Three problems related to brake disc pads have been reported for the 2010 Mazda CX9. The most recently reported issues are listed below.
As noted by many on this site, I experienced a scary brake booster failure. Complete loss of powered brakes which put my whole family in danger. This is a family car and I have small children so this is appalling that Mazda would not issue a recall for this problem. I see that there was a TSB and associated extended warranty period for this issue but as many have noted on this site, the true failure tends to occur after the 7 year warranty period. I actually started noticing some issues with the braking on this vehicle years ago, but assumed that it just needed new brake pads and rotors as the car was getting older. If I had received some type of communication from Mazda or NHTSA, then I would have known the true issue during the extended warranty. I only have 77,000 miles on this car, but since it is older than 7 years. . . Mazda refuses to address the problem or take accountability for this quality defect. I paid for the repair myself. Mazda has lost a loyal customer. Shame on them for putting drivers and their families knowingly at risk and not doing the right thing.
Vehicle pulsates while braking while driving fast or at slower speeds. The steering wheel does not shake. The brake pedal does not pulsate. The vehicle brakes were changed several times with new rotors and pads on all four tires. I noticed there was a recall on lower control arms #15v-451. It only was inspected at the time of recall but never changed. Could it be possible that they are now worn and can be changed per the recall.
I purchased this car from a dealer this year with $48,000 miles. It was in tip top shape. Recently the brakes are not working. It is not the brake pads, but a hissing sound in the line and no brakes. The cost to fix is around $1500 and I don't have a credit card or the money to fix at this time. In researching I am not alone with this problem. There are going to be some bad wrecks and problems if this is not addressed ASAP. I pray everytime I have to go out and stop really far behind pumping and trying to make them work.
