2016 BMW M235I Unknown Or Other Problems

IN LATE FEBRUARY 1, 2019, THE SUNROOF ON MY 2016 BMW M235I XDRIVE EXPLODED WHILE DRIVING ON THE GARDEN STATE PARKWAY. I WAS NOT GOING UNDERNEATH ANY OVERPASS, AND NOTHING HIT THE GLASS. THE EXPLOSION WAS UNPROVOKED. THE SUNSHADE WAS NOT CLOSED, AND THE GLASS FELL ALL OVER ME, LARGE AND SMALL SHARDS. I WAS DRIVING ABOUT 65MPH IN HEAVY MORNING RUSH HOUR TRAFFIC, AND PIECES OF GLASS FLEW OFF THE CAR AND LIKELY HIT OTHER CARS. IT WAS VERY ALARMING AND SCARY. I WAS ABOUT 5 MILES FROM A BMW DEALER AND DROVE RIGHT TO THE DEALER WHERE THE CAR IS STILL SITTING WAITING TO BE FIXED. BMW IS REPLACING THE GLASS AND SUNROOF ASSEMBLY UNDER WARRANTY. THIS WAS A VERY DANGEROUS SITUATION AND WITH THE GLASS FALLING ALL OVER ME COULD HAVE RESULTED IN INJURY TO ME, OR SOMEONE ELSE IF THERE WERE OTHERS IN THE CAR, OR...
