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 & Out-of-Service Timeline: The vehicle was surrendered to an authorized dealership (Classic Chevrolet, Grapevine, TX) following the crash and has remained continuously out of service in dealer custody since June 14, 2026. General Motors Product Assistance Claims (PAC Case #102143673) closed their investigation on September 2, 2026, performing $0.00 in repairs and issuing a complete denial of assistance. The vehicle remains completely unrepaired, unsafe to drive, held in dealer custody, and subject to an active Texas DMV Lemon Law filing.

Was driving on highway and parking break light flashed on - break was not on. Tried to turn off and couldn't - car still driving. Then all these alerts started coming up "break failure", "no AWD" "Break failure cannot accelerate past certain speed". I tried to pull over the stop the car and no breaks would work including parking break. Eventually rolled to a stop without hitting anything. Car under warranty with 11,000 miles, called dealership who had lack of concern for urgency of the issue. This put not only myself and child but also many other drivers on the highway during rush hour. Very concerning and lack of response from dealership even more concerning.

What component or system failed or malfunctioned, and is it available for inspection upon request?

The vehicle subsequently struck a concrete wall. The vehicle is available for inspection upon request. How was your safety or the safety of others put at risk? On September 12, 2026, my son parked the vehicle on the top level of a parking garage. He exited the vehicle while I remained seated in the rear seat and his girlfriend remained in the front passenger seat. I later moved to the driver's seat to speak with her. As I exited the vehicle to meet my son, the vehicle unexpectedly started rolling forward on its own. Nothing was touched or intentionally activated prior to the vehicle moving. Because the vehicle began moving while I was exiting, I fell and suffered injuries including a scraped knee, swelling and injury to my foot, pain in my hands, and abrasions on my arm. The vehicle continued rolling and struck a concrete wall, causing damage to the front of the vehicle. The unexpected vehicle movement placed me, the passenger, and other nearby individuals at risk of serious injury. Has the problem been reproduced or confirmed by a dealer or independent service center? I am reporting these incidents for investigation. The vehicle is available for inspection by Chevrolet, the dealer, the federal safety agency investigators, insurance representatives, or other authorized parties. No warning lamps, messages, or other alerts were observed prior to the Rear Automatic Braking events or the vehicle roll-away incident. The braking events and vehicle movement occurred unexpectedly and without warning. I no longer feel safe operating this vehicle.
