While driving to work today, and making a right hand turn, my vehicle completely shut off. That is, the engine died, the power steering died, and the brakes died while the truck came to a complete stop in the middle of the lane. Let me reiterate - the truck completely died in the middle of the road and there was a complete loss of control over the vehicle. Had there been another vehicle, object, or person in front of me, I would have likely collided with them (thankfully the road was empty) research has lead me to find that this is a known issue with Ford and the f150 series from years 2010 to approximately 2014. Fuse number 27 in the engine fuse box is undersized from the factory and melts due to the inability to handle the amperage. I found mine melted after today as well. Ford has "addressed" this issue with a TSB (Ford TSB-15-0137 see attached) which it charges customers for to replace the fuse and wiring for the fuse with a new, up sized fuse and wires. They do not cover this free of charge unless your truck is under warranty. As this is a glaring safety issue that numerous people have reported, I ask that the NHTSA investigate this and have Ford initiate a recall on the affected vehicles, and make the repair free of charge to customers. This issue is a manufacturing flaw and one that has the ability to cause loss of life and property due to failure to control the vehicle. . Read more...

I had my truck towed to auto fair Ford and had to have the fuel pump replaced with $100 extended warranty and the car is a year old. After fixing it they were having issues with it not starting and called Ford to trouble shoot the issue. Today 3/2/18 they called to say a mouse or rodent chewed through the wiring. I have lived I'm my home since 1999 and many cars in the drive way this has never happened before. My brother said the wiring is soy based. I called liberty mutual insurance and comprehensive has a $500 deductible. They will look at the truck 3/5/18 at auto fair Ford in manchester nh. I now have to pay$600 to a vehicle I have owned less then 5 months to auto fair Ford. Seems odd this is happing on a new vehicle.

My Ford f150 experienced a coolant system leak similar to recalls for other Ford models (https://media. Ford. Com/content/fordmedia/fna/us/en/news/2017/03/29/Ford-issues-three-safety-recalls-and-one-safety-compliance-recal. Html). The problem is so bad with Ford trucks around my model year that there is a nationwide backorder of the part to fix the problem. The coolant system's "t connector" was leaking onto my wiring harness and presented a potential fire hazard much like the recall notice for similar Ford vehicles. Simply search "2013 Ford f150 coolant leak" and the t connector problem is at the top of the search results. Ford dealers and mechanic shops are aware of the design flaw, but Ford motor CO will not address it as a recall at this time. This needs to be remedied. The leak was occurring when the vehicle was running and in motion.

As the smoke progressed, the driver soon observed flames and melting plastic dripping off of the hvac box. The driver immediately pulled over, opened the [passenger door and extinguished the flames with a 10 bac fire extinguisher. When the vehicle was brought into the mesa county fleet repair facility, we noticed the heat source originated from the blower motor and resistor area of the hvac box. The electrical wiring has melted insulation and no fuses appear to have burned.

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.

Failure Date: 05/13/2015

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.
