What 221 owners told NHTSA about the 2012 Mazda Cx-90 Phev

WHEN BRAKING THE BRAKES ARE EITHER HARD AND DO NOT WORK OR BRAKES ARE SPONGY, WILL SLOW VEHICLE, BUT WILL NOT GIVE YOU CONFIDENCE THAT THEY WILL STOP THE VEHICLE LIKE THEY SHOULD. WHEN BRAKING AT TIMES YOU CAN HEAR A HISSING, MAYBE ALL THE TIME, BUT WHEN THINGS ARE HAPPENING YOU AREN'T LISTENING FOR A HISSING SOUND. ALSO, WHEN THE VEHICLE IS STATIONARY AND IN PARK IF YOU REALLY PUT YOU FOOT TO THE FLOOR A BEEPING ALMOST LIKE AN ALARM SOUND IS MADE. THIS BRAKE BOOSTER FAILURE SHOULD BE A MAJOR CONCERN. 8-13-2017 I WAS TRAVELING ABOUT 65 MPH IN LITE TRAFFIC ON A DOWNGRADE AND SLIGHT CORNER WHEN A VEHICLE IN FRONT OF ME LOST A TIRE AND I NEEDED TO BRAKE QUICKLY AND MY BRAKE PEDAL WOULDN'T MOVE, IT WAS HARD AS A ROCK, NEVER SLOWED THE VEHICLE AT ALL. THANK GOODNESS I HAD PLENTY OF ROOM TO MANEUVER, OTHERWISE WHO KNOWS WHAT THE RESULT OF THAT ACCIDENT MAY HAVE BEEN. ANOTHER TIME WAS 8-30-2017 I WAS DRIVING MY VEHICLE, APPROX 20 MPH, AND WAS APPROACHING THE INTERSECTION OF OUR SUBDIVISION AND THE HWY WHERE THE TRAFFIC TRAVELS AT 55 MPH, I WENT TO BRAKE AND THE PEDAL WENT TO THE FLOOR.... AGAIN NO BRAKES. MY VEHICLE ROLLED TO A COMPLETE STOP, BUT NOT BEFORE I CROSSED INTO THE SECOND LANE OF CROSS TRAFFIC. AGAIN THANK GOODNESS IT WAS AROUND 6:30 AM AND TRAFFIC WAS FAIRLY LITE. MIND YOU THIS IS ONLY TWO OF THE MORE EXTREME TIMES. I HAVE PURCHASED A NEW BRAKE BOOSTER AND IT WILL BE INSTALLED THIS WEEKEND. I DID TRY TO CONTACT MAZDA, BUT AFTER SITTING ON HOLD, 1-800-222-5500, FOR OVER 18 MINUTES THE PHONE FINALLY RINGS.....UNTIL IT DISCONNECTS.

WHEN STEPPING ON THE BRAKE PEDDLE A HISSING SOUND IS HEARD AND THE BRAKES NO LONGER STOP THE CAR.

NHTSA ODI 11013662

THE CAR BREAKS BECAME HARD TO PUSH STARTED HISSING AND WOULDN'T RESPOND TO BREAK TILL THE PEDAL WAS ALMOST PUSHED TO THE FLOOR. THERE WAS NO WARNING. WE WERE ON THE HIGHWAY.

NHTSA ODI 11003780

BRAKES HAVE BECOME VERY SQUISHY AND UNRESPONSIVE AND THERE IS A HISSING SOUND WHEN DEPRESSED. THIS IS A 2012 MAZDA BUT IT ONLY HAS 23.5K MILES ON IT. THIS HAPPENED ALL OF A SUDDEN AND WITHOUT WARNING AND MAKES THE VEHICLE VERY DANGEROUS TO DRIVE. IT IS BECOMING PROGRESSIVELY WORSE, WILL BE TAKING TO THE DEALERSHIP FOR REPAIR UNDER SUPPOSED EXTENDED WARRANTY.

