The 2021 Ford F-750 has 3 recalls, with two of them posing a fire risk: a transmission fluid leak on gas-engine models and a fuel leak on diesel-engine models can both expose flammable fluid to ignition sources in the engine compartment.
Both fire-related recalls are engine-specific. On trucks with the 7.3L gas engine, a transmission oil cooler line can rub against the air conditioning compressor pulley until it wears through, allowing transmission fluid to drip onto hot engine components. On trucks with the 6.7L diesel engine, a small void in the secondary fuel filter cap can gradually open into a pinhole, letting diesel fuel seep out from the top of the filter housing where it can contact a heat source or spark. The third recall also affects diesel-equipped trucks: biodiesel deposits can build up on the internal components of the high-pressure fuel pump, eventually causing the pump to fail and cutting power to the engine while the truck is moving.
