2005 Hyundai XG350

DT*: THE CONTACT STATED THE VEHICLE STALLED UPON ACCELERATION FOR THE FIRST 5-10 MINUTES THE VEHICLE WAS DRIVEN. AFTER PUMPING THE ACCELERATOR PEDAL A FEW TIMES, THE VEHICLE WOULD START. THE DEALERSHIP WAS AWARE OF THE PROBLEM AND DETERMINED THIS WAS A CHARACTERISTIC OF THE VEHICLE. UPDATED 10/4/2006 - THE CONSUMER INDICATED THAT EACH MORNING THE VEHICLE WAS STARTED, PUT INTO DRIVE AND DRIVEN INTO TRAFFIC IT STUMBLED AND WOULD NOT ACCELERATE. WHEN THE CONSUMER LETS OFF THE ACCELERATOR PEDAL THE VEHICLE ACCELERATED SUDDENLY. *NM

DT*: THE CONTACT STATED THE VEHICLE ACCELERATES WITHOUT THE ACCELERATOR PEDAL BEING DEPRESSED. THIS HAS OCCURRED ON FOUR OCCASIONS, ONCE CAUSING AN ACCIDENT. THE RPMS SHOOT UP TO THE TOP. THE VEHICLE HAS BEEN TAKEN TO THE DEALER HOWEVER THEY HAVE NOT BE ABLE TO DUPLICATE THE PROBLEM. 08/29/06 CERTIFIED LETTER RECEIVED BY HYUNDAI ON 7/30/06. NO RESPONSE BY HYUNDAI OR BY PRICE. *TT

DT*: THE CONTACT STATED THAT THE VEHICLE WAS HAVING PROBLEMS WITH THE ACCELERATOR CAUSING THE RPM TO RUN HIGH AND THE VEHICLE TO OVER-ACCELERATE. DURING ONE INCIDENT WHILE PULLING THE VEHICLE OUT OF A PARKING SPACE AND BARELY TAPPING ON THE GAS PEDAL IN REVERSE, THE VEHICLE OVER ACCELERATED ALMOST HITTING A PEDISTRIAN. THE VEHICLE WAS TAKEN TO THE DEALERS ON FOUR SEPERATE OCCASIONS AND THEY COULD NOT DETERMINE THE SOURCE OF THE PROBLEM. THE DEALER WILL NO LONGER PROVIDE FURTHER ASSISSTANCE.*AK

SEVEN INSTANCES OF UNWANTED ENGINE ACCELERATION SINCE JAN 2006. ALL OCCURRENCES SIMILAR: 1)ENGINE IS WARM AFTER A PERIOD OF DRIVING; 2) CAR DECELERATING APPROACHING STOP SIGN, TRAFFIC LIGHT, OR IN STOP-AND-GO TRAFFIC; 3) A BARELY AUDIBLE "CLICK" IS HEARD AND THE ENGINE RPM BEGINS TO REV UP MAKING BRAKING DIFFICULT AND GIVING A CLUE THAT SOMETHING IS AMISS. WHEN THIS POINT IS REACHED KEY WAS TURNED OFF OR IDLE SELECTED TO SEE HOW HIGH THE RPM WOULD REV; 4800 IS THE HIGHEST NOTED. THIS IS A RANDOM EVENT AS THE CAR HAS OVER 10000 MILES WITH 7 OCCURRENCES. LATEST DATE IS NOTED BELOW. *JB

MY 2005 HYUNDAI XG350 HAS A VERY DANGEROUS HESITATION PROBLEM. THIS PROBLEM IS GENERALLY ENCOUNTERED FORM A COLD START OUT OF A PARKING LOT OR GARAGE. THE GAS PEDAL IS SLOWLY DEPRESSED TO ACCELERATE. SOMETIMES, IT RESPONDS NORMALLY. AT OTHER TIMES IT JUST COASTS NO MATTER HOW HARD YOU PUSH ON GAS PEDAL. SUDDENLY IT WILL LURCH FORWARD WITH ENORMOUS TORQUE (DEPENDING ON HOW THE DRIVER RESPONDS TO THE COASTING PROBLEM). THERE ARE TWO PROBLEMS WITH THIS HESITATION: 1) PULLING INTO TRAFFIC AND THAN NOT ACCELERATING CAN CAUSE ACCIDENTS 2) MORE IMPORTANTLY, THE UNEXPECTED QUICK ACCELERATION CAN CAUSE LOSS OF CONTROL, HITTING SOMETHING OR SOMEBODY, OR WORSE. RESOLUTION TO THIS PROBLEM IS NOT CONSIDERED BY HUYNDAI AT THIS POINT. DENIAL OF OTHER CARS HAVING SIMILAR PROBLEMS ARE COMMON AT FACTORY LEVEL, BUT ARE ADMITTED AT DEALERSHIP LEVEL. INCIDENT DATE IS FIRST TIME. *NM
