Upon turning off the engine, the exhaust fume smells like rotten egg smell. The Mazda dealer said that there is nothing they can do because there is not a recall on the catalytic converter. The Mazda dealer suggested using only shell gas. The Mazda dealer also reported that there is not enough incidents yet for Mazda to recall the catalytic converter.

There is a rotten egg smell coming from the exhaust pipe from the car. Mazda dealer is unable to resolve the problem when I went back for service. I change gas to shell as recommended by the dealer, and the problem persists. Dealer said that this is comon problem and blamed it on the gasoline blend.

When the car decelerates (braking or down-shifting) the headlights flash. When I take the car back to Mazda service, they tell me that this is a known issue that is effecting many of the new skyactiv engines. They say that there is something wrong with the electronic control unit that is making the lights flash. They state that Mazda engineers have not given them a fix for it yet, so they can't fix it. I believe this is a real saftey hazard. People on the highway think I am flashing my lights at them. I bought a second car (same model and year) at the same time and it doesn't have this problem. When I tell this to Mazda, they act surprised and state that I must have got lucky because most of the cars have these flashing lights. They seem to just want me to live with it. You need to investigate this since they are saying it is a common issue. I think these cars need a recall.
