general problems of the 2013 Infiniti QX56

I was driving across a bridge in town going about 40mph. Nothing was over head, driving conditions were good, weather clear and all of sudden out of no where I heard an explosion. Extremely loud, made my ears ring. I immediately thought something blew up or my car had been shot. I started hearing pieces of glass hit my sunroof cover and pulled up to find my glass had exploded and left a huge hole in my sunroof. The glass exploded from the inside out. I immediately took my vehicle to the Infiniti dealership where I purchased the car brand new. They agreed that it had exploded from the inside out and said they had seen this before. I was asked to pay $1261 to replace the glass since my car was not under warranty.
