General Motors is recalling 316,357 vehicles in North America because their low-beam headlights can stop working. The recall affects the Buick LaCrosse sedan and the Chevrolet Trailblazer, GMC Envoy, Buick Rainier, Saab 9-7X and Isuzu Ascender SUVs. All of the vehicles are from the 2006 through 2009 model years. GM says the low-beam headlights or daytime running lamps could intermittently or permanently stop working. If that happens it increases the risk of a crash. The issue doesn’t affect the high-beam headlights, fog lamps or turn signals.
