2006 MAZDA MAZDA3 Engine Problems

MY ENGINE HAS A SUDDEN BURST OF ACCELERATION. I HAVE TO ALWAYS BE READY TO DROP IT INTO NEUTRAL IT HAPPENS UPON THE CAR STARTING TO MOVE

CAR CONTINUINGLY SHOWS EVAP DTCS INCLUDING P0443 AND P0446 AS WELL AS EITHER TOO RICH OR TOO LEAN FUEL MIXTURE AND AND O2 SENSOR ISSUE CODE. BOTH O2 SENSORS WERE REPLACE PREVIOUSLY. THE MAIN CONCERN IS DANGEROUS AND HAS ALREADY ALMOST CAUSED SEVERAL ACCIDENTS WHILE THE ISSUE HAS OCCURRED AFTER DRIVING FROM A STOPPED POSITION. THE ISSUE IS, WHEN THE VEHICLE STOPS AT 0 MPH, THE NORMAL IDLING RPM SPEED IS AROUND 750RPM. DURING STOPS LONGER THAN A SECOND, THE CAR WILL LOWER THE IDLE RPMS TO ABOUT 500RPM AND STAY UNTIL THE THROTTLE IS ENGAGED. WHEN THE THROTTLE IS ENGAGED THE VEHICLE HESITATES AND COMES CLOSE TO STALLING. THE VEHICLE WILL NOT POWER THE WHEELS ABOVE ABOUT 1000RPMS WHEN THE THROTTLE IS FULLY DEPRESSED AND THE CAR WILL HESITATE UNTIL THE CAR STARTS TO GRADUALLY MOVE FORWARD. THIS ALL IS HAPPENING IN THE INTERSECTION. AS THE CAR GETS TO...

MAZDA3 ABRUPTLY AND UNEXPECTEDLY SHIFTED FROM 5TH GEAR DOWN TO 3RD GEAR ON ITS OWN WHILE TRAVELING AT HIGHWAY SPEEDS. THE CAR JERKED VIOLENTLY AND THE TRANSMISSION LIGHTS CAME ON. SEEMED LIKE THE STEERING/TRACTION WAS IMPAIRED. CAUSED THE MOTOR TO WRACK AND BLOW RENDERING THE CAR INOPERABLE. TOWED IT TO A REPAIR SHOP WHERE THEY DETERMINED THAT SHIFTING THAT SUDDENLY CAUSE THE MOTOR TO BLOW. HAD ISSUES IN THE PAST WITH THE SAME TRANSMISSION PROBLEM AND HAD IT REPAIRED, TURBINE SPEED SENSOR. THIS LAST OCCURRENCE AFFECTED NOT ONLY THE TRANSMISSION BUT THE ENGINE AS WELL. HAS CONSTANTLY HAD MOTOR MOUNT ISSUES, AS WELL, WHICH REQUIRED REPAIRS. THIS IS VERY UNSAFE BEHAVIOR AND IS UNACCEPTABLE. WHY HAS THIS NOT BEEN RECALLED?

MY CAR IDLES REALLY ROUGH. ONCE I GET CLOSE TO FREEWAY SPEED MY CAR CONSTANTLY SHIFTS GEARS FROM 3 TO 4 TO 3, SO ON. THIS CAUSES MY CAR TO JERK, IT REVS FROM 3,000 TO 1,000 AND EVEYTHING IN BETWEEN. DURING THIS MY BRAKES BECOME PRACTICALLY USELESS, I HAVE TO COMPLETELY PRESS THE BRAKE PEDAL TO MAKE IT DECELERATE. AND BRAKING DISTANCES ARE DRASTICALLY INCREASED. IT FURTHER WORRIES ME THAT I DONT HAVE ANY DASH LIGHTS ON SUCH AS CHECK ENGINE, TRANSMISSION, ABS, ETC.

I WAS DRIVING ON THE INTERSTATE WHEN ALL OF THE SUDDEN MY CAR WENT FROM 5TH GEAR TO NEUTRAL...THE CAR JERKED/BUCKED AND I WAS THROWN INTO THE LANE NEXT TO ME. THANK GOODNESS I DID NOT HIT ANYONE ELSE OR CAUSE AN ACCIDENT. EVEN DRIVING IN TOWN THE CAR DOES NOT GET INTO GEAR LIKE IT SHOULD AND STALLS OUT THEN BUCKS ABRUPTLY. THE AT LIGHT FLASHES AND ENGINE LIGHT CAME ON. HAD THE CAR DIAGNOSED BY 3 DIFFERENT SHOPS AND THE DEALER AND WAS TOLD IT WAS THE TCM (TRANSMISSION CONTROL MODULE). MY 2006 MAZDA3 HAS BEEN MAINTAINED EXTREMELY WELL AND ALWAYS SERVICED WHEN SUGGESTED. I JUST HIT 95K MILES. I HAVE NOT HAD ANY OTHER PROBLEMS BESIDES THIS ONE. I'M EXTREMELY CONCERNED FOR MY SAFETY WHEN THIS PROBLEM HAPPENS WITH THE TRANSMISSION SO I HAVE TRIED TO GET IT FIXED PROMPTLY BUT NONE OF THE AUTO SHOPS CAN...

