2018 Mazda CX-9 complaints

I purchased my 2018 Mazda CX-9 Grand Touring CPO with 39k miles and was sold the life time extended powertrain warranty through the dealership. The car now has 74k miles. While sitting idle at the school bus stop in my neighborhood waiting for my daughter the temperature gauge light comes on. I immediately drive home (exactly 0.3 miles) not going over 10mph back home, park call a tow truck company to tow it to the Priority Mazda dealership in Tysons Corner, VA from which I bought it. After a few days the mechanic calls and tells me there is a coolant leak and the repairs for the Cylinder Head should be covered under my lifetime extended warranty. A few days later I get a text message from the service rep that states. "Unfortunately, the extended warranty has denied coverage of the Cylinder Head, stating it to not be an internally lubricated issue....we need to fully inspect to determine what is needed (cylinder head or full engine due to overheating) Cost of teardown $1,432." After speaking to the service rep directly he then tells me the coverage was actually denied because Mazda put out a TSB on this known issue which voided my extended warranty on the cylinder head. This TSB bulletin no.01-007/22 was just issued 2 months before this happened. We should not be responsible for a known engine issue on Mazda's flagship car after purchasing an extended warranty for this very reason.

Mazda has refused to admit and repair a clearly defective screen, affecting visibility of the camera system, navigation, climate controls and infotainment. Pictures attached are several months old and the issue continues to get worse. The dealer says "corporate won't cover it", corporate customer service will not respond to repeated attempts at contact other than a generic "your VIN is not covered". Service alert direct from Mazda and pictures of my screen showing the EXACT issue are attached. For a $40k+ vehicle with less than 30k miles on it (less than 20k when the issue started), this is unacceptable. Please hold Mazda accountable.

While commuting home on 8/19/22 my CX-9 began overheating and coolant temp. warning light illuminated on dash. This was a dangerous situation as I had to stop in the middle of traffic for fear of ruining my car and risk getting rear-ended and also navigate to the shoulder of the road. Took the car to the dealership where they confirmed P111A engine overheated DTC and coolant leak. CX-9 has a cracked cylinder head, the exact problem outlined in Mazda TSB 01-013/21. This happened at 61,xxx miles...roughly 1,000 miles outside the powertrain warranty however it's highly likely this crack and leak developed well before the end of the powertrain warranty period.

"Spider Cracks" in both the left and right top corners that continue to spread, creating larger blind spots while in reverse. This is an issue that Mazda is aware of and impacts many models from 2014 until 2019. Even though this may not be considered a "safety feature" in it's traditional form, it has become common practice to rely on this feature while reversing the vehicle. Much like additional airbags may not be required, if they are, they should be fixed when they are proven to be faulty. Both the local dealer(Roger Beasley Austin North) and MazdaUSA refused to cover the cost of fixing the issue even though they are aware it is faulty. There is even a Service Notice that was put out by NHTSA that discusses this issue and my model is included, however I have been repeatedly told my VIN # does not qualify.

Car starting misfiring . I was told it appears to have a crack in the head gasket & would be best to repair the engine . This car has only 80k miles and should NOT be doing this at this stage!!!

While driving the rear wheel trim piece went flying off and struck the car behind. Noting was loose, showed signs or issues beforehand and nothing was struck on the road. Online searching has shown this is an issue others have experienced.

The contact owns a 2018 Mazda CX-9, The contact received notification of NHTSA Campaign Number: 21V875000 (Gasoline, Fuel System) however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure. VIN tool confirms parts not available.

Had loss of coolant mid to late January 2022, which lead to over heating notifications. Upon inspection at dealer (Pacifico Mazda Philadelphia PA), it was determined that i had a cracked cylinder head. Initially dealer said they were to replace just the cylinder head & after about 1 week they said that the engine would be replaced. Received car back 4/06/22

The Mazda Connect information screen has small spider cracks on the upper right part of screen that are inside the glass (if you run your finger over the crack it feels smooth). Information websites pertaining to Mazda vehicles say it's caused by temperature change.

