General Motors recalls Buick LaCrosse and Pontiac Grand Prix vehicles

General Motors is recalling 159,584 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.

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.

GM will notify owners, and dealers will replace the HDM, free of charge. Interim notices were scheduled to be mailed to owners on September 2, 2015. Owners will receive a second notice when remedy parts are available.

Owners may contact Buick customer service at 1-800-521-7300 or Pontiac customer service at 1-800-762-2737. GM's number for this recall is 14291.
