I was driving home on a busy interstate when my car started shaking and losing power. They car lost all power and I couldn't turn the steering wheel to get out of the way of other drivers. I was almost hit more than once by other cars. After having the vehicle towed and a licensed mechanic look at it, I was told the water pump failed and leaked water and coolant into my engine which completely disabled my engine.

The ptu transfer case is defective and needs to be replaced, and will cost almost as much as the car is worth. After some research, this is a very common problem due to the design that mazda has refused to acknowledge and recall for many years now. Common problems are explosion of the unit and toxic fumes and locking up of the power train. Please do your job and take action.

Takata recall - in the last 1 1/2 years, I've received numerous recall notices for the listed recalls and have taken my vehicle and called in to the mazda dealer to see if they have the replacement. The dealer keeps telling me that there are no replacements yet in the sytem. I don't have exact date that ii had previously make a complaint.

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!

Tl* the contact owns a 2007 mazda cx9. While driving approximately 75 MPH with the cruise control activated, the vehicle downshifted to neutral on its own. The contact switched to manual transmission, but the vehicle would not accelerate. The contact had to coast to the shoulder. When the vehicle slowed down to approximately 10 MPH, it re-engaged in gear. The manufacturer was not notified of the failure. The VIN was unknown. The approximate failure mileage was 127,000.

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..

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.
