I hit a bump and the light came on. The scan tool (which the dealer charged me $100 to use) said it was a ground fault in the passenger side seat sensor (that tells the computer whether there is someone sitting in the passenger seat.) I still haven't got around to getting it fixed. The dealer said that the sensor's only purpose was to tell the computer not to set off the passenger air bag, so now it will go off if the driver's side one goes off, whether or not someone is sitting in the passenger seat. I can live with that, rather than pay the dealer the $1500 plus he wanted to charge me to fix it.
Why should you have to pay to have a faulty airbag system serviced if your car was never involved in a collision and is still under warranty?
I don't think my car is still under warranty.
By the way you can buy the extended warranty after your original warranty expires as long as certain conditions are met. I'm just not sure what those conditions are.
