Wife was driving home on a 30 degree snowy day with rear defroster on. Backed into the garage and as she turned the truck off a lot bang occurred. I was in the garage at the time and realized the passenger rear window spider cracked and essentially shattered. Ford says there is no recall, had replaced the next day for 600 dollars.

While driving on a local road (approx. 45 mph, raining, approx. 50 degrees outside) heard a sound that sounded like a gun shot. Looked around and didn't see anything next to me or behind me. When next stopped the truck got out to check to see if something happened to the truck body. Then realized the passenger side back rear window shattered. (it's a 3-part rear window.) looking very closely, the glass spidered, starting from the bottom corner closest to the center window up to the opposite top corner. The glass spidered inside the car. Outside the glass, although still intact, was buckled facing out. At the time this happened, the rear window defroster was on. When got back in truck to travel home, during the drive the window broke with small pieces of glass falling all over the back seat. Very lucky that no one, family or pet, was in the backseat when this happened as would have been hit by broken glass. Believe this issue is related to rear defroster along with glass manufacturing. Contacted the local Ford dealership and since car is out of warranty they can fix but at least $1000. Contacted Ford Motor Company, no recall available.

2010 Ford F150 platinum left rear window shattered when using rear window defroster. Turned defroster on and heard a loud crack after approx 3 minutes use. 11/21/2015. Similar to other scenarios and replies posted here but I have added some photos. It would appear a water leak has caused water to build up in the track and shorted the circuit. 1st image of shattered window. 2nd image of melted window casing.

Blend door actuator, temperature actuator, heating & air system quit working correctly on driver's side of vehicle. Apparently this is an issue on other Ford models. Luckily I was not in a situation where the windshield was foggy or icy. But very concerned that it could be a problem for others. If this part would fail someone in a ice storm or very humid conditions, it would become a vision problem for the driver. In researching this issue several others people have had problems - I do not know if any resulting accidents occurred.

Started rear defrost due to fog on the windshield. Drove about 5 miles at 25 mph and heard a very loud pop. It sounded like something hit the roof. Proceeded to work and looked at the rear glass. The passenger side rear window was completely spiderweb. Tape was placed on the window in an effort to hold shards of glass that were falling off. As I was taping additional small glass shards were found. Ford is unwilling to admit that any of this might be due to a product defect. This will cost around $600 to replace and of course a day off work.
