The 2021 Ford F-750 has 3 recalls, with two separate fire risks: a transmission fluid line that can rub against the A/C compressor pulley and leak onto hot engine components on 7.3L gas models, and a fuel filter cap that can develop a pinhole and leak diesel fuel near ignition sources on 6.7L diesel models.
The third recall also affects diesel-equipped trucks, where biodiesel deposits can build up on internal components of the high-pressure fuel pump and cause it to fail, cutting drive power unexpectedly and raising the risk of a crash.
