I am very disappointed that I took my car in 4 times and was told there was nothing wrong. I finally told them that I was not leaving until my car was checked out. All they did was drive it, I asked for it to be put on their machines to see if it read any codes, sure enough my transmission had to be rebuilt!!! I am even more upset that my transmission only lasted 2 years!!!!!! I thought I did good buying a american made vehicle, next time I buy I know it will not be a GM product!!!!!!!!
