The title say it all, my car,08 IS250 RWD, now is having that issue. Like when im driving, it constantly came out from no where. Sometimes when i turn on the air condition or when i roll down the window. I don't know where the hell it is causing the problem? Does anyone has the same issue before? I check the cabin filter fine as new. Last time i changed the spark plug with my buddies but i did torque every bolts properly. Is it possible from the fuel line leaking? I checked it but no leaks at all. Any help/opinion would be a apappreciation, that sulfur smell is getting me very annoying. I don't want people think i ate onions and farted.

Thanks

 

This has a pretty thorough answer, though I don't know how accurate it is: http://wiki.answers.com/Q/How_can_yo...nverter_is_bad

 

That's actually make a lot of sense. Thanks buddy ill check it when i get to the shop. Will be update on than as well.

 

I know that this is a common issue with cats in the V8 4runners, but never heard of it happening in the IS...

 

I know right? I mean drive normal as always. Sigh, do u think this could be done under power train warranty or not? Or CPO warranty?

 

Happen to me to thought was the AC so had AC vents cleaned and filter changed by lexus and still yet smell it but as time went by it desipated nomore smelly egg rotten lasted about 3months

 

I just went to dealership and they told me if there's no check engine light on, they can not replace it for me. Its cover under certified warranty. Dang but the smell is getting me very annoying.

 

Hows the battery look? Lots of corrosion? Age? I'm about 97% certain batteries have sulfuric acid in em.. and its probably leaking out.

 

Battery is good. It died two times due to leave the lights on and I jump started it. The age of the battery you mean? Not sure, I bought this car a year ago and battery came with it. Corrosion? I don't think so.

 

did the dealer smell the odor and not give you a reason?

 

So if it died twice and jumped back to life theres a good chance that the chemicals inside the battery is going bad. yeah it may crank fine now, but if it hasnt been replaced since it died i would say replace the battery and see if the smell goes away. batteries do have that rotten egg smell when going bad.

 

He was my favorite service adviser, but he told me in the office without even get to my car.

Hmmm, Godd point!! I'll change it and see what happen! Thanks alot and I'll keep you post on this.

 

Hey! Its the battery! I drove it for a while come back home and head down to smell it... EWWW！！ god damn. Thanks bro. Without u i cant find out what happen.

 

Wow, I would have guessed its the cat myself. I know batteries can put out gases when charging, but surprised it was an amount that is noticeable seeing how ventilated it is (vs a closed space like a trunk).

 

glad i could help!

I'm also surprised the dealership didn't suspect it was the battery...
