2007 Mazda Mazda3 Electrical System Problems

Radio stopped working.

MY VEHICLE FELT SHAKY WHICH CAUSED ME TO SWERVE SLIGHTLY CAUSING MY BACK PASSENGER TIRE TO RUN OVER A CURB. AFTER THE SCARE IT SEEMED TO DRIVE LIKE NORMAL. I ONLY HAD ABOUT A 5 MINUTE DRIVE TO WORK. WHEN GETTING TO WORK, AFTER BEING INSIDE A FEW MINUTES, A COWORKER POINTED OUT THAT SMOKE WAS COMING FROM THE CAR. I WENT WITH A COWORKER TO CHECK, WE OPENED THE HOOD AND FLAMES WERE PRESENT IN THE FRONT CLOSE TO WHERE THE BELTS ARE. WE QUICKLY PUT OUT THE FLAMES WITH A FIRE EXTINGUISHER, AND I HAVE NOT TOUCHED THE VEHICLE. THIS HAPPENED ON 5/03/19.

SINCE WE HAD THIS CAR, WE'VE HAD TO REPAIR THE ENGINE OXYGEN SENSOR AT LEAST 2 TIMES. WHY THIS CONTINUES TO MALFUNCTION WE DON'T KNOW, BUT AT SOME POINT WE SHOULDN'T HAVE TO PAY FOR A FAULTY ENGINE/ELECTRICAL SYSTEM PART.

THE BRAKE LIGHT HOUSING (AMBER LENS) WAS HEATED BY THE BULB TO SUCH A DEGREE THAT THE LENS ITSELF MELTED ONTO THE BULB. WE ARE NOT ENTIRELY SURE WHEN THIS HAPPENED AND MAY HAVE BEEN ONGOING FOR QUITE SOME TIME. UPON INSPECTION BY AN EXPERIENCED AUTOMOTIVE TECHNICIAN, IT WAS CONFIRMED THAT THE BULBS WERE THE CORRECT MODEL AND HAD BEEN INSTALLED CORRECTLY. SOME OF THE PLASTIC HAD MELTED DOWN ONTO THE BULB ITSELF AND COULD POTENTIALLY BECOME A FIRE HAZARD. THIS PROBLEM IMPACTED BOTH DRIVER AND PASSENGER SIDES, WITH THE DRIVER SIDE APPEARING MORE SIGNIFICANTLY MELTED. AFTER A QUICK SEARCH ON MAZDA FORUMS, THIS APPEARS TO BE AN ISSUE EXPERIENCED BY MANY OWNERS OF 2007 MAZDA 3 MODELS, BUT ONLY THOSE IN THE HATCHBACK CONFIGURATION. *TR

THERE IS AN ISSUE WITH THE REAR BRAKE LIGHT ASSEMBLY, THE RED PLASTIC ASSEMBLY MELTED INTO THE BREAK LIGHT BULBS CAUSING BOTH REAR BRAKE LIGHTS TO BURN OUT. CURRENTLY, BOTH ASSEMBLY HAVE HOLES WHERE THE RED PLASTIC MELTED, THIS IS A POTENTIAL FIRE HAZARD. THERE IS AN ISSUE WITH THE FRONT PASSENGER SIDE ENGINE MOUNT, IT HAS BEEN REPLACED THREE TIMES AND CONTINUES TO FAIL, MIGHT AN ENGINEERING DEFECT ON THE ENGINE MOUNT. FINALLY, DASHBOARD AIRBAG INDICATOR HAS TURNED ON UNEXPECTEDLY AND HAS REMAINED ON EVER SINCE, MIGHT BE DEFECTIVE PART IN THE SRS AIRBAG SYSTEM. *TR

POWER WINDOW CONTROL ISSUE ON DRIVER'S SIDE ONLY - THE DRIVER'S POWER WINDOW BUTTON WILL WORK FOR AWHILE AND THEN INTERMITTENTLY STOP WORKING FOR A DAY OR SO. IT WILL RANDOMLY START WORKING AGAIN. NOT SURE IF IT HAPPENS MORE WHEN IT RAINS. I DID SEE THAT GM JUST PUT A RECALL DESCRIBING THE EXACT SAME THING I'M EXPERIENCING AND WAS WONDERING IF IT MIGHT BE THE SAME ISSUE...THEY DESCRIBE IT AS MOISTURE ENTERING THE DRIVER'S WINDOW RESULTING IN THE POWER CONTROL NOT WORKING INTERMITTENTLY. IT FIRST STARTED HAPPENING IN MY CAR ABOUT BACK IN MAY, BUT IT MIGHT HAVE BEEN EVEN LONGER. *TR

EVERY 3 MONTHS FRONT HEADLIGHT ARE REPLACED. *TR

I HAVE CONSTANTLY REPLACED MY DRIVER WINDOW MOTOR. THE DRIVER WINDOW SWITCH/MOTOR STOPS WORKING FOR NO REASON. IN ADDITION THE ENTIRE HEADUNIT STOPS WORKING. IT SHUTS ON AND OFF WHILE IN THE MIDDLE OF DRIVING. SOMETIMES TO POWERS RIGHT BACK ON AND OTHER TIMES IT CAN TAKE DAYS FOR IT TO TURN BACK ON. *TR

2007 MAZDA 3 INSTRUMENT PANEL GAUGES ARE VERY HARD TO READ IN BRIGHT DAYLIGHT. THE SPEEDOMETER IS MY MAIN PROBLEM.*AK
