Recently reported ELECTRICAL SYSTEM problems on 2012 Ford F-150

Went to drive pickup and check engine light came on, next low fuel light came on even thought the vehicle has a full tank of fuel. transmission would not shift, gauges are flipping back and forth. tried to shut vehicle off and it would not shut off once i did get it to shut off it would not restart.also all the warning lights on the dash were are going off. vehicle was in motion on the highway.

My 2012 f150 with 82k, miles on it 08/08/2019 got in my vehicle starter vehicle it made a strange noise from engine compartment proceeded to back out of driveway and had no power steering. what scares me is what if i had been on the freeway at 50 miles an hour or better and the power steering went out? also my door lock on driver side would not work paid $400 to have it fixed now the passenger side has failed. my question is what if i could not get out if my trucks power steering went out while driving and crashed i couldn't get out. i feel this is not a coincident,i feel this is factory defective parts! there's too many of the same reported incidents, does someone have to die before we get a fix? my next step is social media and a 20 20 investigation into why no one has made an attempt to save human lives as opposed to bribery and fat bank accounts. i believe it is a power steering modular/factory defect. also i don't know what is making the door locks fail except for factory defective equipment,i'm not a mechanic just a hard working american citizen, made in america used to mean something! i've made copies of this report for future use. for future correspondence; [xxx] to whomever receives this report i hope doesn't put it in the dead file. thank you, i think? information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tr

What driving and a/c cut on and off and had smoke coming from the vent and not long after passenger side dash caught on fire

Tl* the contact owns a 2012 ford f-150. after the vehicle was shut off, the battery failed and the vehicle could not be restarted. the vehicle was taken to blue ridge north georgia ford (7525 e. appalachian highway, blue ridge, ga) to be diagnosed, but the cause of the failure could not be determined. the contact was also informed that the remote control module was damaged due to the battery failure. the manufacturer was notified of the failures. the failure mileage was 39,000.

On at least 6 occasions, truck misfires and shakes violently when under load or attempting to accelerate. pull off road or let off of accelerator and engine resumes normal operation. happened once pulling empty trailer, happened 4 times merging onto interstate. happened multiple times passing / accelerating on interstate. frightening and dangerous when truck shakes violently on interstate. roads were wet or rainy conditions in last 5 incidents. 2012 f150 fx4 with only 87000 miles. no accidents. truck maintained and in excellent condition.

While traveling at 70 mph the vehicle stalled with the engine shutting down in main lanes of an interstate. the stalled engine resulted in the loss of all power assist features including power steering and power brakes. we were able to navigate across several lanes before coming to a complete stop in a traffic lane but not safely off the interstate. after calling for a tow and requested service. it was determined that a fuse powering the electric fuel pump had "burned" out and had to be replaced. should have been a simple solution, upon further investigation it was determined the fuse panel had been damaged and would no longer accept a fuse and has to be modified with the fuse location moved to a new location and upgraded to a more robust fuse and fuse placement slot. ford has been aware of this problem and has only elected to fix those vehicles that exhibit failure and at the cost of the consumer if not within the warranty period. this vehicle has been returned to ford dealers multiple times with no mention of this problem or repair. ford has issued a technical service bulletin (tsb 15-0137) and has created a specific replacement kit, which includes instructions and all necessary parts to perform the relocation (motorcraft # el3z-14293-a). this should be a recall as it impacts the safety of ford's f150 owners, their passengers and those that share the road with them. failure of all power assist functions while traveling at highway speeds is scary and creates a dangerous situation for those in the vehicle and those around it. it also creates an even more dangerous situation if the vehicle was being used to cross a busy intersection, stalled and then stopped in the center of the intersection. included are pictures of the fuse and the fuse block damaged during the failure and honestly, a fire could have easily started as a result of this failure.

Tl* the contact owns a 2012 ford f-150. while driving at an unknown speed and making a left turn, the contact heard a loud noise for about a week. there was an intermittent internal electrical failure and the steering wheel seized. eckenrod ford lincoln (5255 al-157, cullman, al 35058, (800) 944-1389) indicated that the vehicle would need to be diagnosed to determine the cause of the failure. an independent mechanic diagnosed the vehicle and informed the dealer that two sensors and the steering column needed to be replaced. the dealer stated that the failures were a known issue. the vehicle was to be repaired by the independent mechanic. the manufacturer was notified of the failures. the failure mileage was not available. *bf*jb

For over 2 years now an issue with the driver tran module has been causing my truck to go from any gear into first, locking tires up and causing issues while driving at any speed. ** safety recall was made on driver tran module **. however, my truck is now in worse condition without a fix to the issue, but my truck is now shutting the entire computer module down and i have further transmission issues.

