Emission Control Problems of Toyota 4Runner

1. 2004 Toyota 4runner purchased from fred anderson Toyota, 9101 glenwood avenue, raleigh, nc,27622 on 3/18/2004. On 3/29, the service department installed an electrochrmic mirror that had been ordered at the time of purchase. 2. After that I noticed that the engine warning lights, the vsc trac and vsc off light came on in the dash. Also noticed an ammonia smell. 3. I took the vehicle in 4 times for each problem, for a total of 6 times. The first time 4/15, the problem was diagnosed as the purge valve and it was replaced. The second time 4/29, the charcoal cannister was diganosed as the problem, but the part had to be ordered. The third time 5/6, , the charcoal cannister was replaced. The fourth time, 5/24, it was found that the electrochromic mirror was installed incorrectly. The lights have since gone off, but the ammonia smell still occurs intermittenlty during acceleration. I am currently in arbitration because Toyota has been less than willing to cooperate with me. I'm also wondering what permanent damage has been caused to the vehicle. Additionally I have also noticed a vibration in the steering and noted it at the last two visits to the service department.

In March of 2004, I purchased a 2004 limited 4runner (v6) from rodland Toyota in everett, washington. I have had the vehicle in 3 times now for an obvious exhaust problems. The problem is that when driving the car the exhaust is entering the cabin of the vehicle even with the window is up. It is worse with them down. The dealership has told me each time that they do not smell it and have now idea what it could be. They did however give me a notification from Toyota on my 3rd visit that Toyota says it is the gas I am putting in it. I have tried all different types of gas from chevron to arco and everything in between and the smell does not go away. Now that I have read all of the complaints from people on their 2003 4runners I am irate! all of the dealerships obviously know that this is a problem already and yet they continue selling the new 4runners! I just spent $39,000. 00 on a SUV that obviously has a serious problem!!!! it sounds like everyone with a 2003-2004 will have to take Toyota to court to get their money back. Something needs to be done about this now! I cannot believe that Toyota is not owning up to an obvious design flaw!! if the vehicle is omitting hazardous carbon monoxide into the cabin it should be recalled immediately! people are breathing poisonous air coming from the vehicle and Toyota does not think this is a problem. I noticed the exhaust smell right after leaving the dealership when I bought it and now 6 months later it is as strong as ever. I would advise anyone who wants to buy a 4runner to buy a different car all together. I traded in a 1998 4runner for this bad smelling piece of junk! I want a full refund and Toyota can give it to me plus the interest I have been paying!!!!! do not buy one of these cars!!!! they are junk!!!!!.

I have experienced a strong sulfur odor in my new 2003 Toyota 4 runner since I purchased the vehicle. This smell has not gone away, and in fact has gotten even worse. I use the vehicle for towing purposes also and the smell is unbearable when towing something. I have retunred the vehicle to the dealer on several occasions and have been advised that there is nothing hat can be done. The dealer keeps trying to advise that it the fule choice that I make, this cannot be true since I travel within three states and rarely fule at the same sights, and utilize a variety of different brands also, and since this problem appears to be nationwide how can the dealer insist that it is the fuel? I have gotten to the point that I do not want this new vehicle, its a great vehicle toher than this problem, but when you cannot ride in the vehicle due to the smell, headaches, and when cleints get in . . . Its down right embarrasssing !.

Exhaust odors enter cabin under middle, heavy acceleration, even with windows closed. Strong choking hydrogen sulfide, rotten egg smell, lingers in the cabin for a minute or more each time. Exhaust makes mechanical valve train noise, sounds like pinging or sticking hydraulic lifters on moderate acceleration.

After a very frustrating and disappointing experience with a GMC SUV we bought a 2003 Toyota sr5 4runner. Up to this point we have been pleased with it. However, an ammonia/sulfur odor has been noted inside the cabin when driving and causes extreme irritation and a burning feeling in the throat and lungs of anyone in the vehicle. They all immediately complain. We have never experienced anything quite like this. We checked this site to see if others have had the same complaint. . . . They have. We talked with our dealer about it and were told it was the nature of the fumes given off from the fuel. We believe a wind deflector/rear spoiler may help this problem but also learned from our dealer that one is not made (yet) for this model 4runner. This physical irritation and burning felt while driving is totally unacceptable and we hope more complaints filed will cause enough concern to get something done. Either with the fuel or a product to eliminate these odors from entering the cabin.

The sulpher smell/carbon monoxide that comes into the cab of my '03 4runner v8, is extremely unacceptable. This is my 4th Toyota in the past 6 years and I have never been more dissapointed with my vehicle. Took it to 4 dealers to all say to me that it's a gas grade issue. I'm tired of Toyota not standing behind their product and helping loyal customers out with annoying issues. At the very least, offer an altenative system.

I purchased a 2003 Toyota 4 runner in November 2002. This vehicle omits a sulfur smell that is easily detectable and horrible to have to smell when driven. It plain stinks. It stinks with all windows up. It stinks worse with the side windows or sunroof open. I complained to the dealer the day after purchasing the vehicle. I have brought the 2003 4runner to the dealer numerous times and emailed complaints about the sulfur smell to Toyota USA to address the fact emissions were entering the cabin. I even met with a regional tech from Toyota USA on two occasions. Each time Toyota failed to remedy the problem of emissions entering the cabin of the 2003 4runner. The sulfur smell being omitted into the cabin is awful to breath for not only myself, but anyone else traveling with me. I have no idea what health hazard the sulfur smell poses or what other emissions must be entering the cabin. I have been complaining to Toyota for almost one year about this problem, and recently I learned the issue of emissions entering the cabins of other the 2003 4runner is being widely reported by other 2003 Toyota 4runner owners. Toyota has failed to remedy this design defect with me, or address the health/safety issue of emissions entering the cabin with me. The 2003 Toyota 4runner is defective and should be recalled to effectively correct the fact that emissions are entering the cabin of the vehicle. In addition, Toyota has been firm in their position that the vehicle is operating correctly, they are covering up a known defect and need to be held accountable. I would appreciate a response from NHTSA. Thank you and best regards, bill valentine.
