What 221 owners told NHTSA about the 2012 Mazda Cx-90 Phev

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.

I OWN A 2012 MAZDA CX9, WHICH I PURCHASED NEW. ON MONDAY MORNING (NOVEMBER 12, 2018) MY (CHECK ENGINE LIGHT CAME ON) AND SO I TOOK IT IMMEDIATELY TO THE DEALERSHIP FOR DIAGNOSIS. MY CAR WAS RUNNING BEAUTIFULLY, SO I JUST ASSUMED WITH THE WEATHER CHANGE, PERHAPS THE GAS CAP WASN'T TIGHTENED, AND THEY JUST NEEDED TO CLEAR THE CODES. IT TURNS OUT THE WATER PUMP FAILED AND APPARENTLY DESTROYED THE ENTIRE ENGINE. WHICH BECAME APPARENT AS I DROVE IT TO THE DEALERSHIP FOR DIAGNOSIS, PER THEIR RECOMMENDATION. MY CAR IS WELL MAINTAINED BASED ON THE DEALER RECOMMENDATIONS AND IS CONSISTENTLY SERVICED AT THE MAZDA DEALERSHIP. THE CAR IS IN FANTASTIC CONDITION WITH ONLY 90,000. AS AN OWNER, I DID EVERYTHING BY THE BOOK IN TERMS OF MAINTENANCE FOR MY CAR. I AM LETTING YOU KNOW, MAZDA HAS A SERIOUS PROBLEM AND IT'S A SAFETY ISSUE, AS WELL. IF A WATER PUMP CAN JUST FAIL WITHOUT WARNING AND COMPLETELY SHUT DOWN AN ENGINE, THAT'S NOT GOOD. I THINK THIS IS FAR MORE DANGEROUS THAN THE AIR BAG RECALL, WHICH IS ONLY A CONCERN IF YOU GET IN AN ACCIDENT. THERE IS NO WARNING ON THE WATER PUMP FAILING, AS IT'S SELF-CONTAINED WITHIN THE POWER TRAIN AND THE ONLY WAY TO CHECK THIS PART IS BY REMOVING THE ENTIRE ENGINE, WHICH LEADS ME TO BELIEVE THIS PART WAS NOT DESIGNED TO BE A WEAR PART. IT'S AN ENGINEERING DESIGN FLAW, THAT CAN CAUSE BODILY HARM IF IT FAILS, BECAUSE IT TAKES OUT THE ENTIRE ENGINE AND YOU LOSE CONTROL OVER THE VEHICLE.

WHILE DRIVING MY MAZDA CAR, IT SUDDENLY STARTED BUCKING AND CHECK ENGINE LIGHT CAME ON. CAR WAS TOWED TO THE DEALERSHIP. PER MAZDA MECHANIC, WATER PUMP MALFUNCTIONED FORCING COOLANT INTO THE ENGINE. FEEL THIS POSES A SIGNIFICANT SAFETY ISSUE AS THERE WAS VERY LITTLE WARNING POSING RISK OF ACCIDENT, ENGINE OVERHEATING AND POTENTIAL FIRE. THIS APPEARS TO BE A COMMON ISSUE AS MULTIPLE OTHER POSTS REPORTED

TAKATA RECALL" THIS IS IN RELATION TO CURTAIN AIRBAGS DEPLOYING WITHOUT WARNING OR IMPACT TO THE VEHICLE. THERE WAS NO ACCIDENT INVOLVED. TRAVELING DOWN THE FREEWAY AND THE CURTAIN AIRBAGS DEPLOYED.

THE TRANSMISSION WAS SHIFTING HARD BETWEEN 4TH AND 5TH GEAR. MY WIFE BROUGHT THE VEHICLE TO THE DEALERSHIP TO HAVE THE AIR BAG RECALL DONE. THEY THEN CHARGED US $122 TO UPDATE THE TRANSMISSION PROGRAM TO CORRECT THE FACTORY ISSUE. NOW IT SHIFTS FROM 6TH TO 3RD ON THE INTERSTATE.

