This 2014 pickup was started at about 8:00 AM and the manager went inside the building for a few minutes, (less than 5). A vender that was delivered petroleum product saw that the truck was smoking and on fire in the cab and he told the technicians in the shop who ran out with fire extinguishers to put the fire out. The doors had locked automatically with the keys inside the vehicle. A spare set of keys were acquired shortly and the vehicle was opened with the key. The vehicle was turned off and the hood was popped. a fire extinguisher was deployed while another technician disconnected the battery which then extinguished the fire. The heater motor had melted out of the dash and the dash had started on fire. The dealer was notified and we were told to call Ford and report to our insurance. We are self insured so there is no one to report to. There were no symptoms, problems leading up to this thermal event. The vehicle has 78,000 miles on it and is in great mechanical shape. I have reported it to Ford Motor Company and they gave me a case number [XXX] Pictures INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Fuse 27, a known problem with the 12th generation F150, manufactured from 2009-2014, burned through in my truck melting the fuse block in the process. The fuse block in question is the main fuse block located toward the front of the engine bay near the radiator. This resulted in a no start condition while parked in a parking lot. I was required to purchase Ford’s repair kit for their engineering problem and relocate the fuse to a new spot in the fuse block. If this had happened while driving, I fear my truck could have resulted in an electrical fire with my family inside. Please consider requiring Ford to issue a safety recall for this incredibly dangerous situation.

While driving at highway speed of 55mph, the vehicle went into limp mode. Large gear icon came on the dash, speedometer went out as well as mileage indicator. The vehicle lost almost all power and started to slow rapidly. Pressing all the way down on the gas made the truck go maybe 30mph as a guess. This was a very dangerous situation as there was no where to pull over and cars were coming up behind me quickly. I finally was able to get off an exit ramp and pull over. After restarting the vehicle it moved properly. I scanned the vehicle and received the output speed shaft sensor fault code P0721 and P0722. There is a recall for this problem, but since I proactively brought my truck into Ford in July, all they did was a reprogram instead of fixing the actual cause of this, which is the lead frame in the transmission. Had I waited to bring my truck in for recall until those codes were thrown they would have fixed it. So now I’m stuck with a dangerous vehicle unless I pay for something Ford knew was already a problem.

The contact owns a 2014 Ford F-150. The contact stated while driving 60-70 MPH, the vehicle unexpectedly downshifted to first gear. The contact was able to pull over safely and restart the vehicle. There were no warning lights illuminated. The vehicle was taken to the local dealer for the recall repair under NHTSA Campaign Number: 24V444000 (Power Train). The vehicle was repaired, but after leaving the dealer, the vehicle began to jerk. The speedometer and instrument cluster were blank. The vehicle was taken back to the same local dealer, where it was diagnosed that the failure was due to the molded lead frame. The vehicle was not repaired. The manufacturer was contacted and opened a case, but no assistance was provided. The failure mileage was approximately 165,000.

1. Aug 2024, shortly after transmission recall was performed. I shifted vehicle from Park to Drive, vehicle was on very slight incline and rolled backwards, as if in Neutral. Shifted vehicle back to Park, then to Drive. Same thing happened again, seemed as if vehicle was in Neutral. Turned vehicle off, waited about 2 minutes, restarted and vehicle shifted appropriately. 2. Oct 2024, speedometer, dashboard information system and navigation not working. I had to use my phone's gps to monitor speed and direction. Once I reached my location and it was safe to turn the vehicle off, I did so and waited about 2 minutes, restarted and all information was active and working correctly. This appears to be another electrical/program issue as with the recent issue of downshifting recall. I had experienced the downshifting issue and I had even taken it to a transmission shop but they could find nothing until the recall from Ford was issued July 1, 2024. Thanks in advance for researching above mentioned issues. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I bought this truck 2 and a half years ago and from day one it has been nothing but trouble. I was sold a lemon I have spend God knows how much on this truck and now it sits in the yard with a cracked turbo, electrical issues and transmission problems that I've been told has been a problem along time and I'd have to agree. Within the first 3 months of owning the truck it was in the shop 3 or 4 times. I had all kinds of warranty's added to my loan that I wasn't aware of and I've tried having the issue handled but Ford dealership will not tdo anything about it. I still over over 20,000 dollars on this truck I don't know if you can help but if you can I'd greatly appreciate it. I've had numerous sensors replaced, cv joints replaced, a arms replaced, wheel bearings, catalytic converters, ball joints, brake calipers, brake lines, struts, purge valve, engine mount, fuel pump twice, and I'm sure there's more alot of this was in the first not even year.

