Defective airbag recall. Remember, this recall repair must be performed by the manufacturer through the dealerships.
You can call your local dealership, give them your VIN number (vehicle identification number) and they can advise you if your car is subject to recall. The VIN number is located at the driver's side lower corner of the windshield, there is also a sticker on the inside door jam of driver's door. If all else fails, you can read it off of your vehicle's registration.
Another note, it is always a good idea to make sure your car is as safe as it can be. Check out safercar.gov and type in your year, make and model to see if your car has any additional recalls.
