1 Transfer Case problem

Failure Date: 02/28/2018

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.

2 Transfer Case problem

Failure Date: 04/08/2014

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. .
