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?
