2012 Mazda Mazda3 Engine Problems

WHEN I DRIVE DOWN THE ROAD.MY CAR SPEEDS UP AND I DON'T PRESS ON THE EXCILERATOR ANY HARDER. THE CARS IDOL GOES UP AND DOWN WHEN DRIVING AND AT PARK. THIS HAPPENS ON ALL TYPES OF ROAD WAYS. SOMETIMES IT SPEEDS UP ON ME SO FAST I HAVE TO HIT THE BRAKE WHILE DRIVING ON THE ROAD.

TL* THE CONTACT OWNS A 2012 MAZDA 3. THE CONTACT STATED THAT THE VEHICLE LEAKED FUEL. THE VEHICLE WAS TAKEN TO GREEN MAZDA (217-391-2400, LOCATED AT 3760 S 6TH ST, SPRINGFIELD, IL 62703) WHERE IT WAS DIAGNOSED THAT A CHARCOAL CANISTER FILTER WAS LOOSE AND NEEDED TO BE TIGHTENED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE WAS REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 142,000.

MASS AIRFLOW SENSOR FAILED AT 38,000 MILES CAUSING THE CAR TO STALL AND WOULDN'T RESTART.

THERE IS A PROBLEM WITH THE VARIABLE VALVE TIMING SYSTEM CAUSING REDUCED ACCELERATION PERFORMANCE. THE CHECK ENGINE LIGHT IS DISPLAYED. THIS PROBLEM IS EXACTLY THE SAME AS THE RECALL ON MAZDA3 VEHICLES MANUFACTURED BETWEEN JULY 2011 AND NOVEMBER 2011. THE CAR LOST ACCELERATION AND A VEHICLE BEHIND ME ALMOST REAR-ENDED MY VEHICLE. FOR SOME REASON MAZDA IS NOT RECOGNISING THE RECALL ON LATER MODELS AFFECTED BY THE SAME ISSUE. MAZDA RECALL REFERENCE IS 6511K. THE RECALL SHOULD BE EXPANDED TO COVER ADDITIONAL VINS

SQUEAKING NOISE FROM ENGINE COMPARTMENT. SOURCE APPEARS TO BE ENGINE MOUNT#4. NEEDS TO BE REPLACED AND GREASED. NOISE OCCURS IN MOTION, NO CORRELATION WITH TURNING OR SPEED.

I JUST GOT OFF WORK AND GOT IN MY CAR TO LEAVE. I TURNED ON THE CAR AND EVERYTHING SEEMED NORMAL. I PULLED OUT OF THE PARKING LOT AND AS SOON AS I PULLED UP TO THE LIGHT, WHICH WAS 1BLOCK AWAY, MY CAR SHUT OFF. I WAS JUST AT THE RED LIGHT WAITING THEN MY CAR TURNED OFF AND WOULD NOT TURN BACK ON. ALL THE POWER IN THE CAR WAS THERE BUT MY CAR WOULD JUST NOT TURN BACK ON, MY VEHICAL WAS BEING OPERATED IN THE AUTOMATIC POSITION.THIS WAS DANGEROUS BECAUSE IT WAS A FRIDAY AFTERNOON DURING THE 5 O'CLOCK TRAFFIC AND I HAD ALL THESE VEHICALS LINED UP BEHIND ME HONKING AND I HAD TO PUSH MY VEHICALS OFF TO THE SIDE AND CALL A TOW TRUCK. MY VEHICAL WAS LUCKILY ON THE CITY STREET.

UPON TURNING OFF THE ENGINE, THE EXHAUST FUME SMELLS LIKE ROTTEN EGG SMELL. THE MAZDA DEALER SAID THAT THERE IS NOTHING THEY CAN DO BECAUSE THERE IS NOT A RECALL ON THE CATALYTIC CONVERTER. THE MAZDA DEALER SUGGESTED USING ONLY SHELL GAS. THE MAZDA DEALER ALSO REPORTED THAT THERE IS NOT ENOUGH INCIDENTS YET FOR MAZDA TO RECALL THE CATALYTIC CONVERTER. *TR

THERE IS A ROTTEN EGG SMELL COMING FROM THE EXHAUST PIPE FROM THE CAR. MAZDA DEALER IS UNABLE TO RESOLVE THE PROBLEM WHEN I WENT BACK FOR SERVICE. I CHANGE GAS TO SHELL AS RECOMMENDED BY THE DEALER, AND THE PROBLEM PERSISTS. DEALER SAID THAT THIS IS COMON PROBLEM AND BLAMED IT ON THE GASOLINE BLEND. *TR

WHEN THE CAR DECELERATES (BRAKING OR DOWN-SHIFTING) THE HEADLIGHTS FLASH. WHEN I TAKE THE CAR BACK TO MAZDA SERVICE, THEY TELL ME THAT THIS IS A KNOWN ISSUE THAT IS EFFECTING MANY OF THE NEW SKYACTIV ENGINES. THEY SAY THAT THERE IS SOMETHING WRONG WITH THE ELECTRONIC CONTROL UNIT THAT IS MAKING THE LIGHTS FLASH. THEY STATE THAT MAZDA ENGINEERS HAVE NOT GIVEN THEM A FIX FOR IT YET, SO THEY CAN'T FIX IT. I BELIEVE THIS IS A REAL SAFTEY HAZARD. PEOPLE ON THE HIGHWAY THINK I AM FLASHING MY LIGHTS AT THEM. I BOUGHT A SECOND CAR (SAME MODEL AND YEAR) AT THE SAME TIME AND IT DOESN'T HAVE THIS PROBLEM. WHEN I TELL THIS TO MAZDA, THEY ACT SURPRISED AND STATE THAT I MUST HAVE GOT LUCKY BECAUSE MOST OF THE CARS HAVE THESE FLASHING LIGHTS. THEY SEEM TO JUST WANT ME TO LIVE WITH IT. YOU NEED TO INVESTIGATE THIS SINCE THEY ARE SAYING IT IS A COMMON ISSUE. I THINK THESE CARS NEED A RECALL. *TR
