2011 MAZDA CX-9 Complaints

BRAKE PEDAL BECAME INCREASING HARD TO DEPRESS REQUIRING AN EXCESSIVE AMOUNT OF FORCE TO ENGAGE BRAKES. STOPPING POWER DECREASED AND DISTANCE TO A FULL STOP INCREASED LEADING TO VERY DANGEROUS SITUATIONS WHEN DRIVING THE VEHICLE. MECHANIC SAYS THE BRAKE BOOSTER NEEDS TO BE REPLACED. *TR

I WAS DRIVING MY SON TO THE DOCTORS OFFICE WHEN I REALIZED THE BRAKES DID NOT FEEL RIGHT. I TOLD MY HUSBAND THAT I FELT A LOT OF RESISTANCE WHEN APPLYING THE BRAKES. SO WHEN I GOT HOME I HAD MY HUSBAND DRIVE THE CAR AND HE SAID HE DID NOT FEEL ANYTHING UNTIL LATER THAT NIGHT WHEN HE WAS DRIVING THE VEHICLE HE FREAKED OUT CAUSE HE SAID HE FELT AS IF THE CAR WASN'T GOING TO STOP AFTER PUSHING ON THE BRAKES. HE HAD TO PULL OFF OF THE HIGHWAY AND TAKE THE BACK ROADS HOME AT A LOW SPEED AND GIVE HIMSELF PLENTY OF DISTANCE FROM THE CAR IN FRONT OF HIM IN ORDER TO BRAKE SO HE WOULD NOT SLAM INTO THEIR CAR. ALSO, WHEN APPLYING ALL THE PRESSURE YOU COULD TO THE BRAKES, A LOUD HISSING SOUND COULD BE HEARD AS WELL. THE CAR WAS TAKEN TO OUR MAZDA DEALER WHERE THE CAR WAS PURCHASED AND AFTER THEY LOOKED AT IT, WE WERE TOLD THAT THE VEHICLE HAD BAD BRAKE BOOSTERS AND THAT WE WERE LUCKY WE WEREN'T IN AN ACCIDENT. AFTER HEARING THIS AND RESEARCHING IT, IT REALLY UPSET US THAT MAZDA HAS HAD THIS ISSUE WITH THE SAME MODEL VEHICLE OF OTHER YEARS.... WHY HASN'T A RECALL BEEN DONE? ARE THEY WAITING FOR SOMEONE TO LOSE THEIR LIFE BEFORE SOMETHING IS DONE?! I THANK GOD WE WERE ABLE TO STOP OUR CAR BUT THERE WAS NO WARNING OR LEAD UP TO THIS INCIDENT. IT LITERALLY JUST HAPPENED OUT OF NOWHERE! *TR

AUGUST 6TH 2013 MY WIFE COMPLAINED ABOUT THE BRAKES ON HER 2011 MAZDA CX9 MAKING A HISSING TYPE SOUND AND BRAKES FEELING MUSHY AND NOT RESPONDING AS NORMAL. THE NEXT DAY SHE ADVISED THE BRAKES WERE WORSE SO WE PARKED THE CAR UNTIL THE 9TH. THE CX9 HAS 46000. MILES. THE CAR RECEIVES REGULAR MAINTENANCE AND WAS TAKEN TO TOM BUSH MAZDA (JACKSONVILLE FL.) FOR DIAGNOSIS OF THE PROBLEM. WE WERE ADVISED THAT THE ISSUE WAS A VACUUM LEAK FROM THE BRAKE BOOSTER AND IT HAD TO BE REPAIRED AT THE COST OF $695.88. (PART = $130. W/ LABOR $503.) WE LEARNED THAT OTHERS HAVE HAD THE SAME PROBLEM AND THAT A RECALL MIGHT HAVE BEEN ISSUED FOR THE PREVIOUS YEAR CX9S. THERE WAS NO CONSIDERATION ON REPAIR COSTS. OUR ISSUE IS THE BRAKE VACUUM BOOSTER FAILURE SEEMS TO BE AN ABNORMALLY COMMON COMPLAINT ON MAZDA'S CX9 VEHICLES AND THE FACT THAT THIS INVOLVES BRAKE FAILURES, IS A SAFETY ISSUE THAT MAY LEAD TO A CATASTROPHIC CRASH AT HIGHER SPEEDS. I BELIEVE OTHER SIMILAR COMPLAINTS NOTED ABOUT MAZDA CX9 BRAKE ISSUES IN THE NHTSA WARRANT A THOROUGH INVESTIGATION AND POSSIBLE RECALL. WE WILL RETAIN THE DEFECTIVE PART. FURTHER NOTE, THE MAZDA DEALERSHIP RELEASED THE VEHICLE TO MY FATHER W/O PROPERLY INSPECTING THEIR WORK. THE VEHICLE WAS RELEASED TO US W/O THE BRAKE LINES BEING BLED PROPERLY WHICH CAUSED THE BRAKES TO FAIL WHILE AT THE DEALERSHIP. IT TOOK ANOTHER DAY TO FIX THAT ISSUE. *TR

