I have a 2008 Mazda cx9, I got it 1yr ago. There was a brake problem, then and I had pads and rotors changed. It's been 1yr since I did that and out of nowhere I noticed something was wrong while driving. When I pressed on the brake, I would hear a hissing sound nd my pedal would release to the floor and a whining noise. I changed all my brakes, then while I was driving a came to a red light went to stop and the brake pedal barely moved. I almost slammed into the vehicle in front of me because I COULD NOT STOP. I had my car towed to a certified mechanics shop and found out that my booster stopped working. Why doesn't Mazda help this situation, looks like this is a big problem.

  • Automatic transmission

I'm so annoyed because my car's year doesn't appear to be included in the federal investigation that took place regarding problems with the power brake booster. But that's just one issue. The second issue, and really a bigger problem is the wait for parts. The part has to be shipped in from a Mazda dealership in some other state because there is not one of these items in the whole of California. WTF? This is the second time Mazda had no parts - actually last time, THERE WERE NO PARTS IN THE ENTIRE COUNTRY, ACTUALLY THE WORLD. WE HAD TO WAIT FOR A NEW COMPUTER TO BE MANUFACTURED AND DELIVERED FROM CHINA!!!!!. This cost me about $600 in rental car fees. WTH Mazda? I see CX-9's all over the damn place - why don't you maintain a reasonable supply of accessible parts????
