When I bought my Santa Fe in 2003 (please don't hate on me), it used to smell like rotten eggs almost every day. After some heated discussions with the service manager, I was finally convinced that it was the additives in the gasoline (especially during the Cleveland winters). Once I tried different brands, the smell would be gone with some, but not others. It never threw a code, so I just learned to live with it.
The smell finally went away, but still comes and goes, depending on the gasoline used.
