Keep the rear window closed when you drive.
I just noticed the smell from my car yesterday when I did some highway driving with the tailgate window down. My back seat passengers complained of a really foul rotten egg smell. When I closed the tailgate window, it went away.
Some of you have compained of getting the smell with the windows rolled up. I haven't experienced that problem, fortunately.
But even so, what is the point of having a power tailgate window if you can't use it while driving? If Toyota doesn't do something (i.e. recall or post a TSB), I have to admit my trust in their name will be tarnished.
This was as true of a 1960s station wagon as it is of the 4Runner today.
That is why, on page 29 of the 2003 4Runner's owners manual, there is a big yellow box labeled "Caution" that reads, in part: "Keep the back window closed while driving. This not only keeps the luggage from being thrown out but also prevents exhaust gases from entering the vehicle."
Why does the 4Runner have a power back window? I find it more convenient than the flip-out windows used in some competing trucks.
So does that mean, you can never carry long lumber home from the store, or anything else that needs to stick out the back without smelling rotten eggs?
As well as, people following you smelling it. I follow my friends in their new cars all the time going places. I never smell any terrible smells, as they not smell my 02 GTI.
I didn't smell my friend's 96 4runner with the same open back window, open while driving.
I bought this car specifically for my dog in order to carry her around so she can stick her head out the back. Otherwise, it would have been mdx, or rx300 all the way.
In CA with 03 V8.
Like it says in the manual, roll up the back window when you are driving. Otherwise you will get exhaust in the car. Whether it smells like sulfur or not, exhaust is bad for you.
Yes, CO puts you to sleep and kills you.
My point is why does the 4runner emit so much sulfur smell? I'm a physicist. I can map out the vortex behind a 4runner travelling through the air very well. I understand the low/high pressure situation of the cabin and its relation to the opening of the back window WRT to exhaust coming in or not.
Maybe we should agree to disagree on the issue of whether or not I should be able to drive with the window down.
under no circumstances whatsoever should exhaust get into a closed passenger compartment (he seethed, knowing full well that in traffic, the fumes from every other car in the road are pulled over the hood and into the car by the air intake.)
if you're by yourself on the road and you smell your stinky exhaust, that is a safety problem with your car that the dealer needs to remedy under warranty. again, tell him I HAVE A SAFETY ISSUE WITH EXHAUST GETTING INTO MY CAR and see if they look awake this time. they are supposed to wake up for safety concerns.
Go back and read the rest of this thread. I have the same problem with sulfur entering the cabin with the windows up and A/C on recirc. The fortunate thing abou the sulfur is that is lets you know that something/s wrong with the vehicle (can 't smell CO). I am scheduled to arbitrate on the 9th. Let me know if you guys need help.
JUSTIFICATION
I feel that the condition of Sulfur entering the passenger compartment of the vehicle is persistent and substantially impairs the vehicle’s use, market value and presents a health and safety issue. The condition appeared at delivery and I was told that this is common in new vehicles and this would disappear after the vehicle break in period. It did not. Finally, after waiting for several thousand miles, with the smell still present and stronger, I took the vehicle in to address to the problem and was told that there was nothing that could be done. In fact, Toyota of Ft. Worth and the Regional Customer Service Representative suggested I pursue the repurchase/replacement option immediately. Researching the problem, I have arrived at the conclusions below.
Sulfur Dioxide (SO2) is formed when fuel containing sulfur is burned.
Sulfur Dioxide has an odor threshold. What this means is that if you can smell it, the concentration can be determined. According to the Canadian Center for Occupational Health and Safety, the instant you smell Sulfur Dioxide the concentration is known to be 3-5 ppm (parts per million).
Reference: Canadian Center for Occupational Health and Safety
High concentrations of sulfur dioxide can result in temporary breathing impairment for asthmatic children and adults who are active outdoors.
