UPDATE 1-GM recalls 42,408 Saturn Vues; fluid leak possible

(Adds reports of four minor fires)

DETROIT, Sept 19 (Reuters) - General Motors Corp GM.N is recalling about 42,408 Saturn Vue compact SUVs built from February to July due to a potential leak of power steering fluid that could cause a fire, it said on Friday.

GM said there were four reports of minor fires in the engine compartment due to fluid coming in contact with the exhaust system, but no reports of accidents or injuries.

The report covers a tube nut that could have loosened on a group of Saturn Vues from the 2008 and 2009 model years that are equipped with six-cylinder engines.

GM said dealers would inspect and tighten the nut and check the fluid level as needed. The recall is expected to begin Sept. 26, according to the National Highway Traffic Safety Administration. (Reporting by Soyoung Kim and David Bailey; Editing by Lisa Von Ahn)
