2012 MAZDA CX-9 Complaints

ATTEMPTING TO STOP THE VEHICLE AT A RED LIGHT, BRAKE PEDAL WAS HARD TO PUSH, INCREASING THE DISTANCE REQUIRED TO STOP THE VEHICLE. THIS HAS HAPPENED MULTIPLE TIMES, ALONG WITH A HISSING SOUND COMING FROM THE DRIVERS SIDE OF THE VEHICLE WHEN THE BRAKE PEDAL IS DEPRESSED. WE ARE STILL HAVING PROBLEMS WITH THE BRAKES AND HAVE SCHEDULED A SERVICE WITH MAZDA. *JS

WHILE I WAS DRIVING THIS SUV WITH MY FAMILY( WIFE, 4 YEAR OLD SON, 2 YR OLD DAUGHTER), BREAKS WERE STICKY AND NOT APPLIED. I WAS ABOUT TO HIT ACROSS THE VEHICLE BUT LUCKILY I STOPPED BY USING EMERGENCY BREAKS AND MOVING SHIFT ROD TO L. I SPOKE TO MAZDA DEALER AND HE TOLD ME THAT IT IS A BREAK DEFECT AND MAZDA WILL COVER FOR IT. THIS IS VERY SERIOUS INCIDENT AND DO NOT WANT TO HAPPEN TO OTHERS. BY GOD GRACE WE SURVIVED. I CAN FEEL MY DEATH DURING THAT TIME. THANKS [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

BRAKES PEDAL BECOMES HARD AND EITHER IMPOSSIBLE TO PUSH OR GOES ONLY HALF-WAY DOWN. AS A RESULT CAR DOESN'T COME TO A FULL STOP. THIS HAPPENED AT LEAST 3 TIMES DURING LAST WEEK, UNTIL I TOOK IT TO A DEALERSHIP AND THEY REPLACED THE BRAKE BOOSTER. I FOUND THAT THIS IS KNOWN ISSUE FOR 2010 AND 2011 VEHICLES AND THERE WAS AN INVESTIGATION ABOUT IT AND INVESTIGATION WAS CLOSED AROUND JULY 2014 WITHOUT ANY RECALLS. BUT SEEMS LIKE THE SAME PROBLEM EXISTS FOR 2012 MODELS AS WELL AND MAZDA DIDN'T FIX IT ON NEWER MODELS. *TR

FOR THE PAST WEEK, MY 2012 MAZDA CX-9 HAS BEEN HAVING ISSUES WITH NOT BRAKING. AT FIRST, I THOUGHT IT WAS JUST MY IMAGINATION, BUT EVERY DAY THIS PAS WEEK, AT LEAST ONCE A DAY, I GO TO PUSH ON THE BRAKE PEDAL AND IT WON'T MOVE. THE BRAKE PEDAL IS STIFF AS IF I'M PUSHING ON A BLOCK OF CEMENT. IT'S VERY SCARY, AND I'VE ALMOST HIT SEVERAL CARS, AND EVEN ALMOST HIT A PEDESTRIAN. I AM A MOM AND DRIVE WITH MY SMALL CHILDREN IN THE CAR OFTEN. THAT'S WHY I BOUGHT A FAMILY VEHICLE. TODAY I WAS AT A DRIVE THRU WINDOW, AND THE CAR STALLED COMPLETELY. I TURNED THE IGNITION, AND IT STARTED UP, BUT THE ENGINE WAS SHAKY, NOT IDLING RIGHT. IT FELT LIKE IT WOULD STALL AGAIN AT ANY MOMENT. I CALLED MAZDA, BUT MY CAR HAS 40K MILES, AND THEY WERE VERY RUDE AND SAID MY WARRANTY EXPIRED AT 36K MILES. I TOOK IT TO OUR FAMILY FRIEND WHO IS A MECHANIC, AND WHEN I TOLD HIM ABOUT THE BRAKE PROBLEM AND THE STALLING, HE SAID HE KNEW EXACTLY WHAT WAS WRONG. THERE WAS A LEAK IN THE VACUUM SYSTEM ON THE BRAKE BOOSTER, AND THE STALL AND THE BRAKE PROBLEM ARE BOTH CAUSED BY THAT. I WENT ONLINE AND DID RESEARCH, AND FOUND THIS SITE, AND THAT OTHERS ARE HAVING THIS PROBLEM. I CALLED MAZDA BACK AND GOT HE SAME RUDE SERVICE GUY. I EXPLAINED WHAT I HAD FOUND ON THIS SITE, AND HE SAID, WELL THIS MORNING WHEN YOU CALLED, YOU ONLY TOLD ME ABOUT THE STALL, YOU DIDN'T TELL ME YOU WERE HAVING BRAKING PROBLEMS. HE ACKNOWLEDGED THAT THERE WAS A PROBLEM WITH THE BRAKE BOOSTER AND CHECKED MY VIN TO BE SURE MY CAR WAS COVERED UNDER THE NEWLY EXTENDED WARRANTY ON THE BRAKE BOOSTER. I'M TAKING IT IN TOMORROW FOR THEM TO REPAIR IT FREE OF CHARGE. THIS IS EXTREMELY SCARY AND I HOPE THE NHTSA WILL DO A RECALL ON THIS!!! MYSELF OR MY FAMILY COULD HAVE BEEN SEVERELY INJURED IN AN ACCIDENT, OR I COULD HAVE INJURED SOMEONE ELSE!!! *TR