Short-term exposure:
o reduced lung function
o wheezing
o chest tightness
o shortness of breath
Long-term exposure:
o respiratory illness
o alterations in the lungs' defenses
o aggravation of existing cardiovascular disease
People affected include children, the elderly, and those with cardiovascular disease or chronic lung disease.
Ref: http://www.adb.org/vehicle-emissions/General/Health-sulfur.asp
According to OSHA, The STEL (Short Term Exposure Limit) is limited to 5 ppm over 15 minutes of exposure. Therefore, if the odor threshold is 3-5 ppm and the STEL is 5 ppm, then if the smell is present in the vehicle for 15 minutes of driving, then the Government standard for exposure has been exceeded. This has occurred on a regular basis since delivery of the vehicle.

Hydrogen Sulfide (H2S) is the byproduct of the fuel containing Sulfur.
Eye Effects: Low concentrations will generally cause irritation to the conjunctiva. Repeated exposure to low concentrations is reported to cause problems, including tearing pain and blurred vision.
Inhalation Effects: Continuous low level exposure will generally cause irritation to the mucous membranes, and may also cause headache, dizziness, and nausea. Continuous low level exposure also causes olfactory fatigue. Thus, detection by exposed individual may be ineffective.
STEL (Short Term Exposure Limit): 15 ppm

I’m employed by a major Engineering company in FT. Worth, Texas. While employed here I’ve dedicated a considerable amount of time as a Safety Engineer performing analyses such as this for the various programs. The data used in this analysis is readily available and well documented. Furthermore, the smell is extremely unpleasant and as such reduces the value of the vehicle. Therefore, I respectfully request that Toyota repurchase or replace my vehicle.
Sincerely,

Also, I suppose that carbon monoxide is always a potential problem, but my understanding is that modern engines with oxygen sensors and closed-loop mixture control systems don't produce appreciable CO. CO is a byproduct of incomplete combustion and the modern systems set the mixture up for very complete combustion if they're running correctly. Of course, even a little CO produced on an occasional basis might be a problem, as the body is very slow at getting rid of it.
In auto mode, some amount of outside air is let into the cabin.
This claimed smell is not a Toyota only issue.
On the initial drive home, with the rear window open and front window open, the smell was horrible. Since then, I don't drive with both open, so we have 2 unknowns.
I'll try with both open when i get a chance today.
Again, I'm in CA, so if others are right, our state has the least chance of the problem. I feel for others in the higher sulfur content states. (although your gas is likely to be less expensive)
However, you should not drive in any SUV (whether the 4Runner or anything else) with the tailgate window lowered. That will be just as true of the MDX as the 4Runner. Even if you get a 4Runner and don't have the sulfur smell, you still should not drive with the tailgate window lowered.
so I have two worries reading these posts... one, inadequate or ill-suited treatment of the engine wastes in violation of EPA air quality rules and DHEW health and safety requirements... and a car design about as proof against gassing the driver and passengers as the 1961 corvair.
somebody show where I am misinterpreting this, I would like to know that we don't have a major automaker this derelict.
yes, I have an ax to grind here, I'm asthmatic, and I want all the stinkers de-stunk. all of 'em. whatever it costs the manufacturers to do this, they need to spend it. now.
I suspect,as swschrad does, that there is a body integrity issue here that is sporadic in nature and not easily or cost effectively repaired. Any more folks with this problem please post.
Also, I plan on printing this board out and presenting it at my arbitration. Can I do that, legally?
hey, I like the sound of that. gin up a flag, raise an army, and I got a future
Be careful about what you copy.
I have to disagree with that argument by reason that the sulfur smell only occurs sporadically. Your argument would make sense if the car emanated sulfur odor 100% of the time so that the driver would always be alerted to CO. But that is not the case. Why would Toyota fabricate an odor emanation warning system to work unmethodically? Are we in any danger of passing out from CO poisoning if it weren't for the warning smell of sulfur? Clearly not. I firmly believe that this problem needs to be addressed by Toyota. The fact that this message board exists is enough testimony to that.
Bringing in the posse to show that 100 people are having the same problem takes away the "uniqueness" of your case and usually disqualifies you from any legal proceedings.
