Hissing Brake Investigation Closed After Warranty Extended

The 2010-2011 Mazda CX-9 was investigated by NHTSA earlier this year for brakes that weren't doing a great job at, well ... braking. Some owners even said the brake pedal would hiss when you stepped on it, kind of like my cat -- I don't think he likes me very much. Anyway ... that investigation was recently closed and the verdict? No recall.

It's not all bad news, however. Mazda identified the problem as a materials issue in the brake booster and is offering what they're calling a "special service program" which is just a fancy way of saying extended warranty.

The Mazda program will extend the warranty coverage for brake booster repairs to unlimited time and mileage if the repairs are performed between March 31, 2014 and March 31, 2015. If you miss that deadline and have the repairs done after March 31, 2015, the warranty is extended to 7 years or 90,000 miles.

In other words, if you ever feel like your 2010-11 CX-9 brake pedal is hard to push, feels spongy or hisses at you -- get it repaired, ideally before the end of March next year!
