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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

Falure of charcoal emmision cannister in my 2003 Toyota Corolla. This is the second time in 4 years that this part has failed. It is my understanding that many other owners of this year vehicle have experienced similar problems. I believe a recall is in order.

While driving check engine light appeared on the dashboard and remained on. Vehicle stalled. But the driver was able to restart vehicle, and drove it to the dealer for inspection. Mechanic placed the vehicle on the diagnostic machine and the codes appeared as follows, P04400/P04411/ P04412. Then, mechanic determined that the charcoal canister and the gas vapor sensor needed to be replaced. Consumer informed the mechanic that the problem occurred many times. Also, mechanic informed consumer that this problem could be a design flaw from the manufacturer.

I have a 2003 Toyota Corolla. In cold weather as the engine is warming up, there is a very strong rotten egg smell when vehicle is stopped. This occurs when the windows are all closed. I would like to know if there is a safety concern.

My 2003 Toyota Corolla emits an overpowering sulphur smell when I come to a stop. The smell enters the passenger cabin and lingers for 10 to 15 minutes. This is an on going problem. My car has only 13,000 miles on it.

Purchased 2003 Toyota Corolla in September of 2002. Car is emitting a very noticeable sulfur odor especially when coming to a stop at traffic lights after driving at highway speeds. Contacted dealer and was told the problem is the gasoline I purchase. I pointed out that I have a 2002 Toyota Camry that I purchased in April of 2002, that I fill both cars with the same gasoline, and that I have never experienced any such problem with the Camry. Again I was told the problem is with the gasoline. The internet abounds with discussion groups where people all over the country are reporting the same problem as I am experiencing.
