Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Car has rotten egg smel when heat is turned on. Contacted Toyota and was told that it's a consequence of the gas and that they will try to fix it but that it will probably not work. This is unacceptable after paying for a new car.

Vehicle is having a problem with the catalytic converter. Owner took the vehicle to the dealer and had the problem diagnosed. However, the dealer was not willing to assist the owner and told the owner that she'll have to live with it. Provide further details. The consumer continued to complain of a rotten egg smell. The dealers response was a high sulfur content in the fuel that could not be fully eliminated

There is a sulfur smell when the heater is blowing, and when the engine is shut off. Took vehicle to the dealer, and dealer claimed something was in the gas.

I bought a 2004 Toyota Corolla from team Toyota. It started emitting a rotten egg smell. We took it to the dealer on the first occurrence and we were guaranteed the smell would go away after the first 5000 miles. I thought that sounded fishy, so I did some research online. I found that many ToyotaS are emitting the rotten egg smell. So I contacted the dealer again. I told him about my findings. I also told them how aggravated I was with them about lying to me. Low and behold they were aware of the problem the asked me to bring the car in again to be checked. After the car was looked at a second time. I was told that Toyota was aware of the problem and that it was the gas and that they are not going to address this issue with me any more. I was even given a letter stating ToyotaS stance on the rotten egg\sulfur smell issue. I have since contacted a lawyer and IM in the process of suing. (there is more to the story but you get the idea). After more research I have found that: Epa has been made aware of concerns regarding sulfur odors. It is my understanding that in 2002/2003 Toyota replaced the nickel based catalytic converter lining with a non-nickel containing compound in order to reduce the exposure of its employees. Nickel is a toxic compound. We believe that new lining currently in use, specifically in 2003 and later Toyota models, does not handle the sulfur in gasoline as well as the former nickel compound. Therefore resulting in the sulfur odor you are noticing in your vehicle.

Bought the car new on 8/30/03. Has had a sulphur gas smell at low speed & when stopped in traffic inside the car. This happens with the windows up & either heat or air conditioning on. It makes no difference when the controls are set to recirculate inside air instead of fresh air intake. Called dealer 1st time, they said catalytic converter needed to burn in some. After some time, the smell hadn't changed, I took it to their service dept. They found no problem, said to try a different brand of gas & also try higher octane. I have tried all the major brands of gas & mid-grade & premium gas (which the owners manual said is not required), with no change noticed. We called Toyota customer service, who said to call the dealer customer service, which we did twice with no response. Called Toyota customer service back with this information & they said we could try arbitration but they had not seen the manfacturer do anything for this problem. This is an ongoing problem & extended intake of sulphur fumes cannot be healthy for anyone. The incident date is the date the dealer checked the car.

When car is running exhaust produces rotten egg smell which when vent is on comes into car. Brought car to dealership and told condition is normal for this model and would not correct under warranty. I find this answer unacceptable that I should drive a new car that emits rotten egg smell as normal.
