2019 Chevrolet Corvette

I HAD BEEN FEELING VIBRATIONS WHILE DRIVING AFTER ONLY A FEW MONTH OF OWNERSHIP. I TOOK CAR TO DEALER FOR SERVICE ON 26JULY2019 (6369 MILES) AND WAS TOLD IT WAS BRAKE ROTORS, WHICH WERE TURNED. THE PROBLEM DID NOT GO AWAY. I TOOK IT IN AGAIN ON 25JAN2020 (12811 M) AND ON 12FEB2020 (13700 M). DEALER REPLACED BRAKE ROTORS BUT SMALL VIBRATIONS DID NOT GO AWAY. ON 17FEB2020 (13928 M), I HAD TIRES REPLACED IN AN ATTEMPT TO RESOLVE VIBRATIONS. VIBRATIONS BECAME STRONGER OVER TIME. ON 4NOV2020 (20678 M) I TOOK CAR TO DISCOUNT TIRE AND HAD WHEELS BALANCED. I WAS TOLD ALL FOUR WHEELS ARE OUT OF ROUND BUT R/R IS THE WORST BENT AT .025 AND THE L/R IS ALSO BENT AND CRACKED. THIS IS A HIGH PERFORMANCE VEHICLE THAT I DO NOT RACE OR MISTREAT. THE WHEELS SHOULD DEFINITELY BE STRONG ENOUGH FOR STREET USE WITHOUT RISK OF BENDING OR BREAKING. I NOW HAVE UNSAFE WHEELS ON A HIGH PERFORMANCE VEHICLE.

ALL FOUR RIMS ARE BENT AND CRACKED. THIS IS TRUE FOR ALMOST ALL 2015 TO 2019 GRAND SPORT AND Z06 CORVETTE'S. THERE ARE MULTIPLE CLASS ACTION LAWSUITS FILED AGAINST GMC AS OF TODAY'S DATE. THE RIMS ARE DEFECTIVE AND GMC KNOWS THEY ARE. BUT REFUSES TO FIX THEM. I PAID OVER 50,000 CASH FOR MY 2019 GRAND SPORT, AND IT SITS IN THE GARAGE WITH 2 FLAT TIRES. DON'T WANT TO DRIVE IT AT OF FEAR SOMETHING MAY HAPPEN. I HAVE SPOKEN WITH GMC SEVERAL TIMES, THEY REFUSE TO HELP. CAN YOU PLEASE HELP ME?

UPON RECEIVING MY 2019 GRAND SPORT FROM THE DEALER BY TRUCKING COMPANY, ALL 4 WHEELS WERE WARPED/BENT. I REALIZED THIS WHEN I WENT TO DRIVE IT FOR THE FIRST TIME AND AROUND 50 MPH THE CAR STARTED TO SHIMMY/SHAKE. I TOOK IT TO MY LOCAL CHEVROLET DEALER AND THEY PUT IT UP ON THE RACK AND SHOWED ME ALL 4 WHEELS WHERE SPINNING WARPED. I HAVE VIDEOS OF ALL 4 WHEELS.

IN LESS THAN TWO YEARS, THIS VEHICLE HAS HAD TWO CRACKED RIMS AND FOUR BENT RIMS. IN RESEARCHING THE ISSUE ONLINE, I HAVE FOUND THAT THIS IS A MAJOR PROBLEM, PRIMARILY FOR 2014-2019 CORVETTE GRAND SPORT AND Z06 OWNERS HAVE WITH THE ALUMINUM-ALLOY WHEELS. A CRACKED WHEEL POSES A SAFETY RISK AS IT COULD PUNCTURE A TIRE WHILE DRIVING. GM HAS DONE NOTHING TO STAND BY THEIR PRODUCT, ALTHOUGH THESE CARS HAVE A BUMPER TO BUMPER WARRANTY. THERE ARE CLASS ACTION SUITS THAT HAVE BEEN FILED. THERE HAS BEEN NO SPECIFIC INCIDENT THAT ATTRIBUTE TO MY RIMS HAVING THESE PROBLEMS. IT IS NOT AN EVERDAY CAR FOR ME AND I SELDOM DRIVE IT.

