traffic but suddenly and for no reason the collision prevention system activated causing the steering wheel to turn all the way to the right and locking in place, the brakes activating, and leaving me no control sending me and two passengers in an embankment and the car on its passenger side.”

“The contact leased a 2025 Chevrolet Blazer. The contact stated that while in drive(D) or reverse(R), the parking brake independently engaged. An audible chime sounded, erroneously detecting nearby objects. The vehicle was taken to a local dealer. The manufacturer was made aware of the failure by telephone. The failure mileage was approximately 107,000.”

“Failed Component: Service Brakes, Hydraulic / Electronic Brake Control Module (EBCM) / Automatic Emergency Braking (AEB) Description of Incident & Safety Defect: On June 11, 2026, while operating the vehicle, the primary braking system suffered a complete failure of electro-hydraulic power assist. When attempting to slow down, the electronic brake system failed to engage or command hydraulic assist. The brake pedal became extremely hard and stiff to press, rendering the hydraulic braking system completely ineffective. Simultaneously, the vehicle’s integrated Automatic Emergency Braking (AEB) system failed to activate or provide secondary collision mitigation, resulting in a crash with the vehicle ahead. Technical & Telemetry Evidence: An official Bosch Crash Data Retrieval (CDR) report (dated July 29, 2026) confirmed that during the incident, the brake pedal was physically depressed to 16% pedal travel/movement, yet the hydraulic line pressure registered at 0 kPa. This electronic telemetry proves that despite driver pedal application, the Electronic Brake Control Module (EBCM) never engaged hydraulic pressure or commanded stopping authority. Post-Incident &…”

“While backing into parking at a Humble Cow ice cream place. My 2025 Chevy Blazer EV AWD slammed to a stop. I was going 4 mph my spouses head hit the head rest and caused severe pain and stress. We had to go to the emergency room for treatment. This has happened 6 other times 3 since having the required updates and replacement of modules that took several months to complete. She was given medication and lytocain patches for the trauma of her neck and head. She is now afraid to drive in my vehicle. I looked up the situation and found on Reddit and the internet that this is a known issue with Chevy and several other vehicles relating to their braking and eboost system. One work around is to turn off all of the sensors from the settings menu to include parking. It also said to not use the one pedal driving. This is unattainable for a brand new car that I paid Cash 45-50,000 for and not to be able to use it as intended. Please look into this. I will be filing another complaint with the dealership on 14 September 2026. Something must be done.”
