Ford Power Stroke Lawsuit Filed Over Defective Fuel Pumps

Back in May 2020, a lawsuit was filed claiming that 2011 and up Ford Super Duty trucks equipped with the Ford 6.7L V8 Power Stroke diesel were built with defective fuel pumps – Bosch CP4 high-pressure fuel injection pumps, to be more specific, which reportedly weren’t capable of handling U.S. diesel fuel specifications. This past July, another Ford Power Stroke lawsuit was dismissed, though this case claimed that affected trucks were built with emissions defeat devices. Now, the Ford Power Stroke diesel is the center of yet another legal battle related – once again – to defective fuel pumps, according to Car Complaints.

This new lawsuit claims that 2011-2017 Ford Super Duty pickups equipped with the 6.7L Power Stroke engine that were leased or purchased in South Carolina are also equipped with the aforementioned Bosch CP4 fuel pumps. Ford allegedly tried to conceal that part’s known defects, which can cause metal shavings to contaminate the fuel system.

The lawsuit claims that due to an unstable design, metal-on-metal contact can occur from day one with these particular fuel pumps, which is what leads to the metal shavings. The plaintiffs in the case claim that any diesel fuel can cause this problem, but it also points to the fact that U.S. diesel fuel is incompatible with this particular pump, as it doesn’t provide sufficient lubrication.

Faulty fuel pumps can cause all sorts of issues with diesel engines, ranging from over-fueling to broken injector tips to more serious issues like melted pistons, damaged turbochargers, and even hydraulic lock, according to the lawsuit. The plaintiff in the case states that damages caused by these faulty pumps can cost upwards of $10,000 to repair, and that owners who take their trucks to Ford will simply get the exact same part as a replacement.

    These pumps are still an issue. Diesels should be made to run reliably for 300k+ miles. We shouldn’t have to worry about a $10-12k repair bill because a pump fails. Can’t believe Ford hasn’t at least designed a filter in the filter path to catch the metal particles when there is a failure. Do better Jim Farley.

  2. James L Shelton

    We had this issue . Has metal shavings in engine somewhere around or little over 7500$ we had to have repaired

  3. Roger

    This problem is not just limited to Ford
    Gm used the same pump from 2011 thru 2016. Many failures and no help from GM

  4. JDE

    GM has the same issue. CP4 pumps. seems like maybe Bosch blue the smoke up both companies Skirts, and Bosch should be footing the recall bill.

  5. Jeff Harris

    They’ve been having this problem way before then Last time it cost me $11000 at the dealer to fix it On a 6 point Four-power stroke Should have been recalls on all this but they don’t care

    1. James

      Yep I agree. My 6.4 has the same issue. I know ford knows because of the computer reprogram that rased the fuel pressure limit instead of replacing the pump. The only difference is no one with money to pay lawyers must have owned the 6.4s

  6. James Wilson

    We had the same problem in June of 2022. Left us stranded on the road in middle of Montana. Had to have the whole fuel system replaced, engine torn apart and gas tank dumped and rinsed at a tune of over $18,000! Thank God Ford honoured our warranty. But, ours is a 2018 350 Superduty dually.

  7. Steve

    Have two fords with the 6.7 2022, 2021
    Installed the S&S disaster prevention kit on both that adds the filter to catch the metal shavings. Also prevent major damage.
    800. Each installed is peace of mind.

  8. Shane

    I how do I get in on this law suite, I’ve been without a truck for over four months, 37k to get fixed when Possible/available parts come in due to pump causing engine to blow.

  9. Michael

    Ford has had ongoing issues starting in 2003 with 6.0 head gaskets. They knew this was a problem but still keep producing a bad product to gain $ from the consumers. Every customer should have been refunded on these vehicles that had issues along with the 6.4 that were no better. Every customer should get refunded and compensated for these bad fuel pumps as well.

    1. Sean

      6.0 was an international engine. 6.7 is the first fomco diesel engine. And I love mine no problems 114k

  10. Ben

    Dealer wants $17k to fix mine. 2020 with 32000 miles on it. Warranty rejected for contamination in the fuel lines. Still not sure on how a part of the fuel system can contaminate the rest of the fuel system and it’s not covered. Feel real sorry for the fleet guys who have had several trucks out. Seems like Dodge is the only people that have really looked to take care of their customers on this one. Sad.

  11. JB

    Is there a way to get on the claims lawsuit? Had to pay 17k and insurance wouldn’t cover it.

  12. Thomas Reek

    I would like to know how to join a class action lawsuit for the CP4 pump if anyone knows of one.

  13. Thomas R

    Maybe everyone on here should get together and see if we can start a class action lawsuit.
