Side/window Air Bag problems of the 2004 Lexus ES

Vehicle was parked overnight in garage. Though not noticed immediately, sometime during the morning I noticed my dashboard vinyl around the passenger side airbag looked swollen , and upon examination, it showed a split in the vinyl also. I took it to a reputable auto repair shop and was told it would cost thousands to fix, but that a dealership might be able to help. So I went to the local Toyota deal who said some vehicles had recalls but mine did not. As time goes on, the vinyl seems to have pressure building behind it, and the split is more obvious. I am afraid to allow passengers to sit in that seat. I am afraid if the airbag burst out while I am driving, I may overreact and wreck. This is not safe at all. Please help.

There is a crack on the passenger side airbag of my car. It is protruding around the area of the airbag. I took my car to the Lexus dealership on July 14, 2014, for this problem. Only to be told that I would need to replace my dash board and it would cost me over 2,500 dollar. I have never experience anything like this before ever. This is truly a very stressful and uncertainty wondering everytime I get into my car, afraid and hoping that the airbag does not exploded. Based on the recall of my car model, make I need to be contacted on the next action that needs to be taken. I would appreciate your response back. Thank you kindly.
