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. Thank you, [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

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.

The rear right wheel is confirmed having two cracks by Fremont of Chevrolet. The car was not driven in any conditions beyond that would be considered "normal". We found out about this issue as the TPMS would indicate low tire pressure after the car would be sitting for a few days on the rear right tire. Driving on a cracked wheel presents a danger as the crack can expand and fully deflate the tire during normal driving. This is a known issue for GM for having fragile wheels on the grand sport and Z06 models

Left front wheel was found to be out of round (bent), when trying to balance the wheel assembly due to vibration. The wheel was straightened, and the vibration was resolved. Left rear tire lost pressure while driving on open road in Wyoming. Managed to get to Les Schwab tire store. They removed the wheel/tire assembly, submerged in water tank and found the air leaking through the cracked wheel. Dash warning light had come on indicating the loss of pressure. Local GM dealer (Whistler Chevrolet) was able to order a replacement wheel and it was installed the next day. The expense of the new wheel and mounting was in excess of $900.

A "low tire pressure" alert shown on my dashboard referring to rear left tire. This car has 17,000 miles since new, and new tires less then 90 days before. I added correct air pressure, parked car in garage, 3 days later same notice, tire low on air. First removed left rear, cleaned and inspected and noticed approximately 1" crack along the rim. Check with water and found leak. Repeated for right side, a crack which is currently not leaking air. Photos of both rims ae attached

the wheels crack / bend won't hold air in normal driving

I purchased my vehicle in December of 2017. Around December 2019, my left 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 or even on the outside of the wheel and they are not bent or scratched anywhere on the rim. My car was still under warranty, so I took the vehicle to my local dealership and 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. My vehicle is no longer under warranty and two additional wheels now have the same issue, one will no longer hold any air. I cannot drive my vehicle until my rims are replaced. I ordered a new set for $3K at my expense. Please note, that I have not been in an accident, nor is there any damage on the surface of the wheel. There must be a manufacturing or design defect...I keep the vehicle in my garage, it's pampered and gets driven less than 7K miles per year in sunny Florida where there are no pot holes or terrible road conditions; everything is flat and smooth. I became aware that there are thousands of complaints of this exact issue while reading the Corvette forum for these rims. There is potentially a horrible risk to someones life is this issue isn't corrected for some unknowing victim. Please investigate the issue with these rims and force GM to issue a safety recal for this safety issue. I believe that there are thousands of unsuspecting drivers that have the same issue with thier vehicle that are unaware of this deadly safety hazard. Please help Corvette owners driving safety, even if GM refuses to do so!

I drive my corvette about 3000 miles per year, no highway, never in the rain. I took my GS in for new tires and was informed the driver side rear wheel was cracked and leaking air. I have never hit a bump, drove it on a track, drove on deflated tires etc. Makes no sense the rim would be cracked.

- Oakland Park, FL, USA

My rear rims cracked mulitple times. I had gotten them fixed but got tired of fixing them and accumulated around 5-8 cracks in total for my rear rims.

March of 2019: I had unexpected flat tires, one front and one rear. There was no warning nor reason to suspect any damage. Took the car to the shop and had cracked wheels. As most Corvette owners, I pamper this car and would know/remember hitting anything. I replaced the wheels at my expense after getting no help from the Chevrolet dealer. The attached photo shows there was no impact- just a big crack. December 2021: I have one unexpected rear flat tire. Found another crack. Unexpected flat tires without warning is an obvious safety concern for me and anyone around me as I drive. After looking on the internet, there are 100's of complaints about this and multiple class-action lawsuits. This should be forced to be a recall and the government should step in. I am surprised that this has reached this point, as a risk analysis engineer. The field complaints have reached a point where the occurrence rate and the severity of the failure should flag action. Earlier in my career, I designed and tested wheels as a tier 1 supplier to GM. I know how GM Tire and Wheel operate. There are specs for impact and fatigue testing and I bet the poor design is very well understood. I hope you can help.

This is a common problem with the OEM wheels bent that precludes proper and unsafe use. Tire inflation and balance along with vibrations are a major safety concern. I would like GM to do a recall on these wheels and help the owners for replacements with a forged aluminum wheel as opposed to the engineering mistakes made using a cast alluminum wheel.
