2010 MAZDA CX-9 Complaints

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 "RESET" IT WHEN THEY REPLACED THE TRANSFER CASE. THE DEALER WAS VERY PROMPT AND PROFESSIONAL IN THEIR RESPONSE AND TREATED US VERY WELL. BUT I DO FEEL THIS ISSUE IS SO SERIOUS WE SHOULD HAVE RECEIVED NOTICE FROM MAZDA WITH A REQUEST TO GET THE TRANSFER CASE EXAMINED EARLIER. *TR

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
