Replying to: robg4 (Feb 23, 2006 6:01 pm) 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.

Replying to: Mr_Shiftright (Aug 16, 2005 5:29 pm) 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.

Replying to: dadeo7432 (Mar 01, 2006 2:49 pm) 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.

Replying to: scoti1 (Feb 24, 2006 6:31 am) 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.

Replying to: reddfish2 (Jan 20, 2006 6:31 pm) I'm having the cat converter problem with my 2003 4 runner and the dealer is telling me that he can't just replace it - that I should try low sulphur gas. My argument is that a 3-year old car should not smell like sulphur and that they just need to replace the failing part. Any suggestions??

Replying to: slral (Mar 15, 2006 10:11 am) Ask your dealer to check again for TSBs. The initial TSBs on the sulfur smell problem stated to advise the owner to change grade of gas. There is another TSB that came out that actually calls for replacing the cat. converter. I had it done for my Sequoia and it worked in elimating the odor. If i recall correctly, the TSB came out in the summer of '04. I can't say if it applies to the 4-runner (you can try to look it up at alldata.com or NHTSA.gov), but if they found a fix for the Sequoia cat. converter, why not the 4-runner?   -------------Editting to add: I just read an earlier post in this forum that states the following (i.e., there is a specific TSB for the 4runner): EXCESSIVE SULFUR DIOXIDE ODOR Models: ’03 – ’04 4Runner (2UZ–FE) Technical Service BULLETIN June 14, 2004 Some customers may complain of excessive sulfur dioxide odor on 2003–2004 model year 4Runner (2UZ–FE) vehicles under the following conditions: �� Stop and go driving. �� Heavy acceleration. In order to reduce the sulfur dioxide odor, the Electronic Control Module (ECM) (SAE term: Powertrain Control Module/PCM) fuel cut control logic has been modified and a new catalyst is provided. Follow the repair procedure to reflash the ECM and replace the catalytic converter assembly.

Replying to: scoti1 (Mar 20, 2006 11:23 am) yes, it does apply to the 4runner. I had it done in June 2004 on my vehicle, after smelling the sulphur smell for a few months after I bought it new. They replaced the CC and problem solved. My dealer did not give me a hard time about it, and fixed it for free.

Replying to: robg4 (Feb 23, 2006 6:01 pm) Yes, indeed, I experienced this awful almost throwing up smell like a rotten egg yesterday on stop and go traffic. I have a 2006 4Runner LMT V8 4WD with a little over 1000 miles driven so far. I will definitely call Toyota and dealership to remedy the issue...   I just finished talking to the Toyota dealer and guess what bad news... there is a new TSB EG004-06 that does cover the 2006 4Runners... I am going to the dealer to let them check it out... Replies to this message: agnosto (Apr 10, 2006 7:20 am)
