General Motors is adding 181,000 cars in the U.S. and Canada to a 2014 recall for headlights that can stop working.

The expansion covers the 2005 Buick LaCrosse, the 2007 Pontiac Grand Prix in the U.S., and the 2005 Buick Allure in Canada.
A headlight module may not work in high temperatures under the hood. That can cause the low-beam and daytime running lights to fail. Dealers will replace the module with an existing part until a permanent repair is developed and installed.
The 2014 recall affected 316,357 vehicles from 2006 through 2009 including the LaCrosse, Chevrolet Trailblazer, GMC Envoy, Buick Rainier, Saab 9-7X and Isuzu Ascender.
