2007 HYUNDAI ELANTRA User Comment / Complaint

Dear representative i purchased the 2007 hyundai elantra gs for my son in december due to it's market safety ratings. i was ensured by the sales teams and reports that this car was safe. this morning my son was in a bad accident, and the airbags did not deploy. the car rear side window was crushed, the top of car was pushed inward and pinned under a pipe fence, the driver side where the gas tank was located was smashed to the point that components melted together. also, there was major damage to the tires/rim, side ,and front of the car. bumpers in the front and back were dislodged and shredded in some areas. this was not acceptable to sell cars that air bags did not deploy with the amount of damage sustained. i wish to file an official complaint against hyundai. i would like to know what outside organization's could i register the complaint with. hyundai could have cost my son his life to make a quick buck.
