got home and just started snowing, both slots in the garage are taken so I decided to park the X1 on the driveway with the parking brake pulled!! Around 10 seconds gone by, I heard this "not loud" alarm going off so I ignore it cause I thought it was somebody else's car and our neighbor alerted us that your car is in the middle of the street. She thought I was in it and wondering why would I just stop there. She also mentioned the alarm that she heard but not loud. The picture above is the second time of it doing it again. Yes, I did and tried it again after parking and making sure the parking brake is on again. I saw it slowly sliding again and picking up speed!!
