My drivers seat has some serious indecicive attitude. Lately it's been moving back on it's own. When I go to get in it, the seat's all the way back, but not all the time, so it doesn't have anything to do with the easy exit option and it doesnt move until well after I've exited. It didn't do this until lately, after my 2 year old niece got in there and started pushing buttons. Any ideas on what the little genius did to my precious Acadia to make it do it's own thing ?????
