2014 Mazda Mazda6 Powertrain (other) Problems

At 70000 miles the transmission just got stuck into a single gear in manual. I drove it home and the check engine light came on. Before this problem the car would not go into park. Every time I put it into park I was unable to turn off the car because it thought it was still in gear. I had to fiddle the gear stick. The car also made a high pitch click (metallic) when shifting into 1st or Reverse from park. I took it to Capitol Mazada San Jose and they charged me $7000 to fix some transmission problem. I took it home and the clicking noise did not go away. I took it back to the dealer and they redid some work.

EARLY 2014 MAZDA 6'S WERE EQUIPPED WITH DEFECTIVE TRANSMISSIONS. TO THE BEST OF MY UNDERSTAND A BEARNING OF THE WRONG DIAMETER WAS INSTALLED LEADING TO AN INITIAL SYMPTOM OF A HIGH PITCHED WHINE AT HIGHWAY SPEEDS. MAZDA'S SOLUTION IS TO REPLACE THE TRANSMISSION, BUT IF IT'S OUT OF WARRANTY THIS COMES AT THE CUSTOMER'S OWN COST (~$5,000). THERE HAS BEEN A TSB ABOUT THIS FOR YEARS NOW #05-005-15-3027A. THE ISSUES ARE THAT THERE IS NO TELLING WHEN THE SYMPTOMS WILL OCCUR AND WHEN I ASKED MAZDA WHAT WOULD HAPPEN TO THE TRANSMISSION IF I WASN'T REPLACED, THEY DECLINED TO GIVE ME AN ANSWER. IT IS OF CONCERN TO THE SAFETY OF DRIVERS THAT MAZDA DEAL WITH THIS PROBLEM.

ENGINE WON'T SHUT OFF SOMETIMES WHEN AUTOMATIC TRANSMISSION IS IN PARK. PUSH THE ENGINE OFF BUTTON THE ENGINE IS OFF ACCESSORIES AND INSTRUMENT PANEL LIGHTS ARE ON AS IF TRYING TO START THE ENGINE. PUSH THE ENGINE START BUTTON STARTS THE ENGINE. IT'LL KEEP CYCLING THESE TWO MODE AND CAN'T TURN OFF ENGINE COMPLETELY. DEALER KNOWS ABOUT THIS PROBLEM OCCURRING IN MAZDA6. $400 TO REPLACE SHIFTER ASSEMBLY. THEY SUGGEST I SHIFT THE TRANSMISSION INTO NEUTRAL W/ BRAKES ON TO TURN OFF ENGINE, THEN SHIFT TO PARK. CHANCE OF ACCIDENT INCREASE WITH THIS "SUGGESTION".

PROBLEM WITH SHIFT CONTROL/PARK SWITCH.. CAR WOULD BE IN A STATIONARY POSITION AND IGNITION WOULD BE SHUT DOWN. INTERIOR CONTROLLED ITEMS (I.E. RADIO, HEAT/AIR SYSTEM, LIGHTING, ETC. WOULD REMAIN ON AND WOULD NOT SHUT OFF. I WOULD ATTEMPT TO START/RESTART VEHICLE TO SEE IF THE CAR (AND ALL SYSTEMS) WOULD SHUT DOWN - THEY WOULD NOT. ONLY WAY I COULD COMPLETELY TURN OFF THE CAR AND ALL SYSTEMS WAS TO PLACE THE CAR IN REVERSE OR DRIVE MODE AND THEN PUT THE CAR BACK IN THE PARK POSITION. THIS OPTION WORKED FOR A SHORT WHILE AND THEN IT STOPPED WORKING. MY BATTERY WAS COMPLETELY DRAINED AND I ENDED UP REPLACING MY CAR BATTERY AND ULTIMATELY I HAD TO TAKE MY CAR INTO AN AUTHORIZED MAZDA DEALER TO HAVE THE GEAR PARK SWITCH BUTTON REPLACED. DEALER STATED THEY HAD NUMEROUS CUSTOMERS THAT EXPERIENCE SAME PROBLEM AND RESOLUTION. I CHECKED ONLINE AND SAW MANY CUSTOMERS ALSO EXPERIENCED SAME PROBLEM AND SAME NECESSARY REPAIR TO THE VEHICLE. BATTERY REPLACEMENT WAS APPROXIMATELY $130.00 AND THE GEAR/PARK SWITCH REPAIR WORK WAS $245.37. I HAVE A COPY OF THE INVOICE FOR THE REPLACEMENT AND REPAIR WORK, BUT AM UNABLE TO SCAN.

