Model year 2009-2014 f150's have an issue with fuse 27 under the hood getting hot and melting. Fuse 27 is for the fuel pump relay. This causes complete loss of power while driving or a no start situation. Ford has issued a TSB for this issue, but in my mind it should be a recall. If the fuel pump stops, you lose all power no matter where you are, even if in heavy traffic on the interstate. This could also be a fire hazard if the wiring gets hot enough.

After having my truck fail to start several times I discovered it was a "fuse 27" issue with the truck. This issue is so prevalent that the Ford dealer knew the issue by name as soon as I described it. The fuse, located in slot 27 of the main fuse panel was severely burned and charred from an overload issue that causes the fuse to burn in its socket instead of tripping like a fuse is designed. After researching the issue, I discovered this is a known issue to Ford (TSB 15-0137) and hundreds, possibly thousands of Ford F-150 vehicles are affected with this issue. This issue is a potential fire hazard to the vehicle, or could cause loss of power at highway speeds. Ford is choosing to release a TSB and a repair kit, and charge customers to fix their faulty wiring in their new vehicles instead of a recall or warranty coverage of a known issue they are not fixing. This is dangerous and irresponsible on Ford's part.

Fuel pump relay fuse (#27) will either blow or melt in fuse box. Replacing fuse will only fix problem temporarily, as melted area in fuse box will cause new fuse to not make consistent contact, leading to vehicle not starting when hot, or even engine cutting off while driving, causing really bad safety issue. Very difficult problem to fix, as dealers either give you the run around or want to replace entire fuse box and engine wiring harness which costs about $2000, parts and labor. 'solution' is to find wire to relay in fuse box, very difficult, and splice in an inline fuse. Have had mechanic and towing fees over $1000 so far, and still only have a bypass fuse installed. Local dealer was aware of the issue, as they see this problem all of the time, was told to call Ford, which had never heard of the problem. Another Ford owner next door has the exact same problem.

I have had several electrical failures on this vehicle after buying it new in October 2007, in October 2009 the cigarette lighter stopped working was repaired and again months later stopped working. The windows stopped working a total of six times with three of those being this year. I have taken my car in to be repaired a total of three times this year alone and the last time , about four or five weeks ago I instructed the worker to just let the windows up and disconnect them after being told that I needed a complete new wiring harness which were no longer available. I was told that the wiring was brittle and that this was a common problem with the f 150. I feel that this could pose a danger in an emergency escape situation as well as other problems. This problem also involve the electronic locking system which is a great safety hazard, I can get no real response from Ford.

Wiring harness on 2010 Ford F-150 4x4 burns up at fuse box. Original harness was replaced by dealer in 2013. Second harness burnt up at fuse box after 16 months. Waiting for new harness at present time. It is the fuel pump connection that is burning up in the box by the fuse. When the harness burns through, the vehicle automatically stops, even while in motion. This constitutes a safety hazard as no notice occurs before burn up. No warning lights appear on dash to warn of this. Nothing has been done to correct the failure, other than replacing the wire harness that is burning up. They have done nothing to correct the reason for the burn up. All that has been done is replacement of the part that is damaged. . Have been waiting for over a month for parts. Other vehicles at the dealership are also experiencing this same issue.

Shock upper mount simply fell off causing driver side rear shock to drag ground. After further inspection also noticed at the location of the rusted out mount location that the rear wiring for the tail light were severed causing truck to now be stuck in park. Also while inspecting noticed rear frame is simply falling apart and other areas throughout the frame are weak as well. This is a huge safety concern after doing research I am finding many accounts of the same issue online but no manufacture recalls. Why isn't Ford doing anything about this issue? I've never seen frames do this. Truck needs full frame replacement.

We have had our 2005 F-150 king ranch for about 10 years now. Today (Feb 10,2015), my wife and our one year babe were heading to the post office the truck displayed a message reading "engine failsafe mode". The truck lost all power, no steering, and it stall on the highway going about 65 mph. Luckily, she said there were vehicles behind her and she pulled it over with no steering and the engine dead. My wife then sat on the highway for about 10 minutes and tried to start the vehicle, which started and there were no "engine failsafe mode" on display anymore. Know with-in the last year our truck has had the check engine light and the abs light has come on and off every other month. I have checked the fuses and had replace a few but at time it is not the fuse. I've had the interior dim in and out and at times it does not work at all. By reading the f150. Net forum found out the a wire that splits into two wires was corroded on the passenger side floor board, it seems that condensation or water come in and stays in that pocket were that wiring harness goes thru. I am now terrified that truck will shut off on the highway again with my family and I in it. This seems to be a life threating problem. I have read thru some forums and it seems that people have called the Ford dealership and the service department claimed they have never heard of this problem, but can work on it if they bring it in. But that Ford claim that they fix the problem and the people says that the problem still exist. Hope some one can help or assist us in fixing this issue not just for our family but for others too. Sincerely airborne paratrooper! aatw!.

