2012 Mazda CX-9 Complaint Log

WHILE DRIVING ON INTERSTATE 90 WEST IN MASSACHUSETTS, 5 MILES FROM ROUTE 84, OUR AWD CX-9 STARTED MAKING A VERY LOUD WHINING NOISE. WITHIN 10 SECONDS, THE CAR STARTED BUCKING, MAKING A GRINDING NOISE AND THE STEERING BECAME DIFFICULT. I WAS ABLE TO MANEUVER TO THE LEFT SIDE OF THE ROAD; I COULD NOT MAKE IT TO THE BREAKDOWN LANE BECAUSE OF THE CAR'S CONDITION. ONCE THE CAR STOPPED, WE SMELLED BURNING FLUID AND SOME SMOKE CAME OUT OF THE VENTS INSIDE THE CAR. THE CAR WAS UNABLE TO DRIVE ON ITS OWN, THE WHEELS SEEMED LOCKED AND THE GRINDING NOISE WAS EXTREMELY LOUD WHEN IN DRIVE OR NEUTRAL. I HAD TO CALL 911. THE MASS STATE HIGHWAY PATROL ARRIVED AND HAD TO PUSH US OVER TO THE BREAKDOWN LANE WHILE THE CAR WAS IN NEUTRAL. THE THE MASS STATE POLICE HALTED ALL TRAFFIC ON THE HIGHWAY FOR THIS TO OCCUR. WE SAT IN THE BREAKDOWN LANE FOR AN HOUR WAITING FOR A TOW TRUCK. THIS ENTIRE SITUATION WAS VERY DANGEROUS. I HAD A TODDLER IN THE CAR WITH US. THE HIGHWAY WAS ONLY MOVING AROUND 35-40 MILES AN HOUR AND SLOWING AT THE TIME OF THE INCIDENT. THE MASS STATE HIGHWAY PATROL AND TOW TRUCK DRIVER STATED THAT THE CAR MAY HAVE SPUN OUT OR FLIPPED IF THE HIGHWAY WAS MOVING AT SPEED DUE TO SUCH A CATASTROPHIC STEERING FAILURE. THE CX-9 HAD STARTED MAKING A OCCASIONAL QUIET WHINING SOUND IN THE DAYS PRIOR TO THE FAILURE, ON OUR DRIVE FROM VIRGINIA TO MASS . THERE WAS NO OTHER WARNING, NO WARNING LIGHTS ON THE DASH AT ALL. THE CAR WAS TOWED TO THE CLOSEST MAZDA DEALERSHIP AND WAS DIAGNOSED WITH AN INTERNAL FAILURE IN THE TRANSFER CASE. THE REPAIR WAS COVERED UNDER OUR POWER TRAIN WARRANTY, AS THE CAR ONLY HAD 28,764 MILES AT THE TIME OF THE INCIDENT AND IS 3 YEARS OLD.THE MAZDA DEALER SAID THERE HAVE BEEN NUMEROUS TRANSFER CASE FAILURES IN AWD CX-9S. I WANT TO SEE THIS PART RECALLED BECAUSE THIS FAILURE CREATED A VERY DANGEROUS SITUATION FOR MY FAMILY.

BRAKE PEDAL MAKES HISSING SOUND WHEN DEPRESSED LIKE AIR LEAKAGE; INTERMITTENTLY VERY DIFFICULT TO DEPRESS BRAKE PEDAL WITH A LOT OF FORCE APPLIED (TYPICALLY IF PUMPING BRAKE), LEADING TO INCREASED STOPPING DISTANCE/DIFFICULT STOPPING. OCCURS WHEN BRAKES DEPRESSED (SOFT PEDAL, AIR HISSING); IF DEPRESSED AGAIN IN QUICK SUCCESSION, VERY HARD TO PRESS WITH SIGNIFICANTLY REDUCED STOPPING POWER. OCCURS WHETHER VEHICLE STANDING OR IN MOTION. *JS

THE VEHICLE PRESENTS A FAILURE IN THE BRAKE PEDAL, WHICH GETS HARDER TO PRESS AND THE BRAKE POWER IS DIMINISHED, IF PRESSED HARDER THE PEDAL WILL GET SOFTER AND THE BRAKE POWER INCREASES BUT THE SENSATION OF RELIABILITY AND SAFETY WHEN BRAKING IS AFFECTED. ALSO, WHEN THE BRAKE PEDAL IS DEPRESSED HARD A HISSING SOUND IS HEARD.

