What 221 owners told NHTSA about the 2012 Mazda Cx-90

MY WIFE WAS DRIVING DOWN A CITY STREET WHEN THE CAR COMPLETELY SHUT DOWN AND LOST ALL POWER. LUCKILY, SHE WAS ABLE TO STOP WITHOUT CAUSING AN ACCIDENT. WE HAD CAR TOWED TO AN INDEPENDENT MECHANIC. AFTER INSPECTION WE WERE TOLD THE WATER PUMP HAD FAILED CAUSING COOLANT TO LEAK INTO THE ENGINE AND CAUSED COMPLETE ENGINE FAILURE. WE WERE QUOTED $8K-$10K TO REPLACE THE ENGINE. THE 2012 MAZDA CX-9 ONLY HAD 99K MILES, BUT UNFORTUNATELY OUR EXTENDED WARRANTY EXPIRED A FEW YEARS AGO, SO MAZDA WAS OF NO HELP. WE WERE LEFT TO JUNK OUR CAR FOR A FRACTION OF WHAT IT'S VALUE SHOULD HAVE BEEN. APPARENTLY THIS IS A KNOWN ISSUE AND WE WILL BE JOINING THE CURRENT CLASS ACTION LAWSUIT AGAINST MAZDA.

WHILE PULLING INTO MY GARAGE AT LOW SPEED, MY POWER BRAKES FAILED. I HAD TO PRACTICALLY STAND ON THE BREAK PEDAL TO GET THE VEHICLE TO STOP, BARELY STOPPING BEFORE HITTING THE FRIDGE IN MY GARAGE.THE VEHICLE WAS TOWED FOR SERVICE AND THE PROBLEM DIAGNOSED AS THE FAILURE OF THE BRAKE VACUUM BOOSTER.

NHTSA ODI 11351038

BRAKE PEDAL HAS BECOME HARDER THAN USUAL TO DEPRESS AND THE CAR DOES NOT START STOPPING UNTIL THE BRAKE PEDAL IS DEPRESSED HARDER AND FURTHER DOWN. ALSO THERE IS A HISSING NOISE ONCE THE CAR STOPS AND THE BRAKE PEDAL GOES FURTHER TO THE FLOORBOARD. ONCE STOPPED AND SITTING THE CAR WILL LURCH AS IF IT HAS BEEN HIT IN THE REAR END. THIS ALL HAPPENS ON ANY TYPE OF ROADWAY. THIS HAS BEEN GOING ON FOR ABOUT TWO MONTHS AND GETTING MORE PRONOUNCED.

WHEN APPLYING BRAKE, HEAR HISSING SOUND DOWN AT FEET. HARD TO STOP, FEELS LIKE PEDAL IS PUSHING BACK. THIS HAPPENS AT ALL SPEEDS, EVEN WHEN PUTTING CAR INTO GEAR FROM PARK. IT HAS BEEN ONGOING FOR ABOUT 2 WEEKS. MECHANIC ADVISED IT IS THE BRAKE BOOSTER.

