Recalls

Airbags Vehicle recall #15V666000 · 2015 · 395 vehicles
What's wrong: The affected vehicles have front seat-mounted side impact air bags whose inflator May rupture upon its deployment.
Why it matters: 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.…
The 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.
Exterior lights Vehicle recall #22V137000 · 2022 · 740,581 vehicles
What's wrong: A reflection caused by the headlight housings May illuminate areas above the vehicle and outside of the driver's view with excessively bright light. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "lamps, reflective devices, and associated equipment."
Why it matters: The bright reflection May cause a glare for other drivers, reducing their visibility and increasing the risk of a crash.
The fix: Dealers will install headlamp appliques, free of charge. Owner notification letters were mailed September 8, 2022.
Visibility (wipers, glass) Vehicle recall #22V165000 · 2022 · 681,509 vehicles
What's wrong: The ball joints in the windshield wiper module May corrode, causing one or both windshield wipers to fail.
Why it matters: Inoperative windshield wipers can reduce visibility in certain driving conditions, increasing the risk of a crash.
The fix: Dealers will inspect the wiper module, and repair or replace it as necessary, free of charge. Interim owner notification letters informing owners of the safety risk were mailed on April 21, 2022. Owner notification letters were mailed on October 25, 2022.
