   This vehicle was purchased new. It currently has about 56000 miles. Over time there have been numerous incidents where the battery was suddenly dead. The dealer repeatedly replaced the battery with out addressing the cause. This was done under warranty until recently when there was a charge of $1138. This supposedly resulted in the electronics being reset to factory settings. On a subsequent trip of about 2000 miles , there were numerous incidents (at least 8-10) where the Google Maps program, installed by the dealership, malfunctioned. My question is, what other electronic issues were installed with the factory settings. This has been reported to the dealer, with no response. On August 31, 2026, a request was made to the dealer for copies of service records for this vehicle so that this problem and lack of correction could be challenged. There has been no response, other than their saying “they will make it right “. They are apparently unable to provide service records.

   On September 10, 2026 about 9:10 am, I experienced an engine stall as I was approaching an intersection. I was slowing down and entering a left turn lane. Vehicle bucked like a horse and stalled. No warning lights or codes. It costed to a stop at which time I attempted a re start. The motor turned over for about 10 seconds and then started up. It seemed like there was a loss of fuel. This incident reminded me of a recall letter a got in the mail last year. After research I saw recall #25V455 with no fix yet. Called my local dealer and they said there is no codes so they would probably have to charge me a diagnostics fee of $250.00 and nothing they can do about the recall. Made an appointment and then I cancelled it. What is a person supposed to do? Drive until something bad happens? Take chances and pray for the best?

   Should be able to simply repair my daytime running lamps at a reasonable cost. One of them is now dim, causing lower visibility for other drivers. Ford's cost for me to repair was quoted today at over $2,100. Simply put, unreasonable! This is an issue that has effected several vehicles.

   Daytime Running Light in the headlight assembly overheated and stopped working. Thousands of 2021-2023 F150 owners have had the same issue. This is clearly a mass scale manufacturer known defect and Ford already tried sending an update to lower the LED brightness but the issue still happens.

   ON YOUR VEHICLE, THE WHEEL END HUB BOLT IN THE REAR AXLE MAY BECOME LOOSE OR BREAK. CONTINUED DRIVING WITH A BROKEN BOLT MAY LEAD TO WEAR WITHIN THE AXLE AND DAMAGE THE AXLE HUB SPLINES. I’ve been contacting ford dealerships in my area trying to get this safety recall replaced over the last year every two or three months. I get the same excuse the part is on back order, we have 70,000 on back order others have said 35,000. Yet there is no timetable for when the part will be available. In the meantime I have to drive a vehicle that has had the top of the bolt connecting the tire to the axel snapped off. Ford has completely failed in remedying this issue since the recall and by their numbers making it so 70,000 people possibly have a broken vehicle that they are not repairing or replacing like the safety recall states.

    Fuel pump failed while driving causing vehicle to be disabled in a roadway blocking traffic. The vehicle was then incapable of shifting to neutral so that it could be moved out of the roadway. A Ford dealer confirmed the faulty fuel pump and replaced the part. Ford appears to know this is a safety issue as per recall campaign 25S75/25V455 but they have refused to pay for the replacement fuel pump.

    My husband was driving on the highway with my two daughters in the car when the vehicle stopped driving and he was barely able to pull off the road. It appears to be a defective low-pressure fuel pump. This is an active recall for this model and year, however Ford says that our specific VIN was not involved in the recall. My family could have been killed in this incident!

    Trailer brake controller installed in truck by manufacturer. We wanted to tow our travel trailer and was doing the setup process to test before we left for a trip. We were unable to set the gain for the trailer brake controller. Trailer was connected to truck and plugged in, but unable to change gain or feel brakes when we took a drive around the neighborhood. If we had not taken the steps to test prior to heading out on our trip could have been a serious result. Contacted our local Ford dealer and made an appointment for July 8, 2026. Was told the trailer brake controller connected in the back was not connected. They said this could have happened during manufacturering or just fell out while driving. Still either way could result in serious issues. Not sure if my truck was the only one or are there others on the roads with an issue. If an invoice was provided by the dealership, I have misplaced. They wanted to charge me almost a $100 for them to find it was not connected. The split the cost with me.

    I am reporting a severe safety defect where Ford Motor Company's sequential safety recall software updates are actively corrupting powertrain modules and inducing physical mechanical failures while the vehicle is in operation.Following the completion of the 24S55 Engine Intake Valve Recall (which reflashed the PCM and wiped the transmission's adaptive learning tables), my 2021 Ford F-150 developed an immediate operational shudder. Shortly after, a forced Over-the-Air (OTA) update for the 26C10 Trailer Brake Module triggered a secondary network reset via the CAN-bus. The intersection of these two software-driven actions caused an operational fault that physically broke the torque converter clutch.A compromised torque converter clutch can cause sudden vehicle stalling, unpredictable acceleration lags, and catastrophic powertrain locking while driving at highway speeds, creating an imminent crash hazard. The local Ford dealership service department confirmed the hardware failure and noted that pushing automated software updates over unstable tables leaves the entire transmission highly vulnerable to total systemic failure.Ford is currently refusing to open an escalation file or address this issue. Because Ford's official remedy for safety recalls 24S55 and 26C10 directly introduces a secondary, severe safety risk to the vehicle's powertrain integrity, I request that NHTSA investigate the technical compatibility and safety of these sequential software updates.

    I’m concerned about the 1080R transmission CDF drum issues that ford had on these year models.Mine is downshifting hard at times not every gear but more between 5-8 gears, or especially coming to a stop light it will down shift hard from 3rd to 1st. Shifting up is not as bad as the downshifting but it still does shift harder than normal.Just doing research on others that had the bad parts in their CDF drum issues seem like mine is having same issues.

    When I begin the accelerate from a stopped position I apply the accelerator to begin driving and after a couple seconds after entering the roadway, the vehicle looses power and appears to stall, after a couple more seconds or less the vehicle revs and accelerates very quickly in a jerking fashion and resumes moving forward. Sometimes the vehicle will do this several times in a short distance. This loss of power and erratic motion have happened several times when I have entered into traffic form a stopped position and while driving. I took the vehicle to the dealership where I have it regularly serviced and described the problem. After they investigated the issue I described they were able to re-create the issue and told me that the transmission needed repair. I was able to look up similar complaints and have identified that this is a pervasive issue with the 10R80 transmission in this model year, there is a Ford TSB 26-2226 that identifies the symptoms that I experienced and pointed to a defective part in the Transmission that is the likely cause of the erratic behavior of the transmission and power train. Loosing power and stalling unexpectantly while entering an intersection or in traffic could cause a collision and injuring persons or damaging property. The Service Department where I have the vehicle serviced was very aware of the issue with the Transmission and Ford has issued multiple Technical Service Bulletins to include TSB 26-2046 and TSB-26-2226. This may also be related to Ford Special Field Action 25-L02 regarding the Transmission Control Module and/ or the Safety Recall Notice Ford Number 26S48,/ NHTSA 26V402.

    We broke down because the fuel pump broke, which has a recall out there. We had stopped at Buc-ee’s for a break and when we got back to the truck, it wouldn’t start back up. We got it fixed at Banner Ford and were forced to pay $1822.50 for a fix that a known recall is out for that they claim there’s no remedy for. But, then you’re telling me you can fix it for $1800. It makes no sense that we have to pay for something that there’s a recall for. We are just trying to get our money back.
