TOOK MY CAR TO DEALER 2-3 TIMES FOR THE BRAKES, WAY BEFORE MY WARRANTY WAS ANY WHERE NEAR EXPIRING, BECAUSE I KEPT HEARING A GRINDING SOUND. THEY KEPT TELLING ME NOTHING WAS WRONG, THAT MY BRAKES HAD SOME GRAVEL ON THEM AND THEY JUST CLEANED THEM. I DON'T TRAVEL ON DIRT ROADS OR ANYTHING, CITY ROADS/HIGHWAYS. NO OUT OF TOWN TRAVEL AT ALL, ACTUAL ONLY IN TOWN TRAVEL, HOME/WORK. MY 2ND CONCERN IS, WHILE DRIVING SOMETIMES MY SPEED SEEMS TO SHIFT, AS IF THE GEARS ARE SHIFTING. 3RD CONCERN IS, I RECEIVED A RECALL NOTICE, DON'T RECALL WHAT IT WAS ABOUT BUT I TOOK IT TO THE DEALERSHIP AND I WAS TOLD THEY DONE THAT WORK LAST TIME I CAME IN BUT I DON'T BELIEVE IT WAS DONE, SINCE THEY HAVEN'T BEEN HONEST WITH ME BEFORE. THEY DIDN'T EVEN LOOK AT THE LETTER. IF I RECALL CORRECTLY BRAKE COMPLAINTS/ SERVICE STARTED 2011 OR 2012 TO 2014....

VEHICLE WAS PARKED. THE TAILGATE WAS OPENED MANUALLY. I WAS MOVING ITEMS AROUND IN THE TRUNK TO MAKE ROOM FOR NEW PURCHASES. MY HUSBAND DID NOT SEE THAT I WAS MOVING ITEMS IN THE TRUNK. HE APPROACHED THE DRIVERS SIDE OF THE VEHICLE AND PRESSED THE POWER TAILGATE BUTTON INSIDE THE VEHICLE AND THE TAILGATE BEGAN TO CLOSE. IT MADE CONTACT WITH THE BACK OF MY NECK AND PUSHED MY FACE DOWN INTO THE FLOOR BOARD. THE SENSORS DID NOT WORK. WHEN THE TAILGATE MADE CONTACT WITH ME IT PUSHED DOWN HARDER AND FASTER INSTEAD OF GOING BACK UP TO OPEN. THIS CAUSED A SERIOUS INJURY TO MY NECK. SPECIFICALLY CERVICAL 5-7 HAD TO BE SURGICALLY FUSED WITH A TITANIUM PLATE AND SCREWS, AND MY SPINAL CORD HAD TO BE DECOMPRESSED AS THE DISCS HAD COMPRESSED MY SPINAL CORD AND COULD HAVE CAUSED COMPLETE PARALYSIS FROM MY NECK DOWN.

MY CAR HAD UNEXPECTED ACCELERATIONS 3 DIFFERENT TIMES. MY BRAKES WOULD NOT STOP MY CAR. I HAD A TEAR IN MY KNEE ON THE LAST INCIDENT IN MARCH 2012. MY MEDICAL BILLS WERE AROUND $5,000. MAZDA KEPT MY CAR AND GAVE ME A RENTAL. BUT SAID THEY COULD FIND NOTHING. I SOLD THE CAR. I KNOW THIS DEALERSHIP HAD ANOTHER MAZDA DO THE SAME THING AS MY CAR. THEY TOLD ME MAZDA WAS AWARE THERE WAS A PROBLEM. I HOPE SOMETHING IS DONE. I WASN'T KILLED BECAUSE I WAS ABLE TO GET TO THE GRASSY AREAS ALL 3 TIMES. BLOWING MY HORN AS A WARNING TO OTHER DRIVERS. I BELIEVE MY OLD CAR WAS TAKEN TO AN AUCTION BY MAZDA. AND THAT WAS A DANGEROUS VEHICLE. I WISH MORE PEOPLE WOULD REPORT IT. I HAD ANOTHER MAN TELL ME IT HAPPENED TO HIM BUT HE DIDN'T REPORT IT TO ANY ONE ELSE ACCEPT THE DEALER. THE DEALER I USE MAZDA IN VIRGINIA BEACH. THEY HAVE SERVICED OTHER MAZDA CX 9'S WITH THIS ISSUE. THEY PUT A BAND AID ON IT. THEY CHANGED THE THROTTLE IN MY NEW CAR WHEN IT FIRST HAPPENED. THAT DID NOT WORK. *TR

