Air bags: Frontal: Sensor/control module-inactive and 2 more components
NHTSA 17V437000Reported Jul 10, 2017
Filed by
General Motors, LLC (manufacturer recall no. 17287)
Components
Air bags: Frontal: Sensor/control module-inactive; Air bags: Frontal; Seat belts: Pretensioner
Units affected
40,683 (estimate)
Problem
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.
Risk
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.
Remedy
GM will notify owners, and dealers will 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. The recall began on August 4, 2017. Owners may contact Buick customer service at 1-800-521-7300, Cadillac customer service at 1-800-458-8006, Chevrolet customer service at 1-800-222-1020, or GMC customer service at 1-800-462-8782. GM's number for this recall is 17287.

Units affected
395 (estimate)
Problem
General Motors LLC (GM) is recalling certain model year 2015 Buick LaCrosse, Cadillac XTS, Chevrolet Camaro, Equinox, Malibu, and GMC Terrain vehicles. The affected vehicles have front seat-mounted side impact air bags whose inflator may rupture upon its deployment.
Risk

The rupture could cause metal fragments to strike the vehicle occupants, potentially resulting in serious injury or death. Additionally, if the air bag does not properly inflate, the driver or passenger is at an increased risk of injury.
Remedy
GM will notify owners, and dealers will replace the side impact air bag modules, free of charge. The recall began on October 19, 2015. Owners may contact Buick customer service at 1-800-521-7300, Chevrolet customer service at 1-800-222-1020, Cadillac customer service at 1-800-458-8006, or GMC customer service at 1-800-462-8782.
