My car with only 6K miles start has cracked and frayed seal (the black rubber strip) right below rear hatch window. Dealer will replace and is ordering a new rear window in case they break the old window, because it must be carefully removed to put in the new seal. Anyone else had this problem develop? I'm upset because I had an aftermarket tint on the inside of the window and now I have to do it again, should they break the original.
