The 2018 GMC Sierra has 3 recalls, all centered on the same serious issue: defective side curtain airbag inflators that can deploy without a crash, sending fragments toward occupants.
The inflators on either the driver or passenger side, or both, can rupture spontaneously and propel debris into the cabin with no warning. One of these recalls is an expansion of an earlier filing, meaning the prior remedy did not fully resolve the issue and a broader population of vehicles is now included.
