We were driving our 2003 Toyota Sienna xle limited down the street at approximately 25 mph when the moonroof shattered. The shattered was spontaneous and made a loud popping noise when it occurred. There was no impact from a rock, debris or object at or prior to impact. The moonroof/sunroof shattered into pieces. After research on-line, I see there was multiple complaints from owners of Toyota tacoma, scion and Sienna.
