Since I bought the car in Sept 2003 it emitted a rotten egg smell through the vents. I went to arbitration in May 2004 and lost because they said that it was the design of the car. The Toyota rep said that someone wou ld be caontacting me and that they were aware of the problem. No one contacted me and the dealer would not return my calls. The 800# continued to say it was the gas. I have suffered with horrible headaches and I lost my periphial vission on three ocasions. In Feb 2005 I was pulled over sick form the odor and fi again called 800#, they again said it was the gas. I pleaded with the rep to help me and she called me back two days later with a new tsb that came out in May 2004. The dealer reprogramed the ECU and tech smelled odor so they ordered a new cat converter replaced that a reprogramed ECU again. They said it was an internal failure in my cat. If this was the case why was'nt my check engine light going off for the last year and a half? now I have an odor of bad exhaust coming through my vents and Toyota wants me to put in the same gas 4xs. I don't feel safe in this car and I can';T imagine what driving with a bad cat for over a year has done to my health and my engine. I have asked Toyota to issue me a letter saying that the car is safe since I Transport children but they refused.

I bought a 2004 Toyota Corolla type S on December 28, 2003. I've had the car for about 2 months and have noticed an extremely horrible sulfur smell from the vehicle. I have also had the dashboard ripped apart twice, and checked for extremely loud vibrations and noise. The first time, the service department found "nothing wrong, and heard no unusual noises" and the second time, when I test drove it with the technician, they applied some foam around the wiring inside the dash. I can still hear the vibrations and noise in the dashboard whenever I am driving the vehicle.
