The water pump failed and leaked coolant into the engine, causing motor damage which requires motor replacement. There was no evidence of any failure until the vehicle overheated while being driven. This is a known design flaw of the engine design but no recall has been issued.

I had engine failure with a complete loss of power and a shuttering of the steering wheel while pulling into a parking lot and going less than 30 miles per hour. The temperature gauze went from cold to hot suddenly. There were no leaks of coolant or oil and no signs that the engine was out of water or that the water pump had "melted". On the final car repair trip we found out that the engine has an internal water pump that failed and resulted in oil & water getting into the engine. The engine light NEVER came on, I had complained about the tire pressure light blinking on and off in November 2021 and the deceleration issue I was having. The dealer did a coolant flush 11/2021. In early March 2022 the engine shut off as I was backing out of the driveway. I took it to a repair shop nearby they could not find anything wrong except that the car went into limp mode. They also did a coolant flush and radiator cap exchange since I forgot I had just done one on Nov. Less that a week later the engine failed again. We towed the car to the dealer for the third trip in less than four months. I am really disappointed that Mazda failed to recall the engine. I could have been seriously hurt if I had been traveling at high speeds. The CX9 had less than 135,000 miles at 12 years old.

Our 2010 Mazda CX-9 stopped on the highway and had to be towed away. The dealer determined it was an engine failure due to a faulty water pump. It had leaked into the engine, causing permanent damage. No warning lights. The car just stopped. Two dealerships did not want to repair. There is a class action lawsuit. https://www.ktmc.com/mazda-water-pump-engine-failure There should be a recall. We need a refund for the repair we had done, totaling more than $7000. Please look into this safety issue. Mazda Corporate has our complaint on file. We are expecting a refund.

My vehicle completely shut off while idling in park with no prior warning to anything being wrong. Put coolant in since the container was empty. Replaced thermostat, but vehicle was still overheating. Had it towed to Flow Mazda of Fayetteville and had them run a diagnostic. They determined that coolant was leaking into the oil due to a broken water pump. It was estimated to cost approximately $5,000 to repair with no guarantee that it would fix the problem. They pulled 4 sludge codes. There is currently a lawsuit against Mazda for this specific problem that was filed in 2019.

WE WERE SITTING IN A PARKING LOT WAITING ON A PIZZA. WE NOTICED THE A/C WASN'T COOLING, AND THEN NOTICED THE CAR WAS STARTING TO OVERHEAT. (THIS WAS THE FIRST TIME EVER). WE CHECKED THE RADIATOR, IT WAS EMPTY. WE PURCHASED COOLANT AND FILLED UP THE RESERVOIR. NEVER SAW ANY LEAKS. CAR STARTED BUT SEEMED SLUGGISH LIKE THE BATTERY WAS LOW. WE GOT OUR PIZZA AND DROVE ABOUT 6 MILES WHERE WE PARKED TILL WE TOOK IT TO THE DEALER ON MONDAY. OUR MECHANIC CALLED ME LATER TO TELL ME THAT THE WATER PUMP HAD FAILED AND THAT IT HAD LEAKED INTO THE OIL PAN AND WE WOULD HAVE TO HAVE THE ENGINE REPLACED. THE REPAIR TOTAL FOR MY CX9 IS AT $9K. WE HAVE 108,000 MILES ON THE VEHICLE. MY VEHICLE IS STILL SITTING AT THE DEALER.

WHILE DRIVING ON A CITY STREET, AND WITHOUT ANY INDICATION THAT SOMETHING WAS WRONG, ALL OF A SUDDEN THREE WARNING LIGHTS CAME ON, ENGINE LOST POWER, ACCELERATOR, BRAKES AND STEERING WERE UNRESPONSIVE. I AM LUCKY I COULD MANAGE TO GET INTO A TURN LANE AND STOP USING THE EMERGENCY BRAKE. CAR WAS TOWED TO MAZDA. TOLD WATER PUMP FAILED AND NOW COOLANT IS MIXED WITH ENGINE OIL, ENGINE LIKELY RUINED. THE CAR HAS 66,000 MILES ON IT. INTERNET RESEARCH SHOWS THIS IS A KNOWN PROBLEM ON CX-9S AND MAZDA DID NOT ISSUE RECALL. IS IT SAFE FOR THESE CARS TO BE ON THE ROADS?

