2018 CHEVROLET CORVETTE Complaints

AFTER DRIVING THE VEHICLE FROM KENTUCKY TO FLORIDA THE FOLLOWING DAY I RECIEVED AN ALERT ON MY PHONE SAYING MY RIGHT FRONT TIRE WAS FLAT. AFTER EXAMINING THE TIRE AND WHEEL I DISCOVERED A SIGNIFICANT CRACK ON THE INBOARD SIDE OF THE RIM. I TOOK THE VEHICLE TO DALE EARNHARDT JR CHEVROLET IN TALLAHASSEE FL. AFTER INSPECTING THE WHEEL THEY WOULD NOT COVER THE DAMAGE AS A DEFECTIVE WHEEL. I'VE OWNED THIS VEHICLE ALMOST 2 YEARS AND HAS 15,000 MILES. THIS WILL BE THE 2ND WHEEL THAT HAS CRACKED AND AND 3 THAT HAS BENT. GM REFUSED TO COVER ANY OF THEM. THE FIRST WHEEL BENT WITHIN 500 MILES OF PURCHASE, THE DEALER BOUGHT THAT REPLACEMENT WHEEL. I PURCHASED AN EXTRA WHEEL AND TIRE WARRANTY AFTER THAT AND THEY PAID FOR 2 BENT AND I CRACKED WHEEL. I BELIEVE THEY TOO NOW KNOW THESE Z06/GRAND SPORT WHEELS ARE DEFECTIVE AND ARE REFUSING TO PAY FOR THIS CURRENTLY CRACKED WHEEL. THIS RIM WAS CRACKED DURING MY DRIVE FROM KENTUCKY TO FLORIDA CAUSING THE FLAT TIRE. ONE DAY THIS ISSUE IS GOING TO CAUSE SOMEONE TO HAVE AN ACCIDENT AND GM WON'T DO ANYTHING ABOUT IT.

REAR OEM WHEELS OF HAVE LIP CRACKS AND CHEVROLET WILL NOT HONOR NEW RIMS UNDER THE FULL FACTORY WARRANTY. THEY HAVE STATED THAT THE RIMS HAVE DEVELOPED CRACKS FROM HITTING POT HOLES. THIS IS NOT CORRECT BECAUSE I HAVE NOT HIT ANY "POTHOLES" OR ANY OTHER ROAD IMPERFECTIONS THAT WOULD CAUSE ALL OF THESE LIP CRACKS. THERE ARE HUNDREDS OF THE SAME COMPLAINTS. THIS SEEMS TO BE AN ONGOING ISSUE WITH THE WHEELS THAT ARE ON THE GRAND SPORT MODEL. THREE DEALERSHIPS HAVE TOLD ME THAT I NEED TO BUY NEW RIMS AT THOUSANDS OF DOLLARS. I PAID $55,000 FOR A CAR THAT SHOULD NOT NEED NEW RIMS. THE ISSUE IS THAT IF I BUY NEW OEM RIMS, MANY OTHER CORVETTE OWNERS HAVE DONE THIS AND THE SAME CRACKS APPEAR ON THE NEW REPLACEMENT WHEELS. THIS IS JUST WRONG AND CHEVROLET KNOWS THEY HAVE A PROBLEM YET FAIL TO TAKE OWNERSHIP. VERY DISAPPOINTING AND FRUSTRATING TO SAY THE LEAST. BOTH WHEELS LOST AIR PRESSURE AND ONE WENT COMPLETELY FLAT. VERY DANGEROUS TO DRIVE OF DEFECTIVE WHEELS ARE EXPRESSWAY SPEEDS. I WENT TO MANY SHOPS TO GET THEM REPAIRED AND NO-ONE WILL EVEN TOUCH THEM!

BOTH REAR RIMS (WHEELS) CRACKED, RESULTING IN REPEATED LOSS OF TIRE PRESSURE. DISCOVERED AT 13,500 MILES, STILL UNDER BUMPER TO BUMPER WARRANTY, GM DECLINES WARRANTY COVERAGE STATING IT MUST HAVE OCCURRED FROM A ROAD HAZARD. CORVETTE FORUMS DISCUSS MULTIPLE 2018 GRAND SPORTS WITH SIMILAR CRACKED RIMS. DOCUMENTATION FROM DEALER AVAILABLE ON REQUEST.

I JUST PURCHASED THE VEHICLE 11-04-2019. THE TRUNK POPS OPEN WHEN I GET IN THE CAR AND SIT DOWN. THERE IS ALSO A PROBLEM WHEN BACKING UP TO PULL OFF AND TURNING TO THE LEFT OR RIGHT, THE CAR WILL START JERKING AND THERE'S A POPPING SOUND.

