Power rear window glass has factory flaw causes rear window defroster and heated mirrors to become inoperable. There has been hundreds, if not thousands of cases of this issue. Ford will not issue a recall. They do not cover it in their top tier extended warranty programs. I was quoted over $1000 to replace whole back glass to rectify. Ford has since changed vendors for the complete back glass unit and still no recall.

In May 2015 my 2011 Ford F150 3.5L ecoboost began making a buzzing noise in the front left fender well under the hood. From that time forward the truck makes the noise upon start-up. Once the vehicle runs for a while the noise seems to fade away but returns upon restart. A technician tried to diagnose the noise at a local repair shop but to no avail. The noise has gotten worse which prompted me to take the truck back to the repair shop to diagnose again. This time I did some research on the matter and noticed that there was some concern about the vacuum pump in some of these model trucks. Upon picking up my truck the technician informed me that he thought it was the vacuum pump and that I should take my truck to the dealership to have them diagnose the problem and that the part is only available through Ford at this time. I made and appointment with the Ford dealership with the service manager about the noise. He was familiar with the problem and said that 9/10 times the vacuum pump is the problem. He explained that Ford had switched vendors for the part and redesigned the pump in newer models and issued a (tsb) regarding the pump. Since my truck was just outside the warranty period he said I would have to pay for the repair, which was quoted at more than $900. The service manager told me that the part was on back order until mid August 2015 and that I should schedule to have the repair completed then. I asked if there was a safety hazard associated with continued driving and he said, "no, the only thing that could happen is you could lose your brakes or possibly 4 wheel drive, but you'll notice that the brakes are heavy if its going out completely." I feel that Ford should be responsible to replace the defective part that they acknowledge as a problem and have redesigned, and which can cause brake or 4 wheel drive failure putting myself and my passengers at risk.

This model F-150 has a known problem in that the electrical defrost on the rear window stops working. The repair is a $750 new window that Ford refuses to fix, nor guarantee once they do fix it. It is happening to a lot of F-150 owners, and this is a safety concern, as the window will remain fogged or snow covered in winter driving months. Again, Ford is aware, as this problem has affected many F-150 owners, as verified by a google search.

While traveling a long duration at a consistent mph, low RPM, and low turbo boost pressure I began to climb a hill where more acceleration was needed to maintain mph. At time the vehicle rapidly slowed, engine light cam on, tried to add throttle to stay out of the way of approaching traffic but just continued to slow. This happened while traveling from las vegas Nevada to reno Nevada. I replaced the ignition coils and that solved the problem only to have it happen again in less than 5K miles in the same driving conditions

While driving at 65mph on a highway in ga with my rear window defroster on, with an exterior temperature in the mid 50S, I heard a very loud bang which I initially thought was a rock kicked up by the vehicle in front of me. When I reached my destination, I found it was the passenger side rear window panel that had shattered due to the defroster overheating and was still intact because of the factory tint applied to the involved window. It's obvious the defroster was the cause because the spider webbing began at the corner/base of the window where the heating connections are in place and now my rear window defroster does not work when I attempt to activate it.

Started the truck in the morning (temperature was 45) and the battery light came on. Took it and had it check and had the battery replaced. After the battery was in, they ran a test and said the alternator was charging too much and the light will come on again. Sure enough after a few seconds, the battery light came back on. Took it to the dealer (apple Ford in red lion, pa) I purchased it from and they said the alternator is bad and charging too much. There stated that there are no after market alternators for this make and year. So after paying $1055 for a Ford brand alternator, the truck was fixed. That is way too much money for an alternator. It is an outrage!! I checked around and I cannot believe that the price of this part is actually this expensive. I asked if they have heard about this problem, and the answer was no. I have been a Ford owner most of my life, but this may change my opinion on Ford trucks for my next purchase.
