General Motors is recalling approximately 3.64 million 2014- to 2017-model-year vehicles in the U.S. because a software defect in their sensing and diagnostic modules may result in air bag malfunction, the automaker said.
The recall includes certain:
- 2014- to 2016-MY Buick LaCrosse, Spark EV and Chevrolet SS vehicles
- 2014- to 2017-MY Chevrolet Corvette, Trax, Caprice PPV, and Silverado 1500; Buick Encore; and GMC Sierra 1500 vehicles
- 2015- to 2017-MY Chevrolet Tahoe, Suburban, and Silverado HD; GMC Yukon, Yukon XL, and Sierra HD; and Cadillac Escalade ESV and Escalade vehicles.
The sensing and diagnostic module controls air bag and pretensioners deployment. The software defect may prevent the deployment of frontal air bags and pretensioners in “certain rare circumstances when a crash is preceded by a specific event impacting vehicle dynamics,” GM said in a released statement.
Dealers will update the software, free of charge, to resolve the problem. To learn whether any of your vehicles are involved, fleet managers can click here to search by VIN.