Tread VERY carefully...
The comment regarding the positive side to Sulfur being in the cabin was that, if it wasn't there, we'd be none the wiser. The point: I'd rather find out that my car has an emissions leak by smelling Sulfur than passing out from CO poisoning and running into a light pole.
It's similar to the addition of sulfur to acetylene; thereby alerting the welder of a potential hazard.
if this was a bar bet, you could get away with a lot less. the amount of the claim is somewhat larger than small claims, and certainly up where felony fraud is counted in every state, so the wisdom of preparing evidence for firm effect and covering your backside should be easily seen.
you have stated earlier that you perform risk reviews and so on as part of your living, tacoviva, but some drift-by web readers may not appreciate as you do what constitutes good scientific and legal evidence. thus I am belaboring the point for the others.
our self-selected non-scientific sample of thoughts may be good tips on things to chase that might provide further solid evidence documenting your loss. I doubt that the Supreme Court is going to quote me in its next session as an authority might get some high-fives if you hang it outside your cubicle, might not.
To prepare yourself, you have to determine the amount of the devaluation and the actual breakdown and reasons - you can't, as a consumer, just say "I've lost $5,000 because I think so".
If I build widgets and say, Lot 1 was produced with faulty parts, then those widgets in Lot 1 are worth less than the other Lots produced (assuming the problem is fixed). It's like PCs with Celeron processors. They are basically chips that didn't meet spec (the yield is lower) to be called P4s, as a result they are devalued by a certain amount and sold.
Proving the hazard, not just your assumption of a hazard (meaning with test equipment, not just a sensitive nose), is the key.
What I've been saying is that based on many, many vehicles giving off sulphur smells, in my opinion, there IS NO devaluation. I've seen several cases like this get nipped in the bud and the firm quit taking them.
I wish you luck. Without proof that noxious levels of gases are entering the cabin, there's no case.
the only advice I have ever seen if you have to do it to bring some lumber home from the yard is to crank up the blower to full power, and/or open some side windows.
and I can tell you, there will still be some exhaust coming to you even if you have the air vents blowing bugs at you like you were on a motorcycle with no wind shield and no helmet.
I think Tacoviva has a point that not many other vehicle owners have had. Based on his description, his vehicle actually sucks the exhaust gasses in, even with the rear window up and the system on re-circulate. The vast majority of other owners who have weighed in and claimed to have the issue stated that their rear window was down...a totally different circumstance and, IMO, not likely to be an actual defect.
The whole concept of lemon law is the uniqueness of YOUR vehicle and its problems.
If you can't prove toxic levels of emissions are entering the cabin, all you have is the fact that your vehicle gives off the same smell that 2 out of 10 vehicles on the road - and you're not unique in your situation.
Is it up to me to hook my instrumentation up to my vehicle? I don't think so. Toyota has admitted the presence of Sulfur INSIDE the passenger compartment, now I believe that THEY are responsible for showing that the concentration does not violate the STEL per OSHA spec. Where I work, If our customer discovers a potential problem, we spend our resources to determine the hazard risk level. I understand your position, however, if you drive one of these stinkbombs, you would certainly think that it's highly objectionable.
After 3,500 cases in 2.5 years, I know how these arbitrations work - I'm just trying to let you know what you need to do - I'm not saying it's right or wrong, it's just the way it is.
The plaintiff has the burden of proof - period.
With a meter, it doesn't really matter if your sulfur olfactory threshold is 500ppm, and his is 500000ppm. The judge here cares about your measurement and your 3-5ppm OSHA doc.
just a thought.
horse dovers, I say. burning fuel loads the cat up with sulfur, burning more isn't going to clear it.
sounds like fancy dancing while herding you towards the door to me.
Do you understand that you should never have emissions inside the vehicle, including ammonia.
So premium is required now to go from Sulfur to ammonia. If it weren't a hazard to your health I'd say that sounds rediculous; however, it's anything but.
