Why does the Kia Sorento sometimes emit sulfuric o r rotten‑egg smells, and what emission system components are typically at fault?

Several Sorento owners have reported unusual exhaust odors—like sulfur o r rotten‑egg smells—often accompanied by diminished performance o r the illumination of the check engine light. Could these symptoms indicate problems with the catalytic converter, oxygen sensors O₂ sensors, o r other emission control components like EGR valves? Have local mechanics in Pakistan identified common causes e.g., failing O₂ sensors, clogged converters, exhaust leaks? What signs did owners observe, and how were these issues diagnosed o r resolved—through sensor replacement, exhaust system repairs, o r full catalytic converter overhauls?