When this vehicle is low on fuel (but not empty) and under heavy acceleration, the fuel pump temporarily fails causing the engine to stall. This creates a serious safety hazard. Other 2019 Mazda models were covered for a similar defect under NHTSA Campaign Number 21V-875, however this specific VIN is questionably not included under that recall.

The contact owns a 2018 Mazda CX-9. The contact stated that while pulling up to a gas pump the vehicle lost motive power and stalled. The contact added gasoline to the vehicle, restarted the vehicle, and was able to continue to drive to her residence. Several weeks later the failure recurred while the contact was pulling into a parking lot. The check engine warning light illuminated. The contact’s husband arrived at the scene and added gasoline to the vehicle. The vehicle was restarted however, the check engine warning light remained illuminated. The vehicle was taken to the local dealer to be diagnosed. The contact was informed that the fuel pump and sensor were faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 65,000.

The Mazda connect touch screen has started cracking in the corners 3 so far the past 4 months. I cannot feel the cracks. They are spreading and I am concerned eventually I will not be able to use my navigation. System at all as I will not be able to read it. I am concerned the touch ability will be lost. I understand many other Mazdas have this same defect but my model is not covered under the extended warranty like the other Mazda owners were given - the extended warranty covers vehicles older than mine. It is the same defect.

Internal crack in center display. Mazda Mexico refuses to extend warranty since this model has not yet been called even though other previous models already have the warning

When I shifted into reverse the back up camera wouldn’t come on and instead a screen that said check your surroundings stayed on the screen. I reset it using the 3 button reset method and it came back on. Drove it to the grocery store, and then it sat in my driveway for 3 hours. When I went to go back in to town, the car was completely dead. No power whatsoever. We tried jumper cables and those didn’t work. Finally tried a battery charger and after an hour of charging it finally came back on. A car this new shouldn’t be having these issues.

Within 6-8 months of purchasing the car we noticed the brakes squeaking and vibrating. At that time the car was under 25,000 miles. At our maintenance check it was advised that we have the brakes resurfaced at the next appt. Back brakes were done in 3/2019 and the front were done in 6/2019. We noticed the squealing and vibration returned again. At our recent maintenance check, we asked to have the brakes and rotors inspected. We were told everything looked fine and nothing needed to be done, however we are still experiencing the vibration which is very troubling. We called another place explaining the issue and they said that it sounds like we need new rotors. Our car has mostly been sitting over the last year and a half with very few added miles. We're curious to know why a car with less than 25,000 miles on it needed the rotors resurfaced and why with less than 60,000 miles it needs new rotors. The brakes on the Mazda SUV's seem to wear rather quickly or perhaps the incorrect brakes are put on for this size of vehicle. The increased vibration seems like a safety hazard

