Sun Roof problems of the 2006 Infiniti M35

I got in the car this morning and my sunroof was fine. I pulled out of my parking spot and that was when I heard this cracking sound. I got to my destination which was less than 1/2 mile away, I parked the car got out and took my daughter into school. There was nothing on above my car, I parked in an open area. When I got back in the car and closed the door it sounded as if glass popped from somewhere. I got out looked at the roof and my sunroof has a crack along the front and there is a hole that looks like someone took their fist from inside the car and punched it towards the sky. I drove back home trying to see if I could find any indication of how this could have happened because I was just in the car less than an hour ago and my car was fine. I went online to search exploding sunroofs and that's when I found thousands of complaints for Nissan and Infiniti as well as other makes and modes. My husband immediately called manhattan Infiniti and explained the situation and was told that they had never received any type of bulletin about it and they would know if this was an issue. They went on to say that my car was out of warranty so this wouldn't be covered. My issue is that this isn't a warranty complaint there is clearly something defective with the sunroof and I'm not the only one having this issue. I feel that dealer should cover this. I shouldn't have to go to someone else when this is clearly a manufacturing default. This could have caused a major accident if I had the sunroof open or even cracked as the glass would have fell in the car while I was driving and hit me or my children.
