I have noticed a much more aggressive applying of the parking brake automatically while I'm backing into my garage. I don't have my seatbelt on, but I'm also firmly planted in the seat. It used to be it would only happen if I twisted or lifted off the seat a bit. Now it happens when I'm sitting square and looking at my backup camera. I'm curious if this was a software change or if my seat's butt sensor is on the fritz? I'm looking for answers other than "wear your seatbelt". I have a large property and a complicated backup procedure to get into my garage. More importantly, I watched a poor valet struggle with this just a few days ago. Poor guy; the first time it happens you think you hit something. How would he know to put his seatbelt on?
