2010 Mazda CX-9 complaints

I WAS DRIVING AROUND A SHARP BEND IN THE ROAD. I PUSHED DOWN ON THE BRAKE PEDDLE TO SLOW DOWN AND THE CAR KEPT ACCELERATING AT THE SAME SPEED. THE CAR NEVER SLOWED DOWN AND I HAD TO TAKE THE CORNER AT A UNSAFE SPEED. I DROVE TO THE NEXT STREET AND TESTED THE BRAKES AND THEY WORKED FINE? VERY SCARY INCIDENT. *TR

TL* THE CONTACT OWNS ON A 2010 MAZDA CX9. THE CONTACT STATED THAT THE BRAKE PEDAL BECAME STUCK TO THE FLOORBOARD AND MADE A STRANGE NOISE WHILE ATTEMPTING TO STOP. THE CONTACT WAS ABLE TO RELEASE THE BRAKE PEDAL AND BROUGHT THE VEHICLE TO A STOP BY DEPRESSING THE BRAKE PEDAL SEVERAL TIMES. THE CONTACT WAS ABLE TO DRIVE THE VEHICLE TO AN INDEPENDENT MECHANIC FOR FURTHER INSPECTION. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE AND CURRENT MILEAGE WAS 51,000.

I NOTICED A HISSING SOUND WHEN PRESSING THE BRAKE PEDAL TODAY 3/20/2014 AND LOSS OF BRAKE PRESSURE. I NOTIFIED THE DEALER AND THEY PROMPTLY TOLD ME TO BRING IT IN RIGHT AWAY TO BE LOOKED AT. I DID HOWEVER A GOOGLE SEARCH FOR MAZDA CX9 BRAKE ISSUE AND NOTICE THERE ARE 7 OTHER INCIDENTS WITH CX-9 BRAKE ISSUE EXPLAINING THE SAME SYMPTOMS. "THE NHTSA COMPLAINTS SAY THAT THE PROBLEM CAUSES A HARD PEDAL, INCREASED BRAKING EFFORT AND REDUCED BRAKING EFFECTIVENESS. SOME COMPLAINTS ALLEGE THAT THEY HEAR A HISSING NOISE DURING BRAKING SIMILAR TO THE SOUND OF AIR LEAVING THE TIRES. NO INJURIES OR CRASHES HAVE BEEN REPORTED." I SHOWED THE DEALERSHIP THE GOOGLE SEARCH FROM THE INTERNET...PERTAINING TO 2010 CX-9 BRAKE ISSUES. MAZDA DEALER SOUNDS LIKE THEY ARE AWARE OF THE PROBLEM...AND SHOULD BE TAKING PROACTIVE CORRECTIVE MEASURES TO FIX THIS PROBLEM. *TR

THE CAR HAS BEEN TURNING OFF WHILE DRIVING WITH NO PRIOR INDICATIONS OR WARNINGS. ENGINE TURNS OFF AND STEERING WHEEL FREEZES AND LOCKS UP. THIS HAS OCCURRED MULTIPLE TIME AND WE HAVE TAKEN THE CAR TO THE DEALER A NUMBER OF TIMES WHO HAS INSPECTED IT AND EVEN KEPT IT AT THE SHOP DROVE IT FOR A NUMBER OF DAYS AND COULD NOT PINPOINT THE PROBLEM. WE HAVE MADE MAZDA USA AWARE OF THE ISSUE AND THE POTENTIAL THREAT OF THIS VEHICLE (THEY GAVE US A CASE # 149456450) HOWEVER, SADLY THEIR ATTITUDE IS THAT IF THE PROBLEM CANT BE PINNED THEN IT DOES NOT EXIST. THIS IS A CLEAR IGNORANCE ON MAZDA USA'S PART AND PUTTING THE PUBLIC IN A RISK WITH THIS VEHICLE. *TR

SEVERAL WEEKS AGO THE BRAKES STARTED MAKING A HISSING NOISE WHEN I WOULD DEPRESS THE BRAKE. THEN, THE CAR WOULD BRAKE AS USUAL UNTIL I NEEDED TO COME TO A COMPLETE STOP, WHEREAS THEN I WOULD NEED TO DEPRESS THE BRAKE VERY HARD TO MAKE THE CAR STOP, WHICH THEN IT WOULD STOP VERY SUDDENLY. THE MOST RECENT EVENT OCCURRED WHEN MY HUSBAND WAS DRIVING DOWN THE ROAD ABOUT 45 MPH AND HAD HIT THE BRAKES AND THE ENGINE COMPLETELY SHUT OFF, ALL THE WARNING LIGHTS CAME ON AND IT WAS VERY DIFFICULT FOR MY HUSBAND TO PULL THE CAR OVER AND COME TO A STOP. THE ENGINE DID START BACK UP AND WE DROVE ALL THE WAY HOME AND HAVE NOT SINCE DRIVEN THE VEHICLE. *TR

VEHICLE MAKES A HISSING SOUND (HEARD INSIDE THE VEHICLE) WHEN DEPRESSING THE BRAKE PEDAL. SOUNDS LIKE AN AIR LEAK. OCCASIONALLY THE PEDAL WILL GO HARD AS IF POWER ASSISTED BRAKING FEATURE IS LOST. VERY DANGEROUS SITUATION! VEHICLE TAKEN TO DEALER TODAY (02/24/14) AND WAS TOLD REPLACEMENT BRAKE BOOSTER IS REQUIRED. *TR

VEHICLE WAS PARKED IN A GARAGE (NOT HEATED) AFTER TRAVELING APPROXIMATELY 18 MILES FROM WORK WITH TEMPERATURES IN THE TEENS. AFTER BEING PARKED IN THE GARAGE UNATTENDED FOR APPROXIMATELY 10 MINUTES, THE SUNROOF EXPLODED. THE SOUND COULD BE HEARD FROM INSIDE THE HOUSE. WHEN I INVESTIGATED, THE REMAINING GLASS THAT WAS STILL IN TACT WAS POINTED TOWARDS THE CEILING OF THE GARAGE. WHILE TAKING PICTURES, THE GLASS CONTINUED TO CRACK, POP, AND EXPLODE INTO THE AIR AND ONTO THE HOOD OF THE CAR. *TR