I WAS DRIVING AROUND A SHARP BEND IN THE ROAD. I PUSHED DOWN ON THE BRAKE PEDDLE TO SLOW DOWN AND THE CAR KEPT ACCELERATING AT THE SAME SPEED. THE CAR NEVER SLOWED DOWN AND I HAD TO TAKE THE CORNER AT A UNSAFE SPEED. I DROVE TO THE NEXT STREET AND TESTED THE BRAKES AND THEY WORKED FINE? VERY SCARY INCIDENT. *TR

WHILE DRIVING MY 2010 MAZDA CX-9 APPROXIMATELY 65MPH ON INTERSTATE 270S IN MARYLAND, I PRESSED THE GAS PEDAL TO ACCELERATE IN AN ATTEMPT TO PASS SEVERAL VEHICLES WHO WERE TRAVELING IN THE RIGHT HAND LANE. ONCE I FELT THAT I HAD ENOUGH ADDITIONAL SPEED TO SUCCESSFULLY PASS THE VEHICLES, I RELEASED THE GAS PEDAL AND NOTED THAT THE CAR CONTINUED TO ACCELERATE. I ATTEMPTED TO APPLY MY BRAKES, BUT THEY WOULD NOT SLOW THE VEHICLE. AFTER SEVERAL UNSUCCESSFUL ATTEMPTS TO APPLY MY BRAKES, I SEARCHED FOR A SAFE PLACE TO CONTINUE TRAVELING AS MY VEHICLE CONTINUED TO ACCELERATE, NOTING I WOULD NEED TO SHIFT INTO NEUTRAL AND MOVE INTO THE MEDIAN. LUCKILY, AFTER NUMEROUS REPEATED ATTEMPTS, MY BRAKES FINALLY ENGAGED AND SLOWED THE VEHICLE. I FEEL THIS IS A MANUFACTURER'S DEFECT THAT COULD ULTIMATELY LEAD TO A FATALITY. I AM TOO SCARED TO DRIVE THE VEHICLE AT THIS POINT IN TIME. *TR

I PURCHASED A NEW MAZDA CX 9 IN THE FALL OF 2010. AFTER A FEW MONTHS, I NOTICED THE TRACTION CONTROL "TCS OFF" BUTTON ILLUMINATED WHILE DRIVING UP A PAVED INCLINE. AFTER TURNING OFF THE ENGINE AND RESTARTING, THE TCS-OFF BUTTON SHUT OFF. THIS HAPPENED A COUPLE OF TIMES BEFORE MY FIRST SERVICING. I MENTIONED THE ISSUE TO THE MAZDA DEALERSHIP WHEN I WENT IN FOR REGULAR SERVICING. THEY CHECKED IT AND SAID THEY FOUND NO PROBLEM WITH IT. YET THE PROBLEM CONTINUED SPORADICALLY. THE TCS-OFF LIGHT OCCASIONALLY ILLUMINATES ON INCLINED ROADS, IN RAIN OR SNOW, WHEN DRIVING FROM A PAVED TO AN UNPAVED ROAD (OR VICE VERSA). STILL THE DEALERSHIP FOUND NO PROBLEMS DURING SERVICING. NOW IN THE THIRD YEAR OF DRIVING, I MENTIONED THE TCS AGAIN TO THE DEALERSHIP, AND THIS TIME THEY SAID, OH YES, IT IS A PROBLEM.. MAZDA RELEASED A BULLETIN ABOUT IT, SAYING THE TCS NEEDS TO BE REPAIRED FOR $340, AND THE CAR SHOULDN'T BE DRIVEN UNTIL IT'S REPAIRED. YET THIS IS THE CONDITION I'VE ALWAYS DRIVEN IT IN! AND OF COURSE, NOW MY WARRANTY HAS EXPIRED, AND I'M LIABLE FOR REPAIRS EVEN THOUGH THIS PROBLEM EXISTED RIGHT FROM THE VERY BEGINNING. THE DEALERSHIP HAS SAID THEY'D PUT IN A CALL, AND PERHAPS MAZDA WILL COVER AT LEAST PART OF THE COST. IF IT HAD BEEN REPAIRED UNDER WARRANTY, I WOULDN'T BE LIABLE FOR THE REPAIR AND I WOULDN'T HAVE TO PAY FOR THE RENTAL CAR WHILE I'M WAITING. I'LL SEE HOW IT PANS OUT. VERY FRUSTRATING. *TR

