Ford Super Duty diesel high-pressure fuel pump may fail

NHTSA campaign 26V158000 · Reported 2026-03-17 · Ford Motor Company

high How serious is it? About this label

Losing power while driving can lead to a crash, so this should be handled soon; the notice does not tell owners to park the truck.

What's wrong, in plain English

These heavy-duty Ford trucks were repaired under an earlier recall, but that fix was not done correctly. Deposits from biodiesel fuel can build up on moving parts inside the high-pressure fuel pump and cause the pump to fail. If that happens, the truck can lose engine power while you are driving. Dealers will update the engine computer software for free. Your truck needs this even though the earlier recall work was already done.
