I took my newly purchased, used v50 wagon to my volvo dealer. the service tech demonstrated that the windshield has become unsealed from frame. it was/is loose, and can be partially pushed out. they had found wet carpet in my car. it is still leaking (the car had not been in an accident). this was not covered by volvo, nor was it covered by the extended warranty i had purchased when i got the loan. turns out this is a known issue that volvo should fix at no cost to me.
