Battery Dead problems of the 2011 Honda Pilot

While making a 3 point turn in a driveway in order to parallel park on the street my 2011 Honda Pilot accelerated at a high rate of speed and hit a parked car. My 2011 Honda Pilot continued out of control hit a curb and almost hit a chain link fence which would have caused me to travel into a busy four lane road. My 2011 Honda Pilot stopped by pressing both feet on the brake. Five hours later my battery was dead. I had aaa roadside service replace it. I took my 2011 Honda Pilot to the dealership today where the service rep agreed that there have been acceleration problems with the Honda Pilot. He had me go to a body shop next door where the rep told me he would only work on the body problems. He advised me to go back to Honda because I wanted to know what may have happened and to be sure my car was safe to drive. When I went back to Honda the same rep told me he did not tell me that Honda had any acceleration problems.

Went to start vehicle. Battery dead. Dealer sais to jump start and bring to dealer. Dealer said air conditioner relay stuck and drained battery. July 28, 2013 same problem. Charged battery, car started. 6 days later, same problem. Battery completley dead after 6 days. Took car to dealer. They said there was not any problem. Said we just needed to drive car more. Car has sat in garage for up to 3 weeks before without any problem. Seems ther has to be an undiagnosed electrical problem somewhere in this car.
