2009 Mazda Mazda6 Electrical System Problems

The sensors on my alarm system will randomly activate, with alarm going off at 30 second intervals. The problem began approximately 6 months ago. I took the initiative to replace my cars battery, along with the battery in my fab. I really thought that solved my problem, as a first step fix. I began once again to identify the sound of my car alarm in multiple parking lots throughout time. I have been investigating this problem, and have read that this alarm problem has been sited by many Mazda 6 owners. I am the original owner of the 2009 Mazda 6 Grand Touring, and have 67,000 miles driven. I called the Repair Department at my dealership, and was told that it cost $185.00 for just the diagnosis. My auto insurance company policy price is based on using a secured vehicle. Right now I only can leave it unlocked in my garage, otherwise, my vehicle is at risk of being stolen.

The driver's side low beam headlight wiring harness melts and seems to be continuing problem. Even after replacing stock, (which melted,) with a better wiring harness it still began to melt and loose circuit, but like I said it was doing this before ever being replaced. Happens every couple months are so depending on amount of night driving. I have read several complaints about this happening to several owners of the same vehicle on the same drivers side with the same original harness and replacements doing this same melting and frequent on/off short circuit malfunctioning. Possibly causing a fire or fried wiring or loss of headlight causing unsafe conditions

THE OTHER DAY WENT TO DRIVE THE CAR WOULD NOT START. NO ACC ON REMOTE START BUTTON, KEY IN IGNITION, STILL WOULD NOT START. CHECKED ALL FUSES, THE BATTERY. TOOK DASH APART, REMOVED STEREO, CHECKED ALL WIRING HARNESSES ALL TESTED GOOD. HAD IT TOWED UP TO OLYMPIA MAZDA. THEY ARE CURRENTLY TROUBLESHOOTING. RECALLED AIRBAG WAS SWITCHED OUT A FEW YEARS AGO AND THE WARNING LIGHT CAME BACK ON ABOUT A YEAR LATER. POSSIBLY THE CAR THINKS THERE HAS BEEN AN COLLISON AND THE CAR IS IN LOCKDOWN MODE. TECHNICIAN WAS COMPLETELY BAFFLED. WILL CALL THEM TOMORROW AND ASK THEM TO CHECK THE ECM, BCM OR WHAT NOT. OTHER THAN THIS. HAVE NEVER HAD AN MECHANICAL ISSUE WITH THIS CAR. WOULD PURCHASE AGAIN.

I BOUGHT A USED CAR FROM A SMALL DEALERSHIP, THEY SOLD ME THE CAR WITHOUT A DASH HARNESS, ALL THE WIRING THAT IS SUPPOSED TO BE CONNECTED TO THE COMPUTER IN MY CAR IS NOT THERE, SO I CAN'T DO SMOG CHECK. THE MECHANIC COULD NOT CHECK WHY THE CHECK ENGINE LIGHT WAS ON BECAUSE THE COMPUTER IN MY CAR WAS NOT COMMUNICATING WITH THE TOOL. SOLD ME THE CAR WITH AIRBAGS NOT WORKING. LIED ABOUT HAVING IT ALL CHECKED OUT. AND I STILL HAVEN'T RECEIVED MY TITLE, REGISTRATION, AND PLATES TO MY CAR.

FOR THE LAST YEAR, THE CAR ALARM IN MY 2009 MAZDA 6 HAS BEEN GOING OFF SPORADICALLY BY ITSELF AT ALL HOURS OF THE DAY WHILE PARKED IN MY APARTMENT BUILDING PARKING LOT. THE DEALER DIAGNOSED THAT MY PASSENGER SIDE DOOR ACTUATOR NEEDED TO BE REPLACED. IT WAS, AND A FEW WEEKS LATER THE ALARM WENT OFF AGAIN AT 3:30 AM, WAKING UP ALL OF MY NEIGHBORS IN THE PROCESS. BROUGHT IT BACK TO THE DEALER AND NOW THEY SAY IT'S THE DRIVER SIDE DOOR ACTUATOR. THERE ARE SO MANY REPORTS ON THE INTERNET OF OTHER MAZDA OWNERS HAVING THIS SAME ISSUE AND THERE IS A BULLETIN OUT THERE FOR IT. WHY HAS BEEN THIS NOT BECOME A RECALL YET?

