2011 MAZDA CX-9 Complaints

WHEN PRESSING THE BRAKES AT ANY SPEED THERE WAS A HISSING SOUND AND THE BRAKES WERE HARD TO PRESS. REGARDLESS OF THE AMOUNT OF PRESSURE I APPLIED TO THE BRAKES THEY DID NOT REACT AND IT TOOK THE VEHICLE LONGER TO SLOW DOWN EVEN AT VERY LOW SPEEDS (5-10 MPH) OR FASTER. THIS CAME ON SUDDENLY AND CAUSED ME TO BRING THE VEHICLE INTO THE SERVICE DEPARTMENT OF THE THE DEALERSHIP WHERE I PURCHASED IT. THE MAZDA TECHNICIAN INSPECTED THE VEHICLES AND COMPLETED A DIAGNOSTICS OF THE VEHICLE AND DISCOVERED THAT THE MASTER CYLINDER AND BRAKE BOOSTER HAVE FAILED AND NEED TO BE REPLACED.

THE POWER STEERING ASSIST FAILED AND IT WAS IMPOSSIBLE TO BACK THE CAR OUT OF A PARKING SPACE. AFTER MOVING THE CAR BACK AND FORTH AND SLIGHTLY TURNING THE STEERING WHEEL THE POWER ASSIST CAME BACK. IT IS IMPOSSIBLE TO MAKE A TURN WITHOUT THE POWER ASSIST. THIS PROBLEM PERSISTS AND HAPPENS AT LOW SPEED OR WHEN I AM STOPPED AND TRYING TO MAKE A TURN. AS LONG AS I AM MOVING THE POWER ASSIST SEEMS TO WORK.

ON 24 JULY 2015, WHILE DRIVING HOME FROM WORK, THE DRIVER IN FRONT OF ME EXECUTED AN EMERGENCY BRAKING TO AVOID A COLLISION WHICH CAUSED ME TO DO THE SAME. FROM THE MOMENT I TRIED TO ACTUATE THE BRAKE PEDAL, IT FELT AS IF THE PEDAL WAS IN THE FLOOR AND IMMOVABLE. LITTLE, IF ANY, BRAKE FORCE WAS APPLIED AND REQUIRED BOTH FEET WITH ALL THE POWER OF MY LEGS TO GET EVEN A SMALL AMOUNT OF BRAKING. I HAD TO IMMEDIATELY DIVE INTO THE MEDIAN AT SPEEDS OF 60-65 MPH TO AVOID HITTING THE CAR IN FRONT OF ME. THIS CAUSED TWO TIRES TO HAVE TO BE REPLACED. WHEN I LEFT MY PARKING GARAGE AND ALL THE WAY TO THE FREEWAY, BRAKING WAS NORMAL. NO DASH LIGHTS WERE ACTIVE NOR ARE THEY NOW. THE ISSUE PERSISTS NOW AND DRIVING THE VEHICLE IS NOT AN OPTION.

BRAKE PEDAL IS VERY HARD TO PUSH IN. TRIED TO STOP AT A LIGHT AND THE BRAKES WOULDN'T STOP THE CAR, LUCKILY THERE WAS'T SOMEONE IN FRONT OF ME. BRAKES FEEL LIKE I AM PUSHING AGAINST A WALL, ALSO CAN HEAR A HISSING OR LEAKING SOUND WHEN I TRY TO PUSH THE BRAKES.

THE BRAKES DID NOT RESPOND TO TYPICAL PRESSURE REQUIRED TO STOP... WHEN I PUSHED HARDER ON THE BRAKE PEDAL IT FELT LIKE THE BRAKES WERE STARTING TO ENGAGE, HOWEVER I COULD NOT GET THEM TO FULLY ENGAGE AND STOP IN TIME TO AVOID REAR ENDING THE VEHICLE IN FRONT OF ME. I TOOK EVASIVE ACTION AND JUMPED THE CURB AND DIRECTED THE VEHICLE AT BANK OF NEWSPAPER STANDS IN ORDER TO COME TO A COMPLETE STOP.

