Ford Super Duty Lawsuit Filed Over Defective Fuel Pumps

The Ford Super Duty has certainly been the subject of its fair share of lawsuits over the years, with most of the recent ones pertaining to a roof crush issue, though the popular pickup has also been targeted over things like “death wobble,” non-working power tailgates, diesel emissions concerns, and the fuel pumps used on models equipped with the 6.7L V8 Power Stroke engine. Now, yet another defective fuel pump lawsuit has been filed, and once again, it’s related to Ford Super Duty models equipped with the 6.7L Power Stroke diesel engine, according to Car Complaints.

The lawsuit – David Clark v. Ford Motor Company – was filed in the U.S. District Court for the Eastern District of Michigan by a plaintiff represented by Hilliard Law, Hagens Berman Sobol Shapiro LLP, and The Miller Law Firm. It pertains to trucks equipped with the 6.7L Power Stroke diesel that were produced in and after 2011, which are equipped with high-pressure Bosch CP4 fuel pumps that are reportedly defective.

This new lawsuit claims that these fuel pumps contain metal parts that rub against each other, creating friction and sending metal shavings into the fuel system, which eventually destroys not only that system, also the engine itself. The lawsuit also alleges that U.S. diesel fuel doesn’t properly lubricate engines equipped with this fuel pump, and instead, wears down the cam and rollers and results in even more metal shavings – leading to a costly engine replacement tab of around $10,000.

Ford Super Duty

The plaintiff in the case – Texas native David Clark – experienced this problem in his 2020 Ford Super Duty when it had just 23,000 miles on the clock, as the truck went into limp mode and stalled. After having it towed to a nearby dealer, Clark discovered that the CP4 fuel pump was indeed the culprit, but Ford rejected his warranty claim, which totaled $12,838 for the engine and other related expenses.

    This from FORD. The company that prides themselves on their trucks. Of course the POWERSTROKE isn’t exclusive to the SUPERDUTY pickups and chassis cabs. This is going to hit many medium (650-750) users too.

    Damn Ford, figure this out already! Over 10+ years and they are still using a ticking time bomb for a fuel pump.

      Ours blew up on August 15th 600 miles from home and the dealership in KY said it was because of water in the fuel. It was a 2019 F-450 with 51,000 miles. With towing, to include towing our camper home , we spent close to $13,000. Thankfully we just traded it in for a new Dodge Ram 3500. Ford is trying to settle with us for $650 🤣🤣🤣🤣 We will never buy another Ford again.

    They denied the warranty claim more than Likely evidence of rust from water contamination in the fuel. Otherwise they would have warranted it. However they do need a better water separator if the system is that sensitive to water.

      If you change your fuel filters (2) after every oil change you won’t have that problem.

        Totally agree – 2 powerstrokes and well over 100k miles and never a fuel problem! Change filters when scheduled!

      The CP-4 pump has inherent design issues. It has been a problem since it’s inception. The issue isn’t with water, or fiktersir anything like that. Look into the pump and what makes it so bad. It’s just a bad pump and a bad design.

        Doesn’t it have iron pistons and aluminum block? Mine went out on a Sunday afternoon.250 miles from home, $1300 flatbed tow bill. Bought new CP4 from Ford, they have such little confidence in them that they don’t offer a warranty on them.

        Correct.

      Exactly! If there is rust on the pressure control valve, it’s because of water. Otherwise, Ford has no problem paying the claim. I admit the water separator is somewhat small. However, it does work fine unless there was more than the average amount of water in the fuel.

    FoMoCo should be helping their customer’s, not dismissing them, if the pump’s are faulty FoMoCo should be suing Bosch for all the warranty claims, so much for German engineering.

