2010 MAZDA CX-9 Complaints

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.

HISSING SOUND WHEN BREAK PEDAL IS APPLIED. POWER BREAK BOOSTER FAILURE. THIS IS WHEN THE VEHICLE IS STATIONARY OR MOVING ON ANY STREET.

THE VEHICLE SUDDENLY LOST BRAKING POWER, AND THE BRAKE PEDAL WOULD SOMETIMES FEEL "SPONGY" AND SOMETIMES FEEL ROCK-HARD, WITH VARYING RESULTS FOR BRAKING POWER. I WENT TO A MECHANIC WHO SAID THE BRAKE BOOSTER FAILED, AND WE FOUND THIS WAS A KNOWN PROBLEM WITH THE MAZDA CX-9, HOWEVER NHTSA'S INVESTIGATION WAS RESOLVED WHEN MAZDA COVERED THIS PROBLEM FOR ONE YEAR FROM THE DATE IS CLOSING THE NHTSA INVESTIGATION. THIS APPARENTLY IS STILL A PROBLEM, THOUGH. I CALLED MAZDA'S CUSTOMER SERVICE, AND THEY REFUSED TO ACKNOWLEDGE THIS PROBLEM EXISTED AND WOULD ONLY GIVE THE SCRIPTED "THERE ARE NO OPEN RECALLS ON YOUR VEHICLE".

BRAKE BOOSTER SPONGY...KNOWN MAZDA ISSUE,NHTSA CLOSED ISSUE WHEN MAZDA AGREED TO EXTEND WARRANTY,WITHOUT RECALL. OUR PROBLEM OCCURRED AFTER WARRANTY ENDED...PROVING BRAKE RECALL NEEDS TO HAPPEN!!!! ON JULY 1ST,2020, MY WIFE'S TRIP BACK HOME NEARLY TURNED TRAGIC WHEN THE CAR WOULDN'T BRAKE(FELT SPONGY) DOWN THE HIGHWAY RAMP . FORTUNATELY FOR HER ,THERE WERE NO CARS AT THE INTERSECTION AS THE CAR ZOOMED RIGHT AT 60 MPH .EVENTUALLY,SHE WAS ABLE TO MANEUVER IT TO THE RIGHT LANE AND DROVE IT HOME WITH HAZARD LIGHTS ON. RIGHTFULLY DISTRAUGHT ABOUT THE WHOLE ORDEAL ,WE HAD TO THANK OUR STARS FOR HAVING HER HOME ALIVE AND WITHOUT CAUSING INJURY/DEATH TO OTHERS. ON MY DRIVE TO THE MECHANICS I HEARD AIR HISSING AND FELT THE BRAKE REALLY HARD TO PUSH. AGAIN HAZARD LIGHTS/ MANUAL DRIVE GOT US THERE. THE MECHANICS IMMEDIATELY SUGGESTED THAT THIS IS A KNOWN PROBLEM WITH MAZDA CX-9 AND THAT MAZDA WAS AWARE OF IT. HE SAID THAT MAZDA HAD PROVIDED EXTENDED WARRANTY FOR CUSTOMERS WHO HAD THE ISSUE UNTIL MARCH 2015. WE WERE GROSSLY UNAWARE OF ANY OF THIS,AS WE NEVER HAD THE PROBLEM UNTIL THIS JULY. NOT SURE HOW WE WENT ON FOR SO LONG WITHOUT ANY PROBLEM( MAY BE PROPER CARE/USE?),BUT ANY ISSUE WITH A BRAKE SHOULD HAVE BEEN ADDRESSED BY A COMPLETE RECALL ,NOT BY JUST PROVIDING EXTENDED WARRANTY FOR A LIMITED TIME ,JUST FOR PEOPLE CURRENTLY EXPERIENCING THE ISSUE.MAZDA CUSTOMER SERVICE DOWNPLAYED THE COMPLAINT AS OWNER'S EXPENSE AS WE DID NOT HAVE THE WARRANTY. OUR SITUATION PROVES THAT BRAKE ISSUES ARE NOT SOLVED BY EXTENDING WARRANTY,AND THE ONLY WAY TO ADDRESS THIS IS BY ISSUING A RECALL AND CORRECTING THE PROBLEM. IN ADDITION, THERE MIGHT BE MANY MORE MAZDA OWNERS STILL DRIVING THEIR VEHICLES,COMPLETELY UNAWARE OF THIS PROBLEM,THUS CONSTITUTING HAZARDOUS DRIVING CONDITIONS. THE NEXT TIME WE MIGHT NOT BE AS LUCKY TO ESCAPE WITHOUT INJURY/DEATH.