HAPPENED TO ME TWO TIMES IN PAST THREE WEEKS, WHERE I AM COMING TO A STOP, OR HARDLY MOVING, AND CAR SUDDENLY ACCELERATES. HAD MY FOOT ON THE BRAKE AND THE CAR WAS STILL TRYING TO ACCELERATE. YESTERDAY, 4/24/21 IT TOOK ALL MY STRENGTH ON THE BRAKE TO KEEP THE CAR FROM PULLING INTO ONCOMING TRAFFIC. I HAVE BEEN DRIVING FOR 39 YEARS AND HAVE OWNED MANY CARS, AND SOMETHING LIKE THIS NEVER HAPPENED TO ME. I WILL BE BRING THE CAR DEALERSHIP TOMORROW, THE CAR HAS ONLY 10K MILES ON IT AS WE DON'T DO A LOT OF DRIVING WITH IT AS WE OWE TWO CARS. I DID NOT HAVE MY FOOT ON THE WRONG PEDAL, THIS IS VERY DANGEROUS AND IF THE DEALER DOES NOT FIND ANYTHING WITH THE CAR, I INTEND TO SELL IT, AS THIS IS PROBABLY ONE OF THE SCARIEST EXPERIENCE I HAD WITH A CAR. IT IS INTERMITTENT, SO I AM NOT SURE WHEN ITS GOING TO OCCUR, BUT TWICE IN THE LAST FEW WEEKS IS NOT COINCIDENCE ( IT ALSO HAPPENED TO MY WIFE A FEW MONTHS AGO, BUT WE THOUGHT IT COULD HAVE BEEN DUE TO SNOWY ROAD CONDITIONS). IN ONE CASE I WAS COMING UP TO A STOP SIGN, AND WAS BRAKING AND CAR WAS ACCELERATING AS I TRIED TO BREAK. I HAD TO PUT CAR IN NEUTRAL AND THE SHUT OFF CAR TO GET TO STOP. YESTERDAY, I WAS PULLING OUT OF A PARKING LOT, AND WAS WAITING FOR AN ON COMING CAR TO PASS ME BEFORE I COULD TURN ONTO ROAD, WHEN CAR WAS TRYING TO ACCELERATE, WHEN I HAD MY FOOT ON BRAKE, AND TOOK EVERYTHING TO KEEP THE CAR FROM ACCELERATING FORWARD INTO ON COMING CAR. ONCE CAR PASSED, I MADE TURN ONTO ROAD, AND ISSUE DID NOT REPEAT ON THE REMAI

EPB WILL NOT RELEASE, OR WILL UNEXPECTEDLY AND SUDDENLY RELEASE WITH CAR ACCELERATING IN GEAR ('DRIVE' OR 'REVERSE'). MOST RECENTLY WHEN ACTIVATING THE EMERGENCY PARKING BRAKE ((CAR WAS ON A A ROADWAY INCLINE) THE BRAKE WOULD NOT RELEASE, AFTER 2 HOURS OF BEING STRANDED AND OF ATTEMPTING TO GET THE BRAKE TO RELEASE, ( INCLUDING ROCKING/SHIFTING/ALTERNATING GEARS/BRAKING/SEAT BELT ON/SEAT BELT OFF/ MANUAL BRAKE ON/OFF AND FOLLOWING ALL MANUAL PROCEDURES REPETITIVELY) A CELL PHONE CALL TO THE MAZDA SERVICE MANAGER WHO SUGGESTED ROCKING THE CAR BACK AND FORTH BETWEEN GEARS ) THE EMERGENCY PARKING BRAKE SUDDENLY AND UNEXPECTEDLY 'RELEASED', SENDING THE CAR LURCHING FORWARD AND REQUIRING DRIVER TO SLAM ON BRAKES TO AVOID DRIVING OVER A CLIFF). VEHICLE EPB INSPECTION REQUESTED, MAZDA SERVICE MANAGER STATED THE EPB IS, 'NO LONGER NECESSARY FOR VEHICLE SAFETY', BLAMED THE MALFUNCTION ON 'BREAD CRUMBS' , OFFERED TO REPLACE A DEFECTIVE CONSOLE SWITCH (PRESUMABLY WITH ANOTHER NEW, BUT ALSO DEFECTIVE, SWITCH) BUT REFUSED TO INSPECT THE MECHANICAL/OPERATIONAL ASPECTS OF THE AUTOMATIC EMERGENCY PARKING BRAKE SYSTEM (FOR ABNORMAL RUST, WATER LEAKS, DEFECTIVE CABLES, DEFECTIVE ELECTRICAL WIRING, ETC.).

