GM recalling vehicles
DETROIT — GM is voluntarily recalling about 3.64 million 2014-17 model year vehicles in the U.S.
The sensing and diagnostic module, SDM, in these vehicles, which controls airbag and pretensioners deployment, contains a software defect that may prevent the deployment of frontal airbags and pretensioners in certain rare circumstances when a crash is preceded by a specific event impacting vehicle dynamics.
The recall includes certain:
• 2014-2016 model year Buick LaCrosse and Chevrolet SS and Spark EV
• 2014-2017 model year Chevrolet Corvette, Trax, Caprice PPV and Silverado 1500; Buick Encore; and GMC Sierra 1500
• 2015-2017 model year Chevrolet Tahoe, Suburban and Silverado HD; GMC Yukon, Yukon XL and Sierra HD; and Cadillac Escalade and Escalade ESV.
GM will notify customers, and dealers will update the software free of charge.
