The 2008 GMC Sierra 3500 has 3 recalls, the most serious being a passenger-side airbag inflator that can rupture in a crash and send metal fragments into the cabin, posing a risk of serious injury or death.
This airbag concern spans two related issues: the original inflator is defective, and in some cases where an interim replacement part was installed as part of an earlier repair attempt, that replacement inflator carries the same rupture risk, meaning prior repair attempts did not fully resolve the problem. The third recall involves vehicles equipped with an auxiliary battery, where a fusible link in the electrical system can melt and contact nearby wiring and components, raising the risk of fire.
