This page covers 12 recalls and 16 owner complaints for the 2021 Ford F-450 Sd.
The complaint picture for the 2021 F-450 SD is spread thin across 16 reports, but the electrical system draws the most attention. Owners describe the vehicle shutting down unexpectedly while moving, with power loss taking out brakes and steering simultaneously, one report ties this to metal contamination found in the high-pressure fuel system. The powertrain complaints include a transmission getting stuck in a high gear while descending a grade with a trailer attached, with the brakes responding weakly in the same event. A separate thread involves the truck's trailer brake controller failing to actuate electric-over-hydraulic trailer brakes, which owners describe as a significant reduction in stopping performance while towing heavy loads. Latches and locks account for two additional reports, though the narratives don't contain enough detail to describe a clear symptom pattern there.

By System
The 2021 Ford F-450 SD has 12 recalls, the most serious involving fuel system failures that can stall the engine or cut drive power, a steering column shaft that can detach and eliminate steering control, and front wheel hub extenders that can separate from the vehicle entirely.
The fuel concerns span both gasoline and diesel systems. On gasoline-powered trucks, the low-pressure fuel pump can fail and stall the engine. On diesel models, three separate issues affect fuel delivery: a pinhole that can develop in the secondary fuel filter cap and leak fuel near potential ignition sources, high-pressure fuel pump failure caused by biodiesel deposits that cuts drive power, and a follow-up recall for trucks where an earlier repair attempt for that pump issue was not completed correctly. On trucks equipped with a fifth wheel hitch, a cracked left-hand mounting bracket can allow the fifth wheel to detach while towing. The windshield may not be properly bonded and can separate in a crash. Visibility issues round out the list: the rearview camera can show a blank or distorted image, the 360-degree camera system can fail to display a proper image in certain lighting, and the windshield wiper arms can break and leave the wipers inoperative. There is also a documentation recall noting that the owner's manual omits instructions for adjusting certain head restraints.