ME AND MY HUSBAND WERE ON OUR WAY HOME FROM WORK. THE CAR SUDDENLY OVERHEATED AND WE LOST POWER ON I-35, WE WERE ABLE TO GET THE CAR TO AN EXIT AND WAS NEARLY HIT BY ANOTHER CAR DUE TO LOSS OF STEERING AND POWER. WE HAD THE CAR TOWED TO A MAZDA DEALERSHIP. THERE IS ENGINE COOLANT IN THE OIL AND WE ARE TOLD IT NEEDS A NEW MOTOR.

THE ENGINE OVERHEATED WHILE DRIVING ON A HIGHWAY AT HIGH SPEED AND FAILED WITHOUT WARNING. AFTER INVESTIGATION IT WAS FOUND THAT WATER PUMP MALFUNCTIONED FORCING COOLANT INTO THE ENGINE. IT IS NOW COMPLETELY INOPERABLE AND THE CAR HAS ONLY AROUND 80,000 MILES ON IT. THIS IS A MAJOR SAFETY ISSUE! THE CAR WAS SERVICED AND OIL CHANGED JUST A FEW MONTHS BEFORE THIS HAPPENED. THIS IS A MAJOR DESIGN FLAW ON MAZDA'S PART, WHICH THEY SEEM TO KNOW ABOUT AND NEVER ISSUED A RECALL TO GET ALL THE CARS FIXED. REPLACING AN ENGINE IS NOT SOMETHING MOST FAMILIES HAVE THE BUDGET FOR OR EVEN THINK ABOUT WHEN THE CAR IS LESS THAN 10 YEARS OLD. THERE WERE NO WARNING SIGNS OF WATER PUMP FAILURE. MAZDA NEEDS TO WARN CX-9 OWNERS WITH TSB OR RECALL THE WATER PUMP. THE WATER PUMP IS NOT BURIED INSIDE THE ENGINE AND CANNOT BE VISUALLY INSPECTED. HAVING A VEHICLE SHUT OFF ABRUPTLY WHEN TRAVELING AT HIGH SPEEDS IS A SERIOUS RISK FOR BOTH DRIVER, VEHICLE OCCUPANTS AND SURROUNDING MOTORISTS. I HOPE NHTSA TAKES THIS COMPLAINT SERIOUSLY AND TAKES ACTION BEFORE A SERIOUS OR FATAL INJURY OCCURS.

ON JAN 12, 2019 WE WERE DRIVING HOME AND WITHOUT WARNING THE TEMPERATURE GAUGE SPIKED AND THE CHECK ENGINE LIGHT CAME ON. THE ENGINE STOPPED AND I WAS ABLE TO GET THE VEHICLE OFF THE ROAD. I LOOKED TO SEE THE COOLANT RESERVOIR WAS EMPTY. I WAS ABLE TO REFILL IT, THINKING POSSIBLY THERE WAS A LEAK. IT GOT US HOME SAFELY. THE NEXT DAY, ENROUTE TO THE RADIATOR SHOP; THE SAME THING HAPPENED. AFTER A TOW HOME, THEN A TOW TO THE RADIATOR SHOP AND EVENTUALLY A TOW HOME, IT WAS DIAGNOSED AS A WATER PUMP FAILURE AND NOW A NEW ENGINE IS THE ANSWER FOR THE REPAIR. THERE WAS ABSOLUTLY NO WARNING TO THIS HAPPENING AND THE WATER PUMP IS INTERNAL. I UNDERSTAND THAT THE PUMP CAN/WILL WEAR OUT. I GET IT. WHERE IT'S LOCATED IS A JOKE AND I'VE READ IT'S AT LEAST A $1500 - $2000 FIX, JUST FOR THE PUMP REPLACEMENT. THE MAIN ISSUE IS THE NO WARNING WHATSOEVER!

