I had my drivers side go out about 10 days after I bought it (private sale). It did require a trip to the dealer and replacement. I did it that way because I was told by the lady I bought it from that the vehicle had the GMPP warranty, which I had the documentation from. Unfortunately they didn't cover at the time because it requires a transfer fee from the new owner. Fortunately it was within the 30 day window, so I didn't lose it, but I did have to pay out of pocket for the repair which I later was reimbursed for. Fair warning than it's an EXPENSIVE dealer repair. Mine was just shy of $350! I could have done it myself to the price of the part, but I'm glad I did it my route since we discovered the owner transfer requirement. If I recall, the part was around $150, but I have since seen it on gmpartsdirect for about $80. If you have some mechanical experience or know someone who does, I would definitely suggest taking a few hours and saving yourself some $$$.
