|On certain vehicles, the inflator diffuser installed in certain side curtain air bag modules may not have been manufactured correctly. If the vehicle were involved in a crash that warranted side curtain airbag deployment, this could potentially lead to the diffuser detaching. If the diffuser were to detach, it could become a projectile in the occupant compartment, and could cause a tear that could result in the side curtain airbag to not fully inflate. Both of these conditions could increase the risk of injury in a crash. Correction: Dealers will replace both the right and left hand side curtain airbags.