DRIVING IN SNOWY CONDITIONS; BRAKES FAILED TWICE WHEN I APPLIED LIGHT PRESSURE. FIRST TIME, THE BRAKES SHUDDERED, BUT THE CAR FINALLY STOPPED AFTER I APPLIED HARD PRESSURE; THE SECOND TIME IT HAPPENED, THE BRAKES SHUDDERED, AND NOTHING HAPPENED WHEN I FIRST APPLIED HARDER PRESSURE. EVENTUALLY THE CAR SKIDDED, BUT IT WAS TOO LATE. *TR

DRIVING, HAD MY 2 YEAR OLD SON AND 7 YEAR OLD DAUGHTER IN THE CAR, A CAR SLOWED IN FRONT OF ME AND WHEN I PUSHED THE BRAKES THEY FELT HARD AS A ROCK AND THE CAR WOULD NOT STOP. SLOWED DOWN AT A VERY SLOW PACE WHILE PUSHING ON THE BRAKES AS HARD AS I COULD. I PRACTICALLY HAD TO STAND UP. I WAS HORRIFIED. MY BRAKES CONTINUE TO DO THIS. SOMETIMES THEY FEEL VERY HARD AND SOMETIMES THEY PUSH DOWN BUT SOUND AS IF AIR IS LEAKING OUT. I AM TAKING THE CAR IN TOMORROW TO SEE WHAT IS GOING ON. OBVIOUSLY SOMETHING IS WRONG, BUT THERE ARE NO WARNING LIGHTS ON OR ANYTHING. I LOOKED FOR RECALLS ON THE BRAKES AND HAVE FOUND NOTHING. I HAVE FOUND OTHERS HAVE HAD THE SAME ISSUE AND HOPE THAT THERE IS A RECALL BEFORE SOMEONE GETS HURT OR EVEN KILLED. THIS WAS A VERY SCARY EXPERIENCE.....MY CHILDREN AND I WERE FORTUNATE I WAS ABLE TO GO INTO THE OTHER LANE WITHOUT CRASHING. *TR

WHILE DRIVING MY 2010 MAZDA CX-9 APPROXIMATELY 65MPH ON INTERSTATE 270S IN MARYLAND, I PRESSED THE GAS PEDAL TO ACCELERATE IN AN ATTEMPT TO PASS SEVERAL VEHICLES WHO WERE TRAVELING IN THE RIGHT HAND LANE. ONCE I FELT THAT I HAD ENOUGH ADDITIONAL SPEED TO SUCCESSFULLY PASS THE VEHICLES, I RELEASED THE GAS PEDAL AND NOTED THAT THE CAR CONTINUED TO ACCELERATE. I ATTEMPTED TO APPLY MY BRAKES, BUT THEY WOULD NOT SLOW THE VEHICLE. AFTER SEVERAL UNSUCCESSFUL ATTEMPTS TO APPLY MY BRAKES, I SEARCHED FOR A SAFE PLACE TO CONTINUE TRAVELING AS MY VEHICLE CONTINUED TO ACCELERATE, NOTING I WOULD NEED TO SHIFT INTO NEUTRAL AND MOVE INTO THE MEDIAN. LUCKILY, AFTER NUMEROUS REPEATED ATTEMPTS, MY BRAKES FINALLY ENGAGED AND SLOWED THE VEHICLE. I FEEL THIS IS A MANUFACTURER'S DEFECT THAT COULD ULTIMATELY LEAD TO A FATALITY. I AM TOO SCARED TO DRIVE THE VEHICLE AT THIS POINT IN TIME. *TR

BRAKES WOULD NOT WORK AS USUAL. AFTER "STOMPING" ON BRAKE, CAR CONTINUED TO MOVE FOR SEVERAL FEET. THERE WERE NO WARNING LIGHTS OF BRAKE FAILURE WHATSOEVER. TOOK VEHICLE TO DEALER TO BE INFORMED THE MASTER CYLINDER AND BRAKE POWER BOOSTER WERE OUT AND THE CAR WAS DANGEROUS TO DRIVE. VERY GLAD NOBODY GOT HURT. COUPLE ISSUES: THIS BRAKE FAILURE IS FAIRLY WIDESPREAD WITH THIS MAKE/MODEL/YEAR AS I'VE FOUND FROM RESEARCH. WHY IS THERE NO RECALL? THERE'S NOT EVEN A TECHNICAL ADVISORY FROM MAZDA ABOUT THIS SERIOUS THREAT TO DRIVERS OF THIS CAR. DOES SOMEBODY HAVE TO GET HURT FIRST? SECOND, I GET THAT PARTS GO BAD - BUT ON SOMETHING AS IMPORTANT AS THE BRAKE SYSTEM, THE CAR SHOULD SOUND SOME SORT OF ALARM, LIGHT A DUMMY LIGHT....SOMETHING TO TELL THE DRIVER TO STOP DRIVING THE CAR AS THEY ARE IN IMMINENT DANGER. TO NOT ADDRESS AT LEAST THIS SECOND ISSUES IS NEGLECTFUL OF MAZDA AND THE NTSB. TO NOT ADDRESS THE MECHANICAL FAILURES BY WAY OF RECALL IS ALSO EXTREMELY NEGLIGENT. *TR

