I have a 2003 rodeo with 1200 mi on it. From day 1 I could smell the dreaded rotten egg smell associated with a bad converter. Dealer rep advised putting on a few more miles. Did that. After a while checked fuel economy. In the toilet at 12/16 Again dealer says needs more break-in time. Then noticed muffler looking very blue like it was getting too hot. Son looked under and says converter burnt looking . Going back in tomorrow for service. Anyone else having converter problems on a new vehicle?Sue, a sulpher/rotten egg smell is not the symtoms of a bad cat. It's usually the result of a rich running engine, or the quality of the gasoline being used. 12-16mpg is pretty typical for a brand-new 3.2L in mixed city/hwy driving. MPG's will get better after 3-5Kmi or so. My 2002 rodeo will give off some stink when driven hard. Depends on the brand of gasoline used. I have the best luck with sunoco gasoline. These are fairly thirsty, heavy breathing, somewhat rich running engines. I guess thats how they get 205hp out of a small 3.2L engine. @ 16Kmi, my 2002 will get 15mpg mixed diving & 20 hywy. The sulpher smell will fade as the engine breaks in. Try some different brands of gasoline to see if that helps. You would get a check engine light & SEVERE performance issues if either of your (2) cats were bad. G/luck
