According to Ford, a fuel injector may crack and leak fuel inside the engine compartment, leading to an under-hood fire.

The automaker says the fuel injectors inside the recalled vehicles could crack and leak inside the engine compartment. If enough liquid fuel or even fuel vapor accumulates on a hot surface, a fire could ignite underneath the hood.

Ford Motor Co. is recalling almost 700,000 vehicles to address a long-running issue over cracking in an auto part that can leak fuel into the engine and cause fires.