I PUT MY VEHICLE IN THE MAZDA SHOP LAST YEAR 2017 FOR A RECALL AND I MENTIONED THAT THERE WAS SOMETHING I FELT IN MY BRAKES THEY TOLD ME THAT IT MAY BE DUST AND BY DRIVING IT WILL GO AWAY,MAZDA KNEW ABOUT THIS PROBLEM THEY SHOULD HAVE TAKEN CARE OF IT THEN.MY VEHICLE WAS TAKEN TO OURISMAN MAZDA DEALERSHIP ABOUT 2 WEEKS AGO AND I WAS TOLD THAT IT WAS MY BRAKE BOOSTER & MASTER CYLINDER LABOR IS $709.47 AND THE PARTS ARE $537.98 AND THE BRAKE FLUSH IS $202.61 TOTAL $1450.06 AND MY WARRANTY EXPIRED IN OCTOBER 2018. I THEN CALLED MAZDA AND I SPOKE TO A MS.JENNIFER A CUSTOMER EXPERIENCE REPRESENTATIVE AND SHE SAID SHE WOULD CHECK INTO IT.I THEN CALLED BACK TO OURISMAN MAZDA AND SPOKE TO MR.EMERSON AND HE TOLD ME THAT HE SPOKE TO MS JENNIFER AT MAZDA AND THAT MY OUT THE DOOR PRICE WOULD BE $553.16 AND THEY HAVE ALREADY ORDERED THE PART ,THEY STATED MAZDA CALLED OFF THE RECALL AND DID A 7 YEAR WARRANTY OR 90,000 MILES MY CAR IS NEITHER OF THEM FOR A 2012, THEN THEY WANTED TO SAY ITS BECAUSE WHEN MY CAR WAS PURCHASED? THEN TO TELL ME THAT WHEN I PUT MY CAR IN LAST YEAR FOR A RECALL IF IT WAS NOT MAKING A PROBLEM THEY WERE NOT GOING TO LOOK FOR ONE? ON THESE ROADS,MY CHILDREN,MY GRAND CHILDREN AND THE LIVES OF ALL PEOPLE I,AND I'M SURE A LOT OF PEOPLE FEEL .I HAVE BEEN SICK AND WITHOUT A LOANER CAR AND THIS IS UNEXCEPTABLE I WOULD GREATLY APPRECIATE YOUR HELP WITH THIS PROBLEM.MY CONTACT PERSON WITH OURISMAN MAZDA IS MR.EMERSON 240-863-2429 AND MY CONTACT INFO FOR MAZDA CUSTOMER REP IS JENNIFER 800-222-5500 PROMPT 2 THEN EXT 1133 (1-1930090754) THE RECALL NEEDS TO BE PUT BACK ON, I WAS NEVER NOTIFIED THAT THERE WAS A EXTENDED WARRANTY.THIS CAN RESULT IN SERIOUS INJURY OR DEATH,HOW DARE THEM PUT A PRICE ON THIS.

BRAKES WERE OCCASIONALLY 'TIGHT', HAD TO BE PUSHED VERY HARD TO GET THE VEHICLE TO STOP. WHEN I PUSHED THE BRAKES IT SOUNDED LIKE AIR WAS BEING PUSHED OUT. CHANGED PADS AND BRAKE FLUID, FLUSHED THE AIR OUT. ONLY MADE IT WORSE. NOW THE BRAKES ARE CONSTANTLY 'TIGHT' AND AFTER LEARNING THIS IS A COMMON ISSUE WITH THIS VEHICLE I'M GOING TO REPLACE THE BRAKE BOOSTER. RIDICULOUS THAT SO MANY ARE HAVING THIS ISSUE AND MAZDA ISN'T RECALLING THIS PART!

NHTSA ODI 11144752

VACUUM POWER BRAKE BOOSTER FAILURE, MY BRAKES DID NOT WORK AND MY CAR STALLED. THERE IS A WARRANTY EXTENSION FOR THIS PROBLEM - NOT A RECALL - I NEVER KNEW ANYTHING ABOUT IT. A CONSUMER MUST BE NOTIFIED OF A RECALL BUT NOT A WARRANTY EXTENSION BUT THIS IS A VERY DANGEROUS PROBLEM. I FEAR FOR THE SAFETY OF OTHERS WHO MAY NOT KNOW ABOUT THE PROBLEM. IF YOU DON'T KNOW ABOUT IT YOU DO NOT ASK TO HAVE IT CHECKED AND WHEN IT FAILS YOU ARE IN DANGER. I APPRECIATE THE WARRANTY EXTENSION BUT I HONESTLY THINK THAT I SHOULD HAVE BEEN NOTIFIED. NO ONE WAS INJURED AND THERE WAS NO PROPERTY DAMAGE - I BELIEVE THERE SHOULD BE SOME RECONSIDERATION REGARDING THE DECISION NOT TO ISSUE A RECALL ON THIS PROBLEM.

