Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Rear glass window on 2011 F150 with power slider- driver side back quarter glass shattered, while driving. Rear defroster was on. I have researched this issue and have seen many complaints reported online. I am glad my children weren't in the back seat at the time this happened and it stayed in the frame and did not blow out/into the rear vehicle passenger area

Warming my truck up to leave for work this morning. Turned on windshield defroster and rear window defroster to remove heavy dew. Rear defroster turned on for about 10 seconds and shut off by it self. While driving I noticed it had turned off, pushed the button again and it did not turn on. About 2 minutes later I heard a loud "pop" and looked in my rear view mirror to see that the right rear window had shattered.

After rear defrost was activated while driving to work in the morning there was a very loud bang and the drivers side rear window broke and spidered. This occurred on April 15 2016. Temp was about 35 deg F. note rear window was replaced once already in 2013 for the rear defrost not working.

Rear window shattering due to rear defrost temp in the 30's, started my truck, turned on the front & rear defrost for a few minutes before leaving the driveway. Heard a loud pop from behind me. My drivers side rear window was shattered. I immediately turned off the defrost, and turned off my car. Good thing I hadn't put my child in the car seat before the defroster caused the glass to shatter. I never put the vehicle in gear, stayed stationary.

On March 24, 2016 I started my vehicle and activated rear defrost as there had been some light snow build up. Within a few moments I was traveling down the road at approx 45 mph. About two minutes later I heard a loud bang that sounded like a gun shot. This was a bit startling and my reaction immediately caused me to swerve into the adjacent lane of traffic. I quickly pulled to the side of the road and noticed that the right rear window had shattered. The slider and left side did not break, only the right. This could have turned out much worse had there been a vehicle driving next to me at the time. Very scary experience and potentially very dangerous.

Passenger side rear window exploded due to the window defroster. This seems to be common among F150's with a rear slider window. This happen on the way to work one morning. Speed 35 mph on smooth pavement. There was frost on the window but the light on the defroster was not on. Heard a loud bang and did not immediately notice the broken glass until later in the day when the sun defrosted that glass. No response from Ford customer service

I turned on the truck with the remote starter. This is apparently tied into the auto defroster on the back window. As soon as I got in the car and started to drive the back window blew out for no reason. I did a search on the web and apparently this is an extremely common problem. The noise was so loud I actually thought someone shot out my window!!

Rear passenger side of rear slider window shattered when operating defroster when approx. 27 deg. F. no impact, but loud gunshot like sound and glass was simply shattered while driving.

Rear defroster quit working for awhile. Turned on the truck today. It was about 26F outside. I tried to turn on my rear defroster button again. It did not turn on. I was driving down the road about 35-40 mph. Heard a loud bang, noticed my drivers side rear sliding window is now shattered. Called the Ford dealership they had no idea of this happending. Called Ford customer care, they had no idea of this either. It seems like everyone else on the internet knows of this issue except Ford and their dealers.

Driving straight on highway with no other vehicles around, back glass spontaneously shattered with no warning and nothing touching it. Suspect an already faulty rear window defroster heating element on power sliding rear pick-up truck window is at partial fault. Smelled of burning electrical in cabin just prior to breakage. Poor window quality and heating element at further fault. Also feel like I had tiny glass particles all over me as well.