    I feel your pain, last yr, my wife’s Ford Edge, had a engine failure alarm and I took it to our Ford dealership and found out that the crappie 2.0 4cyl engine had a dead cyl from water leaking into the cyl. Of course as I learned about what caused the problem. The thickness of the cyl wall was so thin that it was destined to fail. And that Ford was claiming that it was not their fault. Our car was only 4 yrs old and only 6000 miles out of warranty. They paid $0000.00, I pd nearly $6000, out of pocket. I have been a life long Ford man, but this has left a real bad taste in my mouth. It will be by the powers (the lottery) might make it a little more easier to buy another. Not a dime, anything would be very good, but not to reach out to us with some kind of plan to make it look like they care. Thanks

    Gave up on Ford years ago. Lots of problems. Always performed timely maintenence with records. Ford ALWAYS denied any responsibility and all warranty claims. Enough is enough. All manufacturers have problems, but others are more willing to help than Ford.

    I’ve been driving Ford heavy duty trucks, including three Diesels, since 1988. They have faithfully carried me and done the job. I think a lot of the whining is from problems related to abuse, modifications, and neglect.

      Bought a new ford truck in 1996 bumper to bumper warranty 3 year or 36,000 on the fuel pump switch two tanks tag says fuel pumps not covered and not to drive around low on fuel . 295,000 3 fuel pumps later.

      Better if you look into the CP-4 pump and it’s faulty design. No amount of proper maintenance will do anything for it. The pump is a bad design and Ford refuses to go with a different pump. This problem land completely on their shoulders.

    We have a farm and have purchased around 15 trucks from Ford in recent years. Mostly Superduty’s, some dually and som SWR, some with gas motors and others with diesel motors. That’s not including what my sons and daughters purchase. I wanted to order a new F450 diesel this spring but held off because Ford won’t stand behind the CP4 problem. The excuses of water in the fuel don’t cut it. Every tractor, bulldozer and diesel truck I have has a water separator that works and those engines aren’t going bad. My old 7.3 turbo is still going strong and the water separator works great. Ford is really hurting themselves. Once they loose my trust, and they have. I will switch brands and never go back. I use to be 100% Chevy before I switched to Ford. I will be ordering a new Dodge before winter.

        I’m a Ford guy. And I’ll be the first to say that the Cummins is a way better engine than today’s Powerstroke. Ford really tried hard to get it right with the 6.7, especially after Navistar literally left them hanging with the 6.0 and 6.4. But, the engine is plaqued with quite a few problems as well as a really bad choice of injection pump.

    The CP4 pump failed on my 2021 F450 King Ranch with 30K miles. Every service to include oil change , fuel filter change , cabin filters, air filters and tire rotations were done at the dealership. NO ONE else has ever touched my vehicle. First, they claimed I used regular unleaded gas, then after showing them the receipt they said it was bad diesel. Ford denied the claim even after my insurance company tested my fuel and assured them is was in fact diesel used. Ultimately I ended up pay $10k for the entire fuel system. There is no FIX there is no preventive maintenance without voiding your warranty which they don’t even honor in the case of this Bosch CP4 pump. I have owned a Ford F150, F250, F350 and Ford Flex. I have NEVER had any mechanical issues until now ! Ford doesn’t stand by their product and I am done standing by them.

    Yet with a fleet of 50 superduties from 2011 till now we have not had one fuel pump failure in 10+years and trucks replaced at 150k miles. Always changed filters on time with OEM filters. Hmmmmmm………

    Ford is in trouble on this one. Maybe they need to look at who is building their parts. Foreign made parts are more than likely the problem. Bring it back to the USA and let’s get back to driving.

    The same exact thing happened to my truck. Ford in Charlotte, NC tried to say I got bad fuel somewhere. My whole family drives diesel and we all use the same gas station and have for years. Never had an issue. The ford tech said I had metal and rust in the fuel system. About 12,000 total. Tried to explain to them the issue with the CP4. They wouldn’t listen. Just kept saying poor fuel. Luckily insurance covered the cost. But I’m still having fuel issues. Does anyone have any advice?

      Your automobile insurance covered it ??? We did t even think about that. We just paid after Ford declined our warranty claim.