I WAS DRIVING HOME WITH THE FAMILY AFTER VIEWING SOME HOUSE. EVERY TIME I WOULD STEP ON THE BRAKE PEDAL I WOULD HEAR A HISSING FROM THE BRAKE. BEEN HAPPENING FOR ABOUT A MONTH NOW BUT, WITH THE PANDEMIC GOING ON I JUST DON'T HAVE TIME TO DIAGNOSE THE PROBLEM. WHEN I PRESS ON THE BRAKE IT WOULD STOP LIKE NORMAL WITH AIR HISSING. THE NEXT DAY THE BRAKE PEDAL WOULD FEEL VERY HARD TO PRESS DOWN. LIKE AS IF YOU BEEN PUMPING YOUR BRAKE WHEN THE CAR OFF AND WHEN YOU TURN YOUR CAR ON THE PRESSURE WOULD BE RELEASED. NOT TODAY, IT STAYED HARD AND HARD TO STOP. I HAD TO PRESS THE BRAKE VERY HARD AS IF PRESSING THE BRAKE PEDAL ALL THE WAY DOWN TO THE FLOOR TO MAKE THE CAR STOP. JUST STOPPING AT A RED LIGHT, STOP SIGN, OFF THE HIGHWAY, AND TRAFFIC WAS A CHALLENGE. I'LL EVENTUALLY STOP BUT IN THE MIDDLE OF A INTERSECTION OR IN THE BACK OF A CAR. IF I HAD TO BRAKE BECAUSE SOMEONE TURNED IN FRONT OF ME, I WOULD OF JUST HIT THEM FULL SPEED BECAUSE MY BRAKE BOOSTER FAILURE TO PRODUCE ENOUGH PRESSURE TO ENGAGE MY BRAKES TO STOP. THE DAY THE BRAKE BOOSTER HAPPEN TO FAILURE COMPLETELY IS WHEN WE HAD A FAMILY TRIP DOWN TO THE WISCONSIN DELLS OVER THE JULY 4TH WEEKEND. SINCE BRAKE BOOSTER WASN'T A RECALL BUT AN EXTENDED WARRANTY AND ENDED MARCH 2015 OR 90,000 MILES. MAZADA WOULD CHARGE ME FULL PRICE TO GET IT FIXED. I WOULD NOT FELL SAFE DRIVING IT TO THE DEALER AND MAZADA DOESNT COVER TOWING UNLESS ITS WITHIN 3 YEARS. SO THEY'LL TOW ANYTHING IN THE 2017 AND NEWER. 2012 MAZADA CX-9 WITH 112,500. OWNED IT FOR EXACTLY 3 TO DATED

PURCHASED FROM A CERTIFIED PRE-OWNED MAZDA DEALER....I EXPERIENCED, WITH NO WARNING, MY BRAKES BECOME HARD TO PRESS. IT HAPPENS IN REVERSE, COMING OFF CRUISE, SLOW/FAST SPEED, ETC. I HAVE TO USE AN EXTRAORDINARY AMOUNT OF EFFORT TO PRESS THE BRAKES AND BRING THE CAR TO A STOP. IF SOMEONE PULLS OUT IN FRONT OF ME, THERE IS NO GUARANTEE I WOULD BE ABLE TO OPERATE THE BRAKES QUICKLY ENOUGH TO AVOID AN ACCIDENT. I HAVE CHILDREN I TRANSPORT AND IT IS CONCERNING FOR ME AS A MOM ESPECIALLY. A FEW TIMES THE PEDAL WILL 'RELEASE' AND OPERATE NORMALLY AFTER THE EXTRA PRESSURE IS APPLIED WHICH CAUSES THE CAR TO JERK TO A STOP BECAUSE THE BRAKES WERE BEING PRESSED VERY HARD. MOST TIMES, EXTRA PRESSURE IS REQUIRED THE ENTIRE TIME. THIS IS A MAJOR SAFETY CONCERN AND AN ISSUE I AM AWARE IS COMMON IN THIS MODEL. MAZDA EXTENDED THIS WARRANTY TO 90K AND 7 YEARS BACK IN 2015; HOWEVER, THIS DOES NOT COVER USED CAR PURCHASERS. THE ISSUE WAS NOT DISCLOSED TO ME IN MY PURCHASE DATE OF 12/12/2016. HAD I KNOWN THIS MAJOR COMPONENT COULD FAIL, I WOULD HAVE MADE A MORE EDUCATED DECISION ON WHETHER TO PURCHASE OR REQUEST THE FAULTY SYSTEM BE CORRECTED.

