2006 Hyundai Santa Fe Speed Control & Cruise Problems

The contact owns a 2006 Hyundai Santa Fe. The contact stated while driving approximately 70 mph when the vehicle began to accelerate without the accelerator pedal being depressed. The contact was able to pull over and noticed smoke coming from the engine compartment. The contact stated no warning lights were illuminated. The vehicle was towed to a local mechanic where it was not diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 143,000.

ON MARCH 4, 2020, HEADING HOME AT NIGHT ON A CURVY MOUNTAIN ROAD MY CAR (2006 HYUNDAI SANTA FE) SUDDENLY JERKED, STARTED TO ACCELERATE TO OVER 80 MILES HOUR. AT THE SAME TIME HALF OF THE PANEL LIGHT BEHIND PART OF THE RPM'S AND HALF BEHIND THE MPH WENT OUT; THE REST OF THE PANEL WAS STILL LIT UP; I WAS HEADING DOWN THE CURVY ROAD ACCELERATING HEADING QUICKLY TOWARDS AN 18 WHEELER WHEN I TRIED TO BRAKE, MY BRAKE PEDAL WOULD NOT MOVE AND MY CAR KEPT ACCELERATING (I WAS NOT STEPPING ON THE GAS PEDAL). I QUICKLY DROPPED MY CAR INTO LOW GEAR AND MANEUVERED AROUND THE 18-WHEELER AND TRYING THE BRAKES, THE EMERGENCY BRAKES, AND AS QUICKLY AS IT STARTED UP, IT STOPPED, AND MY CAR STARTED TO DRIVE NORMAL (EXCEPT THE PANEL LIGHTS). ON MY WAY HOME (MARCH 5TH), IT HAPPENED AGAIN WHILE DRIVING DOWN THE CURVY MOUNTAIN ROAD AT NIGHT! AS I BEGIN DESCENDING THE CURVY ROAD (DRIVING 40MPH IN THE RIGHT LANE), MY CAR SUDDENLY BEGAN ACCELERATING AGAIN UP TO 90MPH! THERE WERE NOT AS MANY PEOPLE ON THE ROAD, SO I WAS ABLE TO MANEUVER IT BY DROPPING DOWN INTO LOW GEAR AND AS I BEGAN ASCENDING THE MOUNTAIN ROAD, THE UNINTENDED ACCELERATION STOPPED, AND THE CAR DROVE NORMAL. EACH INCIDENT LASTED ABOUT 5 MINUTES. ON MARCH 6, 2020, I TOOK MY CAR TO THE MECHANIC AND RAN A DIAGNOSTIC AND DID NOT FIND A CAUSE. HE TOLD ME TO CALL THE HYUNDAI DEALERSHIP TO SEE IF THERE WERE ANY RECALLS. THE DEALERSHIP INFORMED ME TO CONTACT HYUNDAI HEADQUARTERS, WHICH I DID. I REPORTED MY ISSUE AND MADE A CLAIM ON MARCH 6, 2020. I WAS TOLD TO TAKE MY CAR TO CAPITAL HYUNDAI DEALERSHIP AND HYUNDAI HEADQUARTERS WOULD SEND A FORENSIC ENGINEER OUT TO INVESTIGATE THE ISSUE. THEY TOLD ME TO NOT DRIVE MY CAR AND HAVE IT TOWED. I RECEIVED A CALL FROM HYUNDAI HEADQUARTERS INFORMING ME THE DEALERSHIP RAN A DIAGNOSTIC ON MY CAR AND DID NOT FIND ANYTHING WRONG AND COULD NOT DUPLICATE THE UNINTENDED ACCELERATION.

TL* THE CONTACT OWNS A 2006 HYUNDAI SANTA FE. WHEN THE CONTACT SHIFTED THE GEAR IN REVERSE, THE VEHICLE ACCELERATED BACKWARDS ON ITS OWN. AS A RESULT, THE VEHICLE CRASHED INTO A BRICK WALL. THE DRIVER THEN SHIFTED INTO THE DRIVE POSITION AND THE FAILURE RECURRED. AS A RESULT, THE VEHICLE DROVE FORWARD THROUGH THE NEIGHBOR'S FENCE BEFORE CRASHING INTO A PARKED VEHICLE. THERE WERE NO INJURIES AND A POLICE REPORT WAS FILED. THE DRIVER STATED THAT THE BRAKES WERE INOPERABLE DURING THE FAILURES. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE DEALER AND MANUFACTURER WERE NOT NOTIFIED OF THE FAILURES. THE FAILURE MILEAGE WAS 155,000. *JS

