Other Fuel System Tank Filling/charging problems of the 2004 Buick Rendezvous

Recently the cabin is filling with the smell of gas fumes while at idle and filling at gas station. There is no service engine light coming on, indicating some sort of leak in the fuel entrance to the tank. There is a recall #06230 that directly relates to this, however I am told that my vehicle was made a little later and gm had determined the later produced vehicles did not have the problem that required the fuel tank to be replaced. I think this needs to be investigated further.
