This morning when I was backing out of the garage I put the car in reverse, released the brake, and the car put itself back into park. The first time I thought I had forgotten to shift, but this happened 4 or 5 times: the panel would show I was in reverse, the backup camera would show on the screen, then release the brake and *poof* - back into park. Parking brake was not engaged if that makes any difference.
Turning off the ignition, giving the shifter the finger (obviously the important step), and restarting made it work. Anyone else ever encounter this? I'm just chalking it up to a glitch in the matrix for now.
