When I had problems with my ignition switch I also noticed when I picked up the car from having that fixed that my interior light wasn't working. I told the dealership and they replaced the bulb. The day my warranty ran out the light broke again. I opened it up and the bulb wasn't blown. I had a friend who's a mechanic take a look at it and apparently there is a short in the electrical bracket running to it. If you push up on it sometimes it will pinch the wires enough to make it work. Other times it just doesn't work at all. This isn't a major problem but I find it ridiculous that I 5 year old car has faulty wiring. This could have caused a major problem if it was any other system that was broken. GM really has gotten on my bad side and I don't think they will ever get back on my good one. My husband owns a Saturn that's the same year as mine with WAY more millage and the ONLY problem he has had with his car was he blew a computer system when changing the battery but that was user error not equipment error. This is down right sad.