My vehicle was serviced for recall 19s07 regarding unexpected downshifting in to first gear while driving. after my vehicle was serviced, my truck began downshifting in to first gear while driving. a new recall 19s19 was issued for improper/insufficient repair of original recall 19s07, however my vehicle's vin is not yet showing up under this new recall, but my vehicle is still downshifting in to first gear while driving

Tl* the contact owns a 2012 ford f-150. while the vehicle was idling at a traffic light, it stalled and failed to restart. the contact stated that the fuel pump fuse was replaced and the vehicle restarted. the vehicle was not diagnosed or repaired. the manufacturer and dealer were not contacted. the approximate failure mileage was 73,000. .*bf the consumer stated had to purchase a rewire kit from ford to prevent the problem. *tr

Tl* the contact owns a 2012 ford f-150. the contact stated that the fuse overheated and prevented the vehicle from starting. the failure occurred intermittently. the vehicle was taken to iron city ford (9924 parkway e, birmingham, al 35215) where they stated that they would replace the wiring and fuses. the manufacturer was made aware of the failure. the vehicle was currently at the dealer awaiting repairs. the failure mileage was 89,854.

Feb 24, 2019 was pulling out of church parking lot when ford truck suddenly died while merging into traffic. luckily i had enough space to maneuveur to the side. i turned vehicle off and tried to restart. ford truck would only crank..(no start) i had truck towed home. after reading on internet i looked at fuel fuse f27 20 amp. sure enough it was burned. i replaced and vehicle started up. i asked dealer about warranty under the federal emission warranty and they said nothing exsist. i have read enough to know this is a dangerous issue that ford knows about and should repair.

While the rear defroster is activated the glass shattered due to what seemed to be a problem with the electrical for the defroster. vehicle was stationary and running at the time of the incident.

This truck is spontaneously shifting down to 1st gear. it is also getting stuck in different gears and not shifting properly, ford supposedly has a customer satisfaction program extending the warranty to 150,000 miles for the lead frame, however i took it to my local ford dealership and they do not want to honor the customer satisfaction program. i called ford corporate and the same thing. not only when this problem happens does the transmission mess up but so does the instrument cluster, to the point where the speedometer doesn't work and the airbag light comes on.

Rear passager door ajar come on when off causing intreral light to stay on .the timer can be turned off and still stay on pass 30 sec longest time stortest 10 sec.

Transmission shifts erratically, jumping from lower to higher gears. while up to speed, immediately shifts to 1st causing redlining of rpms. speedometer jumps erratically. happened initially while accelerating from a stop. caused loss of power and feeling of misfiring, then sudden surge forward. after getting up to approx. 40 mph, transmission shifts to 1st and stays there. could have easily caused a crash if this happened while cruising at highway speeds.

Transmission - output speed sensor is faulty. had a recall, said the transmission module needed reprogramming, however this did not fix issue of downshifting to 1st gear and unable to shift out of. also happens to 3rd and 5th. other 2012's have lead frame assembly replacement which takes care of faulty output speed sensor, my recall of re-programming has all the symptoms of the lead frame recall but is just outside the manufacture date and not included

I bought the truck in april or may. when my truck is stationary and turned off with the keys out of the ignition, my dash lights do not shut off. i didn't notice this the first time because, at night, my lights stay on for about 20-30 seconds and then shut off. the first time i noticed this, i got home for the night, put my truck in park, shut it off, and took out the keys. i used my remote to lock the truck. got in it the next day and it was completely dead. i had to put it on the battery charger for about 30 minutes and finally got it started but i noticed while charging it (with the keys out of the ignition) that my dash lights were still on. its almost like my truck does not know that it is in park and it thinks it is still in gear which keeps my dash lights on. a few days before i started experiencing this issue, my remote starter would not work all of the time. it was very hit or miss. i'm not sure what to do about this.

Big yellow wrench appeared on ip cluster while driving, speedometer dropped to "0", tachometer now won't drop to "0" reads high all the time. took it to the ford dealer, was charged for a "lead frame" replacement; tachometer still doesn't work; now i find out there is/was a recall on the lead frame.