NHTSA ODI 10994590

MY BRAKE BECOMES REALLY STIFF WHEN PUSHED. THIS SPECIALLY WHEN COMING TO A STOP WHERE YOU HAVE TO USE ALL YOUR ENERGY TO MAKE THE CAR STOP. MY WIFE USE THIS CAR WITH 2 YOUNG KID 5 AND 1 AND ONE ON THE WAY. THIS REALLY WORRIES ME SPECIALLY THAT ITS HAPPENING TO A LOT. IT MAY NOT SEEM A LOT TO MAZDA BUT ITS A LOT FOR THE CONSUMERS SPECIALLY WHEN LIVES ARE AT RISK. PLS FIX THIS PROBLEM BEFORE ITS TOO LATE . I WAS EVEN THINKING OF TRADING TO THE NEW 2017 MAZDA BUT NOW I HAVE DOUBTS

NHTSA ODI 10991904

TL* THE CONTACT OWNS A 2012 MAZDA CX-9. WHILE DRIVING VARIOUS SPEEDS, THE BRAKE PEDAL WAS DEPRESSED AND FAILED TO ENGAGE CORRECTLY. THE PEDAL FELT STIFF AND THERE WERE NO WARNING INDICATORS ILLUMINATED IN THE VEHICLE. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO DIAGNOSED THAT THE BRAKE BOOSTER WAS FAULTY AND THERE WAS A LEAK IN THE MASTER CYLINDER THAT NEEDED REPLACEMENT. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOTIFIED AND OPENED A CASE. THE VIN WAS INVALID. THE FAILURE MILEAGE WAS APPROXIMATELY 100,000.

NHTSA ODI 10990575

MY BREAK PEDAL FEELS AS IF IT BECOMES STIFF AND I HEAR A HISSING NOISE COMING FROM THE PEDAL. MY BREAKS WILL NOT SLOW THE VEHICLE. I HAVE TO REMOVE MY FOOT AND REAPPLY PRESSURE FORCEFULLY IN ORDER FOR THE BREAKS TO WORK. IT DOES THIS IN REVERSE, GOING DOWN AN INCLINE OR FLAT SURFACE. THIS HAPPENED WHILE MY CHILD WAS WITH ME. PLEASE REPUIREVA RECALL OR LIVES MAY BE AT STAKE.

NHTSA ODI 10985523

BRAKE PEDAL INTERMITTENTLY WILL NOT DEPRESS AND WILL NOT STOP THE CAR FROM GOING FORWARD. BRAKE RESERVOIR FULL. MULTIPLE TIMES DURING A SINGLE DRIVE. VERY UNSAFE.

NHTSA ODI 10984626

WITHOUT WARNING THE BRAKES BECAME SPONGY AND DIFFICULT TO DEPRESS THE PEDAL. STOPPING DISTANCE SIGNIFICANTLY INCREASED AND A HISSING NOISE WHILE BRAKES PEDAL DEPRESSED. TOOK IT IN FOR EVALUATION AND DIAGNOSED WITH BRAKE BOOSTER FAILURE.

NHTSA ODI 10983140

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.

NHTSA ODI 10979191

BRAKES ARE HARD TO PUSH. IT FEELS AS IF PRESSURE IS PUSHING UP AS I PUSH DOWN

NHTSA ODI 10971843

BRAKE PEDAL SUDDENLY BECAME VERY STIFF AND HARD TO DEPRESS. CAR WAS IN MOTION AND OCCURRED AS I WAS SLOWING DOWN FROM 30MPH TO 20MPH TO ENTER AN ACTIVE SCHOOL ZONE ON A RESIDENTIAL ROAD. AFTER COMING TO A STANDSTILL AND REPEATEDLY DEPRESSING THE BRAKE PEDAL A HISSING SOUND COULD BE HEARD EMANATING FROM THE BRAKE PEDAL AREA.

