Recalls (3)
General Motors LLC (GM) is recalling certain model year 2015 Buick LaCrosse, Cadillac XTS, Chevrolet Camaro, Equinox, Malibu, and GMC Terrain vehicles. The affected vehicles have front seat-mounted side impact air bags whose inflator may rupture upon its deployment.
Risk: In the event of a crash necessitating deployment of one or both of the side impact air bags, the air bag's inflator may rupture and the air bag may not properly inflate. The rupture could cause metal fragments to strike the vehicle occupants, potentially resulting in serious injury or death. Additionally, if the air bag does not properly inflate, the driver or passenger is at an increased risk of injury.
Fix: GM will notify owners, and dealers will replace the side impact air bag modules, free of charge. The recall began on October 19, 2015. Owners may contact Buick customer service at 1-800-521-7300, Chevrolet customer service at 1-800-222-1020, Cadillac customer service at 1-800-458-8006, or GMC customer service at 1-800-462-8782.
