I purchased a 2003 4Runner, V8, sport edition. I started smelling the sulfur, the day I brought it home. I called the dealership immediately, but they told me that it was the gas. This was the same gas that they filled it up with(Mobil-87). I have since tried every different kind of gas in my area. The only gas that seemed to work a little better was Amaco 93. I have contacted my dealership again about this problem, they told me that a service bulletin was sent out to them, that recommends using 91 octane or higher. This is a problem, when I bought the 4Runner in July of 03, the sticker on the window recommends 87 octane, now their telling me I have to spend more $ on gas so my truck doesn't smell like bad ass. The smell is so embarrising, when friends and sometimes clients are in the vehicle. With the money I spent, there is no way I should have to put up with this smell. I love everything about the 4Runner, except that horrid smell. This was the first Toyota I have ever owned. Unless this problem is corrected, I will not buy Toyota again. I am going to talk to a lawyer in the near future. I am so disappointed with the way Toyota is handling the situation. I have met with many people in my area that have 03 $Runners & Sequoias and not one of those people, had a problem with this sulfer smell. If the smell is because of the gas, then why are these people not getting this horrid smell in their vehicles?
