2018 Ford F-150 (3.0L Power Stroke Diesel) — Should You Buy One?

Typical asking price: $24,000–$36,000. There is 1 high-severity known issue you need to know before handing over a check.

Kestrel Take

A half-ton diesel that returns genuine 27-mpg highway numbers and tows 11,000 pounds. Ford discontinued it after 2021 because almost nobody bought one. That makes it a depreciated bargain and a parts-support question at the same time.

Ranked by wallet impact. These are documented, recurring problems — not freak accidents.

Emissions system (DPF, EGR, DEF) failuresHigh — wallet impact

Discontinued powertrain supportMedium

Ford ended the 3.0L diesel F-150 after 2021. Sales volumes were small, so dealer familiarity and independent shop experience are limited.

Turbo and EGR cooler soot accumulationMedium

Soot binds the variable vanes and clogs the EGR circuit, causing underboost and reduced power.

Fuel filter service interval disciplineMedium

Skipping fuel filters on a common-rail diesel risks injector and pump damage.

Repair cost range: $120 service, $4,000+ injectors
