There is a systemic evap system issue where there is a leak that either shows that the gas cap is off or the check engine code for large evap leak. Message board traffic shows this as a problem across multiple year models and makes in the Mazda cx line, especially the Cx-9. everyone, including myself, reports the same issue: Light comes on, and then replace gas cap. Light comes back on and then it is multiple trips to the dealer for them to find where the evap leak is.

I took the car to pep boys and they told me to call because my whole gas tank is bad and it should have a recall on it.and also Ford said the same....so my truck have a major gas leak and a rusted out gas system.

Traveling on interstate engine suddenly starts to stutter. Push down on the gas and there is no power. Car cannot go over 40 mph. Engine light comes on. Take car to my local mechanic. Informed that ignition coils #1,2,4 are ruined. They are replaced, 12 hours later ignition coil #2 fails again. Mechanic gives me Mazda bulletin #01-026/11 calling out issues with PCM and how PCM will cause mis-firing of ignition coils causing the coils to fail prematurely. Coil #2 when replaced was charred and split and was leaking oil. Mazda would not acknowledge problem and would not replace PCM or damaged coil caused by faulty PCM.
