Summary
The Ford F-550 Super Duty has 5 recalls spanning 1994 to 2021, with the most serious recent issue affecting 2021 models where improperly tightened front wheel hub extender nuts can allow a wheel to fully separate from the vehicle, causing loss of control or striking other vehicles or pedestrians.
The 2018 model year has a compliance recall where the owner's manual omits instructions for removing or adjusting the head restraints at the centre seating positions, which can leave occupants without guidance that affects injury risk in a crash. On 2009-2013 models equipped with Versalift aerial devices on 6.8L gas engine chassis with Muncie Power Products FR67 PTO assemblies, oil can leak from the PTO pressure switch onto a thermal blanket covering the exhaust and ignite a fire. The 2003 model year has a loose battery ground stud that creates high electrical resistance, causing current to reroute through the radio suppression strap, which can overheat, melt, and ignite nearby components. Going back to the earliest production, the 1994 model year has a speed control deactivation switch that can overheat, smoke, or catch fire in the engine bay whether the vehicle is parked or running.
