Side/window Air Bag problems of the 2005 Mercedes Benz CLK320

Srs light appeared and we took vehicle into dealership and were told the passenger side airbag was defective and had to be replaced. We had the repair done on 10/03/14. We thought the manufacturer should be responsible for this safety issue since the vehicle is less than 10 years old. The dealership said it was not and the repair charges were paid by us. Wondering if this vehicle should be included in the national recall for defective airbags.
