In owners' own words
The contact owns a 2012 Mazda CX-9. While driving approximately 35 mph, the brake pedal was depressed and a loud squealing noise emitted. After applying the brake pedal numerous times, the vehicle came to a complete stop. The vehicle was towed to the dealer and currently being diagnosed. The manufacturer was not notified of the failure. The approximate failure mileage was 95,300. The vin was unavailable. Service brakes · reported at 95,300 miles
Brakes failed. Attempts to stop only slowed vehicle down unless extreme pressure applied. Pedal stopped halfway. Occasionally abs activated due to excessive force required to depress brake pedal. Repair with replaced brake booster. Immediately failed again by making noise on depression though vehicular is stopping. Dealer ordering another booster and will need to return for repair again when it comes in. Service brakes · reported at 35,060 miles
Just after shifting into drive from park, noticed high pitched squeal and hissing. Brakes had to be pressed all the way to floor in order to stop the vehicle at only 5-10 mph. Then while driving sometimes brakes seemed to work fine and other times needed to depress brake pedal all the way to floor. Seems to be an issue that should be recalled given so many people having such an issue at low mileage. Service brakes · reported at 45,100 miles