ON JANUARY 25, 2014, I HAD MY CAR SERVICE AT A S. FLORIDA MAZDA DEALERSHIP FOR A 2013 RECALL ON THE DOOR LATCH MOUNTING SCREWS. THE RECALL STATED THAT THE SCREWS MAY BECOME LOOSE. IF ALL THREE DOOR LATCH MOUNTING SCREWS BECOME LOOSE AND FALL OUT, THE DOOR LATCH MECHANISM WILL NOT ENGAGE WHEN THE DOOR IS CLOSED, AND THE DOOR AJAR WARNING LIGHT WILL ILLUMINATE. CURRENTLY, I AM EXPERIENCING THE SAME ISSUE WITH MY DOORS AND THE DOOR AJAR LIGHT ILLUMINATING. IN ADDITION, DUE TO THIS ISSUE, MY BATTERY THAT I HAD REPLACED IN MAY 2020 DOES NOT WORK. MY CAR DID NOT START. I HAD TO HAVE MY CAR TOWED TO THE NEAREST MAZDA DEALERSHIP. THE DEALERSHIP REPLACED THE BATTERY BUT TOLD ME THAT MY DOOR LATCH ON 2 DOORS HAD TO BE REPLACED BECAUSE MY CAR THINKS THE DOOR IS AJAR AND THIS CAUSES THE BATTERY TO DRAIN EVEN WITH THE CAR TURNED OFF. IT SOUNDS LIKE THESE ISSUES COULD BE ATTRIBUTED TO THE 2013 RECALL. FURTHERMORE, THE TECHNICIAN INFORMED ME THAT MY CAR ALARM GOES OFF WITHOUT WARNING AND THE TECHNICIAN ATTRIBUTED THIS TO THE DOOR LATCH ISSUE. SO ALL OF THE ABOVE ISSUES CAN BE TRACED BACK TO THE 2013 RECALL ON DOOR LATCHES. IT APPEARS THAT THERE IS A MANUFACTURER DEFECT ON THE DOOR LATCHES. THEREFORE, THE DEALERSHIP SHOULD MAKE THE NECESSARY REPAIRS WITHOUT CHARGE TO ME. RIGHT NOW, MY CAR HAS BEEN AT THE DEALERSHIP FOR 1 WEEK AND 2 DAYS.

THE DOOR LOCK ACTUATORS GO BAD ON THIS CAR WHICH CAUSES THE CAR TO BELIEVE ONE OF THE DOORS IS OPEN WHEN IT IS NOT. THE DOME LIGHTS ARE DRIVEN BY THE DOOR ACTUATORS SENSING THAT A DOOR IS OPEN, SO WHEN YOU ARE DRIVING, THE INTERIOR LIGHTS WILL FLASH ON AND OFF. VERY DISTRACTING, ESPECIALLY AT NIGHT. THE LIGHTS TURNING ON AND OFF ONLY HAPPENS WHEN THE CAR IS BEING DRIVEN, I HAVE NOT NOTICED IT WHEN STATIONARY. USUALLY IT OCCURS DURING TURNS AND THE LIGHTS STAY ON FOR A FEW SECONDS. THE DOOR ACTUATORS ARE A COMMON PROBLEM ON THIS CAR AND HAS MANY COMPLAINTS ABOUT THIS ISSUE ONLINE. THIS HAS BEEN GOING ON FOR SEVERAL MONTHS NOW. THE DOOR ACTUATOR BEING FAULTY ALSO CAUSES THE SECURITY ALARM TO GO OFF AND START SOUNDING THE CAR'S HORN SPORADICALLY. THE CAR WILL BE PARKED IN A DRIVEWAY WITH NOBODY AROUND THROUGH ALL HOURS OF THE DAY AND IT WILL GO OFF. ALTHOUGH NOT A SAFETY CONCERN LIKE THE PROBLEM WITH THE LIGHTS, IT IS STILL SYMPTOMATIC OF THE MALFUNCTIONING DOOR ACTUATORS.

HEADLIGHT HARNESS COMES LOOSE FREQUENTLY, RESULTING IN LOSS OF HEADLIGHT. MUST EITHER HIT THE HEADLIGHT FORCEFULLY OR MANUALLY SECURE HEADLIGHT BY REMOVING WHEEL WELL. HUNDREDS OF PEOPLE ON YOUTUBE HAVE REPORTEDLY EXPERIENCED THE SAME DEFECT. UNCERTAIN WHETHER THIS OCCURS WHILE STATIONARY OR MOVING, BUT IMAGINE VIBRATION FROM MOTION WILL KNOCK IT LOOSE AGAIN. THIS PHOTO WAS TAKEN AFTER MANUALLY ADJUSTING THE RIGHT HEADLIGHT VIA THE HARNESS IN ORDER TO TURN IT BACK ON. THE RIGHT LIGHT IS DIMMER THAN THE LEFT, SUGGESTING A GROUND ISSUE.