I'M CONSTANTLY HAVE A FRONT WINDSHIELD ERROR : CAUSING MY VEHICLE TO JUST AUTOMATICALLY STOPING WHILE DRIVING ON THE FREEWAY AND STREETS. MY AIR BAGS DIDN'T DEPLOY WHEN I WAS I A ACCIDENT . I'VE TAKEN IT TO THE DEALER 3 TIMES ALREADY AND THEY ALWAYS HAVE A DIFFERENT EXCUSE OR REASON

I WANTED TO SAY IT HAPPENED TO US WHILE WE WERE DRIVING BACK FROM A DAYTRIP ON SATURDAY. WE HAD OUR KIDS IN THE CAR AND MY HUSBAND WAS DRIVING. ALL OF A SUDDEN THE SCBS LIGHT CAME ON AND THE CAR JUST STOPPED GIVING GAS. THE CAR BEHIND US COULDN'T TELL WE WERE SLOWING DOWN BECAUSE THERE WAS NO BRAKE LIGHT. WE WERE ALMOST REAR ENDED. THE CAR BEHIND US COULDN'T STOP IN ENOUGH TIME SO THEY JUST SWERVED ONTO THE OTHER SIDE OF US. WE HAD TO PULL THE CAR OVER AND IT WAS ALMOST NIGHTTIME. MY HUSBAND ENDED UP PUSHING THE CAR TO GET IT OFF THE ROAD AND TO A SAFE PLACE. IT WOULD ONLY GO 2 MILES PER HOUR. I HAD MY CAR TOWED TO THE DEALERSHIP, I HAVE NOT HEARD ANYTHING FROM THEM EXCEPT THEY ARE CONTINUING TO LOOK INTO IT. IT'S A 2018 MAZDA CX9 WITH ONLY 26000 MILES. IT'S NEVER BEEN IN AN ACCIDENT. I'M HOPING THAT WHATEVER THE FIX IS, IT'S COVERED UNDER WARRANTY. IF IT WAS A TRUCK OR BUS BEHIND US, THEY WOULD NOT HAVE BEEN ABLE TO STOP EITHER. IF WE WERE ON A HIGHWAY AND THIS HAPPENED, THERE IS NO DOUBT IT WOULD HAVE CAUSED AN ACCIDENT.

I WAS PULLING INTO A PARKING SPOT IN THE UPPER PARKING LOT AT WORK. I STEPPED ON THE BRAKE PEDAL SO THAT I COULD STOP AND PARK BUT THE PEDAL WAS HARD AND HAD NO GIVE. THE CAR CONTINUED TO ROLL FORWARD OVER A CURB AND PARTLY DOWN A SMALL SET OF STAIRS THAT GO FROM THE UPPER PARKING LOT TO THE LOWER PARKING LOT. THE CAR STOPPED WHEN IT HIT A METAL RAILING AND I SHIFTED THE CAR INTO PARK.

TAKATA RECALL - WAS IN A HEAD ON COLLISION WITH 3 OTHER CARS INVOLVED, ALL CARS WERE TOTALED AND ALL OF THE OTHER CARS' AIRBAGS DEPLOYED WITH THE EXCEPTION OF MINE AND I WAS INJURED AS A RESULT.

CAR SHOWED IGNITION ON WHEN THE CAR WAS TURNED OFF. SAME DAY WHILE DRIVING ON HIGHWAY CAR ENGINE REVVED FOR NO REASON. ALSO WHEN SOMEONE GOT OUT OF PARKED CAR IT SAID NO KEY DETECTED BUT CAR WAS STILL TURNED ON AND KEY WAS RIGHT BESIDE ME.

I WAS WAITING IN A STATIONARY POSITION, AT A RED LIGHT, BEHIND SOME OTHER VEHICLES, WITH MY FOOT ON THE BRAKE PEDAL. ALL OF A SUDDEN, THE VEHICLE STARTED TO LURCH FORWARD AS IF SOMEONE HAD STEPPED HARD ON THE GAS PEDAL! I WAS STRUGGLING TO KEEP THE CAR STILL BY DEPRESSING THE BRAKE PEDAL HARDER, BUT IT WOULDN'T STOP THE CAR. I HAD TO PUT IT IN PARK AND TURN OFF THE ENGINE TO STOP THE FORWARD THRUST OF THE VEHICLE.