IN OCT. 2019 MY CX9 STOPPED WHILE BEING DRIVEN. FOUND OUT THE WATER PUMP (WHICH IS INSIDE THE ENGINE) HAD GONE OUT AND DESTROYED MY ENGINE. THIS IS A KNOWN PROBLEM OF WHICH MAZDA HAS FAILED TO MAKE THEIR CONSUMERS AWARE. I PURCHASED THIS CARE NEW AND ALL OF MY SERVICES HAD BEEN HANDLED BY MAZDA. NO-ONE TOLD ME ABOUT THIS PROBLEM AND I STILL HAD TO PAY JUST OVER 4K TO GET A NEW ENGINE OF THE SAME STUPID DESIGN PUT IN MY CAR. THIS IS VERY DANGEROUS PROBLEM. HOW MANY MAZDA DRIVERS HAVE BEEN INJURED OR KILLED IN CRASHES BECAUSE THE WATER PUMP DESTROYED THE ENGINE ON A FREEWAY AND THE CAR CEASING TO MOVE WAS THE CAUSE OF AN ACCIDENT THAT TOTALED THE CAR AND AS A RESULT WENT UNDETECTED? THE ENGINES NEED TO BE RECALLED.

CALLED MAZDA AND SAME RESPONSE 'NOT OUR PROBLEM, IT'S OUT OF WARRANTY'. *TR

I AM NOW EXPERIENCING WHAT MAZDA MAILED OWNERS PREVIOUSLY (SEE ATTACHED SSP93 OWNERS NOTICE) REGARDING "POWER BRAKE UNIT WARRANTY EXTENSION PROGRAM SSP 93 2007-2013 MAZDA CX-9". I STRONGLY BELIEVE THAT THIS IS A SAFETY ISSUE SINCE I FIND MYSELF RUNNING STOP SIGNS WHEN I TRY TO STOP THE VEHICLE AT AN INTERSECTION. I KNOW THAT MAZDA EXTENDED THE WARRANTY TO 7 YEARS ON IT'S SSP93 BULLETIN. BUT WHAT HAPPENS TO OWNERS LIKE MYSELF WHO DO NOT FALL WITHIN THAT TIME-FRAME AND ARE NOW EXPERIENCING THIS SAFETY ISSUE? IT IS UNCONSCIONABLE, THAT SINCE MAZDA HAS ACKNOWLEDGED THIS PROBLEM, THAT THE OWNER LIKE MYSELF GETS STUCK WITH THIS SAFETY PROBLEM CONCERNING FAILURE OF THE BRAKING SYSTEM ON THE CX-9. PLEASE ADVISE. THANKS.

BRAKE BOOSTER FAILED. THIS IS A KNOWN ISSUE TO MAZDA. MAZDA SAID TO BRING INTO DEALER FOR ASSESSMENT AND CONSIDERATION FOR GOODWILL WARRANTY REPLACEMENT. DEALER DETERMINED BRAKE BOOSTER FAILED AND MAZDA THEN DENIED GOODWILL CLAIM. I PAID DEALER TO FIX THE ISSUE. THIS IS A MAJOR SAFETY ISSUE AND SHOULD HAVE BEEN RECALLED, NOT GRANTED AN EXTENDED WARRANTY.

BRAKE PEDAL ACTION FEELS SPONGY, SOFT. REQUIRES EXTRA FORCE TO STOP THE CAR WHEN MOVING ON CITY STREETS.

SO DISAPPOINTED IN NHTSA FOR NOT REQUIRING MAZDA TO RECALL THE BRAKE BOOSTER FAILURE! NHTSA'S INVESTIGATION INTO THE BRAKE BOOSTER FAILURE WAS CLOSED WHEN MAZDA AGREED TO AN EXTENDED WARRANTY FOR THIS MANUFACTURING SAFETY DEFECT. HAD THE NHTSA PUSHED FOR A RECALL NOTICE, WE WOULD HAVE BEEN ALERTED TO THIS SAFETY DEFECT AND COULD HAVE HAD IT REPAIRED (IT IS KNOWN TO FAIL AROUND 62,000 MILES). WE CONTACTED MAZDA TODAY ABOUT THE WARRANTY ONLY TO BE TOLD OUR VEHICLE WARRANTY EXPIRED LESS THAN 3 MONTHS AGO, RESULTING IN MAZDA'S REFUSAL TO COVER A KNOWN SAFETY DEFECT. MAZDA'S LACK OF COMMITMENT TO RESOLVING THIS SAFETY ISSUE IS SHOCKING. NHTSA'S ACCEPTANCE OF MAZDA EXTENDING ITS WARRANTY FOR THIS KNOWN SAFETY ISSUE IS DISHEARTENING AS WELL. A MANUFACTURING DEFECT IS A MANUFACTURING DEFECT; THE PROBLEM SHOULD HAVE BEEN ADDRESSED WHEN IT FAILED OR, AT THE VERY LEAST, RECALLED AND REPLACED. A TIME LIMIT SHOULD NOT HAVE BEEN AN OPTION FOR A SAFETY ISSUE (OR AN OUT FOR MAZDA). PERHAPS IT IS TIME FOR NHTSA TO REOPEN ITS INVESTIGATION TO PROTECT THE CONSUMERS AGAINST A KNOWN SAFETY DEFECT. MAZDA CERTAINLY DOESN'T BACK IT'S PRODUCT WHEN IT COMES TO SAFETY ISSUES!

