What Happened
The air bag sensing and diagnostic module (SDM) in your vehicle is a computer that helps decide when to deploy the front air bags and seat belt pretensioners in a crash. In some 2014-2017 models, this module might not have gotten the complete software update needed to work correctly.
Risk if Unfixed
If you're in a crash that needs front air bag deployment, and your SDM isn't working right, the air bags and seat belt pretensioners won't work as they should. This could lead to serious injury to you or a passenger.
Free Fix
Your dealer will update the SDM software to fix the issue. If your air bags have already deployed, they'll replace the SDM entirely – both repairs are free. You should schedule the fix as soon as you get the recall notice.

Original — What Happened
General Motors LLC (GM) is recalling certain model year 2014-2016 Buick Lacrosse and Chevrolet Spark EV, Caprice PPV and SS vehicles, 2014-2017 Buick Encore and Chevrolet Corvette, Silverado 1500 and GMC Sierra 1500 vehicles, 2015-2016 Cadillac Escalade and Escalade ESV, Chevrolet Tahoe, Trax, Suburban and Silverado 2500 and 3500 and GMC Yukon and Yukon XL vehicles, and 2015-2017 GMC Sierra HD 2500 and 3500 vehicles. While being previously remedied for recall 16V-651, the affected vehicles may not have received the complete software update necessary to remedy the recall condition. Without the update, certain driving conditions may cause the air bag sensing and diagnostic module (SDM) software 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.
Original — Risk if Unfixed
A failure of the front air bags 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.