THE FIRST TIME I EXPERIENCED THIS TERRIFYING ORDEAL WAS IN NOVEMBER OF 2011. SINCE THEN, I HAVE HAD IT HAPPEN TWO MORE TIMES. THE CAR ACCELERATES OF UP TO SPEEDS OF 90 MPH WITHOUT WARNING . ALL 3 INCIDENTS HAVE HAPPENED ON THE HIGHWAY. THE BRAKES SLOW IT DOWN, BUT DO NOT STOP IT. ALL 3 TIMES, I'VE BEEN LUCKY ENOUGH TO GET THE CAR TO THE SHOULDER AND RIDE DOWN THE MEDIAN , PUSHING THE EMERGENCY BREAK IN AND AT ONE POINT PUSHING IT INTO PARK. MAZDA KNOWS ABOUT THIS. THEREFORE THEY ARE LIABLE. MAZDA WILL TELL YOU IT'S A THROTTLE PROBLEM, THEY WILL TELL YOU THERE IS NO WEAR ON THE BRAKES....WELL, THAT'S BECAUSE WHEN THE CAR DOES THIS UNEXPECTED ACCELERATION, THE BRAKES ONLY GO PART WAY..ALMOST LIKE PUSHING AGAINST AIR. THIS IS A SERIOUS PROBLEM WITH THE COMPUTER AND POSSIBLY THROTTLE COMBINED. MY CAR IS NOT FIXED, IT'S ALSO DOING OTHER STUFF. MAZDA WANTS ME TO KEEP THIS CAR AND DRIVE IT. THEY ARE GIANTS, SO THE LITTLE PERSON LIKE ME DOES NOT MATTER TO THEM IT'S THE $$$$. BUT WHEN SOMEONE DIES, IT WILL COST THEM $$$$$$$$$$. THERE NEEDS TO BE A RECALL. I HOPE MORE PEOPLE COME FORWARD. IT COULD SAVE YOUR LIFE OR/AND SOMEONE YOU LOVE AND OTHER DRIVERS ON THE ROAD WHO ARE IN DANGER OF YOU HURTING/KILLING THEM. MY MAZDA DEALERSHIP HAVE WONDERFUL PEOPLE WHO WORK THERE. THEY ARE VERY UNHAPPY WITH MAZDA NOT TAKING CARE OF THIS PROBLEM. I WANT TO MAKE THIS CLEAR, IT'S MAZDA CORP THAT IS AWARE AND DOING NOTHING AND THEY HOLD THE MAZDA DEALERS HOSTAGE. *TR

WAS DRIVING ON I-495E IN MARYLAND BETWEEN EXITS 28 AND 29. CHANGED LANES AND PUT FOOT DOWN ON GAS PEDAL TO ACCELERATE. SUDDENLY FELT LIKE GAS PEDAL WAS STUCK AND THAT BRAKING COULD ONLY SLOW BUT NOT STOP ACCELERATION. MOVED OVER A FEW LANES TO RIGHT SHOULDER AND AFTER CONTINUED FAILURE OF BRAKES TO STOP ACCELERATION (AND CONSIDERABLE ENGINE TORQUE) BEGAN TO APPLY EMERGENCY BRAKE. SLOWED ACCELERATION FURTHER BUT STILL COULD NOT BRING CAR TO A FULL STOP. FINALLY PUT CAR INTO NEUTRAL AND CAME TO A STOP. HAD TOWED TO NEAREST MAZDA DEALER, YET AFTER SEVERAL DAYS OF TESTING THEY FOUND NOTHING WRONG WITH CAR AND COULD NOT REPLICATE. CLAIMED MANUFACTURER HAD NO RECORD OF SIMILAR PROBLEMS WITH THIS MODEL. ONLY THING THEY COULD THINK OF WAS THAT ALL-WEATHER FLOOR MAT MIGHT HAVE SLID OVER PEDAL AND KEPT IT DEPRESSED. *TR
