2012 Mazda Mazda3 Problems

Car started jerking and on the way home, the car lost all power to the transmission. The check engine light came on as well as the AT and traction lights. Absolutely no power to the transmission. codes P0780 and P0751.

The car started to stall, hesitate and even stop completely for no apparent reason. The mechanic first recommended a new ECU/TCU which did not help the problem and in the course of duplicating the problem check engine light has come on for the transmission with problems shifting/sticking in a gear and not returning to first gear. My mechanic has stated that there is a known problem with Mazda3 transmission, and I should reach out to Mazda. They indicate there is no recall, but mechanic provided me TSB reference number 0500814 from a service bulletin. The car is a death trap and I have stalled while driving on the streets and freeway so obviously I can't drive the car. The car is still at the mechanics since parts cannot be found. Please help any way possible. Thank you.

MOTOR CYLINDER #1 LOW COMPRESSION TOOK IT TO MAZDA THEY COULDNT FIGURE IT OUT AND LESS THAN 20 MILES AFTER THE MOTOR THREW A ROD AT 70,001 MILES TOTAL. CYLINDER 1 WALLS WHERE NOT MADE CORRECTLY

WHEN I DRIVE DOWN THE ROAD.MY CAR SPEEDS UP AND I DON'T PRESS ON THE EXCILERATOR ANY HARDER. THE CARS IDOL GOES UP AND DOWN WHEN DRIVING AND AT PARK. THIS HAPPENS ON ALL TYPES OF ROAD WAYS. SOMETIMES IT SPEEDS UP ON ME SO FAST I HAVE TO HIT THE BRAKE WHILE DRIVING ON THE ROAD.

I can be turning left from a full stop and a few times almost went up onto the median seperating traffic. The car doesn't keep straight in it's own lane unless i put a lot of pressure with both hands on steering wheel and that doesn't always keep it straight, it veers left and right going down the road. Tire pressure light keeps coming on. when backing up hear like a grinding sound in passenger front tire. I bought this used at a Ford car dealership in June 2021. thats all i can think of right now. This has happened more than once no just one time.

I APPLIED THE BRAKES, AND THE CAR KEPT MOVING FORWARD EVEN THOUGH I WAS PRESSING THE BRAKE PEDAL. I PULLED THE EMERGENCY BRAKE BUT THAT DIDN'T STOP THE CAR FROM MOVING FORWARD AND HITTING THE BACK OF THE TRUCK IN FRONT OF ME. I WAS ON A HIGHWAY.

2012 Mazda3i 5dr hatchback. Persistent issue with headlights, both low beam and high beam, as well as interior lighting and other lighting. The headlights flicker for several seconds any time the brake pedal is applied. Interior lighting also flickers when brake pedal is applied. Headlights sometimes flicker when vehicle is decelerating and no brake pedal is applied, most notable when vehicle is traveling downhill. Further, the luminosity (brightness) of the headlights visibly dims, but does not flash, when the vehicle is parked and the brake pedal is applied. A high volume of others report the same issue, including documented complaints. These vehicles are unsafe, defective as designed, and do not conform to FMVSS No. 108. NHTSA must investigate further. Many other owners are not aware of the cause of the issue and attempt to fix it by replacing headlights, alternator, etc. Mazda was aware of issue prior to July 2013, when it issued TSB 01-019/13. This document states, "Some vehicles may exhibit the headlights flickering when the vehicle is decelerating (by applying the brakes) with the headlights on. This concern is caused by inadequate alternator output (controlled by the PCM) when the battery is under a heavy load. To correct the problem, the control logic of the PCM has been changed." This appears to be at best a temporary fix. Bommarito Mazda in Missouri required payment of $199.88 to "diagnose" this problem and address it in the manner prescribed in TSB 01-019/13. This service was not covered under warranty. Service Manager M.D. claimed to have never heard of this issue before and that it would need to be diagnosed, despite being informed by the owner of the precise issue, that others reported experiencing the same issue, and that others reported the issue was addressed by reprogramming the PCM. Immediately following this service, the headlights continued to visibly dim when the vehicle is parked and the brake pedal applied.

Headlight flickering and turns off and on randomly.

The car leaks gas when the tank is full and if the car is inclined slightly. I've noticed the problem several month ago with an occasional odor but finally saw the gas leaking recently when it was parked on a sloped street.

