2011 FORD F-550 Recalls — Canada & USA

The 2011 Ford F-550 has 6 recalls, the most serious involving fire risks from fuel system failures: CNG-converted transit buses may shed a fuel tank from the frame, and certain PTO-equipped trucks with 6.8L gasoline engines can leak oil onto exhaust components and ignite. The CNG tank issue affects vehicles converted by Almared/A-1 Alternative Fuel Systems, where the mounting brackets on the passenger side tank can break and allow the tank to separate from the frame entirely, raising the risk of both a crash and fire. The PTO oil leak appears across several upfitter recalls covering the same underlying problem: a pressure switch in the power take-off assembly drips oil onto a thermal blanket wrapped around the exhaust, where heat can cause it to catch fire. This affects trucks built or modified by multiple equipment companies. Two recalls affect certain ambulance-package vehicles with 6.7L diesel engines. In both, a fault in the exhaust gas temperature sensor triggers a warning message and audible chimes while the engine progressively loses power. In the more severe case, the engine can stall completely once vehicle speed drops below roughly 3 mph; in the less severe case, torque is reduced by about 70 percent and held at that reduced level.
