Vehicle suddenly lost its ability to monitor the blindspot traffic the stability and traction control went off tire pressure monitor field along with the airbag and seatbelt restraint. Take him to the dealer and was told there is a wire that runs between the spare tire and bumper a trailer hitch assembly that often chaffs. They had replace many recently. The loss of traction control happens to me during a rain storm and caused me to loose control of my truck. While I regained control and prevented hitting a guard rail, it was serious. This is no fault of my own it's an installation and assembly issue, and safety concern. As a 1st responder I depend on my truck, and must pay the $500 to repair a bad wiring installation on a 2017 truck, that could have cost me my life.

Driving eastbound on I-10 at 75 -80 mph, on a mountain, suddenly advanctrac fault warning and engine power lost. Vehicle entered limp mode. I was forced to �limp� on the shoulder to reach a safe area to stop with cell service and wait for a tow truck. This was a very dangerous situation. Semi traffic at high speeds were blowing past very little shoulder space to navigate. At each guard rail I was forced to stop - wait for a break in traffic- restart and pray for enough momentum to get around the area. I finally limped into wilcox az and contacted Ford roadside assistance. The vehicle was towed 74 miles to smith Ford in lordsburg nm $280. Fra advised that due to covid 19 no personal transportation is available. No alternate transportation is available in wilcox az. Smith Ford service does not open until Monday. Another roadside service $205 put computer on it. Code p2112 throttle actuator �a� control system stuck closed. Pyramid roadside service found damaged wiring behind accelerator pedal and loose pedal. I had to walk alone in the desert to find a hotel. I eventually walked another 2 miles pulling a suitcase to a grayhound station to phoenix Sunday (274 miles). I will contact dealer tomorrow. Ford has been aware customer satisfaction program to replace defective etb 2015 & 2016 f150. I purchased may 5, 2019 and was not made aware of potentially dangerous situation. No recall was issued for this dangerous defect. Not only could I have been seriously injured on the interstate, I was put in very high risk situations both due to covid 19 high risk in this part of the country but also my personal safety being alone without transportation in an area with limited resources. Thus far I am out of pocket $800. 00 and do not know what additional expenses I may incur until my truck is repaired. I live in papillion, ne and have a long way to go to get back home.

Very dangerous wiring design. Wire harness too close to engine exhaust manifold, turbo - as result - melted wires. Tin foil did not protect from melting. Happened while driving on 75 interstate - vehicle looses power steering, cruise control and throws faulty overheat. Contacted manufacturer about it - was given run around.

I stopped while pulling a trailer, fueled my vehicle, hopped back in and the trailer brakes were on constantly. I disconnected 7 way plug and trailer brakes released. I tested trailer braking output at the 7 pin plug and the brake output was stuck on. I turned the gain down to zero and it was still staying on. I checked the trailer for a short and all check showed trailer wiring as ok. I found on an f150 forum many complaints of the same thing happening to 2015 and 2016 f150's and dealers replacing the trailer brakes module and the tow module.

Ford F-150 2018 super crew cab 1st water leak inside of our truck cab created a mildew smell due to wet carpet padding and carpets. Water saturated electrical wiring under the door seal protectors on the right-side of the front and rear doors. First noticed a problem driving and applying the brakes we heard a water sloshing sound on the right side of the truck. Indications of water in cab and saturated carpet's and wiring went unnoticed due to weather tech full floor mats. We contacted Ford corporation online and they advised for us to take it into our dealership to be assessed. Our dealership made an appointment a week out, so our truck sat in our garage for an additional week. We used a shop vac and sucked out as much water as we could and left the door windows down to help dry out the interior. The dealership removed and reinstalled the trim panels with silicone sealant on both doors on the right side.

While diving onto an interstate on ramp, the back glass shattered. Nothing struck the glass, it just broke. When the window was replaced, it was discovered the rear defroster wiring had burned both on the window and in the truck. The rear defroster overheated the window and caused it to shatter. It nearly started a fire.