CAR WOULD NOT STOP WHEN BACKING OUT OF GARAGE. THE BRAKE PEDAL WAS STIFF CAUSING THE CAR TO ROLL OFF THE DRIVEWAY AND INTO THE SIDE YARD. WE TRIED TO DRIVE THE CAR BACK INTO THE GARAGE BUT THE BRAKE PEDAL RESISTANCE WAS INCONSISTENT - FROM FIRMER THEN USUAL TO LESS FIRM - MAKING IT DIFFICULT TO STOP THE CAR. WHEN THE BRAKE PEDAL IS PRESSED, A "HISSING" SOUND IS AUDIBLE. THE MAZDA DEALERSHIP DETERMINED THE BRAKE BOOSTER WAS LOSING VACUUM. THE DEALERSHIP REPLACED THE BRAKE BOOSTER. THIS IS A KNOWN MAZDA ISSUE, BUT THEY CONTINUE TO MANUFACTURE THIS CAR WITHOUT A CORRECTION. THERE SHOULD BE A MANDATORY RECALL. THE DEALERSHIP WAS NOT ABLE TO TELL ME DEFINITIVELY IF THE NEW BRAKE BOOSTER HAS THIS FLAW CORRECTED. THIS ISSUE COULD CAUSE A FATALITY.

I OWN A 2012 MAZDA CX9 . MY WIFE WEIGHS ABOUT 105LBS AND ABOUT 115LBS WITH HER USUAL LAP DOG. INITIALLY THE PAX SEAT AIRBAG WARNING LIGHT CAME ON INTERMITTENTLY WHEN SHE WAS IN THAT SEAT, CAR IN MOTION OR NOT. THE LIGHT WAS NORMAL WHEN I SAT IN THAT SEAT. TOWNE MAZDA RAN A TEST ON THE COMPONENTS. THEY INFORMED ME THE SYSTEM CHECKED NORMAL. HOWEVER, THE LIGHT AFTER THAT THEN ILLUMINATED EVERY TIME SHE OCCUPIED THE PAX SEAT. THE PROBLEM WAS DEMONSTRATED TO A SERVICE TECH; THE LIGHT WAS OFF WITH HIM IN THE SEAT (A LARGER MAN THAN ME) AND ON EVERY TIME MY WIFE SAT IN THE SEAT. SHE ATTEMPTED TO SHIFT HER POSITION, BUT NO POSITION DELETED THE LIGHT. I WAS INFORMED THAT THE DEALER WOULD CHECK WITH MAZDA, TO SEARCH FOR A SOLUTION. AFTER MONTH OF USING THE CAR, THE LIGHT HAS BEEN ON CONTINUALLY WHEN MY WIFE OCCUPIES THE PAX SEAT. THE SERVICE SUPERVISOR TOLD ME TO PUT HER IN THE BACK SEAT BECAUSE THERE IS NO WAY TO FIX THE PROBLEM.

MY BRAKES ARE FAILING. I FIRST NOTICED THE BRAKES WERE SPONGY AND THERE WAS A HISSING SOUND IN THE CABIN. THEN THE BRAKES BECAME VERY HARD. I WAS VERY AFRAID I WAS GOING TO HIT VEHICLES IN FRONT OF ME. ALSO, EVENTUALLY THE CAR WOULD DIE WHEN THE BRAKES WERE APPLIED. THE MAZDA DEALERSHIP TOLD ME IT IS THE BRAKE POWER BOOSTER. THIS IS VERY COMMON. PLEASE, PLEASE RECALL THESE VEHICLES. I BOUGHT THIS VEHICLE USED AND IT WOULD HAVE BEEN NICE TO KNOW ABOUT THIS DANGEROUS PROBLEM.

AS I WAS DRIVING I NOTICED MY BRAKES MAKING A HISSING NOISE OF ABOUT DAY. THEN, THE BRAKE PEDAL BECAME HARD AND THEY FAILED TO WORK.

BRAKES PREMATURELY FAILED AFTER FEELING NUMB AND SQUISHY. UPON DIAGNOSTIC BY A LOCAL MECHANIC, IT WAS DETERMINED THAT THE BRAKE MASTER CYLINDER HAD A LEAK. IN ADDITION, THE ABS, TRACTION CONTROL AND EMERGENCY BRAKE LIGHTS CAME ON WHEN THE SYMPTOMS WERE PRESENT. ESTIMATED COST OF REPAIR $1250.

