The battery will be drained overnight randomly. First time the truck was a year old. Dealer replaced battery. Over a year later, same thing. Replaced battery. I replaced battery four months back and the truck has discharged the battery by the morning. Completely dead battery. Will charge fine and drive fine. No alternator issue. The radio / computer screen will display "battery saver" when the engine is turned off for no reason.

4 Alternator/generator/regulator problem of the 2016 Ford F-150

Failure Date: 12/17/2019

I experienced an electrical failure that was intermittent at first but became worst over time. With this failure I would lose steering and vehicle advance track as well as abs brake function. When electrical power was lost the electrical power steering would stop functioning causing complete lose of steering. This caused me to cross into oncoming traffic, luckily there was no one in the oncoming lane. The dealer found a wire going to the alternator that had worn through causing an over voltage condition. This caused many of the systems, including steering, to shut down. In my research this is not the only occurrence of this issue. My vehicle has 42,000 miles on it. I would guess this will become a much more common issue with time.

5 Alternator/generator/regulator problem of the 2014 Ford F-150

Failure Date: 09/30/2019

Vehicle fire. I started the vehicle up in my driveway and heard a small pop/explosion and smoke came out from under the hood. I immediately shut off the truck, popped the hood and could not identify the source of the issue. I started the truck again and noticed where the fie/smoke was, shut off the truck, and proceeded to rush into the house to grab the kitchen fire extinguisher and put the fire out. Thankfully I was not driving and my house didn't catch fire. I called my mechanic and had the tow truck deliver the vehicle to him and they confirmed that it was the oem alternator that was the cause of the fire. I contacted the dealership wanting to report the issue and the dealership in their words said "not sure what you want us to do?" not are you ok, this is serious let us help, etc. Just a simple passing the buck to a 1800 number to Ford. I filed a case with Ford motor company, but that too was a joke. They didn't care either. I was told they'll file it as negative feedback and since I was so upset, I was directed to create a complaint with NHTSA. I found this very disturbing as Ford appears to not have cared one bit about their manufactured vehicle catching fire or the possibility of someone getting hurt or killed. I hope this complaint finds the right people and prevents a real accident or tragedy from happening. At this time I don't have the repair invoices as the fire did a decent amount of damage even though I did put it out within 60 seconds of it starting. The mechanics are still assessing all the damage done. Since the fire was in the engine bay area on the bottom, there isn't much visible burn damage (and it is currently covered in dry chem from the fire extinguisher). I did file a case with Ford as mentioned and if you need the case number I'd be glad to provide it.

6 Alternator/generator/regulator problem of the 2016 Ford F-150

Failure Date: 09/26/2019

Driving normally on four lane divided state road when warnings about various system failures came up on dash (traction control, braking, charging system). Power steering stopped working first then truck shut down. Got jump started thinking battery or alternator and truck drove normally for a few minutes then same scenario repeated.

7 Alternator/generator/regulator problem of the 2015 Ford F-150

Failure Date: 11/13/2018

I was driving down a city road when the electrical system failed on 11/13. The entire electrical system would go dark for a minute and then come back on for a few seconds, during which I received numerous warning messages. When the system was out, the dashboard display was dead and power steering was offline. I started to receive warning messages about the charging system on 11/6. I brought it to three different places before it failed. On 11/6 advance auto parts told me it was fine. The light went away and later returned. On 11/8 autozone said the battery needed a charge. 11/9 monro said the alternator may need to be replaced. After monro, I made an appointment with Ford. First available was 11/14. The incident occurred after not driving the truck 11/10-11/12. After the incident, I had the truck towed to Ford for service. The dealership finally and reluctantly told me the cause of the failure. Apparently, one or more of the wires connected to the alternator had been severed by rubbing against the housing meant to protect them. The truck was only 3. 5 years old and had fewer than 15,000 miles on it. Ford refused to cover it as it was 6 months out of warranty. The cause of the failure seems to be either a design flaw or a quality control issue. If either of those are the case, a recall may be necessary.