TAKATA RECALL - ASSURED BY DEALER PARTS FOR RECALL IN STOCK. DEALER KEPT ME THERE, WITHOUT HAVING THE PARTS, FOR HOURS WHILE SEARCHING FOR BILLABLE WORK. SUGGESTED $759 - $1059 UNRELATED SERVICE. CAREFUL POST-VISIT ANALYSIS INDICATED NO SUCK SERVICE NEEDED. NOW I'M WARY OF RETURNING FOR RECALL OR ANY OTHER REASON. HERITAGE MAZDA CATONSVILLE MD 21228 INVOICE #5MCS115194.

HORN HAS ACTIVATED RANDOMLY FOR YEARS NOW, THE FIRST INSTANCE OCCURRING ON OR ABOUT JULY, 2013. I HAVE BROUGHT THE CAR INTO THE DEALERSHIP MANY TIMES FOR THIS. EACH TIME THEY SAID THE DOOR LATCH WAS FAULTY AND SETTING IT OFF. I HAVE HAD 3 DOOR LATCHES REPLACED WITH THE MOST RECENT BEING DONE ON 5/2015. IN AUGUST 2016, THE HORN STARTED ACTIVATING RANDOMLY AGAIN. THE DEALERSHIP SAID THAT THEY FOUND "CODES" ON THE 3 DOOR LATCHES THAT WERE ALREADY REPLACED! CLEARLY THERE IS A DEFECT SOMEWHERE WITH THE DOOR LOCKS OR ITS ELECTRICAL COMPONENTS. THIS POSES A SEVERE SAFETY HAZARD AS A CHILD CAN OPEN THE DOOR LOCK AND FALL OUT WHEN THE VEHICLE IS MOVING IF THE LOCK IS NOT WORKING.

TL* THE CONTACT OWNS A 2009 MAZDA 6. THE CONTACT SMELLED A STRONG BURNING ODOR INSIDE AND OUTSIDE THE VEHICLE. AFTER ENTERING THE VEHICLE, THERE WAS EVIDENCE OF AN ELECTRICAL FIRE. THE FIRE DEPARTMENT RESPONDED; HOWEVER, THERE WERE NO VISIBLE FLAMES. THE ENTIRE INTERIOR OF THE VEHICLE WAS COVERED WITH SOOT AND SMOKE. THE VEHICLE WAS TOWED TO THE DEALER WHERE IT WAS DECTECTED THAT THE HARNESS CONNECTOR WIRES UNDERNEATH THE DRIVER'S SEAT WERE BURNT AND THE FUSE BOX OVERHEATED. THE VEHICLE WAS REPAIRED. NEITHER A FIRE NOR A POLICE REPORT WERE FILED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 110,000.

I BOUGHT A USED CAR WITH 2 DASHBOARD LIGHT TMPS & ENGINE THE DEALER GIVE ME EXTRA WARRANTY BUT NEVER BEEN REPAIR FURTHERMORE I FIND OUT BY MYSELF A RECALL FOR THE OUTER DOOR HANDLES AFTER THE DOOR OPEN WHILE I DRIVING IN THE EXPRESS WAY THIS HAPPENED TO MY YOUNGEST DAUGHTER; AND IN OTHER 2 INCIDENTS THE CAR DO NOT RESPOND WITH THE APPROPRIATE SPEED CAUSING ME A BIG CHANCE OF ACCIDENT AFTERWARDS IT IS HAPPENED AGAIN SO DUE TO OTHER SEVERAL MECHANIC PROBLEMS AND FOR SECURITY I HAVE TO DECIDED TO RETURN THE CAR NOW I HAVE NO MONEY NO CAR AND A BIG PROBLEM I AM HAVING HARDLY TIME TRIED TO SUMMIT MY CONCERNS BECAUSE I THINK THE DEALERS ARE RESPONSIBLE FOR SALE SECURITY CARS BEFORE THE SALE BUT APPARENTLY THE LAWS ARE IN THE DEALERS SIDE AS A CONSUMER I HOPE MAYBE SOME ONE CAN SEE HOW THIS IRRESPONSIBLE DEALERS PLAY WITH THE CONSUMERS SAFETY. I PAY OVER $3,000 IN REPAIRS BY MY SELF AND I HAVE BEEN AROUND 90 DAYS WITH OUT CAR AND ALL THIS PROBLEMS IN A PERIOD OF TIME OF 26 MONTHS PLUS MY PAYMENTS TO THE DEALER THAT WAS $460,00 A MONTH THIS ISSUE START ON 12-6-13 TO 02-26-16 AFTER THE CAR NEED A NEW REPAIR AT COST OF $3,000 SO IN THE REALITY THIS COMPANY WAS NEGLIGENT WHEN THEY FAIL TO PROPERLY REPAIR THE CAR SINCE THE BEGINNING THEY JUST PRETEND TO FIXED BUT WASN'T . I WANT TO THANK YOU FOR YOUR TIME. *TR