Tl* the contact owns a 2012 ford f-150. while driving approximately 50 mph, the transmission downshifted into first gear without warning. the contact temporarily lost control of the vehicle and it spun out of the right lane into a grassy area. the contact stated that all four tires seized and the vehicle was immediately placed into neutral. the contact was able to stop the vehicle. during the failure, the speedometer and instrument panel became inoperative. the speedometer gauge increased and decreased and the instrument panel lost power completely. the contact was able to restart the vehicle, but the failure recurred. the contact stated that the vehicle downshifted and upshifted randomly. grieco ford of delray beach (3000 south federal highway, delray beach, florida 33483, (561) 278-278-0303) and autonation ford margate (5401 west copans road, margate, florida 33063, (954) 644-4976) were made aware of the failures and stated that there was no recall on the vehicle. in addition, the dealers requested a diagnostic assessment. the vehicle was not repaired. the manufacturer was made aware of the failures. the contact attached a diagnostic code reader to the vehicle and referenced diagnostic trouble code: oss sensor (p0720). the failure mileage was 119,218.

Vehicle has less than 45000 miles. has erratic loss of power while accelerating. evidence of water in the air intake. research is showing that the ecoboost engine is collecting more water in the intercooler than the engine can consume. problems increases in southern humid states. this is problem caused by faulty engineering in the 3.5l ecoboost engine and could cause accidents due to unpredictable loss in power. loss of power is felt while driving on city and highway driving.

Takata recall my truck keeps downshifting and locking up my back wheels on the highway. i just almost had a wreck and this is getting ridiculous.

The vehicle would downshift into 1st gear without warning, has occurred when vehicle was traveling approximately 35 mph. the vehicle would also remain in 1st gear after these incidents and intermittently when leaving from a stop, at an intersection. vehicle has done this several times, in which case the dashboard displayed an illuminated malfunction indicator light and gone into limp mode, with only 5th gear available, while in an intersection. this problem would also cause the odometer to read '-------.--' and the speedometer to read '0 mph', even when the vehicle is in motion, travelling at any speed. vehicle is in otherwise perfect operating conditions. diagnostic trouble code p0720 was displayed during these incidents. the manufacturer has customer satisfaction program 16n02 for 'certain' vehicles, in which the dealers are replace the molded lead frame within the transmission. in the case of my vehicle, this program did not apply to my vehicle, while at the same time, the molded lead frame within the transmission was determined to be the source of the issue and subsequently replaced. with my vehicle not applying for the noted customer satisfaction program, with the same faulty part as noted within the specific customer satisfaction program, it is my opinion that the affected vehicles with deficient molded lead frames is far greater than what was initially thought and therefore, the recall program should be extended to all f-150s and similar vehicles within the specified build dates, as noted within the customer satisfaction program. the molded lead frame failure should be considered a manufacturing defect and causes serious safety concerns for the drivers of those vehicles and to the travelling public.

The fuel pump relay and power fuses both melted which has caused starting issues and engine misfires. there are many reports of the same fuses melting in ages 2010 -2014 of the same ford f-150 trucks. this should be under a ford recall program as it caused trucks to loose power.

Tl* the contact owns a 2012 ford f-150. while driving various speeds, the vehicle downshifted independently. the contact stated that the maintenance and air bag warning indicators illuminated. in addition, the speedometer and odometer ceased to function. ted russell ford lincoln (9925 parkside dr., knoxville, tn) diagnosed that the power train control module needed to be reprogrammed. the contact referenced nhtsa campaign number: 16v248000 (power train). the manufacturer was contacted and informed the contact that the vin was not included in any recalls and advised him to contact nhtsa to get the vin included in a recall campaign. the failure mileage was approximately 84,273.

Tl* the contact owns a 2012 ford f-150. the contact stated that the vehicle failed to start. in addition, while driving various speeds, the vehicle stalled without warning. the vehicle was able to coast to the side of the road. when the contact powered off and restarted the engine, he was able to drive normally. the contact stated that the failure recurred multiple times. the vehicle was taken to crossroad ford of wake forest, inc. (10101 capital blvd, wake forest, nc 27587, (877) 331-8117), but was not diagnosed or repaired. the manufacturer was notified of the failure and filed a case. the approximate failure mileage was 137,983.

