2015 Ford F-250 Super Duty (6.7L Power Stroke) — Should You Buy One?

Typical asking price: $28,000–$42,000. There is 1 high-severity known issue you need to know before handing over a check.

Kestrel Take

Ford's own diesel, designed in-house after the Navistar divorce, and by 2015 it was sorted. This is the Super Duty to buy. The single genuine catastrophe risk is the CP4 fuel pump, and when it goes it takes the whole fuel system with it.

What we checked

Partly reconciled against public records, 2026-09-11

NHTSA holds 592 owner complaints for the 2015 Ford F-250 Super Duty (6.7L Power Stroke), and no recall campaigns.

A big number here usually means a lot of these were sold, not that it is a bad vehicle — popular models collect more complaints for the same rate of trouble. So the total on its own says little. What is worth reading is the shape of it. 43% of them are about one thing — steering. That much concentration is a genuine pattern rather than background noise, and it is the first thing to check on any example you look at.

Not written up yet: steering (252 complaints), the suspension (248 complaints). Those groups are in the public record and are not covered by the issues below. Treat them as something to ask about, not as absent.

Counts come from the NHTSA complaint and recall database — free, public, and worth checking yourself.

Known Issues for the 2015 Ford F-250 Super Duty (6.7L Power Stroke)

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

Bosch CP4.2 high-pressure fuel pump failureHigh — wallet impact

The CP4 runs on diesel fuel for lubrication and American fuel is drier than it likes. When the pump self-destructs it sends metal through the injectors, rails, lines, and tank. Every fuel component must be replaced.

Repair cost (estimate): $8,000-$12,000

Source: NHTSA complaints filed under the fuel system (70).

Turbocharger bearing and VGT failureMedium

The variable geometry turbo sticks from soot buildup, causing underboost codes and reduced power.

Repair cost (estimate): $2,000-$4,000

Source: NHTSA complaints filed under the engine (92), wheels and bearings (44).

EGR cooler and DPF cloggingMedium

Short-trip use prevents complete regeneration, clogging the filter and eventually derating the truck.

Repair cost (estimate): $1,000-$3,500

Source: NHTSA complaints filed under the engine (92).

Glow plug and injector wearMedium

Hard cold starts and rough running from failing glow plugs or worn injectors.

Repair cost (estimate): $800-$3,500

Source: NHTSA complaints filed under the fuel system (70), wheels and bearings (44).

✗Short-trip-only history
✗Heavy commercial towing with no service records

Good Signs