After starting vehicle, could smell electrical wiring burning. Couple days later rear window with defroster wires melted. Causing window to over heat and break. Window repair person at safelite indicated we are luck truck didnt burn up. He showed us the melted wires.

Truck suddenly loses power, electrical systems fail. Repaired multiple times by dealer diagnosing wiring connection fail under seats. Continues to fail. 5 times in shop since 2016, no longer under warranty.

Corroded body control module and wiring. Ford technicians unable to diagnose cause. Caused vehicle to go into limp mode while driving in an unsafe manner.

Tl- the contact owns a 2016 Ford F-150. The contact stated that after turning the rear window defroster on the rear defroster wiring began to smoke and moments later the rear window shattered. The vehicle was taken to the local dealer five star Ford(6618 ne loop 820, north richland, TX. ) who diagnosed that the defroster wiring was faulty and needed to be replaced. The vehicle was repaired and the failure was remedied. The manufacturer was not notified of the failure. The failure mileage was 32,000. Jft.

The tailgate opens on its own randomly while parked and when moving. This first started happening in the fall of 2018 and I still on going and happen to me again this weekend 1/14/2020 Ford had issued a recall for this issue on 2017 and newer trucks but mine is not listed in the recall. How do I get it added to the recall to fix this safety problem. The recall covers f-250, f-350 and f-450 trucks from the 2017 through 2019 model years. All the trucks have electric tailgate latch release switches in the tailgate handle. Ford says water can get into the electrical wiring and cause a short circuit, activating the switches and releasing the latches. That could allow loose cargo to fall onto the road.

On the 2012 and 2013 model year f150 with rear window defrost it is very common for the electrical wiring or connection to fail and literally blow out the back window. It also affects the heated mirrors if the truck has that option too. When the rear window blows out it can literally blow holes put of the glass. With kids having to ride in the back this is not safe. The rear defrost will work fine or malfunction a couple times and then will eventually fail and break/blow the window out. It is a very well known problem that Ford is doing nothing about. I've contacted Ford and they refuse to fix it.

The fuel management system blew the fuse. I looked online and saw where many people have had this happen and Ford has a service advisory issued for this problem but charge the owner with making the correction to the defective wiring. They do not simply replace the Mini 10 amp fuse but instead replace a part of the wiring and relocate it to a standard 20 amp fuse. When I explained my concern about engineering a fuel management system for a 10 amp rating and switching it to the 20 amp which could allow other parts of the system to overload he basically told me that Ford had decided this was how they would fix the problem but now I have the concern other components of the system failing and sure enough it was less than two weeks later the fuel pump driver module failed causing my vehicle to stop running. The service manager also told me I was lucky as he had seen total melt downs of fuse panels from this defect. This has cost me $805 in repairs due to a faulty wiring design. The vehicle was stationary at the time, once in a parking lot and once in my driveway.

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...

Battery won't if power from time to time after replacing it with a new battery. Back door says it's ajar even when it's not, I did get that repaired after that my radio stopped working checked all fuses. Lots of wiring issues.

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.

Engine fire. A strong smell of burning, electrical wiring order started coming from the a/c vents, I soon noticed smoke coming from under the hood. As the truck slowed to a stop and I guided to the side of the road, open my door, I could see the flames rising and growing larger. By the time I got off the phone with 911, I heard the first blast. In less than 5 mins. Later a larger, louder blast happened. Not long after that, the whole front end was completely melted.

Purchased used 2016 F-150 in oct 2017. Shortly after purchase tailgate would randomly open while vehicle was in motion. Power tailgate would also open when key fob was used to lock vehicle. Tail lights would also illuminate brightly as if brakes were applied when they were not when vehicle was in motion. Other times tail lights would flicker on and off when vehicle was in motion. When computer was scanned no trouble codes were found. Eventually after several trips to BMW dealership in spokane wa where vehicle was purchased vehicle was taken to wendle Ford in spokane wa. At wendle Ford technicians found extremely frayed wiring harness in area at rear of truck where bed and frame meet. Wendle tech's said that they had never seen this type of damage / defect before, and when checking with Ford corporate there were no service bulletins reference this type of problem. This description of events was prompted after reading a news report of Ford super duty trucks exhibiting tail gate openings while vehicle in motion. All service notes and documentation can be obtained through wendle Ford, spokane wa.

