On two occasions so far in 2018, my Buick engine would start itself. Once when I closed the glove box and another time when I closed the passenger door. Both times the ignition key was absent and the car was stationary. My guess is ignition switch. Thor nielsen - mechanical engineer & college auto instructor.
