Purchased the vehicle with 7944 miles, currently has around 11,000. One of the tires was leaking air so had an auto repair shop look at all the tires and rims. THREE of the rims are cracked. I am not driving the vehicle for safety reasons. It is not safe to drive with a cracked rim. I did not hit any road hazards or pot holes. The rims appear to be defective and after 11,000 miles should not have damage.

I had 2 rear 2019 Corvette grand sport oem wheels crack, and leak air requiring expensive replacement, I also have the other 2 original wheels now bent. The dealer in terryville ct was notified, but GM denied the claim - I still have these wheels for inspection driving on bent or cracked wheels is a hazard since they could fail at speeds - there is no warning or symptoms until the low air light comes

I purchased this 2019 corvette grand sport on 3/6/2023. After I had driven it a little over 300 miles the tire statred to lose air (got a low air pressure warning). Filled it with air and got another warning again. Took the wheel off the car and inspected tire and rim. Found a weld repair had been done with another crack in the rim that look like someone tried to repair that crack. No I'm stuck without a car to drive.

On 1/10/23 I visited discount tire at 520pm my driver side rear tire has had a slow leak for 2 days so I was getting the tire checked out. The tech called me over and showed me a crack on rim he sprayed with soapy water and it bubbled he said your tire is fine the leak is coming from your cracked wheel I called my local dealership and they stated they will get back with me. I have read hundreds of complaints on Corvette forums where owners are having the same issues.. GM selling defective wheels...... even a class action lawsuit still being settled.

I have 32,800 miles on my 2019 Corvette Grand Sport. Each year during my annual service, I have had to have wheels repaired that were bent. Today, during my regular service, both of my rear wheels were identified as cracked and must be replaced. Cracked wheels on the 2017 to 2019 Corvette Grand Sport and Z06 models is a significant safety issue and needs to be addressed by your organization. GM should be forced to replaced all of these poorly engineered wheels before someone is killed or injured in an accident when the wheels fail.

Rear Wheels cracked begot flat tire

My corvette developed a cracked wheel. We took it to the Dealership that put new tires on a week ago because the low air alarm came on. They informed me the wheel was cracked and denied damaging it when putting on the new tires. -€œIt just happens-€ was their claim. Now we learn there is a class action lawsuit because so many generation C7 Corvettes are suffering unexplainable wheel failures. GM is denying warranty claims and it-€™s costing the car owners thousands of dollars to replace wheels. The wheel I need is going to be $1200 and will likely be yet another OEM wheel prone to the same problem. Should this not be something in your agencies purview to investigate?

My factory wheel cracked in two places while traveling to the Corvettes at Carlisle event. I have a little over 18000 miles on my car at this point. I have taken great care of my car and have not hit and rough potholes or obstacles in the road. I have not -€œtracked-€ my car either. I have read about many other Corvette Z06 and Grand Sport owners who have suffered the same cracked and bent rim issues with the stock GM supplied wheels. Apparently the wheels are faulty as reported by hundreds of dissatisfied owners. The cracked wheels fail to hold air pressure causing a safety situation while driving at highway speeds. I understand that there is a current class action lawsuit in progress. I feel that GM should stand by their product and replace these inferior wheels with safer, more sturdy ones..especially for the price we paid for the vehicle. At this point, the consumers need the NHTSA to help us with this situation as GM has refused to accept any responsibility at this point. They blame the consumer-€™s driving habits as a reason for the issue-€¦.not the obvious faulting manufacturing of the wheel. I appreciate your attention to this matter and look forward to hearing your response. Sincerely, [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

2019 Corvette Grand Sport August 2021 - Driver side rear wheel cracked losing pressure rapidly making continued driving dangerous. Instructed by a local dealership to drive at minimum speed to the dealership to prevent the degradation and potential catastrophic failure of the wheel and/or tire. Drove to a local dealership where the wheel was inspected and confirmed to be cracked. Wheel was replaced with a new OEM GM Corvette wheel. January 2022 - Passenger side front wheel cracked losing pressure rapidly making continued driving dangerous. Immediately drove the vehicle home and parked it until I could confirm the problem. Have not driven it since and will being the process of replacement within the week (01/30/2022).