I HAVE BEEN HAVING ISSUES WITH THE BRAKES MOSTLY WHEN RAINING OR SNOW. AT TIMES WHEN I GO TO HIT THE BRAKES THEY GET STUCK OR MAKE A GRINDING NOISE AND DON'T WANT TO STOP. THIS HAS HAPPENED NUMEROUS TIMES AND ALMOST CAUSED ME TO HIT ANOTHER CAR ON MULTIPLE OCCASIONS. I WILL TAKE IT IN SOON TO HAVE IT CHECKED NOW THAT I SEE THAT I AM NOT THE ONLY PERSON WITH THIS ISSUE. STARTING IN JAN 2015 I NOTICE A BURNING SMELL COMING FROM UNDER THE HOOD OF THE CAR. I HAD AN OIL CHANGE AND CHECKED FOR AN OIL LEAK TO FIND NOTHING WRONG WITH THE VEHICLE. AFTER RUNNING THE CAR FOR AT LEAST 20 MINUTES THE SMELL CONTINUES.

VEHICLE WOULD NOT SLOW OR STOP, HAD TO PUSH PEDAL HARD ALL THE WAY TO THE FLOOR TO GET IT SLOWED. REALLY THOUGHT WE WERE GOING TO HAVE AN ACCIDENT. TOOK VEHICLE INTO SHOP ON 6/5/2015 AND WAS TOLD IT WAS THE POWER BRAKE ASSIST MODULE WAS BAD AND NEEDED TO BE REPLACED. OWNER OF SHOP SAID WE WERE LUCKY TO NOT HAVE BEEN IN AN ACCIDENT. COME ON MAZDA YOU ARE AWARE OF THIS SITUATION.

I HAD 3 CHILDREN IN CAR SEATS, MYSELF AND MY OLDEST SON IN OUR CX9. I CRESTED A HILL AND STARTED DOWN THE OTHER SIDE AND I APPLIED THE BRAKES TO SLOW DOWN AND THEY WERE HARD AND WOULD NOT ALLOW ME TO STOP. I ALMOST HIT THE TRUCK IN FRONT OF ME. HE WAS THANKFULLY WATCHING HIS MIRROR AND RAN A RED LIGHT TO GET OUT OF THE WAY SO I DIDN'T HIT HIM. AFTER STANDING ON THE BRAKES FOR WHAT SEEMED LIKE A LIFE TIME THEY FINALLY ENGAGED IN THE MIDDLE OF THE INTERSECTION AND HISSED WITH A LOUD SQUEALING NOISE. I REMOVED MYSELF FROM THE INTERSECTION AND AT 5 MILES PER HOUR WENT TO THE NEAREST MECHANIC. I WAS TOLD TO CALL MAZDA BECAUSE THE POWER ASSIST BRAKING SYSTEM HAD FAILED. I CALLED MAZDA AND THEY TOLD ME NOT DRIVE IT AS IT WAS UNSAFE. THEY WOULD HAVE IT TOWED TO THE NEAREST DEALERSHIP AND WOULD TAKE CARE OF IT. THE NEAREST DEALERSHIP IS DOLAN MAZDA KIA IN RENO NEVADA. I WAS INFORMED BY STEVE TO LOOK AT IT IN THE SHOP I WAS LOOKING AT $125. AND THAT IT WAS NO LONGER UNDER WARRANTY BECAUSE MY CX9 HAS OVER A 100K MLS. AND THE WARRANTY RAN OUT AT 90K. THE BRAKES FAILED UNEXPECTEDLY WITH NO WARNING. I WAS NEVER NOTIFIED ABOUT THIS SAFETY ISSUE FROM MAZDA NOR THE DEALERSHIP I PURCHASED IT FROM. I SEE THAT THE NHTSA HAS CLOSED IT'S INVESTIGATION WITH NO RECALL OR THAT MAZDA CUSTOMERS WERE INFORMED. MY FAMILY COULD HAVE BEEN SERIOUSLY INJURED OR EVEN KILLED.
