General Motors is recalling 4.3 million vehicles around the globe, including 2015-2017 Chevrolet Silverado and GMC Sierra trucks, over concerns of possible air bag deployment failure.
GM reports that certain driving conditions may cause the air bag sensing and diagnostic module software to activate a diagnostic test during which the front air bags and seat belt pretensioners will become disabled and non-functional in the event of a crash.
A failure of the front air bags or seat belt pretensioners to deploy in the event of a crash increases the risk of injury to the driver and front passenger.
Chevrolet 2015-2017 Silverado 1500, 2500 HD and 3500 HD as well as 2015-2017 GMC Sierra 1500, 2500 HD and 3500 HD are being recalled due to the defect. Also being recalled are 2015-2017 Chevrolet Tahoe and Suburban; GMC Yukon and GMC Yukon XL; Cadillac Escalade and Cadillac Escalade ESV; 2014-2017 Chevrolet Corvette, Trax, Caprice Police Pursuit Vehicle and Buick Encore; 2014-2016 Buick Lacrosse, Chevrolet Spark EV and SS vehicles.
GM will notify owners and dealers will reflash the SDM software to remedy the defect. Vehicles that have had a previous air bag deployment will have the SDM replaced. These repairs will be performed free of charge.
