I've had my Stelvio for a month and this just started happening: When I come to a stop at an intersection in D (Engine Stop/Off). The parking sensor activates even though there is no car in front of me or behind me. The car graphic appears on the screen with a red warning area in front, audible beep and the words "please check entire surroundings," or words to that effect. Had to turn off Park Sense. Anyone have an idea what the problem is? Thanks.
