2012 MAZDA CX-9 Complaints

TL* THE CONTACT OWNS 2012 MAZDA CX9. THE CONTACT STATED THE BRAKES WOULD HISS WHEN BEING DEPRESSED. THE CONTACT ALSO STATED THAT THERE WAS AN ABNORMAL INCREASE IN BRAKING DISTANCE AND TIME. THE VEHICLE WAS TAKEN TO THE DEALER FOR DIAGNOSIS, WHO STATED THAT THE BRAKE BOOSTER AND POSSIBLY THE MASTER CYLINDER WOULD NEED TO BE REPLACED. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOT ALERTED OF THE FAILURE. THE FAILURE MILEAGE WAS 35,000.

AT APPROXIMATELY 25,300 MILES, MY 2012 CX9 TOURING STARTED STALLING AT TRAFFIC LIGHTS. IT WAS SPORADIC, BUT APPEARED TO HAPPEN WHEN I USED MORE FORCE WHEN BRAKING. WITHIN DAYS I NOTICED A VERY DISTINCT HISSING SOUND WHILE BRAKING, MUCH LIKE AIR WAS LEAKING FROM MY TIRES. AT THIS POINT, BRAKING BECAME INCREASINGLY MORE DIFFICULT, AND THE DISTANCE REQUIRED TO STOP MY CAR WAS MUCH GREATER. I ALMOST HAD A COLLISION BECAUSE I DID NOT REALIZE I NEEDED TO BEGIN BRAKING SOONER IN ORDER TO STOP MY CAR AND I VEERED INTO A GRASSY MEDIAN TO AVOID THE ACCIDENT. IN ORDER TO STOP THE CAR I HAD TO APPLY BOTH FEET TO MY BRAKE PEDAL AND IT WAS NEARLY ON THE FLOOR. THE SERVICE ADVISOR SAID THIS WAS A SAFETY ISSUE AND FOUND THE "BRAKE BOOSTER FAILING INTERNALLY", AND IT WAS REPLACED. THE STALLING WAS DUE TO "VACUUM LEAK THROUGH BOOSTER". THERE WAS NO INDICATION THAT MY BRAKES HAD A PROBLEM; NO DASHBOARD MAINTEANCE LIGHTS WERE PRESENT. THIS IS A SERIOUS SAFETY ISSUE. I JUST READ ABOUT A CURRENT BRAKE BOOSTER FAILURE INVESTIGATION WITH 2010 AND 2011 MODEL YEARS, BUT 2012 NEEDS TO BE INCLUDED IN THIS INVESTIGATION AS WELL. *TR

THE BRAKE ASSIST BOOSTER ON THIS VEHICLE FAILED. THIS IS THE SAME ISSUE CITED IN A NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION INVESTIGATION OF THE 2010-2011 MAZDA CX9 VEHICLES. *TR

BRAKES NOT WORKING PROPERLY, REDUCED BRAKE EFFECTIVENESS, HARD PEDAL AND NOT STOPPING PROPERLY, AND A DEFINITE CONSTANT HISSING WHEN APPLYING THE BRAKE PEDAL. POSSIBLE MASTER CYLINDER ISSUE. MAZDA CX9, 2012. VERY SIMILAR TO COMPLAINTS AND ONGOING INVESTIGATION, EXCEPT FOR THIS IS A 2012. *TR

I AM UNSURE OF THE FIRST DATE OF OCCURRENCE, BUT THE FOLLOWING HAVE BEEN HAPPENING SINCE I PURCHASED THIS VEHICLE NEW WITH 12 MILES ON IT. AND THE DEALER CAN'T FIND ANYTHING WRONG WITH IT. 1. THE AC ALWAYS COMES ON. EVEN WHEN IT'S BELOW ZERO OUTSIDE. 2. IT FAILS TO GO WHEN PUSHING ON THE ACCELERATOR FREQUENTLY, AND ESPECIALLY IN REVERSE, FROM A STOPPED POSITION, UNTIL YOU REALLY PUSH HARD ON THE ACCELERATOR CAUSING IT JUMP. 3. LAST FRIDAY 2/21/2014 AS I WAS ON A RAMP MOVING FROM ONE INTERSTATE TO ANOTHER, THE ENGINE CONTINUED TO REV UP EVEN AFTER I LET OFF THE GAS, AND PUSHED THE BRAKE. THIS IS NOT THE FIRST OCCURRENCE OF THIS, IT'S ACTUALLY HAPPENED AT LEAST 10-12 TIMES. IT WAS DEFINITELY THE MOST SCARY, AS I THOUGHT I WAS GOING OVER THE SIDE OF THE RAMP OR INTO THE SEMI IN FRONT OF ME FOR A MINUTE OR SO. 4. THE BRAKES SQUEAK LOUDLY WHEN IT'S COLD. 5. THE BRAKES ARE EITHER REALLY SENSITIVE, OR YOU HAVE TO STOMP THEM TO GET THEM TO WORK, SO SINCE YOU DON'T KNOW WHICH IT'S GOING TO BE YOU'RE LIKELY TO JERK YOURSELF AND YOUR PASSENGERS AROUND A LOT. 6. THE VEHICLE PULLS TO ONE SIDE OR THE OTHER, WHICH WOULD SEEM TO INDICATE THAT AN ALIGNMENT IS NEEDED, HOWEVER, IT CAN'T PICK WHICH SIDE IT'S GOING TO GRAVITATE TOWARDS WHICH LEADS ME TO BELIEVE IT'S SOMETHING IN THE STEERING. *TR