WHILE GETTING NEW TIRES INSTALLED, THE TECHNICIAN NOTICED ONE OF MY WHEELS WAS CRACKED. I HAD NOT HIT ANY POTHOLES OR ANYTHING THAT WOULD CAUSE MAJOR STRESS TO THE WHEEL. IF I HAD NOT NEEDED NEW TIRES, THE CRACK LIKELY WOULDN'T HAVE BEEN FOUND UNTIL IT CATASTROPHICALLY FAILED.

MY 2018 CORVETTE ZO6 UPON INSPECTION OF THE TIRE LOSING AIR, DEALERSHIP FOUND BOTH RIGHT SIDE WHEELS TO BE BENT..THESES ARE CHROME ALUMINUM WHEELS WITH 6,513 MILES ON THE CAR. DATE OF SERVICE WAS JUN 4, 2019. I PAYED TO HAVE THEM REPAIRED.. NEXT TIME, ON SEPT. 17, 2019, TIRE WAS LOSING AIR. THIS TIME THE DEALERSHIP FOUND THE RIM TO BE CRACKED..I THEN HAD TO PAY FOR A NEW RIM. DEALERSHIP DOESN'T STAND BEHIND THERE CUSTOMERS AND NEITHER DOES GM. ABSOLUTELY A PROBLEM IN THE MANUFACTURING.. THAT HAPPENED WITH ONLY 8716 MILES ON MY CAR..

TL* THE CONTACT OWNS A 2018 CHEVROLET CORVETTE EQUIPPED WITH MICHELIN PILOT SUPERSPORT TIRES, SIZE: P285/30Z/R19 94Y (NA) FOR THE FRONT (DOT NUMBER: 4MLW) AND SIZE: 335/25Z 20 (NA) FOR THE REAR (DOT NUMBER: 4M2R). WHILE DRIVING 45 MPH, THERE WAS A VIOLENT VIBRATION IN ALL FOUR TIRES WITHOUT WARNING. THE CONTACT NOTICED THAT THE THREAD WAS SEPARATING FROM EACH TIRE. THE VEHICLE WAS TAKEN TO ROGER DEAN CHEVROLET (101 SW PINE ISLAND RD, CAPE CORAL, FL 33991, (239) 574-3326) TWO DAYS PRIOR TO THE FAILURE, BUT NO FAILURE WAS FOUND AT THAT TIME. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE VEHICLE AND TIRE FAILURE MILEAGE WAS APPROXIMATELY 11,748.

AT APPROXIMATELY 5700 MILES ON OCTOBER 10, 2019, INFLATE TIRE ALERT CAME ON INDICATING THERE WAS ONLY 17 LBS OF AIR IN DRIVER'S REAR TIRE. THIS WAS A DROP OF 13LBS PRESSURE IN 2 DAYS. UPON INSPECTION AT LOCAL TIRE SHOP, IT WAS REVEALED THAT THE LEFT (DRIVER'S) REAR WHEEL HAD TWO CRACKS NEAR HE TIRE BEAD SEALING AREA ON THE INNER SIDE OF THE WHEEL, ALLOWING AIR TO SLOWLY LEAK OUT OF THE TIRE.

VEHICLE WAS AT HIGHWAY SPEED WHEN DASH INDICATOR SHOWED THAT THE PASSENGER REAR TIRE WAS RAPIDLY LOSING AIR PRESSURE. CAR WAS TAKEN TO THE LOCAL CHEVROLET DEALERSHIP WHERE THEIR TECHNICIAN DISCOVERED THAT THE PASSENGER REAR WHEEL WAS CRACKED. THE CRACK WAS NOT DUE TO STRIKING ROAD DEBRIS OR A POTHOLE. THE VEHICLE HAS NOT BEEN IN AN ACCIDENT. THE DEALER REFUSED TO ACKNOWLEDGE THAT THE COST OF A REPLACEMENT WHEEL SHOULD HAVE BEEN COVERED AS PART OF THE VEHICLE WARRANTY BECAUSE OF A MANUFACTURER'S DEFECT.

9-23-19 WAS TOLD BY DISCOUNT TIRES THAT MY REAR WHEEL IS BENT, AND THERE IS CRACK ON ONE OF THE FRONT WHEEL. CAR IS ONLY 9200 MILES. AND GM WON'T COVER IT UNDER THEIR BUMPER TO BUMPER WARRANTY.
