CHEVROLET recall on SILVERADO HD, SIERRA HD and 10 more models

Long-term exposure to high absolute humidity and temperature, combined with high temperature cycling, may eventually degrade the propellant contained in the passenger-front airbag. This could cause the airbag to deploy with more force than normal. If the airbag inflator ruptures, fragments could be propelled toward vehicle occupants or cause damage to the airbag assembly, preventing its proper function.

If the vehicle is involved in a crash requiring an airbag deployment, the airbag inflator could rupture and create a risk of injury.

General Motors will notify owners by mail and instruct you to take your vehicle to a dealer to replace the passenger-front airbag.