LIKE ONE OTHER INCIDENT, MY COMPLAINT INVOLVES THE TRANSFER CASE WHICH IS SPECIFIC TO THE AWD MODELS. I WAS ON A MAJOR ROADWAY WHEN I NOTICED A LOW, STRANGE NOISE. ABOUT THIS TIME I WAS PREPARING TO ENTER A TURN LANE WHEN THE CAR SUDDENLY LURCHED AND MADE AN AWFUL NOISE THAT LITERALLY SOUNDED LIKE THE ENGINE FELL OUT. IT THEN FELT LIKE I RAN OVER SAID ENGINE BEFORE THE CAR CAME TO AN ABRUPT STOP. THANKFULLY THE LIGHT AT THE INTERSECTION HAD BEEN RED AND TRAFFIC WAS SLOWING WITH ME BECAUSE I SHUDDER AT THE THOUGHT IF TRAFFIC HAD BEEN MOVING AT THE REGULAR RATE OF SPEED. MAZDA ROADSIDE ASSISTANCE HAD IT TOWED TO THE DEALERSHIP WHERE THE TWO GUYS IMMEDIATELY ASKED IF IT WAS AN AWD MODEL. THEY SAID THAT WITHOUT EVEN LOOKING AT IT, BASED ON WHAT I'D SAID HAPPENED, THEY'D BET IT WAS THE TRANSFER CASE. THANKFULLY THE TC WAS STILL UNDER THE POWER TRAIN WARRANTY, BUT IT SEEMS LIKE MAZDA IS AWARE OF THIS ISSUE. WOULD HAVE SERIOUSLY BEEN NICE TO BE ALERTED TO SUCH A POTENTIALLY DANGEROUS DEFECT. I WOULD HAVE CERTAINLY HAD MINE REPLACED TO AVOID BEING PUT INTO THE SITUATION I WAS IN. *TR

WE WERE TRAVELING 60 MILES TO WORK WHEN MY HUSBAND NOTICED THAT THE BRAKES WERE NOT FUNCTIONING PROPERLY. THEY BECAME VERY HARD TO PRESS DOWN AND SLOW TO STOP. WE IMMEDIATELY TOOK IT INTO A MECHANIC OFF THE FREEWAY WHO INSPECTED THE VEHICLE AND TOLD US THAT HE HAD NEVER SEEN ANYTHING LIKE IT. WE NEEDED TO TAKE IT BACK TO THE DEALER. THE POWER BOOST HAD FAILED. WE HAD IT TOWED TO THE MAZDA DEALER WHO INFORMED US THAT IT WAS ON RECALL. WE DID NOT RECEIVE A RECALL NOTICE NOR DID WE KNOW ABOUT THIS. WE ARE LUCKY TO BE ALIVE THE DISTANCE THAT WE HAD TO TRAVEL. THE DEALER ALSO TOLD US TO CALL A MAZDA TOWING NUMBER AS IT WAS ON RECALL - BUT EVEN THO THE CAR IS ONLY 2 YEARS OLD - THEY SAID IT HAD TOO MANY MILES TO BE TOWED FOR FREE. *TR

WHILE MOVING AT APPROXIMATELY 20 MPH IN A NORMAL DRIVING PROFILE ON A CLEAR DAY 73 DEGREE DAY WITH NO PRECIPITATION, I ATTEMPTED TO SLOW AND STOP THE VEHICLE PROGRESSIVELY UTILIZING THE BRAKE SYSTEM ON THE VEHICLE. I WAS UNABLE TO STOP AT MY INTENDED POINT AND DROVE PAST THE STOP SIGN; APPROXIMATELY ONE HALF CAR LENGTH FORWARD OF THE STOP SIGN AND INTO THE INTERSECTION. FOLLOWING THE EVENT, THE FEEDBACK FROM THE BRAKING SYSTEM THOROUGH THE BRAKE PEDAL FELT HARD AND THE SYSTEM WAS EXTREMELY UNRESPONSIVE. IN SUBSEQUENT STOPS THE SAME AFTERNOON, I WAS FORCED TO DOUBLE MY BRAKING DISTANCE AND CAR LENGTH TO ACCOUNT FOR THE BRAKING SYSTEMS UNRESPONSIVENESS. IN THE EVENT I WAS REQUIRED TO CONDUCT A HARD STOP AT HIGH SPEED, IT IS UNLIKELY I WOULD BE ABLE TO STOP THE VEHICLE IN THE CONDITION I EXPERIENCED 9/12/14. AFTER SPEAKING WITH ANOTHER DRIVER OF THE SAME VEHICLE, THIS EVENT (WHILE MORE SEVERE) HAS BECOME A COMMON OCCURRENCE OVER THE LAST 2 WEEKS. THAT IS; AN UNRESPONSIVE BRAKE SYSTEM ACCOMPANYING VARYING DEGREES OF BRAKING SYSTEM FAILURE RESULTING IN UNPREDICTABLE VEHICLE BEHAVIOR AND POOR STOPPING CAPABILITY. MILEAGE 19384. *TR