Our fuel tank is leaking for no reason. Brought it in last year (2024) for state inspections and let them know we smell gas when we park sometimes. They poke around and find nothing, but note there is a faint gas smell and to bring it to the dealer. We take it to Mazda to see if they can fix, they find nothing and charge my wife $250. Fast-forward to a year later, go for the same state inspection and we get failed. Our mechanic says theres a noticeable gas leak from the fuel tank and to take it to Mazda. There is clearly some issue with the fuel tank parts. The car itself only has 77k miles and it is 13 years old.

The contact owns a 2012 Mazda Mazda3. The vehicle was transported from the east to Texas, and the vehicle was bought used. The contact stated that the dashboard was sticky and that a gap was between the instrument panel and cover. The contact stated that a small to medium bubble had started to form. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 100,000. The VIN was not available.

The Seat Lifter on the driver's side seat frame broke, the metal has a clear stress fracture right near the bracket where the frame connects to the rail. This is the same part that was recalled in the 2010 and 2011 Models by Mazda in 2017. NHTSA Campaign No. 17V-082 It causes the driver side seat to change positions while driving creating hazardous conditions and does not appear structurally stable if involved in an accident potentially putting the driver's life at risk.

Passenger side door airbag is open

The dashboard of my 2012 Mazda 3 has separated from the instrument panel causing a gap between them. The dashboard has become very sticky leaving a black sticky film on the surface. This has caused a glare on the windshield making it hard to see at times while driving. There is a letter dated May 2017 from Mazda, Special Service Program (SSP) A9. The letter states that the warranty was extended 7 years (84 months) from the original warranty start date or April 30, 2018, whichever is later, with no milage limitation. As I read it, 7 years of 84 months from 2018 should extend the warranty for repair of replacement through 2025. Mazda refuses to make repairs, or replacement of this equipment that has an impact on the proper function of the airbag system and impairs the driver's vision because of the constant windshield glare. This is an issue. that needs to be addressed as an important safety.

my power steering has randomly failed for a second time. It happened once before as I pulled into a store -this time it happened while I was travelling southbound on highway 1 a very curvy road with steep cliffs where the speed limit is 55 so it was very scary when my steering suddenly went to manual steering. Turning the car off and waiting a few minutes seemed to remedy it. I continued to have a check engine light which cleared the next time I turned the car off. The power steering pump is an electric hydraulic pump so no belts involved. No weird noises just sudden scary failure. I researched on Mazda forums and found quite a few others with similar complaints and having spent money on dealers with no resolution. The car has 65k on it. The mfr does not have a change cycle for the fluid and I have verified the fluid clean. I did install a new battery and cleaned the ground on the terminal for the power steering pump as it seemed to help someone else. Mazda of course wants to take it and charge me to diagnose but based on other experiences with the dealer i do not trust them. Here is another person's similar story https://www.mazda3revolution.com/threads/power-steering-failure.108977/#post-1439705

TL* THE CONTACT OWNS A 2012 MAZDA 3. THE CONTACT STATED THAT THE REAR CAMBER WAS SET AT A NEGATIVE ANGLE, WHICH MADE THE REAR TIRES WEAR OUT. THE CONTACT STATED THAT ONLY THE INSIDE OF THE REAR TIRES MADE CONTACT WITH THE ROAD AND THE DESIGN WAS SET UP FOR RACING RATHER THAN NORMAL DRIVING. AN UNKNOWN DEALER STATED THAT NOTHING COULD BE DONE ABOUT THE DESIGN. THE MANUFACTURER WAS CALLED AND THE CONTACT WAS SUPPOSED TO CALL THEM BACK WITH THE VIN. THE FAILURE MILEAGE WAS 15,000. THE VIN WAS UNKNOWN.

