2012 MAZDA CX-9 Complaints

2012 MAZDA CX-9. CONSUMER WRITES IN REGARDS TO BRAKE POWER BOOST UNIT FAILURE. *LD THE CONSUMER STATED THAT WHEN PRESSING THE BREAK PEDAL THERE IS A HISSING AND THUNK NOISE. THE ENGINE WOULD STALL. THE DEALERSHIP AND MANUFACTURER WERE NOTIFIED, BUT DENIED ASSISTANCE.*JS

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

WHEN PUSHING THE BRAKES THE PEDAL IS 'HARD' AS IF THE PEDAL WAS ON THE FLOOR THERE'S A HISSING NOISE LIKE AIR IS LEAKING. IF YOU NEED TO MAKE A SUDDEN STOP IT DOES NOT HAPPEN THE BRAKES ARE SO HARD THE CAR WON'T STOP!! THIS DEFECT HAPPENED SUDDENLY THERE WAS NO GRADUAL WARNING !

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!

TL* THE CONTACT OWNS A 2012 MAZDA CX-9. WHILE ATTEMPTING TO ACCELERATE FROM A TRAFFIC LIGHT, THE ACCELERATOR PEDAL WAS DEPRESSED; HOWEVER, THE VEHICLE FAILED TO RESPOND. THE CONTACT STATED THAT THERE WERE NO WARNING INDICATORS BEFORE OR AFTER THE FAILURE. THE BRAKE PEDAL ALSO BECAME EXTREMELY DIFFICULT TO DEPRESS. THE VEHICLE WAS TOWED TO CONTINENTAL MAZDA (LOCATED AT 2363 AURORA AVE, NAPERVILLE, IL 60540, (630) 352-5900) WHERE IT WAS DIAGNOSED THAT COOLANT ENTERED THE ENGINE OIL AND CAUSED THE ENGINE TO FAIL. THE CONTACT WAS INFORMED THAT THE ENGINE NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED AND PROVIDED CASE NUMBER: 1-2189354066. THE APPROXIMATE FAILURE MILEAGE WAS 52,000.

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.

BRAKES SLIP CAUSING UNEXPECTED INCREASE IN STOPPING DISTANCE EVEN AT LOW SPEED. VERY CONCERNED ABOUT FAMILY SAFETY. RESEARCH FOUND ISSUE WAS NOTED PREVIOUSLY AND SUPPOSEDLY CLOSED, BUT MANY COMPLAINTS LIKE MINE HAVE BEEN FILED SINCE. HOW MANY DEATHS MUST NHTSA SEE REPORTED UNTIL THEY TAKE ACTION AND RECALL THIS ADMITTEDLY FAULTY DESIGN?

VEHICLE STALLED WHILE EXITING THE HIGHWAY, ENGINE LIGHT ON, NOISE FROM TIMING CHAIN AREA, VEHICLE OVERHEATS, WATER PUMP FAILURE PUSHES ANTIFREEZE INTO THE OIL COMPARTMENT CAUSING THE ENGINE TO GET DAMAGED WITHIN MINUTES WHITEOUT A WARNING. THIS IS OBVIOUSLY A MAJOR VERY EXPENSIVE SAFETY ISSUE.
