The loudest Super Duty year — and death wobble is why. Inspect the front end hardest here.

Recall 18V-802 (Ford 18S36) is unique to the 2019 Super Duty: an incorrect transmission-case casting may leave the park-pawl assembly unsecured, so the truck can move even when shifted to Park — a rollaway risk. The remedy is a transmission inspection and, if needed, replacement, free of charge. This is the single most important recall to confirm remedied on a 2019. On your test drive, park on a slope, shift to Park, and confirm the truck holds without creeping before you release the brake.

The diesel's defining risk continues. The Bosch CP4.2 high-pressure fuel pump can run dry, make metal, and contaminate the entire high-pressure system — pump, injectors, lines, and the fuel conditioning module — so a failure means a roughly $10,000 full-fuel-system replacement (mechanic-quoted). Triggers are contaminated fuel, missed filter services, and misfueling (gasoline or DEF in the diesel tank). Pull the lower fuel filter, look for metal glitter, and get the fuel-filter service history before you buy.

2019 is the last year of the 6.2L Boss V8 before the 7.3 Godzilla arrives. It carries the same '$3,500 misfire job' reputation (16 plugs, 8 coils, intake-manifold runners) a Ford tech describes in our sources. It is a durable tow engine, but ignition work is expensive. Ask for plug and coil history and use any persistent misfire as a bargaining point.
