Every 3 to 6 months either left or right low beam headlights (silverstar H11) are going out. The affected socket is extremely hot. Either there is a problem with the quality of the headlights or their is an electrical issue with the socket that keeps burning these bulbs out prematurely.

My car, on four separate occasions, while I'm either driving on the freeway, or long stretches of roads, has malfunctioned, starting with the service stabilitrak indicator coming on, then traction control off function flashing, then the engine reducing speed until you're able to pull over and eventually stop before the car cuts off. I have taken it to the dealer twice in an effort for them to tell me what's wrong, and each time, they either didn't know, or were unsure. The last time I took it, after being instructed to make sure the check engine light was on, they still were unable to tell me precisely what was wrong, and that they changed a relay, and if that wasn't the problem, the whole fuse box needed to be replaced. I have called GM in response to this, asking how on earth would a fuse box need to be replaced on a vehicle that's only three years old with less than 100,000 miles, but of course their customer service department wasn't helpful in that regard. When I finally spoke to the dealership again, they let me know that the part was on national backorder. That indicates to me that their is a national problem with either the car or the part. I called GM again but was told that it is normal for a part to be on a national backorder. I'm not buying it, and I believe there are many owners with the same problem, and they won't want to own their problem, and leave the vehicle owners on the line to pay for repairs for something that's clearly defective. Please hold them accountable!
