Wheels cracked. Letting air leak out

- Wes Bend , WI, USA

The left rear wheel of this vehicle has two major cracks in it. The tire has had a slow leak for the past couple of months as indicated by the low-tire warning light on the dashboard. I took it to a Discount Tire Outlet in an effort to find and repair the leak, and upon inspection the technician found the two cracks and pointed them out to me. Obviously, if the tire were to blow out at any speed it would endanger the lives of me and any of my passengers, as well as the people in other vehicles around me. The vehicle manufacturer, General Motors, is very well aware of this problem as it has received a number of lawsuits over this specific issue. To date, General Motors has refused to replace these defective wheels, or to provide any other type of relief to Corvette owners.

Left rear tire was going flat regularly.I took it to the tire store and they said all parts of tire were ok but the Wheel was Cracked. The first warning I had was Dec 29,2020 and then Dec 20,2021-It had been examine by dealers and nothing was said. It began regularly Dec 9,2023 and will go down between 2 days and 2 weeks since. I took it into Folsom Chevrolet on March 5 and they said the tires were ok, but nothing about the wheel. I took it to tire America on March 23 and they found the wheel crack.

My right rear tire developed a slow leak, losing approximately 2 pounds per day. I added air to the tire until I had the opportunity to go to my local Chevrolet dealer, Rick Hendrick Chevy. They inspected the wheels and tires. They found cracks in both rear and the right front wheels. I have read about this situation for several years and had hoped I wasn't going to have this problem. This situation is widespread throughout all seventh generation (C7) Z06 and Grand Sport Corvettes. I know that Chevy dealers are instructed to say they have no knowledge of this issue there are hundreds of cases reported in The Corvette Forum. Several owners sought arbitration through the Better Business Bureau and won. Chevrolet is still blaming drivers for the wheel problems and they refuse to pay for the repairs. The estimate I received on Saturday, February, 3rd, 2024 is $6,226. It's no coincidence that Chevy decided to install forged wheels instead of the cast wheels that are involved in this. If you have the opportunity, have GM provide you with sales numbers for the wheels for the C7 Z06 and Grand Sport. I'm sure you will see a significant difference between those part numbers and those for the Stingray models. Although many owners are buying forged wheels from aftermarket sources in order to avoid the cracking problem again. As far as GM claiming this is a rare occurrence, I ask you read an article in the 2024 edition of "Corvette Magazine 2024 buyers guide on page 99 titled Real World Buy". The article states "As most are aware, GM let down many Grand Sport and Z06 owners. Both wheel designs crack too easily. Usually on the inner rim where there is no support for the 12 inch tunnel". I believe that this issue deserves some investigation by your department. Thank you for your time

On 11/29/2023 I brought my 2017 Chevy Corvette Grand Sport to my local Chevrolet Dealer (Maritime Chevrolet in Fairfield, Connecticut) because both rear tires were rapidly losing air (brand new tires had just been installed 4 days prior by this same dealership). Upon inspection, the dealership discovered multiple cracks in both rear wheels causing the tires to lose air. The service manager told me he looked into the issue and discovered multiple bulletins regarding this problem and said that General Motors is aware of the faulty wheels, however they are not willing pick up the cost on replacing the defective wheels or offer a safe alternative. The dealership wants to replace the 2 cracked wheels for $900 each (and even offered the pay for half the cost). The replacement wheels are the exact same as the defective ones and will likely crack again. This is an incredible safety hazard and I am now fearful to drive this car that only has 13,000 miles on it. I have owned the car since new and have never abused it and it is driven very little. If the tires lose enough pressure while driving it could possibly lead to an serious accident. After further research online, this is a well known defect and safety issue that has been documented by many different sources. Hundreds, if not thousands of owners have complained of this exact same safety issue, and I believe there is a class action lawsuit in regards to it, although I am not sure where that stands. If you have any questions, please contact me anytime to discuss.

I was driving when the tire pressure warning light came on indicating the rear drivers side tire pressure dropped to 17 psi. I immediate drove to a gas station to add air. I inspected the tire and didn-??t notice any damage. I aired the tire up to 32 psi and drove off. Within 3-5 mins the warning came back on. Upon further inspection of the inside of the wheel I noticed that the rim now had a 1.5 inch crack that went from the edge of the rim into the barrel of the wheel.

When I replaced my tires with new ones on my 17 corvette Z06. My mechanic found all four rims bent. I know this is a big issue with these rims. I hope you people act on this issue with Chevrolet before someone gets hurt or killed

Wheel on passenger rear is cracked and leaking air constantly. Discount Tire said to report it as GM said too bad. It seems that all of my friends with this model car are having the same issue. Worthless wheel now as it will not hold air. It caused me to partially lose control of the car since it had too low a pressure.

Upon tire replacement an inspection of the right rear wheel has shown inside wheel lip cracks in 2 places as well as an out of round condition. There has been no associated tire damage with this defect.

