What a horrible place. I took my car in with an ignition module issue, I was given a peice of wire from the mechanic that was burned and freyed. I was told that the wire was cut out of one of the wiring harnesses below my dash and that was the route of all my problems. They stated that it was fixed and charged me $700 for their time and a new ignition modual. 2 days later, I was on the side of the road. I took my car to my brother this time (he's a licensed GM mechanic). There was absolutely no evidence of any wiring being cut out of any wiring harness and they had wired the ignition modual to direct power vs. Directing it to a fuse, thus causing another ignition modual to blow. When I called DG Coates and spoke to the manager, he flat out denied that anything like that would have happened at his shop. He was rude and belligerent towards me and would do absolutely nothing for me. He only said that I could bring it back in, but by that time the issue that they had cause had been fixed by my brother. I deffinatelt didn't have another $700 to throw away in xxxxxx service. I will never be back.
