General Motors

I took my 2014 Chevrolet Corvette to Knapp Chevrolet. There was a noise or grinding when you push on the gas peddle when traveling 30-45 mph. The first day i took it in was July 5. They said they fixed it and i picked up the car, and it was not fixed. Since then I have taken into Knapp 8 times, and they basically had the car for 4 months. It is still not fixed. They Service Manager JP was handling the repair and tried different things to get the car fixed. He hears the noise and thinks it is fixed. At this point I will take it to Auto Nation on 45 S. when I purchased the car. And see if they can find the problem. I dont like being with out my car for 4 months
