Ford 6.7 Diesel Lawsuit & CP4 Fuel Pump Recall Update 2025

If you own a Ford diesel truck, you should be aware of potential engine issues, particularly with the CP4 fuel pump.

Some Ford diesel trucks have been found to contain defective fuel injector pumps, which can cause significant engine damage over time.

Many Ford owners have reported complete engine failure, a costly and disruptive problem. Repairing such damage can exceed $10,000, leaving drivers with not only the inconvenience of extended downtime but also the financial burden of extensive repairs.

Ford’s analysis of returned parts has revealed signs of aged biodiesel deposits, prompting further investigation into the effects of biodiesel availability.

In September 2024, Ford’s assessments linked the geographic availability of bio-diesel and average state temperatures to the frequency of engine failures.

As of November 13, 2024, Ford has received 3,070 warranty reports, 498 field reports, and 58 customer service reports about this issue, spanning from October 18, 2019, to November 12, 2024.

Despite these findings, the company has not issued a recall or provided a long-term solution for the Ford 6.7L engine problem.

2024 Ford 6.7 Diesel Recall

In December 2024, Ford recalled 295,449 of its 2020–2022 F-Series Super Duty trucks equipped with 6.7-liter diesel engines due to a fuel pump issue.

The high-pressure fuel pump (HPFP) in these trucks can accumulate deposits from biodiesel, which may eventually cause the pump to fail. 

A failed fuel pump can result in engine power loss or engine stalling, creating a higher risk of a crash.

The 2024 recall includes 2020–2022 F-Series Super Duty trucks, specifically the F-250, F-350, F-450, F-550, and F-600 models. It also affects the 2021–2022 F-650 and F-750 trucks. Below is a look at the breakdown of this recall:

Ford has previously attempted to address this issue by introducing a redesigned fuel pump in August 2021, featuring a larger roller shoe and greater tappet body clearances to help prevent deposits from building up and causing damage.

To find out if your vehicle is affected, you can check your Vehicle Identification Number (VIN) and obtain more information by calling Ford at 800-392-3673, reaching the National Highway Traffic Safety Administration’s (NHTSA) vehicle safety hotline at 888-327-4236, or visiting the NHTSA website.

Ford Diesel Lawsuit Overview

In December 2022, a class action lawsuit was filed against Ford, accusing the automaker of selling thousands of diesel trucks equipped with defective fuel injection pumps that could lead to catastrophic engine failures.

The heart of the lawsuit centers on allegations that Ford sold numerous diesel trucks with faulty high-pressure fuel injection pumps (CP4 pumps) supplied by Bosch.

These pumps, found in vehicles with 6.7L Power Stroke diesel engines, are said to have a design flaw that results in metal shavings contaminating the fuel system, leading to engine failure.

The issue affects models from 2011 onward. Plaintiffs argue that Ford was aware of the defect but failed to take proper action, leaving truck owners with expensive repair costs.

The lawsuit primarily targets Ford trucks with 6.7L Power Stroke diesel engines, particularly those from model years 2011 and later.

According to the lawsuit, Ford produced and sold these trucks knowing the high-pressure fuel injection pumps were defective. This case is officially known as Keith T. Williams et al., v. Ford Motor Company.

How do I know if my Ford Truck is affected?

To find out if your Ford truck is part of the recall, you can check using your Vehicle Identification Number (VIN).

Simply visit the Ford recall website, use the FordPass app, or contact your local Ford dealer to inquire about any potential recalls specific to your vehicle.

What makes and models are affected?

Ford is recalling certain F-Series Super Duty and Medium Duty trucks equipped with the 6.7-liter Scorpion diesel engine due to an issue with biodiesel deposits. The recall affects a total of 295,449 vehicles, including the following models:

• 2020-2022 Ford F-250 Super Duty
• 2020-2022 Ford F-350 Super Duty
• 2020-2022 Ford F-450 Super Duty
• 2020-2022 Ford F-550 Super Duty
• 2020-2022 Ford F-600 Super Duty
• 2021-2022 Ford F-650
• 2021-2022 Ford F-750

These trucks, particularly those with 6.7-liter diesel engines, are at risk due to the dangerous buildup of biodiesel deposits, which can ultimately lead to serious engine failure.

What is the life expectancy of a Ford 6.7 diesel engine?

The Ford 6.7L Powerstroke diesel engine is known for its durability and can last between 200,000 and 300,000 miles on average.

However, with consistent and proper maintenance, this engine can reach 400,000 miles or more, making it a reliable choice for many truck owners.

