So I had my XC90 parked in my garage with the garage door closed and walked behind the car to get to the other side. Next thing I know I see the lights flash and hear the sound of the tailgate opening. I quickly applied pressure on the tailgate to prevent it from opening and hitting the garage door. Once is sensed the pressure, it reversed and closed. Close call! I think my foot activated the sensor when I walked behind it. First time this happened. I always lock the tailgate when I park in the garage but I probably forgot this time.