TL* THE CONTACT OWNS A 2009 MAZDA 6. DURING HIGHER HUMIDITY TEMPERATURES, THE VEHICLE'S ALARM RANDOMLY ACTIVATED. THE CONTACT WAS UNABLE TO DETERMINE IF THIS ISSUE WOULD AFFECT THE AIR BAGS. THE DEALER WAS NOTIFIED OF THE FAILURE SEVERAL TIMES AND WAS UNABLE TO PROVIDE A SPECIFIC DIAGNOSIS TO PROVIDE A PERMANENT REMEDY. THE DEALER INDICATED THAT THE VEHICLE RECEIVED A MANUFACTURER'S REPAIR FOR AN UNRELATED FAILURE. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 30,000.

THE PANIC ALARM HAS BEEN GOING OFF EVERY WEEK AT LEAST ONCE OR TWICE. THIS HAPPENS A LOT IN THE EVENINGS BETWEEN 8PM AND 11PM. IT'LL GO OFF BY ITSELF FOR NO REASON AT ALL. THIS HAPPENED ANOTHER TIME LAST YEAR, BUT ONLY ONCE. NOW, IT'S HAPPENING EVERY WEEK AND IT'S PRETTY ANNOYING. I'VE READ ON OTHER FORUMS WHERE PEOPLE ARE HAVING THE SAME PROBLEM. I'M AFRAID THIS IS GOING TO KILL MY BATTERY SOON.

THE PRESSURE OR HEAT COMING FROM MUFFLER BURNT BACK PART OF VEHICULAR I AM PAYING 1400.00 IN WIRE REPAIRS. AIR BAGS RECALL, SCARS ME DON'T HAVE ANOTHER CAR.THE PASSENGER DOOR AIR NOISE ESCAPING,MELTING DASH BOARD, ALARM SYSTEM GOES OF EVERYDAY UP TO 3TO 4 TIMES. TIRE PRESSURE, AND ENGINE LIGHT ON.

TL* THE CONTACT OWNS A 2009 MAZDA 6. THE CONTACT STATED THAT THE HORN ACTIVATED ALONG WITH THE DOOR ACTUATORS FAILING INTERMITTENTLY. THE CONTACT USED THE KEY FOB TO TURN OFF THE ALARM BUT IT FAILED TO REMEDY THE FAILURE. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER. THE TECHNICIAN REPLACED THE DOOR ACTUATOR FOR THE DRIVERS SIDE DOOR. HOWEVER, THE FAILURE RECURRED. THE VEHICLE WAS TAKEN BACK TO THE AUTHORIZED DEALER WHO INDICATED THAT THE FRONT DRIVERS SIDE AND THE REAR DRIVERS SIDE DOOR ACTUATORS NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 65,000.

