2012 MAZDA CX-9 Complaints

LETTER FROM SENATOR GARDNER ON BEHALF OF CONSTITUENT REGARDING HIS CONCERNS ABOUT A DEFECTIVE BRAKE DESIGN SYSTEM WHICH EXISTS IN THE MAZDA CX-9. *LD *JS

VIRTUALLY COMPLETE LOSS OF BRAKING. QUICK ONSET. APPARENTLY THE SAME UNDERLYING DEFECT AS INVESTIGATED IN 2008-2011 (INCORRECTLY CLOSED) AND IN TSB #SSP93 NHTSA ID #10117767. THE DEALER HAD THE CAR IN FOR ANOTHER ISSUE (RECALL) IN MARCH; BUT DID NOT FIX THIS ISSUE (NOT ALLOWED TO SPEAK OF IT -- UNLESS THE CUSTOMER BRINGS IT UP (PERSONAL COMMUNICATION 7/3/2018). NHTSA STAFF SHOULD HAVE NOTICED THAT THE 2012 TSB IS ESSENTIALLY A CONTINUATION OF THE CORE ISSUE FROM 2008 ONWARD. A FAILING BOOSTER SHOULD INCREASE THE EFFORT TO BRAKE, IT SHOULD NOT BE PERMITTED TO RESULT IN COMPLETE LOSS OF FUNCTIONALITY!

AT JUST OVER 90,000 MILES I HAD TRANSFER CASE PROBLEM THAT EVERYONE IS POSTING. AS DESCRIBED BY MECHANIC IT IS A MANUFACTURING DEFECT. TRANSFER CASE IS PLACED JUST ABOVE CATALYTIC CONVERTER (WHICH THROWS OFF ALOT OF HEAT) AS A RESULT OIL IN TRANSFER CASE COOKS OVER TIME AND GEARS ARE DESTROYED. MAZDA DID NOT PROVIDE A WAY TO REPLACE AND OR CHECK THIS FLUID WITHOUT TAKING DOWN THE ENTIRE TRANSMISSION. MECHANIC SAID I WILL HAVE THIS PROBLEM AGAIN AT ROUGHLY ANOTHER 80-100,000 MILES. YEAR AND A HALF LATER I NOTICED A VERY SOFT BRAKE. I REPLACED BRAKE PADS AND DRUMS, AND BRAKE FLUID. I HAVE A VERY HARD BRAKE WHICH THEN SPORATICALLY GOES SOFT. AGAIN I LOOKED UP THIS ISSUE AND FOUND AGAIN MAZDA IS AWARE OF THIS ISSUE AND EXTENTED WARRANTY TO 90,000 MILES. AGAIN I'M JUST OVER THE WARRANTY ALLOWANCE AND NOW MY BRAKE POWER BOOSTER AND POSSIBLY MASTER CYLINDER NEED TO BE REPLACED. BOTH ARE KNOWN ISSUES BY MAZDA. UNFORTUNATELY I WAS THE LUCKY ONE WHO WAS THE BENEFICIARY OF BOTH PROBLEMS JUST OVER THE 90,000 MILE WARRANTY. I REACHED OUT TO MAZDA TO REQUEST SOME ASSISTANCE WITH AT LEAST THE COST OF THE PARTS ON THE BRAKE POWER BOOSTER. I WAS GIVEN A QUICK NO BY MAZDA. VERY FRUSTRATING SINCE THESE ARE BOTH KNOWN PROBLEMS AND THEY WILL NOT AT LEAST WORK WITH ME ON THE PARTS COST.

I WAS DRIVING TO GET LUNCH FROM WORK AND WENT TO STOP AT AT TRAFFIC LIGHT ON A VERY BUSY ROAD AND MY VEHICLE WOULDN'T STOP. THE PEDAL WAS HARD AND I HAD TO PUSH IT ALL THE WAY DOWN AND NARROWLY MISSED THE VEHICLE IN FRONT OF ME. I DROVE CAREFULLY BACK TO WORK AND HAD THE VEHICLE TOWED TO THE SHOP. IT WAS THE BRAKE BOOSTER. I THEN DID SOME RESEARCH ON THE SUBJECT SINCE MY VEHICLE IS STILL FAIRLY NEW AND IT SEEMED ODD. I SAW SO MANY COMPLAINTS AND IT SCARED ME. THIS NEEDS TO BE RECALLED BEFORE SOMEONE GETS SERIOUSLY HURT!!