CAR WAS ALWAYS SERVICED REGULARLY. ONE DAY I WAS ABOUT TO GET ON A BUSY HIGHWAY INTO BOSTON JUST BEFORE RUSH HOUR, WHEN MY CAR SUDDENLY MADE A LOUD KNOCKING NOISE IN THE ENGINE. I IMMEDIATELY PULLED OVER AND THEN THE CAR SHUT OFF. NO LIGHTS EVER CAME ON BEFOREHAND AND NO LEAKING OF FLUIDS EVER HAPPENED BEFORE INCIDENT. HAD IT TOWED TO MAZDA DEALER, WHO AT FIRST TOLD ME THEY WOULDN'T BE ABLE TO EVEN LOOK AT IT FOR 6 DAYS. FRIEND WORKED THERE AND GOT MECHANICS TO LOOK AT IT RIGHT AWAY. THEY SAID THE WATER PUMP WAS GONE AND IT WOULD COST $3500 TO FIX IT. THE WORST PART OF IT WAS, THAT ACCORDING TO THE DEALERSHIP, THEY KNOW THAT THERE IS A FLAW WITH WHERE THE WATER PUMP IS LOCATED IN THE ENGINE, AND THAT BECAUSE OF THIS THE ENGINE WAS MOST LIKELY GONE AS WELL. IN THEIR WORDS, THEY HAVE REPLACED MANY WATER PUMPS IN THESE SAME SITUATIONS OVER THE YEARS, AND ONLY ONE CAR DIDN'T NEED A NEW ENGINE. THEY RECOMMENDED FIXING THE WATER PUMP, THEN PUTTING IN A NEW ENGINE--$10,000 WORTH OF WORK. WE BOUGHT THIS CAR CERTIFIED PRE-OWNED FROM A DEALERSHIP. IT ONLY HAD 108,000 MILES ON IT AND THE EXTENDED WARRANTY HAD JUST ENDED 8 MONTHS BEFORE. I HAVE NUMEROUS OTHER CARS IN MY LIFETIME AND NEVER HAVE I HAD TO REPLACE AN ENTIRE ENGINE, JUST BECAUSE THE WATER PUMP WAS GONE! THIS CAR SHOULD HAVE BEEN WORTH ABOUT $9K-$11K FOR RESALE, AND INSTEAD MAZDA WANTED TO GIVE US $2K TOWARDS A DOWN PAYMENT FOR LEASING ANOTHER OF THEIR CARS. THEY GAVE US A RATE THAT THEY CLAIMED WAS A SPECIAL ONE, HOWEVER, I FOUND OUT I COULD GET AN EVEN BETTER ONE ONLINE MYSELF! WHEN WE CALLED THEM ON THIS AND SAID WE WERE TIRED OF DEALING WITH THIS, THEY TOLD US THEY WOULDN'T TALK WITH US ANYMORE. VERY DISAPPOINTING TO A FAMILY THAT CAREFULLY WATCHES ITS MONEY AND BUDGETS FOR EMERGENCIES, BUT WEREN'T PREPARED TO NEED AN ENTIRELY NEW CAR BEFORE THE OTHER WAS EVEN PAID FOR! SO UNFAIR!