CAR OF 3YR 8MTH < 40K MI. BRAKE NOT EFFECTIVE, FADE VERY QUICKLY, ATTEMPT TO LIFT AND REAPPLY BRAKE MAKES THING WORSE. HARDER TO BRAKE. HEAR HISSING NOISE, SIMILAR TO COMPLAINED BY OTHERS HERE. MAZDA NEEDS TO RECALL BEFORE SOMEONE GETS KILLED.

TL* THE CONTACT OWNS A 2012 MAZDA CX-9. THE CONTACT RECEIVED NOTIFICATION OF NHTSA CAMPAIGN NUMBER: 15V451000 (SUSPENSION) HOWEVER, THE PART TO DO THE REPAIR WAS UNAVAILABLE. THE CONTACT STATED THAT THE MANUFACTURER EXCEEDED A REASONABLE AMOUNT OF TIME FOR THE RECALL REPAIR. THE MANUFACTURER WAS NOTIFIED OF THE ISSUE. THE CONTACT HAD NOT EXPERIENCED A FAILURE. VIN TOOL CONFIRMS PARTS UNAVAILABLE. UPDATED 03/10/16*LJ *TR

TL* THE CONTACT OWNS A 2012 MAZDA CX-9. THE CONTACT HEARD AN ABNORMAL NOISE COMING FROM THE VEHICLE. THE CONTACT RECEIVED NOTIFICATION OF NHTSA CAMPAIGN NUMBER: 15V451000 (SUSPENSION); HOWEVER, THE PART TO DO THE REPAIR WAS UNAVAILABLE. THE CONTACT STATED THAT THE MANUFACTURER EXCEEDED A REASONABLE AMOUNT OF TIME FOR THE RECALL REPAIR. THE MANUFACTURER WAS MADE AWARE OF THE ISSUE. THE FAILURE MILEAGE WAS APPROXIMATELY 36,000. VIN TOOL CONFIRMS PARTS NOT AVAILABLE. UPDATED 03/10/16*LJ *CN

I RECEIVED A LETTER IN SEPTEMBER 2015 REGARDING A RECALL THAT INVOLVED THE FRONT SUSPENSION AND THE DANGERS THAT COULD BE INVOLVED, BUT THERE WERE NO PARTS AVAILABLE AT THIS TIME TO FIX THE PROBLEM. I STILL HAVEN'T RECEIVED NOTIFICATION OF PARTS BEING AVAILABLE 6 MONTHS LATER. NO DAMAGE HAS BEEN DONE MY VEHICLE AS OF YET HOWEVER ANOTHER SNOWY WINTER IN ILLINOIS HAS PASSED AND THE DANGER OF "SALTWATER INTRUDING INTO THE BALL JOINT, CAUSING CORROSION, WHICH CAN RESULT IN GENERATING LOOSENESS OF THE BALL JOINT IN THE FITTING". THE RESULT OF THIS CORROSION, ACCORDING TO THE RECALL LETTER, CAN CAUSE THE BALL JOINT AND LOWER ARM TO SEPARATE CAUSING LOSS OF STEERING CONTROL AND INCREASED CRASH RISK. I THINK 6 MONTHS IS AMPLE TIME TO PRODUCE PARTS NEEDED TO FIX THESE VEHICLES AND TO SAVE LIVES AND IT IS INCREDIBLY IRRESPONSIBLE OF MAZDA TO NOT EXPEDITE THIS FIX.

WE EXPERIENCED WHAT SIMILAR MAZDA CX9 OWNERS HAVE REPORTED: OUR BRAKES STIFFENED, PROVIDED RESISTANCE COUPLED WITH A HISSING NOISE, AND FAILED TO STOP THE VEHICLE IN A TIMELY MANNER, DESPITE HAVING A FULL BRAKE FLUID RESERVOIR AND SUFFICIENT BRAKE PADS. OUR MECHANIC REPORTS FAILURE OF THE MASTER CYLINDER AND THE BLOWER. WE EXPERIENCED THESE EVENTS SUDDENLY AND WHILE THE CAR WAS IN MOTION.

BRAKE PEDAL GOT HARD VEHICLE WOULD NOT STOP NO WARNING LIGHTS ALMOST REAR ENDE VEHICLE BRAKE FAILURE

WHEN APPLYING BRAKES, BRAKES DO NOT STOP COMPLETELY. THERE IS A HISSING SOUND WHEN APPLYING BRAKES. BRAKES FEEL HARDER TO PRESS THAN USUAL.

