Replying to: lear02 (Oct 13, 2004 1:42 pm) That's a good idea if Toyota Motor Co. is not aware on this issue. This is absolutely health hazzard. Please keep posted the result.

I don't understand at this point how your car can be filling with carbon monoxide (even though I certainly believe that your car stinks inside) without you being too dead to post, or, if not, at least seriously impaired with typical CO poisoning symptoms.   How have you determined that you have CO in your car's interior?   The reason I ask is because that's a pretty startling claim and should therefore have startling evidence.

#737 of 862 Stinky exhaust health hazard? by corancher Oct 14, 2004 (8:44 am)
Well, maybe not. I won't consume bandwidth by recapping all the previous discussions here, but would encourage anybody who cares to read extensively in this discussion.   In summary, today's engines burn so clean that the old carbon monoxide problem (due to incomplete combustion) doesn't usually exist. It's a stink nuisance and would probably be improved if Toyota went back to the side-firing exhaust they used to use. Stink is probably coming from the rear cabin exhausts, so you can often avoid the stink by simply leaving the system on fresh (rather than recirculate) and having the fan on at least the low setting.   If the stink is a problem, get the TSB(s) and keep leaning on your dealer and, by all means, complain to Toyota too. This kind of thing shouldn't be happening, but it's not unique to the 4Runner or to Toyota.

Replying to: Mr_Shiftright (Oct 14, 2004 8:36 am) The sulfur smell tells you that there is exhaust fumes entering the car.The exhaust is carbon monoxide . No matter how you look at it exhaust does not belong inside the car. And changing from one make of fuel to another is not the answer. Replies to this message: biyo (Oct 15, 2004 6:59 pm)

All true but I don't see how you could have any appreciable amount of carbon monoxide in your truck. What I'm driving at here is that this claim substantially diminishes your credibility in an arbitration, since if you were breathing carbon monoxide in any harmful array you would be very sick indeed. We all breath a bit of CO every day of our lives unless we are really living in the woods or something.   So I am suggesting you drop that one and stick to the obnoxious odor as being very annoying rather than life-threatening.

Replying to: Mr_Shiftright (Oct 15, 2004 12:54 pm) Suggestion well taken.I know that you know the obnoxious odor is from the exhaust system. If the CO content is 1% and 99% other gases thats still an extremely unhealthy environment to be driving in every day. Toyota knows it has a problem. They do not know how to come to terms with it. Maybe do to cost? This may become a class action suit time will tell. We all have big money invested in our cars and we deserve the best ride we can get.The one thing to remember here is the exhaust is getting in side the vehicle.
#742 of 862 I've been involved by driftracer Oct 15, 2004 (3:44 pm)
in class-action evaluation on this, and after testing, we determined that there's no more noxious emissions in a new 4Runner than in several other vehicles tested. Comparitively, when tested by itself (4 vehicles), they were 70-80% less in cabin emissions, driving by themselves on deserted roads, than just driving the vehicle in normal traffic.   If you can't tell, I'm NOT a "sky is falling, let's sue everybody" advocate. We have become a country of victims and plaintiffs instead of men, women, and consumers.

Replying to: lear02 (Oct 14, 2004 12:00 pm) I've sendeng e-mails to Toyota Motor Co. copy to the director of my dealer, Toyota Motor Company said that TSB is not funded yet, and told me to contact the Customer Relation Manager of the dealer, I spoke with CRM and told me that they have to diagnose the vehicle but I doubt that even they will running for 2 hours, maybe they can't duplicate the problem due to the odor is not there all the time. Also I receive an e-mail from Dealer Service Director that asking me to make an appoinment and tell about the TSB and let him know once my car at the dealer. I will keep posted what ever the result.

Replying to: neumie2000 (Aug 23, 2004 9:24 am) I'm sure that changing fuel brand is not the answer. Replies to this message: neumie2000 (Dec 06, 2004 6:02 am)
