WHILE DRIVING ALONE IN THE RAIN FROM SPOTSYLVANIA, VA TO CLEMSON, SC TO ATTEND MY DAUGHTER'S NURSING WHITE COAT CEREMONY, OUR 2016 S80 SUNROOF EXPLODED AND SHATTERED ON I-85 SOUTH NEAR KANNAPOLIS, NC FOR NO REASON. THE TIME OF INCIDENT WAS AROUND 11:15AM. IT HAD BEEN RAINING AND TRAFFIC WAS STOP AND GO ON I-85 WITH SPEEDS ABOUT 30-35MPH WHEN THE SUNROOF SUDDENLY EXPLODED, SENDING PIECES OF THE SHATTERED GLASS FLYING OFF BEHIND MY CAR WITH SMALLER SHARDS OF GLASS COMING DOWN THROUGH THE INSIDE SUNROOF RETRACTABLE VENT WITH DROPS OF RAIN. I IMMEDIATELY PULLED INTO THE FAR RIGHT LANE TO GET OFF HWY TO ACCESS THE DAMAGE AND FIND SOME COVER AS IT WAS RAINING AND COMING INSIDE SUNROOF. I HAD NO IDEA WHERE I WAS OR WHAT STATE I WAS IN UNTIL I PULLED OFF THE EXIT AND IMMEDIATELY FOUND A SHELL GAS STATION WHICH ALSO HAD AMPLE ROOF COVER. I GOT OUT AND SAW THAT MORE THAN HALF OF OUR SUNROOF WAS MISSING AND THERE WERE TINY PIECES OF GLASS LAYING ON TOP OF THE INSIDE PART OF SUNROOF AND ALONG THE BACK PART OF THE ROOF AND TRUNK. I CALLED OUR AUTO INSURANCE COMPANY, USAA, AND THEY TOOK CAR OF THE REST.
