I purchased a 2003 Santa Fe lx 4wd with the 2. 7l engine. Almost from the time I purchased the vehicle, it has been suffering from a sulfur smell. The dealer made one repair that seemed to last for about a week, unfortunately, the odour is back. The dealer claims that they cannot duplicate this concern, however, they only drive the vehicle 2 or 3 miles when I take it to them to be serviced. Funny how everyone except the dealer can smell this foul disgusting odor.