I WAS TURNING RIGHT INTO A PARKING SPACE WITH MY FOOT ON THE BRAKE, WHEN THE CAR SUDDENLY ACCELERATED. THE ENGINE REVVED UP AND THE CAR DARTED FORWARD. FOR A SPLIT SECOND I LIFTED MY FOOT TO MAKE SURE I WAS NOT PRESSING ON THE ACCELERATOR, AND IMMEDIATELY PUSHED BACK DOWN ON THE BRAKE AS HARD AS I COULD; THE CAR CONTINUED TO SPEED FORWARD. INSTINCTIVELY I KEPT THE WHEEL TURNED TO THE RIGHT TO AVOID CRASHING INTO THE BUILDING IN FRONT OF ME AS THE CAR JUMPED THE CURB, BUT I HIT 2 PARKED CARS. ONCE I WAS ALMOST STOPPED BY HITTING THE 2 PARKED CARS, I QUICKLY TURNED THE KEY OFF AND PUT THE CAR IN PARK. I HAVE NEVER EXPERIENCED THIS ISSUE BEFORE; AND LET ME TELL YOU, I WAS TERRIFIED. I HAVE PICTURES THAT SHOW TIRE MARKS EITHER FROM THE CARS ACCELERATION OR DRAGGING THE BACK WHEELS FROM PUSHING ON THE BRAKE.

APPLYING BRAKES FOR 1-2 SECONDS RESULTED IN NO IMMEDIATE STOPPING, ONLY RESISTANCE FROM THE PEDAL. AFTER 1-2 SECONDS, THE BRAKES WERE AGGRESSIVLY APPLIED. THIS RESULTED IN "RUNNING A STOP SIGN" AND STOPPING THE IN MIDDLE OF AN INTERSECTION. THIS OCCURRED ON A CITY STREET MULTIPLE TIMES BEFORE GETTING THE CAR TO A REPAIR SHOP. ON HIGHWAYS, BRAKING HAD TO BEGIN WELL IN ADVANCE TO AVOID POSSIBLE CRASHES. WE HAD TO HAVE THE MASTER CYLINDER AND BRAKE BOOSTER REPLACED. THE VEHICLE HAS 55K MILE ON IT.

WE OWN A 2011 MAZDA CX7 AND A 2012 MAZDA CX9, THE MOTORS IN THE DRIVERS AND PASSENGER SIDE WINDOWS OF BOTH CARS WHEN OUT WITHIN A 6 MONTH PERIOD OF TIME. THE WARRANT ON THE CARS WERE OUT AT 36K MILES AND IN 2014. THE MOTORS BOTH STOPPED WORKING PAST THIS PERIOD TIME BUT HAVE READ THIS HAS HAPPENED ON THESE SAME VEHICLES. THE WINDOWS GO DOWN BUT START MAKING A LOUD CLICKING SOUND AND WILL NOT GO BACK UP WITH OUT HOLDING YOU HAND ON IT, CREATING A VERY DANGEROUS SITUATION WITH SMALL CHILDREN.
