My truck was running in park. I got out to open garage door
and while I was opening the door, maybe we minutes, it
jumped out of park and into drive and came at me. What
would cause it to do that?
Trans lever not fully engaged in park?
Definitely wasn't fully engaged in park. If you are absolutely certain it was, and can reproduce the error, your shifter might need to be adjusted... but 99.9% of the time, it was just user error.
Haven't you seen the movie "Maximum Overdrive?" Or "Killdozer?" "Christine?" I bet your car has.
