Bought car second hand, still under warranty.It refuses to start (won't turn over) about twice per month (passlock issue). Very very annoying. Have to wait 15 minutes, flick door locks, and car will start. Head gaskets failed at 40,000 miles. Rocker arm stud pulled out of head a year ago, just happened again last week. GM used weak aluminum heads. The steering clunks, another GM defect. Body control module has been replaced twice. Lots of other problems as well. Last GM car for me.
Well, the sound system hasn't broken, yet.
GM, just take my car and study it. See the reason you needed a serious financial bailout last year.