This is the fourth time my vehicle has had an srs fault. Repair dealer: bob thomas Ford, 310 w coliseum blvd, fort wayne, in 46805 vehicle purchased from a Ford dealer in west lafayette, indiana in March 2014 with approximately 22k miles and under warranty.

The contact owns a 2012 Ford F-150. The contact stated that the vehicle independently shifted from first gear and failed to change gears appropriately. The contact had to turn off and restart the vehicle in order for it to return to normal. The failure recurred the following day. The dealer (athens Ford, 4260 atlanta hwy, athens, GA 30606, (706) 521-0778) diagnosed that the leaf frame wiring harness in the transmission needed to be replaced. The dealer and the manufacturer made no mention of the service campaign (15n05 electric vacuum pump extended coverage), so the contact was uncertain if it was related. In addition, the manufacturer stated that the vehicle was excluded from a recall campaign. The failure mileage was not available.

While driving the vehicle at normal speeds & operating the air conditioner blower motor on low speed, the driver of the vehicle noticed smoke coming from the below the dash board on the passenger side of the vehicle. 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.

April 26, 2017 the following components malfunctioned simultaneously when returning to truck from shopping: running boards would not deploy or retract; airbag(s) warning light on dash was lit; climate control system, both heat and cooling was out of service; front windows would not respond to controls; seat comfort functions did not work; mirror adjustment and retraction inoperable; back-up system and warnings inoperable; cross traffic system fault; blind spot warning error. Wiring harnesses replaces and picked truck up may 12th 2017. That evening while driving with a trailer, a message appeared concerning the trailer being disconnected. That disappeared and then the following happened: warning messages began to appear on the driver's display screen saying, �your vehicle is not in park�, �check manual�, �downhill assist not operational�. Then the lights went out, the truck lost power (the engine was still running), it shifted into downhill assist, front windows didn't work, passenger seat moved by itself, driver's seat began to go back as if the truck was turned off, then it returned to driving position, the sync display went dead and came back on, the driver's display shut down and came back on. All these things continued to repeat as bells sounded and I limped 5 miles back to my son's house. Same problems exhibited when son took truck to the dealer the following am without trailer. Another harness replaced. Picked up truck and drove without incident about 800 miles. When starting truck, trailer message reoccurred. There was no trailer attached. Two days later after being parked, all the 1st set of failures reoccurred. Running boards, ac-heat, air bags, windows, mirrors, cross traffic system, blind spot warning were all inoperable.

Speed control switch on brake master cylinder caught on fire. Damage limited to switch which was unplugged after failure. Subsequently, brake fluid has leaked out of master cylinder at switch plug resulting in corrosion of brake parts including brake master cylinder and brake booster. Brakes are now malfunctioning resulting spongy pedal and left front caliper grabbing abruptly and locking up causing loss of control of vehicle while braking when driving on any roads in any condition. The leaking fluid has caused corrosion and failure of various parts including mounts for electrical connectors and possibly electrical connectors and wiring.

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.

The contact owns a 2003 Ford F-150. While driving various speeds, the wiring harness burned. The vehicle was taken to the dealer where it was determined that there were un-remedied recalls on the vehicle, and the wiring harness failed and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 145,000.

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.

The contact owns a 2015 Ford F-150. The contact stated that the tailgate slightly detached from the vehicle on its own. The failure damaged the wiring cable on the rear of the vehicle. The dealer diagnosed that the computer wires that were damaged needed to be replaced first in order to properly diagnose the tailgate failure. The vehicle was not repaired. The manufacturer was made aware of the failure, but the contact had not received a response. The approximate failure mileage was 21,000.
