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.
The contact owns a 2019 Chevrolet Corvette. The contact stated while driving 45 mph, there was an intense vibration throughout the vehicle. The contact stated no warning light was illuminated. The vehicle was taken to the local dealer coastal Chevrolet Cadillac Nissan (8519 ocean hwy suite 1, pawleys island, SC 29585, (843) 894-008) where it was diagnosed with needing the four wheels needing to be replaced. The vehicle was not repaired. The manufacturer was informed of failure. The manufacturer stated that the vehicle was not under warranty. The failure mileage was approximately 2,200.
When taking the car out for a test ride I noticed the tire pressure light was on. Dealer said it was because of the weather. I purchased the car and a few days had passed and the light was still active. I took it back to the dealer numerous times to rectify the situation. After numerous attempts the service department inspected further and realized my wheel was bent and cracked. After some research I had found numerous complaints about the C-7 Corvettes, specifically the grand sport and Z06 models where this happens all the time due to the wheels not being forged.

I purchased my vehicle in October of 2019. On, or about January 4, 2021, my right rear wheel started to lose air. I assumed that the tire needed to be repaired or replaced. I took my vehicle to a tire shop and they could not find anything wrong with the tire. After further investigation, a hair-line crack was discovered in the wheel. There was no indication of an impact, or damage on the surface of the wheel ( on the inside the wheel nor the outside of the wheel). My car is under warranty, so I took the vehicle to nelson hall Chevrolet in meridian for replacement under warranty. I was informed by the service technician that she had to get approval from General Motors before they could replace the wheel on my vehicle. General Motors refused to replace the wheel on my vehicle. I called General Motors myself and filed a complaint and to appeal their decision not to replace my wheel. After repeated attempts, General Motors still refused to replace the wheel on my vehicle. I have a vehicle that is under warranty, that I can not enjoy because of General Motors' refusal to honor the warranty on my vehicle. Please note, that I have not been in an accident, nor is there any damage on the surface of the wheel. This is a factory or a design defect...I keep the vehicle in my garage.
I have less than 5000 miles on my 2019 Corvette ZO6 and because of a vibration I had my tires and rims checked for balancing. I found out the drivers front and both rear rims must be bent that was detected on the balancing machine. I have not hit any potholes and have been very careful as this is my dream car. Of course I'm very disappointed especially after reading several other owners with similar problems!
II noticed uneven and excessive tire wear so I took my 2019 Corvette grand sport in and the technician pointed out cracks in both rear wheels, at about 15,000 miles of normal driving. I had the tires replaced and a 4 wheel alignment. Afterwards the tires would not maintain air pressure so I had to replace the wheels.
Gaining a lot of attention over the last several years by C7 (2014-2019) Chevrolet Corvette owners, is the issue of wheel rims cracking, specifically on the Z06 and grand sport models. I have been reading a lot of articles regarding this issue and while not currently experiencing the issue with my 2019 Corvette, I'm concerned that I will eventually experience the problem. I would like to know whether or not the nhts commission will be looking into this problem. GM has already stated that this issue is not related to defective equipment.
The wheel on my 2019 grand sport has two cracks in the rim that leaks air. The car has 11600 miles and is driven carefully this seems to be a current problem for GM for grand sport and Z06 model trims
Took Corvette to threeway Chevrolet in bakersfield on 6/9/20 for alignment and was told that all four trims are bent and cracked. And even though it has bumper to bumper warranty, they won't cover the trims. I have since spoken with the manager of threeway, and he agreed that it is a manufacturer defect and should be covered. He said, no way someone could bend and crack all 4 times, and not cause alot of damage to car, and airbags would deploy. Can you help me please.
I was driving my 2019 Chevrolet grand sport Corvette in my neighborhood, in October 2020. My tire pressure warning light came on. I was able to determine my right rear tire pressure had dropped precariously. I have run flat Michelin tires and was able to drive home safely. I inflated my tire to 30lbs psi and parked it in my garage. The next day I checked my tire pressure of all 4 tires and once again my right rear tire was low. It would not hold air. I called criswell Chevrolet where I purchased my car. They asked if I could drive my car to their facility in Maryland. I live in new jersy and I didnt feel safe driving my car under the circumstances to them. The service department was very familiar with the cracked / bent wheel issue affecting C7 grand sport and Z06 Corvettes. I was advised to go to a local Chevrolet dealership and have them inspect my wheels. I took it to global Chevrolet in North plainfield, N.J.. upon inspection, they determined I had a cracked right rear wheel and it needed to be replaced.. I did /do not abuse my car.
Took wheels and tires to a tire shop to have the wheels reconditioned after the same shop had scratched them during installation of new tires. Manager has advised me that the wheel reconditioning shop has told him that all four wheels are bent and will have to be trued before they are repainted. Reconditioning shop told him that they sees it a lot with Corvette wheels. Less then 10K miles on the car.
Found two cracks in rear oem wheel causing loss of air pressure. Was driving the car to get new tires as I thought I had an issue with a tire. Apparently thousands of late model grand sport and 06 Corvettes with this same issue
On 12/28/2020 I found that there was only 3 pounds of pressure in the right rear tire. Discount tire found a crack on the inside edge of the rim that was leaking air. They said there was no indication of impact or damage to the tire or the rim.

The wheels that came with the 2019 C7 ZR1 -4 wheels bent multiple times making the car unable to balance all 4 wheels. This makes the car vibrate. I bought a second set of oem wheels with the same issue happening. The dealer would not cover this issue. My dealer purchased wheel package also denied my claim. The car can not be driven without extreme vibrations. There was no significant incident the car just slowly began to vibrate and the wheels could not be balanced correctly because of wobble in the wheels. Two sets of wheels.
I have a problem with the oem wheels on my 2019 Corvette Z06 bending/warping/cracking under normal driving conditions. I have spent money having the wheels "straightened". I paid to replace one wheel that was cracked and lost air pressure. I contacted Chevrolet/GM about the problem. They indicate that it is a road hazard issue. I could believe this if it was only 1 or 2 wheels, but not all 4. this is the subject of at least one class action lawsuit. I see reports of wheels losing air pressure. Apparently a bent wheel can fatigue and crack causing loss of tire pressure. The symptoms of the bent wheel appear as road noise and are not obvious to the everyday driver.
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.
