On certain vehicles, the sensing and diagnostic module (SDM), which controls airbag and pretensioner deployment, contains a software defect which may prevent the deployment of frontal airbags and pretensioners in certain circumstances. Failure of frontal airbags and seatbelt pretensioners to deploy in a crash (when warranted) could increase the risk of injury. Correction: Dealers will reflash the SDM with new software. 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. Note: This recall affects 2014-2017 model year Sierra LD/Silverado LD models and 2015-2016 model year Sierra HD/Silverado HD model vehicles.

On certain vehicles, an improper weld on the rear shock absorbers may lead to separation of the shock absorber tube from the shock absorber clevis bracket. If such a separation was to occur, a sudden change of vehicle handling behaviour would result that may startle drivers, increasing the risk of a crash causing injury and/or damage to property. Correction: Dealers will replace both rear shock absorbers.