THIS INDIVIDUAL BROUGHT THE CAR IN TO THE DEALER COMPLAINING OF HIGH PITCHED SQUEAKING SOUND FROM BRAKES. DEALERSHIP CHECKED BRAKES AND SAID NOTHING WRONG. PICKED UP CAR NEXT DAY AND FELT THAT CAR NOT RIDING WELL AND LET IT SIT IN DRIVEWAY FOR 2 DAYS. WENT TO DRIVE AGAIN AND PEDAL WAS "HARD" AS IF IT WAS ON THE FLOOR. THEN WHENEVER I PRESSED ON THE PEDAL, I HEARD A HISSING SOUND AS IF AIR WAS LETTING OUT OF TIRES. CAR RESPONSE FOR SLOWING TO A STOP MUCH LONGER. CALLED DEALER ASAP AND ARRANGED TO DROP CAR OFF THAT NIGHT. DEALER CALLED NEXT DAY TO SAY GOOD THING WE DROPPED CAR OFF NIGHT BEFORE AS THERE WAS LITTLE TO NO BRAKES LEFT DUE TO POWER BOOSTER FAILURE. HOW WAS IT THAT I COULD TELL BRAKES WERE GOING BUT DEALER COULD NOT? THIS IS A LEASED CAR. 10 WEEKS LEFT ON LEASE. PAST WARRANTY. $800 REPAIR. CLEARLY MAZDA IS HAVING AN ISSUE WITH THE 2010 CX-9 POWER BOOSTER DUE TO THE NUMBER OF COMPLAINTS LODGED ON THIS SITE. THE SERVICE DEPARTMENT FOR THE DEALER WORKED VERY HARD ON MY BEHALF AND WAS ABLE TO GET MAZDA TO COVER MOST OF THE REPAIR, THE DEALER PICKED UP ANOTHER $200 AND I HAD TO PAY $100. FAIR I GUESS BUT SINCE THIS IS A SERIOUS ISSUE MAZDA SHOULD RECALL THE CARS AND DO THE FIX FOR FREE. *TR

WHEN I GOT IN THE CAR, THE CHECK TIRE PRESSURE LIGHT WAS ON. STOPPED AT A SERVICE STATION AND HAD THE TIRES CHECKED: ALL WAS FINE. A FEW MILES LATER, THE CAR SUDDENLY MADE A LOUD WHINING NOISE AND THEN LOUD BANGING NOISES AND THE CAR FELT LIKE IT WAS SEIZING AND SHUDDERING. PULLED TO THE SIDE OF THE ROAD, COULDN'T SEE ANYTHING AMISS UNDER THE HOOD. RE-STARTED THE CAR AND HEADED HOME WITH THE LOUD WHINING NOISE UPON ANY ACCELERATION. I CALLED THE DEALERSHIP THE NEXT DAY AND HAD IT TOWED TO THEM AS I FELT IT WAS UNSAFE TO DRIVE AFTER DOING SOME RESEARCH AND NOTING THE SYMPTOMS WERE SIMILAR TO WHAT OTHER VEHICLE OWNERS HAD REPORTED AS A TRANSFER CASE FAILURE. UPON EXAMINATION THE DEALERSHIP DID SAY IT WAS A TRANSFER CASE FAILURE AND REPLACED IT THAT DAY. I PICKED UP MY CAR TODAY AND SO FAR IT IS DRIVING AND HANDLING FINE. SEVERAL MONTHS PRIOR TO THE VEHICLE FAILURE I HAD NOTED A VERY, VERY FAINT WHINING NOISE WHEN MY SPEED WAS BETWEEN 30 AND 40 MPH. I HAD MY MECHANIC (NOT THE DEALER) TRY TO EXAMINE THE NOISE WHEN HE DID MY ROUTINE 30K MILE SERVICE. THE NOISE WAS SO FAINT HE WAS NOT ABLE TO DETECT IT. HE WASN'T ABLE TO FIND ANY MAZDA SERVICE BULLETINS THAT INDICATED A PROBLEM TO EXAMINE FURTHER. BESIDES THAT FAINT WHINING NOISE THERE WERE NO OTHER INDICATIONS SUCH A DANGEROUS VEHICLE FAILURE WAS GOING TO OCCUR, AND THE CAR CHECKED OUT FINE AT THAT 30K ROUTINE SERVICE. NOT SURE WHY THE CHECK TIRE PRESSURE LIGHT CAME ON IMMEDIATELY PRIOR TO THE FAILURE BUT THE DEALER SAID THEY "RES

AS I WAS DRIVING DOWN AN ONRAMP TO A FREEWAY, I DEPRESSED THE BRAKE PEDAL AND THE CAR DID NOT RESPOND NORMALLY. I HAD TO PUSH FULL FORCE ON THE PEDAL TO GET THE CAR TO STOP JUST BEFORE REAR ENDING ANOTHER VEHICLE. THIS OCCURRED SEVERAL TIMES AFTER WITHOUT ANY WARNING LIGHT OR ANYTHING. I TOOK THE CAR TO THE DEALER AND FOUND OUT THAT THE BRAKE BOOSTER HAS STOPPED WORKING. THEY ARE GOING TO REPLACE THE BRAKE BOOSTER AND I HAVE TO PAY FOR IT. THIS CAR IS NO LONGER UNDER FACTORY WARRANTY BUT HAS BEEN WELL MAINTAINED BY A MAZDA DEALER ON A REGULAR SCHEDULE.

