What 2020 Chevrolet Corvette owners say
Body & structure
The 2020 Chevrolet Corvette is truly a unique looking automobile and it attracts attention everywhere you go. Almost everybody wants to look at it. On 04/30/2020, I was at a local shopping center and several people were admiring the car and looking at it. The vehicle was sitting stationary in a parking space, the engine was running and the vehicle was in park. When the people had finished admiring the car, I got into it and proceeded to the exit. From the exit, I turned onto the main road (a us designated hwy) and accelerated. When I reached a speed of approximately 25 to 30 MPH, the front hood (also called a frunk), flew up and completely blocked my vision of the roadway. I was able to successfully brake and pull to the shoulder of the highway without further incident. …
The hood popped open while driving damaging the car. Fortunately there were no other cars around and I was able to safely pull over. I was driving at 43mph when the hood flew open blocking my vision and damaging the car. I have video of the incident from the performance data recorder in the car. The hood had not been opened at all the day this occurred and I had driven on multiple other roads including the highway without incident. The car had just over 1400 miles on it at the time of the incident.
Transmission & drivetrain
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. …
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
Engine & cooling
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.
Received 2020 Corvette on 9/15/20, on 9/24/20 went to use the car to do to doctor. The car started and then would not run.

Car has been gone 10 days so far and do not have all of the valve springs to repair car. Car only has 115 miles on it. Luckily the car was in the garage when this happened.
