This page covers 3 recalls and 13 owner complaints for the 2012 Ford F-550.
Engine complaints dominate what owners report for the 2012 Ford F-550. The most common pattern involves the engine stalling unexpectedly while driving or at low speed, sometimes without any warning light beforehand, and in several cases the engine fails to restart afterward. Turbocharger-related symptoms also come up across multiple reports, with owners describing loss of boost pressure and abnormal noises from the engine compartment. A smaller cluster of fuel system complaints includes reports of fuel tank leaks. The stalling issue appears in more than one scenario, including situations where the engine cuts out after being left running in park, which in at least one report led to the vehicle rolling without driver input. The engine stalling and no-restart pattern is the clearest recurring thread in this complaint set.

By System
The 2012 Ford F-550 has 3 recalls, all carrying fire risk: two involve oil leaking from a power take-off pressure switch onto the exhaust, and one involves a compressed natural gas fuel tank that can break free from the vehicle frame.
The power take-off issue affects trucks equipped with certain PTO assemblies, where the pressure switch can leak oil onto a thermal blanket wrapped around the exhaust. That oil-soaked blanket, exposed to exhaust heat, can ignite. The CNG fuel tank recall applies only to F-550 transit buses converted to run on compressed natural gas: the brackets holding the passenger-side fuel tank to the frame can crack and fail, allowing the tank to separate from the vehicle entirely. A tank breaking loose at speed creates a crash risk on its own, and a ruptured CNG tank adds a fire hazard on top of that.
