One problem related to tank assembly has been reported for the 2001 Saturn SC2. The most recently reported issues are listed below.
It is a concern to me that my gas bangs around in tank and I hear it. It is so loud of a hi t at times that I think I have hit something. It is most noticable between 3/4 and 1/2 full. I have never been in a car that you hear the gas in it like this. Saturn told me this is how it is.
