Vehicles Affected: Approximately 1,490,000 model-year 2014-17 Chevrolet Silverado 1500, 2500 and 3500 pickup trucks manufactured between Sept. 30, 2013, and Aug. 15, 2016, and 565,000 model-year 2014-17 GMC Sierra 1500, 2500 and 3500 pickup trucks manufactured between Sept. 30, 2013, and Aug. 15, 2016. This recall affects a total of approximately 3.6 million GM vehicles.
The Problem: Software that controls airbag and seat belt pretensioner deployment could have a defect and may prevent the deployment of frontal airbags and pretensioners in certain pre-crash situations. This increases the risk of injury in a crash.
An accident involving a 2014 Chevrolet Silverado pickup in which the driver's front airbag did not deploy is what triggered the recall investigation.
The Fix: Dealers will update the software for free.
