Ford has not yet released a remedy for the issue. Impacted owners will receive letters alerting them to the problem starting July 14.

Ford Motor is recalling 850,318 vehicles in the U.S. due to a potential low-pressure fuel pump failure, which could cause an engine stall, the U.S. National Highway Traffic Safety Administration said on Thursday.

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.
