Mazda Motors North American Operations (Mazda) is recalling certain model year 2014-2016 Mazda3 vehicles manufactured January 4, 2014, to September 18, 2015. The fuel tank of the affected vehicles may have been improperly handled during manufacturing and, as a result, the welded attachment of the Inlet Check Valve (ICV) may fail and allow fuel to leak.
A fuel leak in the presence of an ignition source increases the risk of a fire.
Mazda will notify owners, and depending on the tank lot number, dealers will inspect the ICV weld, replacing the fuel tank, as necessary, free of charge. The recall began November 1, 2016. Owners may contact Mazda customer service at 1-800-222-5500. Mazda's number for this recall is 0116I.
Mazda North American Operations (Mazda) is recalling certain 2014-2015 Mazda6 and 2014-2016 Mazda3 vehicles. Water could possibly enter the brake caliper causing the parking brake actuator shaft to corrode and possibly bind.
If the parking brake actuator shaft binds, the parking brake may not engage or disengage fully. If the parking brake does not engage properly, the vehicle may move unexpectedly if it is parked on a slope, increasing the risk of a crash.
Mazda will notify owners, and dealers will check the parking brake actuator shafts, replacing any that are corroded, free of charge. Remedy parts are currently unavailable. Interim notices informing owners of the safety risk were mailed August 24, 2017. Owners will receive a second notice when remedy parts become available. Owners may contact Mazda customer service at 1-800-222-5500. Mazda's number for this recall is 1217F.
Mazda North America Operations (Mazda) is recalling certain model year 2014 Mazda3 vehicles manufactured June 12, 2013, through December 18, 2013, and model year 2014-2015 Mazda6 vehicles manufactured May 20, 2013, through December 4, 2013, and both equipped with a 2.5L engine and a regenerative engine braking system. When driving the affected vehicles in heavy rain or in deep puddles, the alternator belt may slip causing the Power Control module (PCM) to incorrectly assume failure of the charging system.
Once the PCM assumes that the charging system has failed, the vehicle will stop charging and could result in poor acceleration, loss of steering assist and windshield wiper operation, and a possible engine stall, increasing the risk of a crash.
Mazda will notify owners, and dealers will reprogram the PCM with updated software, free of charge. The recall began on May 19, 2014. Owners may contact Mazda at 1-800-222-5500. Mazda's number for this recall is 7314D.
Mazda North American Operations (Mazda) is recalling certain 2014-2018 Mazda3 and 2016-2021 CX-3 vehicles. The rearview camera image may not display properly by showing a flickering or distorted image.
A rearview camera that does not display properly can reduce the driver's rear view, increasing the risk of a crash or injury.
Dealers will inspect and replace the rearview camera, as necessary. In addition, dealers will install a wiring harness fastening seal. All repairs will be performed free of charge. Interim notification letters, notifying owners of the safety risk, were mailed September 13, 2023. Final owner letters for affected models and model years in the states of CT, MA, MD, NJ, NY, PA and VA were mailed August 14, 2024. The remaining owner notification letters will be mailed at a future date, anticipated on or before May 1, 2025. Owners may contact Mazda customer service at 1-800-222-5500, Option 6. Mazda's number for this recall is 6023G.

MY DAUGHTER WAS DRIVING AT 65 MPH ON THE INTERSTATE. THE ROAD WAS STRAIGHT AND SHE WAS TRAVELING IN THE RIGHT HAND LANE WHEN SHE WAS STRUCK FROM BEHIND LEFT OF CENTER BY ANOTHER VEHICLE. HER CAR BOUNCED OFF THE RIGHT SIDE GUARDRAIL AND THEN SPUN ACROSS THE ROADWAY. HER CAR THEN STRUCK THE CONCRETE BARRIER ON THE LEFT SIDE OF THE ROAD. MY DAUGHTER AND HER PASSENGER WERE THROWN BACKWARDS DUE TO THE IMPACT FROM BEHIND AND MY DAUGHTER LOST CONSCIOUSNESS AT THAT POINT. SHE SUFFERED A CONCUSSION AND HAS HAD FREQUENT AND SOMETIMES SEVERE HEADACHES, ALONG WITH BACK AND NECK PAIN SINCE THE ACCIDENT. TH