FOUR SEPARATE INCIDENTS WITHIN A 30 DAY PERIOD AT HIGHER SPEEDS (>65 MPH ON A FREEWAY) OF UNINTENDED ACCELERATION, REMEDIATED BY SHIFTING INTO NEUTRAL AND BRAKING HARD WITHOUT PUMPING. THESE ACTIONS DISENGAGED THE ACCELERATION WITHOUT HAVING TO COME TO A COMPLETE STOP AND TURNING THE IGNITION OFF. UNINTENDED ACCELERATION OCCURRED AGAIN, IN THE LATEST INCIDENT WHILE TRAVELING AT 40 MPH ON A CITY STREET, HOWEVER CAR WOULD NOT COME TO A COMPLETE STOP EVEN WITH FULL WEIGHT ON THE BRAKE, AND WHILE SHIFTING INTO NEUTRAL SOLVED THE IMMEDIATE ACCELERATION PROBLEM, THE IGNITION HAD TO BE TURNED OFF TO BRING THE VEHICLE TO A FULL STOP. DRIVER ALMOST WRECKED SEVERAL CARS WHILE TRYING TO DODGE TRAFFIC AS CAR ACCELERATED VERY RAPIDLY. THIS COULD HAVE BEEN HAD A TRAGIC ENDING BUT FORTUNATELY ONLY RESULTED IN A MECHANICS' VISIT.

TL* THE CONTACT OWNS A 2006 HYUNDAI SANTA FE. WHILE DRIVING APPROXIMATELY 5 MPH, THE VEHICLE SUDDENLY ACCELERATED INDEPENDENTLY WITHOUT WARNING. THE VEHICLE WAS TAKEN TO A DEALER, BUT THE FAILURE WAS UNABLE TO BE DIAGNOSED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 59,000. UPDATED 1/15/16 *CN THE CONSUMER STATED THE DEALER PERFORMED TWO ECM UPDATES. UPDATED 01/25/16.*JB

STOPPED AT AN INTERSECTION, FOOT ON BRAKE, ENGINE BEGAN REVVING, THEN DECELERATED, BUT REVVED AGAIN, THIS TIME FORCING MY CAR FORWARD. ANOTHER VEHICLE WAS APPROACHING FROM THE LEFT, SO I STEERED RIGHT. IMPACT ON LEFT FRONT WHEEL, CAR CAREENED INTO A LIGHTWEIGHT PLASTIC TYPE FENCE AND STOPPED. MY FOOT REMAINED ON THE BRAKE THE ENTIRE TIME. I WAS WEARING MY SEAT BELT AND WAS NOT INJURED. THE OTHER DRIVER WAS TRANSPORTED TO THE HOSPITAL BY AMBULANCE. BOTH VEHICLES WERE INSPECTED BY THE SAME INSURANCE ADJUSTER AND TOTALED. I HAVE FILED A COMPLAINT WITH HYUNDAI, BUT SO FAR, THEY HAVE NOT SENT AN INVESTIGATOR TO CHECK OUT THE VEHICLE. *TR

TL*THE CONTACT OWNS A 2006 HYUNDAI SANTA FE. THE CONTACT STATED THAT THE VEHICLE ACCELERATED WHILE THE CONTACT HAD HIS FOOT ON THE BRAKE PEDAL.

THE MANUFACTURER WAS NOT CONTACTED. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 53,900 AND CURRENT MILEAGE WAS 54,000.

I HAVE A 2006 SANTA FE 6 CYL. FRONT WHEEL DRIVE. I PURCHASED THE CAR IN 2007 FROM GO HYUNDAI. THE CAR HAS RUN VERY GOOD, EXCEPT THE SURGING OR ACCELERATION PROBLEM. I TOOK IT BACK TO THE DEALER TWO TIMES SPECIFICALLY FOR THIS PROBLEM. THEY SAID THEY COULD FIND NO PROBLEM. I TOOK IT TO A SECOND DEALER, PLANET HYUNDAI, AND THEY COULD FIND NOTHING. THE PROBLEM GOT SO BAD EVEN I WAS AFRAID TO DRIVE IT. MY WIFE WAS REALLY SCARED TO DRIVE IT. I FINALLY TOOK IT BACK GO AND THEY CALLED, SAID IT WAS READY. WHEN I PICKED IT UP, THE SERVICE GUY SAID THEY REPLACED A PART AND THAT I SHOULDN'T HAVE ANY MORE SURGING PROBLEMS. LAST NIGHT, MY WIFE DROVE THE SANTA FE TO CHURCH. AS SHE WAS PARKING IT IN THE GARAGE, (SOMETHING SHE HAD DONE A THOUSAND TIMES), THE CAR SUDDENLY ACCELERATED, SLAMMING INTO OUR VOLVO CONVERTIBLE, PUSHING IT ABOUT FIVE FEET FORWARD, JAMMING IT UNDER OUR STAIRS INTO THE HOUSE. IN ALL, THERE IS A LOT OF DAMAGE TO BOTH VEHICLES. *TR