8 Alternator/generator/regulator problem of the 2013 Ford F-150

Failure Date: 10/26/2018

Billy cain Ford sold a truck to me as low mileage with no carfax damage. Salesman tom chacko promised a carfax report at closing. He failed to produce the report upon delivery to me at work. Tom vowed the truck had no damages. Carfax/auto check showed 4 brake failures and 2 alternator failures. Greene Ford verified flood damage 12-11-18. Tom chacko denied their findings 12-12-18, requested written report. Lemon squad documented flood damage 12-26-18. All three reports show consistent flood damage. Jason pirkle warranty/finance manager refused to repair failed emissions stating they were not covered under my extended warranty purchase. The emissions coded 170mi after purchase indicating that code was reset before my purchase. The emissions damage was covered under emissions performance warranty coverage federal mandate. Greene Ford gladly repaired the emissions with no issues. Jason pirkle presented the truck to wells fargo bank, state farm insurance, and Ford motor warranty division as undamaged value. The truck only has salvage value because of the flood damage. Over $5000 in repairs and 34 days in the repair shop. The truck has massive electrical issues from flood damage. I have not driven the truck since 12-11-2018. Major efforts were taken to deceive the buyer of this truck. If billy cain Ford had presented the truck truthfully I would have never purchased the truck. Billy cain Ford did a purchase inspection, maintenance service inspection, and complete detail so they had knowledge of flood damage. A registered mail request for buy back was sent to cody cain 1-17-2019 and he not responded to the request. Billy cain Ford has not made a honest written offer to resolve this issue to date.

9 Alternator/generator/regulator problem of the 2011 Ford F-150

Failure Date: 08/29/2018

The speaker went out in my back left door, so I took the door apart to see what was going on. I tested the speaker and it worked fine, so I started working my way back through the wiring harness. When I touched the harness where it goes from the door to the body (in the door jam) the speaker started working. I removed the harness from the door and pulled back the rubber boot in the door jam. Everything was still wrapped in factory harness wrap, and when I exposed the wires, the speaker wires were severed and most of the wires in the bundle had cracked insulation. There were no signs of being pinched or damaged externally, and I am fairly certain this was just from the bending motion every time the door was opened and closed. I build custom automated machines for a living and we always use flex rated cable for applications like this. So this looks like they used cheap wire with insulation that is not rated for the number of bend cycles a door goes through. Luckily the power wires for the window regulator and door switch had not shorted out despite the copper being exposed. I am very concerned the rest of my doors are suffering the same problem. This could lead to not being able to unlock the door, not being able to roll down the window in an emergency, or even a fire if the power wires shorted out.

10 Alternator/generator/regulator problem of the 2015 Ford F-150

Failure Date: 08/22/2018

While driving there is rattling inside of the steering column that started a few months back. Now my alternator seems to not be working properly and the truck will only crank when I have all extras off (radio, ac, etc. ) I also have to pump the gas for some reason for it to turn over completely. Otherwise it just dies. Never had a problem until last week when it wouldn't turn over at all. My battery is pulling 13. 9 v and I have checked the connections. For a truck to be 3 years old and already need a new alternator appalls me. There is something else going on and the rattling in the steering column is somehow related to me having problems cranking the truck.

11 Alternator/generator/regulator problem of the 2010 Ford F-150

Failure Date: 07/16/2017

Ford f150 4x4 XLT, dash board keeps going out. Shows skidding, and tire sensor faulty, dingging, a/c goes hot, inside lights don't work. Has happened many times, spoke with Ford took it in, they stated they could not duplicate the problem, which we have found out is a lie. They stated we needed a new battery, which we had tested as well as the alternator and nothing wrong there either. We took it to advanced auto to see what they could tell us. A young man said that Ford had put out a inside notice that his buddy showed him of a faulty wiring harness in the dash. He asked if he could show us a short term fix. . . He smacked the dash and all the lights came back on. If we hit a bump it will do it again, or on really hot days, because of the heat. We are waiting on Ford to recall this as it is a serious hazard and maybe start fires. As sometimes you smell electrical, this happens daily when ever we drive the truck, you can have a wreck trying to smack it hard enough to get it to come back on. This happens when you are sitting in the truck , driving, or when you go to start it up. . . You will have no gauges, lights a/c or heat in the winter. Yet the outside lights will work, yet when you push the brakes you hear a loud clicking. This has been happening for approx. 2. 5 yrs +. . . Ford needs to recall and fix this. Everyday we deal with this problems multiple times a day. We brought this truck new and it first did this around 23,000 miles. Now at just over 50,000 miles. There are times that smacking the dash does notwork and we have to wait for it to come on, those time you have to run with traffic or if others are passing you need to speed up. Very dangerous.

14 Alternator/generator/regulator problem of the 2004 Ford F-150

Failure Date: 08/09/2015

My husband was driving home this past Sunday and was starting to turn into the drive when the left passenger window fell down into the door. He had not put it down or up - it just fell down. This is now the 4th window we have replaced in this truck. The other three have been replaced, to the tune of $350. 00 each. When I brought this to the attention of the service manager at the local Ford dealership, he said there was nothing that he could do - the window regulators just break. I contacted the Ford 800 number and was told the same thing - nothing to be done - just a broken part - even though it happens a lot. He said there was no recall on it so there was no help they could give. So, I guess I'll be paying another $350. 00 and pray they don't start dropping again since Ford won't admit they have a problem.