AS I WAS TURNING INTO A PARKING SPOT TO PARK MY CAR, THE CAR ACCELERATED ON ITS OWN AND RAN INTO A CONCRETE WALL. I HAVE HAD ISSUES WITH THIS CAR'S PROGRAMMING, INCLUDING WHEN I TOOK MY CAR IN TO GET FIXED AFTER THE SAFETY RECALL IN JANUARY '16. AS I REALIZED THE CAR WAS ACCELERATING - AND PUSHING ON THE BRAKE WOULD NOT STOP IT - I LIFTED THE EMERGENCY BRAKE. THE CRASH ULTIMATELY STOPPED THE CAR - NOT THE BRAKE OR EMERGENCY BRAKE, AND THE AIRBAG DEPLOYED. LESS CONCERNED ABOUT THE DAMAGE TO THE OUTSIDE OF THE CAR, AND MORE CONCERNED THAT I HAD ZERO CONTROL OVER THE CAR AND ANY ABILITY TO STOP
IN PARKING GARAGE, TURNING INTO PARKING SPOT. CAR ENGINE REVVED UP, AND CAR ACCELERATED INTO THE GUARD RAIL, SMASHING THE FRONTEND OF THE VEHICLE AND DAMAGING THE RADIATOR. DRIVER DID NOT PUT FOOT ON THE GAS; CAR LUNGED FORWARD ON IT'S OWN. THE AIRBAG DEPLOYED, AND DRIVER HAD DARK BRUISES ON ABDOMEN, LEFT ANTERIOR THIGH, AND LEFT SIDE OF NECK D/T SEAT BELT, AND ALSO HAD MINOR WHIPLASH. FORTUNATELY, NO OTHER CARS OR PEOPLE WERE AROUND WHEN CAR ACCELERATED. ALSO, HAD THE CAR HAD MORE THAN JUST A FEW FEET TO RUN INTO SOMETHING, THE DRIVER WOULD HAVE BEEN INJURED WORSE. PRIOR TO INCIDENT, C
I WAS DRIVING DOWN THE FREEWAY IN THE SNOW/RAIN MIX WHEN I HEARD A LOUD BANG! I THOUGH I WAS HIT BY ANOTHER CAR BUT WHEN I LOOKED AROUND I NOTICED THE GLASS OF MY SUNROOF HAD SHATTERED AND SOME GLASS FELL ON ME. UPON FURTHER INVESTIGATION, THE SUNROOF HAD ACTUALLY BLEW OUT AND UPWARDS FROM THE INSIDE OUT. I CONTACTED THE DEALERSHIP WHO THEN SUBMITTED A CLAIM TO MAZDA. ALTHOUGH THEY ARE AWARE OF LATENT DEFECTS IN SUNROOFS, THEY REFUSE TO REPAIR/REPLACE MINE. IT'S COLD AND RAINING HERE AND I HAVE PART OF MY CAR ROOF MISSING DUE TO A MANUFACTURERS DEFECT THAT I KEEP READING ABOUT ALL OVER THE IN
Today on 3/6/23 I was parked outside a restaurant picking up food as I was inside the restaurant my hand brake failed to hold and my car rolled back and hit another customers car. My car is a manual and I had it in neutral and I was then approached by the owner of the vehicle I hit asking for my insurance information.
ON NUMEROUS OCCASIONS WHEN I ATTEMPT TO ACCELERATE, THE VEHICLE DOES NOT MOVE FORWARD AND FEELS LIKE IT MIGHT BE JAMMED. THE CAR WILL THEN PROPEL INTO GEAR CAUSING MY VEHICLE TO SKID OUT. THE PROBLEM IS INTERMITTENT. IT APPEARS TO BE HAPPENING THE WORST WHEN MAKING RIGHT HAND TURNS. THIS HAS RESULTED IN ONE ACCIDENT, AND TWO NEAR FATAL ACCIDENTS.
I WAS TURNING SLOWLY INTO A PARKING SPACE BETWEEN TWO PARKED CARS WITH MY FOOT ON THE BRAKE. APPROXIMATELY 1/4 TO 1/3 OF THE WAY INTO THE SPACE THE CAR SUDDENLY ACCELERATED (MY FOOT STILL ON THE BRAKE). IT JUMPED THE CURB, CROSSED OVER THE SIDEWALK, "TOOK OUT" 2 PILINGS AND LARGE FLOWER BOX AND THEN STOPPED. ENGINE WAS STILL RUNNING. IT HAPPENED IN A MATTER OF SECONDS AND I HAD NO TIME TO REACT IN ANY WAY. CAR HAD TO BE WINCHED OFF OF THE PILINGS WHICH NOW HAVE TO BE RESET APPROX. 15" - 18" INTO THE GROUND. I HAVE PHOTOS TAKEN BY A NEIGHBOR, BUT DO NOT KNOW HOW TO UPLOAD THEM. TOW TRUC
MY 2014 MAZDA 3 SUDDENLY AND UNEXPECTEDLY ACCELERATED AND CRASHED INTO A PARKED TRUCK. THERE WAS AN EYE-WITNESS. HERE IS WHAT HAPPENED: I WAS DRIVING ON A QUIET, DEAD-IN STREET ACCOMPANIED BY MY HUSBAND. I TURNED LEFT INTO THE TURN AROUND AREA AT THE END OF THE STREET. AS I WAS COMING TO A STOP, WITH MY FOOT ON THE BRAKE, THE CAR SUDDENLY ACCELERATED'GOING VERY FAST, VERY QUICKLY. IT LEAPT OVER THE CURB, NARROWLY MISSED A TREE AND A FIRE HYDRANT, PASSED BACK OVER THE STREET I HAD BEEN ON MOMENTS EARLIER, AND CRASHED INTO A PARKED PICK-UP TRUCK. THE AIR-BAGS DID NOT DEPLOY.
