2020 Chevrolet Corvette Owner Complaints

WHILE DRIVING THE 2020 CORVETTE AT A LOW SPEED, THE FRONT HOOD FLEW OPEN AND IMPAIRED MY VISIBILITY. THIS IS CHEVROLET'S FIRST ATTEMPT AT A MID-ENGINE CAR. SO THE FRONT HOOD IS ACTUALLY A TRUCK. THEY FAILED TO ENGINEER THE APPROPRIATE SAFETY LATCH FEATURES INTO THE HOOD THAT WOULD PREVENT THIS FROM HAPPENING. HOODS ARE REQUIRED TO HAVE A SECONDARY LATCH THAT MUST BE PHYSICALLY OPERATED TO OPEN COMPLETELY. *TR

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 "FRUNK" HOOD COMPLETELY BLOCKED MY VISION OF THE ROADWAY AND DAMAGE WAS DONE TO THE HINGES, HOOD AND FENDER ON THE DRIVER'S SIDE. *TR

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.

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.

WHILE DRIVING AT A PRUDENT SPEED THE HOOD OF MY VEHICLE OPENED WITH SOME DAMAGE TO THE HOOD(SPRUNG HINGES) AND BODY DAMAGE. I GOT A SIGNAL THAT THE HOOD WAS OPEN AND THEN THE HOOD SPRUNG OPEN. I WAS DRIVING AT 35-40 MPH AT THE TIME AND CAME TO A STOP IN A PRUDENT MANNER.(NO VISIBILITY)

I JUST GOT MY 2020 CORVETTE DELIVERED LAST WEEK. I AM THE FIRST OWNER OF THE CAR AND TODAY I WAS DRIVING UP PCH TOWARDS MALIBU. WENT UP TO 80-90 MPH AT TIMES. DROVE FOR ABOUT 100 MILES. I STOPPED TO GET SOMETHING TO EAT. GOT BACK IN MY CAR AND PROCEEDED UP THE CANYONS FOR SOME SPIRITED DRIVING. THE CAR IS ALREADY BROKEN IN AT 1300 MILES. I DECIDED TO PULL OFF THE ROAD TO TAKE SOME PICTURES OF THE CAR. I PUT THE CAR IN PARK WITH THE PARKING BRAKE ON AND LEFT THE ENGINE RUNNING WITH THE KEY FOB IN THE CUPHOLDER. AFTER I GOT THE SHOTS I WANTED, I PROCEEDED TO DRIVE DOWN THE CANYON AND WITHIN 15 SECONDS I HEARD THE FRONT HOOD LATCH CLICK/THUMP (SAME SOUND YOU HEAR WHEN YOU PRESS THE BUTTON TO POP THE HOOD) RIGHT BEFORE I SAW THE HOOD FLY UP AND HEARD A SNAP. SUDDEN LOSS OF VISIBILITY ALMOST CAUSED MY CAR TO GO OFF THE CLIFF AS I COULDN'T SEE THE TURN. LUCKILY I WAS ABLE TO STOP THE CAR BEFORE GOING OFF THE ROAD. THE HOOD DID NOT HIT MY FRONT WINDSHIELD, BUT THERE IS SEVERE HINGE DAMAGE AS WELL AS DAMAGE TO BOTH FENDERS AND THE FRONT HOOD. I HAD MY WINDOWS DOWN AND MY ROOF OFF, DID NOT HAVE THE RADIO ON AND IT WAS QUIET ROAD. THERE WERE NO WARNING LIGHTS THAT THE HOOD LATCH WAS OPEN/DISENGAGED. EVEN WHEN THE HOOD FLEW UP, THERE WAS NO INDICATOR LIGHT OR BEEPING. I PUT THE HOOD BACK DOWN AS CAREFULLY AS I COULD.I HAD NO CHOICE BUT TO TRY MY BEST TO CLOSE THE HOOD SINCE I WAS IN AN AREA WITH NO RECEPTION IN ORDER TO KEEP DRIVING. IN THE CLOSED POSITION, THE HOOD IS NOW ABOUT 3/4 TO 1 INCH LOWER THAN EACH FENDER. SUPER PARANOID I TRIED TO DRIVE AS SLOWLY AS I CAN HOME, BUT I DID REACH SPEED UP TO 55 MPH. THANKFULLY IT DID NOT HAPPEN AGAIN. GM SPOKESPERSON BLAMES IT ON USER ERROR. I GUARANTEE YOU GUYS THIS IS NOT USER ERROR

THIS COMPLAINT IS A RESULT OF GM NON ACTION TO THEIR RECALL A202307260. IT HAS BEEN 2 MONTHS SINCE THE RECALL HAS BEEN ANNOUNCED AND PARTS OR NOT AVAILABLE. LOSS THE THE AFFECTED ITEM (BRAKE BOOSTER) SEVERELY IMPACTS SAFETY THAT COULD CAUSE AN ACCIDENT RESULTING IN SEVERE INJURIES OR DEATH. GM HAS PARTS -- THEY ARE BUILDING 180 UNITS PER DAY. THERE ARE UNDER 700 - 2020 CORVETTE CARS AFFECTED BY THIS RECALL. GM IS PUTTING PROFIT AND SALES AHEAD OF SAFETY. NHTSA SHOULD REQUIRE GM TO IMMEDIATELY USE PRODUCTION PARTS TO REMEDY THIS ISSUE AND CLOSE THIS RECALL CONSIDERING IT IS SAFETY RELATED.

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.

THE FRONT TRUNK LID (THE LID) OPENED AT A SPEED OF ABOUT 40MPH ON A CITY STREET. THE WARNING LIGHT WAS NOT LITE PRIOR TO THIS INCIDENT AND NOTHING ACTIVATED THE LID DOOR SWITCH. THIS INCIDENT BENT THE LID HINGES AND DIS-ALIGNED THE LID RESULTING IN THE DAMAGING OF THE CORNERS OF THE QUARTER PANELS. I HAVE NOW TAPED DOWN THE LID IN FRONT TO PREVENT THIS OCCURRING AGAIN. I HAVE NOTIFIED MY CHEVY DEALER OF THIS INCIDENT AND WILL BE REPLACING THE HINGES AND REPAIR THE QUARTER PANELS.

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'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.

THE FRONT DRIVER SIDE DAYTIME DRIVING LIGHT WHICH IS ALSO THE TURN SIGNAL DOES NOT WORK. IT HASN'T WORKED FOR ALMOST 3 MONTHS AND CHEVY DOES NOT STOCK ANY HEADLIGHTS FOR THIS CAR. THIS HAS BEEN GOING ON FOR WAY TOO LONG AND I DON'T THINK THAT THEIR STATEMENT SEEMS ACCURATE ABOUT DRIVING WITHOUT THE LIGHT/TURN SIGNAL. EVEN THOUGH GM STATES IT OK TO DRIVE I FEEL IT'S NOT THAT SAFE AND HAVE NOT DRIVEN IT MUCH THESE PAST 3 MONTHS. THIS IS A NEW MODEL AND I KNOW IT'S DIFFICULT TO HAVE ALL PARTS AVAILABLE FOR A NEW CAR BUT A HEADLIGHT SHOULD BE SOMETHING THAT IS IN STOCK IN THEIR WAREHOUSE PRIOR TO SHIPPING THESE CARS TO THE PUBLIC.

THERE IS A STRONG SMELL OF GASOLINE IN THE TRUNK. THE SMELL IS STRONGER WHEN THE GAS TANK IS RECENTLY FILLED OR FULL.

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)
