This investigation was opened on Jun. 12, 2008.
It was closed on Sep. 8, 2008.
Note: this investigation has resulted in
a vehicle safety recall. 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. |
