Ford Super Duty Lemon Law

The 6.7-liter Power Stroke diesel is the heart of the Super Duty, and it is also the source of one of Ford's most serious recent recalls. Ford recalled roughly 295,000 model year 2020–2022 F-250, F-350, F-450, F-550, and F-600 trucks (NHTSA 24V957) because deposits from aged biodiesel can form on the high-pressure fuel pump, increasing wear, introducing metal debris into the fuel system, and potentially causing sudden loss of engine power or stalling — a crash risk. Ford's remedy reflashes the powertrain control module, but owners who experience repeat stalling or a fuel system that never runs right may have a Lemon Law claim.

Beyond the fuel pump, Super Duty owners report other substantial defects: TorqShift transmission harsh shifting and slipping, diesel emissions and DEF system faults that trigger limp mode or countdown-to-no-start warnings, turbo and injector problems, and electrical faults. Any of these can qualify a truck as a lemon when a dealer can't fix it. Because many Super Duty trucks are used for work, it is worth knowing that California's Lemon Law can cover business and commercial vehicles: a vehicle used for business qualifies if its curb weight is under 10,000 pounds and the business has five or fewer vehicles registered in California.

California's Lemon Law applies to a Super Duty still under Ford's warranty. If a substantial defect isn't fixed after a reasonable number of repair attempts — often four or more, or fewer for a serious safety defect like stalling — or the truck is out of service for roughly 30 or more cumulative days, you may be entitled to a buyback, replacement, or cash settlement, with Ford paying your attorney fees. Keep every repair order and record each day the truck is down, which matters even more when it costs you working time.

A recall is not automatically a lemon — it's the manufacturer acknowledging a defect and offering a free repair. California's Lemon Law (the Song-Beverly Act) comes into play when a substantial defect can't be fixed after a reasonable number of attempts, or when your Super Duty has been out of service for 30 or more cumulative days.

If your Ford Super Duty qualifies, you may be entitled to a buyback (a refund of what you've paid, minus a mileage offset), a replacement vehicle, or a cash-and-keep settlement — and Ford pays your attorney fees on a successful claim, so pursuing your case costs you nothing out of pocket.