ON 8/29/14, MY CAR WOULD NOT STOP AND CONTINUED TO MOVE WHEN I PRESSED ON THE BRAKES TO STOP AT A TRAFFIC LIGHT, ALMOST HIT THE CAR IN FRONT OF ME. SCARY! AGAIN AT THE NEXT STOP SIGN, THE CAR CONTINUED WITHOUT STOPPING WHEN I PRESSED ON THE BRAKES. MAZDA TOLD ME THAT MY CAR IS OUT OF WARRANTY SO I WENT TO A MECHANIC WHO REPLACED A DEFECTIVE MASTER CYLINDER. A WEEK LATER, MY CAR STALLED TWICE WHEN I WAS STOPPED AT A RED LIGHT. THEN THE BRAKES "HISSED" WHEN I PRESSED ON THEM. THE BRAKE PEDAL WAS VERY HARD TO PRESS AND THE CAR WOULD CONTINUE TO COAST EVEN WHEN THE BRAKES WERE PRESSED. SCARY FOR MY CHILDREN! THE SAME MECHANIC CALLED MAZDA, AND WAS INFORMED THAT THERE IS AN EXTENDED WARRANTY ON A BRAKE BOOSTER. I DID NOT RECEIVE ANY SUCH NOTICE FROM MAZDA. MAZDA REPLACED THE BRAKE BOOSTER AND BRAKE SWITCH TODAY FOR FREE. ALSO NOTE, THE DAY I BOUGHT THIS CAR, BRAND NEW ON DEC 2, 2011, I DROVE ON THE TURNPIKE AND REALIZED THE TRANSMISSION WAS SLIPPING. I TOOK IT BACK TO MAZDA AND THEY REPLACED A DEFECTIVE TURBINE SPEED SENSOR ON MY CAR. ENOUGH! *TR

VEHICLE LOST BRAKING POWER. VEHICLE WAS BEING DRIVEN (INFANT INSIDE) FROM CHICAGO TO EVANSVILLE, IN WHEN BRAKES STARTING TO RESPOND IN A DELAYED MANNER FROM WHEN BRAKE PEDAL WAS ACTUALLY PRESSED. BY NEXT MORNING THE VEHICLE DID NOT BRAKE. MAZDA DEALERSHIP CHECKED THE VEHICLE AND MENTIONED THAT SOMEHOW MASTER CYLINDER AND BOOSTER FAILEDWITH NO APPARENT REASON AS THEY WERE ABLE TO TELL NO ABUSIVE OR INCORRECT USE WAS APPLIED TO THE VEHICLE. MAZDA WILL REPLACE PARTS THAT FAILED TO WORK BUT IT PLACED MY FAMILY IN A VERY DANGEROUS SITUATION. *TR

LIKE OTHERS, I HAVE BEGUN TO EXPERIENCE SIGNIFICANT PROBLEMS WITH THE BRAKING SYSTEM ON MY 2012 MAZDA CX-9. WHEN DEPRESSED, THE BRAKES MAKE A HISSING SOUND AND IT IS VERY DIFFICULT TO DEPRESS THE BRAKE PEDAL. ONCE DEPRESSED, THERE IS A DELAY IN BRINGING THE VEHICLE TO A STOP WHICH POSES A SIGNIFICANT SAFETY ISSUE. IT IS ALMOST AS IF POWER HAS BEEN LOST IN THE BRAKING SYSTEM. CASUALLY CONSULTED WITH THE GENTLEMAN PERFORMING STANDARD MAINTENANCE (OIL CHANGE) ON THE VEHICLE TODAY. BRAKE FLUID IS FULL. TO HIM, IT SOUNDED LIKE A BOOSTER PROBLEM WHICH, IF OTHER REPORTS HERE ARE CORRECT, SOUNDS TO BE A GOOD GUESS. A RECALL IS IN ORDER. *TR