SIMILAR TO OTHER COMPLAINTS HERE, I RECENTLY STARTED NOTICING HISSING WHEN I PRESSED MY BRAKES....... I NOTICED THAT I WAS HAVING A HARD TIME COMING TO A COMPLETE STOP. I TOOK MY CX9 IN TODAY AUGUST 14, 2013 TO GUNTHER MAZDA IN FORT LAUDERDALE. I THOUGHT IT WAS GOING TO BE A SIMPLE CHANGE OF BRAKE PADS, LITTLE DID I KNOW I WAS IN FOR $700!!!!!- APPARENTLY THIS IS NOTHING NEW FOR MAZDA, THERE WAS AN INVESTIGATION GOING ON BY THE NHTSA FOR THE 2008 CX9 MODEL AND GUESS WHAT? THE 2011 SEEMS TO BE HAVING THE SAME EXACT ISSUE. THE MECHANIC SAID THE PADS ARE FINE BUT THE MASTER CYLINDER AND BOOSTER NEED TO BE REPLACED. I'M GOING TO CALL MAZDA USA TO SEE WHAT THEY CAN DO BUT UNLESS EVERYONE STARTS DEMANDING ANSWERS THEY'RE GOING TO BE LAUGHING ALL THE WAY TO THE BANK. IT'LL TAKE A STRONG EFFORT TO MAKE THEM ISSUE A RECALL. THIS IS MY LAST MAZDA. I'M GOING BACK TO MY LEXUS, MORE EXPENSIVE BY A LOT BUT I DIDN'T HAVE TO WORRY ABOUT PUTTING MY LIFE AND MY DAUGHTER'S LIFE AT RISK. THIS IS RIDICULOUS. *TR

I JUST STATED NOTICING ISSUES WITH MY BRAKES, I STARTED HEARING A LOW HISSING NOISE AND NOTICED THAT I WAS HAVING A HARD TIME COMING TO A COMPLETE STOP. I NEED TO PUMP THE BRAKES SEVERAL TIMES TO SLOW DOWN AND THEN ONCE STOPPED THE BRAKES GO ALL THE WAY TO THE FLOOR. I TOOK MY CX9 IN TODAY JULY 8, 2013 TO HAVE THE BRAKES CHECKED AND THE OIL CHANGED. I WAS TOLD THE BREAKS AND PADS ARE FINE BUT THERE IS SOMETHING WRONG WITH THE BRAKES. THEY TRIED FLUSHING THE LINES AND THAT DID NOT HELP. THEY TOLD ME THEY COULD NOT LOOK AT THE CAR FURTHER UNTIL WEDNESDAY JULY 10TH. I ASKED IF THE CAR WAS SAFE TO DRIVE THEY SAID IT WAS AND TO GO SLOWLY UPON REACHING A LIGHT AND MAKE SURE TO PUMP THE BREAKS SO I CAN STOP IN TIME AND NOT GO THROUGH THE INTERSECTION. THIS IS VERY ALARMING TO ME SINCE AN ACCIDENT CAN OCCUR THIS IS MY ONLY VEHICLE AND I NEED TO GET BACK AND FORTH TO WORK. THEY TOLD ME THEY NEEDED TO CALL THE MAZDA HELP LINE TO FIND OUT WHAT IS WRONG WITH THE BREAKS. AFTER RESEARCHING ON LINE TODAY MAZDA CX9 BRAKE ISSUES AM VERY INTERESTED TO SEE WHAT THEY SAY AND IF IT IS THE SAME PROBLEM THAT HAS BEEN REPORTED SINCE 2008 WITH THIS MODEL. I AM VERY UPSET SINCE I TAKE VERY GOOD CARE OF MY CAR AND ALWAYS TAKE IT TO THE MAZDA DEALER FOR SERVICE. MY VEHICLE IS AT THE 37,000 MARK WHICH APPEARS TO BE THE POINT WHEN THIS HAS BEEN A PROBLEM FOR OTHER VEHICLES. I HOPE THAT MAZDA WILL COVER THE COSTS TO FIX THE CAR AND THAT I DON'T GET INTO AN ACCIDENT BETWEEN NOW AND WEDNESDAY. *TR

