This page covers 2 recalls and 16 owner complaints for the 2020 Ford F-550.
Complaints for the 2020 Ford F-550 center most heavily on the diesel fuel system and powertrain. On the fuel side, owners report fuel injector failures that trigger a check engine light and leave the truck underpowered or stalled; one report describes a post-service engine fire with smoke and flames visible under the hood after an oil and filter service. Powertrain complaints include the transmission failing to hold in park, allowing the truck to roll unintentionally, along with violent jerking during uphill driving and hard downshifts between gears. A separate engine complaint describes a valvetrain failure, specifically a roller lifter bearing collapse around 93,000 miles, that required a full engine replacement. The complaint volume here is relatively small, so these issues reflect individual owner experiences rather than a broad pattern, but the fuel injector failures and transmission behavior show up across more than one report.

By System
The 2020 Ford F-550 has two recalls, the more serious being a rear axle differential that may have insufficient fluid, which can cause the axle assembly to fail and the driveshaft to separate, resulting in sudden loss of drive.
The second recall affects trucks equipped with manual front seat recliner mechanisms: the recliner can be improperly assembled, leaving the seat back with reduced strength that may not hold an occupant in place during a crash.