This truck has suffered all sorts of issues relating to the lead frame inside of the transmission. This lead frame houses the speed sensor, range sensor ,and temperature sensor. With extensive repairs the issue keeps arising. Ive had 3 new Remanufactured transmissions installed im currently about 6,000 miles into my new transmission with the same issues. Erratic gear changes. Ex. 4th gear to 1st without warning. Loss of 1st,2nd and 6th gears. Becomes stuck in 5th. Just a random array it seems to be with this one almost everytime i cross the 130F degree trans fluid temp the problems start. I have done alot of research into this as i am a technician as well and the only thing i can come up with is bad part production for the sensors and lead frame.

OK, the first problem would be that there was a fuse, apparently, that was engineered too small and eventually would burn up, making a bad connection, which would. all of a sudden shut your engine off. Mel, I was at highway speed, doing 6570 miles an hour, and all of a sudden my engine just cut right out. no power steering, no nothing. just shut right off wouldn't exactly call that a safe situation. Poor engineering second issue would be the fact that you have obvious engineering problems with the fact that they're putting carbon based steel parts or studs in the exhaust manifold that are obviously just going to rot away and it costs thousands to have that problem taken care of. Obviously you don't put that type of steel in an aluminum product because it's not going to last. It's everyone. Everyone knows this. So that's about about it. It's enough to **** **** the Pope. And I think you would have to say that it's a pretty it's a pretty important safety issue. It doesn't matter to me whether or not you know, it was within a warranty. or not. It's an obvious engineering issue or they're just they just don't care. It's the cheapest way to go so they don't give a **** They know it won't happen under warranty. So why worry about it? And that's about it, man. Don't count on me. Everybody in afford again.

While any driving conditions or speeds for no reason at all abs, traction, emergency brake system warning lamps come on. My brakes are good. Took truck to a shop and had brakes inspected and nothing is wrong with the brake system. When turn off vehicle and restart warning lamps turn off. Sometimes the check electronic differential warning lamps comes on with the 3 brake warning lamps.

Throttle body failure causes truck to go into 'limp-home' mode, meaning a significant reduction in acceleration occurs without warning. This is extremely dangerous when driving at highway speeds, turning with oncoming traffic, ect. Many times we must pull over and the truck has to be turned off for several minutes, before we can start it again and continue on our journey. $800+ repair cost is what we were quoted today by the local Ford dealership. Ridiculous! This is a known issue with other 2014 Ford models, but not covered under CSP 13N03. Why is that? Many complaints and two class action lawsuits in California that are pending and it seems like NOBODY cares.

While driving 50mph the transmission downshifted to 2 gear and the rear end locked up and I slid. I was able to shift to neutral and gain control. This has happened twice at that speed and you can feel a jolt like it’s happening at lower speeds. I believe this is an electrical issue in the transmission as the gear indicator on the dash will flicker between “D” and “2”. I have a video of this that can be shared. I have not called Ford yet but there does appear to be a recall on the 2013 F150 models where there is an issue with the lead frame which sounds very similar to what I’m experiencing. My 2014 has the same transmission 6R80 that’s used in that truck as well. There was no warning when this happens.

2014 F-150 has issues with shifting while driving and losing voltage to the transmission lead frame. Safety issue for driving and changing to incorrect gears. When stationary in park, the truck will not start due to loss of voltage and parking sensor issues. Odometer display shows wrench icon shows while driving. Error codes P0706 and P0707 codes show up while driving. Ford dealership has done diagnostics and has determined the problem is the Transmission Molded Lead Frame Electrical Failure. They have reported that this is a common issue.

Driving on the freeway, speedometer starts randomly sensing different speeds like the output speed sensor is not reading correctly. Transmission then downshifts to the speed that the OSS is reading and downshifts to 1st gear while im driving on the freeway going 65mph. It was so abrupt that it locked the differential and chirped the tires, again all while going freeway speeds in traffic! Could have gotten rear ended or caused an accident. I will be taking to Ford to see what they say but i shouldnt have to pay a dime for manufacturing defect and safety issue.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2014 Ford F-150 Supercab Diesel verdict →
