2 weeks ago, I started smelling a gas odor coming from the front of my car as I drove. Then as I started it and stopped it ; I smelled it. Now it smells like exhaust all the time. I took it to the dealer today and they went over the entire exhaust and gas system and said it is fine. They agreed there is a "chemical smell", but nothing is wrong or the computer system would alert us. I picked up my car and it still smells like exhaust, not a "chemical". my husband and I became nauseous driving after and hour last week and had to roll down the windows. He said he was light headed. It never smelled like this before and I can't stand driving it not only because it stinks but possible carbon monoxide.
