I have a GMC truck. I took it to your dealership for "ABS Light" and "Service Traction Control" and "Service Stabilitrak". After they supposedly fixed it, I have taken it back 4 or 5 time as these lights come back. They are not able to fix it. Now, they are saying the problem is with the brake drum that needs to be replaced spending another $500 plus. I feel that the crew has worked on it are incompetent. I need my money refunded, so, I can take it somewhere else.
