#699 of 862 Test vehicles by alfster1 by tloke1 Jun 08, 2004 (10:13 pm)
"However, I can't seem to fathom how apparently none of the Toyota test vehicles would have been afflicted with the sulfur problem. I would have imagined that this problem would stick out like a sore thumb..."   Noticeable problems like this have always bothered me as I also cannot understand why they are not discovered during testing. I realize that manufacturers are not going to catch every little thing, that's rather obvious. But something like the sulfur issue is indeed baffling. For the all-new 4Runner model I would guess that Toyota had at least several hundred test "mules" out there in the real world. These vehicles would have put on thousands and thousands of miles in the deserts, in the mountain and on the streets. One would think that at least a few of the vehicles would have exhibited this symptom. Or, maybe the problem did arise and Toyota decided it would cost to much to re-engineer the parts vs the estimated number of complaints they might have expected to get.   Another classic example of "how did this get by?" is the new Armada and the "resonating roof" issue. On many vehicles the vibrating sound waves are so bad people cannot drive the vehicles. Looks like Nissan cut a few corners and manufactured extra-thin roofs without strong enough bracing. Their solution? A few extra large tubes of glue squeezed on and around the roof cross supports, which does not seem to completely solve the problem for a lot of owners. The entire roofliner must be removed, and in many cases are damaged in the process.   Amazingly, Nissan is STILL producing Armada's with the same exact faulty design. One has got to ask, HOW in the world did something like this not get noticed during the road testing phase? And what morons at Nissan are preventing a solution from being implemented as a running change? As word has spread many sales have been lost and the Armada reputation is getting a black eye.   I think manufacturer's need to "wake up" concerning situations like these. With the power and expanse of the internet it's a whole new world out there for consumers to share both their good and bad vehicle experiences. Negativity towards a given model or about its problems spreads like wildfire.
#700 of 862 Re: Check Engine Light & Sulfer Smell? [fudge123 #680] by bed33 Jun 10, 2004 (5:47 am)
Replying to: fudge123 (Apr 05, 2004 4:39 am) I posted 685 below and offer this follow up. Shortly after posting I called Toyota and gave them the info. They contacted my local dealer. I got a call back from them to set up a service call. I brought it in yesterday and they replaced both catalytic converters per the TSB and said I should be good to go. However, driving it home the VSC TRAC and VSC OFF lights came on and stayed on. I brought it in this morning and they referenced another service bulletin and showed me the procedure. It was a simple recalibration using a hand held unit. They took it right away and I was out of there in about 15 minutes. I drove it in to work about 20 miles and did not see the lights come back on. I let them know the aggravation and inconvenience these issue have caused however to their credit they have very good customer service.

At what number did you call Toyota?
#702 of 862 V8 TSB for the Sulfur Smell by 4rnr Jun 14, 2004 (1:42 pm)
The TSB for the 2UZ-FE engine(V8 powered 4 Runner) has just been released the TSB# is EG020-04. The repair procedure is identical to the V6(which was posted a couple of weeks ago). Replies to this message: gcmello (Jun 23, 2004 4:25 am)

Replying to: 4rnr (Jun 14, 2004 1:42 pm) I'd like to take my 2003 V-8 Sport Edition to the dealership and have the repairs done for the sulfur smell, but I've not been able to find the actual TSB EG020-04 to print out and show to the service manager. I do have a printout for TSB #EG015-04 for the V-6. Any help would be greatly appreciated.
#704 of 862 Sulphur Smell is not all u should worry about! by roguewarrior Jun 23, 2004 (3:07 pm)
Hi I just did a little research on this problem and have learned that 60 complaints have been submitted to the NHTSA for this sulphur smell. What everyone is focusing on is the smell of rotten egg however disgusting and potentially dangerous that is, it is not what will KILL. The Carbon monoxide(CO)is the real danger because it is odorless and deadly it is also getting into the car by the same means as the obvious egg smell. I was so concerned that I contacted a environmental company who came for a ride along in my 2003 sr5 4runner. This ride proved to me that(CO)is indeed entering the cabin and alarmed the tech who came along with a (CO)tester. At one point he yelled "Close the F#%%& rear window". I saw the readings go off the charts depending on the configuration of the windows, with the rear window open being the worst. I did not pay for this test as they were being kind enough to just see if I had any (CO)entering the cabin. This was enough for me! I have since contacted Toyota customer service and I am waiting to hear from the regional rep from FL. Another option for people to find out on their own is to go to the home depot and buy a (CO) tester. This can be plugged into the 110 outlet in the glove box. I did and I do not drive with the rear window down at all any longer. This is a serious problem that may be corrected by changing the location of the tail pipe to vent to the side of the vehicle. I am going to complain to the NHTSA with this post and see if this will get the people who are supposed to protect us "to wake up." If someone else could do a similar test in their state we could have more ammunition to fight Toyota. I have found out that the EPA company would do a complete test with report and all for around $340.00. I am going to see if the service rep would do this but I doubt it. If anyone has the extra money that they could afford to use PLEASE DO IT! I originally posted on a 4 X 4 site I also made a complaint to http://www-odi.nhtsa.dot.gov/cars/problems/complain/complaintsear- ch.cfm the # is 10078432 I have been contacted by the Rep today and he is currently researching. I think I got his attention for a different reason (CO).

Many 03-04 4Runner owners, including myself, drive with the rear cargo window open without experiencing any sulfur or apparently high levels of CO entering the cabin. The longest that I have driven with this window open is 1.5 hours, under varying speeds. I have used a CO tester, but I am not how accurate it is since it was made for home use and is not a professional tester.   Apparently, the exhaust issue only affects some 4Runners, either with or without the rear cargo window being opened, which is perplexing.

#708 of 862 Finally smell is gone by lukeg Jun 24, 2004 (8:31 pm)
I have 04 4runner v8 Sport. Today Toyota dealership fixed the smell problem. They have changed the catalyst and reprogramed the computer. The smell is gone. I don't drive with rear window down, but smell still was entereing the cabin from time to time. Also I am tired of hearing on the street on the red light that my truck stinks like $***. No more bad stink and I can drive with side windows open. Schedule this repair. It takes few days to get parts in. I still have problem with: - sit being loose - vibration with RPM between 1800-2000 - vibrating breaks.