OFTEN WHEN SHUTTING OFF THE CAR, THE ENGINE SHUTS OFF BUT THE IGNITION AND AUXILIARY POWER REMAIN ON. THERE IS A MESSAGE ON THE DASH REQUESTING TO SHIFT LEVER TO P (PARK) BUT THE LEVER IS ALREADY POSITIONED IN P. IT WILL TAKE SEVERAL ATTEMPTS OF SHIFTING IN AND OUT OF P TO GET THE CAR TO COMPLETELY SHUT OFF ALL POWER.

IGNITION DOES NOT TURN OFF WHEN START/STOP BUTTON IS PRESSED--INTERMITTENT PROBLEM. THE VEHICLE MAY NOT START OR MAY NOT TURN OFF WHEN THE START/STOP BUTTON IS PRESSED. IT MAY NOT BE POSSIBLE TO SECURE THE VEHICLE IF THE IGNITION DOES NOT TURN OFF. THE PROBLEM BEGAN A FEW MONTHS AGO, HAS BECOME MORE AND MORE FREQUENT. WE ARE CONCERNED THE VEHICLE WILL FAIL IN SOME UNANTICIPATED WAY WHILE WE ARE DRIVING IT. MAZDA HAS IDENTIFIED THE PROBLEM AS RELATING TO THE TRANSMISSION SHIFT SWITCH. THE ORIGINAL PART MATERIAL HAS BEEN REPLACED BY MORE DURABLE MATERIAL, SO THE MANUFACTURER RECOGNIZES THE ORIGINAL PART WAS NOT DURABLE ENOUGH.FOR DETAILS, PLEASE GO TO HTTPS://MAZDA.OEMDTC.COM/665/IGNITION-DOES-NOT-TURN-OFF-WHEN-PRESSING-STARTSTOP-BUTTON-2013-2014-MAZDA#MORE-665

CAR DOES NOT TURN OFF AFTER PUSHING START/STOP BUTTON. ENGINES TURNS OFF BUT BATTERY, RADIO ETC STAYS ON. GEAR IS ON PARK AND E BRAKE IS UP. READ OTHER FORUMS WHERE MANY OTHER PEOPLE ARE HAVING THE SAME ISSUE. AN IMMEDIATE FIX IS TO JIGGLE THE GEAR AND THEN PUSH THE BUTTON AGAIN. THE GEAR SEEMS TO BE LOOSE OR THE IGNITION SWITCH UNIT IS FAULTY ACCORDING TO RESEARCH ONLINE. CAR IS PARKED AND SEEMS TO BE HAPPENING MORE OFTEN. STARTED HAPPENING ABOUT 3 YEARS AFTER PURCHASED BRAND NEW.

TL* THE CONTACT OWNS A 2014 MAZDA 6. WHILE PULLING INTO THE PARKING SPOT AND DEPRESSING THE BRAKE PEDAL TO STOP THE VEHICLE, IT SUDDENLY ACCELERATED. THE VEHICLE CRASHED INTO A TREE AND THE ENGINE CONTINUED TO REV AS IF ATTEMPTING TO CONTINUE ACCELERATING. THE AIR BAGS DID NOT DEPLOY. THE CONTACT SUSTAINED BRUISES TO THE UPPER BODY, WHICH DID NOT REQUIRE MEDICAL ATTENTION. A POLICE REPORT WAS NOT FILED. THE VEHICLE WAS TOWED TO A COLLISION CENTER FOR DIAGNOSTIC TESTING. THE MECHANIC WAS ABLE TO FEEL THE VEHICLE ATTEMPTING TO ACCELERATE ON ITS OWN. THE VEHICLE WAS TAKEN TO THE SEA COAST MAZDA DEALER, BUT THE CAUSE OF THE FAILURE WAS UNDETERMINED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 14,000. UPDATED 09/07/17*LJ