NHTSA ODI 10970553

UPON DRIVING MY VEHICLE, IT BECAME VERY DIFFICULT TO STOP AT ALL TIMES. I HAD TO USE BOTH FEET TO STOP AT A EMERGENCY STOP AND ALMOST HIT A CAR PULLING OUT IN TRAFFIC. THERE WAS NO STOPPING THIS VEHICLE USING THE BREAKS. I HAVE MY TWO SMALL CHILDREN THAT TRAVEL WITH ME, THIS PROBLEM WAS A HUGE THREAT TO THEIR SAFETY AND LIVES. THIS PROBLEM NEEDS TO BROUGHT TO THE ATTENTION OF OTHER DRIVERS BEFORE IT IS TOO LATE. BEFORE MY CAR CAUSED AN ACCIDENT, I BROUGHT IT TO MY MECHANIC AND HE TOLD ME IT WAS THE BREAK BOOSTER. HE ALSO TOLD ME THAT THIS SHOULD NOT BE HAPPENING CONSIDERING THE AGE AND MILEAGE ON MY VEHICLE. HE DID SOME RESEARCH AND FOUND SEVERAL COMPLAINTS RELATED TO THIS ISSUE, BUT NO RECALLS. WITH NO OTHER CHOICE I HAD HIM FIX THE PROBLEM. THIS IS A HUGE SAFETY PROBLEM AND SHOULD HAVE A RECALL. I WOULD LIKE TO BE REIMBURSED FOR THE MECHANIC I PAID TO FIX THE PROBLEM. IF IT WASN'T FOR THE DEFECT IN THE BREAK BOOSTER, I WOULDN'T HAVE HAD THIS PROBLEM IN THE FIRST PLACE. MY QUESTIONS TO YOU ARE, HOW MANY PEOPLE HAVE TO HAVE THEIR LIVES AND LOVED ONE'S LIVES PUT AT RISK IN ORDER FOR A RECALL TO BE ISSUED? IS IT CHEAPER TO HAVE A LAW SUIT OR TO ISSUE A RECALL?

I HAD TO PUSH HARDER AND HARDER ON MY MAZDA CX9 BRAKE PEDAL FOR MY CAR TO SLOWDOWN AND TO COME TO A COMPLETE STOP . THIS HAPPENED WHEN BACKING OUT OF MY GARAGE AND THE BRAKE IS GETTING WORSE EVERYDAY ON MY WAY TO WORK . ON THE DAY WHEN I HAD TO TAKE MY CAR TO THE MECHANICS , I HAD PRACTICALLY PUT BOTH FEET ON THE BRAKE PEDAL FOR THE CAR TO STOP . IT WAS A TERRIFYING EXPERIENCE THAT THE CAR WOULD NOT STOP AND CONTINUED TO ROLL FORWARD AND MORE SO AT EVERY TRAFFIC LIGHT . I TOOK MY CAR TO TWO DIFFERENT MECHANICS WITHIN ONE HOUR SINCE I DIDN'T BELIEVE THE FIRST ONE AND WANTED A SECOND OPINION . THEY BOTH TOLD ME THAT THE BRAKE BOOSTER AND THE MASTER CYLINDER WERE DEFECTIVE AND NEEDED TO REPLACE IMMEDIATELY BECAUSE I JUST DON'T HAVE BRAKE ON MY CAR ! THEY SAID THIS SHOULD NOT HAPPEN IN A CAR WITH ONLY 59,000 MILES . THE FIRST MECHANIC EVEN HAD ME SIGNED A WAIVER SINCE I DIDN'T WANT THEM TO FIX THE BRAKE AND WANTED A SECOND OPINION . I DID NOT BELIEVE THAT IT WOULD COST ME $1062,07 TO FIX THE BRAKE . UNFORTUNATELY THE SECOND MECHANIC GAVE ME THE SAME DIAGNOSTIC WITH THE COST OF $843 AND TWO DAYS TO ORDER THE PARTS SINCE IT WAS ON SATURDAY AND RECOMMENDED ME TO LEAVE THE CAR IN THEIR GARAGE . AND TO MAKE THE THING WORSE MY MAZDA DEALER SERVICE IS NOT OPEN ON THE WEEKEND . I GOOGLED AND FOUND OUT THAT THE DEFECTIVE BRAKE HAS HAD HAPPENED TO SEVERAL OTHER MAZDA CX 9 OWNERS AND NO RECALLS HAD EVER BEEN ISSUED . I DO HAVE PHOTOS OF THE DEFECTIVE BRAKE BOOST AND MASTER CYLINDER BUT DON'T KNOW HOW TO UPLOAD .

