What can fail
Biodiesel deposits can build up on the fuel pump's internal roller parts, potentially causing the high-pressure fuel pump to fail.
The 2020 Ford F-550 SD has 8 recalls, the most serious involving transmission and fuel system problems that can cause the vehicle to roll away unexpectedly or lose drive power while moving.
The transmission has two separate concerns: a disintegrating washer can scatter metal debris into the Park mechanism, preventing the transmission from holding Park and creating a rollaway risk, and a brittle torque converter damper plate can fracture and cause the engine to stall or reduce braking effectiveness. The high-pressure fuel pump can fail due to biodiesel deposits building up on internal components, cutting drive power without warning. One of the fuel pump recalls specifically covers vehicles where an earlier repair attempt did not fully resolve the problem.
On the visibility side, the windshield may not be properly bonded and can separate in a crash, and the wiper arms can break and leave the wipers inoperative in rain or snow. The rearview camera can also intermittently show a blank or distorted image when backing up.
There is also a documentation recall: the owner's manual for SuperCab models does not include instructions for adjusting or removing certain head restraints, which can lead to improper positioning that raises injury risk in a crash.
