Ford F-150 owners have reported 125 problems related to wiring (under the electrical system category).
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.

Broken wires in the wiring harness going to the driver's door. Causes automatic windows to not be able to roll down, radio does not turn off when key is off and door is open, keyless entry keypad doesn't work, folding mirrors do not work.
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 back right drivers side rear window shattered due to the wiring or the rear window defroster. This has happened twice on 12/10/14 and 3/27/15. This is a known defect that Ford has not addressed yet.

My heated seat drivers side became very hot - causing small red spot on my leg. Pulled seat cover which had become distorted and discovered heated seat element had shorted out melting copper wiring and burning a hole in foam seat cushion. Ended up replacing element and leather seat cover on my own just parts cost nearly $600. Contacted Ford customer service three times with no response. Checked google search and there are many people having issues with these elements. I saved cover, and element and have pictures available.

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.
The contact owns a 2010 Ford F-150. The contact stated that the air conditioner suddenly failed and a burning odor was present. The contact discovered that a plug attached to the resister wire had melted. The failure occurred on four separate occasions. The contact replaced the plug, but the failure recurred. The manufacturer was made aware of the failure. The approximate failure mileage was 130,000.
Filed a complaint eariler in the year about the electrical problems, and finally received a call back from the dealer. I took my 2010 Ford F-150 in and it was determined the wiring harness was defective. Well great. . . 900$ to get if fixed. Not covered under warranty. Truck will not start without it. Wow, I use to love Fords. . . Never again will I purchase a Ford of any kind. Thanks.
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.

Electrical wiring on the frame under drivers door wires are corroding . Many of the 2007 Ford f150 has under lay wires going to the fuel take to the computer under the hood.
I own a 2012 f150 platinum truck with an ecoboost engine. We purchased the truck new. I was on the interstate and was trying to pass a slow moving car. The vehicle went into overdrive and began to shake. I pulled over to the side of the road. The check engine light was on. I turned off the vehicle and waited a moment. When I restarted the truck I drove to the nearest dealership. It did this again twice on the way to the dealership. They said that the wiring was at fault and replaced the defective part. Then at 34,470 it occurred again. We were on a highway about to pass someone when the truck began to shake and the engine slowed and would not accelerate. The dealership suggested that we use a higher octane fuel and said they could not find anything wrong with it. This problem occurred eight additional times. Then at 82,200 miles we were traveling up hill and heard a loud boom. We had it towed to the nearest dealership and found out that a connecting rod had broken causing two holes in the engine. We had to have the entire engine assembly replaced along with two new turbos. Ford would not cover because the engine had 82,200 miles and the power train warranty ended at 60,000 miles.

This truck has only been used three time in five months. It was parked on a parking pad unattended for three days an 10 hours. The main electrical wiring started a fire inside of the truck on its own. If it had not been found at 3:00 am it would have most likely kill two people in their beds. ## VIN passed ## Ford F-150 lariat 2004 ## updated 03/12/12.
I have owned this truck since 2004, no serious issues. This past Friday I noticed power was still going to my truck when it was turned off. The power accessory relay was clicking vigorously then stopped, no power inside my vehicle. I started the truck and everything worked except for the radio. I went for a drive than and then the reverse lights came on the door buzzer was going off, as I went to stop I heard a grinding noise occur than stopped. Was able to get it home. I have 30 years of mechanic experience and tried to find a possible short. When I removed the passenger side rocker panel I found the harness covered in rusty water. Now doing research on the internet, I have seen hundreds of people complaining about this issue, that Ford wont cover. It turns out many people had to have wiring harness replaced costing thousands. While conducting my research I have found out water is leaking through the windshield the rear window and wiring harness that travels through the firewall. Please help, Ford will not admit to their mistake.
This is very disappointing to have to experience so soon with a brand new truck. The location of this wiring harness is in an area that unless you have side steps and maybe even then, is not protected. Even then the way the wiring harness comes out from within the wheel wall makes no sense. I'm attaching a few pictures so you can see what occurred. Luckily, someone saw the wire dragging and told me before it was too late. I put up the harness and taped it to hold it up. This could have had a horrible outcome had the wires continued to shred or make contact with one another.
2005 Ford f150. Consumer states engine shuts off and vehicle continues to go into "fail safe mode" the consumer stated there were times when the vehicle would re-start, and other times it wouldn't. The consumer stated several components such as the fuel filter, catalytic converter, fuel pump module, throttle body, and crankshaft position sensor were replaced to try and rectify the problem. The engine began to misfire and the check engine light illuminated. The consumer stated it was finally determined, the casing on the crankshaft position sensor wire had rubbed through and was shorting out on the ac line running along the right fender well. The consumer stated at some point when his vehicle was being serviced at the dealer, a cover was removed from the far left wiring harness at the pcm, which permitted water to run down the inside of the wiring harness and shorted out the connector. Jb.
After starting the truck, and having seemingly normal operation. It started to run rough and had a marked loss of power. The check engine light did not initially illuminate, giving no indication of a serious problem. Thinking this was a temporary problem, we continued home. The next day my wife took the truck on her normal daily routine. She notified me later that the truck had gotten worse and that it was very rough and low on power, to the point of making merging very dicey. We took the car to the dealer for diagnosis and they found a wiring harness had chafed through due to a riding condition on an air conditioning line. This affected coil number 4. The dealer repaired the chafed wire and returned the car to service. The ironic thing(or disappointing, depending on your perspective) was that we had the car in for a recall campaign for a chafing wire in the airbag system.
May 19, 2011 at around 4:20 am we were awaken by our neighbors that our truck was on fire. Our 2001 Ford f150 was on fire, an explosion had made a huge hole in the hood on the front of the driver side. The truck had last been driven the morning of may 17, 2011 and had been sitting in our driveway since then. The firemen said the fire was due to electrical wiring. We always kept up with all required maintenance. We had no idea of the problems Fords were having, we now only have one vehicle to get around and the worst part is that it's a 2004 Ford f250 which could also be a recall vehicle. Our income is very tight because my mother is very sick and we are sending money for her medication and expenses, we have no way of getting another vehicle. Our Ford f250 is a diesel and diesel fuel is very high. Someone please help! not sure what we're suppose to do or if Ford will be responsible.
