The brake lights would randomly come on and stay on when car was off and sitting still. I replaced the brake pedal position sensor and it seemed to stop. Now, the brake pedal doesn't come back up all of the way after applying the brakes. This keeps the brake light on and the brakes slightly applied. The only way to get it all the way up is to pull it from behind with your foot. This seems to be part of the brake pushrod and brake assist issue they are having, but haven't done a recall.
