WASHINGTON, Sept 9 (Reuters) - General Motors Co said on Friday it will recall nearly 4.3 million vehicles worldwide to fix a software defect that can prevent air bags from deploying during a crash, a flaw already linked to one death and three injuries. GM said the sensing and diagnostic module that controls airbag deployment has a software defect that may prevent the deployment of frontal airbags in certain "rare circumstances when a crash is preceded by a specific event impacting vehicle dynamics." The Detroit automaker said the recall of newer trucks, cars and SUVs from the 2014-2017 model years would not have a material impact on its financial results. The following models will be recalled; 2015-2017 Chevrolet Tahoe, Suburban and Silverado HD, GMC Yukon, Yukon XL and Sierra HD and Cadillac Escalade and Escalade ESV; 2014-2017 Buick Encore, GMC Sierra and Chevrolet Corvette, Trax, Caprice and Silverado; 2014-2016 Buick LaCrosse, Chevrolet SS and Spark EV. The U.S. National Highway Traffic Safety Administration (NHTSA) said in a notice posted on Friday that "certain driving conditions may cause the airbag sensing and diagnostic module software to activate a diagnostic test" that would prevent the airbag from deploying in the event of a crash. In July, GM said the NHTSA may force it to recall another 4.3 million vehicles for potentially defective Takata airbag inflators, a call-back that would cost the U.S. automaker $550 million.
