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.

While operating vehicle loses the ability to accelerate, which has resulted in 3 near miss collisions, (one head on incident and two side impact collisions.) the side impact near miss collisions were after making an attempt at a left turn where there was plenty of time initially to complete the maneuver, the car completely loses the ability to accelerate and is dead in its tracks on the road. The head on near miss collision occurred during an attempt to pass another vehicle. As the car accelerated in the passing zone, and pulled next to the vehicle being passed, the ability to accelerate was lost and thankfully the other driver was able to avoid the collision prior to the ability to accelerate resuming. When the ability to accelerate voids, pushing the gas pedal has no impact on acceleration. These 3 occurrences were the most pronounced and potentially fatal, however, there have been a myriad of instances where the ability to accelerate has stopped momentarily. I am also concerned with the overwhelming chemical odor (plastic smell) emanating throughout the car. After a year of ownership, and leaving windows open while stored, it persists to the point that it remains overwhelming with the windows up and top on. Due to fears for my safety and wellbeing I have been unable to take pleasure in the vehicle I purchased exclusively for enjoyment.
