Warning Light On problems of the 2011 Nissan Xterra

On March 3 we started our car and the passenger's airbag warning light came on showing there was a problem. The next day when we took our vehicle into the Nissan dealer for service, we were told that the airbag control module was malfunctioning and they would have to order one since none were in stock. We waited nearly a month and then contacted the Nissan corporation customer service. After several calls we were informed yesterday that there would not be a module available until the end of may. This means that the only automobile we have now has no airbag protection for the passengers. We have paid in advance for this part which cost $1414. 35!.
