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.

My husband had just left our home and luckily were still in our neighborhood when our mazda cx9 started to stutter and shake and become un-drivable. It rode very rough. It happened with absolutely no warning. We took it to the local repair shop and was told that the check engine error was p0351/po352. They replaced the coil but the problem persisted and we still were unable to drive the car. We then took it to the mazda dealership which then replaced the PCM and another coil. We had to wait several weeks for the PCM due to "limited availability"; which to me, a consumer means one of two things - the PCM should not fail or there is a short supply of PCM because there are many failures. I spoke with mazda and the customer service representative researched the problem and called me back to explain that this current situation "did not meet the federal parameter of the review process and that mazda would not be replacing this part for us and she added "at this time"...seems suspicious to me..."at this time". What does that mean? Mazda's warranty is 8 years/96,000 miles...that is unacceptable (our mileage is 116,000). We were lucky we weren't driving on the highway at a high rate of speed or the car would have just stopped running! Our car had no previous issues, the check engine light did not come on until this incident on 11/16/2014.

Was driving on interstate at night. Engine light came on and car immediately drove as if it were not operating on all cylinders. Took it to dealership and it had multiple misfire codes, 301, 351, 352, 354. I researched and found multiple complaints filed on-line regarding the exact misfire codes I experienced and PCM issues in this particular year, make and model. This problem is way too expensive to fix on a personal level. If mazda is aware that this has been an issue, they need to remedy it. I do not believe I need to personally pay for a PCM when this appears to be a common problem in this make and model. I believe mazda is very aware of this problem, and they need to remedy it and replace the PCM.

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.

Was driving on interstate at night in snow; unsafe and unknown area with just me and my daughter. Engine light came on and car immediately drove as if it were not operating on all cylinders. Took it to dealership and it had multiple misfire codes, 301, 351, 352, 354. Coils bad and PCM "fried." car is only 5 years old and last car payment made october 2012. I researched and found multiple complaints filed on-line regarding the exact misfire codes I experienced and PCM issues in this particular year, make and model. This problem is way too expensive to fix on a personal level. If mazda is aware that this has been an issue, they need to remedy it. I'm perfectly fine to pay for replacement parts at the time mazda recommends they are due; however I do not believe I need to personally pay for a PCM after 5 years of use when this appears to be a common problem in this make and model. I called corporate mazda to ask about any known PCM problems on 3/6/2012, reference # 146248920 and was not given any information. I was told to simply trust the technician. This answer is not acceptable. I believe mazda is very aware of this problem, and they need to remedy it. I will pay for new coils and new spark plugs as those are due, but mazda should replace the PCM.