THIS VEHICLE IS HAS BEEN ON LEASE FOR 1 YEAR AND HAS LESS THAN 4000 MILES ON IT. INITIALLY WHILE ATTEMPTING TO START THE VEHICLE THAT HAD BEEN PARKED OVERNIGHT IT GAVE THE FOLLOWING WARNINGS: - KEYLESS ENTRY MALFUNCTION - CHARGING SYSTEM MALFUNCTION - VEHICLE OVERHEATING - BATTERY MALFUNCTION THE CAR WOULD NOT SHUT OFF UNTIL I HELD THE START/STOP BUTTON IN FOR ROUGHLY 20SECS. THE DEALER SERVICE CENTER TOOK THE CAR AND TOLD US THE BATTERY HAD A LOW CHARGE, CHARGED IT AND RETURNED IT. SEVERAL WEEKS LATER WHILE THE VEHICLE WAS IN MOTION WITH 2 ADULTS AND 2 CHILDREN ON A CITY STREET TRAVELING AT ABOUT 20MPH IT GAVE THE FOLLOWING WARNINGS: - KEYLESS ENTRY MALFUCTION - CHARGING SYSTEM MALFUCTION - VEHICLE OVERHEATING - BATTERY MALFUNCTION - PULL OVER TO SAFETY AT THIS POINT THE VEHICLE WAS STILL IN MOTION AND THE STEREO, HVAC, AND POWER STEERING CUT OUT. I WAS ABLE TO PULL THE VEHICLE OVER BUT AGAIN HAD TROUBLE SHUTTING IT OFF. I HAD TO HOLD THE START/STOP BUTTON FOR 20-40SECS. THE CAR WAS TOWED TO THE DEALER SERVICE CENTER. WE WERE TOLD BY THE SERVICE CENTER THAT A LOT OF 500 VEHICLES OF THIS YEAR AND MODEL HAD AN ENGINE HARNESS DEFECT THAT NO RECALL HAD BEEN ISSUED FOR BUT THEY WERE AWARE OF DEFECT AND HAD A FIX FOR IT. I FEEL I WAS LUCKY THAT I WAS ONLY TRAVELING 20MPH WHEN THE POWER STEERING CUT OUT. IF I HAD BEEN TRAVELING HIGHWAY SPEEDS ON A BEND THE SITUATION COULD HAVE BEEN TRAGIC AND I HAD MY CHILDREN IN THE CAR. CURRENTLY, BASED ON WHAT I'VE BEEN TOLD BY THE DEALER SERVIC

WHILE DRIVING THE VEHICLE THE CAR TO AN ABRUPT STOP AND I HAD NO CONTROL. THE DASHBOARD LIT UP WITH ALL TYPES OF WARNINGS AND HEAT WAS COMING FROM THE FRONT OF THE CAR.