THE CAR'S ALARM SYSTEM WOULD BE TRIGGERED RANDOMLY. IN A PERIOD OF 3 WEEKS IT HAPPENED AROUND 15 TIMES. IT ENDED UP DRAINING THE CAR BATTERY ONCE. THE ALARM IS ON FOR FEW SECONDS AND THEN IT STOPS BY ITSELF. UPON TAKING IT TO THE MAZDA DEALER THEY SAID IT IS A PROBLEM WITH DOOR'S ELECTRICAL SYSTEM AND THEY HAD TO REPLACE THE SWITCHES IN ALL 4 DOORS. THEY WERE ABLE TO SOLVE THE PROBLEM, BUT I DOUBT IF IT IS RELATED TO THE RECALL THAT WAS MADE LAST SEPTEMBER FOR FIXING THE DOOR'S LATCH SYSTEM. THE DEALER HAD FIXED THE SAME JUST A BACK MONTH. *TR

MY CAR ALARM HAD BEEN GOING OFF SPORADICALLY FOR ABOUT A YEAR OR MORE (MAYBE ONCE A MONTH), BUT IT GOT PROGRESSIVELY WORSE TO THE POINT THAT IT WOULD GO OFF 3-5 DAYS A WEEK. I'D HAD MY DOOR LATCHES INSPECTED AT THE END OF 2013 FOR A RECALL THAT ALTHOUGH IT WASN'T ELECTRICAL IN NATURE, ELECTRICAL ISSUES COULD DEVELOP IF IT'S NOT REPAIRED. SO, I WAS NOT EXPECTING THERE TO BE ANY ISSUES WITH THEM, BUT WAS SURPRISED TO LEARN THAT NOT ONE BUT BOTH OF MY REAR DOOR ACTUATORS WERE DEFECTIVE. AFTER GETTING THAT FIXED THE VERY DAY I PICKED UP MY VEHICLE FROM GETTING REPAIRS I NOTICED MY PASSENGER SIDE DASHBOARD WAS SHINY, AND APPEARED TO HAVE BEEN POLISHED. I LATER LEARN THAT LOOK ACTUALLY CAME FROM THE DASHBOARD MELTING. NOW I HAVE MELTING TOXIC MATERIAL, THAT ALSO CAN CAUSE A GLARE, IN MY VEHICLE. *TR

DRIVING THROUGH A TUNNEL MY CAR BEGAN TO FILL WITH SMOKE. I PULLED OVER AND LOOKED FOR WHERE THE SMOKE CAME FROM AND FOUND THE SWITCH TO MY HEATED SEATS WAS ON FIRE. MY CAR WOULD NO LONGER TURN ON. REPAIR MAN AT DEALERSHIP SAYS IT'S SOMETHING THAT JUST HAPPENS I GUESS. SOMEWHERE SOMETHING SHORTED. I'M JUST GLAD MY CHILD WAS NOT IN THE CAR WHEN THIS HAPPENED. BEWARE!! THERE ARE CURRENT RECALLS FOR THE EXACT MAKE AND MODEL IN AUSTRALIA AND EUROPE FOR THE SAME ISSUE. I'M STILL WAITING FOR THE US THE ISSUE A RECALL SO I CAN GET MY MONEY BACK.

2009 MAZDA6. CONSUMER WRITES IN REGARDS TO AUTOMATIC UNLOCK BUTTON MALFUNCTION. *SMD THE CONSUMER STATED WITHIN THE LAST YEAR, THE AUTOMATIC UNLOCK BUTTON INSIDE THE VEHICLE, SUDDENLY STOPPED WORKING, AND IN FACT DID THE OPPOSITE OF WHAT IT WAS SUPPOSED TO DO. WHEN THE UNLOCK BUTTON WAS PRESSED, THE ENTIRE VEHICLE AUTOMATICALLY LOCKED, AND AT TIMES, WOULD NOT RELEASE THE LOCK, EVEN MANUALLY. IT WOULD TAKE MANY ATTEMPTS AT PERFECT TIMING TO SELECT THE UNLOCK BUTTON WHILE OPENING THE DOOR IN ORDER TO BE ABLE TO GET OUT OF THE VEHICLE. THE AUTOMATIC LOCK BUTTON FUNCTIONED AS IT SHOULD, LOCKING ALL DOORS. IN OTHER WORDS, BOTH THE AUTOMATIC LOCK AND UNLOCK BUTTONS ONLY LOCKED THE DOORS. THE CONSUMER STATED SHE WAS LOCKED INSIDE THE VEHICLE ON SEVERAL OCCASIONS, UNTIL SHE WAS ABLE TO GET THE DOOR TO RELEASE. THE DEALER IDENTIFIED THE PROBLEM AS THE BODY CONTROL MODULE FOR THE LOCKS. HOWEVER, THEY COULD NOT OFFER A GUARANTEE THAT THE NEW BODY CONTROL MODULE WOULD NOT HAVE THE SAME PROBLEM, AS MAZDA ACKNOWLEDGED A PROBLEM WITH THE PART.