BRAKES MAKING HISSING SOUND AND THE CAR SUDDENLY STALLED WHILE WAITING ON A LIGHT. AFTER SOMETIME CAR STARTED BUT BRAKES WERE HARD AND HAD TO PRESS REALLY HARD FOR CAR TO STOP.

MAZDA RECALL 8515G ( NHTSA CAMPAIGN NO 15V451) I CALLED MAZDA MOTOR CORPORATION IN JANUARY 2016 REGARDING THE ABOVE RECALL. I WAS TOLD THAT IF I WAS HAVING A PROBLEM WITH THE RECALL PARTS IN QUESTION TO TAKE THE VEHICLE TO THE NEAREST DEALERSHIP FOR INSPECTION AND POSSIBLE REPAIR. I INQUIRE AS TO WHY MY VEHICLE WAS NOT CALLED IN FOR THE RECALL REPAIR AND TO MY AMAZEMENT I WAS TOLD THAT THEY DID NOT HAVE ENOUGH PARTS TO FIX THIS PROBLEM AND AS SOON AS THEY BECOME AVAILABLE THEY WOULD BE NOTIFYING CUSTOMERS TO BRING THEIR VEHICLES IN FOR REPAIR. RECALL, IT HAS BEEN 7 TO 8 MONTHS SINCE THE NHTSA PUT THIS RECALL OUT AND I HAVE NOT RECEIVED ANY CORRESPONDENCE FROM MAZDA REGARDING THE REPAIR OF MY VEHICLE. THE LAST CORRESPONDENCE WAS A NOTIFICATION LETTER DATED SEPTEMBER 2015 REGARDING THE RECALL. I FEEL THIS IS NOTHING MORE THAN POSTURING ON MAZDA'S PART. HOW LONG DO YOU HAVE TO WAIT BEFORE SOMEONE GETS KILLED !! PLEASE LOOK INTO THIS MATTER SOMEONE'S LIFE COULD BE AT STAKE HERE. THANK YOU FOR YOUR POSSIBLE ACTION IN THIS MATTER.

MY BRAKE FEELS LIKE IT HAS AIR UNDER IT AND IS HARD TO PRESS DOWN ON. IT ALSO MAKES A HISSING SOUND. WHEN STOPPED AT A TRAFFIC LIGHT, WITH MY FOOT ON THE BRAKE, IT FEELS LIKE MY CAR IS TRYING TO MOVE. I AM SCARED MY BRAKE WILL FAIL OR NOT WORK WHEN I PUSH ON IT. I NOTICED THIS ABOUT A WEEK AND A HALF AGO. I THOUGHT IT WAS NOTHING AT FIRST BUT IT IS STILL DOING THIS AND MORE FREQUENTLY. I AM CONCERNED THAT THIS WILL CAUSE AN ACCIDENT. I AM WORRIED SOMETHING WILL HAPPEN TO MY CHILDREN OR ME IF MY BRAKES FAIL BECAUSE OF THIS.

IN JUNE, I NOTICED THAT WHEN I STEPPED ON THE BRAKE PEDAL, IT WOULD MAKE A HISSING SOUND, LIKE AIR BEING RELEASED FROM A TIRE. RECENTLY, THE BRAKE PEDAL FEELS SOFT AND I HAVE TO STEP ON IT ALL THE WAY FOR THE CAR TO SLOWLY SLOWDOWN. BEEN IN VERY CLOSE SITUATIONS RECENTLY. I CHECKED THE BRAKE FLUID AND IT WAS LOW, SO I REFILLED IT AND TOOK IT OUT FOR A DRIVE... THIS DID VERY LITTLE. THE BRAKE PEDAL STILL MAKES A HISSING SOUND AND FEELS VERY SPONGY. IT IS NOW MAKING A BRAND NEW SOUND TOO. WHEN I STEP ON THE BRAKE PEDAL ALL THE WAY, IT MAKES A WHISTLING SOUND. VERY HIGH PITCH WHISTLING SOUND LIKE A LOT OF AIR IS TRYING TO SQUEEZE OUT OF A TINY HOLE. IF THIS IS A COMMON PROBLEM, THEY NEED TO GET THIS CAR RECALLED BECAUSE I USE IT TO TRANSPORT MY LITTLE ONES AROUND.

