2012 MAZDA CX-9 Complaints

I WAS ON THE INTERSTATE (DRIVING 60+MPH) AND THE CAR IN FRONT OF ME SLAMMED ON THEIR BRAKES FOR AN UNKNOWN REASON. I TRIED TO USE MY BRAKES BUT THEY WERE ROCK HARD AND THE PEDAL WOULDN'T DEPRESS. I WAS FORCED TO SWERVE TO THE RIGHT, STILL HAVING NO BRAKES, AND BARELY MADE IT OVER 3 LANES TO THE SHOULDER OF THE ROAD. IN DOING SO, I CAUSED TOTAL CHAOS AROUND ME, CAUSED A TRACTOR TRAILER TO START TO JACKKNIFE, WHICH CAUSED A CHAIN REACTION BEHIND HIM. IT WAS A TOTAL MIRACLE THAT NO ACCIDENTS WERE CAUSED AND NO ONE WAS KILLED. I CALLED MY MECHANIC FROM THE SIDE OF THE ROAD, HYSTERICAL. HE LOOKED IN HIS DATABASE AND FOUND THAT MAZDA HAD KNOWN ISSUES WITH THEIR POWER BRAKE BOOSTER. I SUBSEQUENTLY FOUND A LETTER FROM MAZDA INSTRUCTING OWNERS "IF YOUR VEHICLE IS FUNCTIONING PROPERLY, THERE IS NO NEED TO CONTACT YOUR DEALER." ARE YOU KIDDING ME???? MY BRAKES WERE FINE UNTIL THEY WEREN'T, THEN I NARROWLY AVOIDED BEING KILLED OR CAUSING THE DEATH OF ANOTHER BECAUSE APPARENTLY MAZDA'S BODY COUNT WASN'T HIGH ENOUGH TO ISSUE A RECALL.

I WAS DRIVING SLOWLY ABOUT 30MIPH AND BEGAN HEARING A HISSING NOISE WHEN I DEPRESSED THE BRAKE PEDAL. ONCE I PULLED INTO MY DRIVEWAY A SMALL INCLINE, AND PUSHED THE BRAKE PEDAL IT WAS VERY TIGHT AND STOPPED AT A POINT, BUT WOULD NOT GO FURTHER, TRIED SHIFTING DIFFERENT GEARS. FINALLY BRAKE DEPRESSED. HISSING HAS CONTINUES, VERY STIFF BRAKE PEDAL

TL* THE CONTACT OWNS A 2012 MAZDA CX9. THE CONTACT STATED THAT WHILE DRIVING AT AN UNDISCLOSED SPEED, THE VEHICLE SHUT-OFF WITH AN UNKNOWN WARNING LIGHT ILLUMINATED. THE VEHICLE WAS TAKEN TO TWO INDEPENDENT MECHANICS WHO DIAGNOSED THAT WATER ENTERED THE VEHICLE AND CAUSED THE CORROSION OF THE FRONT SUSPENSION BALL JOINT. THE DEALER WAS NOT CALLED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 83,000.

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.

BRAKE BOOSTER ON VEHICLE WENT OUT WHILE DRIVING, HARD TO ENGAGE BRAKE AND SLOW VEHICLE TO A STOP.

TL* THE CONTACT OWNS A 2012 MAZDA CX-9. THE CONTACT STATED THAT WHILE DRIVING, AND MAKING A TURN AT 5 MPH, THE BRAKES WERE SQUISHY AND THE VEHICLE FAILED TO STOP. THERE WERE NO WARNING LIGHTS ILLUMINATED. THE VEHICLE WAS TAKEN TO BOB MOORE MAZDA (13045 N. KELLEY AVE, OKLAHOMA CITY, OK 73131 (405) 775-7000) TO BE DIAGNOSED. THE CONTACT WAS INFORMED THAT BRAKE MASTER CYLINDER NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS CONTACTED AND STATED THAT THE EXTENDED WARRANTY HAD EXPIRED. THE FAILURE MILEAGE WAS 75,000.

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.

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
