2020 Chevrolet Corvette

My left rear axel/rear differential/ control arm snapped with normal driving and breaking. It is available for inspection. This mechanical failure made me loose control of my vehicle on the busy freeway and threw me across a lane into the freeway center divider. Nearly caused a pile up accident and killed me.. The dealership service department checked it in today. I filed a claim today with the manufacture but nobody looked at it yet. There were no warning lamps and i believe there is still no warning lamps

The dual clutch transmission on my 2020 C8 Corvette has a diagnostic code of p1955. This was determined after the service light on the vehicle illuminated and it was taken to service at the dealership. Other codes that stored included p0868 and p0869 which indicate low hydraulic pressure and high hydraulic pressure respectively. The p1955 code is an internal fault that requires complete replacement of the transmission according to GM service bulletins. This bulletin also advises that no repair attempts are to be made except for complete replacement. The vehicle has not shown any symptoms currently. Gears shift normally, there are no vibrations, etc. However, the dealership advised the transmission can go into limp mode, fail completely, or damage other components of the power train at any point. This issue is known to GM. They have investigated the matter since 2021 or earlier. There have been no recalls on the transmission despite the safety risks of sudden loss of power, being stranded, or catastrophic destructive failure without warning. These pose risks to occupants inside the vehicle and other vehicles or people on the road. My repeated questioning of this matter to the dealership and GM customer service have been ignored. They only advise the cost to replace is with the owner of the vehicle despite the root cause being at the level of engineering of the part. They are unwilling to admit this failure is at the level of a manufacturing/engineering defect as a financial cost mitigation strategy. The Issue with sudden failure of the transmission in these vehicles are widely known, investigated, and occurring at a high rate, especially in early model C8 Corvettes.

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 with the same defect. I then began noticing videos on YouTube exposing the problem and selling aftermarket strut covers (not OEM or from a dealership). This issue poses a significant safety hazard, as a strut could eventually fail due to corrosion. At high speeds of 70 mph on the interstate, this failure could potentially endanger the driver, passengers, and other motorists. However, the dealership and GM Customer Service continue to insist that it is a maintenance issue, despite it clearly being a design flaw. I voiced my concerns about the safety implications, but they offered no explanation or comment other than reiterating that it's a maintenance issue. I warned them that when someone dies as a result of this problem, they will eventually have to pay for the strut mounts and face additional lawsuits. They informed me that the conversation was being recorded, and I hope someone with authority will listen to it. It's not a matter of if, but when these strut mounts fail, endangering the safety and lives of others on the road. respectfully [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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 was informed that the valve body needed to be replaced. The vehicle was repaired under warranty. 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.

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.
