After about a week long trip, I returned to the airport long term covered parking and found a 10" crack in my XC90 windshield. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/mad.gif" BORDER="0"> <p>No sign of impact, just a crack. The cause remains mysterious since it was not there when I left the car.<p>I called my insurance agent and the dealer and had a new windshield installed 2 days later. While at the dealer, I got the T6 tranny and radio software upgrades. Have not had a chance to really check them out yet.
