2014 MAZDA CX-9 Engine Problems

I purchased a 2014 Mazda CX-9 back in May of 2020 w/ roughly 60k on the dash. Literally 7 months later w/ about 72k on the dash, the day after Christmas I was driving to work (I worked in the next state over) on the highway my car just shut down. No warnings, no check engine lights NOTHING! It just completely shut off and would not turn on. Thankfully because of the holiday the highway was pretty empty and I was able to swing my car across the interstate so I wouldn’t get hit by oncoming traffic. After getting out and deciding to check my oil I noticed it looked milky. I had no idea what that meant so I had it towed to a Mazda dealership in the state I live in. It was going to cost me almost $8,000 to put in a new engine because the water...

The water pump failed causing water to mix with the oil and damage the head gasket. Estimates recommend replacing engine. The service engine light came on and we took it to our trusted mechanic right away. Got the estimates from two mechanics for this repair and then towed the car to Mazda dealer who confirmed the problem. We wrote to Mazda's corporate office and was told they would not fix it. My car has 68,000 miles and was regularly serviced. It is currently sitting dead in my garage. We bought this car in 2015 brand new from the Mazda dealer in Monroeville, PA. This is outrageous! I spoke with someone else who also owns a Mazda and the same thing happened to his car. From articles I have read and attached, this problem is occurring in many Mazdas. What needs to be in place for Mazda to take responsibility and...

Water pump failed and ruined the engine. There was little to no warning.

I bought a vehicle from Carvana 11/2021 with not quite 59k on it. On 6/21/2023, with 77K miles, my car had a catastrophic engine failure. I was driving my grandchildren ages, 3-12 years of age home. Safety was definitely at risk with speeds of 70 freeway were completed right before engine stopping. The mechanic shop has confirmed the car giving 3 codes related to timing belt/water pump and the other code which confirms engine failure. No warning lights had come on until I tried to restart it. Since this situation is most recent, I have not had anyone else inspect the vehicle. I am working through my options and will take recommendations for resolution.

My transmission is slipping ….

Sudden failure of water pump located inside the engine caused engine to shut down immediately while driving 70 mph on busy expressway. Extremely dangerous situation due to heavy traffic and high speeds traveled. Only by sheer luck were we able to coast across 4 lanes of traffic to an exit ramp and barely make it into a parking lot after crossing 2 more lanes on the frontage road. Very difficult to steer and brake due to no engine power. Repair cost was $4,433. Two subsequent follow up repairs for check engine light and oil control valve issues related to water pump failure were required and covered under initial repair warranty. Research on web indicates this is a common problem with this engine with many complaints occurring soon after 100k miles. In many cases customers reported having to replace the engine or sell the car for parts due to the high...

Water pump defect that led to pump failure, which led to catastrophic engine failure without any prior warning. The defect is in the internal chain-driven water pump. The pump is meant to circulate coolant through the engine while the engine is running. However, the defect allows coolant to leak from water pump into the oil pan and/or other engine components, mixing it with the engine’s oil and leading to destruction of the engine. Mazda’s internal data indicates that the company began receiving reports of premature water pump failures in vehicles identical to mine (mine is a 2014 Mazda CX-9) by at least June 2007, yet Mazda continued to sell the vehicle without fixing the defect and failed to warn customers of the defect. The owner's manuals say nothing about water pump maintenance because the water pump should last the life of the Mazda vehicle. My water pump failed and destroyed...

- Water pump failed causing coolant to mix with oil. This repair cost was around $3,900. - Luckily this failure happened on our community road and was able to pull into our driveway. Mechanic stated that if this happened on the highway or regular road, this could have caused a major incident and possibly a blown motor. - No, but complaints of similar issues have been reported via my online research. - Just by the mechanic I had my vehicle towed to. - There was no indication of an issue until the water pump failed.

I purchased a 2014 Mazda CX-9 on 12/14/2019. On Monday 10/18/2021 I was driving on the Hwy on the way home and my check engine light came. I had my mechanic check it out and he said the computer read a P0019 code. So on 10/20/2021, I took it to the dealer where I originally purchased it and this was the same code they found. At the local dealership, I was told that apparently, the water pump needed to be replaced due to water coolant in the oil pan. I had absolutely no warning. No leaking, no smell of coolant. This vehicle only has 88,000. Upon further research and to my surprise is that the water pump in the Duratec 37 engine and make and model has a design flaw with the water pump located in the engine with the timing chain. That is the number one problem that fails...

