So I live in Calgary, Alberta. Was leaving work last night and the temp was -19*c which is about 2*F. I opened the back door of my GS to put my bag in and closed the door and it flew back out. Spent 20 mins trying to get it to stay shut, before deciding to drive home holding it closed. Got home and thought great I'm gonna have to go to the dealer to get them to fix it in the morn, since I thought something had broken inside. Decided to try a blow dryer on the latch just in case, and yup it worked. Crazy cold, you take a chance just to open your doors in this weather...

Has this happened to anyone else?
