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.

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.

Failure Date: 05/12/2012

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.

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.

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.

Pulled my 1998 f150 4x4 XLT supercrew into my driveway, turned everything off and exited the vehicle and entered my house. Three hours later, I went to gain entry to my truck and when I opened the door, smoke billowed out. It melted my instrument panel from just above steering wheel to the drivers door. A wiring harness was on fire and burnt clear to driver side rug. All the coating was burnt off the harness and was in flames. I burnt my fingers trying to get it out. There were sparks coming from it. I then disconnected the battery terminals and got the fire under control.

Pull gear shifter down to d1 and smoke and fire came out of the steering column: all of the instrument lights went out and the truck was unable to use the overdrive function. Replaced several fuses and tried again with the same results. I dismantled the steering column and noticed that the wiring harness is two short and routed around the steering column causing it to break everytime the truck is put into d1. Ford motor company nor any auto store have any parts to repair the problem. The truck is still available for inspection. I took my truck to a Ford dealer and they did not have a fix for the problem. They recommend that I not use d2/d1/overdrive.

There was an electrical fire in the wiring harness connected to the master cylinder (brakes). No damage was done due to quick reaction but it left the brakes without power and the truck without brake lights. The problem is believed to be related to the "switch fire" problem that resulted in a wide-spread Ford recall. The vehicle in question is a 1997 Ford F-150 4x4. Truck was purchased from lease-holder and full warranty was transferred to me. I have received several recall notices but not the one associated with this problem.

I went fishing one early morning and I stopped for gas and noticed that my lights would not turn off. I normally keep the switch in the auto-detect mode. I switched to off and they still would not turn off. After getting to the dock, I turned off the motor and locked it. My F-150's headlights would not turn off and would blink on and off. The switch would not work, nor did locking the vehicle turn off the lights. I expected the battery saver would activate to turn off the exterior lamps. It also failed. The battery died and I had to be towed into the dealer. Dealer states it was a wiring harness (#12, #160 and #161) that shorted a relay and killed the battery. The parts were not covered under warranty. Parts and labor were $612.

: the contact stated while driving 10 mph, a burnt smell was noticed. Upon inspection, a red wire under the driver seat was on fire. Also, the electrical wiring harness for the power seats and seat heater was inoperable. The vehicle was taken to a service dealer who determined that the wires rubbing against the seat frame caused the fire. The dealer replaced the 3 wiring harnesses connected from the dash to all seats in the vehicle. The manufacturer was alerted and denied the claim.

Mice have eaten through the wires to my fuel sending unit. Several months ago the did ate through many wires in my engine compartment. It is my view that this presents a severe potential for fire which could easily injure or kill. These have been expensive repairs that could have been prevented if Ford had not skimped on protection of their wiring harnesses. I can't believe that Ford that claims their vehicles are built Ford tough can't be protected from a small rodent. The first incident in August of 2005 cost over $1500 to repair and this second incident is estimated at approx $500.
