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 or crash risk: CNG-converted transit buses may have brackets that break and allow the compressed natural gas tank to separate from the frame, and two separate recalls cover oil leaking from a power take-off pressure switch onto exhaust insulation where it can ignite.
The fuel tank separation on CNG-converted vehicles raises the risk of both a crash and a fire if the tank breaks free while driving. The oil leak issue appears across two recall filings from different equipment installers, but both describe the same scenario: oil from the power take-off pressure switch soaks into the thermal blanket wrapped around the exhaust, and the combination of oil and exhaust heat can start a fire. These PTO-related recalls apply to vehicles modified by specific upfitters, so not all F-550s from this era are affected.
