2012 Kia Sorento wipers, windshield & visibility problems

I was traveling home at approximately 55 MPH at the time of the incident. The sunroof was fully closed and had imploded with no known cause. Glass had fallen on both the driver and passenger resulting in minor lacerations. No other vehicles were visible on the road at the time of the incident and no foreign objects such as rocks were found in the vehicle. ... Updated 03/19/15 updated 6/19/2015

On friday, oct 17, 2014 I drove over 600 miles with my son to an event and returned home. The next morning I discovered the sunroof was shattered. The car was parked next to our house in our driveway at the time. It was very strange as nothing had fallen on the car and there appeared to be no cause. When I called the kia dealership they initially denied knowing of any similar problems with sunroofs shattering.
