ENGINE OVERHEATED WHILE DRIVING IN A STRAIGHT LINE IN TRAFFIC AT LOW SPEED WITH TEMPERATURE IN THE 80'S. THE ENGINE BLOCK CRACKED AS A RESULT. THE ENGINE AND THE COMPLETE COOLING FAN ASSEMBLY HAD TO BE REPLACED. THE ENGINE TEMPERATURE HAD RISEN HIGH ON SEVERAL OCCASIONS BEFORE THIS, WHILE IDLING, DRIVING AT LOW SPEEDS, AND DRIVING AT MODERATE AND HIGHWAY SPEEDS, TEMPERATURES RANGING FROM 50'S TO 90'S. WHEN THE OVERHEATING OCCURRED THE AIR CONDITIONING ALSO FAILED TO FUNCTION PROPERLY. I HAD COMPLAINED TO THE DEALERSHIP ABOUT THIS ISSUE AND THEY CLAIMED IT WAS A FUSE. THEY REPLACED THE FUSE, BUT IT DID NOT RESOLVE THE ISSUE. *TR

WAS DRIVING VEHICLE AT 45 MILE PER HOUR. SUDDENLY NOTICED STEERING WHEEL WAS OFF CENTER. I DID NOT HIT A POTHOLE OR ANY OTHER OBSTRUCTIONS ON THE ROAD. STEERING BECAME VERY LOOSE AND VEHICLE HARD TO STEER. WHEN BRAKING THE VEHICLE STARTED TO MAKE SQUEALING SOUND AND PULLED TO ONE SIDE. SUSPENSION BECAME VERY HARSH EVEN ON GOOD SURFACE ROAD.. THIS IS A CATASTROPHIC FAILURE WITH NO WARNING. FORTUNATELY WAS ABLE TO GET VEHICLE TO AUTO REPAIR CENTER WITHOUT GETTING INTO ACCIDENT. AUTO REPAIR FACILITY EXAMINED VEHICLE AND SHOWED ME THAT ENGINE CRADLE - SUBFRAME HAD RUSTED THOUGHT AND BROKE. THIS CAUSED THE ENGINE TO GO OFF CENTER WHICH CAUSED THE BRAKING, STEERING, AND SUSPENSION ISSUES. AUTO REPAIR FACILITY TOLD ME THE VEHICLE WAS NOT SAFE TO DRIVE AND MADE ME SIGN A WAIVER TO RELEASE THE VEHICLE.

I WENT FOR AN OIL CHANGE AND FOUND OUT THAT THE FRAME THAT HOLDS THE ENGINE IN PLACE WAS COMPLETELY ROTTED OUT AND THAT MY ENGINE COULD FALL OUT AT ANY GIVEN TIME. ALSO, BECAUSE OF THE ROT, THE ROD THAT SHOULD BE ATTACHED TO THE STEERING WAS NOT ATTACHED BECAUSE THE BOLTS HAD NOTHING TO ADHERE TO. THIS COULD HAVE RESULTED IN ME DRIVING WITH MY DAUGHTER AND LOSING MY STEERING AND POSSIBLY GETTING IN A FATAL ACCIDENT. THE CAR IS IN THE SHOP AS IT IS NOT ABLE TO BE DRIVEN PER MY MECHANIC FOR SAFETY REASONS AS WELL AS FAILING INSPECTION FRO THIS. PLEASE CONTACT ME AS SOON AS POSSIBLE AS I DO NOT HAVE ANY TRANSPORTATION AND I WORK FULL TIME. I CAN BE REACHED AT [XXX]. OR MY MECHANIC AT HOMETOWNE AUTO, [XXX].

