2011 MAZDA CX-9 Complaints

BRAKE BOOSTER GOES OUT CAUSING BRAKES TO UNEXPECTEDLY MALFUNCTION AND NOT STOP THE CAR IN A TIMELY MANNER. BRAKES BECOME HARD TO PRESS, SOUND OF HISSING AIR FROM UNDER DASHBOARD, BRAKE PEDAL WAS PRESSED ALL THE WAY TO FLOOR AND STILL DID NOT STOP THE CAR IN A SAFE MANNER. NO WARNING LIGHTS ALERTED TO THIS PROBLEM PRIOR TO THIS INCIDENT. *TR

I JUST BOUGHT AN 2011 CX-9 MAZDA FEW WEEKS AGO. WHEN I WAS PARKING I NOTICED THAT EVERY TIME I PUT THE CAR IN DRIVE IT MAKE A SOUND VERY HARD, AND SOMETIMES WHEN PUTTING IT IN REVERSE. IT MAY BE SOME PROBLEMS WITH THE TRANSFER CASE. IN ADDITION, WHEN THE CAR IS RUNNING ON 2ND ANOTHER WEIRD SOUND. I AM TAKING THE CAR TO THE NEAR DEALER IF THE PROBLEM CONTINUE. *TR

TRAVELING WITH FAMILY ON I95 STARTED SMELLING A BURNING ODOR. LATER DEVELOPED A DISTINCT VIBRATION AND GRINDING SOUND. GOT IT HOME NOW NON USABLE. VEHICLE WAS PREVIOUSLY REPAIRED AT MY SHOP , A LOSS DUE TO HURRICANE SANDY, AND AS SUCH BRANDED. FAULKNER MAZDA AND MAZDA CORPORATION BOTH DENIED ANY WARRANTY CLAIM DUE TO TITLE BRANDING EVEN THOUGH BOTH ADMITTED IT WAS A SAFETY ISSUE , ALTHOUGH THE SERVICE DEPT AT FAULKNER DID ADD "THAT ANYTHING COULD CAUSE AN ACCIDENT". I AM JUST LUCKY THAT IT DIDN'T GRENADE WHILE ON THE INTERSTATE AT SPEED WITH MY FAMILY IN THE CAR. CORPORATE MAZDA ADVISED ME TO SAVE MY RECEIPTS IN CASE THEY ISSUE A RECALL IN THE FUTURE. WILL NOT RECOMMEND MAZDA TO ANYONE IN THE FUTURE. *TR

THE MAZDA 2011 CX-9 CROSSOVER SUV SEEMS TO HAVE A DEFECT IN THE POWER TRANSFER UNIT (PTU). MAZDA NORTH AMERICAN OPERATIONS ISSUED A LETTER TO MAZDA OWNERS INFORMING ABOUT A SPECIAL SERVICE PROGRAM TO EXTEND THE WARRANTY COVERAGE FOR THE REPAIR OF THE POWER TRANSFER UNIT (PTU) ON "CERTAIN 2010-2011 CX-9 ALL-WHEEL DRIVE VEHICLES PRODUCED FROM JULY 28, 2009 THROUGH DECEMBER 2, 2013." I QUOTE THE LETTER. ON MARCH 18, 2015, I BEGAN TO EXPERIENCE A PROBLEM WHEREBY MY 2011 CX-9 MADE A GRINDING AND SNAPPING SOUND WHEN IN REVERSE MODE. THIS BEHAVIOR WAS FOLLOWED BY A PUNGENT ODOR IN THE CABIN. I CONTACTED THE NEAREST DEALERSHIP AND TRIED TO GET AN IMMEDIATE APPOINTMENT TO EXAMINE THE VEHICLE. HOWEVER THE DEALERSHIP COULD NOT ACCOMMODATE ME NOR EXPRESSED ANY AWARENESS OF THE SYMPTOMS. YET, THE LETTER WAS PUBLISHED SINCE LAST YEAR. I CONTACTED A LOCAL MECHANIC AND HAD THEM INSPECT THE VEHICLE AND THEY DIAGNOSED THE PROBLEM EXACTLY AS DESCRIBED IN THE LETTER FROM MAZDA. IN FACT, THE MECHANIC IS AWARE OF THIS PROBLEM WITH MAZDA AND LINCOLN BRAND VEHICLES. CURRENTLY, I AM HAVING TROUBLE GETTING IMMEDIATE ASSISTANCE FROM THE DEALERSHIP OR MAZDA NORTH AMERICAN OPERATIONS. I CALLED SEVERAL TIMES TO THE DEALERSHIP AND THEY WERE UNRESPONSIVE. IS NHTSA AWARE OF THIS PTU DEFECT AND WHAT WAS NECESSARY TO REQUIRE A RECALL/REPLACEMENT OF THE PTU 'PRIOR' TO INEVITABLE FAILURE AS WE EXPERIENCED? THANK YOU. *TR

