I was driving my 2000 Volvo S80 on 5/19/10 and had exited I-405, onto hwy 169, heading home towards maple valley, when all of a sudden I heard a very loud bang, resulting in sudden steering loss, heard loud squealing, and saw lots of white smoke. The smoke was from the front passenger tire, which had turned outward, completely sideways at a 90 degree angle. The car is now in no condition to be driven. The wheel damaged the frame, warp/dented the quarter panel, broke off the molding, ripped out the cv drive or whatever that thing is that makes the wheel turn in a normal, forward direction, broke the lower control arm, messed up the brake line, struts, and who knows what else? I'm guessing that the repair costs are going to be towards the thousands, being that Volvo parts are so expensive.