I WAS DRIVING HOME FROM WORK TODAY. WHEN I APPROACHED A TRAFFIC LIGHT, I DEPRESSED THE BRAKE PEDAL AND HAD TO PRESS IT VERY HARD FOR THE CAR TO STOP. GOOD THING THERE WAS NOBODY IN FRONT OF ME BECAUSE I WOULD HAVE HIT THEM. AS I STARTED TO GO AGAIN AND PROCEED TO ANOTHER LIGHT, AS I PUSHED THE BRAKE PEDAL, I HEARD A 'HISSING' SOUND COMING FROM THE PEDAL. IT ALMOST SOUNDED LIKE AIR COMING OUT OF A TIRE. THIS WAS ALARMING TO ME BECAUSE I FELT AS IF MY BRAKES WERE GIVING OUT. I HAD TO PRESS VERY HARD ON THE BRAKE AND AS IT BRAKED, IT WAS SO SUDDEN IT SHOVED ME FORWARD IN THE SEAT. I TOOK IT RIGHT OVER TO OUR SERVICE SHOP IN TOWN, AND AFTER HE TOOK THE CAR FOR A TEST DRIVE, HE DROVE IT RIGHT BACK AND PROCEEDED TO TELL ME THAT IT SOUNDS LIKE THE BRAKE BOOSTER WAS GOING. HE ADVISED ME NOT TO DRIVE THE CAR AND TO CALL AAA AND HAVE IT TOWED TO THE DEALER. I MANAGED TO GET IT BACK HOME, VERY SLOWLY, AND INTO THE GARAGE. THIS IS VERY FRIGHTENING TO ME BECAUSE MY DAUGHTER ALSO DRIVES THIS CAR ON OCCASION AND WHAT IF THE BRAKES FAILED WHILE SHE WAS DRIVING?! IN READING ALL THE POSTS WITH CUSTOMERS HAVING THIS SAME ISSUE WITH THE BRAKES, I THINK MAZDA NEEDS TO RECALL THIS PART BEFORE THEY HAVE A BIGGER LAWSUIT ON THEIR HANDS! I WILL BE CALLING THE DEALERSHIP FIRST THING TOMORROW MORNING.

TL* THE CONTACT OWNS A 2012 MAZDA CX-9. THE CONTACT RECEIVED NOTIFICATION OF NHTSA CAMPAIGN NUMBER: 15V451000 (SUSPENSION); HOWEVER, THE PART TO DO THE REPAIR WAS UNAVAILABLE. THE CONTACT STATED THAT THE MANUFACTURER EXCEEDED A REASONABLE AMOUNT OF TIME FOR THE RECALL REPAIR. THE MANUFACTURER WAS MADE AWARE OF THE ISSUE. THE VIN WAS UNKNOWN. THE CONTACT HAD NOT EXPERIENCED A FAILURE.

UPON STARTING CAR AND PUTTING CAR INTO DRIVE, BRAKES WOULD NOT STOP THE CAR INITIALLY AND HAD TO PUMP THE BRAKES SEVERAL TIMES TO EVENTUALLY KEEP THE CAR FROM ROLLING. WHEN THE BRAKES ARE PRESSED TO THE FLOOR, THERE IS A HIGH PITCHED SQUEALING SOUND AS IF THERE IS A VACUUM LEAK OR SOMETHING. I SUSPECT THAT BASED ON THE OTHER COMPLAINTS AND ARTICLES I HAVE READ THAT THE BRAKE BOOSTER HAS A COMPROMISED SEAL. THIS NEEDS TO BE A RECALL ITEM AND VERY SOON AS MANY PEOPLES' LIVES ARE BEING PUT IN DANGER BECAUSE OF THIS COMMON DEFECT IN THE CX9 FAMILY OF BRAKING SYSTEMS.

JUST AFTER SHIFTING INTO DRIVE FROM PARK, NOTICED HIGH PITCHED SQUEAL AND HISSING. BRAKES HAD TO BE PRESSED ALL THE WAY TO FLOOR IN ORDER TO STOP THE VEHICLE AT ONLY 5-10 MPH. THEN WHILE DRIVING SOMETIMES BRAKES SEEMED TO WORK FINE AND OTHER TIMES NEEDED TO DEPRESS BRAKE PEDAL ALL THE WAY TO FLOOR. SEEMS TO BE AN ISSUE THAT SHOULD BE RECALLED GIVEN SO MANY PEOPLE HAVING SUCH AN ISSUE AT LOW MILEAGE.