I PURCHASED A NEW MAZDA CX 9 IN THE FALL OF 2010. AFTER A FEW MONTHS, I NOTICED THE TRACTION CONTROL "TCS OFF" BUTTON ILLUMINATED WHILE DRIVING UP A PAVED INCLINE. AFTER TURNING OFF THE ENGINE AND RESTARTING, THE TCS-OFF BUTTON SHUT OFF. THIS HAPPENED A COUPLE OF TIMES BEFORE MY FIRST SERVICING. I MENTIONED THE ISSUE TO THE MAZDA DEALERSHIP WHEN I WENT IN FOR REGULAR SERVICING. THEY CHECKED IT AND SAID THEY FOUND NO PROBLEM WITH IT. YET THE PROBLEM CONTINUED SPORADICALLY. THE TCS-OFF LIGHT OCCASIONALLY ILLUMINATES ON INCLINED ROADS, IN RAIN OR SNOW, WHEN DRIVING FROM A PAVED TO AN UNPAVED ROAD (OR VICE VERSA). STILL THE DEALERSHIP FOUND NO PROBLEMS DURING SERVICING. NOW IN THE THIRD YEAR OF DRIVING, I MENTIONED THE TCS AGAIN TO THE DEALERSHIP, AND THIS TIME THEY SAID, OH YES, IT IS A PROBLEM.. MAZDA RELEASED A BULLETIN ABOUT IT, SAYING THE TCS NEEDS TO BE REPAIRED FOR $340, AND THE CAR SHOULDN'T BE DRIVEN UNTIL IT'S REPAIRED. YET THIS IS THE CONDITION I'VE ALWAYS DRIVEN IT IN! AND OF COURSE, NOW MY WARRANTY HAS EXPIRED, AND I'M LIABLE FOR REPAIRS EVEN THOUGH THIS PROBLEM EXISTED RIGHT FROM THE VERY BEGINNING. THE DEALERSHIP HAS SAID THEY'D PUT IN A CALL, AND PERHAPS MAZDA WILL COVER AT LEAST PART OF THE COST. IF IT HAD BEEN REPAIRED UNDER WARRANTY, I WOULDN'T BE LIABLE FOR THE REPAIR AND I WOULDN'T HAVE TO PAY FOR THE RENTAL CAR WHILE I'M WAITING. I'LL SEE HOW IT PANS OUT. VERY FRUSTRATING. *TR

I PURCHASED THIS CAR FROM A DEALER THIS YEAR WITH $48,000 MILES. IT WAS IN TIP TOP SHAPE. RECENTLY THE BRAKES ARE NOT WORKING. IT IS NOT THE BRAKE PADS, BUT A HISSING SOUND IN THE LINE AND NO BRAKES. THE COST TO FIX IS AROUND $1500 AND I DON'T HAVE A CREDIT CARD OR THE MONEY TO FIX AT THIS TIME. IN RESEARCHING I AM NOT ALONE WITH THIS PROBLEM. THERE ARE GOING TO BE SOME BAD WRECKS AND PROBLEMS IF THIS IS NOT ADDRESSED ASAP. I PRAY EVERYTIME I HAVE TO GO OUT AND STOP REALLY FAR BEHIND PUMPING AND TRYING TO MAKE THEM WORK. *TR

TL* THE CONTACT OWNS A 2010 MAZDA CX-9. THE CONTACT STATED THAT THE BRAKES WOULD SPORADICALLY FAIL. THE CONTACT HAD TO CONTINUOUSLY PUMP THE BRAKES IN ORDER TO STOP THE VEHICLE. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DETERMINED THAT THE MASTER CYLINDER AND BRAKE BOOSTER NEEDED TO BE REPLACED. THE FAILURE AND THE CURRENT MILEAGE WAS 42,000.

11 YEAR OLD SON WENT TO OPEN THE PASSENGER DOOR UP FRONT AND THE DOOR HANDLE BROKE OFF.(THE DEALERSHIP TOLD ME THAT IT HAPPENED FROM NORMAL WEAR AND TEAR)..SCARY. *TR

BRAKES FAILED DUE TO FAULTY BRAKE BOOSTER. TWO OTHERS AT THE DEALERSHIP HAD THE SAME PROBLEM. MAZDA COULD NOT IMMEDIATELY FIX THE PROBLEM BECAUSE THEY ARE OUT OF BRAKE BOOSTERS AND ARE NOT SURE WHEN ANY WILL BE AVAILABLE. INDICATIONS ARE THAT THIS IS A WIDE SPREAD ISSUE AND SHOULD BE INVESTIGATED. *TR

BRAKE SYSTEM FAILURE INVOLVING MASTER CYLINDER AND BOOSTER. LEAKING INTERNALLY. REPLACEMENT COST OF $1500 RESEARCHED CX9 AND FOUND THIS PROBLEM IS WIDESPREAD AND NOT BEING ADDRESSED.WE HAD A MINOR FENDER BENDER THAT COULD HAVE BEEN MUCH WORSE. MAZDA USA HAS NOT ISSUED ANY BULLETINS AS OF YET. *TR

POWER TRANSFER UNIT LEAKING OIL, I MAY LOSE MY 4WD IF THIS IS NOT FIXED SOON. IT WILL COST $1150.00 TO FIX. THERE IS A HORRIBLE SMELL FROM THE LEAK THAT IS COMING INTO THE VEHICLE. I HAVE HAD 4WD VEHICLES FOR YEARS AND NEVER RAN INTO AN INCIDENT WHERE SOMETHING LIKE THIS HAD TO BE REPLACED. DEALER MADE THIS SEEM LIKE THIS IS A WEAR AND TEAR ISSUE NOT COVERED UNDER ANY WARRANTY. *TR

CPSC: I1360001A. MAZDA CX9 2010. CONSUMER STATED AFTER 36,400 MILES ON CAR, A CATASTROPHIC BRAKE FAILURE OCCURRED ON A TWO YEAR OLD IMPECCABLY MAINTAINED VEHICLE. *LN

TL* THE CONTACT OWNS A 2010 MAZDA CX9. THE CONTACT STATED THAT THE VEHICLE EXHIBITED AN OVERPOWERING BURNING ODOR FROM THE VENTS. IN ADDITION, A LOUD KNOCKING SOUND CAME FROM UNDER THE HOOD. THE CONTACT TOOK THE VEHICLE TO THE DEALER AND WAS TOLD THAT THE TRANSFER CASE NEEDED TO BE REPLACED. THE DEALER TEST DROVE THE VEHICLE AND THE ENGINE SEIZED. THE VEHICLE HAD NOT BEEN REPAIRED. THE FAILURE MILEAGE AND CURRENT MILEAGES WERE 26,900. *TR