I HAVE A 2011 MAZDA CX-9 AND WHEN SLOWING DOWN THERE IS A JOLT WHEN IT SHIFTS FROM 4TH TO 3RD. THIS SEEMS TO HAPPEN MORE WHEN ITS COLD OUT. IT ONLY HAPPENS WHEN IT SHIFTS FROM 4TH TO 3RD. ITS NOT ALL THE TIME ITS JUST RANDOM. *TR

I NOTICED A HISSING NOISE WHEN I PRESS THE BRAKE PEDAL. IT GOES AWAY WHEN I LET OFF THE BRAKE. I HAVEN'T NOTICED A DIFFERENCE IN THE BRAKE PEDAL BUT I WILL BE PAYING CLOSE ATTENTION TO IT. THIS IS A MAJOR SAFETY ISSUE AND SHOULD BE RECALLED ASAP. I HAVE 2 KIDS THAT RIDE IN THIS CAR. I CALLED THE DEALERSHIP AND HAVE AN APPOINTMENT TOMORROW. THE SERVICE DEPARTMENT SAID THEY HEARD ABOUT THIS ISSUE BUT HAVEN'T HAD A REPAIR LIKE THIS YET. I WILL UPDATE WHAT I FIND OUT. *TR

THIS IS THE SECOND HAPPENED TO MY MAZDA CX9, 2011. THE BRAKE STARTED TO HAVE HISSING SOUNDS WHILE STEPPING ON BRAKE. THE BRAKE PEDAL IS HARDER THAN USUAL TO DEPRESS. THE BRAKE FUNCTIONS HAS BEEN REDUCED AROUND 30~50% LESS THAN NORMAL. THIS HAS PUT DERIVING SAFETY IN JEOPARDIZED. THIS IS THE SECOND TIME MY CX9'S BRAKE BOOSTER FAILURE. THE FIRST TIME IS IN YEAR 2012. I WORKED WITH MAZDA TO HAVE BRAKE BOOSTER REPLACED. HOWEVER, DEALER SEEMED NOT REALIZED THERE IS A WARRANTY EXTENDED PROGRAM FROM MAZDA --- MAZDA SPECIAL SERVICE PROGRAM -93 (SSP93). THIS IS OFFICIAL RECORDED IN NHTSA ACTION NUMBER PE14005. DEALER TRIED CONTACTING MAZDA FOR THIS PROGRAM. BUT MAZDA KEPT NOT RESPONDING, IT HAS BEEN TWO WEEKS BUT STILL NOT MESSAGE BACK FROM THEM. I PAID THE REPAIRMEN OF THE DEFECTIVE BRAKE BOOSTER (PARTS & LABOR) FROM MY OWN PACKET AT THIS POINT. DESPITE THE DEFECTIVE PARTS FOR JEOPARDIZING DRIVING SAFETY, MY COMPLAINTS TO MAZDA IS ALSO FOR THEIR NON-RESPONSIVE TO CUSTOMER'S WARRANTY PROGRAM WHICH THEY HAVE MADE.

I ACTUALLY NOTICED WHEN I STARTED MY VEHICLE UP AND PRESSED ON THE BRAKE PEDAL, IT SEEMED TO SLOWLY SINK ALL THE WAY TO THE FLOOR AND MADE A HISSING NOISE. THE NOISE ONLY STOPPED WHEN I TOOK MY FOOT OFF THE BRAKE PEDAL. AS I WAS DRIVING, ON SEVERAL OCCASIONS I HAD DRAMATICALLY REDUCED STOPPING PERFORMANCE WHEN APPLYING THE BRAKE. I'VE GONE THROUGH SEVERAL STOP SIGNS AND HAVE ALMOST REAR ENDED OTHER VEHICLES. THIS SEEMS TO HAVE SUDDENLY HAPPENED, I FIRST NOTICED IT ON 3/1/15. THIS WASN'T HAPPENING ON OR BEFORE 2/26/15. I SUSPECT THE POWER BOOSTER OR MASTER CYLINDER HAVE FAILED, THOUGH I'M CONCERNED THAT THIS HAPPENED WITH ONLY 61,000 MILES ON IT. *TR
