Ford has issued a recall for approximately 7,500 examples of the 2018 Ford Expedition and F-150, as well as the 2018 Lincoln Navigator. All affected vehicles are equipped with Ford's 3.5-liter EcoBoost V6.

The issue stems from the high-pressure fuel pump. Evidently, welds between the pump housing and the mounting flange might not be adequate and could be susceptible to fatigue fractures. If that happens, the fuel pump could move and cause either a fuel or oil leak, which can lead to a fire in the right circumstances.
