NHTSA Complaint #11308276 — 2016 BMW X5

I WAS DRIVING MY BMW X5 AT APPROXIMATELY 9:30PM ON INTERSTATE 93 GOING NORTH IN MASSACHUSETTS, WHEN I HEARD A EXPLOSION ABOVE MY HEAD. I IMMEDIATELY EXITED THE HIGHWAY TO EXAMINE WHAT HAD CAUSE THE EXPLOSION. WHEN I EXAMINED THE ROOF OF THE VEHICLE, I NOTICED A HUGE CRATER IN THE CENTER OF THE SUNROOF WITH SHARDS OF GLASS COVERING MOST OF THE CRATER WHERE THE INTACT SUNROOF WAS LOCATED. I DID NOT NOTICE AND OBJECT THAT MIGHT HAVE CAUSE THE EXPLOSION, NO ICE- IT IS WINTER IN MASSACHUSETTS, NO ROCKS THAT MIGHT HAVE IMPACTED THE SUNROOF TO CAUSE THE EXPLOSION, THE ONLY THING THAT WAS VISIBLE TO ME WERE BROKEN GLASS. PRIOR TO THIS EVENT, I HAD NO REASON TO BE CONCERNED THAT THERE WAS SOMETHING WRONG WITH THE SUNROOF, I HAD NEVER HEARD ANY SOUNDS COMING FROM THE SUNROOF AND I NEVER HEARD OR SAW A ROCK, PIECE IF METAL OR ANY OTHER OBJECT IMPACTING THE ROOF OR SUNROOF.