TL* THE CONTACT OWNS A 2012 MAZDA CX-9. AFTER ATTEMPTING TO ENGAGE THE BRAKES, THE BRAKE PEDAL FAILED TO DEPRESS. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER FOR FURTHER INSPECTION. THE VIN WAS NOT AVAILABLE. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 41,000.

I REVERSED MY VEHICLE INTO A PARKING SPOT AND STARTED HEARING ABNORMAL NOISE LIKE BRAKES GRINDING, BUT WAS STILL PRESENT EVEN WHEN NOT MOVING. HAVING A CAR BACKROUND I KNEW IT WAS MORE LIKE AIR. WASN'T SURE WHAT IT WAS, BUT BECAUSE I ALREADY WORK AT A DEALERSHIP I DECIDED TO HAVE ONE OF MY DIAGNOSTIC TECHS CHECK IT OUT. HE KNEW RIGHT FROM MY DESCRIPTION THAT IT WAS PROBABLY BRAKE BOOSTER RELATED. CALLED MY DEALERSHIP THAT ALWAYS SERVICES MY CAR FOR AN EMERGENCY DROP OFF. BRINGING THE VEHICLE TO THE DEALERSHIP, EVERY TIME I BRAKED THE PEDAL WOULD NOT GO DOWN ALL THE WAY, GO STRAIGHT TO THE FLOOR, OR I'D HAVE TO DOUBLE TAP THE BRAKES SIMILIAR TO IF I WAS DRIVING ON ICE. WHEN AT STOPS I'D HEAR THE AIR NOISE FROM THE BOOSTER, AND EVEN WHEN THE VEHICLE WAS OFF THE PEDAL GOES TO THE FLOOR. SOMETIMES I'D BE COMING TO A STOP AND THE BRAKES WOULD GRAB SUDDENLY AND I'D SLIDE FORWARD ON THE SEAT & MOST LIKELY INTO THE STEERING WHEEL IF I DIDN'T HAVE MY SEATBELT ON. THE PROBLEMS WITH THE BRAKE HAPPENED AT SUDDEN STOPS, SLOW STOPS, AND THE NOISE OF AIR WAS PRESENT AT ALL BRAKING. CHECK ONLINE FOR TSB BRAKES FOR MY VEHICLE AND SEE IT IS BECOMING A COMMON THING. VEHICLE IS AT THE DEALERSHIP CURRENTLY & IS OUT OF WARRANTY, BUT WITH THIS BEING SUCH A WELL NOTED CONCERN & OTHER ISSUES I'VE HAD I DON'T KNOW WHAT I WILL DO.

THE TRANSFER CASE IS LEAKING AND GOING TO GO COMPLETELY OUT ON MY 2012 MAZDA CX-9, I NOTICED THE SAME GEAR SHIFTING PROBLEM IN MY 2004 MAZDA 6 WAGON. THE CAR FEELS LIKE DRIVING A STICK, IT JOLTS WHEN SHIFTING TO DRIVE AND WHILE MOVING IT FEELS LIKE IT IS SHIFTING EARLY. THIS IS A KNOWN PROBLEM WITH MAZDA BUT A RECALL IS YET TO SURFACE FOR THIS ISSUE.

I EXPERIENCED UNEXPLAINED SUDDEN ACCELERATION WHILE STOPPED AT A STOP LIGHT. AT THE TIME OF THE INCIDENT THERE WAS ONE CAR STOPPED IN FRONT OF ME AND ONE BEHIND ME. FROM THE ONSET OF THE INCIDENT IT TOOK JUST A VERY FEW SECONDS, PROBABLY BETWEEN TWO AND FOUR, FOR THE ENGINE TO REV TO AN EXTREMELY HIGH SPEED. WHILE THIS WAS HAPPENINGS I COULD FEEL THE VEHICLE ATTEMPTING TO MOVE FORWARD FORCEFULLY WHILE I WAS APPLYING THE BRAKES VERY HARD. I SHIFTED INTO NEUTRAL AND TURNED OFF THE IGNITION. I THEN SHIFTED INTO PARK. I TURNED THE IGNITION ON AGAIN AND THE ENGINE CONTINUED TO REV AT A VERY HIGH SPEED. I IMMEDIATELY SHUT OFF THE ENGINE. I DECIDED TO START THE VEHICLE ONE MORE TIME. THIS TIME WHEN I TURNED ON THE IGNITION THE VEHICLE RAN NORMALLY. I CAUTIOUSLY DROVE IT FOR POSSIBLY FIVE MILES AND PARKED IT WHERE I COULD HAVE IT TOWED TO THE DEALERSHIP. I WAS ASKED ABOUT FLOOR MATS.THE ORIGINAL FLOOR MATS WERE IN THE VERY BACK OF THE VEHICLE AND I HAD WEATHERTECH MATS, IN THE FRONT OF THE CAR, WHICH WERE ATTACHED TO HOOKS IN THE FLOOR HOLDING THEN IN PLACE. THE DEALERSHIP DID TAKE THE SITUATION VERY SERIOUSLY. THEY DID INDICATED CONCERN ABOUT HAVING THE VEHICLE ON THE ROAD AGAIN. THEY TESTED THE VEHICLE FOR ANY COMPUTER CODES WHICH MIGHT INDICATE WHAT MAY HAVE CAUSED THE PROBLEM AND FOUND NOTHING. THEY CONTACTED MAZDA AND AT THE TIME THAT I SOLD THE CAR BACK TO THE DEALERSHIP THEY HAD NOT HEARD ANYTHING FROM MAZDA.

