With the rear defrost on the back glass exploded while driving.

- Davenport, IA, USA

On a 20 degree morning I turned on the rear defrost and in about five minutes time I hear a loud noise. Upon looking around I found the back window had shattered on the passenger side. I was stationary at the time, thankfully, because the sound was a lot like a gun blast and if driving I could have swerved, it startled me so much. The window is shattered into thousands of pieces and visibility out of that window is severely hampered. This is an obvious design flaw and it effects the safety of the vehicle and a recall should be issued.

The rear window driver side spider webbed. It was 55 degrees out and I opened my windows. This is the 2nd time this has happened to me. The other time was the passenger side rear window in 11/2013. I believe Ford needs to take responsibility for this.it has to be associated with the defroster.

Driving home with my family from in-laws house. Upon starting the truck I turned on the rear defroster, about 5 min later I heard a loud bang, like something landed on the roof. Later on realized it was the passenger side section of my rear window. It shattered, but remained fully in tact with no impact spot from inside or out. After googling this I see it is a common occurrence among these vehicles.
