TOYOTA SIENNA HYBRID 2023 UNKNOWN OR OTHER
low
While driving on the freeway with my small children in the backseat a loud pop sounded and glass from the moon roof came shattering down upon us. The glass hit my face, arms, hair, and fell into my seat and all around the interior of the car. Though glass fell along my face my vision was not obstructed and I was able to safely exit the freeway without accident. The glass, though did make its way towards the backseats, did not hit my children. There was no warning or issues with the car or window.