I PURCHASED A 2014 MAZDA CX NINE A YEAR AND A HALF AGO. THE OTHER DAY I WAS DRIVING AND I DON'T KNOW WHERE MY FAN GOT REALLY LOUD SO I PULLED OVER AND TURNED UP THE HEAT AND TURNED OFF ANY AC. ALL THE SUN STEAM STARTED COMING OUT OF MY ENGINE AND THE CAR DIED. AFTER TOWING IT TO THE LOCAL DEALERSHIP I WAS TOLD THAT I HAD TWO OPTIONS. I COULD EITHER BUY A BRAND NEW CAR OR PAY $13,000 TO HAVE IT REPAIRED. APPARENTLY THE WATER PUMP BROKE AND THE ENGINE SEIZED UP. I HAD ABSOLUTELY NO WARNING. NO LEAKING, NO CHECK ENGINE LIGHT, NOTHING' I LATER FOUND SEVERAL REVIEWS SAYING THIS WAS AN ISSUE WITH THIS MAKE & MODEL. I STILL OWE OVER $16,000 ON THIS CAR AND NOW I HAVE TO GET A NEW CAR.

TL* THE CONTACT OWNS A 2014 MAZDA CX-9. CONTACT STATED THAT WHILE DRIVING AT 40 MPH, THE VEHICLE DECELERATED AND THE STEERING CEASED WITHOUT WARNING.

THE WATER PUMP FAILED ON THE VEHICLE AND COOLANT LEAKED INTO THE ENGINE OIL. THE VEHICLE ALL OF A SUDDEN STARTED SHAKING, THE ENGINE SHUT OFF AND THE VEHICLE LOST POWER. THE ENGINE IS NOW DAMAGED BEYOND REPAIR. THE VEHICLE HAS AN INTERNAL WATER PUMP AND THE OWNER'S MANUAL DOES NOT RECOMMEND ANY MAINTENANCE TO THE WATER PUMP. THIS VEHICLE HAD ALL OF THE RECOMMENDED MAINTENANCE COMPLETED AT AN AUTHORIZED MAZDA DEALER, THE VEHICLE WAS IN A PARKING LOT WHEN THE ENGINE UNEXPECTEDLY SHUT OFF. WHILE NO ONE WAS INJURED WHEN THE VEHICLE LOST ALL POWER AND THE ENGINE SHUT OFF, IT IS SOMETHING THAT SHOULD BE LOOKED INTO.

I NOTICED A ROUGH NOISE WHEN I STARTED THE 2014 MAZDA CX-9. I CHOSE TO IGNORE IT THINKING IT WAS BECAUSE OF THE COLD WEATHER. GOT TO THE HIGHWAY ON THE WAY HOME TO KANSAS CITY FROM COLUMBUS, OH. SEVERAL MILES LATER WHEN FILLING GAS, I NOTICED A WEIRD SMELL LIKE THAT OF A BURNING RUBBER OR COOLANT. THE CAR GOT ME HOME SAME BUT I NOTICED SLIGHT SMOKING FROM THE ENGINE WHEN I GOT HOME.TOOK IT TO THE MECHANIC AND HE ADVISED IT WAS THE WATER PUMP. HE DIDNT HAVE THE RIGHT TOOLS TO REPLACE IT SO I TOOK IT TO A MAZDA DEALERSHIP WHO ADVIED GETTING A NEW ENGINE. IT'S BEEN OVER THREE WEEKS AND I'M STILL WAITING OR THE DEALERSHIP TO FIND AN ENGINE THEY COULD REPLACE WITH. TOTAL COST, $4K - $5K. EXTREMELY FRUSTRATED THAT MAZDA WOULDNT RECALL CARS WITH THIS TYPE OF ENGINE/ WATER PUMP...

