Sudden acceleration when braking caused crash of 2011 Toyota RAV4 and driver injury. Making a right turn into a parking space that faces a concrete wall, I had my foot on the brake to slow the car down to park, going about five miles an hour. Still riding the brake, never having moved my foot off it, when I was about two feet from the wall I pressed on the brake to ease into a stop. Instead, the car suddenly accelerated with a loud rev and crashed into the wall. The car was going so fast the airbag deployed and thrust me against my seatbelt. Airbag caused fracture of 5th metacarpal in my right hand. Was unable to drive for 12 weeks. When I got the car back from the Toyota Body Shop ($9000+ in repairs), I took it over to the dealer and began filing a case with the Toyota Customer Experience Center to have Toyota inspect the car. I am especially concerned about the brake sensor system. Case is pending