WHILE TRAVELING 65MPH ON HIGHWAY WITH FAMILY THE VEHICLE SHUT DOWN, ENGINE LIGHT APPEARED AND WE NEARLY WERE STRUCK BY ANOTHER VEHICLE WHEN PULLING OVER. CX-9 WAS TOWED 75 MILES TO MECHANIC WHO INFORMED US COOLANT ENTERED THE ENGINE FROM FAILED WATER PUMP AND ENGINE NEEDS REPLACEMENT ($4000). MAZDA SERVICE MANAGER CONFIRMED THIS IS NOT UNCOMMON AND CONFIRMED ENGINE WILL NEED TO BE REPLACED. WHEN RESEARCHING CX-9 WATER PUMP FAILURE ONLINE I FOUND MANY DISTURBING TESTIMONIALS OF OTHER CX-9 OWNERS WITH SIMILAR EXPERIENCES. THERE WERE NO WARNING SIGNS OF WATER PUMP FAILURE. MAZDA NEEDS TO WARN CX-9 OWNERS WITH TSB OR RECALL THE WATER PUMP. THE WATER PUMP IS NOT BURIED INSIDE THE ENGINE AND CANNOT BE VISUALLY INSPECTED.

I WAS DRIVING MY CAR WHEN THE TRANSFER CASE ON MY 2010 CX9 BROKE AT 109.000 MILES AND SPLINE GEAR IS WORN OUT. OVERWHELMING OIL SMELL COMING BACK INTO CAR ALONG WITH HORRIBLE GRINDING NOISE. TOOK TO MY MAZDA DEALER, MAZDA WASN'T SURE IF THEY COULD FIX, SUGGESTED REPLACING TRANSMISSION. MAZDA TRIED TO FIX THE TRANSFER CASE ISSUE, BUT COULD HAVE HUMMING NOISE. INSTEAD OF HUMMING NOISE, AFTER ONE DAY OF RECEIVING MY CAR BACK, TRANSMISSION IS FAILING. ALREADY PUT $2200 INTO THIS REPAIR, BUT WAS TOLD THE TRANSMISSION COULD FAIL AT ANY TIME. I FIND THIS HARD TO BELIEVE AFTER I PUT MY CAR IN FOR SCHEDULED MAINTENANCE ALL THE TIME AND TAKE GREAT CARE OF MY CAR.

TAKATA RECALL I HAVE A MAZDA CX9 2010, I GOT NO INDICATION THAT THERE WAS A PROBLEM WITH MY WATER PUMP. THE CARE DID NOT OVER HEAT, IT DID NOT STALL AND I WAS NO STEAM COMING FROM THE CAR. I DROVE MY VEHICLE TO THE OTHER SIDE OF THE WATER MORE THAN 20 MILES FROM MY HOME, SO THAT I COULD GO TO WORK. IF IT WERE NOT FOR THE PHARMACIST AT MY JOB I WOULD HAVE GOTTEN IN MY CAR AND DROVE OFF. HE NOTICE A PUDDLE UNDER MY CAR AND ASKED ME TO COME OUTSIDE SO HE COULD INVESTIGATE THE SITUATION FURTHER. HE SAW WHERE THE FLUID WAS COMING FROM AND WENT UNDER THE CAR TO TOUCH THE FLUID AND FOUND THAT IT WAS MY ANTI-FREEZE. IF I KNEW I HAD A PROBLEM I WOULD HAVE NEVER DRIVEN THE CAR THAT FAR FROM HOME. I GOT A QUOTE FROM THE DEALER THAT IT WOULD COST ME $2050 TO REPAIR THE WATER PUMP. AS I DID RESEARCH, I FOUND THAT THIS IS SOMETHING THAT GOES ON WITH THESE VEHICLES AND THERE IS NO REAL WAY AROUND HAVING TO PAY THE DEALER THAT TYPE OF MONEY TO REPAIR THE PROBLEM BECAUSE OF THE WAY THE PUMP IS PLACED INSIDE OF THE ENGINE CAVITY. AT THIS POINT I DO NOT KNOW WHAT TO DO BECAUSE I DO NOT HAVE THE MONEY FOR THIS TYPE OF REPAIR ON A VEHICLE THAT WAS DESIGNED TO SCREW ME OVER. I WISH I DID MY RESEARCH BEFORE BUYING THIS VEHICLE. IF I HAD THE CHANCE TO DO IT ALL OVER AGAIN I WOULD NOT PICK A VEHICLE THAT REQUIRES ONLY THE DEALER TO REPAIR IT. I THINK THAT THIS IS UNFAIR FOR ANY CONSUMER TO HAVE TO PAY THAT AMOUNT OF MONEY BECAUSE OF THE DAMAGE THE WATER PUMP HAS DONE TO THE ENGINE BECAUSE OF ITS PLACEMENT. I AM SO UPSET AND NOT HAPPY ABOUT HOW MY FIRST CAR (THAT I LOVE) EXPERIENCE HAS TURNED OUT. I THANK GOD THAT I WAS NOT ON THE HIGHWAY. I COULD HAVE DIED THAT DAY.