15 Alternator/generator/regulator problem of the 2011 Ford F-150

Failure Date: 03/28/2015

Started the truck in the morning (temperature was 45) and the battery light came on. Took it and had it check and had the battery replaced. After the battery was in, they ran a test and said the alternator was charging too much and the light will come on again. Sure enough after a few seconds, the battery light came back on. Took it to the dealer (apple Ford in red lion, PA) I purchased it from and they said the alternator is bad and charging too much. There stated that there are no after market alternators for this make and year. So after paying $1055. 00 for a Ford brand alternator, the truck was fixed. That is way too much money for an alternator. It is an outrage!! I checked around and I cannot believe that the price of this part is actually this expensive. I asked if they have heard about this problem, and the answer was no. I have been a Ford owner most of my life, but this may change my opinion on Ford trucks for my next purchase.

17 Alternator/generator/regulator problem of the 2011 Ford F-150

Failure Date: 12/20/2013

On the night of Dec 20, 2013, I was travelling south on i81 north of syracuse NY. Road conditions were not very good. A block of ice fell off a truck ahead of me, evasive action was not possible due to ice and traffic volume. The ice struck the alternator which is cleverly positioned about 10" off the ground on the lower left front of the vehicle. The vehicle began to lose electrical power system by system. I cant recall the exact sequence, as it was all happening pretty fast. Eventually, the electric power steering system lost power. When this happens on this vehicle, you lose all steering capability. Its not like its just manual steering, there is no steering other than the ability to slightly alter course by pulling extremely hard on the wheel. The vehicle had no lights, the shoulders were unplowed, stopping wasnt a good idea. As good fortune would have it, the cicero NY exit presented itself at that moment. I was able to pull extremely hard on the wheel and was able to steer the slight curve. At the bottom, I discovered I had no breaks. I shot across the usually busy NY 31 and into a kwikstop, where I stomped on the emergency brake and came to a stop. We shortly discovered a fire underneath the engine and were able to extinguish it with snow. I cannot believe a steering system like this is permitted. Had I known it had this system and its limitations, id never have bought the car. If my son and I had been killed that night, it would have all been chalked up to road conditions. In furious about this system. It needs to be recalled. . . . . Now.

Failure Date: 08/27/2013

We were travelling down the interstate when the red battery light came on. Shortly thereafter loss of power steering, loss of stability control (per dash indicator), and loss of power brakes. I have had the alternator replaced 2 separate times since for a total of three (3) alternators as well as one new battery. Now truck is in shop again for same malfunction. 2011 Ford f150 lariat. Crew cab. V-6 engine. Only 54000 miles and I am anticipating my fourth (4th) alternator. I use the truck in non-mountainous terrain, mostly highway for errands, and rarely tow.

20 Alternator/generator/regulator problem of the 2004 Ford F-150

Failure Date: 08/14/2013

On my 2004 Ford f150 XLT lariat supercab, the passenger rear window regulator has now failed. The driver's one went first (within three years of ownership), then the front passenger one (a few months later) then the rear passenger one ( about a year after the first) and now this. All four regulators have had to be replaced from the original factory installed ones. This latest one occurred while the truck sat parked in the driveway unoccupied; all the others happened on the roadway while the vehicle was in motion.

21 Alternator/generator/regulator problem of the 2005 Ford F-150

Failure Date: 05/11/2013

Rear passenger window regulator stopped working and window fell into door. Had my daughter done this while driving she would have been scared by the loud popping noise and potentially crashed into object injuring herself and or others. This is a common problem and Ford needs to recall the trucks with the plastic parts and falty mechanism. Search the web and there are hundreds of vehicles with the same issue . Years 2004-2006. Ford needs to recall!!.

23 Alternator/generator/regulator problem of the 2007 Ford F-150

Failure Date: 12/29/2012

First why was" this vehicle included in the recall of bad throttle body I had the same problem as people are having with the Ford escape. I reported this back in 2012 when it was brought to the attentioni of the NHTSA I did not receive a response then but there are the same problems with the F-150 I had to replace mine @ a cost of over $600. 00 and also damaged my alternator I was driving in traffic when it went in limp home mode showing a wrench symbol with lost of power and acceleration, I almost was hit by several vehicles as there was knowwhere to pull over time. This is the same throttle body that comes on the Ford escape and it should be included with that group of recalls.

