What 352 owners told NHTSA about the 2012 Hyundai Santa Fe Hev

WHILE DRIVING THE ENGINE WOULD DECELERATOR THEN CUT OUT. I CAN BE ON THE HIGHWAY GOING SPEED LIMITS OF 70 OR ON A SIDE STREET GOING 30 OR UNDER. IT EVEN HAPPENED WHEN I PULLED OUT OF MY DRIVE WAY AND DROVE DOWN MY STREET (4 HOUSES DOWN) AND GOT TO MY CUL-DE-SAC AND ALL POWER SHUT DOWN. NEIGHBOR HAD TO STOP TO AVOID HITTING ME BECAUSE I WAS ROLLING AND COULD NOT STOP. ALL POWER TO STEERING WHEEL AND BRAKES WOULD BE NON OPERATIONAL. I HAVE TO MANUALLY PULL THE WHEEL TO ONE SIDE TO AVOID TRAFFIC, CAUSING AN ACCIDENT, OR FROM BEING HIT BY HEAD ON TRAFFIC. THE FIRST OCCURRENCE WAS IN FEBRUARY OF 2017 AND THE MOST RECENT WAS JANUARY 18TH ON MY WAY HOME FROM WORK. IT HAS HAPPENED TO US OVER A DOZEN TIMES AND FOUND BLOGS THAT STATE THAT HYUNDAI DENIES THAT THIS IS HAPPENING.

AS EARLY AS LAST SUMMER, MY 2012 HYUNDAI SANTA FE STARTED TO (INTERMITTENTLY) ACCELERATE WHEN I STEPPED ON THE BRAKE. FRANKLY, I THOUGHT IT WAS RELATED TO THE SANDALS I WAS WEARING. I THOUGHT I WAS OCCASIONALLY STEPPING ON THE GAS AND THE BRAKE AT THE SAME TIME (I HAVE VERY BIG FEET -- SIZE FIFTEEN). THE PROBLEM STOPPED WHEN I SWITCHED SHOES (WHICH ALSO CORRESPONDED TO THE END OF SUMMER). THE PROBLEM CAME BACK INTERMITTENTLY THIS SUMMER AND IS NOW REPEATABLE. WHEN I AM GOING DOWN A STEEP HILL AT SPEEDS OVER ABOUT 20 MPH, THE ENGINE RPM'S INCREASE WHEN I STEP ON THE BRAKE. IT DOES THAT WHILE IN GEAR AND WHILE IN NEUTRAL. OBVIOUSLY, IF THE DRIVE TRAIN IS IN GEAR, THE ENGINE "FIGHTS AGAINST" THE BRAKE; IF THE DRIVE TRAIN IS IN NEUTRAL, THE ENGINE REVS. IF THE ENGINE IS IN NEUTRAL OR IS SHIFTED INTO NEUTRAL AFTER THE ACCELERATION STARTS, THE ENGINE RACES UNTIL I LET OFF THE BRAKE. IT HAS GONE AS HIGH AS 4-5 K RPM BEFORE I LET OFF THE BRAKE. ALL THAT'S REQUIRED TO GET THE CAR TO RETURN TO NORMAL IDLE IS THAT I PUMP THE BRAKE (LET OFF THE BRAKE ALL THE WAY -- I CAN IMMEDIATELY RE-APPLY THE BRAKE AND THE PROBLEM WON'T HAPPEN AGAIN). I HAVE IDENTIFIED A STRETCH OF ROAD NEAR MY HOUSE WHERE THE PROBLEM ALWAYS OCCURS. DRIVING EAST AT THE END OF WALNUT STREET AT THE INTERSECTION OF WALNUT AND BOSTON HILL CIRCLE, NEAR SOUTH STREET IN SHREWSBURY, MA 01545, IT PROBLEMS ALWAYS REPLICATES. IT ALSO ALWAYS HAPPENS AT THE BEND IN THE ROAD WHILE GOING DOWN HILL ON BOSTON HILL CIRCLE... UPDATED10/13/16 *BF ...VIDEO AVAILABLE *TR

TODAY APRIL 28, 2015, MY MOTHER, DAUGHTER AND I WERE COMING HOME FROM RUNNING AN ERRAND, WHEN WE CAME TO ARE HOUSE WE PULLED UP AND WENT IN REVERSE TO PULL INTO THE DRIVE WAY LIKE NORMAL SO WE CAN PARK THE CAR IN THE GARAGE. WHEN WE PULLED IN WE WERE GOING JUST 5MPH. THEN SUDDENLY WHEN MY MOM WAS PUSHING THE BRAKE THE STOP AND PUT THE CAR INTO PARK. THE CAR OUT OF NO WHERE LURCHED AND CRASHED INTO ARE WASHER, WATER HEATER , AND CAUSED THE BACK WINDSHIELD TO SHATTER. AN WE HAVE HAD THIS CAR FOR 3 YEARS AND ITS ALWAYS THE SAME ROUTINE, SO WERE VERY SHOOK UP ON HOW THIS COULD HAPPEN. EVEN THOUGH THIS HAPPENED AT A RESIDENT IM FILING THIS SINCE IT COULD HAPPEN ANYWHERE TO ANOTHER CAR. *TR

I WAS TURNING RIGHT INTO A PARKING SPACE, APPLIED THE BRAKES AND THE VEHICLE SURGED/ACCELERATED. IT WENT OVER A CURB AND HIT ANOTHER VEHICLE. WHEN IT STOPPED I LOOKED DOWN AND MY FOOT WAS INDEED ON THE BRAKES, TO THE FLOOR. A SIMILAR THING HAPPENED TWICE BEFORE. I WAS TURNING ONTO ANOTHER STREET AND THE CAR FELT LIKE IT SURGED. FORTUNATELY BOTH TIMES THERE WAS NO ONE IN THE OTHER LANE OR IN FRONT OF ME. *TR

I WAS STOPPED IN A LEFT TURN LANE AND I BELIEVE I WAS THE 8TH OR 9TH VEHICLE IN LINE. I HAD MY FOOT ON THE BRAKE PEDAL AND THE PEDAL WENT TO THE FLOOR! I TURNED MY STEERING WHEEL TO THE LEFT AS FAR AS I COULD, BUT I TAPPED THE BUMPER OF THE VEHICLE IN FRONT OF ME. THERE WERE NO INJURIES AND VERY MINOR DAMAGE TO THE REAR BUMPER OF THE VEHICLE IN FRONT OF ME, AND VERY MINOR DAMAGE TO MY FRONT BUMPER. NO OTHER VEHICLES WERE INVOLVED. I CALLED THE HYUNDAI DEALERSHIP AND TOLD THEM THAT MY BRAKES HAD FAILED AND HAD CAUSED AN ACCIDENT. I WAS TOLD THAT IT WAS PROBABLY NOT THE BRAKES, BUT THE MASTER BRAKE CYLINDER. I HAD THE VEHICLE TOWED TO THE DEALERSHIP (CARL GREGORY HYUNDAI, AT NORTHLAKE, COLUMBUS, GA) THIS MORNING I CALLED TO CHECK ON THE STATUS OF THE VEHICLE AND WAS TOLD THAT THEY HAD DRIVEN THE VEHICLE FOR 200 MILES AND COULD NOT REPRODUCE THE PROBLEM. I HAD ALREADY TOLD THEM THAT I WAS STOPPED IN A TURN LANE WHEN THE BRAKES FAILED!! I WAS TOLD THAT THE HYUNDAI REPRESENTATIVE TOLD THEM TO REPLACE THE MASTER CYLINDER. *TR
