Around 3:00 PM today, General Motors announced a safety recall affecting 3.6 million vehicles involving the non-deployment of the frontal air bag and pretensioner. Select C7 Corvettes from 2014 to the present are affected by this recall.
General Motors has decided that a defect which relates to motor vehicle safety exists in certain 2014-2017 model year Chevrolet Silverado LD, GMC Sierra LD, Buick Encore, Chevrolet Trax, Chevrolet Caprice Police, and Chevrolet Corvette vehicles, 2014-2016 model year Buick Lacrosse, Chevrolet Spark EV, and Chevrolet SS vehicles and 2015-2017 model year Chevrolet Silverado HD, GMC Sierra HD, GMC Yukon, GMC Yukon XL, Cadillac Escalade Cadillac Escalade ESV, Chevrolet Suburban, and Chevrolet Tahoe vehicles. The sensing and diagnostic module (SDM) in these vehicles, which controls airbag and pretensioner deployment, contains a software defect which may prevent the deployment of frontal airbags and pretensioners in certain rare circumstances. If the frontal airbags and seatbelt pretensioners do not deploy when required, there is an increased risk of injury to occupants in a crash.
Reprogram the SDM with new software that eliminates this defect. In vehicles with any previous deployment events recorded in the SDM, the dealers will replace the existing SDM with a new SDM containing the latest software.
