	In a letter dated august 27, 2008, general motors corp. (gm) notified nhtsa that it will conduct a safety recall (nhtsa recall number 08v-441) to address a safety relateddefect that can result in engine compartment fire in approximately 850,000 vehicles equipped with a heated windshield washer fluid option.the subject vehicles of this investigation comprise over three-quarters of the recall population. according to gm, a short circuit on the printed circuit board for the windshield washer fluid heater module may overheat the control-circuit ground wire. this may cause other electrical features to malfunction, create an odor or cause smoke and in rare cases it may cause a fire.as a remedy, gm dealers will install a wire harness with an in-line fuse. in addition to the subject vehicles, several other gm models with the heated windshield washer fluid option are included in recall 08v-441: my 2006-2008 buick lucerne (manufactured august 2005 through november 2007); my 2008 buick enclave (manufactured february 2007 through april 2007); my 2006-2008 cadillac dts (manufactured may 2007 through november 2007); my 2007-2008 saturn outlook (manufactured august 2006 through april 2007); and my 2007-2008 gmc acadia (manufactured august 2006 through april 2007) vehicles.gm is instructing owners to take their vehicle to a dealer for service if they experience symptoms of windshield washer heater module short circuits. gm's recall resolves the safety defect concerns pursued by this investigation.this engineering analysis is closed.
