2003 Acura TL electrical system problems

My daughter died in a accident on november 7, 2013 in the acura tl 2003. She had been telling me that it felt like the ignition was sticking and would speed up. I would check with my local mechanic and he told me acuras are known to idle high. I believe that her car problem was the cause of the accident and the police could not give me a reason for the accident. She was 19 and a senior in high school and was a good child.

Tl*the contact owns a 2003 acura tl. After parking the vehicle and walking approximately two feet, the vehicle began rolling backwards on its own. The vehicle was stopped when it crashed into the passenger door of another vehicle. There were no passengers in either vehicle at the time of the crash. The other vehicle was damaged and the contact's vehicle sustained scratches to the rear bumper. The vehicle was driven to the dealer and they stated that the ignition interlock was defective and needed to be replaced.