AFTER RECENTLY RECEIVING OUR VEHICLE BACK FROM A MAZDA DEALER FOR WARRANTY REPAIRS ON THE PTU AND CONTROL ARMS, WE WERE DRIVING DOWN THE HIGHWAY AT 65 MPH - INITIALLY GOING UP A HILL IN THE MOUNTAINS. THE CAR WOULD NOT SHIFT GEARS (AN AUTOMATIC) AND THEN WOULD NOT ACCELERATE PAST 30 MPH. NO DUMMY LIGHTS LIT WHATSOEVER. WE GOT TO THE TOP OF THE HILL AND HAVING NO PLACE TO PULL OFF ON THE HIGHWAY MOUNTAIN SHOULDER, STAYED IN THE LANE OF TRAFFIC WITH OUR HAZARDS ON. THE DOWN SIDE OF THE HILL WAS A 6% GRADE WITH A CLIFF ON THE OTHER SIDE OF THE GUARD RAILS. ALL OF A SUDDEN - THE POWER STEERING WENT OUT AND THE CAR WAS HARD TO STEER. THERE WAS STILL NO PLACE TO PULL OVER ON THE MOUNTAIN HIGHWAY, SO WE COASTED. WE THEN NOTICED THE RPM'S WERE AT 0 AND ALL THE DUMMY LIGHTS THAT ARE ON WHEN THE CAR IGNITION IS IN ACCESSORY WERE LIT UP. THE CAR HAD TURNED OFF - WHILE WE WERE GOING 65 MPH ON A 6% GRADE. NO WARNING - NO SOUNDS, SMOKE, DUMMY LIGHTS - JUST OFF. VERY AMAZINGLY DANGEROUS. WE WERE VERY LUCKY TO NOT DIE A FIERY DEATH. MY HUSBAND WAS ABLE TO KEEP CALM AND THANKFULLY THE BRAKES WORKED - WE WERE ABLE TO STOP TOWARDS THE BOTTOM OF THE HILL. WE HAD THE CAR TOWED AS IT WOULDN'T START/STAY RUNNING. THE DIAGNOSIS BY THE DEALER (NOT THE DEALER WHO DID THE PRIOR WARRANTY WORK) WAS A FAILED ENGINE ROD. WOULD HAVE BEEN NICE TO GET A CHECK ENGINE LIGHT BEFORE HAVING THE CAR COMPLETELY SHUT OFF. WE DROVE THE VEHICLE FOR LESS THAN 100 MILES AFTER RECEIVING BACK FROM THE WARRANTY WORK AND NOW THIS.

