The 1978 Ford F-100 has 3 recalls, the most serious involving the steel wheels on certain trucks, where tooling marks in the rim can cause the bead seat to split at high mileage and rapidly deflate the tire, similar to a blowout.
On 4x4 models, the driver-side upper shoulder belt retractor bracket was incorrectly modified during assembly and may not hold under the forces of a crash, meaning the belt could fail to restrain the driver at the moment it is most needed. There is also an emissions-related concern: the evaporative emission purge valve on some trucks may be disconnected, allowing a small amount of fuel vapor to escape into the atmosphere rather than being routed back through the engine.
