Adaptive Equipment problems of the 2012 Hyundai Veloster

I was driving my car down a country road. No cars in front of me and none coming towards me. My husband was following behind me because we had just picked up car from having its first oil change and tire rotation. I was doing between 45 and 50mph. All of a sudden there was a loud bang like a gunshot and I heard something raining down on my car. I looked in the mirror and saw glass flying everywhere. I pulled over and asked my husband if something hit the car. He said no - it looked like the glass in the sunroof blew straight up like a coke exploding. The glass actually hit the front of his car. The glass was in my hair, down the back of my shirt and pants. The glass scratched me in several places.