TL* THE CONTACT OWNS A 2012 MAZDA CX-9. WHILE DRIVING 35 MPH, THE BRAKE PEDAL WAS DEPRESSED, BUT FAILED TO ENGAGE. THE VEHICLE WAS EXAMINED BY AN INDEPENDENT MECHANIC WHO DIAGNOSED THAT THE POWER BRAKE BOOSTER NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 110,000.

NHTSA ODI 11112323

I PARKED MY MAZDA AFTER COMING BACK FROM MY LUNCH BREAK AND NOTICED THAT MY BRAKE PEDAL WAS A LOT HARDER TO PUSH. I ALSO HEARD A NOISE COMING FROM WHAT SEEMED LIKE THE PEDAL. IT SOUNDED LIKE I WAS LETTING AIR OUT OF A BALLOON. AFTER WORK, WHILE DRIVING IN REVERSE TO BACK OUT OF MY PARKING STALL, I NOTICED THE BRAKES WERE STILL VERY HARD TO PUSH. THE NOISE WAS ALSO STILL HAPPENING, BUT IT WAS LOUDER. I DECIDED NOT TO DRIVE MY VEHICLE UNTIL I HAD IT LOOKED AT BY A MECHANIC. WHEN MY MECHANIC STARTED MY VEHICLE AND BEGAN TO TEST DRIVE IT, THE NOISE WAS GONE, BUT HE ALSO FELT THAT IT WAS VERY HARD TO APPLY MY BRAKES. THE PROBLEM WAS DIAGNOSED AS A BAD BRAKE BOOSTER. AFTER THE PROBLEM WAS DIAGNOSED, I RESEARCHED COMMON COMPLAINTS WITH THIS, AND DISCOVERED THAT IT IS ALSO AN ISSUE IN THE EARLIER MODELS (2010 AND 2011) THIS IS A MAJOR SAFETY RISK THAT I WOULD LIKE INVESTIGATED. THANK YOU!

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

NHTSA ODI 11111568

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!

NHTSA ODI 11105359

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.

WHILE DRIVING MY VEHICLE ON THE HIGHWAY MY CAR WOULD NOT ACCELERATE WHEN I PRESSED ON THE GAS. MY RPM'S WENT UP TO 4 AND WOULD DROP DOWN WHEN I LET OFF THE GAS. WITHIN MINUTES MY STEERING WHEEL LOCKED UP AND THE CAR BASICALLY SHUT DOWN. I HAD TO TRY AND DRIFT TO THE SHOULDER IN HIGH SPEED TRAFFIC. WHEN I GOT TO THE SHOULDER THE CAR STARTED SMOKING. I HAD THE CAR TOWED TO MAZDA DEALERSHIP. THEY TOLD ME MY WATER PUMP WENT AND LEAKED FLUID THROUGHOUT THE ENGINE, RESULTING IN ME NEEDING A NEW $8,000 ENGINE. THEY TOLD ME THAT MAZDA DESIGNED THE CX9 WHERE THE WATER PUMP IS IN THE ENGINE BLOCK BEHIND THE TIMING BELT AND IT IS NOT SOMETHING THEY CAN EASILY INSPECT WHEN I BRING MY CAR IN FOR SERVICE. SO WHEN A WATER PUMP GOES ON THESE MAZDA CX-9'S IT RESULTS IN THE CONSUMER NEEDING A WHOLE NEW ENGINE. THEY ALSO STATED THAT THERE ARE NO INDICATORS THAT WILL NOTIFY YOU IF THERE IS A PROBLEM WITH THE WATER PUMP TO AVOID THIS FROM HAPPENING. THE SAFETY ISSUE IS THAT MY CAR WAS ON THE HIGHWAY AT THE TIME THIS OCCURRED WITH VEHICLES GOING AT HIGH SPEEDS. MY CAR BASICALLY SLOWED DOWN SIGNIFICANTLY AND EVENTUALLY STOPPED AND I COULD NOT TURN THE STEERING WHEEL TO BETTER ASSIST ME GETTING OUT OF THE WAY OF THE HIGH SPEED TRAFFIC.

NHTSA ODI 11062538

IF WATER PUMP FAILS THE ENGINE WILL SHUT DOWN WITHOUT WARNING OR ANY TYPE OF CHECK ENGINE LIGHT OR ALERT. COOLANT WILL FLOOD CRANKCASE IMMEDIATELY AND RUIN THE ENGINE . THIS OCCURRED WHILE DRIVING CREATING A SERIOUS SAFETY ISSUE POTENTIALLY CAUSING A COLLISION.
