We were driving along and I noticed the rear window was fogging / icing up a bit. I turned on the rear window defroster, and not more than 2 minutes later we heard a extremely loud pop sound (like a gunshot). I was stunned, and my wife thought we were being shot at. I barely avoided an accident right when it happened, but was able to slow down and pull over. We could see that the entire back windshield was shattered, and once I got out of the car, the window fell in, glass everywhere. Cut my hand on the glass in the back. Called local Honda dealer, and they said to call corporate, and there was nothing they could do. Wasn't able to get through to corporate Honda USA, need to try again to see if there are any recalls, or recourse for this.
