2010 MAZDA CX9 Complaints

THIS IS REGARDS TO THE MAZDA BRAKE BOOSTER ISSUE FOR THE 2010-2011 CX-9. THIS ISSUE REVOLVES AROUND CUSTOMER NOTIFICATIONS. THE EXTENDED WARRANTY TIME IS 7 YEARS OR 90,000 MILES. MAZDA MAILED OUT A SINGLE LETTER TO OWNERS. MAZDA STIPULATED THAT THE EXTENSION WAS TRANSFERABLE, HOWEVER THEY MADE NO EFFORT TO NOTIFY ANY OF THE NEXT OWNERS, NOT A LINK ON THEIR WEBSITE EVEN. THIS MEANS THAT OWNERS WHO DID NOT GET NOTIFIED WILL NOT KNOW OF THIS ISSUE AND MAY SPEND ABOUT $600-800 TO FIX THE ISSUE EVEN THOUGH IT IS COVERED (OUTSIDE A DEALER). DUE TO THIS BEING A SAFETY ISSUE WITH BRAKES NOT PERFORMING AS EXPECTED DURING NORMAL USE, THIS SHOULD HAVE BEEN A RECALL. ANY SIGNIFICANT LOSS OF BRAKING POWER DURING NORMAL USE WILL CAUSE ANY NORMAL HUMAN TO PANIC. THE NHTSA ISSUED THIS WHILE THINKING AS ENGINEERS, NOT TAKING INTO ACCOUNT HOW THE HUMAN FEELS BEHIND THE WHEEL OF A CAR THAT IS NOT STOPPING. THERE ARE MULTIPLE REPORTS OF PEOPLE NEARLY GETTING INTO ACCIDENTS DUE TO THIS AT HTTPS://WWW.CARCOMPLAINTS.COM/MAZDA/CX-9/2012/BRAKES/BRAKE_POWER_BOOST_UNIT_FAILURE.SHTML AND OTHER SITES AROUND THE INTERNET. WILL IT TAKE INJURY OR DEATH FOR THE NHTSA TO ACT? MY OWN CX-9 STARTED HAVING ISSUES, AND WHEN I TOOK IT IN, THE DEALER STATED THE COST, AND DID NOT EVEN MENTION COVERAGE. I HAD TO LOOK IT UP. MOST PEOPLE WOULD NOT HAVE. MY CAR IS 2,500 MILES OUT OF THE EXTENSION AND MAZDA WOULD NOT COVER IT. THIS IS RIDICULOUS. IF I DIDN'T HAVE THE MONEY TO FIX IT, AND GOT KILLED, WOULD MAZDA BE FORCED TO RECALL?

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.

HELLO! THIS MORNING ON 19 DECEMBER 2017, MY WIFE WAS DRIVING IN A CITY STREET GETTING READY TO CROSS A MAJOR INTERSECTION. THE LIGHT TURNED YELLOW AND SHE BEGAN TO BRAKE. AT FIRST THEY FELT NORMAL, BUT THEN THE PEDAL WENT DOWN AND THE BRAKES FELT REALLY HARD AND THE HISSING STARTED, ALMOST RUNNING INTO THE BACK OF THE CAR IN FRONT OF HER. SHE PULLED OVER AND CALLED ME. WHEN I ARRIVED, I COULD HEAR A HISSING SOUND AS IF AIR WAS LEAKING FROM SOMEWHERE NEAR THE BRAKE BOOSTER. I AM AN AIR FORCE AIRCRAFT MECHANIC AND HAVE BEEN WORKING ON MY OWN CARS FOR OVER 40 YEARS. I SEARCHED ALL OVER THINKING THAT A HOSE MIGHT HAVE TORN OR PULLED OUT OF THE CHECK VALVE, BUT I COULD NOT SEE ANYTHING OBVIOUS. THE BRAKE FLUID LEVEL WAS FINE, SO I DROVE THE CAR HOME AND BEGAN TO SEARCH THE INTERNET. I FOUND THIS WEBSITE: HTTP://WWW.MAZDAPROBLEMS.COM/TRENDS/BRAKE-BOOSTER-FAILURE/ AND FOUND OUT THAT MAZDA HAVE KNOWN ABOUT THE ISSUE FOR YEARS. I'M REALLY UPSET THAT THEY WOULD NOT MAKE A RECALL ON SOMETHING LIKE THIS, SINCE IT AFFECTS BRAKE RELIABILITY AND COULD CAUSE AN ACCIDENT, INJURY OR DEATH!!! I'VE CONTACTED THE DEALERSHIP: HTTP://WWW.ELDORADOMAZDA.COM/ TO VERIFY IF IT WOULD BE COVERED, AND THEY TOLD ME THAT IT WAS NOT. WHEN I INQUIRED ABOUT WHY WEREN'T OWNERS NOTIFIED OF THIS POSSIBLY LETHAL SITUATION, THEY COULD NOT PROVIDE AN INTELLIGENT ANSWER, OTHER THAN YOUR CAR IS TOO OLD AND IT HAS TOO MANY MILES. OUR VEHICLE BARELY HAS 92K MILES ON IT, AN AVERAGE OF 13K PER YEAR. THEY STILL TOLD ME THAT THEY WOULD FIX IT, BUT THAT I'D HAVE TO PAY FOR IT . THIS SITUATION IS ABSURD AND NEGLIGENT AND I FEEL THAT ANYTHING TO DO WITH BRAKES AND THEIR PERFORMANCE OR LACK THERE OFF SHOULD BE A SAFETY RECALL AND OWNERS SHOULD NOT HAVE TO FIND OUT THE HARD WAY LIKE DAYS BEFORE CHRISTMAS OR AFTER AN ACCIDENT!!! PLEASE, HELP US! :) HOPE YOU HAVE A MERRY CHRISTMAS!

