Truck has just started misfiring out of the blue, have had Ford dealerships look at it, have changed all 6 spark plugs and one ignition coil. The recall NHTSA 2025-366 may be the reason, it states there still is no remedy for this, recall was issued 1 year ago, July 2025. I need this remedy.

NHTSA ODI 11749262

Recall has been issued on my fuel pump for one year now and there is still no remedy. I do not feel safe traveling far from home knowing this is still an issue.

Good Morning :) This is my second complaint (1st #XXX) as my truck completely shut down as I was leaving the shop around 4:30pm. As I accelerated it shut down in the middle of the street blocking traffic. I was able to start it again, however it shut down a second time as soon I accelerated. NOTE: On XXX I did take my truck into Ford for this issue, however nothing could be done as there was no solution yet. (Mileage 32899) Thank You, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I recently purchased a 2021 f-150 with 48,000 miles on it. Just over 60,000 miles I was noticing some bad shifting occurring with my 10R80 transmission. It progressively got worse by harsh shifting, terrible gear hunting, then finally after driving in manual for a couple days: I was in the middle lane of state road 41 approaching sun lake road, the light turned green and my truck went nowhere. I immediately put my hazards on as cars were trying to get around me and I tried to shift into gear. I managed to find 4th after at least a minute (it skipped 1-3) and I limped to the side of the road where my dad later came with his trailer to pick it up. This is a known issue that ford acknowledges with this particular year for the 10r80 (the CDF drum being the component that fails) yet they have done nothing to address it, even though they DID FIX IT it in the 22+ models. My truck is now at a shop with 60,646.1 miles where they are installing a new transmission for over $5,000 (awaiting for them to finish and I’ll provide the receipt / proof of purchase). Also, they couldn’t even put it in neutral to roll it off the trailer even after disconnecting the computer and manually shifting it from underneath the truck. I’m contacting NHTSA in hopes you can make some noise and file a complaint with Ford, they told me they won’t do anything since I’m out of warranty and there are no recalls for the transmission. It’s ridiculous that I’m dealing with this on just a 60k mile truck that’s a few hundred miles out of warranty and they know this is an issue.

Transmission began shifting hard through each gear. Especially on deceleration. Causes lunging. Early signs were at about 90K miles. Undrivable at 130K. Took to dealership and the said it needs a new transmission. Just under $9k. Their words were, "This is a known design failure". A drum bushing can slide out of position.

My transmission has started to shift hard. While driving at speeds 30-50, the transmission will lag and cause a "jump".

The truck’s fuel system can cut out under acceleration. This is very dangerous. Various times it has nearly stalled out under acceleration while trying to merge. The worst time was driving up a bridge, the truck began to hesitate nearly causing a crash. Every time it signals cylinder misfire, but that whole system has been replaced. Very dangerous, very disappointing.

The passenger side running light in the headlight has gone out. Not the entire part just the vertical section of the running light

The passenger side light has the outer-most vertical LED segment out (not lit up). This appears to be common on this model truck after researching.

Component/system affected: Power train / automatic transmission. Description of safety issue: The transmission has recurring harsh and erratic shifting, most noticeable on the first drive of the day. Symptoms include slipping/flaring, delayed or failed upshifts, sudden harsh gear engagement, unexpected large gear changes, loss of power, and occasional operation as if stuck in 4th gear/limp mode. The issue has become severe enough that I have had to manually intervene and pull over. Specific safety incident: On or about June 24th, I was leaving my apartment complex and turning left onto a busy main street. As I approached and entered the turn, the truck was in 1st gear and I was pressing the accelerator, but the transmission appeared to struggle or delay shifting into the next gear. The vehicle did not respond normally, so I continued applying throttle to complete the turn. When the transmission finally shifted, it engaged extremely harshly and caused the truck to lurch forward unexpectedly into the intersection. I had to slam on the brakes to narrowly avoid colliding with another vehicle. This created a serious crash risk because the vehicle first had delayed/lost propulsion and then suddenly surged forward during a left turn across traffic. Safety risk: This defect can cause unexpected loss of motive power, delayed acceleration, harsh engagement, and sudden vehicle lurching while driving. This is especially dangerous when merging, turning across traffic, entering intersections, passing, or driving at highway speed. The problem occurs without a clear warning light or check-engine light, so the driver may not have advance warning before the transmission behaves unpredictably. I am reporting this because the 10R80 transmission behavior caused a near crash due to delayed acceleration followed by sudden harsh engagement/lurching into traffic, and because the failure appears consistent with a known valve body/CDF drum issue affecting Ford 10-speed transmissions.

