When driving on highway I-87 our moonroof in our minivan started to blow off. Luckily my husband was in the passenger seat and could hold the glass while I pull off. We immediately called Toyota of clifton park to tell them and took it there the following morning. They gave us two options, one full replacement at a cost of approx 1,340 + tax or to have them attempt to replace the glue and we would have to let it "cure" for a few days. We didn't drive it for approx 8 days and two days after driving it, it flew off again, this time I was alone an couldn't grab it and it blew out and hit another vehicle causing property damage to that car. We told Toyota originally that it had to be a manufacturing defect, you don't drive around and expect the windows to blow out of your car. They said because we were over our 50000 miles they wouldn't be responsible. Now in addition to them not taking responsibility for a defective moonroof, they also gave us bad advise on fixing it. They told us only one very expensive option and then one very cheap. Nothing in between was offered and after talking to our insurance adjuster, there was many other ways to fix the vehicle (only replace the glass, get one from a junk yard etc) but they didn't offer those less expensive repairs so of course we tried the glue. After metlife sent an engineer from an independent company did we find out they used an appoxy that isn't meant for fixing sunroof's or cars.
Sunroof ripped off drivers side of car after it was opened on highway. Sunroof remained attached on passenger side causing broken glass to shower into car and providing unsafe driving conditions at 75mph. Toyota refuses to acknowledge it is a factory defect even when one of their dealers has evidence that sunroof glass was never properly adhered to sunroof mounting brackets.