BOTH REAR WHEELS ON MY 2019 CORVETTE GRAND SPORT ARE CRACKED. ONE WHEEL HAD A CRACK REPAIRED AT AROUND 24,000 MILES BEFORE I PURCHASED IT IN JANUARY 2020. IN AUGUST 2020 AT ABOUT 28,500 MILES, ONE REAR TIRE STARTED LOSING PRESSURE. UPON INSPECTION, THE WHEEL WAS FOUND TO BE CRACKED IN TWO PLACES. IT CRACKED AT THE SAME SPOT WHERE IT WAS REPAIRED AND AT A DIFFERENT LOCATION. THE OTHER REAR WHEEL WAS HOLDING AIR, BUT WAS FOUND TO BE CRACKED AS WELL. THAT WHEEL WAS NEVER REPAIRED BEFORE. THERE WAS NO ACCIDENT AND NO POT HOLES OR ROAD HAZARDS HIT TO CREATE THESE CRACKS. I DRIVE THE SAME WELL MAINTAINED ROADS THAT I DROVE MY 2006 CORVETTE ON FOR 120,000 MILES WITHOUT IT EVER CRACKING A WHEEL. BOTH REAR WHEELS CRACKED IN THE 4,500 MILES THAT I HAVE DRIVEN THE CAR. THIS REPRESENTS A SAFETY HAZARD. AS OF TODAY, I WAS INFORMED THAT CHEVROLET ONLY OFFERS THE SAME CAST ALUMINUM WHEEL THAT HUNDREDS OF OTHERS HAVE ALSO REPORTED CRACKING OR BENDING AS A REPLACEMENT.

MY 2019 CORVETTE GRAND SPORT HAS HAD ISSUES WITH THE RIMS FROM DAY ONE. CURRENTLY THERE IS LES THAN 10,000 MILES. EACH RIM HAS BENT & NOW WE HAVE A CRACKED RIM (ABOUT 1 1/2 INCH LONG). THE FIRST TIME THIS HAPPENED WE HAD ONLY DRIVE THE CAR ABOUT 500 & WAS TOLD WE HAD 2 BENT RIMS. THIS HAPPENED THE FOLLOWING YEAR AND AGAIN THIS YEAR. BUT THIS TIME WE HAVE A 1 1/2 INCH CRACK ON THE RIM. WHEN WE DISCUSS THIS WITH THE DEALERSHIP WE WERE TOLD THAT GM WOULD NOT COVER ANY COSTS RELATED TO THE RIMS. THESE CAST RIMS ARE VERY WEAK, WHICH COULD CAUSE A LIFE THREATING ACCIDENT. THANKFULLY, IT HASN'T HAPPENED TO US. BUT I HAVE NOW SPENT ALMOST $1000 TO FIX THEM. SINCE THIS WILL OCCUR EVERY YEAR THAT I DRIVE IT. I MOST LIKELY WILL HAVE TO BUY NEW RIMS AT A COST OF ABOUT $1,250 PER RIM. CONSIDERING THE COST OF ANY CORVETTE YOU WOULD THINK THAT GM WOULD EITHER COVER THE COST TO REPLACE. OR WOULD HAVE PROVIDED FORGED RIMS FOR A VEHICLE OF THIS TYPE AS PART OF THE CORVETTE. I WOULD THINK THAT GM WOULD HAVE CONSIDERED THE SAFETY FEATURE ON A PERFORMANCE VEHICLE AND PROVIDED A MUCH STRONGER RIM.

