I AM THE ORIGINAL OWNER OF THE VEHICLE, I COMPLAINED OF ENGINE SURGE ON SEVERAL VISITS TO MAZDA, AND THEY WOULD ALWAYS SAY THEY WERE UNABLE TO DUPLICATE THE PROBLEM. I WAS RECENTLY DRIVING THE VEHICLE WHEN IT ACCELERATED ON IT'S OWN, THE RPM'S WOULD FLUCTUATE BETWEEN 2 AND 4. THE VEHICLE ACCELERATED UNCONTROLLABLY, I HAD DIFFICULTY STOPPING AT STOP SIGNS AND TRAFFIC LIGHTS ON MY WAY TO MY MECHANIC. WHEN I REACHED HIS GARAGE I LEFT THE VEHICLE IN PARK TO SHOW HIM WHAT IT WAS DOING AND IT IDLED AT 3 RPMS. THE MECHANIC HAS NOT BEEN ABLE TO REPAIR THE VEHICLE. I HAVE RESEARCHED THE PROBLEM AND HAVE FOUND THAT OTHER MAZDA AND FORD VEHICLES HAVE HAD SIMILAR ISSUES. *TR
CONSTANT OVERHEATING PROBLEMS. CHANGED EVERYTHING FROM HOSES TO RADIATOR,THERMOSTAT AND GASKET BUT IT STILL COMES ON AFTER A WHILE. SPENT SOOO MUCH MONEY ON THIS AND THE OTHER DAY SMOKE ERUPTED FROM CAR WHEN DRIVING AND GOT IN ACCIDENT. FORMER OWNER HAD SAME PROBLEM. *TR
MY BATTERY ON MY 2004 MAZDA 6 WENT OUT AND I HAD TO JUMP START IT TO.GO TO WORK AND COME FROM WORK ONE DAY. THE NEXT DAY I TOOK MY BATTERY TO GET CHECKED TO SEE WHAT THE ISSUE WAS AND THEY TOLD ME MY BATTERY WAS COMPLETELY DEAD AND IT HAD ONLY 6 MONTHS OF USAGE. I PUT A NEW BATTERY IN MY VEHICLE AND AS I INSTALLED THE NEW BATTERY I UNPLUGGED IT TO SEE IF MY ALTERNATOR WOULD KICK IN TO MAKE SURE IT WAS WORKING CORRECTLY AND AS I PUT THE BATTERY BACK ON A SHORTAGE HAPPENS AND MY WIPERS CAME ON AT FULL SPEED AND ALL MY LIGHTS WERE BLINKING ON MY DASH AND A SMELL OF ELECTRICAL WIRES BURNING STARTED TO HAPPEN AND THE ENTIRE ELECTRICAL SYSTEM HAS MESSED UP. TURN SIGNAL LIGHTS DON'T WORK,HEADLIGHTS, BOSE STEREO,HAZARD LIGHTS,REVERSE LIGHTS TRUCK DON'T OPEN WINDOWS DON'T GO UP OR DOWN AND WHILE I DRIVE THE SPEEDOMETER DOES NOT TRACK THE VELOCITY THE NEEDLE GOES CRAZY AND MY E-BRAKE LIGHT IS ON AND TRACK CONTROL LIGHT IS BLINKING AND THE AIR BAG LIGHTS COME ON ALL THE TIME . I DO NOT KNOW WHERE TO START TO FIX THIS ISSUE BUT I'M REALLY DISAPPOINTED IN THIS BECAUSE I JUST HAVE 8 MONTHS WITH MY VEHICLE FROM A DEALER SHIP AND THEY CHECKED OUT CAR JUST FINE. THIS IS GOING TO BE A SUPER HIGH COST TO REPAIR ALL THE DAMAGES. JUST FROM A CHANGE OF A BATTERY. AND TO TOP IT ALL THANK GOD I WASN'T IN THE CAR BECAUSE THEIR WAS A SMALL FIRE IN THE WIRES BUT IT WENT AWAY QUICK. *TR
WHILE PULLING INTO A PARKING SPACE, THE BRAKES DISENGAGED, ALMOST CAUSING CONSUMER'S VEHICLE TO CRASH INTO OTHER VEHICLES. THE DEALER INSPECTED THE VEHICLE, AND STATED THAT THE BRAKES WERE NOT DEFECTIVE. *AK THE CONSUMER STATED THAT THE VEHICLE LUNGED FORWARD DURING THE INCIDENT. *SC *JB
I WAS ORIGINALLY MISQUOTED IN MY COMPLAINT TAKEN OVER THE PHONE SO I AM WRITING THIS AS A CLARIFICATION OF THE EVENT THAT OCCURRED. I OWN A 2004 MAZDA 6S. WHILE ENTERING A PARKING SPACE AT A SPEED NO MORE THAN 10MPH, THE BRAKES DISENGAGED FOR 2-3 SECS WHILE THE BRAKE WAS STILL BEING APPLIED. I WAS CERTAIN THAT THE CAR WAS GOING TO JUMP THE CURB, WHICH DID NOT HAPPEN. THE BRAKES RE-ENGAGED CAUSING MYSELF AND MY PASSENGER TO LUNGE FORWARD VIOLENTLY. UPON TAKING THE CAR TO A MAZDA SERVICE DEPARTMENT, THE CAR WAS TEST DRIVEN, THE BRAKING SYSTEM WAS CHECKED, AND FOUND TO WORK NORMALLY AT THE TIME OF SERVICING. *NM
