I own a 2003 4Runner which I purchased new in Nov. 2002 with the obnoxious sulfur smell. I complained about the small bitterly to Toyota and posted numerous complaints with many agencies. When the 6/14/2004 EXCESSIVE SULFUR DIOXIDE ODOR TSB came out, I learned about it through an editor at the Plain Dealer who had written an 6/17/2004 article titled "Customers Driven to Make a Stink". The editor has read one of my complaints when doing his research. I immediately contacted Toyota and had the service outlined in the TSB performed including replacing the Catalytic Converter Assembly. I have not had a single incident of sulfur smell since. My understanding at the time of my service that it was a service of last resort only to be pursued when all other measures failed to satisfy the owner. Unfortunately I had to live with the smell for 1-1/2 years before finally being rid of it forever and the smell certainly diminished the pleasure of owning such a nice rig. Best regards everyone, Bill

I haven't visited this site in almost two years. That was after I took Toyota to Lemon Law arbitration and won.(for the smell problem). It seems like they still don't care. Maybe that's because their stock price busted $100. a share. Don't give up, your new car smell shouldn't be SO2 (sulfur dioxide). You don't need a lawyer, just document every visit to the dealer, every phone call and comment, and do your research on the effects of SO2 and Toyota's negligence or inability to find a solution to this serious problem. If you want any info on this case or have any questions, I would be happy to try and help.

Has anyone with a 2006 model noticed the smell? Wife has noticed a 'rotten egg' smell 3 or 4 times. Could that be the sulfur problem being referred to?
Is it possible Toyota still hasn't fixed the problem or could this be something else?

The rotten egg smell can be intermittent (i.e., you won't smell it all of the time). I had it in my Sequoia and noticed it mostly in stop and go traffic. Toyota has a TSB to replace the catalytic converter to remedy the problem. I don't know why they wouldn't just put this cat. converter in the new vehicles in the first place, since the replacement converter has been around for awhile. I am not sure if there is a TSB yet for the '06 4Runner. You can check with your dealer. At first the dealer may tell you that the problem is related to using regular gas and to switch to premium. I was already using premium gas, so my dealership did a little more research and found the TSB for the cat. converter replacement and this seems to have completely fixed my problem.

Please do not stop people from informing others about the quality of the Toyota 4Runner. My experiance with this vehicle was, and is, that it's got major systems faults. And no, there isn't anything the owner can do about it.
What does Toyota need to do about it? Only one thing. Own up to it. Toyota refused to acknowledge IN WRITING that my car had a systematic transmission problem. Their customer service reps politely took my trouble report, gave me a trouble report number, told me that I'd never have to pay for a replacement transmission as long as I owned the car blah, blah blah. And then they refused to put any of their statements, mainly that I'd never have to pay for a transmission for this vehicle, in writing. "It's not our policy".
Folks ought to know that, before they pay Toyota's "quality" premium and contrary to all the B$, Toyota is no better than other car makers.

No problem complaining in detail and once or twice is fine and good for the forum...but hammering away day after day without solving something, and just to exercise a grudge...well...most visitors complain if someone does that. We all like to move toward some resolution, either finding a solution or going to arbitration or whatever.

My problem was intermittent also.There was a chance that it wouldn't happen if the lemon law arbitrators drove the vehicle. When I advised them that the problem was intermittent, they decided not to drive the vehicle, but made their decision on the facts of the case and witness statements. Toyota kept saying it was the brand of gasoline, but I documented trying at least 8 different brands and grades. If the replacement of the cc did the trick that's great, Toyota wouldn't even do that for me, that's why I went to arbitration.