CATASTROPHIC BRAKE FAILURE. BRAKES WOULD NOT STOP VEHICLE. VEHICLE TOWED FOR REPAIR. *TR

I NOTICED A STRANGE SMELL IN THE VEHICLE. I DROVE A FEW BLOCKS TO HOME (LUCKILY). ENGINE COMPARTMENT WAS SMOKING AS I PULLED IN THE DRIVEWAY. THIS WAS DIAGNOSED BY A MECHANIC AS A CRACKED TRANSFER CASE. LEAKING FLUID FROM THE CASE WAS THE SOURCE OF THE SMOKE; NOT COVERED UNDER WARRANTY BY MAZDA NOR IS THERE A TSB FOR THE PROBLEM. A QUICK SEARCH SHOWED THAT TRANSFER CASE PROBLEMS ARE COMMON FOR THIS VEHICLE. THIS COULD HAVE BEEN A SERIOUS ROAD HAZARD. *TR

TRANSFER CASE WAS FIRST REPLACED IN JULY 2012 WITH AN OEM PART AND NOW AGAIN 8 MONTHS LATER. LEAKING GEAR OIL, TERRIBLE SMELL COMING INTO COMPARTMENT OF CAR AND ALSO HAD CLUNKING SOUNDS IN FRONT DRIVER SIDE AXEL. *TR

IN JUNE OF 2012 I NOTICED THAT MY BRAKES MADE A HISSING SOUND AT RANDOM TIMES. I BROUGHT THE CAR INTO THE DEALER FOR A COMPLETE SERVICE AND BRAKE CHECK. I WAS TOLD THAT THE BREAKS WERE IN PERFECT CONDITION BUT THEY DID DO A BRAKE FLUSH. THE HISSING CONTINUED AT RANDOM TIME UNTIL THE WEEK OF 1/13/13 AT WHICH TIME THE HISSING WAS AT EVERY OCCASION THE BRAKES WERE ENGAGED. AND ON 1/15/13 THE BRAKES FAILED TO STOP THE VEHICLE. I BROUGHT THE CAR DIRECTLY INTO THE DEALERSHIP AND WAS INFORMED THAT IT WAS A LEAK IN THE BRAKE BOOSTER INTO THE MASTER CYLINDER. AFTER RESEARCHING THIS I HAVE FOUND THAT THIS IS A COMMON MALFUNCTION WITH THE CX9 AND I AM EXTREMELY FRUSTRATED. ALTHOUGH MAZDA ACKNOWLEDGED THE ISSUE ON EARLIER MODELS THEY ARE NOT ACKNOWLEDGING THE ISSUE ON THE LATER MODELS. THEY SHOULD HAVE TO STAND BEHIND THE PARTS AND VEHICLES THAT THEY MAKE. AND WHEN THEY KNOW THAT A CERTAIN PART OR SYSTEM HAS A HISTORY OF FAILING THEY SHOULD TAKE RESPONSIBILITY FOR THE ISSUE INSTEAD OF MAKING THEIR CUSTOMERS PAY FOR THEIR MISTAKES AND FAULTY PARTS. *TR

TELL US WHAT HAPPENED: TRANSFER CASE IS BAD. DEALER SAYS THIS IS A KNOWN PROBLEM AND THAT MAZDA HAS THIS ISSUE WITH CARS DIRECTLY FROM THE FACTORY. KNOWN ISSUES SHOULD BE RECALLED! I BRING MY VEHICLE IN FOR REGULAR MAINTENANCE, I SHOULD NOT HAVE TO BREAK DOWN WITH CHILDREN IN THE CAR FOR A PROBLEM THAT MAZDA KNOWS MY CAR HAS! THE FAILURE IS SO WIDESPREAD THERE IS A NATION WIDE SHORTAGE. *TR

TICKING NOISE WAS HEARD AS I ACCELERATED THE VEHICLE AND AS LEFT TURNS WHERE MADE. THE TICKING NOISE WAS LOUDER WHEN THE ENGINE WAS COLD. MAZDA RECOMMENDED TO REPLACE ENGINE IMMEDIATELY WITHOUT FURTHER INSPECTION. WHEN I ASKED WHAT WAS WRONG WITH THE VEHICLE MAZDA SAID SLUDGE WAS FOUND ON THE DIPSTICK. THEY BLAMED ME THE CONSUMER AND MAZDA WOULD NOT HONOR MY EXTENDED WARRANTY WHICH I PURCHASED THOUGH THEM AT THE TIME OF MY INITIAL PURCHASED OF THE VEHICLE. *TR

SAFETY ISSUE: VEHICLE COULD NOT BE SAFELY DRIVEN. THE POWER LIFT GATE GOT STUCK FULLY OPEN AND WOULD NOT MOVE UP OR DOWN. IT COULD NOT BE SHUT MANUALLY. THE ROD HOLDING THE DOOR WHICH IS PULLED DOWN INTO THE MOTOR WOULD NOT BUDGE. THE VEHICLE COULD NOT BE SAFELY DRIVEN WITH THE HATCH STUCK OPEN LIKE THAT. I HAD TO FIND A WAY TO DISENGAGE THE ROD FROM THE LIFE GATE. STILL, EVEN WITH THE ROD DISENGAGED, IT COULD NOT BE FULLY SHUT. I WAS ABLE TO TIE DOWN THE HATCH HALF WAY SHUT SO THAT I COULD DRIVE IT TO A DEALERSHIP TO BE REPAIRED. BY RESEARCHING SIMILAR PROBLEMS OTHER CX-9 OWNERS HAD, I WAS ABLE TO DETERMINE THAT INSULATION AROUND THE WORM GEAR OF THE MOTOR, BEHIND THE LEFT REAR PANEL, HAD LOOSENED AND GOTTEN CAUGHT IN THE WORM GEAR. THIS IS A PROBLEM THAT IS RELATED TO CONSTRUCTION OF THE VEHICLE, SINCE THE INSULATION IS BEHIND A SECURED PANEL AND NOT ACCESSIBLE BY THE OPERATOR. *TR

