GENERAL MOTORS issued a recall on the SIERRA, and SILVERADO models

Certain vehicles may fail to conform to Canada Motor Vehicle Safety Standard (CMVSS) 114 - Theft Protection and Rollaway Protection, and CMVSS 208 - Occupant Protection In Frontal Impacts. The radio software may intermittently fail to provide an audio warning when a key is left in the ignition and the driver door is opened, or when the driver forgets to put on their seat belt, which is contrary to the requirements of the standard. A loss of the seat belt audible warning may increase the likelihood of a front outboard occupant being unbelted, increasing the risk of injury in a crash. Similarly, the loss of an audible warning when a key is left in the ignition may increase the risk of vehicle theft. Correction: Dealers will reflash the radios with corrected software.
