Component
AIR BAGS:FRONTAL
Manufacturer
General Motors LLC
What Happened
The air bag sensing and diagnostic module in your vehicle helps determine if the front air bags should deploy in a crash. In certain models from 2014-2017, this module might not have received a full software update, which could cause the air bags to fail to deploy in a crash.
Risk if Unfixed
If the air bags or seat belt pretensioners don't deploy when they should, you and your front passenger could be at risk of serious injury in a collision.
Free Fix
Your dealer will update the software in your air bag sensing and diagnostic module, and if you've had a previous air bag deployment, they'll replace the module entirely – all free of charge. You should schedule the repair as soon as you receive 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.