MY AUTOMATIC 2014 MAZDA 6 TOURING DOWN-SHIFTS THE TRANSMISSION WHEN THE "HANGUP" OR "ANSWER" BUTTON ON THE STEERING WHEEL IS PRESSED WHILE THE CAR IS IN MOTION. THIS ISSUE WAS RECOGNIZED BY ME ON SATURDAY MAY 20, 2017. I WAS CONNECTED TO BLUETOOTH SPEAKING WITH MY WIFE WHILE DRIVING HOME FROM WORK TRAVELING APPROXIMATELY 65MPH ON THE FREEWAY. WHEN I ATTEMPTED TO PRESS THE "HANGUP" BUTTON ON MY STEERING WHEEL, MY VEHICLE DOWNSHIFTED GEARS CAUSING MY CAR TO REV UP TO 5,000-6,000 RPM. WITHOUT FIRST REALIZING THE CAUSE AND IN AN ABSOLUTE PANIC, I ATTEMPTED TO PUT MY CAR INTO NEUTRAL AND THEN BACK INTO DRIVE IN ORDER FOR THE TRANSMISSION TO CATCH THE CORRECT GEAR; ALL WHILE DRIVING 65MPH ON THE FREEWAY. THIS MANEUVER ALLOWED THE VEHICLE TO CORRECT ITSELF TO THE APPROPRIATE RPM. I LATER LEARNED THAT MULTIPLE PRESSES OF EITHER THE "HANGUP" OR "ANSWER" BUTTON WILL DOWNSHIFT THE VEHICLE FURTHER REGARDLESS OF THE SPEED THE VEHICLE IS TRAVELING, THEREFORE INCREASING THE RISK OF SURPASSING SAFE RPMS WHILE DRIVING. I WAS ABLE TO REPRODUCE THIS EFFECT EVERY TIME THEREAFTER. I BROUGHT MY CAR TO THE DEALERSHIP ON TUESDAY MAY 23, 2017 AND THEY CLAIMED TO "NEVER HEARD OF THAT BEFORE". THE DEALER CLAIMS TO HAVE IDENTIFIED THE ISSUE AND SUGGESTS "REPLACING THE SPIRAL CABLE BEHIND THE STEERING WHEEL." FOR REFERENCE, MY VEHICLE DOES NOT HAVE PADDLE SHIFTERS. I AM VERY VERY CONCERNED ABOUT PUSHING OTHER BUTTONS IN MY VEHICLE IN FEAR THAT SOMETHING ELSE MAY CAUSE ME TO LOSE CONTROL AND CRASH MY VEHICLE - INJURING MYSELF OR OTHERS.

I WAS AT A STOPLIGHT WITH MY FOOT ON THE BRAKE WHEN THE ENGINE STARTED TO REV UP, THEN I HEARD A THUD AND THE CAR LURCHED FORWARD AND IT FELT LIKE I WAS HIT FROM BEHIND. I PULLED OVER TO CHECK FOR DAMAGE BUT NOTHING. THIS IS A SAFETY ISSUE AND THERE SHOULD BE A RECALL AS I SEE ON THE WEB OTHERS ARE HAVING THE SAME EXPERIENCE. THE CAR IS GOING TO THE MAZDA DEALER ASAP TO SEE IF THEY CAN CORRECT THE PROBLEM.

