2014 Ford F-150 engine problems

ENGINE

I was driving on the highway at about 60-70 mph and my truck shifted into first gear with my tires basically locking up and slid along the highway. I brought my truck into a ford dealership and they told me they couldn’t get it to replicate the incident so they turned me away. I personally replaced my battery terminals and it hasn’t done it again. Now I will be driving and randomly my truck will rev bomb and my gauge cluster will shut off and it shows up with an orange wrench symbol but when I turn the car off it resets. The research I’ve done it can come from a speed sensor or the lead frame. I know 2014 fords have a recall on transmissions but my truck does not have a documented one but there is something funky going on with it.

ENGINE

While driving, transmission will randomly shift gears from a higher gear all the way down to first gear regardless of travel speed. When traveling at highway speeds, this results in a loss of traction on the rear wheels, causing fishtailing and a momentary loss of control. This problem is getting worse, and is the result of a known defect in the transmission speed sensor that has been acknowledged by Ford in previous recalls. The previous recall repair attempt by Ford involved a dealer reset of the computer rather than replacing the defective sensor, which did not fix the problem. The frequency of this sudden downshift is approximately 2-4 times per ten miles driven.

My 2014 Ford F150 truck went into “limp mode” last week. A wrench showed up on my dashboard, my speedometer didn’t function, and it sounded like the transmission was “winding up” if I tried to accelerate. After hitting “ok” to remove the wrench and restarting the truck a couple of times, my check engine light illuminated. I was driving at about 40 MPH when this occurred and it was a scary moment. Luckily I was able to keep my truck under control and drove very slowly back home considering I was less than 4 miles from my home. The truck went into a Ford dealership in 2024 for the “transmission recall” in which the only thing I noticed different was that I couldn’t see the digital shifting of the transmission on the screen anymore and they “killed” my battery. I still had issues every so often with power loss or the transmission shifting down abruptly, but it wouldn’t throw a code. Last week it threw a code. P0720 to be exact, the reason for the transmission recall in the first place. There was no fix done with the recall and it made it so that I had to watch my RPM’s to track my transmission shifting. This is extremely concerning especially since I was having the issues prior to a computer reprogram and it wasn’t addressed. I have also seen that there’s yet another Ford transmission recall that could affect my truck considering it was assembled in June 2014 and fits the transmission 6R80 that needs fixed. Could someone please help? Thank you.

My 2014 f150 xlt Ecoboost 4x,4 was experiencing symptoms directly related to Recall 24S37 / 24V444 (erratic/harsh shifting while on the highway). P0606, P0607 (PCM Processor Faults) P0706, P0707 (Transmission Range Sensor issues) P1702-00 (TRS Circuit Intermittent) P1921-00 (Transmission Range Signal issues) This was following the software update in the last recall. Plus the truck would not start despite a brand new battery. I purchased a new lead frame and was told by Ford to take it to Conklin Automotive in Newton Ks so I had it towed Jan 7th. My truck is still there. They replaced the lead frame but released it to me without a diagnosis, without replacing transmission fluid due to a stripped dipstick they were unable to remove, without trying the many options for removal or refilling it and without checking to see if the lead frame fixed the main issue. I had said from the beginning they needed to check the neutral safety switch and fuses. Finally by end of Jan he checked and found a corroded fuse and the truck started but because of refusal to refill the fluid they didn't check the lead frame. So I have had to rent cars for a month resulting in financial distress and return the truck to a different shop to be fixed. Ford refuses to honor the recall even tho it was extended to my year and model of truck, and refuses to help because Conklin, where they told me to go, is not an authorized dealership. I've attached all the correspondence with them and Ford.

I need to open a safety case. My 2014 Ford F-150 had recall 24S37 performed. Immediately after the recall, the steering locked, the truck stopped itself while still in Drive, and a blue oil pressure warning light appeared. The vehicle is unsafe and cannot be driven out of my driveway. The dealership is refusing responsibility and wants to charge diagnostics. I need this inspected and towed under recall responsibility.”

Coil packs need constant changing in this vehicle. I’ve owned it almost 8 years and sometimes I would have to change the coil packs more than 1 time a year. Obviously I would change the spark plugs also. But there is always a misfire. A lot with 3 and 5.

When driving the vehicle will drop down into a lower gear such as first gear causing the tires to lock up while going into the lower gear, throwing your body in the truck forward causing whiplash and sending my vehicle into other lanes or oncoming traffic. There's a loyd bang when it happens and the engine vibrates so bad when you accelerate it feels like the engine is gonna fall out. They said there's no recall for my vehicle by Vin number but if you put the model in the search registry then 7 recalls come up. Why is my model excluded from this? This is highly dangerous and can kill me or other people on these roads. Ithappens daily. I had just bought it 2 months ago and it happend the same day I bought it and every day since.

Front Engine cover leaking. I have had this issue twice with the same truck two separate engines. I bought my truck used and it was leaking oil. I took it to the dealership and they diagnosed it as the front engine cover leaking. Then before the dealership could get it in to be repaired it started having problems with the timing components. All the problems were supposedly fixed but then about 5 months later the engine failed due to a camshaft failure and I was told this was due to lack of oil. The truck was not even due for an oil change after the dealership had done the repairs. I saved up and bought a brand new engine purchased April 25, 2025. I had the Ford dealership do the first oil change on the new engine and then it started leaking. I took it back and it was determined that it was leaking from the front engine cover, the same as the old engine which I pointed out to the dealership and they informed me that Ford is aware of the problem but there are not any recalls for this. The new engine is under warranty as it isn't even 6 months old and doesn't even have 5000 miles on it.