I RECENTLY HAVE BEEN EXPERIENCING VISIBILITY ISSUES WITH MY 2012 MAZDA 3 SEDAN. IT STARTED WHEN THE PLASTIC INTERIOR ABOVE THE STEERING WHEEL BECAME "GOOPY" AS IT HEATS UP FROM THE SUN. IT IS IMPOSSIBLE TO REMOVE AND HAS LEFT BEHIND A SHINY SURFACE THAT REFLECTS ON THE WINDSHIELD IN FRONT OF MY DRIVING PERIPHERAL. I'VE RESEARCHED THIS ISSUE AND HAVE FOUND RECALLS FOR OTHER YEARS OF MAZDA MAKES/MODELS, BUT NOT MINE. THERE IS NOTHING I CAN DO AND IT'S BECOMING WORSE MAKING IT SO I CAN BARELY SEE OUT MY FRONT WINDSHILD ON BRIGHT, SUNNY DAYS. PLEASE LET ME KNOW IF THIS ISSUE CAN BE RESOLVED IN ANYWAY AS IT AFFECTS MY EVERYDAY LIFE AND IS BECOMING MORE AND MORE DANGEROUS TO DRIVE, ESPECIALLY WHEN THE SUN IS AT HIGH NOON. I HAVE ATTACHED SOME PHOTOS TO SHOW HOW THE INTERIOR PANEL HAS BECOME NATURALLY. IT'S CURRENTLY A CLOUDY DAY SO THE GLARE ISSUE IS NOT SHOWCASED AS MUCH. I HAVE TEMPORALLY LAID A TAN CLOTH OVER TO REDUCE SOME OF THE GLARE BECAUSE IT'S LESS SHINNY THAN THE MELTED INTERIOR (WHICH SEEMS TO REDUCE THE GLARE PROBLEM BY 50%). THANK YOU FOR LISTENING AND I HOPE TO HEAR BACK SOON.

THE CLEAR COAT WAS NOT PROPERLY APPLIED DURING MANUFACTURING OF THE VEHICLE LEADING TO EXTENSIVE PAINT LOSS AND CORROSION BEGINNING ON THE ROOF OF THE VEHICLE AND HOOD. EVENTUALLY THE FAILURE OF THE PAINT WILL LEAD TO RUST AND CORROSION OF THE ROOF AND SUPPORT SYSTEM OF THE VEHICLE WHICH CAN CAUSE BODILY HARM IF THE VEHICLE IS INVOLVED IN AN ACCIDENT.

The brake pedal is soft and sometimes unresponsive unless it is pumped repeatedly. There have been several times where I have been concerned if I would come to a complete stop. I have had both sets of brake pads replaced in the last year, and have on driven 9,000 miles. Two independent service centers diagnosed the problem as a faulty master cylinder. However, upon replacing the master cylinder and doing three brake flushes, and inspecting my brake pads and calipers, the problem persisted and is unresolved. They directed me to order a new ABS module, believing that that is the only other part that could be causing the cars brake problems. This part (BFY1437AZCO) is on backorder until November 2025.

Weak braking and spongy brake pedal created near accidents at highway speeds. Brake pedal needs to be pumped to get firmness. But the check engine warning light did not come on, either. So I had mechanics replace front rotors, front disc pads, and bleed/refill system with fresh brake fluid and inspect system for leaks. But spongy brake pedal problem was not fixed. So when I researched the problem on the internet, it appears that it's a systemic, long-time (10 model years or more) safety issue with Mazda that they failed to recall nationwide. Totally irresponsible. Among Mazda owners, after replacing all other brake system components and not solving the spongy brake pedal issue, it turned out to be a faulty ABS System Module, a $2,000 to $3,000 repair at Mazda dealerships.

MY WIFE WAS DRIVING HER VEHICLE AND THE FRONT CV AXLE COMPLETELY SNAPPED IN HALF. STILL NOT SURE WHAT COULD HAVE POSSIBLY OCCURED BEING THERE IS NO ACCIDENT REPORT ON THIS VEHICLE. PERHAPS THE PART WAS CORRODED OR FAULTY.

THE REAR SHOCKS HAVE AN UPPER ATTACHMENT THAT IS MADE OUT OF ALUMINUM. AFTER ONLY 49000 MILES THE SHOCK MOUNT CORRODED AND BROKE. IT ALSO CAUSED THE SHOCK ROD TO BEND.

