2 of my 2005 Grand Marquis' seat belt buckles have failed.
air bag light on. ford replaced driver side seat belt and then the light came on again and ford said the passenger side seat belt also had to be replaced. I refused the repair and since the seat belt works ok will forget about the air bag if it depends on a buckle spring. Have driven for over 70 years and have never had a head on collision. Have only a few more years left to drive.

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.

Airbag light on with beeping. I haven't fixed problem as the dealer wants to replace both seatbelts at 1200 dollars. I am on fixed income and not happy with this problem

Airbag light stays on. Flashes code 33 indicating a problem in the seat belts. This problem was verified by Kinsel Ford Dealership in Beaumont, Texas. Cost $132.00 for report. Not fixed yet.I expect Ford to repair this problem at no cost to me.