I BOUGHT MY MAZDA 6, YEAR 2009, BRAND NEW FROM A MAZDA DEALER IN VIRGINIA. SOME TIME AGO, WHILE I WAS DRIVING IT AT APPROXIMATELY. 30 MPH IN HEAVY TRAFFIC ON ONE OF THE MAIN ROADS, I THEN TURNED ON THE LEFT TURN SIGNAL AS I NEEDED TO MAKE A LEFT TURN AT THE VERY NEXT LIGHT. SUDDENLY, THE ENGINE DIED COMPLETELY AND THE CAR STOPPED IN THE MIDDLE OF THE TRAFFIC. LUCKILY I WAS NOT HIT BY THE DRIVERS BEHIND ME. I WAS ABLE TO PUT THE GEAR IN PARK, START THE ENGINE AGAIN AND DRIVE THE CAR HOME. I THEN CALLED THE MAZDA DEALER (WHERE I HAD BOUGHT THE CAR) AND I IMMEDIATELY MADE AN APPOINTMENT TO HAVE THE CAR CHECKED. TO MY GREATEST DISAPPOINTMENT, THE MAZDA DEALERSHIP TOLD ME THERE WAS NOTHING WRONG WITH MY CAR AND THEY COULD NOT FIND THE CAUSE OF THE PROBLEM I HAD ON THE ROAD, WHEN THE ENGINE DIED WHILE I WAS DRIVING MY CAR. A FEW MONTHS LATER A SIMILAR PROBLEM HAPPENED AGAIN AND THE MAZDA DEALER COULD NOT FIND ANY PROBLEM WITH IT AT THAT TIME EITHER. NOW MAZDA HAS A RECALL FOR MAZDA 6, 2010-2012 ONLY, BUT IT'S FOR THE SAME PROBLEM WITH THE SPIDER'S WEBS AND POSSIBLE RISK OF CRACKS IN THE FUEL TANK, WITH A RISK OF A FIRE. I'M CONCERNED THE YEAR 2009 IS NOT INCLUDED IN THE RECALL SINCE THE SAME PROBLEM APPEARED IN THE EARLIER RECALL. *TR

I HEARD CHIRPING NOISE FROM THE CAR AND TOOK IT TO A DEALER WHO WASN'T ABLE TO REPRODUCE THE NOISE BUT THE NOISE CAME BACK AND WITH IN THE NEXT 10 DAYS IT GOT WORSE. THE DEALER TOLD THAT THERE WAS A LEAKAGE FROM EXHAUST DONUT AND EXHAUST HEAT SHIELD HAD TO BE FIXED. I GOT THEM FIXED AND AFTER 3 DAYS AND LESS THAN 100 MILES I HEAR THE CHIRPING NOISE AGAIN AND THIS TIME IT IS LOUDER. I CAN HEAR IT EVEN WHEN THE CAR IS PARKED. *TR

I WAS DRIVING WITH MY AC ON IN MY 2009 MAZDA 6 AND THE CAR BEGAN TO OVERHEAT AND THE AC GOT HOT. I HAD TO PULL OVER WITH MY INFANT IN THE CAR INTO THE NEAREST PARKING LOT. THE CAR WAS BROUGHT TO MAZDA AND THEY SAID THAT THE COOLING FAN FOR THE MOTOR AND THE AC WERE FAULTY, BUT SINCE THE CAR WAS 4,000 MILES OVER WARRANTY, THEY WOULD ONLY GIVE $200 TOWARD THE $907 JOB FOR THEIR FAULTY PART. I LOOKED IT UP AND THERE IS A TSB FOR THIS PART. NHTSA ITEM #10032548 . IF THERE ARE MANY OTHERS HAVING A PROBLEM WITH THIS FAULTY MANUFACTURED PART ON RELATIVELY NEW CARS I BELIEVE THERE SHOULD BE A RECALL. IT WAS THE HOTTEST DAY OF THE SUMMER HERE WHEN THE AC WENT AND MY CAR STARTED TO OVERHEAT WITH MY 6 MONTH OLD IN THE CAR. MY CAR ONLY HAS 40,000 MILES ON IT. *TR

