At first my headlight bulbs just kept blowing and I had to keep replacing them. Eventually, one side went out and would only come back on after the bulb shield was adjusted. The bulb shields eventually stopped holding the device together and my headlights completely quit working all together. I also noticed a melted liquid running down from the bulbs themselves inside the shields. It was apparent that the wiring had melted. I took it to Chevrolet dealer in my city and was told that the entire wiring system melted and had to be replaced including the wire that hooks the system to the battery inside the engine. Turn signals are not even working at this point. I was told that I had to replace both head lamps instead of just the one affected one because if I didnt it would just burn out again. I was estimated $700 for the repair which was way too much for my pockets. I have already submitted this same vehicle for the power steering issues which I paid for and then was reimbursed 9 months later after the recall finally went through and the fuel pump issues that had a recall as well. I recently had to replace a fuel injector as well. I know that the 2005 model had a recall on head lights and I am sure that my vehicle has been affected by the same defective parts. I have been without headlights for 4 months now.
When making right turns, the turn signal indicator will cancel sometimes and not cancel sometimes. It does not seem to matter how far the steering wheel is turned. It has done this since it was new. The left turn signal seems to be fine. As this is a "company car", I have been instructed not to take it in to get it fixed until there is an official recall.
