General Motors is recalling 42,408 of its 2008 and 2009 Saturn Vue crossovers because power steering fluid could leak onto the exhaust system sparking a vehicle fire.

The National Highway Traffic Safety Administration reported on its Web site that "some of these vehicles have a condition in which the nut securing the power steering line to the power steering pump may loosen."

The safety agency warned that as a result, fluid could leak from the power steering system and "contact hot exhaust components resulting in a possible engine compartment fire."

Saturn dealers will inspect the steering system and if there are indications of a fluid leak a technician will tighten the nut attaching the hydraulic line to the power steering pump and replace any lost fluid.

The recall is scheduled to begin September 26. Saturn Vue owners can contact General Motors at 1-800-972-8876.