MY 2009 MAZDA 6 I TOURING AT DURING DRIVING AT 20-25 MPH OR AT 50-80 MPH PRODUCES A SULFUR EMISSION FROM THE AIR VENTS INSIDE AS WELL AS FROM THE EXHAUST PIPES. THIS BEGAN WHEN THE ODOMETER WAS JUST OVER 300 MILES. EVEN THOUGH THIS CAR REQUIRES REGULAR UNLEADED OCTANE RATING 87 GAS, OCTANE RATING 92 HAS BEEN USED AS WELL AS GENERIC BRANDS OF GAS. SINCE SWITCHING BACK FROM OCTANE 92 GAS TO REGULAR UNLEADED OCTANE 87 GAS (AS ADVISED FROM THE METRO MAZDA DEALERSHIP IN MA) AND FROM THE GENERIC TO A MORE RECOGNIZED BRAND OF GAS (MOBILE), THE SULFUR EMISSION FROM THE AIR VENTS HAS BEEN GREATLY REDUCED TO BECOME A RARE OCCURRENCE, BUT IS STILL THERE, AS RECENT AS 10/22/09 ON THE HIGHWAY WITH ABOUT 4200 MILES ON THE ODOMETER. THE SULFUR EMISSION STILL COMES OUT FROM THE EXHAUST PIPES AND IS MOST NOTABLE IN THE GARAGE WHETHER THE CAR IS RUNNING OR NOT. THE SMELL IS STILL NOTICED WHEN OUTSIDE, RUNNING OR NOT, AND HAPPENS FREQUENTLY, ALMOST EVERY TIME THE CAR IS SHUT OFF. WHETHER DISTANCE IN TRAVEL IS SHORT OR LONG, THE EMISSION FROM BOTH AREAS REMAINS AND HAS BEEN ONGOING SINCE THE FIRST OCCURRENCE. *TR

I TOOK MY 2009 MAZDA6 TOURING EDITION IN TO GET MY FIRST OIL CHANGE. THE CAR WAS IN PERFECT CONDITION WITH ONLY 3,600 MILES. WHEN I RETURNED LATER TO PICK UP THE CAR I WAS TOLD THAT THERE WAS A SAFETY RECALL FOR THE DOOR LOCKS. I SAID OKAY SO WHAT NOW. THE JIM ELLIS SERVICE DEPARTMENT SAID WE WILL GIVE YOU A LOANER. I TURNED IN THE CAR ON SATURDAY I PICKED THE CAR UP ON TUESDAY AND DROVE IT HOME. WHEN I ARRIVED AT MY HOUSE I TRIED TO LOCK THE DOOR BY PUSHING THE BUTTON ON THE DRIVER SIDE. NOTHING HAPPENED SO I TRIED A FEW MORE TIMES. THE ONLY WAY TO LOCK THE DOOR WAS WITH THE KEY. I CALLED THE SERVICE DEPARTMENT THE NEXT MORNING AND THEY ASKED IF I COULD BRING THE CAR BACK FOR THEM TO TAKE A LOOK. I TOOK THE CAR BACK AND THEY STILL COULD NOT FIGURE OUT WHAT WAS WRONG. THEY AGAIN GAVE ME A LOANER CAR. THURSDAY EVENING I WAS TOLD THE CAR WAS FIXED. THEY SAID AN ENGINEER HAD LOOKED AT THE CAR AND IT WAS FIXED FOR SURE. WELL GUESS WHAT IT IS STILL NOT FIXED. NOW THEY ARE TELLING ME THAT THE BATTERY MUST HAVE BEEN RUN DOWN BECAUSE THE DOORS WERE LEFT OPEN. THURSDAY EVENING I AM HOME WITH MY LOANER FROM JIM ELLIS WONDERING IF I WILL EVER GET MY CAR BACK AND IF I DO GET IT BACK WILL IT REALLY BE FIXED. *TR
