2011 MAZDA CX-9 Complaints

THE BRAKE PEDAL HAS BECOME EXTREMELY HARD AND IT DOESN'T STOP QUICKLY ANYMORE. IT FEELS LIKE THE BRAKES ARE GOING TO COMPLETELY FAIL AND NOT STOP THE CAR. A CAR IN FRONT OF ME SUDDENLY STOPPED TO MAKE A LEFT TURN AND AS I APPLIED MY BRAKES, THEY BECAME VERY HARD AND TOOK A VERY LONG TIME TO STOP, I ALMOST REAR ENDED THE CAR AHEAD OF ME. *TR

WHILE TRAVELING ON THE HIGHWAY RUSH HOUR TRAFFIC MY BRAKES STARTED MALFUNCTIONING. THE TRAFFIC AHEAD OF MY VEHICLE CAME TO A SUDDEN HALT. I APPLIED MY BRAKES (100 FT. FROM COLLISION), HOWEVER, THEY FAILED TO DECELERATE THE VEHICLE- IT DIDN'T FEEL AS THOUGH I HAD APPLIED THEM. IN ORDER TO PREVENT A COLLISION I DEPRESSED THE PEDDLE WITH ALL OF MY STRENGTH (60 FT. FROM COLLISION). GRADUALLY, AND INSUFFICIENTLY, THE CAR BEGAN TO DECELERATE. WITH THE BRAKE PEDDLE FULLY DEPRESSED. SUDDENLY (25 FT. FROM COLLISION) THE BRAKES TIGHTLY GRASPED THE ROTOR AND THE TIRES SCREECHED- THRUSTING THE PASSENGER AND I FORWARD. THEN THE BRAKED RELEASED AND GRASPED AGAIN.THE VEHICLE FINALLY STOPPED INCHES SHORT OF A COLLISION WITH THE AHEAD OF MINE. FOR THE PAST FEW DAYS, THE CAR HAS CONTINUED TO EXHIBIT SIMILAR SYMPTOMS. WHEN I FULLY DEPRESS THE BREAK THE VEHICLE MAKES A HISSING SOUND AND THE RPMS DROP- ON ONE OCCASION THIS ACTION CAUSED THE CUV TO SHUT OFF. I HAVE TO REMAIN AN ADDITIONAL 50 FT. BEHIND OTHER VEHICLES IN ORDER TO INSURE THAT I HAVE SUFFICIENT TIME TO STOP. *TR

THE BRAKES ON THE VEHICLE HAVE BECOME UNPREDICTABLE. I INITIALLY TOOK THE CAR TO MY LOCAL SHOP ONLY TO BE TURNED AROUND BEING TOLD THAT THERE WAS NOT ENOUGH WEAR ON THE PADS TO WARRANT REPLACEMENT AND THAT EVERYTHING LOOKED FINE. HOWEVER, BEING THE OWNER OF THE CAR, I CAN CONFIRM A SEVERE AND SUDDEN REGRESSION IN THE BREAKING BEHAVIOR. WHILE THE CAR STILL SLOWS DOWN WHEN THE BREAKS ARE APPLIED, THE PEDAL HAS BECOME VERY HARD AND THE ABILITY TO STOP SUDDENLY IS SEVERELY COMPRISED (EVEN AT A SLOW SPEED). I HAVE TO PLAN MY BRAKING POINT MUCH FURTHER AWAY FROM MY ANTICIPATED STOPPING POINT WHICH MAKES DRIVING MUCH TRICKIER. I WOULD NOT TRUST THE VEHICLE TO SAVE ME FROM A CRASH WERE I TO REQUIRE EMERGENCY BRAKING. *TR

MY SON AGE 13, WEIGHS 105 POUNDS. WHEN HE SITS IN THE FRONT PASSENGER SEAT THE AIR BAG WARNING LIGHT IS ILLUMINATED INDICATING THAT THE AIR BAG HAS BEEN DISABLED. IT IS MY UNDERSTANDING THAT THE RECOMMENDED MINIMUM AGE AND WEIGHT FOR THE FRONT SEAT IS 12 YEARS AND 80LBS RESPECTIVELY. THE MAZDA DEALER, (JOHN KENNEDY FORD, 1403 RIDGE PIKE, CONSHOHOCKEN, PA 19428) RAN A CHECK OF THE CALIBRATION OF AIRBAG SENSORS." ALL OK, NO UPDATE NEEDED" - THEY GAVE ME A COPY OF SERVICE BULLETIN NO 08-001/13. THIS MENTIONS THAT THE ISSUE IS CAUSED BY MY SON SITTING INCORRECTLY IN THE PASSENGER SEAT. I HAVE SPOKEN TO THE DEALER ON MULTIPLE OCCASIONS AND THIS ISSUE IS STILL NOT RESOLVED. *TR

