exhaust smell,sulfer -after car has been driven and warmed up
car has 6000 miles on it sulfur exhaust smell dealer said it was cheap gas i have 3 other cars with same gas and no sulfur exhaust smell from them
Try the dealer suggestion - switch fuel for a tank or two. Then, return to the dealership with the results. If the sulfur odor is still there, make sure the delaership acknowledges the problem. The vehicle is still under warranty, so the dealership can check and repair at no charge.
