General Motors is expanding its headlight recall to the Buick LaCrosse and Pontiac Grand Prix.
The defect: in affected vehicles, the headlamp driver module (HDM) may overheat and fail, causing the headlamps and daytime running lights to not illuminate.
The hazards: driver visibility can be significantly reduced in the event of losing low-beam headlights, increasing risk of an accident especially during times of low visibility such as night-time, rain, or fog.
GM knows of no confirmed crashes or injuries related to the issue.
Affected vehicles: in November 2014, GM recalled 316,000 units of the following vehicles:
- 2006-2009 Buick LaCrosse
- 2006-2007 Chevrolet Trailblazer
- 2006-2007 GMC Envoy
- 2006-2007 Buick Rainier
- 2006 Trailblazer EXT
- 2006 GMC Envoy XL
- 2006-2008 Saab 9-7X
- 2006-2008 Isuzu Ascender
The expanded recall includes:
- 2007 Pontiac Grand Prix manufactured May 31, 2004 through June 27, 2005
- 2005 Buick LaCrosse (at the time of this model the LaCrosse was called Buick Allure in Canada) manufactured April 12, 2006 to April 25, 2007
Number of vehicles affected: 180,504 units, of which:
- 159,584 were sold in the United States
- 21,000 were sold in Canada (including Buick Allure)
The fix: GM has yet to announce a permanent repair. Until a permanent solution is available, dealers will replace the headlamp module with a new one of the existing part.
Roughly two months after the November 2015 announcement of the original recall, GM told owners that it would have to replace the faulty headlamp module with a revised one at a future date.

Notes: the expansion of the recall came about when the National Highway Traffic Safety Administration informed GM on June 26th about complaints of headlight failures in LaCrosse, Grand Prix, and Trailblazer vehicles. In July, the automaker conducted additional analysis of its data and post-warranty repair information for 2005-2009 LaCrosse and 2006-2008 Grand Prix vehicles. This prompted the expansion of the recall.
In April, NHTSA certified that Delphi Corporation — the supplier of the headlamp module — did not supply the defective part to any other automaker.
