Mazda cx-9 2011 has un-detected water pump leaks which cause to engine overheat and eventual engine death. Mazda corporate is unwilling to co-operate.

Brake booster failure, causing brakes to not engage without pumping the brake pedal. No check engine or maintenance lights were triggered due to the failure. Only indication was engine revving while idle for no apparent reason and inability to bring the vehicle to a stop.

I was driving about 40mph when I pressed on the brakes and it was hard and would not stop. I stepped on the brakes several times when it finally slowed down but it slowly rolled to a stop. After a few days of driving like this I knew to start breaking way in advance but now the car would suddenly turn off when at a complete stop while waiting at a red light. The whole engine would turn off and the engine light would turn on. I would turn the engine key off and then turn it on and the engine would turn on after the second try. I was freaking out every time if got into the car because I knew it would stop on me whenever I would stop at a long stop light. I finally took my car to a mazda service center and they said it was the brake booster. It's been 5months and my car is running great. I hope this is the end of this brake booster nightmare because it was a really scary experience.
