Airbag light on instrument panel stayed on constantly. Read forums on the internet and found that the bulb in the dash for the passenger airbag light had blown, replaced bulb, airbag light on instrument panel went out. $6 fix!!!

This is the second time my car has had this problem in the last two years. When it airbag warning light illuminated stayed on, i took it to the madza dealer and they told me it was warranted and repaired it at no charge. They found that the spring had slipped off sensor. Now again the light has came on and i do not understand how a safety feature came just malfunction so easily without any damage to it and i fear that the bag may open on me. I no longer had any warranty on my car and feel that with a safety issue like this it should not malfunction without a cause and should have to be covered at no charge even after the car warranty has expired.