OEM wheels fail. Thousands of online reports of 2015-2019 Corvette C7 Grand Sport and Z06 models wheels cracking without incident. My wheel is available for inspection. Safety was risked by having a wheel crack, loose air pressure and fail under normal operating load, potentially causing a crash. This issue has been reported to GM, has countless incidents also reported and can be easily confirmed at any dealer. My vehicle is currently at the dealer and has been inspected by their professionals. No symptoms prior to failure. No other damage has been noted or reported by the dealership to this wheel or tire.

Vehicle has 6900 miles on it, started to vibrate badly while driving on highway. Car has not been in any accidents and carefully driven. Dealer says the two rear wheels are bent.This could lead to cracking of wheels and/or loss of control of the vehicle. Vehicle is still under 36 month/36,000 mile bumper to bumper warranty. GM will not cover cost to replace and assumes no responsibility.

- Lawrenceburg, IN, USA

The rim cracked from the outside edge and progressed until air begin to leak. The dealer will not replace the rim unless you bought a tire and rim policy. But the manufacture of the tire does warrantee the tire and the dealer knows that to be the case. So the dealer knows the rims are the problem. I have researched and many others have the very same problem with their Corvette rims cracking until air is lost. These rims are definitely improperly designed and they should be recalled.

In February 2021, my Chevy dealer service department found that both of my rear wheels were bent and had to be repaired. My Corvette had 13,319 miles on it and I had never run off road or hit a major pot hole to cause this level of damage. The service technician said that this was 'common' on 2017 to 2019 Corvette Grand Sport and Z06 OEM wheels. Additionally, the wheels would probably 'crack' in the future and need to be replaced. I find this totally unacceptable that GM (Chevy) would design and manufacture defective wheels on a sports car, or any of their vehicles.

Upon tire change, 3 cracks noted in right passenger wheel. Problem diagnosed at Discount Tire (1475 Austin Hwy, San Antonio, TX 78209) on 6/5/2021. No known obvious road hazards or incidents that could have explained wheel fractures. Due to severity of wheel cracks, it was not even safe to drive home from Discount Tire (per the technicians there). There was concern for eminent wheel failure that would risk loss of control of car and injury to self/others. Car was left there until new wheel can be ordered and shipped. Upon review of internet, this is a recurring problem owners of this model of Corvette have been reporting. There is concern for design issues, wheel selection, and tire selection leading to repeated wheel failures. More wheel failures are expected in the future raising concerns for potential safety risks.

I purchased new tires for my 2019 Corvette grand sport and when the tire shop removed my old tires I was informed that (3) of the wheels were cracked and (1) rear wheel was cracked in two places. I had no choice but to purchase a set of (4) new wheels with only 32,430 miles on the car.

Car was taken to a local dealer to have 4 new tires installed. Upon installation the dealer discovered both rear rims were cracked (1 could not hold air) and one front rim was bent. The dealer will not cover the wheels and my wheel insurance will not cover anything but oem parts. I secured forged wheels as I am concerned about my safety by replacing the same rims that came with the car. The car was stationary when the problem was discovered. I am afraid to drive the car with the oem wheels. GM is claiming driving behavior and/or potholes. I have been driving Corvettes on and off since 1986 and never had any cracked rims. In all that time my driving habits have not suddenly changed. Secondly, it is highly unlikely that I would have three defective rims all at the same time simply due to pot holes. After conducting research my strongest belief is that since the rim is cast and not forged it lacks the strength need for a performance vehicle and that the cracks are fatigue cracks which occur over time. Further, there is no sensor or warning system to let you know the cracks are present. In addition, the problem is magnified in that the cracks are on the inside of the rim and not visible when looking at the wheel. It is my belief that there will be fatalities attributable to this defect. I am uploading everything I sent to my insurer who informed me that they cannot cover after market wheels, even though they were less expensive. Ps: I cannot tell from your file upload if both files were loaded.