After receiving a call from Mullinax Ford in Mobile, AL regarding a recall for our 2014 Ford F-150 Raptor (recall related to unexpected downshifting), I brought the vehicle to my workplace on [XXX], where a technician performed the software update (flash) on-site. Before the update, the vehicle was functioning without issue. That same evening while driving home, I experienced extremely hard downshifting, initially in lower gears, and worsening over time. The truck now violently downshifts, primarily into 4th gear, and sounds as if the transmission is slipping. I drove the truck again the next morning and the symptoms persisted. I contacted Zachary, the original representative at the dealership, who said it may be part of the “relearning” process. My husband drove it a week later after returning from a business trip and he confirmed the issue. It has progressively worsened to the point of being undrivable. We returned the truck to Mullinax Ford for evaluation on 7/29/25, and they claimed the failure was unrelated to the update and that the transmission needed to be replaced, at our expense. The truck unpredictably drops gears at high speeds, creating a sudden jerk that could lead to loss of control. This poses a serious safety risk to both the driver and others on the road. The dealership performed the recall software update and later diagnosed the truck with transmission failure, but is denying responsibility. No other third-party inspections have been done at this time. There were no warning lights or issues prior to the update. The issue started immediately after the recall software was flashed and worsened over the next 24–48 hours. The vehicle is currently at the dealership and available for inspection. We believe the issue stems directly from the PCM/TCM update applied under recall conditions. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Truck randomly downshifts/ jerks really hard while driving all speeds. On 4/19 I was driving 65mph and truck felt like slamming brakes on, while speedometer pin bounces around, then a wrench showed up on the dash screen, I pulled over turned truck off sat for a few minutes, turned it back on, everything seemed finer and continued driving home, with no more issues. On 4/27 I was coming home from groccery store going about 30-35mph truck dropped down to first gear and then back to 4th gear. My pregnant wife and daughter were in the car when this happened. I've called local Ford dealership, and they ask me to come in for diagnosis, but I know this is a factory recall issue via 24V-444. I'm not sure if the truck is safe to drive, this randomly happens, but seems to be happening more and more frequently past 2 months or so

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.

Ford Motor Company issued a recall for my truck (the transmission could suddenly shift into neutral), stating that they needed to update the PCM, and my local dealership service center said they could send an employee out to fix it remotely. I had not experienced the shifting into neutral prior to the "fix". Less than a week later, as I was driving around 35mph, the speedometer dropped to 0 and the transmission stuck in 3rd gear. I waited until the next stop sign and turned off the engine and started it again and it went back to normal. The next day the same issue occurred. The speedometer would drop to 0 and the transmission would stick in whichever gear it was last in. This time is was 5th gear on a highway. I had to pull over and restart it 3 times before it resumed normal driving. I went back to the dealership and they said the electronic update wouldn't have caused the OSS to malfunction and that it was a coincidence that the exact issue I was having was the same as the cause and reason for the recall. I went to an independent Transmission mechanic to have the OSS replaced and it has now been over a month and the problem has not returned. I don't know if the cause of the OSS malfunctioning was a coincidence or if it was related to a faulty electronic update (like if the Ford mechanic didn't disconnect the battery or overloaded an electric charge when he updated the PCM). The warning sign of a wrench did appear each time the OSS would drop to 0. The check engine light went on the first time but not after that.

I was instructed to take my truck in for a recall of a sudden downshift issue with the transmissions molded leaf frame. I had told the ford representative that i was experiencing similar symptoms with my vehicle. and some symptoms that were even of even greater risks to me where when coming to a complete stop my vehicle would fail to gain proper speed facing oncoming traffic!! Also i had told the representative that due to those issues i also had the computer re-programmed previously to try to resolve the issue before becoming aware of the recall... i also had purchased an engine and transmission harness from a ford dealer prior to the recall as well, All for which i have not been re-compensated for..after becoming aware of the recall did i understand that the issue lied in the transmissions molded leaf frame which has not been repaired...no actions were taken to remedy my vehicle and i was upset and unsatisfied with the entire process!

Reference Tracking # 11622306. I purchased my used F150 with 52,956 miles on 1/3/2020. Shortly after, I would occasionally notice an unusual gear downshift. Upon receiving Ford Recall 24S37 (NHTSA 24V444000) update for the powertrain control module, the check engine lite (CEL) came on. I called the Ford Recall ph#, and they told me to continue to work with the dealership that performed the update. Several times I returned to the dealership, they would reset it with diagnostics, yet repeatedly the P0299 code would return each time. Prior to the CEL coming on, the CEL was preceded by a stall on acceleration on small hill inclines, and worsened fuel mileage, and typically after towing my trailer. These things didn't occur before the update was installed. (Attachments)

Upon purchase of my vehicle, I occasionally would notice an unusual gear downshift. Then, upon receiving a Ford Recall 24S37 and NHTSA Recall 24V444000, regarding the update to the powertrain control module, I now continue to have a check engine light come on each month with the same error code. I've returned each month since the recall to Ford dealers to have the check engine light looked into further since the update, but each month the check engine light continues to return. Downshift to lower gears continues occasionally. 2 different dealers have seen the codes in the history of the vehicles computer when put through the Ford diagnostics. Invoices provided upon request, if needed.
