| Service Brakes problems |
Vehicle is 2023 Chevrolet Corvette z06 with about 33000 miles. On xxxi was driving about 65 mph on [xxx] in the left lane with my wife as passenger. On a slight left curve the front brakes applied hard on their own without my input. The car slowed very rapidly. A semi truck in the right lane had to take evasive action to avoid a collision. A similar event happened on xxx with only me in the car at about 45 mph. The front brakes applied on their own in a similar way. I also recall a possible similar event in November or xxx. I am not certain of that earliest date. Since then, it has happened several times more and confirmed by Chevrolet dealership. Warning symptoms: the tire pressure monitoring system warning light has been on intermittently. The right front tire pressure does not display. The light was on before the March event and is on now. Dealer inspection: the dealer inspected the car on xxx and on later visits. A gm corporate field engineer also inspected the car. They stated they could not duplicate the concern and made no repair. I have since returned the vehicle to the dealership and it has been in their possession since xxx. The vehicle was taken out and confirmed the braking issue. Tech's reinspected the vehicle and cannot figure out the issue. The vehicle is available for inspection upon request. Safety risk: uncommanded hard braking at highway speed creates risk of being struck from behind and risk of loss of control.

Brake system failure, esc shutdown, speed-limited limp mode.
Normal driving conditions while in z-mode in moderate traffic, an audible bang was heard, however there was no immediate issue. A few minutes later the check engine light, abs, traction control and other lights appear on dash. Once lights appear, brakes fail and no longer slow the car down, the gas pedal only revved the car and could no longer accelerate. The car was still on and “driving”, I just didn’t have acceleration or brakes. I put my turn signal on and eventually was able to safely pull off the road and stop the vehicle utilizing neutral and the emergency parking brake. I was in genuine fear of crashing due to not having brakes or acceleration and felt that if the parking brake and/or neutral failed, then I’d have to crash to stop the vehicle. Not having brakes or acceleration put myself, my passenger, and every vehicle around me when it occurred at risk of injury. This has occurred twice in less than 1 year of ownership with this vehicle and I’ve taken it to two dealerships, mike reichenbach Chevrolet and rick hendrick Chevrolet. When it first occurred in December 2023, I was also in z-mode in light traffic, after it occurred, I drove slowly to the dealership with the hazard lights on. The second time I brought it to a dealership was after the first dealership couldn’t find the cause nor replicate the issue. The codes were cleared by the first dealership, but the car was still operating roughly and not as designed. The third time, in July 2024, it was brought to rick hendrick Chevrolet where the service invoice says “good possibility the aftermarket gps unit plugged into the dlc port is shorting out the vehicle communication circuits and causing intermittent electrical issues. May be also causing battery drain issue. ” the device referred to is called bouncie, I got it after this first occurred and the service team there is blaming both of these occurrences on the device. No repair was performed as the issue couldn’t be replicated.
When drive slowly, sometimes it grinds really lound when the wheels are wet or dry. Took it to 2 different dealers, they said it's normal. I have video for both incidents.
