2010 MAZDA CX-9 Complaints

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
