Gm has got one of the biggest pain in the butt computer operating systems going for the cobalts. Check engine light comes on goes off. Rpm's go to 500 and up to 1200, anything 100 km for speed the car vibrates like crazy. Doors unlock and lock without warning. Car is really hard to control when windy. Changing rear brakes is a nightmare. Some times car starts and stops right away. There is a very loud and annoying ticking sound near the back. It happens when stopped, driving, and even when car is turned off. With the new clean drive testing these cars are going to fail do to check engine light if its on they will not test.
