While driving on a northern California highway on 12/23/2016, I heard a huge explosion and saw that my sunroof had exploded. I immediately closed the hatch to prevent glass from coming into the vehicle. When I pulled over and got out to look at the damage, I noticed that the glass was pushed up - indicating that it had exploded outward not inward (as in something falling on it).

I was driving on hwy 32 when I heard a loud explosion and glass shattering. I pulled over to inspect my vehicle. I noted no physical damage to the outside of my vehicle. I got back in my vehicle to inspect the windows. I pulled back the visor to my sunroof and there was glass everywhere with a big hole in the middle. I exited the vehicle to see if an object had hit my sunroof and found no objects, other than pieces of glass.
