I purchased a used mazda 2008 cx-7 almost a yr ago. I was just driving home from work and the air bag sign came on my dash, blinked at first but then stayed there. I also purchased the extended warrenty but to only find out that the something screen which is right behind the steering column is the only thing covered. Has anyone else had this problem? If so what did you do besides taking it to a dealership and paying over $100 for them to look at the light and say something is wrong. Help me please
