A week or two before the incident I noticed that the light on the rear defrost button no longer turned on when the rear defrost button was pressed. I wasn't sure if the rear defrost was working or not. On the morning of the incident it was cool outside and the windows were frosty. I pressed the rear defrost button after starting the truck and it once again did not light up. I started driving to work with my two kids in the back seat. After driving a couple miles I heard a loud noise as if something had hit the truck. I looked in all the mirrors to find what had hit the truck and noticed that the passenger side of the rear window had shattered. It hadn't fallen out of the frame, but was spider-webbed throughout. When I took the truck to the dealer the service manager said he had seen 5 other 2010-2011 F-150's just this winter with the exact same issue. This should be considered a safety issue. From other complaints that I've read the window does sometimes shatter out of the frame and into the cab of the truck. If it had done so in this instance it would have fallen in the face of my 11-month old son sitting directly under it.

Rear defroster would not work. 5 minutes later it came on for just a second and all of a sudden there was a loud bang and the window on the right side of the rear next to the slider shattered. After doing more research, I discovered that is has happened before on the 2011 Ford but there hasn't been any recall. This is dangerous. Thank you

The passenger (ps) section of the rear window shattered without warning & without any external damage to the window. There was a slight frost on the windows & the vehicle was started and the rear window defroster button was depressed and would not activate. As the vehicle was driven at 25 miles per hour an loud pop noise was heard. The vehicle pulled off to the side of the road & it was noticed that the ps section of the rear window was completely shattered. The Ford dealership the vehicle was purchased from was contact to see if there were any bulletins for this issue. The dealership advised that there was no bulletins for this issue however, they have seen this issue multiple times & directed me to call the Ford Motor Company customer service line to file a complaint. The dealership also mentioned that the rear window that needed to be replaced was on back order & that additional repair locations should be contacted to replace the glass if immediate repair was needed. Two additional repair locations were contacted, both of them had the rear glass on back order. A call was placed to the Ford Motor Company customer service line with this compliant, direction was given that Ford Motor Company was not do anything for this issue & that the incident should be reported to the insurance company for repair. The incident was reported to the insurance company & the deductible was paid to have the rear window replaced. The insurance company repair location also was aware & replaced several rear windows for this vehicle due to unexpected shattering with no external impact, some of the repairs were repeat repairs. The location also advised that the probable reason for the shattering was due to the heater element in the glass over heating overtime causing window failure & that it was possible the failure was going to happen again.
