My new GLA sometimes shoots forward while my foot is not even on the accelerator. It accelerates so fast that my head hits the head rest. I know for a fact that it's not anything that I'm doing, as I've tried to unravel this puzzle, and I've been extremely careful. It only happens in the mornings when I use the vehicle for the first time. Could it be that there is an oversupply of fuel? Has anyone heard of such a problem? This is very dangerous, as I could easily hit a pedestrian or vehicle.
