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.
2007 Mazda CX-9 transmission complaints
Page 2 of 2: complaints 11 to 12 of 12, newest first, as owners wrote them.
We have had our mazda cx-9 since 2007. At 58,000 miles we noticed a "humming" noise. We took the vehicle into the mazda dealership since it was still under warranty. We got the run around stating it was our tires; however, it turned out the front wheel bearings were bad. They replaced the bearings and one year later we are having to replace the rear bearings. Through research we are finding that mazda has a service bulletin issued 2/1/2008 about the rear bearings. Basically stating the noise is from an improper shape of the ABS sensor and this is only covered if there is still a warranty on the vehicle. My question is if they know this is a problem then why is this issue not recalled because a frozen bearing is and can be very dangerous. Mazda refuses to help replace our rear bearing since we are now at 74,000 mile and our warranty is out. All we keep getting is a run around by our local dealerships. We also have had problems with our driver side mirror. Mazda replace the mirror a few weeks after we bought of cx-9 but it still shakes.