I HAVE A 2010 MAZDA CX-9 WITH APPROXIMATELY 41,000 MILES. I HAVE BEEN DILIGENT IN MY MAINTENANCE-ALWAYS WITH A MAZDA DEALER. THE CAR STARTED TO EXHALE SLIGHTLY WHEN BRAKING. THE CAR THEN DID NOT WANT TO BRAKE/STOP WITHOUT PUMPING THE BRAKES REPEATEDLY. I WAS ABLE TO STOP SUDDENLY BUT UNABLE TO STOP WITHOUT AMPLE WARNING AT STOP SIGNS, ETC. THE VEHICLE WAS TAKEN TO MAZDA DEALERSHIP WHERE THEY TOLD ME THAT THE VACUUM BOOSTER AND MASTER CYLINDER WERE DEFECTIVE. I WAS NOT ALLOWED TO DRIVE THE CAR BECAUSE IT WAS NOT SAFE. THEY THEN TOLD ME THE NEXT MORNING THAT MAZDA/DEALERSHIP FOUND NO WARRANTY COVERING SUCH A MALFUNCTION/FACTORY DEFECT B/C I HAD PASSED THE 36,000 MILES MARK. I WILL HAVE TO PAY $839 FOR A REPAIR TO DRIVE MY CAR THAT IS AN ISSUE WITH THE MANUFACTURING OF MY CAR. THE DEALER TOLD ME I MUST CONTACT MAZDA USA DIRECTLY TO SEE IF THEY WILL PAY FOR IT-OTHERWISE I AM RESPONSIBLE. I HAVE READ OTHER COMPLAINTS AND AN ARTICLE IN THE WALL STREET JOURNAL BOTH SITTING THE EXISTENCE AND EXPERIENCE OF THIS MALFUNCTION. THE NHTSA WAS SAID TO BE INVESTIGATING THE ISSUE. MAZDA SHOULD BE FORCED TO RECALL THE VEHICLES AND FIX THE MALFUNCTIONING BRAKE SYSTEM. IT IS NOT THE FAULT OF THE CONSUMER BUT OF THE CAR MANUFACTURER. *TR

I WAS DRIVING ON A STREET WITH A 25 MPH SPEED LIMIT WHEN ALL OF A SUDDEN THE CAR HESITATED AND MADE SOME WEIRD NOISES. I CONTINUED TO PULL OVER TO GET OUT OF THE WAY WHEN THERE WAS A HUGE BANG AND THE CAR CAME TO AN SUDDEN STOP. I WAS ABLE TO GET TO THE SIDE OF THE ROAD. SMOKE WAS COMING OUT OF THE ENGINE AREA AND THE CAR SMELLED TERRIBLE. I JUMPED OUT, GOT MY DOG OUT AND CALLED 911. THE FIRE DEPARTMENT AND POLICE CAME. FOUND METAL PARTS ALL OVER THE ROAD. SMOKE WAS MAINLY DUE TO OIL THAT WAS ALL OVER THE ENGINE AND BOTTOM OF CAR. RIGHT NOW THE INITIAL DIAGNOSIS IS THAT THE TRANSFER CASING BLEW ALONG WITH A VARIETY OF OTHER PARTS. THANK GOODNESS I WAS NOT ON THE FREEWAY. ADDITIONALLY, I WAS LUCKY THAT THE LARGE PARTS THAT BLEW OFF THE CAR DID NOT PUT A HOLE IN THE BOTTOM OF MY CAR OR DAMAGE SOMEONE ELSE'S CAR. *TR

TL* THE CONTACT OWNS A 2010 MAZDA CX-9. THE CONTACT STATED THAT WHILE THE VEHICLE WAS PARKED HE ACCIDENTALLY LOCKED THE DOORS WITH THE REMOTE KEY AND THE PASSENGER WAS LOCKED IN THE VEHICLE. THE DOORS FAILED TO UNLOCK MANUALLY FROM THE INSIDE OF THE VEHICLE. THE VEHICLE WAS TAKEN TO THE DEALER WHO WAS UNABLE TO DIAGNOSE THE FAILURE. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE WHO FILED A REPORT AND DID NOT OFFER ANY ADDITIONAL ASSISTANCE. THE FAILURE MILEAGE WAS 35,000 AND THE CURRENT MILEAGE WAS 35,572.

TL* THE CONTACT OWNS A 2010 MAZDA CX-9. THE CONTACT STATED THAT WHILE DRIVING 25 MPH, THERE WAS A DELAY IN STOPPING DISTANCE ONCE THE BRAKES WERE ENGAGED. THE CONTACT MENTIONED THAT HE HAD TO DEPRESS THE BRAKES REPEATEDLY IN ORDER TO BRING THE VEHICLE TO A COMPLETE STOP. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO DIAGNOSED THAT THE VACUUM BOOSTER AND MASTER CYLINDER WERE DEFECTIVE AND NEEDED TO BE REPLACED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 50,000 AND THE CURRENT MILEAGE WAS 50,040.

