I bought my 2006 XC70 2 weeks ago (137,000 kms=85,000 miles) and it came with a broken Park Assist sensor. So today while backing into my parking stall in my condo parking garage the CD player turns itself off and I hear a beeping sound. Also when putting the tranny in R the stereo message screen says "Parking Assist Active".

How can a broken system (sensor) fix itself?
