My air bag sensor has stayed lit for several weeks. I have an appointment to have it looked at but in reading comments on other forums, seems this is a problem with Hyundai models and to fix it seems to be expensive. If the sensor light is on, does it mean the air bag won’t function? ---

If the air bad warning light is on the airbags will not function in the event of a crash. Don’t assume the cost of repair will be high until you find out why the light is on. ---

Thank you. It was diagnosed as needing a new seat belt for a cost of $400.
