Navigational (global Positioning System) Gps problems of the 2023 Chevrolet Corvette

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.
