Was entering highway and reached speeds of about 70mph when all of a sudden the sunroof exploded and shattered. I immediately contacted Lexus as I knew nothing could possibly hit my car at those speeds and not come flying through the roof and damage the frame and other moving parts. The only thing that saved me was that I had the interior slide hatch halfway closed so glass didn't enter the vehicle. I immediately shut it and drove to the dealership. The agent who looked at my car reported that this type of incident has happened in the past and it looked remotely similar. We checked for a rock like structure by shining a light in the roof area and nothing was found. I contacted Lexus executive office and while they were extremely helpful, the theory that something hit my car was not supported by the law of physics or motion. If something hit the top of the vehicle while I was driving down the highway at 70mph the speed of impact from the object would be doubled even tripled and definitely inside my car or on top of my head. The trajectory path from this object had to be spot on and come from extreme heights and distance to land on top of the car. There would have been much more vehicular damage and I could have been seriously hurt if that were the case as the hole is more on the passenger side. All in all no one was hurt and thankfully my sunroof will be replaced. I feel as this has happened on more than several occasions as to why I was taken care of so quickly. I just learned that there is a class action lawsuit in another state about the rx sunroof exploding.
