I've only had my G6 GT (2007) for a few days and am loving it. However, I have noticed a slight "pop" (or thump) when accelerating from a stop or turning at low speeds (usually accelerating then too). It is hard to tell where it is coming from, but feels like from right behind the steering column. I was wondering if it could be a suspension issue (car has 29k miles on it). My wife's Buick Rendezvous was doing something similar at 35k miles and had to have both front outer tie-ends replaced. Is it normal for the G6 to have a little pop (and it is VERY minor, btw) or something I should have the dealership look at?
