2009 HYUNDAI SANTA FE Engine Problems

THE VEHICLE LOOSES ALL POWER. IT ALSO SURGES AND STALLS. *TR

WHILE DRIVING ON THE INTERSTATE AT APPROXIMATELY 70 MPH, USING CRUISE CONTROL, THE CAR SUDDENLY LOST POWER. I STEPPED ON THE GAS AND IT WOULD NOT ACCELERATE. I COASTED TO A STOP AND PULLED ONTO THE SHOULDER. THE ENGINE WAS RUNNING, TRANSMISSION WAS IN GEAR, BUT THE CAR WOULD NOT MOVE. I TURNED OFF THE IGNITION AND LET IT SIT FOR A FEW MINUTES. I RESTARTED IT, HAD POWER, EVERYTHING SEEMED NORMAL, EXCEPT THE ENGINE LIGHT REMAINED LIT. I DROVE APPROXIMATELY 10 MILES TO MY DESTINATION. THE CAR SAT FOR SIX HOURS AND I WAS THEN ABLE TO DRIVE THE 65 MILES HOME WITHOUT INCIDENT. REPAIR RESULTS: MY HYUNDAI DEALER INDICATED THE PROBLEM WAS CAUSED BY A 'THROTTLE POSITION SENSOR'. THEY REPLACED THE ELECTRONIC COMPONENT AND RESET THE ERROR CODES IN THE VEHICLE'S COMPUTER. *TR

I WAS DRIVING APPROXIMATELY FORTY (40) MILES PER HOUR, IN TRAFFIC, WHEN THE ENGINE SHUT-OFF. I QUICKLY TURNED THE IGNITION TO "OFF" AND THEN BACK ON. THE ENGINE STARTED IMMEDIATELY. I AM EXTREMELY CONCERNED ABOUT BEING IN AN ACCIDENT. THIS HAPPENED AGAIN, WHEN I WAS DRIVING THROUGH A PARKING LOT. I QUICKLY TURNED THE IGNITION TO "OFF" AND THEN BACK ON. THE ENGINE STARTED IMMEDIATELY, ON BOTH OCCASIONS. I TOOK MY VEHICLE INTO PLANET HYUNDAI IN LAS VEGAS, NEVADA, ON AUGUST 7, 2013. THEY COULD NOT IDENTIFY THE PROBLEM WITH THEIR SYSTEMS CHECK AND COULD NOT PRODUCE THE SAME ENGINE SHUT-OFF EVENT, WHILE OPERATING THE VEHICLE. *TR

WHEN ENTERING AN UP-RAMP TO A LIMITED ACCESS HIGHWAY AT SLOW SPEED, LESS THAN 30 MPH, AND TURNING TO THE RIGHT, THE ENGINE SUDDENLY DIED AND POWER WAS LOST TO STEERING AND BRAKES. WE WERE ABLE TO PULL OFF THE ROAD AND RESTART, BUT WERE JUST LUCKY THAT THIS DIDN'T HAPPEN ON A CURVE AT HIGH SPEED OR IN HEAVY TRAFFIC. TOOK THE CAR TO THE DEALER THE NEXT DAY, AND THEY WERE UNABLE TO REPEAT THE PROBLEM. *TR

I WAS A PASSENGER IN THE VEHICLE WHEN IT CRASHED INTO A FIRE HYDRANT DOING APPROXIMATELY 40MPH. THE SEATBELT FAILED TO LOCK AND THE AIRBAGS FAILED TO DEPLOY. THE CAR HAS MAJOR DAMAGE TO THE UNDERBODY, FRONT-END, THE INSIDE OF THE VEHICLE DASH, THE MOTOR MOUNTS, ENGINE AND OTHER DAMAGES ARE UNKNOWN AT THIS TIME. *TR

WHILE SLOWING DOWN, APPLYING BRAKES TO EXIT THE HIGHWAY INTO THE CLOVERLEAF OFF RAMP, STEERING BECAME VERY DIFFICULT AND I WAS FORCED TO CONTINUE IN THE CURRENT DIRECTION OFF THE ROAD INTO THE GRASS. UPON STOPPING NOTICED DASH LIGHTS WERE ON AND THE VEHICLE HAD STALLED. I WAS VERY LUCKY THAT I WAS HEADED INTO A GRASSY AREA AND NOT INTO A WALL AS I COULDN'T STEER IN ANY OTHER DIRECTION FROM WHEN I LOST POWER. HYUNDAI FOUND NO ERROR CODES AND COULDN'T REPLICATE THE PROBLEM.

I WAS ON A RETURN TRIP OF 5 HOURS OR SO EACH WAY WHICH I TOOK AT ABOUT 30,000 MILES ON THE ODOMETER, AND NOTICED A VERY PRONOUNCED DROP IN POWER AND ACCELERATION CAPABILITY QUITE SUDDENLY. IT WAS AS IF SOME WIRING OR HOSE HAD COME LOOSE UNDER THE HOOD. A FEW MONTHS LATER, WHEN THE PROBLEM HAD NOT CHANGED AT ALL IN OVER 3000 MILES OF DAY-TO-DAY DRIVING, INCLUDING A DAILY STINT (TO WORK) OF MAYBE 12 MILES EACH WAY ON THE FREEWAY WHICH ENTAILS ACCELERATING UP THE ON-RAMP INTO THE FLOW OF TRAFFIC, I STILL COULD FEEL THE DIFFERENCE IN ACCELERATION AND RESPONSE TIME WHILE ACCELERATING. WHEN I TOOK THE SANTA FE IN FOR A NORMAL OIL CHANGE, I REPORTED TO THE DEALER THESE SYMPTOMS, AND ASKED TO HAVE IT CHECKED OUT. THEY CHANGED THE OIL, AND CHECKED OUT THE COMPUTER READOUTS FOR THE VEHICLE, AND SAID THERE...

THIS INCIDENT OCCURRED AT NIGHT TIME. ABOUT 10 MIN FROM A COLD START, I TURNED ONTO THE 210 FWY. THERE WAS A 270 DEGREE DOWNHILL TURN (A STEEP CURVE) SO I HAD THE BRAKES ON WHILE DOING 15 MPH. HALF WAY INTO THE TURN, I SUDDENLY LOST BRAKE AND STEERING WHEEL FROZE. WITH SOME EFFORT, I MANAGED TO TURN THE STEERING AND STOP THE CAR. THE ENGINE DIED WITHOUT WARNING. LATER I SENT THE CAR TO DEALERSHIP BUT THEY COULD NOT REPRODUCE THE EVENT. *TR

TL* THE CONTACT OWNS A 2009 HYUNDAI SANTA FE. THE CONTACT STATED THAT THE VEHICLE STALLED NUMEROUS TIMES WITHOUT WARNING WHILE DRIVING AT VARIOUS SPEEDS. THE FAILURE RECURRED INTERMITTENTLY. THE VEHICLE WAS TAKEN TO THE DEALER SEVERAL TIMES FOR THE FAILURE WHERE A DIAGNOSTIC WAS PERFORMED TWICE BUT THE DEALER WAS UNABLE TO GENERATE A FAILURE CODE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 55,000 AND THE CURRENT MILEAGE WAS 57,004.