OCCASIONALLY, WHEN ACCELERATING FROM A STOP POSITION THE CAR WILL UNEXPECTEDLY SURGE FORWARD. WE HAVE HAD THIS CAR FOR 3 YEARS NOW AND IT HAS HAPPENED ABOUT 6 TIMES SO FAR. CONSEQUENCES HAVE BEEN NONE SO FAR, BUT I AM CONCERNED SOMETHING MAY HAPPEN IN THE FUTURE. *TR

I HAVE COMPLAINED TO MFG. OF THE PROBLEM I HAVE WITH ACCELERATION. WHEN GAS PEDAL IS PRESSED FROM A STOPPED POSITION THE SUV POWER SURGES, THERE IS NO SMOOTH ACCELERATION. NO MATTER HOW YOU TRY TO CONTROL THE PRESSURE ON THE PEDAL, THE VEHICLE JUST TAKES OFF. I HAD THIS CHECKED OUT 2X SINCE BUYING VEHICLE IN DEC. O7. AND HAVE BEEN TOLD THAT IS THE WAY THE COMPUTER WORKS WITH THE VEHICLE. I FIND THIS TO BE VERY UN-NERVING AND DANGEROUS. THIS IS A CONTINUOUS PROBLEM, AND I HAVE HAD A FRIEND DRIVE VEHICLE AND HE HAS THE SAME PROBLEM. *TR

MY 2006 HYUNDAI SANTA FE HAS EXPERIENCED FROM THE TIME OF PURCHASE A LONG LAG TIME BETWEEN DEPRESSING THE ACCELERATOR AND THE VEHICLE STARTING TO MOVE. THE TIME CAN BE UP TO A FEW SECONDS. THIS HAS BEEN ANNOYING AND AT TIMES DANGEROUS. IF THE VEHICLE ALWAYS DID THIS, YOU COULD GET USED TO IT, THOUGH IT IS STILL NOT SAFE. UNFORTUNATELY, THERE ARE TIMES WHEN BARELY DEPRESSING THE ACCELERATOR RESULTS IN INSTANT TIRE SPINNING AND ASSOCIATED QUICK ACCELERATION. THE INCONSISTENT NATURE OF THE ACCELERATOR RESPONSE MAKES THE VEHICLE DANGEROUS. AS MY DAUGHTER IS LEARNING TO DRIVE, I CANNOT LET HER USE THE VEHICLE BECAUSE WITH ANY INEXPERIENCED DRIVER, THIS CAR WOULD BE DEADLY. I HAVE BROUGHT THE CAR TO THE DEALER ONCE (IN PA) AND WAS BRUSHED OFF WITH THE EXCUSE THAT THE ENGINE COMPUTER DID NOT REPORT ANY PROBLEM. *TR

TL*THE CONTACT OWNS A 2006 HYUNDAI SANTA FE. THE CONTACT STATED THAT WHENEVER THE ACCELERATOR PEDAL WAS DEPRESSED FROM A STOPPED POSITION, THE VEHICLE WOULD LUNGE FORWARD. ALSO, THE VEHICLE WOULD ACCELERATE UP TO 15 MPH ALTHOUGH THE ACCELERATOR PEDAL HAD NOT BEEN DEPRESSED. THE DEALER STATED THAT THE LINK SYSTEM COULD BE THE CAUSE OF THE FAILURE. THE MANUFACTURER SENT OUT A TECHNICIAN TO INSPECT THE VEHICLE BUT COULD NOT DUPLICATE THE FAILURE. THE VIN WAS UNAVAILABLE. THE FAILURE MILEAGE WAS 15 AND THE CURRENT MILEAGE WAS APPROXIMATELY 11,000.
