Takata recall. After taking my car in to the Acura of orange park FL to have airbag system checked related to the recall the repair was made and a week later the indicator light came on again. I called the dealership to advise and was told to bring it back which I did and was told the recall repair was made. However, the switch is faulty and needed to be replaced for a cost. I then called the corporate office and was told to return it at which time I was told that isn't covered in the recall. Now I don't know if the airbag system indicator is accurate or not because the light comes on and off daily as I drive.
