General Motors (GM) has announced a new safety recall affecting more than 40,000 Buick, Chevrolet, Cadillac, and GMC vehicles that may not have received a complete software update during the remedy process for a previous recall.

Without the proper update, certain driving conditions may cause the air bag sensing and diagnostic module (SDM) software on the affected vehicles to activate a diagnostic test. During this test, deployment of the frontal air bags and the seat belt pretensioners would not occur in the event of a crash.

A failure of the front air bags or seat belt pretensioners to deploy during a crash increases the risk of injury to the driver and front passenger.

Impacted Vehicles

The following vehicles are included in this recall: certain model year 2014-2016 Buick Lacrosse and Chevrolet Spark EV, Caprice PPV and SS vehicles; model year 2014-2017 Buick Encore and Chevrolet Corvette, Silverado 1500 and GMC Sierra 1500 vehicles; model year 2015-2016 Cadillac Escalade and Escalade ESV, Chevrolet Tahoe, Trax, Suburban and Silverado 2500 and 3500 and GMC Yukon and Yukon XL vehicles; and model year 2015-2017 GMC Sierra HD 2500 and 3500 vehicles.

What Happens next?

GM will notify owners of the recalled vehicles. Dealers will then reflash the SDM software. Vehicles that have had a previous air bag deployment will have the SDM replaced. These repairs will be performed free of charge.