TAKATA RECALL I HAVE BEEN PROMISED A REMEDY AND NOTHING HAD HAPPENED YET. I WAS EVEN ASKED TO GET IN FOR A MAINTENANCE AND THEY'VE TOLD ME (2CE THAT DAY) WERE GOING TO CHANGE THE PART BUT NOTHING HAD HAPPENED YET. THIS IS UNACCEPTABLE.

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.

WHEN PRESSING THE BRAKE PEDAL, IT GETS HARD TO PUSH LIKE PRESSURE IS BUILT UP AND YOU CAN'T STOP. WHEN YOU ARE ABLE TO DEPRESS THE BRAKE PEDAL FULLY TO COME TO A COMPLETE STOP, YOU HEAR A HISSING SOUND AS IF AIR WAS LETTING AIR OUT OF THE TIRES. THE RESPONSE FOR SLOWING TO A STOP [WAS] MUCH LONGER AND UNLESS YOU PRESS THE PEDAL ALL THE WAY TO THE FLOOR, THE VEHICLE ROLLS. IT IS UNSAFE TO DRIVE

MY VEHICLE IS AT ABOUT 87000 MILES, THE BREAKS STARTED MALFUNCTIONING WHILE DRIVING ON THE HIGHWAY TEXAS 35 I HAVE TO PRESS HARD ON THE PEDALS IN ORDER FOR THE CAR TO STOP[ I DO HEAR KIND A LIKE A ZIZZLE WHEN I PRESS ON THE BREAKS BUT EVEN IF I PRESS HARD THE PEDAL TO STOP IT STILL KEEPS GOING FOR ABOUT 3 TO 4 FEET.

UPON STOPPING, BRAKE PEDAL BECAME HARD TO DEPRESS AND CAR WOULD NOT BRAKE EFFECTIVELY. BRAKING ACTION BECAME DEGRADED, TIME FRAME WAS ONE DAY. IT WAS INTERMITTENT, BUT WOULD NOT STOP EFFECTIVELY CREATING A HAZARD. UNABLE TO JUDGE STOPPING DISTANCE DUE TO BRAKE DEGRADATION. TOOK TO MECHANIC WHO REPLACED BRAKE BOOSTER, SAID MOST LIKELY A VACUUM ISSUE. SAID THIS IS A RECALL ITEM ON SAME PART FOR FORD ESCAPE 2010 AND LINCOLN MKZ. FORD OWNS MOST OF MAZDA AND THE CX-9 USES FORD MADE PARTS. UPON RESEARCH, MAZDA AND NHTSA BOTH KNOW OF THE ISSUE, BUT HAVE NOT ISSUED A RECALL NOTICE. FORD HAS WARRANTIED THE SAME PART FOR 150,000 MILES, MAZDA HAS NOT ISSUED RECALL FOR SAME PART WITH SAME PROBLEM AND RISK. UPON RESEARCH OF ONLINE BOARDS REGARDING THE SAME PROBLEM, THERE HAVE BEEN SEVERAL REPAIRS BY MAZDA OWNERS FOR THE SAME PROBLEM. THIS FAILURE ON MY CAR IS AT 98,000. WITH THE TAKATA AIRBAG RECALL, AND NOT BEING ABLE TO GET REPLACED AND THE BRAKE BOOSTER PROBLEM, PRESENTS SIGNIFICANT HAZARD TO MAZDA CX-9 OWNERS FOR RISK OF REAR END COLLISIONS DUE TO BRAKE BOOSTER FAILURE AND TAKATA AIRBAG DEPLOYMENT POTENTIALLY CAUSING SERIOUS HARM OR DEATH TO THE DRIVER AND PASSENGER. I AM WANTING NHTSA TO MOVE FORWARD PAST THE MONITORING PHASE AND ASK FOR A RECALL OR WARRANTY OF THE VACUUM BOOSTER FAILURE AT HIGHER MILEAGE AS FORD HAS ALREADY DONE THE SAME FOR THEIR VEHICLES FOR THE SAME PART.