RAN CAR INTO SIDE FENCING PUT UP FOR CONSTRUCTION IN REGARDS TO DODGING DEBRIS ON I295 FROM CONSTRUCTION WORK. MY TIRE BLEW OUT FROM HAVING TO RUN INTO THE GUARD RAIL AND I HAD TO PUT A DONUT TIRE ON. I BELIEVE THIS INCIDENT IS CORRELATED TO THE CONSTRUCTION WORK GOING ON FOR MONTHS NOW AND THAT I SHOULD BE REIMBURSED A NEW TIRE AND RIM FOR MY 2012 MAZDA 3/

TOOK VEHICLE IN FOR TIRE ROTATION. NOTICED LOUD HUMMING NOISE IN FRONT TIRES AFTER ROTATION. TOOK CAR BACK TO MECHANIC TO LOOK AT IT. I WAS TOLD THE FRONT TIRES WERE CUPPED BUT WOULD POSE NO PROBLEM FOR DRIVING. GAS MILEAGE HAS GONE DOWN 2 MPG SINCE THEN. *TR

TL* THE CONTACT OWNS A 2012 MAZDA 3. THE CONTACT STATED THAT THE DRIVER'S SEAT BELT FAILED TO RETRACT. THE VEHICLE WAS TAKEN TO NELSON MAZDA MURFREESBORO (1214 FORTRESS BLVD, MURFREESBORO, TN 37128) WHERE IT WAS DIAGNOSED THAT AN UNKNOWN PART IN THE SEAT BELT RETRACTOR NEEDED TO BE REPLACED. THE CONTACT WAS INFORMED THAT SHE WOULD HAVE TO PAY FOR THE REPAIR. THE MANUFACTURER WAS NOTIFIED AND DID NOT ASSIST. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 91,000.

TL* THE CONTACT OWNS A 2012 MAZDA 3. WHILE DRIVING 55 MPH, THE CLUTCH FAILED ON THE HIGHWAY. THE CONTACT STATED THAT THE REVOLUTIONS PER MINUTES DIAL FLUCTUATED RAPIDLY. THE CONTACT WAS ABLE TO CONTROL THE VEHICLE AND PARK. THE CONTACT STATED THAT THE CLUTCH WAS REPLACED FOUR TIMES FOR THE SAME FAILURE. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS TOWED EACH TIME THE FAILURE OCCURRED. THE VEHICLE WAS TAKEN TO JOHN HINE MAZDA (45 CAMINO DEL RIO S, SAN DIEGO, CA 92108 (888) 714-7925) WHERE IT WAS DIAGNOSED THAT THE CLUTCH FAILED DUE TO DRIVER ABUSE. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS CONTACTED AND STATED THAT THEY WOULD NOT ASSIST. THE FAILURE MILEAGE WAS 10,000.

APPROXIMATELY TWO OR THREE TIMES A WEEK WHEN DOWNSHIFTING OUT OF A RIGHT OR LEFT HAND CURVE OR TURN, MY 2012 MANUAL TRANSMISSION MAZDA 3 HATCHBACK WILL ACCELERATE ON ITS OWN. THIS IS CHARACTERIZED BY A VARYING INCREASE OF RPMS: 2100 RPMS TO 4500 RPMS, DEPENDING ON THE INCIDENT, AND A SUDDEN LURCHING OR SURGING FORWARD OF THE VEHICLE ITSELF. WHEN APPROACHING CURVES OR TURNS, AT 30 OR 40 MPH, THAT DO NOT HAVE TO BE TAKEN AT A COMPLETE STOP, I ENGAGE THE CLUTCH, APPLY THE BRAKES, AND SLOW THE VEHICLE TO 15-20 MPH. UPON COMING OUT OF THE TURN I SHIFT THE VEHICLE INTO SECOND GEAR. WHEN I SLOWLY RELEASE THE CLUTCH, WITHOUT DEPRESSING THE GAS PEDAL AT ALL, THE CAR'S ENGINE WILL REV, RPMS WILL SURGE TO AS HIGH AS 4000 - 4500, AND THE CAR WILL LURCH FORWARD UNTIL THE CLUTCH IS ONCE AGAIN DEPRESSED. THESE INCIDENTS ARE RANDOM AND ARE NOT DEPENDENT ON SPEED, WEATHER CONDITIONS, OR LOCATION. THESE INCIDENTS HAVE ONLY BEEN DUPLICATED WITH A MINIMAL INCREASE OF RPMS AND NO LURCHING FORWARD WHEN A MECHANIC IS PRESENT. THESE INCIDENTS CAN NOT BE DUPLICATED FOR THE DEALERSHIP AT THEIR FULLEST AND MOST DANGEROUS. *TR
