2020 CHEVROLET CORVETTE Power Train Problems

I replaced the battery in my C8 Corvette after three years of ownership. Upon removing the plastic cover from the frunk to access the battery, I discovered the two front strut mounts. To my dismay, I noticed excessive corrosion on both strut mounts, with the left side near an AC compressor line being considerably worse. I immediately took the car to the dealership, where they took pictures and agreed it was a design defect. They submitted a warranty claim to GM, which was denied multiple times. Despite having purchased an extended warranty when I bought the car, which still shows corrosion coverage until 2026 and over 100,000 miles, both the dealership and GM refused to repair my car. I explained that if my garage-kept car, which was never driven in the rain, had such severe corrosion at only 13,703 miles, one could only imagine the condition of a daily driver...

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 later towed to the dealer where it was diagnosed with a failed valve body. The contact...

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.

AT THE TIME OF INCIDENT THE VEHICLE HAD 660 MILES. MOST OF THE ACCUMULATED MILES ARE: 60% STREET AND 40% HIWAY. I WAS INSPECTING THE WHEELS AND TIRE WHEN I SPOTTED A SIGNIFICANT AMOUNT OF GREY/BLACK COLORED GREASE RANDOMLY COVERING THE INNER WHEEL. UPON FURTHER INSPECTION I NOTICED THAT THE GREASE WAS SPLATTERED ON THE EMERGENCY BRAKE UNIT, SENSORS AND WIRING HARNESS. THE GREASE WAS ISOLATED TO THE REAR PASSANGER AXLE. I SUSPECT THAT THE GREASE CAME FROM A DEFECTIVE CV BOOT. TOOK VEHICLE IN TO CHECKOUT THE PROBLEM AND THEY DETERMINED THE GREASE WAS FROM A DEFECTIVE CV BOOT. NEW AXLE WAS ORDERED.
