I own a 2011 Ford F150. Driving home from work last week in the dark I just got onto the highway and I heard what sounded like something hit the bottom of the truck or a gun was shot. Didn't know what happened, I then noticed the rear defroster light was not on I went to turn it on and it did not go on that is when I looked at my back window and noticed it was shattered on the passengers side. When I got home I went on the internet and saw that this was happening a lot so I contacted Ford about the window and they said that they checked there resources and verified that my vehicle is not involved in any recalls or customer satisfaction programs at this time and it must be inspected by a Ford dealership to determine the cause of any symptoms my vehicle may be experiencing. Went to Ford dealer they said that I should just go to a glass specialist to have it fixed. So I took it to a glass specialist and they said they have replaced at least 14 rear windows on Ford trucks because of this problem in the past couple months, I should call Ford and complain and hang on to my receipt.

2011 F-150 FX4. Service advancetrac warning light displays. It comes on when I start up the vehicle stationary. The turn signals stop working, too. The next day the light will be off. Appears to be a common manufacturing defect that should be a recall just like on the 2014 F-150S as it is a issues of safety.

At high speeds on the interstate vehicle floats to the left and it is hard to straighten, almost as if there is no power assist.(I understand Ford recalled some but not all 2011 F150's for a steering rack replacement (started around 4 yrs/ 55,000 miles 3. transmission takes about 10 seconds to engage into reverse upon starting in the morning or on cold days when vehicle has been parked for mare then say 5 hours started around 6 months/ 6,000 miles.

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.

I own a 2011 Ford F150 FX4. While my truck is parked and engine off and doors locked the dash backlight stays illuminated and drains the battery completely. Z this begin about 6 months ago. Around 55K miles on it. I have to unhook my battery when I get out of the truck to prevent my battery from draining. I found if I unplug battery for about 10 min I find the backlight will not come on for about days. Also, my drivers side back door will not unlock remotely or inside the car. It can only be locked or unlocked manually.

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.

The contact owns a 2011 Ford F-150. While driving approximately 5 mph and depressed the brake pedal to stop at a stop sign, the anti lock brake warning indicator illuminated. The brake pedal was pumped and the vehicle slid into the intersection. The failure recurred on two other occasions. On the third occasion, while driving approximately 30 mph, the brake pedal failed to respond when depressed. The brake pedal was pumped as the contact slid into an intersection. The contact clipped the rear of a Jeep that was traveling approximately 60 mph, causing the Jeep to flip over twice before landing upright. The contact and the driver of the other vehicle sustained injuries that required medical attention and were transported by ambulance. A police report was filed. The vehicle was towed to a body shop, but the failure was unable to be determined. The damage to the vehicle was repaired. The contact also stated that when the windshield wipers were powered off, they would independently swipe across the windshield approximately every ten seconds. The contact stated that the fuse had to be removed so the windshield wipers would disengage. The manufacturer was not made aware of the failures. The approximate failure mileage was 59,000.

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

F-150 4WD 8-cyl

  • 75,662 miles
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.
