What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2018 Chevrolet Corvette, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

From owner reports, verbatim
Wheels on these cars commonly crack and break online. Mine have a visible crack in one of them and is losing air due to quality of wheel from Chevrolet
Inside lip of rear wheel cracked and wheel bent beyond repair, per wheel repair company. OEM make and model tire was in place and no noticeable impact was felt to cause this failure. This caused an air leak leaving me stranded at the side of the highway. Had to buy an expensive replacement wheel.
Brakes
Reports naming service brakes, the antilock braking system, brake hoses, master cylinders or the parking brake.
From owner reports, verbatim
THE BRAKES HAVE NOW FOUR TIMES FAILED TO STOP THE VEHICLE. WHEN PRESSED THEY GET HARD, THEN GO DOWN TO THE FLOOR AND THERE'S A PULSATING FEELING. THE VEHICLE JUST CONTINUES TO GO TO THE FLOOR. ON THE THIRD OCCASION THAT IT HAPPENED, THE VEHICLE IN A NON-EMERGENCY SITUATION, WOULD NOT STOP IN TRAFFIC AND REAR-ENDED ANOTHER VEHICLE. IT IS DANGEROUS AND GM IS NO HELP.
TWO BRAKE ROTORS ON 2018 CORVETTE GRAND SPORT HAVE PERMANENT RUST BANDS THAT DO NOT WEAR OFF UNDER BRAKING. THEY ARE SCORING AND GROOVING THE BRAKE PADS INSTEAD. GM BLAMES THE DEALER FOR POOR MAINTENANCE BUT NEITHER WILL REPLACE BECAUSE THEY SAY IT'S ONLY 'COSMETIC' ACCORDING TO THEM. THEY DID ADVISE ME TO REPLACE THE ROTORS MYSELF AT A COST OF $4000 ON A BRAND NEW CAR! IT HAS HAD THE BAND SINCE DAY 1! WHEN THE CAR IS WASHED OR THE ROTOR GETS WET IT FUSES TO THE PADS AND LOCKS THE WHEEL. YOU HAVE TO ROCK THE CAR GET IT TO BREAK LOOSE. THEY KEEP REFERENCING A GM SERVICE BULLETIN THAT PROHIBITS DEALERS FROM REPLACING OR RESURFACING RUSTED ROTORS. THIS IS NOT NORMAL SURFACE RUST. IT IS PERMANENT AND IS COMPROMISING THE BRAKE PADS! THIS IS DEFINITELY A SAFETY CONCERN.

I ATTENDED A TWO-DAY NCM TRACK EVENT AT VIR IN JUNE 2019. DURING THE SECOND SESSION ON DAY TWO MY 2018 Z06 HAD A POWER STEERING ISSUE. WITHOUT ANY WARNING, I FELT AND HEARD A LOUD THUMP THROUGH THE STEERING WHEEL AS I APPROACHED TURN 3 FROM NO-NAME, I HAD VERY LITTLE STEERING ABILITY THAT REQUIRED HEAVY HANDED INPUT ON THE STEERING WHEEL CAUSING ME TO LIFT AND BRAKE TO KEEP THE CAR FROM RUNNING OFF THE TRACK. THEN I RECEIVED A DIC MESSAGE ON THE DASH TO 'SERVICE POWER STEERING GEAR.' I COME IN TO LET THE CAR COOL DOWN AND WENT BACK OUT LATER WITH NO ISSUES BUT WAS NOT RUNNING HAS HARD AS BEFORE. THIS POWER STEERING OVERHEATING ISSUE IS VERY CONCERNING WHEN ON THE TRACK APPROACHING A TURN GOING 70 TO 80 MPH. THE OUTSIDE TEMP WAS 90 DEGREES AND THE COOLING SYSTEM WAS RUNNING AROUND 240 DEGREES. THERE IS A GM PRELIMINARY INFORMATION ABOUT REDUCTION IN STEERING ASSIST WHILE DRIVING ON THE TRACK DURING HOT DAYS. BULLETIN NO.: PI1535B DATE: NOV-2017 THAT REQUIRES TO INSTALL A NEW POWER STEERING GEAR COOLING DUCT FOR 2014-2018 CHEVROLET CORVETTE.