MY WIFE TOOK OUR 2014 MAZDA CX-9 TO LIBERTY MAZDA FOR A CHECK ENGINE LIGHT THAT CAME ON THE EVENING BEFORE SHE ALREADY AND AN APPOINTMENT FOR ANOTHER ISSUE. SHE ASKED THEM TO CHECK THE LIGHT AS WELL. AFTER THEIR FINDINGS THEY TOLD SUE THE CAR HAD A CATASTROPHIC WATER PUMP ENGINE FAILURE. THIS WATER PUMP IS LOCATED INSIDE THE TIMING CHAIN COVER AND LEAKS COOLANT IN TO THE ENGINE. AT THIS POINT WE WERE HANDED OVER TO A SALES REP. WHO INFORMED US THIS WAS A FOOLISH DESIGN WITH THE WATER PUMP LOCATED IN THE POWERTRAIN BEHIND THE TIMING CHAIN COVER. THIS CAUSES CATASTROPHIC ENGINE FAILURE WITH NO WARNING THIS IS WRONG AND SHOULD NOT HAPPEN. WE TALKED TO JASON THE SALES MANAGER WHO REITERATED THE SAME MESSAGE AND SAID HE WOULD PUT IN A GOOD WORD FOR ME IF COOPERATE CALLED ABOUT MY COMPLAINT. HE DID AND COOPERATE...

THE ENGINE SPUTTERED AND STOPPED WITHOUT WARNING WHILE DRIVING. IT TURNED OUT THE WATER PUMP WENT OUT AND SPILLED WATER INTERNALLY IN THE ENGINE. THE CAR HAS 73,000 MILES ON IT AND IT APPEARS THAT THIS HAS BEEN HAPPENING TO OTHER OWNERS OF THIS VEHICLE ROUTINELY, AND MAZDA HAS KEPT THIS DESIGN FLAW AND SAFETY CONCERN A SECRET. IT IS COSTING OVER $2,200 TO REPAIR, AND I BELIEVE THAT MAZDA SHOULD BE HELD ACCOUNTABLE FOR IT. THANK YOU.

I WAS SLOWLY APPROACHING A STOP LIGHT WHEN OUR 2014 MAZDA CX-9 STARTED HAVING VIBRATIONS, WHICH AT FIRST CAME FROM UNDERNEATH, BETWEEN THE DRIVER'S ROW AND THE 2ND ROW PASSENGER. IT IMMEDIATELY FELT AS IF THE CAR'S ENGINE WAS ABOUT TO FAIL. I MANAGED TO MAKE THAT RIGHT TURN, CAREFULLY STEPPING ON THE BRAKES, AND CROSSED A RAIL-ROAD CROSSING. THE CAR WAS RUNNING AT A SPEED OF 20 MPH. I SLOWED DOWN TO MAKE ANOTHER RIGHT TURN TOWARDS MY DESTINATION, THEN THE ENGINE ABRUPTLY DIED. THE BATTERY AND CHECK ENGINE LIGHTS SUDDENLY LIT UP ON THE DASHBOARD. FROM THE INTERSECTION'S STOP LIGHT TO THE LOCATION WHERE THE ENGINE FAILED, IT WAS A DISTANCE OF APPROXIMATELY 0.5 MILE. MY WIFE CAME AND PICKED UP OUR 3 CHILDREN FROM THE CORNER OF THE STREET. MY BROTHER-IN-LAW CAME TO MY LOCATION WITH JUMPER CABLES AND GAVE MY ENGINE'S BATTERY A JUMP-START. THE ENGINE...

I STARTED MY CAR AT HOME TO ALLOW IT TO WARM UP WHILE I GOT THE KIDS READY FOR SCHOOL. MY CARS STARTS WITH KEYFOB (NO KEY) ONCE WE WAS ALL READY WE LEFT HOME TO GO TO SCHOOL. I PROCEEDED TO DRIVE MY CAR TO THE SCHOOL (WITHOUT THE KEYS, APPARENTLY I LEFT THEM ON THE TABLE AND FORGOT TO GRAB THEM) WE ARRIVED AT THE SCHOOL. I PARKED, TURNED THE CAR OFF AND ENTERED THE BUILDING. WHEN I RETURNED TO LEAVE, I WAS UNABLE TO SINCE I DID NOT HAVE MY CAR KEYS.
