So I have a question:
Why did this issue essentially stop for me when I started using premium gas? My smell was definitely the "exhaust/sulfur" smell - others report something different. I had the smell for the first couple of weeks I had my Sport, and then I switched to premium fuel and I haven't noticed it since
I came out of a long line of performance sedans, and I don't cut my Sport any slack. I drive it hard on a regular basis. Yesterday I happened to come across a long, empty freeway entrance ramp with no merge traffic and lets just say I took FULL advantage of it
No stink.....
I have NEVER had my climate control set to recirculate the air; from day one it has always been set to "fresh". Yet... I had the smell, and then I didn't, and the only thing that changed was the switch to 92+ octane gas.
It's just very bizarre.
The only other thing I noticed was that at one point I replaced the hitch cover - I had it off for a while but then put it back on, and I can't remember when I did that or if there is any correlation, but regardless, it's all very strange.
Just putting this out here for a data point. I'm happy that, at least for now, I no longer have the cabin smell issue, but I really wish I knew WHY....
