When driving on the freeway, the left rear "vent" window had its glass come completely out of the channel which holds it, and was dangling by just a bolt. upon inspecting the window, i found that the window's adhesive had completely failed. i reported the problem to the toyota dealer, and even though the vehicle was still in warranty, they refused to repair it without charging me the full repair price. the risk of a glass window falling off of a vehicle at high speed seemed very high to me, but the dealer said there were no recalls or safety problems. *tr
