Ford Diesel Fuel Pump Recall: What Every Super Duty Owner Needs to Know in 2025-2026

If you own a 2020-2022 Ford F-Series Super Duty truck equipped with a 6.7L diesel engine, your vehicle is part of a major safety recall involving the high-pressure fuel pump. Ford has recalled approximately 295,449 vehicles in the United States because biodiesel deposits can build up on the pump's drivetrain roller components, potentially causing the fuel pump to fail and leading to a sudden loss of drive power while driving—which increases the risk of a crash. The good news: Ford is providing a free software update to fix the problem. But there is more to this story, including a follow-up recall in 2026 for vehicles that received an incorrect repair the first time. Here is everything you need to know, step by step.

The Core Problem: Biodiesel Deposits and Fuel Pump Failure

The recall stems from a specific issue with the high-pressure fuel pump on diesel-powered Super Duty trucks. According to the National Highway Traffic Safety Administration (NHTSA), biodiesel deposits can form on the pump drivetrain roller components. Over time, these deposits cause increased wear inside the pump, introducing metal debris into the fuel system. When the pump fails, the engine may lose power completely, which creates a serious safety hazard on the road.

Ford's investigation traced the root cause back to the COVID-19 pandemic. Many trucks sat parked for extended periods before delivery, allowing the biodiesel in the fuel to age and form deposits inside the pump. The problem was first spotted in September 2021 when Ford's engineering team noticed an increase in warranty claims related to high-pressure fuel pump failures on 2020-2021 Super Duty and medium-duty trucks equipped with diesel engines. The fuel pumps were supplied by Bosch.

Which Vehicles Are Affected by the Initial Recall (24V957 / 24S78)

The original recall, filed with NHTSA on December 20, 2024, covers the following models and years:

  • 2020-2022 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
  • 2021-2022 Ford F-650
  • 2021-2022 Ford F-750

All these vehicles are equipped with the 6.7L diesel engine. Ford estimates that about 4% of the 295,449 recalled trucks actually have the condition. The affected trucks were built between February 19, 2019, and August 23, 2021. Ford introduced a redesigned fuel pump with larger roller shoe and tappet body clearances into production on August 23, 2021, which helps prevent the biodiesel deposit buildup.

What Symptoms Should You Watch For

If your truck's high-pressure fuel pump is starting to fail, you may notice one or more of these warning signs:

  1. Extended cranking time when starting – The engine takes longer than usual to fire up.
  2. Check Engine Light (CEL) illuminates – The dashboard warning light comes on.
  3. Unusual noise from the engine – You may hear ticking or knocking sounds.
  4. Reduced engine power – The truck feels sluggish, especially under load or during acceleration.

If you experience any of these symptoms, do not ignore them. A complete fuel pump failure can cause a sudden loss of drive power, which significantly increases the risk of a crash.

The Official Fix: Free PCM Software Update

Ford's remedy for the initial recall is straightforward. Dealers will update the Powertrain Control Module (PCM) software free of charge. The updated software increases pump cooling and helps prevent the formation of aged biodiesel deposits. This is not a hardware replacement—it is a software reflash that changes how the fuel system operates to keep the pump running cooler and cleaner.

Owner notification letters for the original recall were mailed starting January 13, 2025. Ford's recall number for this campaign is 24S78, and the NHTSA campaign number is 24V-957. If you have questions, you can call Ford customer service at 1-866-436-7332.

The 2026 Follow-Up Recall: 26V158000 / 26S17

Here is where things get more complicated. On March 17, 2026, Ford issued a second recall—NHTSA ID 26V158000, Ford campaign number 26S17—affecting certain vehicles that were previously repaired under the original recall 24V957. According to Transport Canada, the recall repairs completed during the first campaign "may not have been done correctly" on some vehicles, requiring a second repair.

This follow-up recall affects approximately 7,105 vehicles, including: 2020-2022 F-Super Duty F250, F350, F450, F550, 2021-2022 F600, and 2022 F750 vehicles. Owner notification letters for this second recall were mailed on April 7, 2026. The fix is the same: dealers will update the PCM software again, free of charge.

If you own one of these trucks, you need to check whether your vehicle is affected by either recall—or both.

How to Check If Your Truck Is Affected

The easiest way to find out if your specific vehicle is included in any recall is to look up your Vehicle Identification Number (VIN). You can do this in two ways:

  1. Visit NHTSA.gov/recalls – Enter your 17-digit VIN to see all open recalls for your vehicle.
  2. Call Ford directly – Contact Ford customer service at 1-866-436-7332 and provide your VIN.

VINs for the 2026 follow-up recall became searchable on NHTSA.gov on March 18, 2026. If your truck was part of the original recall, it is worth double-checking to see if it also needs the second repair.

What This Means for You as an Owner

If your truck is affected by either recall, here is what you should do:

  1. Confirm your VIN is on the recall list.
  2. Contact an authorized Ford or Lincoln dealer and reference the recall number (24S78 for the original, 26S17 for the follow-up).
  3. Schedule an appointment to have the PCM software updated. The repair is free, and federal law requires the manufacturer to fix the defect at no cost.
  4. If you already paid for a related repair under warranty, Ford will reimburse you.

Do not wait. Even if your truck is not showing symptoms, the software update is designed to prevent future problems. A sudden loss of power on the highway is not something you want to experience.