I WAS ON A FREEWAY OFF-RAMP AT APPROXIMATELY 50 MPH, WHEN LOUD GRINDING AND CRASHING NOISES CAME FROM UNDER THE HOOD. THE CAR THEN BECAME DIFFICULT TO STEER, AND WOULD NO LONGER PROPEL ITSELF. I COASTED INTO A DRIVEWAY NEAR THE BOTTOM OF THE OFF-RAMP. UPON INSPECTION, I DISCOVERED THAT THE TRANSMISSION "MOTOR MOUNT" HAD BROKEN. THE ENGINE APPARENTLY LUNGED FORWARD, SHEERING OFF BOLTS TO THE OTHER MOTOR MOUNTS, AND LANDED ON THE SUSPENSION, SEVERELY DAMAGING MANY FRONT-END PARTS. THE CAR WAS TOWED TO THE NEAREST MAZDA DEALERSHIP, WHOSE SERVICE DEPARTMENT CONFIRMED MY ASSESSMENT OF WHAT HAD OCCURRED. THE REPAIR ESTIMATE IS APPROXIMATELY $3,000. BEFORE THE INCIDENT, THE CAR WAS IN EXCELLENT CONDITION, HAVING BEEN WELL-MAINTAINED. (I HAVE SERVICE RECORDS.) I DISCOVERED THAT MAZDA HAD RECALLED A NUMBER OF MAZDA 3'S FOR MOTOR MOUNT PROBLEMS, BUT MY CAR WAS NOT AMONG THOSE RECALLED. WHILE THE CAR IS NO LONGER UNDER...

VEHICLE HAS HAD, ON SEVERAL DIFFERENT OCCASIONS, BEEN DRIVEN, NOT AT ANY PARTICULAR SPEED AND LOST 4TH GEAR, THE ENGINE LIGHT APPEARS, AN AT LIGHT APPEARS, AND THE BRAKES ARE APPLIED TO DOWNSHIFT THE CAR DOWN TO 3RD GEAR. UPON ME NOTICING THIS. I WAIT UNTIL IT IS SAFE TO STOP AT A RED LIGHT OR STOP SIGN AND MAKE A COMPLETE STOP SHIFT THE CAR INTO PARK AND BACK INTO DRIVE. THIS SEEMS TO FIX THE DISAPPEARANCE AND REMOVAL OF THE 4TH GEAR AS WELL AS THE AT LIGHT, BUT ONLY OCCASIONALLY. IT DOES NOT HOWEVER REMOVE THE ENGINE LIGHT. THOUGH AFTER A FEW DIFFERENT TRIPS ON DIFFERENT DAYS THE LIGHT WILL NOT APPEAR ON START UP AND DOES NOT SHOW UP UNTIL THIS ISSUE HAPPENS AGAIN. THE CAR SHOWS ERROR CODE P0715 AND IS POSSIBLY NEEDING A NEW TRANSMISSION SPEED SENSOR. THIS ISSUE HAS NOT BEEN FIXED.

THE ENGINE WAS COLD. I ENTERED THE CAR, STARTED THE ENGINE, SHIFTED INTO REVERSE AND THE ENGINE ACCELERATED UNCONTROLLABLY, SCREAMING. I COULD NOT STOP THE CAR WITH FULL BRAKING AND SHUT OFF ENGINE. I RESTARTED AND IT WORKED NORMALLY. THIS ALSO HAPPEN ABOUT A YEAR AGO AND THE DEALER COULD FIND NOTHING WRONG. HELP!!!! *TR

TL* THE CONTACT OWNS A 2006 MAZDA 3. WHILE AT A STOP LIGHT, THE OIL PRESSURE WARNING LIGHT ILLUMINATED AND THE VEHICLE STALLED. THE CONTACT WAS UNABLE TO RESTART THE VEHICLE. UPON FURTHER INSPECTION, THE CONTACT NOTICED THAT THE OIL HOUSING FILTER FRACTURED. THE CONTACT DIAGNOSED THAT THE MOTOR NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 150,000.

