So my wife and I were driving down the highway the other day when all of a suden we hear this load BANG! Scared the shit out of both of us. So we pull over, and I get out and look and the sunroof is shattered, with a small hole in it and the glass pointing up toward the sky around the hole. I still can't figure out what happened. We were on an open highway, not going under any bridges, I can't imagine how anything could have come from the sky and fell on the car like that. My only guess is that the sunroof had a stress fracture and just popped!? I really don't know. Anyway, we were on a trip so we didn't know where to go to get the car fixed. So we called up the Lexus 1-800 number, and to our relief we were 15 minutes from a dealer. We drove to the dealer, and within 20 minutes were in our loaner IS300 and on with our trip! Amazing customer service!
