Paint problems of the 1999 Chevrolet Malibu

I have a 1999 chevy Malibu. I noticed last year about August around my gas tank the paint was starting to bubble, so I took it in to a chevy dealer in livonia to see if there was a warranty on the bubbling paint, they had told me the warrant was up on that, they had also said that they had been getting a lot of complaints about the same issue from other owners of a 1999 chevy Malibu. I wanted to know if general motors is going to have a recall on that, or do I just have the problem fixed by a body shop?.
