Strong sulfur smell while driving car. Has been present since I bought the car almost one year ago this August. Dealer said had to do with additives in gasoline and should stop, but hasn't stopped. Especially strong in the mornings after car has sat over night.
Sulfur like smell enters the car while running, especially evident in wet weather. Garage says Toyota has sent out a technical advisory stating the gasoline is the problem. Have not had a problem with any of the other vehicles I drive. I believe the issue may well be the placement of the fresh air intake in relation to the exhaust system (?). It tends to make one have headaches while driving. This has been ongoing for at least 4-5 months. 2003 Toyota Corolla, new.
Purchased 2003 Toyota Corolla in October 2002. Car is emitting a very noticeable sulfur odor especially when coming to a stop at traffic lights particularly when the engine is cold. I have taken it to the dealer twice and was told the problem is the gasoline I purchase. According to my dealer, some gas stations put an additive in the gas that creates this smell. I have never had this problem with any other car.
