Reported at 16,000 miles, November 2008 Crash

While driving on a long trip, without warning, the memory seats change seat setting and went back fully as if I shut the vehicle off, this happened several times while I was driving without my assistance. I finally realized that when I touched the keys in the ignition, the seat went back to its original setting. When this occurred I was unable to reach brake and accelerator pedals which could have caused a fatal accident to occur.
