In an auto collision where a car rear end the vehicle from an idle position into an 18-foot box truck in front which was also idle. The vehicle smashed in the front and back which it was deemed a total loss and the airbag did not deploy. This caused the driver to have several injuries including a head concussion. When contacted the dealer service department where recall maintenance had been performed, I was instructed to contact the airbag manufacturer. The vehicle inspected by insurance adjuster (GEICO). There were no warning lamps or messages prior to the failure of the airbag deploy.
