On certain vehicles, due to improper assembly of the air bag inflator, which is used in the side air bag, the curtain shield air bag, and the knee air bag assembly, some inflators were produced with an insufficient amount of the heating agents necessary for proper air bag deployment. In this condition, the expansion force of the gas may be insufficient to properly inflate the air bag when the SRS system is activated during a crash.
Dealers will replace the specific SRS air bag. The recall began on April 6, 2006. Owners may contact Toyota at 1-888-270-9371, Scion at 1-866-548-1851, or Lexus at 1-800-255-3987.