BRAKE PEDAL BECAME DIFFICULT TO DEPRESS AND VEHICLE ALSO DIFFICULT TO STOP. DIDN'T TAKE BUT A QUICK SEARCH TO FIND MANY OTHER OWNERS OF THESE VEHICLES EXPERIENCING THE SAME THING BASED ON THEIR DESCRIPTIONS. IT'S SO COMMON IT SHOULD ALREADY BE A RECALL. MAZDA SHOULD LEARN FROM OTHER MANUFACTURERS MISTAKES AND BE PROACTIVE AND NOT REACTIVE. WE ALREADY REGRETTED PURCHASING THE VEHICLE AND THIS SOLIDIFIES ARE DECISION TO TRADE IT IN AND NEVER PURCHASE A MAZDA AGAIN. *TR

PULLED OUT OF MY DRIVEWAY THIS MORNING AND TRIED TO USE MY BRAKES -- HEARD A HISSING, SQUEAKING SOUND AND THE CAR DIDN'T STOP. I PUMPED THE BRAKES SEVERAL TIMES WAS ABLE TO SLOW THE VEHICLE DOWN. BRAKES FELT EXTREMELY SLUGGISH FOR THE REST OF MY MORNING DRIVE (DROPPING OFF MY DAUGHTER AT HER SCHOOL). AT A STOPLIGHT THE CAR STALLED, WHICH HAS NEVER HAPPENED BEFORE. TOOK IT TO MY MECHANIC WHO SAID THE COMPUTER WAS KICKING OUT MULTIPLE CODES WHICH SEEMED TO BE RELATED TO THE BRAKE BOOSTER SYSTEM. HE RECOMMEND I TAKE THE VEHICLE TO A LOCAL MAZDA DEALERSHIP B/C IT MIGHT STILL BE UNDER WARRANTY. THE MAZDA DEALER JUST CONFIRMED THAT THE PROBLEM IS RELATED TO THE SUPPOSEDLY KNOWN FAULTY BRAKE BOOSTER SYSTEM AND A LEAK IN THE VACUUM. MAZDA WILL REPLACE THE PARTS FOR FREE AND NOT CHARGE ANY LABOR, EITHER. VERY SCARY ISSUE -- I NEARLY HIT SEVERAL VEHICLES ON MY DRIVE THIS MORNING AND WAS LUCKY THAT THE CARS IN FRONT OF MY MOVED TO AVOID AN ACCIDENT. MAZDA NEEDS TO RECALL ALL CARS WITH THIS ISSUE BEFORE SOMEONE IS INJURED, OR WORSE. *TR

AT VARYING SPEEDS, THE BRAKES ARE VERY DIFFICULT TO APPLY. WHEN APPLIED FULLY, A LOUD SQUEALING CAN BE HEARD FROM THE DASHBOARD AREA. THE VEHICLE IS CURRENTLY AT A SERVICE CENTER FOR EVALUATION. *TR

VACUUM LEAK ON BRAKE BOOSTER. CAN HEAR THE LEAK WHEN DEPRESSING PEDAL. BECOMES VERY HARD WHEN DEPRESSED FULLY AND IS HARD TO STOP, THIS IS A WELL DOCUMENTED PROBLEM. *TR

