Carrier/rack problems of the 2005 Infiniti FX35

I opened the sunroof while driving about 60-70 mph on the highway and the glass of the sunroof completely flew off the car and went up in the air about 30-40 feet. The break or separation of the glass from the roof was clean so there was no damage to the sunroof mount/bracket which still operates like it should without the glass. This is vary dangerous as it could kill someone driving behind me. My insurance company said that the sunroof glass should not break apart from the mount of any vehicle, that I should contact the manufacture. I called Infiniti consumer affairs and they do not want to do anything for me.
