CX-9

  • Automatic transmission
  • 60,000 miles

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????
