2009 Hyundai Santa Fe

WHEN SLOWING DOWN TO MAKE A TURN THE ENGINE SHUTS OFF. POWER STEERING AND BREAKS ARE GONE. THE CAR WILL CRANK RIGHT BACK OFF BUT THIS US VERY DANGEROUS. I'M NOT SURE IF WEATHER IS A FACTOR BUT WHEN IT HAS HAPPENED WHICH GAS BEEN MULTIPLE TIMES, IT HAS BEEN IN THE 80'S. MECHANICS AND DEALERSHIP HAVE NOT BEEN ABLE TO FIND ANYTHING AND NO CODES ARE RECORDED.

THIS HAS HAPPENED MULTIPLE TIMES OVER THE PAST YEAR AND HAS INCREASED IN FREQUENCY THE LAST 2 MONTHS. AT RANDOM TIMES, IN TOWN OR ON HIGHWAY WITH VARYING SPEEDS, THE RPM WILL JUMP WITHOUT ME USING ANY MORE PRESSURE ON THE GAS PEDAL, WHICH CAUSES THE CAR TO ACCELERATE QUICKLY AND WITHOUT WARNING. THEN, THE RPM WILL GO BACK DOWN IN THE SAME MANNER JUST AS QUICKLY.

WE WERE EXITING A RAMP OFF RT 75 IN FLORIDA. OUR SPEED WAS ABOUT 30 MPH. SUDDENLY WE LOSS POWER STEERING AND BRAKING AND ACCELERATION. WE COASTED TO A STOP. WE TURNED OFF THE IGNITION AND RESTARTED THE CAR AFTER ABOUT 2 MINUTES...EVERYTHING RETURNED TO NORMAL. IT WAS THE SECOND SUCH EXPERIENCE. THE FIRST WAS AUGUST 2013. THE DEALERSHIP REPLACED THE THROTTLE SENSOR AT THAT TIME. THIS LATEST EXPERIENCE IS THE EXACT DUPLICATE OF THE FIRST. I AM TAKING THE CAR TO THE DEALERSHIP TOMORROW MORNING.

I WAS PARKING MY CAR IN A SPACE AT A LOCAL STORE. THE CAR TOOK OFF. SUDDEN ACCELERATION. WENT FORWARD PROBABLY A GOOD 15 FEET BEFORE I WAS ABLE TO STOP. I ALSO HAD TO HAVE BOTH FUEL TANK SENSORS REPLACED. MY GAS GAUGE WOULD NOT REGISTER PROPERLY. FLUCTUATED UP AND DOWN AT RANDOM MOMENTS. COST ME $364.51! SEEMS TO BE A CONTINUING PROBLEM. *TR

VEHICLE SLOWED WITHOUT WARNING ON FREEWAY AT FREEWAY SPEED, THEN WOULD NOT ACCELERATE. WENT TO IDLE MODE. BEFORE SLOWDOWN, HAD MILD SURGING AT SPEED. PROBLEM WAS DIAGNOSED AT TPS OR THROTTLE POSITION SENSOR. PROBLEM WITH SAME SENSOR REPORTED TO HYUNDAI DEALERSHIP PREVIOUS, DIAGNOSED AS LOOSE CONNECTION REPORTED FROM PERIODIC SURGING WHILE DRIVING. AFTER RECENT PROBLEM WITH ALTERNATOR, WHICH REQUIRED REPLACEMENT OF PART, WITHIN ONE WEEK, TPS PARTIALLY FAILED. FAILURE WAS NOT DIAGNOSED AS KIA DEALERSHIP (SISTER COMPANY TO HYUNDAI) WHEN UNDERWENT FIRST REPAIR. FAILURE REQUIRED HYUNDAI DEALERSHIP TO BE TOLD EXACT PROBLEM, WHEREBY THEY CONFIRMED DIAGNOSIS. PART REQUIRED REPLACEMENT WITH SOFTWARE UPDATES. PART PROBLEM LEADING TO FAILURE SHOULD HAVE BEEN ABLE TO BE DIAGNOSED UNDER FIRST ROUND OF TESTING, AND UNDER FIRST REPAIR A WEEK PRIOR. PARTS UNPREDICTABLE FAILURE IS BELIEVED TO PRESENT A SIGNIFICANT RISK WHILE VEHICLE IS OPERATING. *TR

