I purchased a 2016 Chevrolet Colorado Z71 4x4 with the Duramax Diesel. On the way home from the dealership I hit a bump and the door locks started going up and down it shifted down and the check engine light came on. They reset the code and it still has the issue when you hit a small bump. They they replaced the computer and still is having the same issue. I purchased on 5/26 and only had the vehicle of 1 1/2 days...does anyone else having the same issue?