THE TOP ENGINE MOUNT IS POORLY BUILT! THE RUBBER INSERT DOESN'T LAST LONG ENOUGH. METAL PART IS NOT VERY STURDY! *TR

I WAS DRIVING ALONG AND SUDDENLY A LOUD NOISE, THE CHECK ENGINE LIGHT CAME ON AND THE CAR SHIFTED FROM 4TH TO 3RD WITHOUT LOSING SPEED (EXCEPT FROM ME TAKING MY FOOT OFF OF THE GAS WHEN HEARING THE NOISE) ALL AT THE SAME TIME. MY MECHANIC SAID THE DIAGNOSTIC MACHINE POINTED TO THE "TURBINE SPEED SENSOR", SO THIS WAS REPLACED WITHIN 2 DAYS. THE SAME DAY I GOT THE CAR BACK, I DROVE IT ABOUT 30 MILES AND IT DID THE SAME THING AGAIN. NOW MY MECHANIC IS CHECKING INTO THE TRANSMISSION, POSSIBLY CAUSING THE PROBLEM. *TR

MOTOR MOUNTS FAIL. THERE IS ALREADY AN EXISTING COMPLAINT. WE HAVE HAD TO REPLACE THREE OF THE FOUR MOTOR MOUNTS AT VARIOUS TIMES STARTING FROM 1,000 MILES TO 76,000 MILES. *TR

TL* THE CONTACT OWNS A 2006 MAZDA MAZDA3. THE CONTACT STATED THAT WHILE TRAVELING APPROXIMATELY 65 MPH, HE HEARD A LOUD KNOCKING NOISE AS THE VEHICLE SPONTANEOUSLY COMBUSTED. THE CONTACT MENTIONED THAT THE FLAMES ORIGINATED FROM UNDER THE HOOD AREA. THE POLICE AND FIRE DEPARTMENT WERE SUMMONED TO THE SCENE. THERE WERE NO INJURIES AND A POLICE REPORT WAS NOT FILED. THE VEHICLE WAS DESTROYED AND WAS NOT DIAGNOSED TO DETERMINE THE CAUSE OF THE FAILURE. THE MANUFACTURER WAS NOT CONTACTED ABOUT THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 134,000.

ENGINE MOUNT NO 3 (LOCATED ON FRONT LEFT SIDE OF THE ENGINE, UNDER THE WASHER FLUID RESERVOIR) FAILED. THIS TYPE OF FAILURE IS VERY FREQUENT WITH THIS MODEL. THE FAILURE JEOPARDIZES THE STRUCTURAL STABILITY OF THE ENGINE. THIS SHOULD BE A RECALL. *TR

TL* THE CONTACT OWNS A 2006 MAZDA MAZDA3. WHILE DRIVING APPROXIMATELY 30 MPH, THE POWER STEERING WARNING LIGHT ILLUMINATED ON THE INSTRUMENT PANEL. THE STEERING WHEEL BECAME DIFFICULT TO MANEUVER. THE CONTACT DEPRESSED THE BRAKE PEDAL BUT THE BRAKES WOULD NOT RESPOND. THE VEHICLE SUDDENLY STALLED WHILE MAKING A LEFT TURN. THE FAILURE RECURRED INTERMITTENTLY. THE CONTACT STOPPED THE VEHICLE IN A PARKING AREA AND AFTER RESTARTING THE VEHICLE, THE STEERING AND BRAKES RESPONDED. THE VEHICLE WAS NOT TAKEN TO THE DEALER FOR DIAGNOSTIC TESTING. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 80,000.

RUBBING SOUND COMING FROM FRONT PASSENGER WHEEL WHEN TURNING HARD RIGHT, AS WELL AS WHEEL HOP. DIAGNOSED AS A BROKEN ENGINE MOUNT WHICH LED TO A BROKEN STRUT. BOTH HAD TO BE REPLACED. MAZDA REFUSES TO FIX, DESPITE NUMEROUS REPORTS OF BAD ENGINE MOUNTS. *TR

FIVE TIMES IN THE LAST MONTH I HAVE EXPERIENCED PROBLEMS WHEN MAKING LEFT TURNS. THE POWER STEERING MOMENTARILY SHUTS OFF, AND THE RADIO/ELECTRICAL SYSTEM SHUTS OFF MOMENTARILY AS WELL. ON ONE OCCASION THE ENGINE ALSO SHUT OFF MOMENTARILY (FOR ABOUT ONE FULL SECOND). WHEN THIS HAPPENS, I FEEL A COMPLETE LOSS OF CONTROL OVER THE VEHICLE. TWO DIFFERENT INDEPENDENT MECHANICS TOLD ME THAT THEY COULD NOT FIX THE PROBLEM AND THE MAZDA DEALERSHIP REFUSES TO DIAGNOSE THE PROBLEM WITHOUT CHARGING ME BECAUSE THE PROBLEM IS NOT A RECALL, AND THE CAR IS NOT UNDER WARRANTY. THERE IS A RECALL FOR A VERY SIMILAR ISSUE WITH THE 2007 MODEL OF MAZDA 3S, BUT THE 2006 MODELS ARE NOT INCLUDED IN THAT RECALL. *TR