Vehicle was stationary. turned defrost on rear power slider window. saw smoke come from the bottom of the passenger side rear window (outside window trim piece bottom). turned the truck off immediately and heard a loud explosion. the rear window on the passenger side shattered

Tl* the contact owns a 2012 ford f-150. while driving various speeds, the vehicle inadvertently downshifted and lunged forward. also, the instrument panel lighting flickered and went completely dark. the contact pulled over and restarted the vehicle. beaman ford (1717 tn-46, dickson, tn 37055, (615) 446-2308) repaired the main cluster, but the failure recurred. the vehicle had not been repaired again. the manufacturer was made aware of the failure. the failure mileage was 88,800.

While traveling at 48 mph on 2 lane county rd i was in 4 wheel high when truck slammed into 1st gear causing truck to loose traction and ended up going into ditch. the truck never stalled out all gauges stopped working and tech light came on. i proceeded to be pulled from ditch. then turned truck off .checked truck over it has body damage nothing visible under truck so i started it gauges where working tech light was off radio stopped working but could be loose connection i proceeded to limp it home at about 20 mph was shifting hard at higher rpm i had it towed to body shop while at hospital.recall came on news i went to dealership they said bring it in they'll reprogram it . i'm wondering about damages caused by defect who will be paying for that? this defect is a danger and i can't believe it took ford 7 years from first report on here to address issue. and they claim only 5 cases of a crash which i have found 7 people who have had accidents because of it 4 of them where single vehicle 3 involved being rear ended because the sudden stop very disappointed in ford. *tr

Vacuum pump runs excessively and is noisy. this is already a known condition to fomoco. they advise my vehicle is not covered under covered u der customer satisfaction extended service bulletin. https://ford.oemdtc.com/1760/15n05-electric-vacuum-pump-extended-coverage-2011-2012-ford-f-150 ford reference # cas-24279039-d5h0k6

Rear window defogger quite working

Tl* the contact owns a 2012 ford f-150. the contact stated that the vehicle downshifted unexpectedly and the speedometer independently ceased to function. in addition, the air bag and maintenance warning indicators illuminated. the vehicle was taken to art hill ford lincoln (901 w lincoln hwy, merrillville, in) on four occasions, but the failure could not be diagnosed. the vehicle was also taken to paul heuring ford (720 n hobart rd, hobart, in) where it was diagnosed that the molded lead frame was defective. the manufacturer was notified and stated that the vin was excluded from nhtsa campaign number: 16v248000 (power train) and customer satisfaction number: 16n02. the contact was also informed that nhtsa was responsible for adding the vin to a recall. the contact was referred to nhtsa. the failure mileage was approximately 74,000.

My f150 started to drop in to 1st gear unexpectedly when driving at at speeds greater than 50mph. at first the check engine light did not come on and mechanic could not find a source now i am getting engine codes p0720 and p0722. when i tried to investigate i found that this has been recalled on some 2012 ford f150 but not mine. this is a serious safety issue and has cause unexpectedly down shifts on national interstates. i urge you to please investigate this thoroughly.

I turned on the rear defrost and my passenger side of the rear window shattered. there was a loud noise when it happened. i was driving when this happened. the dealer and other ford personnel have admitted this is a widespread problem - but no recall.

My 2012 f150 rear drivers side window section suddenly shattered after turning on the rear defrost function. rear defrost went on then i smelled something burning g. the rear drivers side glass section then shattered. there was absolutely no trauma that caused this. the rear defrost will no longer operate since. i contacted ford service and there is no recall at this time. i searched online and found close to 150 similar complaints. when the glass shattered the temperature was near 30 degrees and the vehicle was not in motion.

Right rear window spontaneously shatters with a sound like a rifle shot 10 minutes after rear defrost elements were turned on. nothing struck glass. no evidence of impact. vehicle moving only ten miles an hour in a parking lot.

Started my vehicle on a cold morning turned on the window defrost and rear defrost. came back to it a few minutes later and the back window was smoking and the gasket had caught on fire. it shattered the window and burnt and melted the gasket. this seems to be a big problem with the f150 with rear defrost and power sliding window it either breaks the window or catches fire mine did not even blow the fuse. have seen many cases of this thru f150 forums and ford has not come up with a solution. it is also a very expensive fix . my vehicle was stationary in my driveway had i not caught it in time this would have destroyed my truck and caught my house on fire too

I was driving on the highway. while accelerating the truck died. i had just enough momentum to get to the side of the road. not knowing what happened i got my truck towed home. after researching all nigh, the next morning i pulled fuse #27 low and behold it was melted. i couldn't believe it, i felt very fortunate that it didn't cause an accident. i would like ford to right this common problem because of safety. i couldn't imagine how mad i'd be if my family were in the truck with me