TL* THE CONTACT OWNS A 2010 MAZDA CX-9. THE CONTACT STATED THAT WHILE DRIVING 25-30 MPH, THE VEHICLE SHUTOFF WITH THE CHECK ENGINE WARNING LIGHT ILLUMINATED. THE CONTACT CHECKED UNDER THE HOOD AND NOTICED THE COOLANT RESERVOIR WAS EMPTY. THE CONTACT PUSHED THE VEHICLE TO HER RESIDENCE. THE CONTACT STATED THAT THE NEXT DAY SHE NOTICED COOLANT MIXED IN WITH THE ENGINE OIL. THE CONTACT CALLED JACK GIAMBALVO MAZDA (2425 INDUSTRIAL HWY, YORK, PA 17402, (717) 755-2944) AND WAS INFORMED THAT THE FAILURE MAY BE THE WATER PUMP HOWEVER, THE VEHICLE WAS NOT DIAGNOSED NOR REPAIRED. THE FAILURE MILEAGE WAS 127,422. THE WATER PUMP WAS PREVIOUSLY REPLACED AT 61,000.

I'VE HAD EVERYTHING REPLACED ON MY CAR FOR THE AIR SYSTEM. WHEN I'M TRAVELING THE AIR SEEMS TO WORK FINE. WHEN THE CAR IDOL'S FOR MORE THAN LIKE 5 MIN THE AIR STARTS BLOWING WARMER AND WARMER. HAD THE CAR TAKEN IN MORE THAN ONCE FOR THIS AND THEY HAVE REPLACED DIFFERENT THINGS. THE PROBLEM STILL KEEPS HAPPENING. I HAVE READ WHERE OTHER PEOPLE HAVE THE SAME PROBLEM. HAS THERE BEEN ANY FIX FOR THIS BEING I'M NOT THE ONLY ONE WITH THIS PROBLEM?

WHEN DRIVING, 40-45 MPH THE TRANSMISSION STARTS JERKING AND SHUTTERING. FINALLY MAKES IT TO 5TH GEAR. THEN DOES THE SAME THING WHEN SHIFTING FROM 5TH TO 6TH GEAR. WHEN THIS HAPPENS THE ENTIRE SUV STARTS SHAKING AND JERKING. FEAR COULD CAUSE LOSS OF CONTROL OF THE VEHICLE. *TR

TL* THE CONTACT OWNS A 2010 MAZDA CX9. THE CONTACT STATED WHILE DRIVING AT 5 MPH AROUND A ROUNDABOUT, THE PASSENGER'S SIDE FRONT TIRE DETACHED INDEPENDENTLY WITHOUT WARNING. THE VEHICLE WAS TOWED TO MODERN MAZDA,68 WATERBURY RD, LJ CT 06787 BUT WAS NOT DIAGNOSED. THE DIAGNOSIS AND REPAIR WAS STILL PENDING. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND A CASE WAS OPENED. THE APPROXIMATE FAILURE MILEAGE WAS 135,000.

ABOUT 1 MONTH AGO I NOTICED MY CAR MAKING A HISSING SOUND WHEN MY FOOT WAS ON THE BRAKE PEDAL AT A RED LIGHT OR STOP SIGN. IF I WAS A LONG RED LIGHT OR IN A DRIVE THRU FOR MORE THAN 5 MINUTES I NOTICED MY CAR WOULD BEGIN TO TREMBLE. THEN ABOUT A WEEK AGO I NOTICED IF I HAD TO BRAKE SUDDENLY, THE BRAKE PEDAL WAS VERY HARD TO PUSH DOWN MAKING IT ALMOST IMPOSSIBLE TO STOP. I TOOK THE CAR TO THE DEALER ON 2/3/2020 AND THE TECHNICIAN MENTIONED THAT THEY HAVE BEEN HAVING PROBLEMS WITH THE BRAKE BOOSTER.

THERE ARE NOISES COMING FROM THE FRONT TIRES, WHEN DRIVING. NO ONE COULD PINPOINT THE PROBLEM. BRAKE BOOSTER WENT OUT A COUPLE MONTHS LATER.
