Ford F 350 Super Cab
Problems & Worst Years

Neither year in the Ford F-350 Super Cab's file is heavy — 90 reported occurrences for 2020 and 75 for 2021 — but the two read differently. The 2020 list is led by transmission failure producing unexpected shifts and loss of power (27 reports), nearly a third of the year's total, with fuel system malfunction second at 14. Its two safety-severity items are steering-related: death wobble at highway speeds (10 reports) and a steering column defect (8). Tailgate malfunction rounds things out at 7.

The 2021 file has no safety-severity problems at all and scatters across small counts: an electrical short causing unpredictable malfunctions (14), back-over prevention system faults (13), engine performance issues (13), and high-pressure fuel pump failure (11). Another nine reports concern fuel system recall issues — owners frustrated about recall handling rather than a fresh mechanical failure — so confirming completed recall work belongs on the checklist.

Fuel delivery is the thread joining the two years; between the 2020 malfunction reports and 2021's pump failures, it's the system to ask about first. For a 2020 specifically, judge the transmission over a long test drive — cold start through highway — and take the truck to speed over uneven pavement to check for any front-end oscillation, with a mechanic's eye on the steering column. For a 2021, run the electronics through a full cycle and verify the backup camera and its warnings behave.

At these volumes, the data is a direction-finder, not a verdict. Complaint counts reflect what owners filed with NHTSA rather than measured failure rates, and the newer year's smaller file partly reflects less time on the road. The specific truck's service records and a competent pre-purchase inspection matter far more than the choice between these two years.
