General Motors is recalling 40,683 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.
While being previously remedied, the 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 front airbags and the seat belt pretensioners would not occur in the event of a crash.
Failure of the front airbags or seat belt pretensioners to deploy in the event of a crash increases the risk of injury to the driver and front passenger.
What to do
GM will notify owners, and dealers will reflash the SDM software. Vehicles that have had a previous airbag deployment will have the SDM replaced. These repairs will be performed free of charge. The manufacturer has not yet provided a notification schedule.
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 1728
