Was driving with 2 family members in truck.had back window down which was a good thing,when sunroof exploded it inbedded glass in the topper that was on the truck.glass was all over us ,luckily we were not cut and i dont know how we wasn't i stopped immediately and got away from the truck because i thought we had been shot at with a shotgun.i called toyota to report it and they said they had no other calls like this.my insurance company paid the whole bill which was a lot.i do not open the sunroof at all now because i have a fear of it happening again. i keep the cover slid over it.