THE FIRST TIME I EXPERIENCED THIS TERRIFYING ORDEAL WAS IN NOVEMBER OF 2011. SINCE THEN, I HAVE HAD IT HAPPEN TWO MORE TIMES. THE CAR ACCELERATES OF UP TO SPEEDS OF 90 MPH WITHOUT WARNING . ALL 3 INCIDENTS HAVE HAPPENED ON THE HIGHWAY. THE BRAKES SLOW IT DOWN, BUT DO NOT STOP IT. ALL 3 TIMES, I'VE BEEN LUCKY ENOUGH TO GET THE CAR TO THE SHOULDER AND RIDE DOWN THE MEDIAN , PUSHING THE EMERGENCY BREAK IN AND AT ONE POINT PUSHING IT INTO PARK. MAZDA KNOWS ABOUT THIS. THEREFORE THEY ARE LIABLE. MAZDA WILL TELL YOU IT'S A THROTTLE PROBLEM, THEY WILL TELL YOU THERE IS NO WEAR ON THE BRAKES....WELL, THAT'S BECAUSE WHEN THE CAR DOES THIS UNEXPECTED ACCELERATION, THE BRAKES ONLY GO PART WAY..ALMOST LIKE PUSHING AGAINST AIR. THIS IS A SERIOUS PROBLEM WITH THE COMPUTER AND POSSIBLY THROTTLE COMBINED. MY CAR IS NOT FIXED, IT'S ALSO DOING OTHER STUFF. MAZDA WANTS ME TO KEEP THIS CAR AND DRIVE IT. THEY ARE GIANTS, SO THE LITTLE PERSON LIKE ME DOES NOT MATTER TO THEM IT'S THE $$$$. BUT WHEN SOMEONE DIES, IT WILL COST THEM $$$$$$$$$$. THERE NEEDS TO BE A RECALL. I HOPE MORE PEOPLE COME FORWARD. IT COULD SAVE YOUR LIFE OR/AND SOMEONE YOU LOVE AND OTHER DRIVERS ON THE ROAD WHO ARE IN DANGER OF YOU HURTING/KILLING THEM. MY MAZDA DEALERSHIP HAVE WONDERFUL PEOPLE WHO WORK THERE. THEY ARE VERY UNHAPPY WITH MAZDA NOT TAKING CARE OF THIS PROBLEM. I WANT TO MAKE THIS CLEAR, IT'S MAZDA CORP THAT IS AWARE AND DOING NOTHING AND THEY HOLD THE MAZDA DEALERS HOSTAGE. *TR

TL* THE CONTACT OWNS A 2010 MAZDA CX-9. THE CONTACT WAS DRIVING 50 MPH WHEN THE VEHICLE SURGED FORWARD UNCONTROLLABLY. THE CONTACT WAS ABLE TO EVENTUALLY STOP THE VEHICLE AND THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER WHERE THEY WERE UNABLE TO DIAGNOSE THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND OFFERED NO ASSISTANCE. THE FAILURE MILEAGE WAS 17,000. THE VIN WAS UNAVAILABLE.

TL* THE CONTACT OWNS A 2010 MAZDA CX-9. WHILE DRIVING APPROXIMATELY 10 MPH, THE VEHICLE UNCONTROLLABLY ACCELERATED INTO ONCOMING TRAFFIC. THE BRAKES WERE APPLIED REPEATEDLY WHEN SUDDENLY THE VEHICLE CAME TO A STOP. THE VEHICLE WAS TOWED TO AN AUTHORIZED DEALER FOR DIAGNOSIS WHERE THE TECHNICIAN WAS UNABLE TO LOCATE THE PROBLEM. THE MANUFACTURER WAS NOTIFIED OF THE UNINTENDED ACCELERATION FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 18,000.

WAS DRIVING ON I-495E IN MARYLAND BETWEEN EXITS 28 AND 29. CHANGED LANES AND PUT FOOT DOWN ON GAS PEDAL TO ACCELERATE. SUDDENLY FELT LIKE GAS PEDAL WAS STUCK AND THAT BRAKING COULD ONLY SLOW BUT NOT STOP ACCELERATION. MOVED OVER A FEW LANES TO RIGHT SHOULDER AND AFTER CONTINUED FAILURE OF BRAKES TO STOP ACCELERATION (AND CONSIDERABLE ENGINE TORQUE) BEGAN TO APPLY EMERGENCY BRAKE. SLOWED ACCELERATION FURTHER BUT STILL COULD NOT BRING CAR TO A FULL STOP. FINALLY PUT CAR INTO NEUTRAL AND CAME TO A STOP. HAD TOWED TO NEAREST MAZDA DEALER, YET AFTER SEVERAL DAYS OF TESTING THEY FOUND NOTHING WRONG WITH CAR AND COULD NOT REPLICATE. CLAIMED MANUFACTURER HAD NO RECORD OF SIMILAR PROBLEMS WITH THIS MODEL. ONLY THING THEY COULD THINK OF WAS THAT ALL-WEATHER FLOOR MAT MIGHT HAVE SLID OVER PEDAL AND KEPT IT DEPRESSED. *TR

THE AUTOMATIC DIMMER SWITCHED TO LOW LIGHT SETTING IN BROAD DAYLIGHT FOR NO APPARENT REASON RESULTING IN A DARK INSTRUMENT PANEL. DRIVER HAD TO PULL ASIDE ON A BUSY HIGHWAY TO TRY TO RESTORE DAYTIME LIGHTING. THIS IS THE SAFETY ASPECT - LOSS OF PANEL INFORMATION WHILE DRIVING CAUSING AN EMERGENCY PULL OFF AND A DISTRACTION TO THE DRIVER. THE LIGHT SENSOR CONTROLLING BOTH THE PANEL AND THE DAY/NIGHT CAR LIGHTS WAS SET TO STANDARD - DEFAULT SETTING. IT APPEARS THAT THIS SETTING IS TOO HIGH. AFTER INSISTING WITH THE DEALERSHIP, IT WAS FOUND THAT THE SENSOR IS PROGRAMMABLE. IT WAS SET THEN TO LOW, WHICH SEEMED TO HAVE FIXED THE PROBLEM. THIS STILL NEEDS TO BE ADDRESSED BY THE MANUFACTURER IN A SYSTEMIC MANNER FOR THE SAFETY OF OTHER DRIVERS.

