The 2016 GMC Sierra has 4 recalls, the most serious involving the airbag control module, which can develop a cracked housing that allows water in and causes the airbags to fail or misfire in a crash.
The remaining three recalls fall into electrical and compliance categories. The radio on certain trucks can intermittently stop producing the audio chime that warns the driver when a key is left in the ignition or when a seatbelt goes unfastened. A driver who misses that reminder and stays unbelted faces a higher risk of injury in a crash. There is also a compliance recall tied to federal standards covering theft protection, rollaway prevention, and occupant protection in frontal impacts, though the specific functional consequence is not detailed in the filing.
