Failure Date: 07/22/2025

My truck completely shut down while leaving the shop and I was only going about 6-10mph. The dash alert stated "fuel accessory" or something in orange, sorry, I panicked a little:) I took it to bradley Ford the next day and they couldn't fix it as they didn't know the issue. This happened a second time, but didn't shut off completely, it just felt like I was running out gas (full tank). I do live in lake havasu city, az and it's hot here so I don't let my truck go below 1/2 tank hoping this will help avoid a major accident. Thank you! julie burns 928-208-2867.

I am submitting a formal safety complaint regarding my 2021 Ford F-150 lariat 5. 0l v8, which is included in recall 25v455 (Ford campaign 25s75) involving low-pressure fuel pump failure that may cause engine stall while driving. Ford announced this recall in 2025, acknowledging a potential safety-related defect that can result in loss of propulsion. However, as of April 2026, no repair remedy has been made available for my vehicle. This extended delay leaves owners operating vehicles with a known safety defect and no practical means to correct it. An unexpected engine stall while driving creates a serious hazard, particularly in highway traffic, intersections, merging conditions, or when towing. Owners should not be left indefinitely without a repair after a manufacturer has identified a defect significant enough to warrant a federal recall. I respectfully request that NHTSA review the prolonged delay in remedy availability for recall 25v455 and require timely corrective action, clear owner communication, and appropriate interim measures where necessary. Please also review whether affected owners are receiving adequate notice regarding expected repair timing and risk mitigation steps while awaiting a permanent fix.

38 Other Fuel System problem

Failure Date: 07/10/2025

I was turning left from a side street onto a divided highway and stopped in the middle to wait for an opening in traffic. When one came I hit the gas and nothing happened. Pressed it again, to the floor and nothing happened. I then put the truck into reverse to back out of the way of traffic because the truck rolled forward a bit when I attempted to accelerate. I then waited for a very large opening and attempted to accelerate again. Pushed the pedal and again nothing. I then pressed it to the floor and held it there. The truck very slowly began to accelerate and then after about 20 seconds accelerated like normal. The truck seemed normal the rest of the way home.

41 Other Fuel System problem

Failure Date: 07/01/2025

This recall has been going on for over a year. I don't know how long these usually take, but this recall - manufacturer recall number25s75 NHTSA recall number25v455 recall statusrecall incomplete, remedy not yet available my truck runs rough at times which I believe is a direct result from the fuel pump on this recall, and it doesn't give me much confidence on my daily driver truck, especially going on long trips. I don't know if this message carries any weight in the timeline on this recall, but I would really like this fixed soon so I don't have a stall incident with my family in the vehicle.

Failure Date: 06/15/2025

Was wanting to know if or when this recall will have a fix it has been 14 months when the recall was issued. I bought my auto thinking it would be drivable for long trips and Ford is still selling new auto. Not right for the people with the recall. Thanks.

43 Other Fuel System problem

Failure Date: 04/07/2025

Due to a defective door (cheap plastic pin), the check engine light comes on with associated warnings on the fuel door not being shut. It is shut but not locked due to the defective pin (I believe plastic) that interacts with the warning light and warning message.

44 Other Fuel System problem

Failure Date: 02/26/2025

Vehicle has completely unresponsive gas pedal for 3-5 seconds. Gas pedal is completely dead. This occurs randomly but mostly in a stop and start accelerating situation. Once the 3-5 seconds passes gas pedal responds normally. No codes generated during incident.

Ford motor company has issued a safety recall, identified by letter nef-107dg and recall number 24v-957, due to the potential failure of the cp4 fuel pump in certain vehicle models. The recall affects the following makes, models, and model years: Ford/f-250 sd (2020-2022), Ford/f-350 sd (2020-2022), Ford/f-450 sd (2020-2022), Ford/f-550 sd (2020-2022), Ford/f-600 sd (2020-2022), Ford/f-650 (2021-2022), and Ford/f-750 (2021-2022). This action addresses concerns that the cp4 pump may fail prematurely, potentially leading to engine stalling and increasing the risk of a crash. Notably, my 2021 Ford F-150 XLT with a 3. 0l diesel engine is equipped with the same cp4 fuel pump as the models listed above. As such, it should logically be included in this recall to ensure consistent safety measures and address the risks associated with this known defect.

46 Other Fuel System problem

Failure Date: 11/07/2024

After a right turn in a residential street, I pressed the accelerator to progress on the roadway. The truck did not accelerate, so I looked at the tachometer and observed it above 0 and below 1,000 rpm. The engine was running, but unresponsive despite pumping the accelerator. While rolling at 5 mph I shifted the transmission to neutral and continued pumping the accelerator. There was no response for the next 200'. Finally, the engine became responsive and ran normally. It runs normally now. I cannot reproduce this issue. I called the Ford dealer service on 8 November 24 at noon and they said "watch for the issue". I expressed that in traffic, a suddenly undependable engine is a serious concern. The accelerator/engine was unresponsive for a continued period of time. The gas engine was in control. There was no check light/warning light. The Ford dealer inspected the telemetry of the vehicle remotely and no anamolies were observed. The dealer declined to inspect the vehicle since the issue is not reproducible.