Passenger side rear wheel developed a crack causing an air leak. Defect was acknowledged and wheel was replaced under a purchased extended warranty specific for tires and wheels. I purchased this warranty specifically due to the common complaint of cracked wheels on this model line (Chevrolet Corvette Grand Sport), built between 2017 - 2019. With the slow leak, this damaged wheel did not present itself immediately. I drove the vehicle for an undetermined amount of miles, but it is safe to assume at least 3k miles as I would add air to the effected tire/wheel multiple times assuming it was due to ambient air temperature changes. A mechanically defective wheel could prove to disastrous and lfe threatening at highway speeds should a catastrophic failure occur. Approx. mileage was 22k miles on vehicle. Only error was the TPMS "Low Pressure" Warning.

Cracked and warped wheel issue! I already replaced two wheels in last 3 years and yet I got two more wheels cracked. And one of them is the replaced wheel. I cannot remember the time I dealt with warped wheel. Probably more than 10 times. I have only used Chevrolet official dealers for any service. Everything is already in records. My car is only at 30K miles. This is insane that GM is not taking ownership of this issue and resolve it. I cannot believe that the class action law suite is not fully finalized yet. I am ready support the existing law suite with any of the data that I have.

In may of 2020 I went to get new tire for this vehicle, the installer noticed i had a right rear cracked wheel. So I purchased a new wheel from GM, and had it installed, the wheel was about $800. The next spring, 2021, I took the car out of storage and noticed both rear wheels were very low on air pressure, both were at about 5 LBS each. So I inspected the wheels and found that both were cracked. I kept the old wheel that was cracked and decided to have all 3 welded by a professional shop. One of those wheels was cracked by the time I put the car back in storage in October, so I exchanged it with the other welded wheel I had on hand. The crack on this wheel propagated from a different area then the weld repair spot. All three rear wheels have cracked, two of them twice in different area. Now I believe I have another one cracked. I am going to replace these wheels with an aftermarket forged wheel. I did not have these inspected by anyone other then the national chain tire shop. Low tire pressure warnings were the reason I inspected the wheels. According to a few car websites, this is a reocuring problem with wheels on Z06 and Grand Sport Corvette models. Yes this is a safety problem.

Hello, I recently purchased my 2017 Corvette Z06 and had a GM dealership complete a complete inspection prior to taking delivery. Less than 1 month later the car developed a vibration which an independent tire shop diagnosed as one (1) cracked front wheel and one (1) bent rear wheel resulting in the vibration. I have driven less than 1k miles since inspection/purchase and the vehicle only has 29k miles total. These are the factory GM wheels which must now be replaced. I was not aware of the GM Corvette Wheel issue prior to this happening but now understand this is a widespread, systemic issue.

The Two Rear Wheels were Cracked on the inside near the Tire Bead

- The Villages, FL, USA

On 1-24-2023 at 13,224 miles the rear left tire began to lose pressure slowly. Upon investigation the rear left wheel is cracked. This is unsafe as the rapid pressure loss or splitting of a wheel can happen at interstate speeds. This can cause an accident. The problem was confirmed by a tire service center. It has not been inspected by anyone other than myself and the tire center. The car TPMS warning displayed to alert the low pressure condition.

Tire rack in south bend indiana went to replace my corvettes tires and when they removed the rear wheels they identified two cracks. Due to safety policy's they could not remount my tires or pout new tires on the wheels... I was stuck so I called GM to discuss. GM opened a case for me and said that is all they could do at the time. I purchased new wheels to get the car back on the road and waited for GM to call. They never did so I called and the customer service lady set up an appointment at the nearest dealer to inspect the cracked wheels. I traveled to the the dealer for the appointment and of coarse they didn't know anything about the GM ticket and sent me away. I called GM again and set me up another appointment with a different dealer and assured me the issue would get resolved. I traveled to the 2nd dealer and they didn't know anything about the GM ticket and then said if they were to look at the wheels they would have to be mounted on the car. I left and GM called me the next day and the ladt informed me that my claim / ticket was denied and will be closed out. I asked how could you deny the claim when you never even looked or inspected them?! The wheels should not be on the road and this is an ongoing issue with the C7 Grand Sport's and Z06.

I had a rear right wheel leaking air. Figuring that i was a slow leak, I took it to my local Discount Tire shop for repair. The informed me that the tire was fine and that it was the rim that was leaking. As it turns out all but 1 of my factory GM wheels had cracks in them. After doing a litle research I've learned that this is a massive issue with the Corvette C7 factory wheels. The wheel have been bending, cracking and breaking. As of right now GM has not taken ownership of this dangerous issue. My understanding is that lawsuits are now pending.

Drivers side rear wheel has cracked causing air to leak. If left unnoticed, this may lead to catastrophic failure as the wheel may completely break a highway speeds.

- Perry Hall, MD, USA

Took the car to discount tire since the tire lost air (run flat tires). They removed the tire and the rear passenger side rim has one 3 inch and two additional cracks in the rim. No warning signs of this issue while driving at highway speeds earlier in the day. The large crack was leaking air. Rims are discontinued by Chevrolet and no replacements are available. Had to drive the car home which was an obvious safety issue. A large number of other drivers are faced with the same safety issue over these defective rims. I will add myself to any class action lawsuits over this issue so that no one is injured due to a total rim failure.
