I was getting ready to get our of my house with my son. While we were locking our seat-belts, I heard a loud bang and when I turned, the back right rear window behind my son's head was all shattered.nothing hit it as the truck was standing with the windows facing my house, it just exploded on its own.

At a stoplight I activated the rear window defroster. After approximately 30 seconds I heard a sharp large cracking sound. Upon investigation I found the driver side rear window was shattered but still in place. No signs of chips from inside vehicle or outside were seen before the incident. After getting back inside the vehicle I noticed the rear defroster was inoperable.

My wife and duaghter were driving down I-75 when she heard a couple of chimes followed by a message to safely shut down. The truck lost all power at that point and the engine turned off by itself. She wjoshuaas lucky she was already in the right lane and was able to get off the interstate prior to anything too bad happening. I had already done some research and found Ford has had an issue with the 4 egt exsensors shutting the vehicle down to protect engine. This is a very serious safety issue if you consider I could have been towing 17,000lb trailer behind me when this could happen. I strongly feel that Ford needs to address the bad sensors quickly before something worse happens. My truck has had no modifications nor chips in it, sensors go bad and kills the engine. Only 34,000 miles on it.

When taking off from being stopped there is a thumping, clicking, snapping type sound coming from the rear of the truck. Not only does it make a noise but you can feel it. Truck was taken into the dealer for inspection and dealer could not find out where it was coming from. Updated 4/24/2015

Major safety issue with F150 ecoboost trucks. Hundreds of owners with this issue: www.F150forum.com/F38/2011-55-60mph-shuddering-possible-fix-128636/index145/ while taking off from T-intersection and turning left crossing oncoming traffic the truck started to take off then lost all power for approximately 3-5 seconds. This left my family and I sitting in the oncoming traffic lane on a blind corner. The truck did not die (I thought it did), I mashed accelerator to floor and truck did not respond whatsoever. My wife was screaming frantically at me asking what I was doing while I attempted to get the truck to move out of the oncoming lane. After approximately 5 seconds the truck regained power and accelerated normally. This has occurred 3X now and I am afraid to drive the truck but do and my wife will not drive it at all. Several other owners of the ecoboost F150 have experience this precise problem. Ford has done nothing to address the problem and has promised a fix for the last 3 months. While the truck has other major issues this specific problem is going to result in deaths. It's not a matter of if, but when.