To help ensure the longevity of your 6.7L Powerstroke engine, here are a few key maintenance tips:

• Regular Maintenance: Routine servicing is crucial for extending the life of your engine. Pay particular attention to components such as the turbocharger, exhaust system, and fuel injectors, as they play a critical role in performance.
• Oil Changes: It’s important to change the engine oil regularly to ensure smooth operation. Aim for oil changes every 5,000 to 7,500 miles to keep the engine running efficiently.
• Fuel Filter Replacement: The fuel system in diesel engines is sensitive to contaminants. Change the fuel filter every 15,000 miles to ensure the engine receives clean fuel, which helps prevent performance issues.
• Coolant System Care: Maintaining the cooling system is vital to prevent the engine from overheating. A well-functioning cooling system helps avoid potential damage and ensures the engine operates at optimal temperatures.
• Upgrades and Modifications: Upgrading components like the head gaskets and studs, as well as installing a cooler kit, can reduce wear and tear on the engine. These improvements can help prevent breakdowns and enhance engine performance.

These issues are most pronounced in the first generation (2011–2014). When the injection pump fails, it can spread debris throughout the fuel system, potentially causing further damage.

Proper maintenance and timely repairs can help mitigate these problems and extend the life of your engine.

Who can join the lawsuit?

If you own or lease a Ford truck with a 6.7L engine, it’s important to carefully review your options before deciding whether to join the Ford CP4 lawsuit or pursue a lemon law claim.

Keep in mind that by joining the class action, you may give up the right to file an individual lemon law claim.

Once you become part of the class action, any judgment or settlement reached will apply to you, and you will not be able to pursue a separate claim through the lemon law process.

To ensure you make the most informed decision for your specific situation, it’s advisable to consult with an experienced lemon law attorney.

They can guide you through the legal process, help you understand your rights as a consumer, and assist in determining the best course of action based on the details of your case.

How do I get Ford to buyback my car?

If you’re seeking a buyback from Ford for your vehicle, you can start by contacting Ford customer service to report your vehicle’s issues.

Consulting a lawyer who specializes in lemon law may also help you navigate the process and determine the best course of action for your situation. Here are the key steps to take:

1. Contact Ford customer service
   Call Ford customer service at (866) 231-1173 and follow the prompts to connect with the claims department.
2. Document issues
   Keep detailed records of all communications with both Ford and the dealership. Make sure to note repair attempts, dates, and when the issue reoccurred.
3. Consider consulting a lawyer
   A lawyer specializing in lemon law can help assess your eligibility for a buyback and guide you through the process, ensuring you understand your rights and options.
4. File a claim
   If your vehicle qualifies as a lemon, send a certified letter to Ford outlining the issues with your vehicle and the repair attempts made. This will serve as your official claim.

Ford may agree to buy back your car for various reasons, including the unavailability of parts to fix minor issues, a desire to maintain a positive relationship with loyal customers, or because there’s a legitimate concern requiring extra attention from Ford engineers.

If you’re seeking a lemon law buyback, you must follow the lemon law process specific to your state.

These state-specific laws offer protection against defective vehicles, potentially entitling you to a refund or replacement vehicle from the manufacturer.

In most cases, the vehicle must have a significant defect or recurring problem covered under warranty that affects its use, value, or safety.

Additionally, you must have allowed the manufacturer a reasonable number of attempts to fix the issue, and they must have been unable to resolve the problem within a reasonable timeframe or a specified number of repair attempts.

Finally, you must notify the manufacturer in writing and give them a final opportunity to repair the issue before pursuing legal action.

If you believe your case meets these criteria, it’s a good idea to consult a lemon law attorney in your state.

They can assist you with preparing the necessary documentation and help negotiate with Ford to reach a resolution.

Should I Pursue a Lemon Law Case or a Class Action Settlement?

If your vehicle has significant defects that affect its safety, use, or value, and you are the sole owner, pursuing an individual lemon law claim might be the best option for you.

Given that Ford is facing substantial recalls, it’s clear that the company is dealing with widespread issues.

When you file an individual lemon law claim, you can pursue a refund or replacement vehicle from the manufacturer.

Your case will be evaluated on its own merits, which may result in greater compensation than what you could receive from the Ford 6.7 diesel class action settlement.

An individual claim allows for more flexibility and the potential for a larger payout, as it’s not bound by the limits typically associated with a class action.

Moreover, an individual claim gives you more control over your case. You’ll be able to negotiate directly with the manufacturer and their legal team, allowing you to present your evidence and arguments effectively.

This personalized attention can increase the chances of a favorable outcome and lead to a quicker resolution compared to the often drawn-out and complex process of a class action lawsuit.
