The 2013 Ford F-550 SD has 5 recalls, the most serious being a fire risk on vehicles modified with certain power take-off assemblies, where oil leaking from the PTO pressure switch can soak into the exhaust's thermal blanket and ignite.
This fire risk appears across four separate recalls, each covering trucks upfitted by different equipment companies. The underlying problem is the same in each case: oil contacts a heat-soaked exhaust covering and can catch fire. The fifth recall affects trucks built with ambulance or fire engine preparation packages, where a transmission control software issue can cause the engine to shut down unexpectedly and require a cool-down period before restarting, potentially delaying emergency response.
