WHEN ACCELERATING AFTER DRIVING FOR A FEW MINUTES MAYBE 10-15 AFTER THE VEHICLE HAS HAD TIME TO WARM UP, AS I AM APPLYING PRESSURE TO THE GAS PEDAL AND IT IS SHIFTING INTO GEARS (USUALLY INTO GEARS 3,4, & 5) THE VEHICLE IS SHOWING THAT IT IS INTO THE NEXT GEAR BUT YOU FEEL IT SHIFT AFTER THE FACT SO IT IS DELAYED AND AS ACCELERATING IT FEELS AS THOUGH IT IS LAGGING AND TRYING TO SHIFT BUT CAN'T FULLY RIGHT AWAY. I AM ONLY SUBMITTING THIS COMPLAINT BECAUSE I KNOW A COUPLE OTHERS WITH THIS MAKE OF VEHICLE BUT DIFFERENT YEARS AND THEY STATED THEY HAVE THE SAME ISSUE WITH THEIR VEHICLE AS WELL
ONE DAY, MY KEYLESS DON STOPPED WORKING. THE NEXT DAY THE DOOR KEPT LOCKING WHILE I WAS DRIVING ALMOST EVERY TIME I TURNED THE STEERING WHEEL. THEN THE DRIVERS DOOR WOULDN'T UNLOCK, WHEN I MANUALLY UNLOCKED THE DOOR IT WAS HARD TO DO. I LUCKILY HAD THE WINDOWS ROLLED DOWN, GOT OUT THE VEHICLE AND AS SOON AS I SHUT THE DOOR I HEAR THE DOOR LOCK AND MY TWO YEAR OLD WAS IN THE BACKSEAT! AGAIN LUCKILY I HAD THE WINDOWS ROLLED DOWN OTHERWISE SHE MIGHT'VE BEEN STUCK! THEN THE ALARM KEPT GOING OFF AND WOULDN'T TURN OFF UNTIL I UNHOOKED THE BATTERY. IMAGINE MY FRUSTRATION. I BROUGHT THE CAR TO A MAZDA DEALERSHIP WHO SAID IT WAS THE DOOR LATCH/ACTUATOR. UPON PAYING HEFTILY WHEN I PICKED UP MY CAR, THE CLICKING OF THE DOOR LOCKS HAD STOPPED BUT THE UNLOCK BUTTON STILL WOULDN'T WORK AND THE ALARM WAS ONCE AGAIN GOING OFF! NOW THE CAR IS STILL AT THE MAZDA DEALERSHIP AND HAD ITS BCM/BCU REPLACED FOR A SUPPOSED 'FIX', I'M SUPPOSE TO PICK IT UP TOMORROW. SO I GUESS WE'LL SEE. THE APPARENT PROBLEM FROM ALL OF THIS? MY CX9 HAS A SUNROOF, WHICH MAZDA KNOWS THESE VEHICLES DON'T DRAIN PROPERLY WHICH CAUSES WATER TO GO TO THE BCM SHORTING IT OUT! THIS IS INEXCUSABLE AND COULD VERY WELL COST SOMEONE'S CHILD THEIR LIFE BECAUSE OF THE DOORS CONSTANT LOCKING AND UNABLE TO UNLOCK SOMETIMES MANUALLY. THE DEALERSHIP HAS SEEN IT ON MORE THAN ONE OCCASION AND MAZDA COMPANY HAS EVEN ADMITTED THIS FAULT! SO WHY IS THERE NO RECALL?!
