2014 MAZDA MAZDA3 Vehicle Speed Control Problems

While accelerating onto a highway, my engine overheating light flashed then stayed on and my acceleration suddenly throttled back and my car started slowing down. I was able to pull over on the shoulder, but there was a close call with a semi bearing down. I had my car towed to a repair shop, where they told me the water jacket had cracked and the overheating caused a blown head gasket. This was repaired and tested. A week later, I got the car up to highway speeds and the engine overheating light flashed again. When I stopped and looked at the engine, there was foamy tan coolant all over the place. Towed it back again and was told the weld had failed. But in trying to find a used cylinder to replace mine, the shop told me that all of their sources said they had no used ones available because...

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 TRUCK DRIVER TOOK SOME TO SHOW TO THE INSURANCE ADJUSTER.

MOMENTS AFTER DRIVING MY 2014 MAZDA 3, I NOTICED THE BLUE COOLANT DASHBOARD ICON WAS LIT SIGNALING THE COOLANT IS COLD. AS I DROVE WITHOUT TOUCHING THE ACCELERATOR, THE CAR ABRUPTLY ACCELERATED AND I HAD TO SLAM ON THE BRAKES SO I WOULD NOT REAR END THE CAR IN FRONT OF ME. PLUS, I NOTICED THE COOLANT DASHBOARD ICON TURN OFF ALSO. THE CRUISE WAS COMPLETELY OFF!

7/27/16 3:30 PM WEATHER CLEAR AND DRY ' TEMPERATURE 78 DEGREES MILEAGE ABOUT 24,000 ALL REGULAR MAINTENANCE UP TO DATE I ACCELERATED ONTO WASHINGTON SR 520 EASTBOUND AT EXIT 51 TO GET UP TO MERGING SPEED. I KEPT THE CAR IN SECOND GEAR AND THE ENGINE REVVED TO ABOUT 5,000 RPM. I DON'T THINK I HAVE EVER DRIVEN THE CAR OVER 4500 RPM IN THE NEARLY 3 YEARS I HAVE OWNED IT. I AM NOT SURE WHY I DIDN'T SHIFT INTO THIRD AS I USUALLY DO. THIRD GEAR IS MY DEFINITELY MY PREFERRED GEAR FOR THIS MANEUVER AND IT ALWAYS WORKS WELL FOR MERGING ONTO A HIGH SPEED HIGHWAY. I WAS GREETED WITH MULTIPLE FLASHING IDIOT LIGHTS FOR ENGINE, TIRE PRESSURE AND ANTI-SKID. THE THROTTLE WAS UNRESPONSIVE AND I WAS NOT ABLE TO MERGE ONTO THE HIGHWAY SAFELY AS MY SPEED DROPPED RAPIDLY FROM ABOUT 45 TO 30. I LIMPED...

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. ALL OF THIS HAPPENED IN 2 TO 3 SECONDS. WE WERE NOT HURT. THE EYE WITNESS WAS IN HIS YARD, WHICH ADJOINS THE TURN-AROUND AREA. AFTER THE ACCIDENT, HE CAME OVER AND ASKED IF I WAS OK. HE ASKED ME IF I COULD TURN MY...

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 IT.

TL* THE CONTACT OWNS A 2014 MAZDA 3. WHILE DRIVING AT APPROXIMATELY 50 MPH, THE SPEEDOMETER DECREASED TO ZERO AND THE ACCELERATOR PEDAL WAS DEPRESSED BUT THE VEHICLE DID NOT ACCELERATE. ALL OF THE WARNING LIGHTS ILLUMINATED. THE FAILURE RECURRED FOUR TIMES. THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 6,700.

MY MOTHER WAS DRIVING MY CAR ON THE LONG ISLAND EXPRESSWAY WITH 2 PASSENGERS IN THE CAR. SHE WAS DRIVING AROUND 60 MPH WHEN THE CAR SUDDENLY ACCELERATED BY ITSELF. IN A MATTER OF A FEW SECONDS THE CAR WENT FROM 60 MPH TO OVER 120 MPH. SHE TRIED PRESSING THE BRAKE PEDAL AS HARD AS SHE COULD BUT THE CAR WOULD NOT RESPOND. SHE HAD TO *JSDODGE ABOUT 7 CARS AS SHE TRIED TO GET THE CAR TO SLOW DOWN. SHE THEN PULLED THE EMERGENCY BREAK BUT THE CAR WAS MOVING SO FAST THAT IT BARELY SLOWED THE CAR DOWN. SHE GOT HER CAR TO THE SIDE (LAST LANE) OF THE HIGHWAY AND DECIDED TO PRESS THE PUSH TO START BUTTON AND THE CAR FINALLY CAME TO A HALT. THERE WAS NOT TOO MUCH TRAFFIC SO SHE WAS ABLE TO SURVIVE THE CARS SUDDEN ACCELERATION WITHOUT GETTING HURT OR...

IN ADDITION, THE VEHICLE DECELERATED. THE VEHICLE WAS TAKEN TO THE DEALER WHERE THE REPAIRS WERE UNKNOWN. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE AND CURRENT MILEAGE WAS 3,500.