ON FRIDAY (JUNE 29TH, 2018) AROUND 9:29 PM, MY CAR BROKE DOWN WHILE MY FAMILY AND I WERE TRAVELING FROM ROCHESTER NY TO BOSTON MASSACHUSETTS. I WAS DRIVING DOWN THE MASSACHUSETTS TURNPIKE WHEN ALL OF A SUDDEN MY CHECK ENGINE LIGHT TURNED ON AND MY CAR JUST STARTED TO SLOW DOWN IN THE MIDDLE OF THE HIGHWAY. I WAS ABLE TO PULL OVER IN TIME AND CALLED MAZDA ROADSIDE ASSISTANCE BECAUSE AFTER THE CAR STOPPED, IT WOULDN'T TURN BACK ON. SINCE WE WERE ON A RESTRICTED HIGHWAY, MY CAR HAD TO BE TOWED AND WE WERE TAKEN TO A SAFER LOCATION. WHEN THE CAR WAS PUT DOWN, IT TURNED ON AND THE CHECK ENGINE LIGHT WAS STILL ON AND THE FUEL GAUGE SAID THAT THE CAR STILL HAD 40 MILES LEFT. THE GUY THAT TOWED OUR CAR SAID THAT IT MIGHT HAVE BEEN A FUEL ISSUE, SO WE WENT TO GET GAS. ONCE WE FILLED UP OUR TANK THE CHECK ENGINE LIGHT WAS STILL ON BUT WE WERE ABLE TO REACH OUR DESTINATION. THE NEXT MORNING, I TOOK THE CAR TO THE NEAREST MAZDA DEALERSHIP AND THEY RESTARTED THE CAR AND ACCORDING TO THEIR REPORT NOTHING WAS WRONG WITH THE CAR. THEY SAID THAT IT WAS SAFE TO DRIVE BUT THEY HAD NO CLEAR REASON AS TO WHY THE FUEL GAUGE WASN'T STATING THE CORRECT INFORMATION. AFTER THE TRIP I, REPORTED THIS ISSUE TO MAZDA AND THEY DIDN'T ANSWER ME UNTIL TWO WEEKS LATER. THEIR RESPONSE WAS THAT THERE WAS PROBABLY NOTHING WRONG WITH THE VEHICLE AND THAT THIS WAS A ONE TIME ISSUE. I DID RESEARCH ON MY OWN AND DISCOVERIES THAT SOMEONE FROM SAUDI ARABIA HAD A SIMILAR ISSUE. SINCE MAZDA HASN'T BEEN WILLING TO HELP R

I PURCHASED A NEW MAZDA CX-9 IN SEPT 2017 BECAUSE IT HAD THE HIGHLY TOUTED SMART CITY BRAKING SYSTEM FOR WHICH I PAID THOUSANDS EXTRA. I HAD HAD A PREVIOUS REAR END COLLISION AND WANTED TO BE SURE THIS SYSTEM WOULD AT LEAST WARN ME. I SET UP SOME CARDBOARD BOXES WRAPPED IN ALUMINUM FOIL. I SLOWLY (10 MPH) DROVE THE CAR INTO THEM WITHOUT TOUCHING THE BRAKE OR ACCELERATOR. THE CAR DID NOT SLOW DOWN OR WARN ME.(I TRIED SENDING A VIDEO TO YOU FROM MY IPHONE WHICH MAY NOT GO THROUGH) I MADE AN APPOINT TO REPAIR THIS OBVIOUS FACTORY DEFECT AND SIGNIFICANT SAFETY ISSUE. THE SERVICE MANAGER AT OLYMPIA LINCOLN /MAZDA(AND PUYALLUP MILAM MAZDA) REFUSED TO REPAIR IT THEY STATED AND SHOWED ME A PRINT OUT FROM MAZDA FACTORY THAT FORBIDS REAL TIME TESTING AND STATED THAT IF THE TROUBLE LIGHT IS NOT ON THEY AREN'T ALLOWED TO REPAIR OR REAL TIME TEST IT. I THINK THAT THE FACTORY IS AFRAID OF DEALING WITH A MASSIVE SAFETY RECALL. TO COMPOUND THINGS THE ACTIVE LIVE TRAFFIC DISPLAY DOESN'T WORK EITHER WHICH MAKES MATTERS WORSE SINCE I CAN'T SEE WHERE AN ACCIDENT HAS OCCURS IN REAL TIME. I UNDERSTAND ITS DEFECTIVE IN MOST MAZDAS WITH NAVIGATION IN 2016 AND BEYOND. THE IS A CLASS ACTION LAW SUIT STARTING TO BE FILED ABOUT THIS. *BF CONSUMER STATED REGARDING DEFECTIVE AUTOMATIC BRAKING SYSTEM ON 2018 MAZDA CX-9. I HAVE NOT HEARD BACK AFTER FILING THIS COMPLAINT 2 MONTHS AGO. UPDATED 8/24/18*JB
