Airbag Defect Prompts GM to Recall More Than 3.6 Million Vehicles
the frontal airbags on the affected vehicles may not deploy
General Motors (GM) is recalling more than 3.6 million model year 2015-2017 Chevrolet Silverado 2500 HD, 3500 HD, Tahoe, Suburban, GMC Sierra 2500 HD and 3500 HD, GMC Yukon, GMC Yukon XL, Cadillac Escalade and Cadillac Escalade ESV vehicles; model year 2014-2017 Chevrolet Corvette, Silverado 1500, Trax, Caprice Police Pursuit Vehicle, GMC Sierra 1500, Buick Encore; and model year 2014-2016 Buick Lacrosse, Chevrolet Spark EV and SS vehicles.
In the affected vehicles, certain driving conditions may cause the airbag sensing and diagnostic module (SDM) software to activate a diagnostic test. During this test, deployment of the frontal airbags and the seat belt pretensioners would not occur in the event of a crash.
A failure of the front airbags or seat belt pretensioners to deploy in the event of a crash necessitating deployment increases the risk of injury to the driver and front passenger.
GM will notify owners of the recalled vehicles, and dealers will reflash the SDM software. Vehicles that have had a previous airbag deployment will have the SDM replaced. These repairs will be performed free of charge.
The manufacturer has not yet provided a notification schedule for this recall.
