2017-2019 Corvette grand sport has a high number of report instances of rims cracking and bending that forum members feel is not normal, not due to hitting potholes or anything. I had never hit any potholes or anything hard, and while having my tires changed, the shop shows me a crack in the rim. On the blog site "Corvette forum", there's numerous people and pictures of people showing their cracked or bent rims. GM is telling people this is normal wear and tear and not dealing with it. This is not normal. Several people have reported multiple tires bent or cracked. Please investigate. I'm sure GM does not have accurate data, people most people report the dealer turns their claim away as not being covered, so it's not getting fully reported. This appears to be a problem only with the grand sport model.

GM is putting defective wheels on grand sport and Z06 Corvettes. These wheels will not withstand normal driving on any highway. The issue is that these wheels bend on impact, be it expansion joints along bridges or small imperfections in the roadway that other cars handle every day. The issue is that GM says these are road hazards and they are not responsible. The wheels were not engineered to take normal driving on roads anywhere. This started in June after a trip I took and the car picked up a vibration. Took it to S dealer and he said the wheels were bent and not covered under warranty and would sell me new ones 2 front wheels for about $1800. I then took the car home and took the front wheels off and had them straightened at a cost of $110 each. I thought that took care of the problem so we drove the car on another trip to nova scotia, Canada. We were on a trip and lost air in the left front tire ( picture below ) it had worn all the way down through all the belts due to the wheels being bent again. See all 3 pictures. These wheels are a safety hazard for these cars to use on public highways as they develop cracks and cause severe tire wear in short periods of time. I had another set of brand new wheels at home. I had to come back home and get them and take them back to Canada to get my car home. On the 1700 mile trip back the car developed a vibration and when I took it back to my tire dealer he said that the right front wheel was bent. The big issue is GM does not track these issues if you do not buy the new wheels from them and it goes unreported. A friend of mine who has less than 5000 miles on his 2019 needs to buy 4 wheels and 4 tires and the dealer even told us there were 2 people the week before that had bent rims on I-71.

Had 3 of the 4 rims bend, per the dealer diagnosis, for no apparent reason. Car had 2,000 miles on it. It seems to be a systemic problem. There are multiple posts about this issue, along with the wheels cracking for no reason, at the following internet forum; https://www.corvetteforum.com/forums/C7-general-discussion-142/ in my instance the car drove fine the evening before (I'd actually picked it up from the dealer the same day as they repaired another issue). Got in the car the next morning to go to work and noticed the bad vibration. I thought a wheel weight had fallen off. Took it to the dealer and after diagnosis they informed me that 3 of the 4 rims were bent (both passenger side and driver rear).

Left front and left rear wheels bent after very minor defect in highway, had to replace wheels

Both left wheels on my 2017 grand sport bent in normal driving over normal roads. In researching the issue, this seems to be a recurring problem with the stock wheels on 2017-2018 Corvette grand sports and 2015-18 Corvette Z06S. GM agreed to replace the front wheel, but the dealer didn't realize the rear was also bent (no visible damage to either wheel, the wheels are just not strong enough). GM is now claiming they won't fix/replace the rear wheel. Car vibrates because of the bent wheel.