I WAS DRIVING IN MY MAZDA 2011 CX9 SUV WHEN I PRESSED ON THE BRAKES AND THEY WOULD NOT ENGAGE. I HAD TO PRESS REPEATEDLY, EXTREMELY HARD IN ORDER TO GET THE VEHICLE TO STOP. I HAVE TAKEN THE CAR INTO MY MAZDA DEALER WHO IS SAYING THAT I HAVE A PROBLEM WITH THE MASTER CYLINDER LEAKING FLUID INTO THE BOOSTER. MAZDA HAS NOT SENT A RECALL FOR THE MASTER CYLINDER ONLY FOR THE BOOSTER. THIS IS A VERY DANGEROUS SITUATION AND ONE THAT NEEDS TO BE ADDRESSED BEFORE SOMEONE GETS INTO AN ACCIDENT. THIS CAR IS 2.5 YEARS OLD AND HAS 42000 MILES AND SHOULD NOT BE HAVING THESE PROBLEMS. MAZDA NEEDS TO HONOR THE REPAIR AND FIX THIS PROBLEM. *JS

BRAKES FAILED TO ENGAGE 3 TIMES THIS MORNING, THE FIRST TIME FAILED TO STOP THE SUV SO HAD TO SWERVE TO THE CENTER MEDIAN AND SLIGHTLY HIT THE METAL BARRIER. THEN GOING BACK HOME MAKING A TURN, BRAKES FAILED AGAIN TO ENGAGE. SEEMS THIS HAPPENED WHEN MAKING TURNS. BROUGHT TO THE MAZDA DEALER, TOLD THEM ABOUT ONGOING INVESTIGATION BY NHTSA ABOUT MAZDA CX9 2010-2011 BRAKE PROBLEMS. THEY DID A THOROUGH CHECK BUT COULD NOT DUPLICATE THE PROBLEM SO NOTHING WAS FIXED. IT MIGHT BE THE BRAKE BOOSTER. I'M AFRAID THIS MIGHT HAPPEN AGAIN, THEY SAID THERE WAS NO RECALL REGARDING BRAKES FOR 2011 MAZDA CX9. HOPE THAT NHTSA FORCES MAZDA TO MAKE A RECALL. MAZDA HAS TO FIX THIS DANGEROUS PROBLEM. *TR

OUR 2011 CX 9 BRAKES ARE FAILING. THE POWER BRAKE BOOSTER WILL AT TIMES NOT WORK MAKING THE BRAKES VERY HARD TO DEPRESS AND WITHOUT THE ABILITY TO QUICKLY AND SAFELY STOP THE CAR. *TR

MY WIFE COMPLAINED THAT THE BRAKES DIDN'T SEEM TO BE STOPPING THE VEHICLE VERY WELL. I DROVE THE CAR AND ALMOST HAD AN ACCIDENT. AT SLOW SPEED THE BRAKE PEDAL WAS VERY HARD TO DEPRESS AND MADE A HISSING SOUND, BUT CONTINUED TO TRAVEL SLOWLY TOWARD THE FLOOR. I LIMPED IT TO THE MAZDA DEALER AND I WAS TOLD THAT THE BOOSTER AND MASTER CYLINDER NEEDED TO BE REPLACED. WHEN I QUESTIONED THE SERVICE MANAGER ABOUT MAZDA'S PROBLEMS WITH CX-9 BRAKES, HE SAID MINE WAS THE FIRST ONE HE HAD HEARD OF. I DROVE AWAY AS FAST, CAREFULLY AND SAFELY AS I COULD. *TR

I HAVE NOT HAD A ACCIDENT YET, HOWEVER SINCE I PURCHASED THE CAR NEW I HAVE HAD TROUBLE WITH THE FRONT BRAKES, ESPECIALLY THE RIGHT WHEEL. THE DEALER SAY THERE IS NOTHING WRONG AND I HAVE COMPLAINED ABOUT THIS ISSUE SEVERAL TIMES AT REGULAR SERVICE. I KNOW SOMETHING IS WRONG, THE PEDAL FADES AND THERE IS A GRINDING AND SOMETIMES HISSING NOISE FROM THE FRONT RIGHT. IT NEEDS TO BE CORRECTED BY THE DEALER BEFORE SOMETHING REALLY BAD HAPPENS. *TR

I WAS DRIVING TO THE GROCERY STORE WITH MY TWO YEAR OLD AND MY SEVEN YEAR OLD. WHEN I APPLIED MY BRAKES AT A STOPLIGHT MY CAR DID NOT SLOW DOWN UNTIL I PUT BOTH FEET ON THE BRAKE PEDDLE AND PUSH WITH ALL MY MIGHT. THERE WAS NO WARNING LIGHT FOR A BRAKE PROBLEM. THE CAR WAS MAKING A HIGH PITCH SCREAMING NOISE WHEN I APPLIED THE BRAKE. MY FATHER WHO IS AN ENGINEER CHECK THE CAR AND FOUND THE BRAKE FLUID LOW AND IT HAD LEAKED INTO THE BOOSTER AND RUINED IT. I LOOKED ON LINE AND FOUND SEVERAL MAZDA OWNERS HAD REPORTED THE SAME PROBLEM. MY FAMILY, I AND ANYONE ELSE ON THE ROAD LIVES ARE IN DANGER IF THIS IS NOT RECALLED AND CORRECTED IMMEDIATELY. *TR
