Sulfur Smell from Toyota 4Runner



  • Hi -- wanted to let you know I contacted Toyota 1-800-331-4331, and questioned them about the TSB and I was told that my vehicle does not fall within the parameters of it but they would go ahead and open a case where the dealership needs to respond to corporate within three business days. My dealership called me 4 hours later and they've ordered the new catalytic converter and will replace it once the parts have arrived. The service manager was very helpful and polite. He'll also be ordering my new visors since my 4Runner is part of Campaign 30G where certain vehicles did not receive vanity mirrors on their visors. I thought it was kind of weird there were no mirrors but I never questioned it -- but Toyota Corp in California did and now I get my mirrors -- I'm so vain!! :blush:

    Where do you get the TSB from? I'd like to get a copy before a go to the dealer. From reading earlier post I believe it's TSB EG004-06. Anyone have a link? The trunk only has 550 miles on it and I smell it already.

  • The tail pipe is too short, and should be have a right-angled piece added on the end of it.

    Hi, I'm having a huge problem with my 4runner smelling like eggs. The Toyota rep is coming out to talk to my husband and I on Wednesday. I'm sure that he is just going to give me the run around like every other Toyota rep, so I plan on going to arbritration. Do you have any suggestions? I would really appreciate it. Did you get your 4runner repurchased or replaced? Thanks for your time!

    ktodd, did you read the messages in this forum? there is a TSB on the 4runner (and on other models) calling for a reprogramming of the ECM (Engine Control Module), and replacement of the Catalytic Convertor.

    just one question... were you driving anywhere near the Whitehouse???? ;)
  • i have a 2006 4runner that smells every time i drive it, it is so unbarable i get sick from the smell. the dealer keeps telling me to change gas and it is a normal thing for new cars. well the b.s. keeps changing they changed the exhaust front pipe subassy r&r and 2 weeks later the smell is back.$30,0000 truck and they think I am going to smell this everyday you're joking right? furthermore what about the enviroment and health issues this could potentially cause some serious side effects that i don't want to take.
    please reply if you're experiencing the same smell with your 4runner

    Merolle - I too am having the same problem. Every time I accelerate, the smell is so obvious that I get a big head-ache. The dealership replaced the catalytic convertor but the smell resurfaced 2-3 weeks later. Also, my average mile per gallon has decreased by 2 miles. I'm supposed to drop it off this Wednesday. Probably get the run around. Let me know your status or anybody else having the experience, please share with us. Thanks

    You need to make sure that your dealer used the convertors from the TSB. Do you get the odor with all 5 windows up while driving down the road?

    Hi...Are any of you still having issues with the sulfur smell, and if so, how have you handled it. I have a 2003 4Runner and have notice the smell as well.
  • If you still have the vehicle, take it to lemon law arbitration. There may be a time limit so you may want to check. I got all my money back plus interest on my 2003 runner.
  • Hi this is really bob443, I started this over three years ago, but I did a login id and password that I do not remember. Any way lets update everyone on what the situation is with Toyota and your options with the sulfur mell:

    Basically there is nothing you can do. It's a matter of them using a different Catalytic converter (a cheaper one). I took this trough the Arbitration court and lost. I tried hard and based my issue with the fact that the smell was putting my child's health at risk. It didn't work. So here is what you can do:

    1. Buy the attachment that pushes the exhaust pipe out to the side and then it won't come into the windows as bad.

    2. Your best bet if you don't like the smell hook up your car to run E85 and you will smell french fries instead.

    3. Buy a Honda.

    I don't mean to be harsh but I am so fed up with Toyota and I have since sold the 4Runner.

    Good luck, sorry I don't have any good news to report.

    There was a TSB that called for the dealers to replace the Catalytic Convertor and reprogram the ECU.

    EG020-04, EXCESSIVE SULFUR DIOXIDE ODOR, 2003 – 2004 model year 4Runner vehicles equipped with the 2UZ–FE engine produced BEFORE the Production Change Effective VINs listed (see the TSB for the VIN #'s).

    see message 808.

    Factually, Toyota had issues with a number of models with CAT Convertors that were probably defective.

    Good luck.
  • Oh ya we took it in and had the Catalytic Convertor changes and re programed but I am just a consumer who can't tell one Catalytic Convertor from the next but it looked like they put in a new one but it must have been the same type that they are using when they build the 4Runners because the smell was still there. That's when we took it to Arbitration and lost.

    did you do this BEFORE the new cat was available? replacing it with the same CAT and just doing a reprogramming probably wouldn't help.

    did you try taking it to another dealership? because the new P/N covertor and the reprogram should have helped you.
  • Is there a VIN search I can do? Driving with the windows down is tough in MI when it is 20 degrees out.

    I have an automatic 2006 Sport Edition 4 Runner. Most time when I shift the gear to drive, the transmission takes awhile to engage; It's let driving a manual when you're trying to push the gas and it just sits there until you release the clutch then all of the sudden (4-6 seconds later) the transmission catches. It's been a year since I have the car and it is happening more often and now takes even longer for the transmission to engage.

    I had this problem ever since I bought the car a year ago. Every time I take to the dealership, a mechanic will drive the vehicle and he does not see or feel the problem. They plug a computer to it and get no reading. It's getting very frustrating because friends who ride with me are experiencing the problem and the dealership don't. Not sure what to do or if anyone else is experiencing this as well. Sounds like I have a bad transmission but cannot prove it.
