Exploding sunroof. Same thing happened to my daughter. Driving down the highway and her sunroof exploded. Right now car is in Lexus shop and they are refusing to pay for. Saying extended warranty doesn't cover "glass" However, I see Lexus corporate has paid others. Any suggestions ?? This car also has leaking rain water which they did cover under warranty. Wondering if one thing has to do with the other? UPDATE ! My dealer has agreed to cover ! Love my Lexus. I have two of them . Will never buy anything but LEXUS !!
