2007 Kia Sorento Electronic Stability Control Esc Problems

IN FEBRUARY OF 2012 I TOOK MY 2007 KIA SORENTO INTO THE LOCAL KIA DEALERSHIP BECAUSE MY "ESC OFF" LIGHT KEPT COMING ON WHEN I WOULD MAKE A RIGHT HAND TURN. THE STEERING SOUNDED LIKE IT WAS GROANING AS I WAS IN THESE TURNS. WHEN THEY READ THE CODE IT CAME UP AS "P1739 ENCODE FAULT", WHICH ON MY PAPERWORK STATES CAN SIGNAL A COMMUNICATION ERROR. FURTHER INSPECTION SHOWED THAT THE TRANSFER CASE MOTOR WAS SEIZING UP AND CAUSING THE ISSUE. THE MOTOR WAS REPLACED AT THAT TIME. ON MARCH 11TH AS I WAS DRIVING ON THE HIGHWAY AT 75 MPH, THE LIGHT CAME ON AGAIN AND THE ENGINE SORT OF LOST POWER. I DROVE ON, TRIED TO TURN THE LIGHT OFF TO NO AVAIL. WHEN I WAS ABLE TO EXIT THE INTERSTATE, I SHUT OFF THE ENGINE AND WAITED A FEW MINUTES. I TURNED THE ENGINE BACK ON AND THE LIGHT WENT OFF. THIS HAPPENED AGAIN SIX DAYS LATER, ONCE AGAIN AT HIGHWAY SPEED. BOTH TIMES I HAD CRUISE CONTROL ON. BOTH TIMES THE ENGINE REACTED STRANGELY WHEN THE LIGHT CAME ON. AS BEFORE, WHEN THE CAR WAS TURNED OFF AND THEN BACK ON, THE LIGHT WENT OFF. I TOOK THE VEHICLE INTO THE DEALERSHIP AGAIN ON 3/21/13 AND ONCE AGAIN THE TRANSFER CASE MOTOR WAS THE ISSUE. THIS TIME IT HAD AN INTERNAL OPEN CIRCUIT. TRANSFER CASE MOTOR HAS BEEN REPLACED ONCE AGAIN. PART HAS A 12 MOS OR 12,000 MILE WARRANTY. FIRST INCIDENT HAPPENED AT 52,870 MILES AND SECOND INCIDENT AT 62,173 MILES. THIS PART FAILED AT LESS THAN 10,000 MILES, BUT OVER 12 MONTHS. FROM WHAT I HAVE READ, I AM ONE OF THE LUCKY ONES THAT HAS NOT ENDED UP IN A CRASH. DEFINITELY SCARY WHEN THIS HAPPENS AT 75-80 MPH. *TR

2007 KIA SORENTO...ESC LIGHT COMES ON, THEREBY DISABLING THE CRUISE CONTROL FUNCTION. CONSEQUENTLY, THE VEHICLE GOES INTO "LIMP" MODE, MEANING YOU DEPRESS THE ACCELERATOR AND YOU HAVE NO POWER. THIS HAS BEEN HAPPENING REPEATEDLY OVER THE LAST YEAR. IT HAS OCCUR AT LOW SPEEDS AND HIGHWAY SPEEDS. RECENTLY, IT OCCURRED WHILE MAKING A LEFT TURN, EXPOSING THE VEHICLE INTO ONCOMING TRAFFIC. LUCKILY, THE OTHER VEHICLES WERE ABLE TO SLOW DOWN AND STOP. EVERY TIME IT HAPPENS, WE HAVE TO STOP THE VEHICLE, PUT IN PARK AND TURN IT OFF. EVEN THEN, IT WILL HAPPEN MULTIPLE TIMES DURING THE SAME TRIP. *TR

I AM AN OWNER OF A 07 KIA SORENTO EX. A FEW MONTHS AGO I NOTICED THE "ESC OFF" LIGHT WOULD ILLUMINATE AT RANDOM INSTANCES AND WOULD NOT TURN OFF UNTIL THE VEHICLE'S ENGINE WAS TURNED OFF AND THEN RESTARTED AGAIN. THIS ISSUE IS OF CONCERN TO MYSELF AS WELL AS OTHER KIA OWNERS I HAVE COME ACROSS. REASON BEING, WHEN THE "ESC OFF" LIGHT ENGAGES AND STAYS ON, THE VEHICLE LOSES POWER WHILE DRIVING. I HAVE HAD TWO SEPARATE OCCASIONS WHERE THIS HAS HAPPENED ON THE FREEWAY. WHILE CHANGING LANES AND TRYING TO ACCELERATE, I WAS STUCK AT A SPEED OF 50MPH WITH TRAFFIC BEHIND ME AT 65MPH OR FASTER. ASSUMING THAT I WAS GOING TO ACCELERATE THE VEHICLES BEHIND ME HAD TO SLAM ON THEIR BRAKES INSTEAD. WHEN I TOOK MY KIA TO THE DEALER TO DIAGNOSE THE PROBLEM I WAS INFORMED THAT I AM NOT THE FIRST CUSTOMER EXPERIENCING THIS PROBLEM AND THAT THERE IS A SERVICE BULLETIN POSTED REGARDING THE "ESC OFF" LIGHT ILLUMINATING AND VEHICLE THROTTLE LOSS. THE DIAGNOSTIC CHECK READ, THAT THERE IS A TRANSFER CASE DECODER MOTOR FAULT. I WAS TOLD KIA WAS OFFERING TO COVER THE REPAIRS UNDER 60000MI WARRANTY BUT THAT I CAME IN AT 62000 AND DID NOT COMPLY WITH RECOMMENDED TRANSFER CASE SERVICES LISTED IN THE MANUAL, THEY WOULD NOT COVER UNDER ANY WARRANTY. KIA BELIEVES THAT MY LACK OF TRANSFER CASE SERVICE TO MY VEHICLE IS THE REASON FOR THIS PROBLEM. I CAN'T HELP BUT TO THINK, THAT BASED ON HOW MANY KIA SORENTO CONSUMERS ARE HAVING THIS SAME PROBLEM THERE MAY BE A DEFECT IN KIA'S "ESC" SYSTEM. IN MY EXPERIENCE WITH THIS ISSUE I CAN SAY THAT I BELIEVE THIS TO BE A SERIOUS SAFETY HAZARD WHILE DRIVING. *TR
