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

Dearborn, Michigan-based Ford has issue 89 recalls with the NHTSA so far this year, impacting more than 5 million vehicles, according to the federal agency's recall records. The latest fuel pump-related recall follows a similar recall in January, involving 295,449 diesel-engine trucks with high-pressure fuel pumps.

A remedy is not yet available, either. Ford says owners of these models will be notified when a fix is ready. Notably, the majority of the 850,000 units included in the recall are Broncos (109,881) and Ford F-150s (455,261) In any event, this recall further suggests that Ford dealerships will be busy with recall work for some time to come.