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

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

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

ON JANUARY 7,2015 I WAS DRIVING ON THE LONG ISLAND EXPRESS WAY MERGING OFF THE RAMP BACK ONTO THE HIGH WAY WHEN I COULDN'T BREAK. MY BREAKS DIDN'T WORK. I KEPT ON PRESSING THEM DOWN AND NOTHING WAS WORKING. TRUCKS WERE ALL HONKING AT ME BECAUSE I WAS MERGING WITHOUT STOPPING. FINALLY I WENT OFF THE RAMP ONTO THE GRASS. I CALLED THE DEALERSHIP AND WAS INFORMED THAT THERE IS A RECALL REGARDING THIS PROBLEM. NEVER GOT ANYTHING IN THE MAIL FROM THEM STATING OF SUCH THING.I TOOK THE CAR IN AND I DON'T OWN THE CAR ANYMORE BECAUSE I WAS BEYOND AFRAID AFTER THIS SITUATION.

WHEN PUMPING GAS IN THE FUEL TANK, THE GAS SPEWS OUT WHEN THE PUMP STOPS. THIS CAUSES THE GAS TO SPILL DOWN THE SIDE OF THE CAR.

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

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

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

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

WHILES DRIVING AND APPROACHING A STOP LIGHT OR TRAFFIC LIGHT, THE BRAKES DEPRESS AND THE CAR DOESN'T STOP, THE BRAKES HAVE TO BE PUMPED BUT THEN THEN THE BRAKES ARE HARD/STIFF SO MUCH SO THAT YOU HAVE TO PUSH REALLY HARD FOR THE CAR TO STOP. ONCE THIS HAPPENS, IT RECURS ALL THE TIME. THE ENGINE CHECK LIGHT CAME ON A DAY LATER, NOT SURE IF IT RELATED, I ASSUME SO FOR NOW. MY CAR HAS LESS THAN 10,000 MILES ON IT. I NOTICE THERE IS RECALL NOTICE FOR THIS CONDITION BY MAZDA BUT THIS IS AN EXTREMELY DANGEROUS SITUATION, WHICH SHOULD BE FIXED AT ONCE. IT SEEMS TO BE A LEAST EFFORT TYPE OF RECALL NOTICE FOR AN EXTREMELY DANGEROUS SITUATION. TO SUMMARIZE, WHILES DRIVING YOUR BRAKES FAIL AND THE CAR DOES NOT STOP. WHEN YOU PUMP THE BRAKES, THEY ARE STIFF / HARD AND YOU HAVE TO PUSH DOWN REALLY HARD FOR THE CAR TO STOP. *JS

FOLLOWING UP A PREVIOUS COMPLAINT THAT BRAKES ARE HARD AND REQUIRE LONGER STOPPING DISTANCE. I TOOK THE CARD TO THE DEALER FOR A HISSING SOUND THE BRAKES WERE MAKING AND THEY SAID IT WAS FINE. I AM TAKING MY CAR BACK TO THE DEALER BECAUSE THE PROBLEM HAS GOTTEN SIGNIFICANTLY WORSE OVER THE LAST MONTH. I DO NOT FEEL SAFE DRIVING MY CAR AND I HAVE LESS CONFIDENCE IN THE BRAKE SYSTEM. *TR

BRAKES LOST PRESSURE, REQUIRING SIGNIFICANT INCREASE IN FORCE APPLIED TO THE BRAKES TO BRING VEHICLE TO A STOP. WHEN BRAKE PEDDLE WOULD BE DEPRESSED, IT WOULD MAKE A HISSING TYPE OF NOISE. *TR

I'VE PURCHASED 2012 MAZDA CX-9 AWD IT LATE NOVEMBER OF 2011.RECENTLY I'VE BEEN EXPERIENCING MULTIPLE UNEXPECTED LOSS OF POWER-ASSISTED BRAKES FAILURE INCIDENT .I WAS IN A MINOR FENDER BENDEER. THANK GOD THE DRIVER INFRONT WAS VERY NICE AND DIDNT FILE ANY CLAIM AGAINST MY INSURANCE. WHEN I BROUGHT MY VEHICLE INTO MAZDA SERVICES DEPARTMENT TO GET IT RESOLVE. INSTEAD OF TAKING UNEXPECTED LOSS OF POWER-ASSISTED BRAKES AS AN URGENT MATTER. THEY TOLD ME THAT MY CAR IS DRIVABLE AND IT STILL BREAK. I CAN DRIVE MY MAZDA IN THE MEANWHILE, UNTIL THEY HAVE AN OPEN APPOINTMENT FOR MY MAZDA TO BE SEEN. AFTER SPEAKING TO MULTIPLE PERSONEL AT THE SERVICES DEPARTMENT.
