Brought my car in here after another GM dealer proved incompetent to fix my car, turns out this place can't fix a simple issue either. The blind zone indicator on my drivers side was not working, on my BRAND NEW encore. They followed a bulletin published by GM on the issue. Picked my car up tonight, and now NEITHER SIDE'S indicator is working. This was the 4th time I've taken my BRAND NEW car to a GM dealer - all to try and get the drivers side indicator working. And now instead I have both broken.
