2018 Chevrolet Corvette owner complaints

I started feeling vibrations in dec 2018, took it to a local dealership and the dealership told me that one of my rims is bent...took it to another dealership june 2019 and that dealership confirmed that the rims were cracked...finally july 2020 I purchased four new tires and that's when it was discovered that my two front rims are bent and the two rear rims have cracks in them. Gm will not replace the defective rims, so I ended up purchasing new rims.

Rear OEM wheels of have lip cracks and Chevrolet will not honor new rims under the full factory warranty. They have stated that the rims have developed cracks from hitting pot holes. This is not correct because I have not hit any "potholes" or any other road imperfections that would cause all of these lip cracks. There are hundreds of the same complaints. This seems to be an ongoing issue with the wheels that are on the grand sport model. Three dealerships have told me that I need to buy new rims at thousands of dollars. I paid $55,000 for a car that should not need new rims. The issue is that if I buy new OEM rims, many other corvette owners have done this and the same cracks appear on the new replacement wheels. This is just wrong and Chevrolet knows they have a problem yet fail
