THE FRONT PORTION OF THE PANORAMIC SUNROOF ON MY KIA SORENTO 2013 EXPLODED WHILE I WAS DRIVING THE CAR. I DID NOT SEE ANYTHING COMING TOWARDS THE CAR THAT COULD HAVE HIT THE SUNROOF. THE DAYS WAS APPROX 90 DEGREES AND THE CAR HAD BEEN HOUSED IN AN INTERIOR GARAGE ALL DAY. I HAD BEEN DRIVING FOR ABOUT 15 MINUTES, I DID NOT GO THROUGH AN UNDERPASS BEFORE THE INCIDENT, MY SPEED WAS APPROX 50 MPH. THE SUNROOF WAS PARTIALLY OPEN AT THE TIME. THERE WAS A VERY LOUD SOUND THEN SHARDS OF GLASS EVERYWHERE. I PULLED OVER IMMEDIATELY AND DID NOT SEE ANYTHING ON TOP OF THE CAR THAT WOULD INDICATE IT WAS HIT BY SOMETHING. I HAD MINOR CUTS AND AFTER CLEARING THE GLASS DROVE IT RIGHT BACK TO THE DEALER. IT'S REPAIRED NOW BUT THOUGHT I WOULD POST SINCE THERE IS AN INVESTIGATION INTO A HYUNDAI MODEL WITH A SIMILAR PROBLEM. *TR