DROVE ~600 MILES WITH A FAILED BRAKE BOOSTER. FOUND OUT VIA INTERNET THAT MAZDA HAD PROVIDED AN EXTENDED WARRANTY TO COVER THIS DEFECT. WHEN THE DEALERSHIP WHERE I TOOK THE CAR TRIED TO FIND THE PART IT WAS ON BACKORDER WITH MAZDA. THE MAZDA SERVICE MANAGER AT PRESTON MAZDA, JOHN ROSENSTEEL, HAD ONE OF HIS PEOPLE DRIVE TO BUTLER, PA FROM BOARDMAN, OH TO PICK UP THE PART. I TOOK THE CAR TO THE DEALER ON THE DAY BEFORE THANKSGIVING AND THE CAR WAS READY TO GO WITH A NEW BOOST UNIT BY FRIDAY. THIS WAS ALL DUE TO THE EFFORTS OF AN EXCELLENT SERVICE MANAGER AT THE DEALERSHIP. MAZDA FAILED ME AS A CUSTOMER BY NOT HAVING THE BRAKE BOOSTER IN STOCK EVEN THOUGH IT WAS THE SUBJECT OF MULTIPLE FAILURES AND AN EXTENDED WARRANTY. *TR

WHILE BRAKING NORMALLY FOR A STOP SIGN, THE BRAKES BECAME HARD TO PRESS AND DID NOT STOP THE CAR AS NORMAL. HISSING FROM THE PEDAL AREA WAS HEARD AND THE CAR FINALLY STOPPED HALFWAY THROUGH AN INTERSECTION AFTER NEARLY STANDING ON THE BRAKES.

NHTSA ODI 10920085

BRAKES FELT HARD/STIFF AND VEHICLE DIDN'T STOP AS EXPECTED. ALMOST HIT ANOTHER CAR. HAD TO APPLY BRAKES MULTIPLE TIMES TO SLOW DOWN.

NHTSA ODI 10903891

LOSS OF BRAKE FLUID; BRAKE PEDAL HARD TO PUSH. UNABLE TO STOP CAR; HISSING NOISE AT BRAKE PEDAL.

NHTSA ODI 10899735

TL* THE CONTACT OWNS A 2012 MAZDA CX-9. WHILE DRIVING 20 MPH, THERE WAS A LOUD METAL TO METAL NOISE COMING FROM THE REAR OF THE VEHICLE. IN ADDITION, THE GEARS FAILED TO SHIFT CORRECTLY AND THE OIL AND ENGINE INDICATORS ILLUMINATED. THE DEALER DIAGNOSED THAT THE BRAKES NEEDED TO BE CHANGED. THE BRAKES WERE REPLACED, BUT THE FAILURE RECURRED AND WORSENED. THE CONTACT ALSO SMELLED FUEL COMING FROM THE VEHICLE AND THE VEHICLE HAD TROUBLE ACCELERATING. THE MANUFACTURER WAS NOTIFIED. THE FAILURE MILEAGE WAS 33,000.

NHTSA ODI 10899636

AT 44,000 MILES, BRAKES FEEL HARD AND VEHICLE BRAKES SLOWER THAN IT SHOULD WAS NEARLY IN AN ACCIDENT DUE TO THIS. IT TOOK A MUCH LONGER DISTANCE TO STOP. EMERGENCY REPAIR AT LOCAL SHOP INDICATED BRAKE BOOSTER FAILED. REALLY DANGEROUS SITUATION. MAZDA SHOULD RECALL

NHTSA ODI 10896239

BRAKE PEDAL BECAME SPONGY AND STOPPING POWER DIMINISHED CONSIDERABLY. HEARD A LOUD HISSING SOUND FROM THE FRONT DRIVER'S SIDE. HAD TO FULLY DEPRESS THE BRAKE PEDAL TO STOP QUICKLY.