WE BOUGHT OUR CAR ON A DEALER IN MESA, IT WAS STATIONARY. AFTER WE BOUGHT IT WE NOTICED LOCKS MOVING ON THEIR OWN WINDOWS ROLLING DOWN SO DID THE MOON ROOF. WHEN WE TURN OFF THE ENGINE THE A/C TURNS ON EVEN THOUGH THE CAR IS TURNED OFF. THE CAR LOCKS ITSELF LEAVING US OUTSIDE. WE HAD PROBLEMS WITH THE TIRES THEY KEEP LOOSING UP MAKING THE CAR VIBRATE AND MAKING SOUNDS LIKE BANGING ON THE TIRES

TL* THE CONTACT OWNS A 2008 MAZDA CX-9. THE CONTACT STATED THAT THE VEHICLE WAS UNABLE TO START. THE VEHICLE WAS TOWED TO THE DEALER WHERE THE FAILURE WAS UNABLE TO BE DETERMINED.

RETURNED TO VEHICLE AFTER WORK (5PM) AND SAW THAT BOTH SIDE MIRRORS WERE DAMAGED. A CLOSER LOOK REVEALED THAT THE PAINTED PORTION TO BOTH SIDE MIRROR HOUSING UNITS HAD MELTED. IT APPEARED THE PLASTIC HAD MELTED FROM INTERNAL HEAT. THERE WERE NO BURN MARKS ON THE OUTER PORTION OF THE UNIT. THE PLASTIC HAD SHRUNK TO A SHRIVELED AND WRINKLED APPEARANCE. BROUGHT THE VEHICLE TO A MAZDA DEALER (ESCONDIDO, CALIFORNIA). THE VEHICLE WAS INSPECTED AND NOTHING WAS FOUND TO BE WRONG. I WAS TOLD THERE WAS NO ELECTRICAL PROBLEM AND THE MELTED SIDE MIRROR UNITS WERE MELTED FROM THE SUN. I DO NOT LIVE IN ARIZONA, NEW MEXICO, OR SOUTHERN NEVADA WHERE TEMPERATURES REACH ABOVE 105 DEGREES CONSISTENTLY. TEMPERATURES TYPICALLY REACH 80-95 DEGREES. *TR
2008 MAZDA CX9 SMART KEY, AFTER REPROGRAMMING ($350) NEW FOBS ($100 EACH) AND NUMEROUS BATTERY REPLACING THE SMART KEY STILL WILL NOT FUNCTION AS PROMISED, WIRELESSLY UNLOCKING, LOCKING AND STARTING THE VEHICLE. HERE IS ONLY ONE KEY HOLE ON THE VEHICLE, WHICH CASES HE OWNER/ DRIVER/ USER TO CONSTANTLY WALK AROUND THE VEHICLE TO LOCK/ UNLOCK AND/OR START THE CAR. IT ALSO GREATLY INCREASES THE RISK OF LOOSING THE ONLY HARD COPY OF THE KEY COSTING ANOTHER $350 IN PROGRAMMING AND CUTTING. *TR
THERE HAVE BEEN A MULTITUDE OF PROBLEMS ON THE VEHICLE (TWO SETS OF BRAKES, TIEROD, ELECTRICAL OVERHAUL VACUUM HOSES...) THE MAJOR ISSUE HAS BEEN OIL LEAKING. THIS PAST SUMMER (2011) THERE WAS AN OIL LEAK. THE DEALER HAD THE CAR FOR SEVERAL DAYS BEFORE DIAGNOSING THAT IT WAS THE REAR MAIN SEAL. THE SEAL WAS REPLACED (CAR WAS AT DEALER FOR NEARLY TWO WEEKS.) THIS FALL (2011) OIL WAS STILL LEAKING. AFTER SEVERAL DAYS THE DEALER CONTACTED MAZDA CORPORATE AND THEY SUGGESTED REPLACING THE TRANSMISSION, CLAIMING IT WAS NOT UNCOMMON. THE DEALER REPLACED THE TRANSMISSION. WINTER/SPRING 2012 OIL STILL LEAKING, CAR IS CURRENTLY AT THE DEALER - CLAIMING IT IS THE REAR MAIN SEAL. AGAIN? WOULDN'T THAT HAVE BEEN REPLACED WITH THE NEW TRANSMISSION? *TR