MY 2019 CORVETTE WAS PURCHASED ON SEPTEMBER 20, 2018. I DROVE HOME THINKING I WOULDN'T HAVE ANY REPAIR OR REPLACEMENT PROBLEMS FOR SOME TIME ON THIS NEW CAR. A FEW DAYS LATER, AS I'M READING THE OWNER'S MANUAL, THERE ARE ABOUT FOUR OR FIVE PLACES IN THIS THICK MANUAL THAT SAYS MY TIRES ARE "SUMMER ONLY" TIRES, AND THAT IT COULD BE HAZARDOUS TO DRIVE ON THESE TIRE IN COLD OR WET WEATHER. WELL, SUMMER ENDED ONLY ABOUT 2-3 DAYS AFTER I PURCHASED THE CAR, SO I IMMEDIATELY FELT UNSAFE DRIVING ON THE SUMMER ONLY TIRES. I WENT TO MY TIRE STORE AND BOUGHT A SET OF ALL-WEATHER TIRES. SEE UPLOADED PHOTO 0973. I THINK IT IS UNREASONABLE FOR ALL NEW CORVETTES TO ONLY COME WITH SUMMER ONLY TIRES! NONE OF THE DEALERS I NEGOTIATED WITH FOR THIS CAR WOULD DELIVER MY CAR WITH ALL SEASON TIRES! LATER, RELATED TO MY COMPLAINT NUMBER 11364386 PERTAINING TO CORVETTE RIM DEFICIENCIES, I HAD TO PREMATURELY REPLACE EACH OF THE FOUR NEW ALL SEASON TIRES, ONE BY ONE, DUE TO RIM PROBLEMS CAUSING TIRE IRREGULARITIES WHERE THE TIRES MEETS THE RIMS. THERE WAS LOTS OF TREAD LEFT, BUT DAMAGE TO EACH OF THESE TIRES WHERE THEY CONTACTED THE OUT OF ROUND RIMS.

I BEGAN HAVING RIM PROBLEMS SHORTLY AFTER PURCHASING MY 2019 CORVETTE IN SEPTEMBER 2018. THE CAR HAD A VIBRATION AND MY TIRE STORE SHOWED ME HOW ONE OF THE WHEELS WAS OUT OF ROUND, SO I ORDERED A NEW RIM. SEE UPLOADED PHOTO 0948. MY NEXT PROBLEM WITH VIBRATION OCCURRED WITH THREE OF THE RIMS BEING OUT OF ROUND, SO I TOOK IT TO A WHEEL REPAIR SHOP TO HAVE THEM STRAIGHTENED. SEE UPLOADED PHOTO 0949. LATER ON, VIBRATION CROPPED UP AGAIN, AND I HAD ONE OF THOSE THREE WHEEL AGAIN STRAIGHTENED, PLUS WELDED IN TWO PLACES TO REPAIR AIR LEAKING CRACKS IN THE RIM, SO THE RIM WOULD HOLD AIR. SEE UPLOADED PHOTO 0950. STILL LATER, THAT RIM BEGAN LEAKING AIR AGAIN, SO I HAD THE TIRE SHOP AGAIN STRAIGHTEN AND WELD THE LEAKING CRACK. SEE UPLOADED PHOTO 0969. STILL LATER, ANOTHER RIM WOULD NOT HOLD ANY AIR PRESSURE FOR LONGER THAN ABOUT FOUR HOURS, SO AGAIN THAT RIM WENT TO THE REPAIR SHOP TO BE WELDED. SEE UPLOADED PHOTO 0972. IN SUMMARY, IT SEEMS LIKELY THESE CORVETTE RIMS, WHICH COME WITH LOW PROFILE TIRES, ARE SUBJECT TO LOADS WHICH A CASTING CANNOT ABSORB WHEN ROLLING OVER POTHOLES, SPEEDBUMPS, AND OTHER ROAD ANOMALIES. WITH A NORMAL PROFILE TIRE, THIS WOULD UNLIKELY TO BE A PROBLEM, BUT WITH LOW PROFILE TIRES, THE RIMS ARE ONLY TWO INCHES FROM ANY ROAD ANOMALY. THEREFORE, THE CORVETTE RIMS SHOULD PROBABLY BE MANUFACTURED USING A FORGING PROCESS, RATHER THAN A CASTING PROCESS. OR, THE CORVETTES SHOULD BE DESIGNED TO USE NORMAL PROFILE TIRES INSTEAD OF LOW PROFILE TIRES.