I ENTERED A LIMITED ACCESS HIGHWAY AND BEGAN TO ACCELERATE TO MERGE INTO TRAFFIC WHEN THE CAR BEGAN TO ACCELERATE WILDLY WITH NO CONTROL OVER SPEED. I TRIED TO BRAKE THE CAR BUT IT KEPT ACCELERATING. I PUT CAR IN NEUTRAL AND ENGINE WAS OVER-REVVING FRIGHTENINGLY SO I TURNED OFF THE IGNITION.I FELT THE ACCELERATOR PEDAL COME UP OFF THE FLOOR AND TAP THE SOLE OF MY RIGHT FOOT. AT THIS POINT I WAS ABLE TO GET TO THE SHOULDER AND PUT ON MY 4 WAY FLASHERS. I ESTIMATE MY TOP SPEED TO BE ABOUT 75 MPH DURING THIS INCIDENT. FORTUNATELY I DID NOT CONTACT ANY OTHER VEHICLES OR OBJECTS. MY WIFE WAS IN THE FRONT PASSENGER SEAT. AFTER A FEW MINUTES,I RESTARTED THE CAR AND IT BEHAVED NORMALLY. WHEN I REACHED HOME I CALLED THE DEALER AND SCHEDULED AN APPOINTMENT WITH THE SERVICE DEPARTMENT FOR THE NEXT BUSINESS DAY. *TR

I WAS LEAVING TO GO TO WORK, MY HUSBAND WALKED ME OUT OF OUR HOUSE SAYING GOODBYE, I WAS IN MY DRIVEWAY, TURNED MY WHEEL TO GO AROUND OUR OTHER CAR, WHEN ALL OF A SUDDEN THE SANTA FE FORCEFULLY ACCELERATED (NOT BY ME HITTING THE GAS ON ACCIDENT) HITTING MY HUSBAND THROWING HIM TO GROUND (WHICH HE IS A STURDY GUY) AN THEN HITTING MY OTHER CAR, IT WOULD NOT STOP I HAD BRAKE PEDEL DOWN AND PUT ON EMERGENCY BRAKE ON PUT IN REVERSE AND YET NOTHING JUST GOING FULL FORCE IN THE BACK OF MY OTHER CAR. I EVEN TOOK MY FOOT OFF THE BRAKE TO MAKE SURE IT WAS NOT THE GAS PEDEL. IT WAS SO SCARY I DID NOT KNOW IF MY HUSBAND WAS BEENING CRUSHED BETWEEN CARS. I WAS SO SCARED THAT MY KIDS WOULD COME OUT AND GET RAN OVER TRYING TO HELP. I TURNED OFF THE CAR (WISH I WOULD HAVE THOUGHT OF THAT SOONER) AND FINALLY AFTER PUSHING MY OTHER CAR AT LEAST 5 FEET IT FINALLY STARTED WINDING DOWN AND MAKING A LOUD HISSING SOUND. I FOUND MY HUSBAND LYING ON THE GROUND THANKING GOD I DIDNT KILL HIM . I CALL THE POLICE TO REPORT WHAT HAD HAPPEND, TOOK PICTURES OF ALL THE DAMAGE THAT THE SANTA FE DID. WE TOOK THE SANTA FE BACK TO DEALERSHIP STILL UNDER WARRENTY JUST PURCHASED 8 MONTHS AGO ONLY 63,000 MILES ON IT, THEY SAID NOTHING WRONG WITH THE CAR DID NOT WANT TO HEAR ABOUT WHAT HAPPENED. ONLY THING THEY SAID WAS POWERSTEERING LINE CRUSH AND WHATEVER DAMAGE DONE FROM THE INCIDENT, AND TRIED TO CHARGE ME $120.00. SO NOW ITS AT A HYUNDAI DEALERSHIP, BUT SEEMS NO ONE CARES WHAT HAPPENED. I AM VERY CONCERNED WITH THIS PROBLEM, WHERE I WORK I PARK IN A COLLAGE CAMPUS AREA WITH LOTS OF PEOPLE WALKING AROUND ALL THE TIME, I"M AT MY KIDS SCHOOL AT LEASE 8 TIMES A WEEK, WHAT IF THIS HAPPENS AT THE SCHOOLS? SO WORRIED THAT THEY WILL SAY ITS OKAY NOTHING WRONG,( WHICH ALREADY HEARD THAT!) BUT NEXT TIME MIGHT NOT BE SO LUCKY. NEED HELP PLEASE!!!! *TR
