The rear-window defroster over heated on the passenger side causing that window to chatter. At one spot at the bottom, the rubber frame around the glass started to melt and burn just before the window chattered. If I had not been standing close to see what was happening, and turn the control off, I believe this could have started a fire that could have burned the entire truck and areas around it threating people and property. This is also a safety concern for anyone sitting in the back seat at the time of window chattering, as small shards of glass could hit passengers possibly causing eye and other injuries. Due to my incident, I did research on YouTube an other Ford forums that document many others being a victim of this same problem over several years including 2010, 2011, 2012, 2013, 2014, 2015, 2016 and maybe more. Owners over the years have documented and informed Ford about this problem, apparently without any trucks being recalled or getting much help from Ford about this problem. Ford and NHTSA should be concerned and Ford held accountable for this defect. Many owners were told buy the service men that replaced their back glass because of this issue, that this was quote a "common problem caused by the defroster" on this trucks. If there are "safety concern" that yell "RECALL!", this is for sure one of them.

I hit the remote start on my truck this morning and when I walked out to my truck and got in to head to work I heard a loud pop and didn't know what it was at first. I looked back and my back right rear window was shattered. I don't know how or what happened. I just heard the noise and looked around and noticed my window exploded. I got out to look at it and when I shut my door the window fell apart.

- Greenfield , WI, USA

Driver side-rear defrost window shattered for no reason. The truck has a cap on the bed. Now have to get the cap removed to have it repaired. Ford said no way to cover even the $100 deductible. Terrible service when I spent $30K and they can't chip in when there is a defect. And the entire rear window will need to be replace, not just the section.

The rear window on my F150 broke while my wife was warming up the car. The only thing she did was turn on the rear window defrost.

- Phila, PA, USA

Driving down the road at about 20mph. 7 and 9 yr children in back seat. Turned rear defroster on and about 2 min later heard very loud noise like something hitting my roof. Didn't know what happened till I looked in my mirror and saw driver side rear stationary glass pane spider webbed. Looked at roof and see nowhere where something hit roof. From what I am reading this is a common problem that has not been addressed by Ford.
