While driving into work at 0445 hrs on a smooth road with an outside air temp around 5 degree I heard a loud bang coming from the cab area of the truck. I had let the truck warm up before driving and turned the rear window defrost on approx. 2 miles before I heard the noise. In checking my vehicle, I noticed that passenger side rear window had busted. When I spoke with the Ford dealership, they said they were aware of the problem but did not feel it was bad enough to have a recall. It sounds like it is going to cost approx. $800 if it is not covered by my warranty.

I started my truck Jan. 27th,2014 on a very cold morning and turned on the rear defrost on my 2010 Ford F150 super crew-cab truck. I let the truck warm up and when I got to my destination I noticed the rear, passenger side window was shattered. I have seen many complaints on the internet with same the problem which sounds like it could be an electrical problem. I got an estimate to get it fixed. They wanted over $800. I have a $500 deductible on my insurance. I don't need this expense. I will be calling Ford customer service number to complain.

I started my truck up and activated the rear defroster. It was extremely cold about 11 degrees in NJ approx. 5 minutes later I detected what appeared to be a crackling noises which resulted in the rear passenger window popping and shattering. I have recently contacted Ford and advised them. I was told my vehicle is out of warranty and they cant help me out with this issue. There is obviously a defect in the glass for that year due to there being thousands of issues related to the same issues on these vehicle. As a long time Ford customer I feel this is enough of an issue which will cause my to switch my choice in future trucks.

Started the car in the morning. Turned on the rear defroster. Began to shovel the driveway and heard a loud pop from the truck. Didn't notice anything until I got in to back up and saw the rear passenger window gad shattered. Ford dealer was very familiar with the "window" problem, as they described it. Said that because the vehicle was past 50,000 miles that it was no longer under warranty. I rarely use the rear defroster. The dealer said I should take it to the local glass specialist to have it replaced. They never mentioned that it may be an electrical problem. It seems to me that a known repetitive problem should be paid for by Ford. If it is an electrical problem, I may be replacing my window more than once.

The right rear window (passenger side) shattered for the second time, when the rear window defroster was being used.

- Elkhart, IN, USA

The right side of the 3 piece rear window with defroster shattered after I turned it on. I had driven maybe 1 1/2 blocks after turning it on. I don't feel safe turning it on anymore. The window replacement company did not know what caused it. I bought the vehicle used with about 24050 miles on it so I don't know if this has happened before.

I had turned on my rear window defroster and after about 5 minutes I heard a loud bang. The right side of the rear power sliding window had shattered.

- Fortson, GA, USA

Was driving into driveway at approx. 5 mph and heard load pop. When got into garage I got out and noticed passenger side back window was shattered. When I was driving home I had turned on the rear window defrosters about 4 minutes before this happened. Looking into this, it seems to be a common problem with Ford and they don't want to acknowledge any problems.

In the morning I turned on my rear defrost it was aprox 40 degrees out. About 10 minutes into my drive I heard that sounded like a gun shot inside the truck slammed on the brakes and pulled to the side of the road... looked around didn't see anything. As the sound seemed to come from the roof of the truck I looked at the roof and didn't see anything. I discounted it as a car backfire and proceeded to the gas station. At that point I noticed my rear passenger side window had exploded. Later examination I discovered many complaints of this problem. I have called Ford both dealer and corporate and they said they have no record or recall of the problem. This does pose a safety hazard as the sound of the window exploding is very loud and distracting and typically as I've read happens in motion.

- Eastlake, OH, USA

I was sitting in my car with the rear window defroster on (60 or 70 degrees outside) and heard a very loud pop. When I looked at the back window it had exploded (shattered completely with no spider web cracks) and no one driving nearby, cutting grass, walking, etc - there was no one around, nothing next to the truck or in the bed that could have hit the window. I looked it up online in multiple forums and found that a very large number of complaints described the exact same thing happening to 2010 F-150S with rear defroster on. The window replacement company in town also stated they had replaced 3 or 4 windows that had the same thing happen. I'm lucky no one was sitting next to the window because small shards of glass fell into the seat and interior of the truck.

This morning I switched on my rear defroster. Outside temperature was around 50 degrees. With a few minutes I heard a loud pop. Inspecting the glass of the vehicle I found the driver's side rear window broken (spider webbed). The dealer is telling me that glass is not covered under the extended warranty.

While driving I put my rear defroster on and I heard a very loud popping sound. When I looked in my rear view mirror I noticed the back window shattered.

- Fords, NJ, USA

I was driving and heard a very loud bang. Then I heard the rear window crackling and looked back and noticed the rear passenger side window had exploded and shattered. It was only being held together by the factory tint but there were glass shards throughout the back seat where my children sit. The window is a power sliding rear window with defrost. I also had the rear defrost on during the time which may have contributed to the window shattering.
