Within that volume, owners reported 0 crashes, 0 fires, 0 injuries, and 0 fatalities.

Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2020 CORVETTE is structure:body with 10 filings, followed by visibility/wiper (4) and unknown or other (4). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 4 active recall campaigns, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.
NHTSA currently has 57 investigation files overlapping the 2020 CORVETTE, and 2 remain open. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration. Use the related-complaint feed below to read raw owner narratives before deciding whether any pattern here affects your specific use case.

We have a water leak that was coming in both windows and onto the floor. Since reported it the car will slow down while driving because of codes issues about the doors are not closed and it is. I feel it's due to the water leak that is coming into the car. Took the car to a Chevrolet Dealer in Columbia South Carolina and they said it was coming from the roof weather stripping. They said it wasn't a recall for the 2020 C8 Corvette corvette yet. Also called GM Customer care to see if I can get some help to get it fixed. No luck.

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

Periodically the Instrument Cluster(Speed, Tach and other gauges) goes black. When this happens you have know knowledge of any information about the vehicle speed, etc.. This lasts a variety length of times, but no longer that about 1minute. The instrument cluster then reappears, but usually will go out again in a few minutes. A message appears, "Service Instrument Cluster'" This will happens 4 or 5 times in a period of around 10 minutes then it will never happen again the rest of the current drive. This may not happen again for a couple of months of driving then it does it again.
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. Th

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.
2020 CHEVROLET CORVETTE STINGRAY. CONSUMER WRITES IN REGARD TO RUSTING SHOCK TOWER HOUSING.
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.

GM REFUSES TO REPLACE THE BRAKE MODULE DESPITE THE FACT THAT THIS HAS BEEN KNOWN SINCE SEPTEMBER 2020. THE REMEDY "IS INCOMPLETE"AND PARTS ARE NOT YET AVAILABLE. IT IS LUDICROUS TO ASSUME THAT PARTS ON A CURRENTLY PRODUCED CAR ARE NOT AVAILABLE. THEY ARE INSTALLING THIS MODULE DAILY. THESE ARE BRAKES THAT CAN FAIL AND CAN CAUSE AN ACCIDENT WHEN THEY DO FAIL.

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.
