Our 2009 GMC Acadia, with front wheel drive, rolls backward when parked on a slight incline even when the transmission is in drive. This past weekend it rolled backward hitting my husband who was walking behind the vehicle. He wasn't injured but we believe this is a serious safety issue especially if children are involved. Also, the vehicle rolls backward, approximately one foot in distance, after the vehicle was placed in park and is parked on an incline. This also happened when the vehicle is stopped at an intersection, in drive, and when on an incline. This could cause an accident.
