CarComplaints.com Notes: The MAZDA6 was redesigned for the 2009 model year. Like any first-year product, it has a few growing pains – most notably a shiny, melting dashboard that can blind the driver.

My 2009 Mazda 6 I touring at during driving at 20-25 mph or at 50-80 mph produces a sulfur emission from the air vents inside as well as from the exhaust pipes. This began when the odometer was just over 300 miles. Even though this car requires regular unleaded octane rating 87 gas, octane rating 92 has been used as well as generic brands of gas. Since switching back from octane 92 gas to regular unleaded octane 87 gas (as advised from the metro Mazda dealership in MA) and from the generic to a more recognized brand of gas (mobile), the sulfur emission from the air vents has been greatly reduced to become a rare occurrence, but is still there, as recent as 10/22/09 on the highway with about 4200 miles on the odometer. The sulfur emission still comes out from the exhaust pipes and is most notable in the garage whether the car is running or not. The smell is still noticed when outside, running or not, and happens frequently, almost every time the car is shut off. Whether distance in travel is short or long, the emission from both areas remains and has been ongoing since the first occurrence.