UPON TURNING ON MY CAR (FLAT SURFACE, MIDDLE OF THE DAY, ALREADY DRIVEN THAT MORNING), I RECEIVED AN AT FAILURE NOTICE, MASTER WARNING LIGHT, SCBS FAILURE NOTICE, AND A CHECK ENGINE LIGHT. THE CAR HAD BEEN SEEN 5 DAYS PRIOR FOR A ROUTINE OIL CHANGE AND INSPECTION. ALL MARKS WERE NOTED AS "GREEN." THE ENGINE SOUNDED FINE, THE SHIFTING OF THE TRANSMISSION SMOOTH, AND NO ISSUES WERE SEEN/FELT/HEARD/NOTICED AS OF YET. THE DEALER REFUSED TO RUN A DIAGNOSTICS TEST AS IT IS A SATURDAY.

AFTER DRIVING MY LINCOLN MKZ, WHERE PRESSING THE IGNITION STOP BUTTON AUTOMATICALLY PUTS THE CAR IN PARK, I DROVE MY FRIEND'S 2014 MAZDA6. I PRESSED THE IGNITION STOP BUTTON BUT EXITED THE VEHICLE WITHOUT PUTTING IT IN PARK. I DID NOT NOTICE ANY WARNING THAT THE CAR HAD BEEN TURNED OFF AND EXITED WITHOUT BEING IN PARK. THE CAR, ALTHOUGH STATIONARY WHEN WE LEFT IT, ENDED UP ROLLING INTO ANOTHER CAR IN THE PARKING LOT. MY INITIAL ESTIMATE IS THAT THE TOTAL DAMAGE WILL EXCEED $5,000 TO BOTH CARS. IF THIS CAR HAD HAD AN IGNITION KEY, I WOULD HAVE BEEN FORCED TO PUT IT IN PARK AS I REMOVED THE KEY. PLEASE CONSIDER REQUIRING A VOICE WARNING THAT CAR HAS BEEN TURNED OFF AND/OR EXITED WITHOUT BEING IN PARK. I THINK OUR 2014 LINCOLN MKZ PUTS ITSELF IN PARK IF YOU EXIT THE VEHICLE. *JS

THIS INCIDENT HAS HAPPENED ABOUT 10 - 15 TIMES IN THE 6 MONTHS I HAVE HAD THIS CAR. IT OCCURS WHEN THE VEHICLE IS STOPPED AT A TRAFFIC SIGNAL, STUCK IN TRAFFIC, OR ANY OTHER TIME WHEN THE TRANSMISSION IS IN DRIVE AND THE BRAKE IS USED TO KEEP THE VEHICLE STATIONARY. THE ENGINE WILL BE TURNING AT IDLE SPEED WHEN SUDDENLY IT REVS TO 4-5K RPM CAUSING THE CAR TO LEAP FORWARD, OVERPOWERING THE BRAKE. THIS HAS ALMOST RESULTED IN A CRASH SEVERAL TIMES AS SUDDENLY THE CAR MOVES FORWARD RAPIDLY. I HAVE NOTICED A SMALL TENDENCY FOR THIS TO OCCUR IN THE FIRST FEW MINUTES OF DRIVING BUT IT HAS HAPPENED ANYTIME. I HAVE SEEN NO CORRELATION TO OUTSIDE TEMPERATURE. I HAVE NOTICED PERHAPS A SMALL INCREASE IN FREQUENCY WHEN THE CAR IS STOPPED AFTER HIGH SPEED DRIVING SUCH AS HIGHWAY DRIVING. *TR

THE VEHICLE STARTED TO DECELERATE WHILE DRIVING WITHOUT ANY TYPE OF NOTICE. THE DEALERSHIP FOUND OUT THE VALVE BOARD IN THE TRANSMISSION NEEDED TO BE REPLACED. THE PROCESS TOOK 3 WEEKS TO REPAIR SINCE THE VALVE BOARD WAS ON BACK ORDER DUE TO HIGH DEMAND. THE VEHICLE WAS REPAIRED BUT THERE IS STILL A DELAY WHEN ACCELERATING AT CERTAIN SPEEDS. THE DEALERSHIP HAS YET TO FIND OUT WHAT IS CAUSING THE CURRENT ISSUE THAT MY VEHICLE IS HAVING. *TR
