NHTSA (USA)Medium Risk
At a glance
What can fail
The exhaust gas temperature sensor may report a false overheating condition, causing the engine management system to shut down the engine and prevent immediate restart.
What the fix does
The 2011 Ford F-550 SD has 6 recalls, the most serious being a fire risk affecting trucks that were upfitted with 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 upfitter recalls covering trucks modified by different specialty equipment companies, but the underlying hazard is the same in each case. There is also a concern for vehicles modified to carry wheelchair lifts by Farber Specialty Vehicles: a side plate on the lift platform can crack, causing the platform to separate and drop against the vehicle's lift door, which could leave a wheelchair user unsupported. On the drivetrain side, trucks built with ambulance or fire engine preparation packages have a transmission control issue that can cause the engine to shut down unexpectedly, requiring a cool-down period before restarting and potentially delaying emergency response.
