general problems of the 2016 Chevrolet Corvette

Right rear rim cracked for the third time on my car. I noticed a slow leak after driving for about an hour earlier in the day. I get back in my car after a round of golf and notice that the right rear tire is low on air pressure. This is the third time I've had a cracked rim. I don't abuse my car, as this is a limited edition c7r, one of 500 made for the us market. My dealer admits that the rims are defective but says they can't do anything about it because gm says the rims aren't defective. Even though my car is only five years old with less than 36,000 miles on it, gm no longer makes these rims and none are available nationwide, so I'm forced to go to a aluminum wheel repair shop to get my rim fixed as there is no alternative. The original rim cracked, the $1,000 oem replacement rim cracked (in the same place), and now the original rim repaired has cracked (again in the same area just next to where it was repaired).

My 2016 Corvette with 13000 + miles has been in the shop with the � service rear axle light � on despite several attempts to fix it. After several trips to the service department they have been unsuccessful. This past week, I was notified by (service supervisor) that they have exhausted all efforts in the attempt to fix my car. I now have to wait for an engineer to be dispatched physically to look into this issue . According to service supervisor , this can take several weeks. I have looked at the internet and have found several Corvette owners having/ experiencing the same problem. Is gm looking into this ? does gm know what the problem is so they can share it here locally ? why cant my local dealership fix my problem despite working with gm engineers? what are my options? this light seems to come on on first starts or after being off for hours.
