Turned rear window defroster on, 5 minutes later heard a loud pop looked in rear view mirror and the passenger side rear window was shattered. When I first turned the defroster on I noticed that it didn't appear to be working. No visible lines across the center window. I turned it off and back on and it appeared to be working as I could see faint lines across the glass where the condensation was disappearing.
Turned the rear defroster on this morning and heard a loud bang. Looking back I realized that back window had spider cracks all over. I did research today and realized that this is a re-occurring problem. This is going to cost $800 on Thursday morning to have the entire window replaced.
The rear defrost has been working intermittently for the last couple of weeks. Last week I was driving home and heard a loud explosion which sounded like a gun shot. I was so startled that I swerved into another lane (luckily there was no oncoming traffic). I pulled over and noticed the passenger side of the 3 panel rear window was spidered. We have a 2010 FX4 supercrew.

Contacted Ford first about rh rear defroster not working. Luckily only had the burnt smell and not the explosion of glass. Being this is the highest number of complaints on this site Ford should really consider looking into this before possibly a child in a car seat gets a face full of glass. As usuall from Ford I received the usual form letter back about not being under any recalls. Vehicle only has 32,400 miles on it. Would like to know the actual manufacture Ford buys these from. Even offered if they were to send me a rear unit I would replace it myself as being a auto tech all my life and send the old unit back for verification.
I allowed my car to warm up. It was approximately 28 degrees outside. I began to drive my car. I engaged the rear defroster. Within 60 seconds I heard a loud bang, similar to a gun shot. Along with a smell of smoke. Then glass went flying towards the front of vehicle. After looking around I noticed the rear window was shattered. The rear window consists of three pieces of glass. Only the passenger (far right side) was shattered. Luckily, there was no people sitting in the back seat at the time. Took it to the Ford dealership, they said the Ford company has not addressed the issue. I was told numerous F150's have had similar problems. Ford refuses to cover repairs.
Rear window defroster/window assembly connection defective, shorts out causing fire and glass breakage. I dropped off my daughter at preschool and five minutes later I noticed smoke coming out of the passenger side rear defroster window behind her car seat. I pulled over to find this becoming a fire. It began as smoke, then spark, and then flame. Fortunately, I had a bottle of water in my truck, which I began to pour on it to stop. It got worse with the sparks, but eventually went out. While trying to distinguish the fire, the "explosion" occurred shattering the rear window. I took this to my local Ford dealer and began to research issue. I quickly found several Ford forums where other people experienced the exact same issue on 2010 F150 Ford trucks. Here's a link to one that helps explain the issue clearly. I posted my experience in post 38...www.F150forum.com/F38/rear-window-defroster-exploding-rear-window-129167/.. I see there have been no reports to you regarding this issue previously. Obviously a defective defroster/window unit causing a vehicle to catch fire is a dangerous issue. But there was no need to push issue further due to their Ford dealer understanding the issue and covering the repair under warranty. I have Ford's premiumcare extended warranty which should cover this but my dealer is seeing only as glass breakage and refusing to cover it under warranty. There would be no glass breakage if the defective assembly didn't cause a fire, and if I didn't have something to put out the fire there would have been far more damage..with cold weather coming, and more recent incidents posted, there will be more instances of this in the near future on 2010 Ford F150 trucks. With the redesign of replacement part Ford is aware that the original design is flawed. Updated 11/05/12 updated 11/07/2012