Tl* the contact owns a 2012 ford f-150. while driving 70 mph, the gear automatically shifted into first gear. also, the wrench warning icon illuminated and the vehicle automatically went into limp mode. the contact pulled the vehicle over to the side of the road. when the contact turned off and restarted the vehicle, it performed normally. the vehicle was taken to the dealer (towne ford, 1601 el camino real, redwood city, ca 94063) where it was diagnosed that the software needed to be reprogrammed. the vehicle was repaired, but the failure recurred several other times after the repair. the manufacturer was contacted at 800-392-3673 and stated that the vin was not included in a recall, and the contact would have to pay for the repair. case number: cas-13431428 was provided. the approximate failure mileage was 94,000. *bf updated 8/6/18*jb

Vehicle randomly shifts up and down. it will sometimes shift from 1st to 6th and then the vehicle does not go since it is in high gear. other times, it will shift from 6th to 3rd. this happened while driving 70 mph on expressway, it shifted to 3rd and caused the vehicle to jerk. i researched and others have had similar issues. took to ford and they said it needs a new lead relay which will cost $600.

Tl* 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.

Tl* the contact owns a 2012 ford f-150. the contact took the vehicle to be inspected and was informed that the horn failed. the dealer (wilson ford, 304-363-0500) performed a repair that enabled the horn to function correctly, but the repair specifics were unknown. recently, the horn failed to sound when it was pressed. the contact took the vehicle to back to the dealer, but the cause of the failure could not be determined. the vehicle was not repaired. the manufacturer was not made aware of the failure. the vin was unknown. the approximate failure mileage was 66,000.

When parked with ignition off and no one in the truck drivers side door will not unlock with key or inside on the unlock switch. when i first noticed the problem sometimes you can unlock and lock repeatedly and it would unlock but now it wont do anything. both doors lock fine but when unlocking only the passanger side door unlocks. this is on an extended cab xlt.

The audio system has stopped working in the truck i own. the dash time flashes but none of the dials work. this occurs when it is stationary or in motion.

Tl* the contact owns a 2012 ford f-150. on several occasions, while driving various speeds, the vehicle stalled and lost power. the contact was able to restart the vehicle after 30 to 40 seconds. there were no warning indicators illuminated. the vehicle was taken to a dealer where it was diagnosed that the fuel module wires melted and needed to be replaced. the vehicle was replaced. the manufacturer was notified of the failure, but did not offer assistance. the failure mileage was 125,853. updated 08/24/17*lj *cn

Truck goes into limp mode while driving and displays a wrench on the screen. happened multiple times while driving at full speed and once while pulling out into traffic almost causing an accident. our local ford says they cannot see us for 3 more weeks because they are so busy. a local mechanic tells us it is the throttle body. from what i read this is a common problem. i'm truly scared to drive the vehicle. the vehicle just all the sudden loses all acceleration and stops. the only way to get it moving is to put it in park, turn it off and re-start. when on a highway going 60 miles an hour this is very unsafe!

My transmission intermittently shifts from high gears to low gears and vise versa. this occurs both when accelerating and when in high speeds. it appears to be a lead frame issue according to the dealership in el centro, ca. it is quite dangerous and scary when my child is in the car. i found 16n02 extended warranty and recall #16s19, but they do not cover my vehicle. they should!

Tl* the contact owns a 2012 ford f-150. while the vehicle was parked and activating the rear window defroster, the rear window shattered after several minutes. the vehicle was taken to an independent mechanic, but was not diagnosed or repaired. the approximate failure mileage was 80,000.

In warm weather the truck suddenly shakes and downshifts to first gear no matter what speed you are going. the speedometer stops working, a wrench is displayed on dash sometimes. the speed after doing this does not exceed 20-25 mph. if we can safely get to the shoulder of the road and turn truck off and restart it everything resets. this happens atleast once daily, sometimes more than once daily. it always happens when truck is in motion. it does not matter what speed as it has happens at different speeds and on one occasion when i was in the process of stopping for a red light. the last occurrence happened today, but it has been happening for several months. when it is cold outside it does happen less, maybe once weekly instead of multiple times daily when the weather is warm outside.

Dealer identified fuse #27 melted causing stalling and potential to overheat circuit causing an electrical fire. not covered under ford certified pre owned warranty for powertrain etc. vehicle stalled in traffic and failed to restart until after third attempt..