2011 MAZDA CX-9. CONSUMER WRITES IN REGARDS TO VEHICLE FIRE CAUSED BY TRANSMISSION/TRANSFER CASE FAILURE. *SMD THE CONSUMER STATED THE BOTTOM OF THE VEHICLE CAUGHT ON FIRE, IT WAS PUT OUT BEFORE ANY EXCESSIVE DAMAGE WAS DONE. THE CONSUMER STATED PRIOR TO THE FIRE, THE VEHICLE STARTED VIBRATING AND WHEN SHE ATTEMPTED TO DRIVE, IT WOULD NOT MOVE.

TL* THE CONTACT OWNS A 2011 MAZDA CX-9. THE CONTACT STATED THAT THERE WERE FUEL FUMES INSIDE THE CABIN OF THE VEHICLE. ADDITIONALLY, THE CONTACT WAS DRIVING 20 MPH WHEN THE VEHICLE BEGAN TO DECELERATE INDEPENDENTLY AND STALLED. THE VEHICLE WAS TAKEN TO THE DEALER, WHO DETERMINED THAT THE TRANSFER CASE WAS CRACKED AND SEIZED. THE FAILURE WAS NOT REPORTED TO THE MANUFACTURER. THE VIN WAS NOT AVAILABLE. THE FAILURE AND CURRENT MILEAGE WAS 36,300. UPDATED 07/30/13*LJ THE DEALER REPLACED THE TRANSFER CASE. UPDATED 08/01/13

UPON LIGHT BRAKING I HEAR A HISSING SOUND. THE BRAKES ARE INEFFECTIVE AT SLOW SPEEDS. IT TAKES A LONGER TIME AND REQUIRES APPLICATION OF GREATER BRAKING FORCE TO GET THE CAR TO COME TO A COMPLETE STOP. I TOOK THE CAR IN FOR INSPECTION AND AM AWAITING THE RESULTS. I SAW ONLINE THAT THERE ARE KNOWN PROBLEMS WITH THE BRAKING SYSTEM. *TR

APPROACHING A RED LIGHT ON A DRY SUNNY DAY, MY BRAKES FAILED HALFWAY THROUGH COMING TO A STOP. AT FIRST MY VEHICLE (2011 MAZDA CX-9 SPORT WITH 56,000 MILES) WAS SLOWING DOWN NORMALLY AND THEN SUDDENLY THERE WAS GRINDING/CRUNCHING NOISES AND DESPITE PRESSING THE BRAKE, THE VEHICLE WAS NO LONGER STOPPING. I SLAMMED THE BRAKES, PUMPED A FEW TIMES, AND THE VEHICLE SIMPLY FAILED TO SLOW DOWN OR STOP CAUSING ME TO SLAM INTO THE REAR OF THE VEHICLE IN FRONT OF ME. I TOOK THE CAR INTO A MECHANIC WHO NOTIFIED ME THAT BOTH OF MY "FRONT CALIPERS WERE POSSIBLY DEFECTIVE," AND MY FRONT ROTORS WERE "UNEVEN AND WEARING ON THE OUTSIDE." HOWEVER, MY BRAKE PADS WERE GOOD AND DID NOT NEED TO BE REPLACED. GOOD THING I WAS ALREADY STOPPING FOR THE RED LIGHT; THEREFORE I ESTIMATE GOING ABOUT 10-15 MPH (SPEED LIMIT ON STREET WAS 35 AND I WAS ALREADY MIDWAY THROUGH COMING TO A STOP AT THE LIGHT). IMAGINE IF I NEED TO BRAKE WHILE GOING 60-70 MPH ON THE INTERSTATE! OR WORSE, DRIVING IN THE RAIN! *TR

ATTEMPTED TO LATCH THE DRIVER SEATBELT, BUT THE LATCH WOULD NOT RECEIVE THE BELT. AFTER SEVERAL ATTEMPTS TO LATCH THE BELT BY INSERTING IT INTO THE LATCH MECHANISM, I WAS ABLE TO LATCH THE BELT BY FIRST PUSHING DOWN THE RELEASE MECHANISM; THEN INSERTING THE BELT. THIS HAS TO BE DONE EACH TIME IN ORDER THE LATCH THE DRIVER SIDE SEATBELT. NO OTHER SEATBELTS ARE AFFECTED. THIS CAR HAS BEEN SCHEDULED INTO BOMMARITO MAZDA FOR RESOLUTION OF THIS PROBLEM. *TR
