Brake Grinding Noise Problems of Mazda CX9

The front brakes make a grinding noise when repeatedly applying the brakes when going downhill or slowing repeatedly from speeds of 65 or so. I believe the brake parts become hot and create something google searches call "judder". I have had the steering will start shaking as well. After repeated requests to Mazda corporate and visits to two dealers, Mazda claims the brakes work as designed. One service manager at browning Mazda stated the front rotors are too small to stop a car of this weight, but this statement is not written. Regarding the vehicle stability control, when I turn left and go downhill from my driveway at a slow speed of approx 10mph, I usually have no throttle control. I need to apply the brakes to regain any control of the throttle. Once again two dealers tell me this is within design specs. Maybe this is true, however, I have no way to immediately get out of the way of other cars as I have to brake first for the throttle to return. Doesn't seem right to me. Also, my combined mpg is about 13. 7 when Mazda states it should be about 18. How can they make such a claim like this and get away with it. It is not just my cx-9, many people complain on the internet. Again, Mazda states the car is within specs.

I have been having issues with the brakes mostly when raining or snow. At times when I go to hit the brakes they get stuck or make a grinding noise and don't want to stop. This has happened numerous times and almost caused me to hit another car on multiple occasions. I will take it in soon to have it checked now that I see that I am not the only person with this issue. Starting in Jan 2015 I notice a burning smell coming from under the hood of the car. I had an oil change and checked for an oil leak to find nothing wrong with the vehicle. After running the car for at least 20 minutes the smell continues.

The Mazda Cx9 that we purchased has a acceleration problem when we go to stop. . Mazda has never been able to solve the problem completely. . We have had 2 brake boosters replaced under warranty. We feel the car is unsafe to drive and Mazda has not addressed the problem. They tell us nothing is wrong with the car. It know also has transmission problems with squeaking and grinding noises coming from the car. This is a design flaw that has not been addressed.