On the morning of 12/29/14, he had a heavy frost so I used my rear window defrost on my drive to work. Drive was approx. 10 minutes. When I got out of the truck at work, all glass was ok. When I got back in truck to leave work, I looked in rear view mirror, I saw that the passenger side of the three piece rear window was shattered. The glass stayed in the frame and did not fall out. I had to spend over an hour on the phone with my insurance company just to file a claim, and it took the glass company two tries to install the new rear window and rewire it to make it work again. Ford knows there is a problem because they have changed the design on the window along with the wiring to the window. Why will Ford not step up and at least admit there is a problem with the rear defrost and offer to fix it.

The rear door wiring harnesses are under/poorly engineered for normal usage and durability and are subject to premature breakage specifically where the body meets the door resulting in multiple exposed wires causing first and foremost the dangerous potential for vehicle fire as well as inoperable door ajar sensors, electronic locks, window control and interior lighting.

Vehicle once when first bought shut down during rain conditions when trying to excel. It was like you ran into a wall. Ford then said it was a wiring harness problem. It continued missing at times over the last two years. The same thing happened again in December while trying to pass a vehicle and it was again during rain conditions and just shut down in the road. We took it into the dealership and they said it was TSB 13 8 1 and made repairs. Vehicle now does not run right and gas mileage has dropped by at lest 2. 5 mpg. Noticeable power loss. Vehicle is the Ford 3. 5 echo boost. This is a big problem for consumers who want a truck and expect power with good mpg but should not be afraid to drive or get a supposed fix that's not what you have purchased. These situations will result into some very bad accidents. I cant imagine pulling something and this happens. Bottom line consumers deserve safe reliable vehicles. We love Fords and I hate I am having to complain but this is a real big problem. Please investigate. Thanks!!!!.

While I was driving I turned my rear defroster on and about 5 min later I heard a load bang, looked around to see what it was and saw the passenger portion of the rear window was completely shattered. There was no impact on the window are clue to why it shattered. So I looked online and found this to be a common issue with the 2010 f150 trucks with power rear sliders. My daughter's car seat is directly under that window! Ford denied any knowledge of this issue and insisted they were not responsible and wouldn't cover repairs. I then learned that Ford has changed the wiring design for this window, a design that keeps electrical surges from over heating the defroster. My concern is that a shattering window poses a huge safety issue and Ford should be held accountable for their failure to keep their customers and more importantly the children of those customers safe!.

On a ~50 degree morning, I turned on my rear defrost when my rear window (passenger side) shattered about 5 minutes after I turned it on. This is a 3 piece window as the middle is a slider on the pickup, only the passenger side broke. I was driving with no other cars around as there must be a short or faulty wiring in the rear defrost. This was not covered under warranty by Ford and seems to be a common problem.

Rear lights, including brake, turn signals, and hazard lights quit working. This issue can be found on many online Ford F-150 forums. The steering column wiring is too short, and breakage in the wire, or connectors can occur with the tilt steering mechanism. The tilt steering mechanism and short wiring has caused the connection to break inside the steering column trim on our vehicle, which caused the lights to stop functioning properly. I inspected the problem, and found the connector can move freely. I feel this is an issue since I am able to locate many others that have had the same issue from 1997 up to 2001 Ford F-150s.

I own a 2004 Ford F-150. In 2012 I had my e-brake light start flashing at me. I brought it into the mechanic and had them look it over, they said they couldn't find anything wrong other then the wiring under the dash was probably bad, so I brought it to a brake specialist and they said the same thing, nothing wrong with cylinder or brakes, that it was the wiring under the dash. I'm truely not safe using my e-brake as I'm not sure if it is working or not. My interior lights started coming on also when I would turn on my headlights, everyone knows you shouldn't have the interior lights on while driving at night anyway. I have read several articles where other Ford F-150 owners are having the same problems. I think this needs to be looked into and a recall should go out.

Vehicle lost all power (in dry climate), including steering, and brakes at approximately 50mph. Came to a stop using the emergency brake. Had two near misses while attempting to come to a stop. Vehicle had to be towed as the ecm (engine control module) was no good. Had prior misfires in engine, which Ford had diagnosed as a bad head valve. After rebuilding the heads, the problem continued (while under use in dry climate). Incident occurred, at which point the vehicle had become disabled. 2nd Ford dealership diagnosed as "electrical problems" which had allegedly caused the vehicle's ecm (engine control module) to short out. No more than 500 miles and/or 3 days after replacement of the ecm and fixing of unspecified "electrical problems" (and in moist climate), vehicle would have periodic misfires which would on occasion be so severe so as to drop all gauges on dash to their "off" positions, but with the engine still running (under stress from supposed misfire which would shake the entire truck). On two later occasions, while idling at a stop light the vehicle would repeat the same condition as with the initial incident, where the vehicle would completely shut-off, with exception that on the repeat occasions, the ecm was still functional and I was able to restart the vehicle. A 3rd Ford dealership was unable to diagnose exact problem but suggested replacement of coils followed by wiring as a possible fix to the misfire. I removed the vehicle to a dry climate and replaced all plugs, coils, and boots for testing. Vehicle successfully functioned under dry, moist, and snowy climates afterwards. Continues in operation and is currently at +/- 155,000 miles.
