Visibility Related Problems of the 2015 Volkswagen Golf

Wiper problem

The panoramic sunroof on my 2015 vw Golf se spontaneously exploded while driving approximately 60 mph on the freeway at approximately 9:15 pm on 2/27/2017 on highway 880 in oakland, about 1/2 mile south of the oracle coliseum. No cars were near me and I was not under a bridge, thus no evidence that the sunroof was struck by an external object. There was also no visible evidence of damage to the glass prior to entering the vehicle, I check every time I buy gas. The glass shattered suddenly in a loud explosion that sounded like a gunshot and shards were scattered throughout the interior of the vehicle and covered myself and my passenger - although most of the shards blew outward and landed on the road. The experience was extremely frightening and could have caused serious injuries. Luckily I was able to maintain calm and slowly drive off the freeway rather than jerking the wheel when the explosion happened. The only injuries are emotional and 12 hours later I am still finding small shards of glass on my person (hair, inside my mouth and nose, on my clothes).