AWD TRANSFER CASE UNIT FAILURE THE TRANSFER CASE OF MY 2012 MAZDA CX-9 FAILED WHILE DRIVING ON THE HIGHWAY AT CRUSISING SPEED CREATING A DANGEROUS SITUATION. THE FIRST SIGN OF FAILURE WAS A HEAVY BURNED OIL ODOR. THE ODOR WAS CAUSED BY A LOT OF OIL POURING OVER THE EXHAUST PIPE WHICH ALSO WAS A DANGER OF FIRE. AFTER INSPECTION MECHANIC FOUND THAT THE TRANSFER CASE HAD A LEAK AND THE COUPLING SPLINES BETWEEN THE TRANSMISSION AND THE POWER TRANSFER CASE AND THE RIGHT DRIVESHAFT WERE EXTREMELY CORRODED, THIS CORROSION WAS NOS EVIDENT FROM OUTSIDE BECAUSE EITHER THE TRANSMISSION AND THE TRANSFER CASE ARE MADE OF ALUMINUM AND THE DRIVESHAFT IS INSERTED THROUGH THE POWER TRANSFER UNIT INTO THE TRANSMISSION, BUT FOR UNKNOWN REASONS, THE TRANSMISSION OUTPUT AND TRANSFER CASE INPUT PARTS WHICH ARE MADE OF STEEL ARE BADLY CORRODED AND GOT SEVERELY WORN WITH A LOT OF RUST ACCUMULATION IN PLACE, WHICH IN TIME WILL CAUSE A TRACTION LOSE THAT WOULD SEVERELY COMPROMISE DRIVING SAFETY. MAZDA ISSUED A BULLETIN TO ADDRESS THE POWER TRANSFER CASE UNIT BUT IS LIMITED TO 7 YEARS OR 90000 MILES WHICH IS A LOW MILEAGE FOR A PROBLEM LIKE THIS TO DEVELOP AND WHEN THE OWNER TRIES TO TAKE ACTION MAZDA WILL NOT COVER THE REPAIRS. I THINK THI IS A MANUFACTURING QUALITY CONTROL ISSUE SINCE ITS COMPLETELY BEYOND THE ACTIONS OR FAILURE OF THE OWNER TO FOLLOW A PROPER MAINTENTANCE SCHEDULE SINCE THE OWNERS MANUAL DOESNT SAY ANYTHING ABOUT IT. HTTPS://STATIC.NHTSA.GOV/ODI/TSBS/2014/CSC-10055535-7382.PDF MAZDA DOES NOT HAVE A SERVICE SCHEDULE FOR THIS PART AND IS CONSIDERED TO BE MANTENTANCE FREE HOWEVER, IF THE ISSUED THE SERVICE BULLETIN IS BECAUSE THEY KNOW THIS PART HAS POTENTIAL ISSUES. THE INVOLVED PARTS SHOULD BE REPAIRED BY MAZDA SINCE IS A DESIGN OR MANUFACTURE PROBLEM. THANK YOU FOR YOUR ATTENTION TO THIS MATTER.

THE TRANSFER CASE IS LEAKING AND GOING TO GO COMPLETELY OUT ON MY 2012 MAZDA CX-9, I NOTICED THE SAME GEAR SHIFTING PROBLEM IN MY 2004 MAZDA 6 WAGON. THE CAR FEELS LIKE DRIVING A STICK, IT JOLTS WHEN SHIFTING TO DRIVE AND WHILE MOVING IT FEELS LIKE IT IS SHIFTING EARLY. THIS IS A KNOWN PROBLEM WITH MAZDA BUT A RECALL IS YET TO SURFACE FOR THIS ISSUE.

APPLY WITH THE BRAKE PEDDLE IS PRESSED. CAN WILL CONTINUE ROLL, AND IN SOME CASES, BECOME VERY HARD TO STOP. SO FAR, NOT HIT ANYTHING, BUT HAVE HAD ISSUES ON NOT BEING ABLE TO STOP AT STOP LINES EVEN AT SLOW SPEEDS.

