I have a 2008 G6 GT coupe, with only 1400 miles on it.. After a couple days after the car was bought, at idle the engine randomly hiccups or shakes a little bit every 10 seconds or so. I have owned plenty of brand new cars and I have never encountered this. The engine is usually smooth and hiccup free. Is this a characteristic of the 3.5L or the G6? I really dont want to bother dealing with the damn dealers if this is a normal thing and I'm just being picky. One of those things, take your three day old car in for a leak in the seatbelt pillar and they have it for four days. Not the greatest time, but thats all fixed. haha. Please help!!
