Defroster/defogger/hvac System Rear Window problems of the 2005 Ford Escape

My 2005 Ford Escape was sitting in my carport for 2 days. I went out to go to the store and the back window was shattered in a million pieces all over the driveway and back bumper. That was also glass inside the car. I called the police and they came out and looked at it and took pictures and I took pictures also they said it had not been vandalized that it must have exploded from the inside out. I read about a lot of other people having the same problem. Ford needs to have a recall on this. It could have happened while I was driving or children could have been hurt sitting in the backseat this is not like.