Failure Date: 09/05/2024

I've experienced the loss of power during hard acceleration. Right hand turns from a stop feel like the engine has stalled and rolling right hand turns are becoming increasingly more dangerous. Most recently as I was merging onto a highway. Pedal to the floor, the truck initi9ally accelerated for a couple seconds until it stalled to make the truck not only not accelerate but almost made it feel as if I was breaking. This is very dangerous.

Failure Date: 09/04/2024

Cruising highway speeds, when accelerator is pressed to gain speed, make a pass, ect the transmission downshifts into 3rd gear, engine losses all power for 4-8 seconds while accelerator is held down. I’ve almost been in several accidents due to expecting a vehicle to accelerate and nothing happening and traffic.

49 Other Fuel System problem

Failure Date: 06/30/2024

Despite having been told my truck was fixed at a dealer shop, my truck still displays an absence of forward propulsion when applying the gas pedal and trying to accelerate from slower speeds. This has happened when trying to make a left or right turn when there is oncoming traffic. Sometimes this happens while trying to accelerate on the on-ramp of a highway to get up to normal piste speed limits with traffic very fast behind me. The dealer I took it to said they fixed the issues. Luckily I can apply the manual mode with a button, but this is distracting when trying to look for the button, and the issue comes back in automatic mode.

Obdii reader which connect to vehicle ecm reads perfectly independently, however when connected to a state emissions inspection machine, machine indicates no vehicle information available and results in failures due to ecm not responsive. Ford says it is a known issue but will not replace ecm unless recall is issued.

52 Other Fuel System problem

Failure Date: 07/03/2023

Bought truck brand new. The axle bolt sheered off at 76k miles which is a common problem which Ford has issued a service bulletin for repair. Ford claims my truck is not drivable due to the manufacture defect of the bolt either being cross threaded or overtightened from the factory. Ford is insisting I pay for the mistake even though it's a manufacture defect with a service bulletin for a repair. Ford is refusing to pay for the fix due to miles. Axles, axle shafts and axle bolts should not have to be replaced before the differential fluid does in the axle at 100k miles. They are claiming the extreme premature wear is my fault. The truck is bone stock. Ford case #cas-43720120-d7h6y6. Worst part is Ford dealership telling me claim was denied to only find out Ford approved the claim partially. The Ford dealership was trying to double dip on profits. Dealership is wade Ford. Called up akins Ford in winder and they told me they would cover it.

I have owned my 2021 f150 less than 2 weeks. I purchased the car with 200 mile on it. I was pulling out of a parking lot tonight and heard a clunk. 50 feet later the engine quit and there was a strong fuel smell and something was scraping on the pavement. We got out of the car and there was a big puddle of fuel under the vehicle. Upon further inspection, the front fuel tank bracket was unhooked from the right side and the front of the fuel tank was resting on the pavement. The fuel tube connection at the front of the gas tank was sheared off. We had the truck towed to anderson Ford in rockford, IL.

I am filing this complaint regarding an unresolved safety recall on my 2021 Ford F-150 (VIN: [xxx] ), recall 25s75 / NHTSA 25v455, issued July 2025. As of today, April 10, 2026, no remedy is available and Ford has not provided a firm commitment beyond a verbal statement from a customer service representative. I contacted Ford in writing via certified mail (delivered March 27, 2026) and by email. Ford case number: [xxx]. I received one email response on March 31, 2026 from patrice hargrove, truck concern cxs, stating the remedy would not be available until June 2026, that Ford had not advised me to stop driving, and that Ford would not provide a loaner or rental reimbursement. I responded the same day asking for written confirmation of the June 2026 date and confirmation that my correspondence had been documented in my case file. I followed up again on April 6, 2026. I have received no response to either email. My concern is not only the recall itself but the history of this specific vehicle. In October 2022, this truck stalled in the middle of the street while I was driving with my children in the vehicle. It was towed and serviced, with the cause attributed to alternator failure. The failure mode described in recall 25s75, an engine stall caused by fuel pump failure, is the same experience I have already had with this truck. This vehicle has also undergone a rear axle wiring harness repair in June 2024 and a transmission service under customer satisfaction program 25l02 in December 2025. I have two young children who ride in this vehicle regularly. Ford has acknowledged a safety defect that can cause an engine stall while driving, has provided no interim safety accommodation, and has not responded to my follow-up correspondence in over a week. I am requesting that NHTSA review Ford's handling of this recall and the adequacy of Ford's response to affected owners. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
