Safety

GM is aggressive in promoting the benefits of OnStar 8.0. New-truck buyers get a one-year subscription to the Safe and Sound Plan, after which owners can subscribe annually. If an airbag deploys, OnStar contacts an adviser and can report crash data to emergency services. The Sierra offers roof-mounted side curtain airbags as standard equipment on all trim levels. Seat-mounted side-impact airbags are also standard. An electronic stability system is now standard on all Sierra models.