26 Alternator/generator/regulator problem of the 2004 Ford F-150

Failure Date: 06/25/2012

In late-June 2012 a loud clunk/thud/pop/small explosion occurred in the passenger-side door of my 2004 Ford F-150 regular cab truck, while the vehicle was stopped and idling, and the window dropped into the door frame. When I returned home I removed the door panel and discovered that a small piece of molded plastic, 1 1/8" x 1 7/8" (probable cost to Ford about 39 cents) on the window regulator had disintegrated/failed, allowing the regulator cable to release the window. I have found a replacement window regulator on the internet for $70 (Ford charges $175 for the part) and will repair the defective item myself. I notified Ford of the failure of a less-than-quality plastic piece on the regulator and asked for reimbursement. Ford responded: "there are no factory warranties or programs in effect on your vehicle that would provide financial assistance for your current vehicle concern. " however, they did add: "recommend that you keep your repair receipts in case Ford initiates a recall or customer satisfaction program in the future based on customer feedback or further engineering review of similar complaints. " I see from the large number of complaints on this website by Ford truck owners that I am but one of hundreds who have been affected, and obviously, there will be hundreds more; the odds are very high that the majority of the plastic pieces on Ford truck window regulators will fail sooner or later, and I seriously doubt that the 2004 Ford F-150 truck is the only model year that contains plastic parts in the window regulators. $70 to replace a failed piece of plastic that initially probably cost Ford about 39 cents to produce is a sad commentary on quality.

27 Alternator/generator/regulator problem of the 2004 Ford F-150

Failure Date: 10/27/2011

I leave my windows up on the truck. It is cold (winter time) truck was in the garage. I went to the garage and the window on the passenger side was down. I cranked the truck, pushed the button and the window would not come up. I took the truck to the dealer they said the front door window regulator had to be replaced. This cost $344. 66 to replace the regulator. Since the first replacement, the two back windows have done the same thing. I assume if my truck is having this problem others are also. This appears to be a defect and the company should pay for the repairs.

28 Alternator/generator/regulator problem of the 2004 Ford F-150

Failure Date: 09/04/2011

Failure of second window regulator in two years. Driving down the road this time and nearly swerved off the roadway after I thought that the passenger side rear window had been shot out. Turns out it was the regulator failing. Ford needs to recall this part as a safety hazzard before somebody is hurt in a crash caused by the failure of the regulators. Ford knows they have a problem but apparently will not recall or offer a fix.

29 Alternator/generator/regulator problem of the 1998 Ford F-150

Failure Date: 09/01/2011

1998 Ford F-150. Consumer writes in regards to recall notice and problem with charging system the consumer stated after having the fuel straps replaced at the dealer under the recall, a few days later, he began to smell gas. When he looked under the vehicle, he discovered the fuel tank was leaking gas around the rear fuel tank strap, that was just replaced days before. The consumer returned to the dealer and explained to them, the fuel tank was not leaking when he first brought the truck to them. The dealer stated they were not responsible.

30 Alternator/generator/regulator problem of the 2004 Ford F-150

Failure Date: 07/28/2011

While driving in up state NY, going about 30-35 mph, my rear passenger window started to open for no reason. By the time I was able to pull over the window was completely open and fell down into the door. I was unable to close the window and the Ford dealership I brought the car to look at to try and fix it told me the regulator was broken and needed to be replaced. The dealership was able to get the window closed and taped it shut. I was 300 miles from home and I had to get home to try and get the window fixed. This is the second time this has happened to me. About 2 years ago the same thing happened to the drivers window and I had to get the regulator replaced Ford needs to own up to it's default and announce a recall on all it's window regulators.

31 Alternator/generator/regulator problem of the 2004 Ford F-150

Failure Date: 05/02/2011

All 4 windows regulators broke within a span of 4 months. Window regulators have a steel cable which adheres to a plastic pulley--who designed this poor compatibility? common sense will tell you that this is not condusive to wear and tear for electric windows. Vehicle is in excellent shape accept for this problem which as a consumer is unacceptable due to inferior products used. Aluminum or another type of metal should have been used for the pulley--definetly not plastic. Reported to Ford--can't and won't do anything about this but tell me to take to Ford dealer for repairs and pay an outrageous amt for the labor and regulator. I spoke with a local Ford service manager and he revealed to me that Ford knows this is a problem with several of their vehicles and also the lincolns but because of the cost incurred by issuing a recall that they chose to "wash it under the rug". This is an unacceptable excuse as far as I am concerned. 4 window regulators in a 4 month span to break--something needs to be addressed and brought to Ford's management and design departments.

Failure Date: 03/24/2011

On 25 March 2011, I encountered a loud pop in the door on the driver-side of my 2004 Ford F-150 regular cab truck, and the window disappeared into the door frame. I removed the door panel and discovered that the cable mechanism within the window regulator had failed. Without further delay I turned the truck into my Ford dealer to have the window regulator repaired, and received a repair bill of $301. 86 (the regulator alone cost $159. 36); the Ford advisor stated that they had the part in stock since the window regulator failure was a common occurrence. I did not inspect the regulator to determine why the cable mechanism had failed. . Read more...