THIS HAS OCCURRED MULTIPLE TIME AND WE HAVE TAKEN THE CAR TO THE DEALER A NUMBER OF TIMES WHO HAS INSPECTED IT AND EVEN KEPT IT AT THE SHOP DROVE IT FOR A NUMBER OF DAYS AND COULD NOT PINPOINT THE PROBLEM. WE HAVE MADE MAZDA USA AWARE OF THE ISSUE AND THE POTENTIAL THREAT OF THIS VEHICLE (THEY GAVE US A CASE # 149456450) HOWEVER, SADLY THEIR ATTITUDE IS THAT IF THE PROBLEM CANT BE PINNED THEN IT DOES NOT EXIST. THIS IS A CLEAR IGNORANCE ON MAZDA USA'S PART AND PUTTING THE PUBLIC IN A RISK WITH THIS VEHICLE. *TR

SEVERAL WEEKS AGO THE BRAKES STARTED MAKING A HISSING NOISE WHEN I WOULD DEPRESS THE BRAKE. THEN, THE CAR WOULD BRAKE AS USUAL UNTIL I NEEDED TO COME TO A COMPLETE STOP, WHEREAS THEN I WOULD NEED TO DEPRESS THE BRAKE VERY HARD TO MAKE THE CAR STOP, WHICH THEN IT WOULD STOP VERY SUDDENLY. THE MOST RECENT EVENT OCCURRED WHEN MY HUSBAND WAS DRIVING DOWN THE ROAD ABOUT 45 MPH AND HAD HIT THE BRAKES AND THE ENGINE COMPLETELY SHUT OFF, ALL THE WARNING LIGHTS CAME ON AND IT WAS VERY DIFFICULT FOR MY HUSBAND TO PULL THE CAR OVER AND COME TO A STOP. THE ENGINE DID START BACK UP AND WE DROVE ALL THE WAY HOME AND HAVE NOT SINCE DRIVEN THE VEHICLE. *TR

THE FIRST TIME I EXPERIENCED THIS TERRIFYING ORDEAL WAS IN NOVEMBER OF 2011. SINCE THEN, I HAVE HAD IT HAPPEN TWO MORE TIMES. THE CAR ACCELERATES OF UP TO SPEEDS OF 90 MPH WITHOUT WARNING . ALL 3 INCIDENTS HAVE HAPPENED ON THE HIGHWAY. THE BRAKES SLOW IT DOWN, BUT DO NOT STOP IT. ALL 3 TIMES, I'VE BEEN LUCKY ENOUGH TO GET THE CAR TO THE SHOULDER AND RIDE DOWN THE MEDIAN , PUSHING THE EMERGENCY BREAK IN AND AT ONE POINT PUSHING IT INTO PARK. MAZDA KNOWS ABOUT THIS. THEREFORE THEY ARE LIABLE. MAZDA WILL TELL YOU IT'S A THROTTLE PROBLEM, THEY WILL TELL YOU THERE IS NO WEAR ON THE BRAKES....WELL, THAT'S BECAUSE WHEN THE CAR DOES THIS UNEXPECTED ACCELERATION, THE BRAKES ONLY GO PART WAY..ALMOST LIKE PUSHING AGAINST AIR. THIS IS A SERIOUS PROBLEM WITH THE COMPUTER AND POSSIBLY THROTTLE COMBINED. MY CAR IS NOT FIXED, IT'S ALSO DOING OTHER STUFF. MAZDA WANTS ME TO KEEP THIS CAR AND DRIVE IT. THEY ARE GIANTS, SO THE LITTLE PERSON LIKE ME DOES NOT MATTER TO THEM IT'S THE $$$$. BUT WHEN SOMEONE DIES, IT WILL COST THEM $$$$$$$$$$. THERE NEEDS TO BE A RECALL. I HOPE MORE PEOPLE COME FORWARD. IT COULD SAVE YOUR LIFE OR/AND SOMEONE YOU LOVE AND OTHER DRIVERS ON THE ROAD WHO ARE IN DANGER OF YOU HURTING/KILLING THEM. MY MAZDA DEALERSHIP HAVE WONDERFUL PEOPLE WHO WORK THERE. THEY ARE VERY UNHAPPY WITH MAZDA NOT TAKING CARE OF THIS PROBLEM. I WANT TO MAKE THIS CLEAR, IT'S MAZDA CORP THAT IS AWARE AND DOING NOTHING AND THEY HOLD THE MAZDA DEALERS HOSTAGE. *TR
