2020 CHEVROLET CORVETTE Complaints and Recall Information

SERVICE BRAKES

General Motors LLC (GM) is recalling certain 2020 Chevrolet Corvette and Cadillac CT4, CT5 and XT4, 2021 Chevrolet Trailblazer, and 2020-2021 Buick Encore GX vehicles. Sensor connection contamination in the electronic brake boost system may cause an interruption of communication between the sensor and the brake boost system.

Risk: If communication with the sensor is interrupted, the electronic brake boost assist could be lost. Extra pedal force will be required to slow and stop the vehicle, increasing the risk of a crash.

SEAT BELTS:FRONT:RETRACTOR

General Motors LLC (GM) is recalling certain 2020 Chevrolet Corvette vehicles. The driver's seat belt retractor may not lock as intended during a crash.

Risk: In the event of a crash, if the driver's seat belt fails to lock, there is an increased risk of injury.

LATCHES/LOCKS/LINKAGES:TRUNK LID:LOCK

General Motors LLC (GM) is recalling certain 2020 Chevrolet Corvette vehicles. The release button located inside the front trunk compartment may not function after the vehicle has been shut off for ten minutes. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 401, "Internal Trunk Release."

Risk: If a person climbs inside the front trunk compartment and closes the lid, they may be trapped inside, increasing the risk of injury.

ELECTRICAL SYSTEM

The contact's son owns a 2020 Chevrolet Corvette. The contact stated that while her son was driving 65 MPH, the oil temperature and check engine warning lights illuminated; however, the driver was able to safely drive to the destination. Upon leaving and attempting to start the vehicle, the vehicle failed to start. The vehicle was towed to the dealer, who diagnosed a failure with the main wiring harness. The vehicle was not repaired. The contact was informed that the replacement part was on a national backorder. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 40,000.

SUSPENSION

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)
