General Motors is recalling certain model year 2005 Buick LaCrosse vehicles manufactured May 31, 2004, to June 27, 2005, and 2007 Pontiac Grand Prix vehicles manufactured April 12, 2006, to April 25, 2007. In the affected vehicles, the headlamp driver module (HDM) may overheat and fail, causing the headlamps and daytime running lights to not illuminate.
Headlamps that do not illuminate reduce the driver’s ability to see the roadway and reduce the vehicle’s visibility to oncoming vehicles, both of which increase the risk of a vehicle crash.
Approximately 159,584 vehicles are affected by the recall.
GM will notify owners, and dealers will replace the HDM, free of charge. Interim notices will be mailed to owners on September 2, 2015. Owners will receive a second notice when remedy parts are available.
