I had a problem with my air bag light on the instrument panel staying on all the time. I went to my garage and they had to replace both the right and left side belts. My car only has 30,000 miles on it and it does not seem as if this should have occurred for this short time.

The airbag would not turn off and a buzzer would sound every half an hour with a series of five beeps five times. It cost me $750 to have the seat belt replaced. It would be nice if this was a recall, as that was a lot of money on social security.