My complaint is for an issue that currently has a manufacturer recall as well as a NHTSA recall since Dec. 22, 2023. Manufacturer Recall Number - 23S65 NHTSA Recall Number - 23V896 My right rear axle bolt broke off 2 years ago and I took it to the dealer for repair. At that time they took pictures and the vehicle information to start a claim. They told me they needed to order the parts and would contact me when they received them. As of the date of this complaint the dealer tells me they still do not have parts to resolve this recall. I filed a complaint with the manufacturer and they told me parts should be available by the 3rd quarter of this year (2026) If, that were to happen ? It will be 3 years from the time I was notified of the recall to finally resolving the issue. This is unacceptable for a safety issue to take that long to be resolved and the only excuse is that there are no parts available. I use my vehicle daily for work/income and also for personal use towing a heavy trailer. I cannot believe that a potential accident causing injury or death can possibly occur from a known safety issue to continue because the manufacturer can't get parts. Please look into this matter before someone gets seriously injured or killed. I have been very patient but anyone put in this situation would be very frustrated. Please help me to get my vehicle repaired.

My check engine light has been on for a few months, I called Sioux Falls Ford to ask about it and they told me it's a minimum $200 out of pocket to even look at it. I asked what would happen if the check engine alert had to do with the active recall that is almost a year old that Ford has made no progress to fix, and they said I could file for reimbursement if they deemed the engine warning had to do with the recall. I took my truck to another garage and they found that the check engine light was indeed caused by the fuel pump running at 52psi - the recommended is 51-85psi for my truck. They said the new part would be in the following week to fix it for $1200. When I relayed all of this information to Ford National they told me they weren't able to help me and they were still investigating. They told me that they also weren't responsible for damage to my truck as my powertrain warranty expires next month. They refused to help in any way or offer a timeline of when I could expect a fix. Ford has left me stuck with no options to prevent a potential crash if this faulty piece makes my truck stall on a highway - I can either pay $1200+ for a part from another garage they are legally supposed to fix, or continue to drive a potentially unsafe vehicle based on Ford's negligence. Sioux Falls Ford and Ford National, based on a year timeline with several calls and text chats with both, are refusing to comply with their legal responsibility to remedy this safety recall.

The problem and or issue on my 2021 Ford F150 is the Day Running light on the Upper Passenger side went out and does not work anymore. I reported it to the Dealer. I believe it to be a safety issue if all Day Running lights are not fully operational. This happened with about 66,026 miles on my vehicle.

When using the window wipers, they become inoperable. Stopping in the middle of the window, pausing when moving, or completely stopping and unable to get them to start moving until they begin to move on their own. This has occurred multiple times and at multiple different speeds of operation for the wipers. This was a previous recall issued by Ford that has been completed on the vehicle yet the same result is occurring.

The EPAS (Electric Power Assisted Steering) module experienced an internal sensor failure, causing a sudden and complete loss of power steering assist. The vehicle is available for inspection upon request and the EPAS module has been retained. The loss of power steering occurred without warning while the vehicle was in motion, requiring significantly greater physical force to maintain control of the steering wheel. This creates a serious risk of losing vehicle control, particularly at higher speeds, during lane changes, or in emergency maneuver situations. Because the failure occurs randomly and without any prior indication, there is no opportunity to safely prepare or pull over before it happens, putting both the driver and other motorists at risk. Yes. The issue has been acknowledged by multiple Ford dealerships and independent mechanics, all of whom confirmed this is a known and recurring problem with this vehicle’s EPAS system. Numerous online automotive forums also document other owners experiencing the identical failure, suggesting this is a widespread issue rather than an isolated incident. The vehicle was inspected by an authorized Ford dealership, which confirmed the EPAS module failure and acknowledged familiarity with the issue. No warning lights, dashboard messages, unusual sounds, or handling changes occurred before the failure. The power steering loss happened suddenly and without any prior symptoms, leaving no opportunity to anticipate or react to the malfunction before it occurred.

I haven't had a issue yet, but I'm not comfortable continuing to drive my truck with a known safety recall that Ford has no solution for even though it's been a recall for several months. I live in a area with no Ford dealerships, so it's a little difficult to get warranty work done.

Vertical Daytime Running Lamp is out and from doing multiple hours of research it looks as if it was a quality control issue. The LED board was not secured internally and it caused an LED to touch the tube and burned it. It is very common on 2021-2023 models and the manufacturer changed it for 2024. Please we need to get this as a recall.