NHTSA ODI 10894100

BRAKE BOOSTER - WHEN DEPRESSING THE BRAKES (ANY TIME OF DAY) THERE WAS A STRANGE HISSING NOISE, LIKE AIR BEING RELEASED FROM A BALLOON. IF THE PEDAL WAS PRESSED CLOSER TO THE FLOOR THERE WAS A HIGH PITCHED SQUEAL. BRAKES BECAME VERY HARD TO PRESS AND THE CAR BECAME EXTREMELY DIFFICULT TO STOP. LUCKILY THERE WERE NO CARD IN FRONT OF ME. A REPAIR SHOP INSTRUCTED ME TO CHECK BRAKE FLUID (WHICH WAS SLIGHTLY LOW, AND I FILLED IT). THIS DID NOT SOLVE THE PROBLEM. BRAKES ARE EVEN HARDER TO PRESS. FROM RESEARCH I SEE THAT MAZDA HAS HAD THIS PROBLEM FOR SOME YEARS NOW. THEY SHOULD RECALL THESE CARS AND REPLACE THE BOOSTERS BEFORE SOMEONE IS KILLED. WE HAVE FOUR KIDS IN OUR HOUSE AND THIS IS OUR ONLY TRANSPORTATION. THE CAR IS NO LONGER UNDER WARRANTY SO I WILL BE LEFT REPLACING THIS ON MY OWN.

NHTSA ODI 10893864

BREAKS SLOWLY STRTED TO GET HARFER TO PRESS , HERE AND THERE AND LAST FRIDAY WENT TO TAKE NY KIDS TO THE STORE AND A COUPLE NEIGHBORHOOD KIDS TAGED ALONG WHEN I GOT TO THE INTERSECTION MY BREAK PEDAL WOULD NOT PRESS DOWN SO THANKFULLY NO CARS WERE COMING AS I SLOW ROLLED THROUGH THE STOP SIGN ON A VERY BUSY FAST SPEED HIGWAY . CALLED MAZDA AND THEY SAID THEY HAVE HAD ISSUES . PLEASE IF U NOTICE ANY BREAK ISSUES GET THEM FIXED RIGHT AWAY THIS STORY COULD HAVE ENDED MUCH DIFFRENTLY WITH THE LOSS OF 5 KIDS KILLED BECAUSE THIS IS NOT A RECALL JUST A COMMON COMPLAINT AT THIS POINT IT WAS UNDER INVESTAGATION AT ONE POINT . MAZDA NEEDS TO STEP UP AND SEND LETTERS TO OWNERS OF THIS ISSUE .LET ME NOTE MAZDA WAS QIUCK TO GET IT N AND FIXED AND GAVE ME A RENTAL . THANK U FOR THAT BUT ALL I CAN THINK ABOUT IS HOW ALL THIS COULD HAVE ENDED .

NHTSA ODI 10892517

BRAKE BOOSTER - I HAD ISSUES PRESSING ON MY BRAKES, LIKE A BOOK HAD BEEN PLACED UNDERNEATH PREVENTING ME FROM FULLY APPLYING PRESSURE TO STOP MY VEHICLE. THIS HAPPENED WHEN I WOULD BACK OUT OF THE DRIVEWAY, GO DOWN THE HIGHWAY, AND IN TRAFFIC AS I SAT ON THE HIGHWAY. WHEN MY CAR WAS STATIONARY, I WOULD APPLY PRESSURE TO THE BRAKES AND COULD HEAR A VERY LOUD HISSING SOUND AS THOUGH SOMEONE WAS LETTING AIR OUT OF MY TIRES. LUCKILY I WASN'T IN AN ACCIDENT, HOWEVER, IT ALMOST HAPPENED ON A FEW OCCASIONS. WHEN I CALLED MAZDA TO HAVE MY CAR CHECKED OUT, I WAS TOLD THIS IS A COMMON PROBLEM THAT SEEMS TO HAPPEN WITH THE CX-9 AND I WAS ADVISED TO BRING MY CAR IN.

NHTSA ODI 10892055

THE BRAKE PEDAL ON THE MAZDA CX-9 BECAME VERY VERY HARD TO PUSH. ALSO, WHILE I WAS STOPPED COMPLETELY WITH THE BRAKE ALL THE WAY DOWN, THE BRAKE WOULD TEMPORARILY RELEASE ITSELF AND I HAD TO USE TWO FEET ON THE PEDAL TO GET THE CAR TO COMPLETELY STOP! THIS SHOULD WARRANT A COMPLETE RECALL AS I ALMOST DRIVE INTO BUSY INTERSECTIONS TWICE SO FAR!
