2012 MAZDA CX-9 Complaints

AS I WAS DRIVING I NOTICED MY BRAKES MAKING A HISSING NOISE OF ABOUT DAY. THEN, THE BRAKE PEDAL BECAME HARD AND THEY FAILED TO WORK.

TL* THE CONTACT OWNS A 2012 MAZDA CX-9. THE CONTACT RECEIVED NOTIFICATION OF NHTSA CAMPAIGN NUMBER: 15V451000 (SUSPENSION); HOWEVER, THE PART TO DO THE REPAIR WAS UNAVAILABLE. THE CONTACT STATED THAT THE MANUFACTURER EXCEEDED A REASONABLE AMOUNT OF TIME FOR THE RECALL REPAIR. THE MANUFACTURER WAS MADE AWARE OF THE ISSUE. THE VIN WAS UNKNOWN. THE CONTACT HAD NOT EXPERIENCED A FAILURE.

BRAKES PREMATURELY FAILED AFTER FEELING NUMB AND SQUISHY. UPON DIAGNOSTIC BY A LOCAL MECHANIC, IT WAS DETERMINED THAT THE BRAKE MASTER CYLINDER HAD A LEAK. IN ADDITION, THE ABS, TRACTION CONTROL AND EMERGENCY BRAKE LIGHTS CAME ON WHEN THE SYMPTOMS WERE PRESENT. ESTIMATED COST OF REPAIR $1250.

CAR OF 3YR 8MTH < 40K MI. BRAKE NOT EFFECTIVE, FADE VERY QUICKLY, ATTEMPT TO LIFT AND REAPPLY BRAKE MAKES THING WORSE. HARDER TO BRAKE. HEAR HISSING NOISE, SIMILAR TO COMPLAINED BY OTHERS HERE. MAZDA NEEDS TO RECALL BEFORE SOMEONE GETS KILLED.

WHEN APPLYING BRAKES, BRAKES DO NOT STOP COMPLETELY. THERE IS A HISSING SOUND WHEN APPLYING BRAKES. BRAKES FEEL HARDER TO PRESS THAN USUAL.

WE EXPERIENCED WHAT SIMILAR MAZDA CX9 OWNERS HAVE REPORTED: OUR BRAKES STIFFENED, PROVIDED RESISTANCE COUPLED WITH A HISSING NOISE, AND FAILED TO STOP THE VEHICLE IN A TIMELY MANNER, DESPITE HAVING A FULL BRAKE FLUID RESERVOIR AND SUFFICIENT BRAKE PADS. OUR MECHANIC REPORTS FAILURE OF THE MASTER CYLINDER AND THE BLOWER. WE EXPERIENCED THESE EVENTS SUDDENLY AND WHILE THE CAR WAS IN MOTION.

BRAKE PEDAL GOT HARD VEHICLE WOULD NOT STOP NO WARNING LIGHTS ALMOST REAR ENDE VEHICLE BRAKE FAILURE

BRAKES MAKING HISSING SOUND AND THE CAR SUDDENLY STALLED WHILE WAITING ON A LIGHT. AFTER SOMETIME CAR STARTED BUT BRAKES WERE HARD AND HAD TO PRESS REALLY HARD FOR CAR TO STOP.

MY BRAKE FEELS LIKE IT HAS AIR UNDER IT AND IS HARD TO PRESS DOWN ON. IT ALSO MAKES A HISSING SOUND. WHEN STOPPED AT A TRAFFIC LIGHT, WITH MY FOOT ON THE BRAKE, IT FEELS LIKE MY CAR IS TRYING TO MOVE. I AM SCARED MY BRAKE WILL FAIL OR NOT WORK WHEN I PUSH ON IT. I NOTICED THIS ABOUT A WEEK AND A HALF AGO. I THOUGHT IT WAS NOTHING AT FIRST BUT IT IS STILL DOING THIS AND MORE FREQUENTLY. I AM CONCERNED THAT THIS WILL CAUSE AN ACCIDENT. I AM WORRIED SOMETHING WILL HAPPEN TO MY CHILDREN OR ME IF MY BRAKES FAIL BECAUSE OF THIS.

IN JUNE, I NOTICED THAT WHEN I STEPPED ON THE BRAKE PEDAL, IT WOULD MAKE A HISSING SOUND, LIKE AIR BEING RELEASED FROM A TIRE. RECENTLY, THE BRAKE PEDAL FEELS SOFT AND I HAVE TO STEP ON IT ALL THE WAY FOR THE CAR TO SLOWLY SLOWDOWN. BEEN IN VERY CLOSE SITUATIONS RECENTLY. I CHECKED THE BRAKE FLUID AND IT WAS LOW, SO I REFILLED IT AND TOOK IT OUT FOR A DRIVE... THIS DID VERY LITTLE. THE BRAKE PEDAL STILL MAKES A HISSING SOUND AND FEELS VERY SPONGY. IT IS NOW MAKING A BRAND NEW SOUND TOO. WHEN I STEP ON THE BRAKE PEDAL ALL THE WAY, IT MAKES A WHISTLING SOUND. VERY HIGH PITCH WHISTLING SOUND LIKE A LOT OF AIR IS TRYING TO SQUEEZE OUT OF A TINY HOLE. IF THIS IS A COMMON PROBLEM, THEY NEED TO GET THIS CAR RECALLED BECAUSE I USE IT TO TRANSPORT MY LITTLE ONES AROUND.