I JUST HAD ONLY 33K MILES ON MY 2012 MAZDA CX-9, THE TRANSFER CASE BROKEN FROM INSIDE YESTERDAY MORNING (FRIDAY APRIL 6TH 2018) WHEN I COMMUTE FROM HOME TO WORK. I WAS DRIVING ON A NEIGHBORHOOD ROAD GO STRAIGHT. FIRST THE LOUD NOISE RAISE FROM UNDER HOOD THEN THE SUV LOST POWER. LUCKILY I HAVE ROOM TO PULL OVER AND PARK IT AT SIDE OF THE ROAD. IT DID PUT ME AND PUBLIC IN DANGER BY THE FAULTY TRANSFER CASE. I HAVE TO CALL A TOW TRUCK TO GET MY SUV TO AUTO SHOP. SERVICEMAN CALLED ME THIS MORNING AND TOLD ME THAT I NEED TO REPLACE THE BAD TRANSFER CASE.

THE BRAKING SYSTEM DID NOT FUNCTION CORRECTLY RESULTING IN A CRASH. BRAKES WERE HARD AND COULD NOT BE DEPRESSED WHEN A VEHICLE STOPPED QUICKLY IN FRONT OF ME. TOOK THE CAR TO MAZDA DEALERSHIP AND THEY INFORMED ME THAT THIS IS A KNOWN PROBLEM AND REPLACED THE BRAKE BOOSTER UNDER A "SPECIAL WARRANTY". THIS NEEDS TO BE A SAFETY RECALL, I WAS NEVER NOTIFIED OF THIS SAFETY ISSUE. IT IS IMPERATIVE THAT NHTSB REOPEN THE INVESTIGATION ON THIS PROBLEM AS IT DOES NOT ONLY INVOLVE 2010 AND 2011 CARS AND DOES NOT ONLY OCCUR IN "HIGH AMBIENT TEMPERATURES". VEHICLE WAS IN MOTION AND WAS SLOWING ON AN SLIGHT UPHILL GRADE. VEHICLE IS 5 YEARS OLD AND HAS 53,000 MILES.

I WAS GOING 10MPH TO STOP IN FRONT OF MY DAUGHTER'S SCHOOL TO PICK HER UP WHEN MY BRAKES WERE DIFFICULT TO APPLY. I HAD TO USE BOTH OF MY FEET TO STOP MY CAR FROM CRASHING INTO THE CAR IN FRONT OF ME. I HEARD A HISSING SOUND WHEN I APPLIED MY BRAKE. THE LIGHTS ON MY DASH ABS LIT UP AND THEN MY CAR SHUT OFF. I WAS SCARED AND DIDN'T KNOW WHAT HAPPENED. I WAITED A FEW MINUTES WHEN NO ONE WAS IN FRONT OF ME AND TRIED TO DRIVE AWAY AND IT HAPPENED AGAIN. I LEFT MY CAR AT A GAS STATION FOR A TOW TRUCK TO GET IT. I WAITED FOR THE CAR TO BE TOWED AND GOOGLED WHAT HAPPENED. TURNS OUT OVER 50 OTHER PEOPLE HAVE HAD THE SAME ISSUE HAPPEN WITH THE SAME CAR AND YEAR. THE BRAKE BOOSTER ASSEMBLY WENT OUT BETWEEN 43000-50000 MILES. SOME SCENARIOS WERE WORSE THAN MINE. THEY WERE DRIVING FASTER THAN 10 MPH AND COULD NOT STOP THE CAR IN TIME OR AT ALL. THERE IS NO RECALL AND THE DEALERSHIP SAID BECAUSE I MOVED TO GUAM FROM WASHINGTON I HAD TO PAY OUT OF POCKET FOR THE REPAIR. I HAD IT REPLACED AND IN DECEMBER AND STILL HAVE NOT BEEN ABLE TO DRIVE IT. THE PART THEY REPLACED IS FAULTY TOO. AND THEY ORDERED A NEW PART. SO ITS SITTING TILL THE PART ARRIVES ON THE ISLAND OF GUAM. THIS SITE I WAS ON HAS LOTS OF PEOPLE WITH SIMILAR ISSUES WITH THE BRAKES. PLEASE LOOK INTO THIS. THE BRAKES ARE A BIG ISSUE IN A CAR.
