Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

I have only had this car for one year. I bought it used and have had the "same" problem now "3" times and since I have not had it fixed at a "Mazda" dealership because I am sorry I do not have the $$$ for this and I brought it to my own mechanic, Mazda will not stand by this. The ignition coils have all been replaced now as well as the PCM and now I am told it needs the PCM to be replaced again. There are "numerous" complaints on the internet for this exact same issue and most have taken it to Mazda dealerships and still have no resolution to this problem. The last coil actually melted and could have started a fire so I am running with 5 coils now instead of 6 until I can find out how to rectify this ongoing problem! I just put 4 new tires on the vehicle and have spent over $1000 already and can't afford to spend much more on this vehicle. Mazda needs to stand by this problem!

I have just learned about issues with the Mazda CX9 and wheels falling off and I realized that is exactly what happened to me. I always took care of my cx 9 because I drive a lot for work and depend on my car very much, so when issues with the steering started I took it to sears for a wheel alignment since I had just replaced a new set of tires a couple of months before, it seemed ok after the alignment until again the small skip of the steering started every time I turn the wheel, I did think much of it until it started increasing. Every time I turned the wheel the skip was there, I decided to call my mechanic who always did all the car service and maintenance and he said to bring it in over the weekend to take a look, before I had the chance to bring it to him, as I was making a right turn the wheel came right off the transfer case and the arms, good thing I was just making a right turn, minutes before I was on the highway and I don't even want to think about what could have happened... I thought it had been just a freak accident and I was happy to be alive. I had the mechanic come and pick up the car from the street and after surveying the damages he had to replace both upper and lower arms on both sides and then he noticed that the transfer case had been damaged when the axel pulled away, so now we needed a new transfer case and it is not an easy job. Now that it is all done I found that it has happened many times, this is not right and makes me angry to know that the owners were not informed right away, I could have had my children in the car..

CX-9 6-cyl

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.

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.
