Ford is recalling over 850,000 vehicles due to a potential low-pressure fuel pump failure, according to the National Highway Traffic Safety Administration, NHTSA.

The NHTSA estimates that ~10% of the recalled vehicles have this specific defect. Before a fuel pump failure occurs, drivers might observe symptoms such as poor engine performance, such as misfiring, rough running, reduced power, or the illumination of the check engine light.

Ford advises that drivers may experience poor engine performance (misfiring or running rough), a check-engine light, or a reduction in engine power before the pump fails. The fuel-pump failure is more likely to occur in low fuel or warm weather and hot fuel conditions in the fuel tank.