AS I WAS DRIVING HOME, THE VEHICLE BEGAN TO SLOW DOWN AND SOON CAME TO A COMPLETE STOP, EVEN AS I CONTINUED TO PRESS THE ACCELERATOR PEDAL, ALL AS THE ENGINE CONTINUED TO RUN. AT THE SAME TIME, I NOTICED A BURNING OIL ODOR. THIS SUDDEN DECELERATION AND STOP OCCURRED IN THE MIDDLE LANE OF A MAJOR CHICAGO-AREA TOLL ROAD ON A COLD AND RAINY FRIDAY EVENING. A POLICE OFFICER WHO ARRIVED AT THE SCENE WAS UNABLE TO PUSH MY CAR OUT OF DANGER WITH HIS CAR. FORTUNATELY, THE CAR WAS TOWED AWAY TO A MAZDA DEALER BEFORE AN ACCIDENT OCCURRED. THE DEALERSHIP TECHNICIAN CONFIRMED THE PROBLEM AND FOUND THAT THE TRANSFER CASE HAD OVERHEATED, LOST ALL ITS FLUID, AND SEIZED. THE TRANSFER CASE WAS REPLACED UNDER WARRANTY. THE FAILURE OF THE TRANSFER CASE AND SUBSEQUENT SUDDEN DECELERATION PUT ME IN GRAVE DANGER, AND SUCH A FAILURE IS UNFORGIVABLE FOR SUCH A NEW VEHICLE. I FEEL THAT HAD THE TRAFFIC ON THE EVENING OF THE INCIDENT NOT BEEN AS HEAVY, AND THUS SLOW AS IT WAS, I VERY WELL MAY HAVE BEEN REAR-ENDED BY ANOTHER MOTORIST. I URGE THE NHTSA TO CLOSELY TRACK ANY OTHER INCIDENTS CONCERNING SEIZED TRANSFER CASES IN MAZDA CX-9S--THIS IS POTENTIALLY A VERY DANGEROUS DEFECT. *TR

TL* THE CONTACT OWNS A 2012 MAZDA CX-9. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 45 MPH, THE VEHICLE STALLED UNEXPECTEDLY. THE VEHICLE NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED. THE FAILURE MILEAGE WAS 35,000.

I HAVE A MAZDA 2012 THAT SPONTANEOUSLY STALLS WHILE DECELERATING. IT ALSO STALLS PREDICTABLY ON AN INCLINE. MAZDA CORPORATION HAS STATED "THE STALLING ON AN INCLINE IS A CHARACTERISTIC OF ALL CX-9 MODELS" AND ARE NOT WILLING TO FIX IT. THEY HAVE INFORMED ME THAT STALLING WHILE DECELERATING IN MY CAR HAS NOT BEEN ABLE TO BE RECREATED BY THEIR TECH SO THEY ARE DOING NOTHING ABOUT IT. I HAVE BEEN IN TWO NEAR MISS ACCIDENTS. THE CAR LOSES POWER STEERING AND BRAKING AND THE DRIVER HAS LITTLE TO NO CONTROL WHEN IT STALLS. PLEASE WATCH THIS VIDEO OF A BRAND NEW (LOANER FROM THE DEALER WHILE THEY LOOKED AT MY 2012 CX-9) 2013 CX-9 (125 MILES ON IT). THIS IS THE "CHARACTERISTIC" I AM REFERRING TO, PLEASE ADVISE FUTURE BUYERS OF THIS VERY UNSAFE "CHARACTERISTIC". WHEN IT STALLS IN MY DRIVEWAY, I CANNOT BRAKE "SHARPLY" OR EFFECTIVELY ENOUGH TO STOP THE CAR FROM DRIFTING INTO THE ROAD. HTTP://YOUTU.BE/PBZHVIEIHKC. *TR

INCIDENT -1 TRAVELING ABOUT 45 MPH DECELERATING TO MAKE A RIGHT TURN, THE CAR STALLS OUT LEAVING ME WITH NO CONTROL OF STEERING AND LITTLE ABILITY TO BRAKE. INCIDENT 2- MAKING RIGHT TURN (DECELERATING) CAR STALLS OUT LEAVING ME WITH NO STEERING AND LITTLE BRAKING CONTROL. INCIDENT 3- PULLED UP INTO DRIVEWAY ON SLOPE. PUT THE CAR IN REVERSE TO BACK OUT, CAR STALLED OUT LEAVING ME WITH VERY LITTLE ABILITY TO BRAKE. *TR

TL* THE CONTACT OWNS A 2012 MAZDA CX-9. THE CONTACT STATED THAT THE VEHICLE WOULD CONSUME EXCESSIVE OIL WITHOUT WARNING.

THE CONTACT STATED THAT THE TECHNICIAN MENTIONED THAT THE CONSUMPTION OF OIL WAS UNUSUAL AND COULD CAUSE THE ENGINE TO FAIL. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 900 AND THE CURRENT MILEAGE WAS 42,000. *TR