THERE IS A TICKING NOISE IN THE ENGINE WHEN IDLE. WHEN THE ENGINE IS COLD THE NOISE IS LOUDER. THE VEHICLE HAS BEEN TAKEN TO THE DEALER. THE DEALER STATES THAT THERE IS NOTHING TO FIX. THE DEALER IS INFORMING ME THAT IT WAS THE CHARACTERISTICS OF THE VEHICLE AND IT WAS INSPECTED BY A MAZDA ENGINEER. THE ENGINEER CLAIMS THAT THIS IS A NORMAL SOUND FOR THIS VEHICLE AND ENGINE. I EXPLAINED THAT I HAD NOT HEARD THIS ON ANY OF THE OTHER CX-9'S I DROVE. THE DEALER TRIED TO CLAIM IT WAS DUE TO DIFFERENT ENGINES. I INFORMED THE DEALER THAT THEY ALL HAD THE SAME ENGINE. AGAIN, HE SAID THERE IS NOTHING TO FIX (THE TICKING IS NORMAL). I INFORMED THE DEALER THAT IT IS THE OPINION OF ANOTHER AUTOMOBILE SHOP THAT THIS SOUND IS NOT NORMAL AND SHOULD NOT BE OCCURRING (I WAS AT THE OTHER SHOP THE WEEK PRIOR). THE DEALER RESPONDED BY SAYING THE OTHER SHOP IS NOT A MAZDA DEALERSHIP AND THEIR OPINION DOES NOT MATTER.

AT 8AM JANUARY 12, 2011 I WAS DRIVING TO WORK IN A BLIZZARD. I FELT A SLIGHT PAIN/PINCH FROM MY SEAT AND QUICKLY MOVED THINKING IT WAS SOMETHING FROM MY POCKET. I RESUMED DRIVING AND AGAIN FELT A MUCH GREATER PAIN CAUSING ME TO SWERVE AND CAUSE A NEAR COLLISION. VERY FRIGHTENED, I JUMPED OUT OF THE CAR (MID TRAFFIC IN BLIZZARD) TO FIND MY SEAT SCORCHED THROUGH APPARENTLY FROM THE SEAT WARMER. THIS IS VERY CONCERNING. FORTUNATELY I WAS NOT DRIVING AT A GREATER SPEED AS IT COULD HAVE BEEN CRITICAL OR FATAL. WHAT DO I DO ABOUT THE SEAT? ALTHOUGH I HAVE TURNED THE WARMER OFF, I AM STILL AFRAID TO DRIVE THIS VEHICLE. *TR

WHILE DRIVING AT INTERSTATE ROAD SPEED OF 65MPH ON A CLEAR NON-RAINING, 65 DEGREE DAY MY TRACTION CONTROL SYSTEM LIGHT TURNS ON AND STAYS ON FOR THE DURATION OF THE RIDE. *TR

TL*THE CONTACT OWNS A 2010 MAZDA CX9. THE CONTACT STATED THAT WHENEVER SHE MADE A TURN, HER VISIBILITY WAS SEVERELY AFFECTED BECAUSE OF THE PLACEMENT AND SIZE OF THE REARVIEW MIRRORS. THE VEHICLE HAD NOT BEEN INSPECTED OR REPAIRED. THE FAILURE MILEAGE WAS 0 AND THE CURRENT MILEAGE WAS APPROXIMATELY 13,000.

TL*THE CONTACT OWNS A 2010 MAZDA CX-9. THE CONTACT STATED THAT THERE WAS A LOUD TICKING NOISE IN THE ENGINE. ONCE THE ENGINE WAS COLD THE NOISE BECAME EXTREMELY LOUD BUT WHEN IT WAS WARM THE NOISE CEASED. THE VEHICLE WAS TAKEN TO THE DEALER TWICE. THE FIRST TIME THEY STATED THAT THEY CORRECTED THE PROBLEM BY DOWN LOADING INFORMATION FROM THE COMPUTER IN REFERENCE TO THE PCM AND TOLD HER THAT IT WAS CORRECTED. WHEN SHE DROVE THE VEHICLE IT CONTINUED TO MAKE NOISE. SHE THEN RETURNED THE VEHICLE BACK TO THE DEALER AND THEY WERE DIAGNOSING THE FAILURE FOR AN ENTIRE WEEK. THE DEALER INFORMED HER THAT IT WAS THE CHARACTERISTICS OF THE VEHICLE AND IT WAS INSPECTED BY MAZDA ENGINEERS. THE ENGINEERS TOLD HER THAT IT WAS A NORMAL SOUND COMPARED TO OTHER VEHICLES AND THAT HER VEHICLE WAS JUST LOUDER THAN THE OTHERS. SHE DID NOT CALL THE MANUFACTURER BECAUSE THE DEALERSHIP TOLD HER THAT THEY WOULD CONTACT THEM. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 1,500.

NEW VEHICLE WITH DEAD BATTERY ON FOUR SEPERATE OCCASIONS. TOOK TO DEALERSHIP, BATTERY REPLACED. CHILD COMPLAINED THAT SEAT WAS HOT. NEXT DAY DEALER NOTIFIED AND CAR BROUGHT IN T ODEALERSHIP. A LOANER VEHICLE WAS RECEIVED. I WAS NOTIFIED HEATED SEATS WITH RECALL AND WOULD BE DISCONNECTED AT THIS TIME. THIS ALL OCCURED IN A TWO WEEK PERIOD IN JANUARY. MARCH 17 TOOK CAR BACK TO DEALERSHIP TO HAV RECALL ON HEATED SEATS FIXED. MARCH 25TH ATTEMPTED TO USE HEATED SEATS, DID NOT WORK. MAR 30TH VEHICLE BACK TO DEALERSHIP. HEATED SEATS WORKING AFTER THEY LOOKED AT VEHICLE. MARCH 31ST RIDING TO WORK IN PASSANGER SEAT, HEATED SEAT OPTION OFF, SEAT WARM TO TOUCH, BECAME HOTTER AND HOTER THEN WARM DURING 1 HOUR COMMUNTE.
