The contact owned a 2020 Chevrolet Corvette. The contact stated that while driving at an undisclosed speed, the contact came to a complete stop at a stop sign. The contact stated that the light turned green, the accelerator pedal was depressed, and the vehicle started jerking with a rumbling sound coming from the engine compartment. In addition, the engine independently shut off, however the transmission failed to properly shift, pressure level at zero, check engine light, idle creeping disabled, and service transmission warning lights illuminated. The contact stated that he restated the vehicle and the failure reoccurred, and the contact turned the vehicle off. The contact turned off and restarted the vehicle eleven times however, the failure persisted. The contact was able to restart the vehicle and drove to the residence.

The vehicle was sold to the dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 7,200.

I had a complete transmission failure while on a road trip over July 4th. I just read that GM was doing a recall on the Transmission Control Module but it does not include my car, which is what failed on my car at 19,000 miles. My trip was interrupted, we spent two days paying for hotel & rental car in Springfield, MO and now my car is fixed with new TCU in Springfield, but I live in DFW area. If my car had a recall I would have had it fixed before our trip and this all could have been avoided. Now I have to figure out how to get my car back home.

CAR IS EQUIPPED WITH REMOTE START. ON APRIL 20TH I PARKED IN THE GARAGE, PUT GROCERIES AWAY INCLUDING SOME THAT WENT IN THE FRIDGE IN THE GARAGE. THE CORVETTE KEYS WERE IN MY POCKET. I SET A TIMER FOR ONE HOUR FOR ITEMS I HAD PUT IN THE GARAGE FREEZER TO CHILL. WHEN I WENT BACK AT THE ONE HOUR ALARM, THE VEHICLE WAS RUNNING IN THE CLOSED GARAGE. TO USE REMOTE START THE VEHICLE HAS TO BE LOCKED FIRST AND I NEVER LOCK THE VEHICLE IN A CLOSED GARAGE. CHANCE MOTION OF THOSE KEYS IN MY POCKET HAD LOCKED THE VEHICLE AND INITIATED REMOTE ENGINE START. I HAD JUST LAID DOWN TO NAP WHEN THE ONE HOUR ALARM WENT OFF. I SHUDDER TO THINK WHAT WOULD HAVE HAPPENED HAD I NOT USED MY ALARM FOR THOSE FOOD ITEMS.

ON SEPTEMBER 24, 2020, CHEVROLET ISSUED A RECALL FOR A POSSIBLE CONTAMINATED BRAKE BOOSTER MODULE ON NUMEROUS 2020 VEHICLES. THIS TO ME IS A SERIOUS MATTER WHEN IT DEALS WITH THE VEHICLES BRAKING SYSTEM. THERE HAVE BEEN CUSTOMERS ONLINE WHO HAVE TALKED ABOUT THIS ISSUE, WITH ONE CUSTOMER STATED THAT HIS BRAKES DID FAIL AND IT WAS DIFFICULT FOR HIM TO STOP. I HAVE MADE NUMEROUS CALLS TO GM AND NO ONE COULD GIVE ME ANY ACCURATE INFORMATION. I HAVE NOT BEEN DRIVING MY NEW 2020 CORVETTE VERY OFTEN BECAUSE OF FEAR OF BRAKE FAILURE. I WAS TOLD BY A GM REP THAT IF MODULE DID GO OUT THAT YOUR BRAKES WOULD STILL WORK. HE STATED THAT YOU WOULD JUST HAVE TO USE MORE FOOT PRESSURE ON BRAKES. IT HAS NOW BEEN OVER 90 DAYS AND I AM REQUESTING THAT THIS ISSUE GET RESOLVED FOR ALL NEW CAR OWNERS WHO HAVE THIS RECALL. GM IS TOO LARGE OF A COMPANY TO LET THIS JUST LINGER AS IF ITS NO BIG DEAL.
