“Since I bought this vehicle in 2010 I have been experiencing raw fuel smell and catalytic converter smell occasionally. It seems to happen most often when a small hill is climbed and when going down subsequently. I mentioned it to the dealer a few times but they said it was the wind! I never had these strong smells with any other car that I owned.”
