2013 Hyundai Santa FE wipers, windshield & visibility problems

While traveling on the highway at 75MPH there was a loud bang (like an m80 exploding). I was very dazed and was unsure what had happened. The sunscreen was closed and seemed to be flapping as if wind was blowing on it. I was able to pull over to the side of the highway. When I got out of the vehicle I found that the sunroof had exploded and that the edges of the roof were pointing straight up. The sunroof was closed at the time of the explosion and the temperature was about 70 degrees.

Tl* the contact owns a 2013 hyundai santa fe. While driving at approximately 70 MPH, the sun roof shattered. The vehicle was towed to the dealer, but was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 4,500.
