I had something really weird happen today. While driving down a snow covered road to my parents home, I began to slow down to make a left hand turn into the driveway. The abs kicked in and the vehicle continued to slide as the wheels appeared to lock up. So, I left off the brake and let the tires roll naturally through the left hand turn up a slight incline into the driveway. While approaching the top of the driveway I applied the brakes and stopped. I then looked over at my wife and removed my foot from the brake to pull up further and the vehicle immediately rolled back out of the driveway while in still in drive. So now that I am out of the driveway in the middle of the road, I re-apply brakes. Look down at the gear selector and then put it in park. I then press the throttle and no engine response. I glanced back at my wife and said what turned the engine off, the key was still in the on position and there was not a single indicator on the dash that appeared out of the normal. I turned the key to off and restarted and it was fine. If GM is listening and it's designed to do this, this is a major recall waiting to happen. After thinking about it an hour or two later, I probably should have called on-star at the moment that it happened. Am I crazy, or has this happened to anyone else?
