The 2018 Ford F-550 SD has 3 recalls, the most serious being a risk of fire inside the cabin on SuperCrew Cab models with carpet flooring, where sparks from a deploying front seatbelt pretensioner in a crash can ignite carpeting or insulation near the B-pillar.
There is a second fire risk on trucks equipped with an engine block heater that were previously repaired under an earlier recall: the splice connector on the block heater cable may have been damaged during that prior repair, causing the wiring to overheat or melt. The third recall covers the rearview camera, which can display a distorted, inverted, or blank image when the vehicle is in reverse, reducing the driver's view of what is behind the truck.
