Failure was the right rear wheel cracked in two places causing tire to go flat on highway . A flat tire could cause the vehicle to go out of control in traffic resultion in a serious accident causing injury or death Dealer Bob Huff Chevolet of Wrythville Va diagnosed and confirmed the problem and initially Walmart tire and service attempted to diagnose and fix the tire thinking a nail had beenj picked up causing a air leak but discovered the cracked wheel in two places causing air loss wrs . A new wheel was ordered by Bob Huff Chevy and installed by them. GM is well aware of the cracked wheels and refuse to do anything about it calling the bad wheels a result of road hazards and potholes etc. …
Prior to warranty expiration I took my car to be checked for vibration at highway speed. McMulkin Chevrolet NH told me they had to change the fluid in the transmission. This did nothing for the problem. During this time the drivers side tires would lose tire pressure faster than what is acceptable. At no time did the dealer mention the wheel cracking and warping problem experienced by this model vehicle. A year later I am experiencing excessive air leakage on three wheels. Upon further inspection I have found that the three tires have stress cracks. If I had known about the wheel defect I would have taken action sooner. I find this to be a dangerous safety related policy by GM to not alert the owners of these vehicles to the widespread problem.
Purchased the vehicle February 2018. In September 2019, I replaced the tires and within a few days, I started losing air pressure. Both rear wheels cracked. I tried to get GM to honor the 36 month bumper to bumper warranty but they refused. I purchased replacement wheels at my own expense. In June 2022, after 9000 miles, the car started driving rough so I brought it to the dealership. Both the driver side wheels, front and back, are bent.
Vehicle had a shake, and felt like it was shifting wrong. Apparently, Two of the four rims have were confirmed cracked which led to an unsafe vehicle for travel. The vehicle had approximately 15,230 miles on the tires and rims when air was leaking out. All four tires were shot. All four tires and all four rims had to be replaced.
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.
Drove approx 800 mi on interstate roads. Parked car for 2 days, started car lo tire pressure light 23#. Did not drive it, waiting to take to Chevy dealer next morning as we were planning our return 800 mi trip back home. Low tire pressure warning now at 20#, right rear passenger tire. Go to hendrick Chevy, charleston sc, approx 1 mi from hotel. They come back and tell us nothing wrong w/ tire, the inside of the rim is cracked. Less than 5500 miles on 2018 gs; black rims. Ordered new rim to be shipped in. Bringing damaged rim back to in to show to dealer where we purchased car from, ed martin Chevrolet, anderson, in. To the best of our knowledge we did not hit any potholes or road debris on the drive down. Low tire pressure light did not come on at any time during the 2 days of driving the 800 mile trip from in to sc. …
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. …
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. …
07/08/19 ' I took the vehicle to coggin Chevrolet at 10,053 miles for a problem right rear tire going flat. They could find no problem. 09/17/19 ' took vehicle to tires plus in ponte vedra fl to analyze why passenger side rear tire is losing air at a rapid pace. It lost 34 lbs. Of air in 10 days. They advised that the wheel was cracked. 09/19/19 - I just received a call at 3:18 p.m. From melanie vergotz, service advisor, coggin Chevrolet. She says GM refuses to fix the wheels (there are now 2 with cracks and are bent, (the right front and rear). GM claims the damage is a result of impact. That's what I figured they would say. I told the service advisor that she should inform the service manager that they are telling me I must drive an unsafe vehicle. I have never, never, hit a pothole or any road condition that would cause these wheels to be damaged.
I have owned the car since new when it was purchased in the spring of 2019. Since this time, I have driven the car approximately 11000 issue free miles. As of 2 weeks ago, I had all four tires replaced at a Chevy dealership. A few days after, I noted that there was a slow tire pressure leak in the rear passenger side tire. Upon taking it to the dealership today to have it looked at, it was discovered that there were 2 large cracks in that wheel, causing the leak. Because of this, we inspected the remaining 3 wheels to find that the other rear wheel also had a crack. There has never been any impact to the wheels (potholes, debris impact, etc.), that would have ever indicated to me to check for damage. This appears to be a workmanship issue from Chevrolet that could have severe safety implications if it were to tail catastrophically at speed.
