2005 Hyundai XG350

VEHICLE SPEED CONTROL IS ERRATIC AND CANNOT BE PREDICTED ON OCCASION. SOMETIMES THE VEHICLE WILL JUMP QUICKLY AT THE SMALLEST TOUCH OF THE ACCELERATOR AND OTHER TIMES IT WILL NOT MOVE FASTER THAN ABOUT 5 MPH NO MATTER HOW MUCH THE THROTTLE IS PRESSED. THIS CAUSES SERIOUS SAFETY ISSUES AS ENTERING A ROADWAY CAN BE DANGEROUS WITH LITTLE TO NO POWER AVAILABLE AT TIMES. IT ALSO MAKES NAVIGATING A SMALL AREA SUCH AS A PARKING LOT UNSAFE WHEN THE POWER IS DELIVERED FAR TOO QUICKLY. INCIDENTS TYPICALLY HAPPEN 3-4 TIMES PER DAY (MY TYPICAL COMMUTE IS ABOUT 60 MILES PER DAY). THE INCIDENTS USUALLY NEVER LAST MORE THAN 20 OR 30 SECONDS. *TR

TL*THE CONTACT OWNS A 2005 HYUNDAI XG350. WHILE DRIVING 5 MPH, THE CONTACT ATTEMPTED TO STOP THE VEHICLE, BUT IT CONTINUED TO ACCELERATE. SHE HAD TO EXERT MAXIMUM PRESSURE TO THE BRAKE PEDAL IN ORDER TO STOP THE VEHICLE. THE VEHICLE WAS TAKEN TO A LOCAL REPAIR SHOP, BUT THE MECHANIC WAS UNABLE TO LOCATE THE CAUSE OF THE FAILURE. THE CONTACT IS IN THE PROCESS OF NOTIFYING THE MANUFACTURER. THE FAILURE MILEAGE WAS 40,000 AND THE CURRENT MILEAGE WAS 41,000. UPDATED 10/06/09 *BF THE CONSUMER STATED ON A SEPARATE OCCASION WHEN THE CRUISE CONTROL WAS SET, THE VEHICLE INCREASE IN SPEED UP TO 80 MPH. UPDATED 10/08/09

TL*THE CONTACT OWNS A 2005 HYUNDAI XG350. THE CONTACT STATED THAT THE RPMS WOULD INCREASE UNEXPECTEDLY. HE NOTICED THE FAILURE ON THREE OCCASIONS. EVEN WHEN PRESSING FIRMLY ON THE BRAKE PEDAL, THE VEHICLE WOULD CONTINUE TO ACCELERATE. HE SHIFTED INTO NEUTRAL IN AN ATTEMPT TO GAIN CONTROL OF THE VEHICLE, BUT IT CONTINUED TO REV UP UNTIL HE TURNED THE IGNITION KEY TO SHUT IT OFF. THE FAILURE SOMETIMES OCCURRED WHEN HE ATTEMPTED TO DECELERATE. HE TOOK THE VEHICLE TO TWO DIFFERENT DEALERS, BUT THEY COULD NOT DUPLICATE THE FAILURE OR PROVIDE A FAILURE CODE. THE MANUFACTURER WAS NOT NOTIFIED. THE CURRENT MILEAGE WAS APPROXIMATELY 43,000 AND FAILURE MILEAGE WAS APPROXIMATELY 40,000.

2005 XG350 HAS HAD TWO SPECIFIC PROBLEMS RELATED TO ENGAGING CAR IN DRIVE AND ACCELERATION. WHEN CAR HAS BEEN SITTING OVERNIGHT OR FOR A PROLONGED PERIOD OF TIME AND IT IS PLACED IN DRIVE, THE CAR JUST SITS THERE IN EXCESS OF 15 SECONDS AND THEN TRANSMISSION CLUNKS INTO GEAR AND STARTS GOING. THIS PROBLEM OCCURS DAILY WHEN CAR IS FIRST STARTED AND REAPPEARS IF CAR COOLS DOWN FOR SEVERAL HOURS AFTER IT HAS BEEN DRIVEN. RELATED TO THIS PROBLEM IS ACCELERATION OF VEHICLE. AFTER GEAR FINALLY ENGAGES, THE SLIGHTEST PRESSURE ON THE GAS PEDAL CAN SEND THE CAR LURCHING FORWARD QUICKLY. THE OTHER DAY WHILE BACKING OUT OF THE DRIVEWAY AND THEN PLACING CAR IN DRIVE, WAS ALMOST HIT BY ANOTHER CAR COMING DOWN THE STREET THAT NO DOUBT EXPECTED US TO BE MOVING. EVEN THOUGH WE HAD PLACED THE CAR IN DRIVE, IT WENT NOWHERE. LUCKY THE OTHER GUYS STOPPED IN TIME OR WE WOULD HAVE BEEN HIT. THIS COULD BE A REAL SAFETY ISSUE. WE HAVE REPORTED THESE PROBLEMS TO DEALER ON TWO SEPARATE OCCASIONS BUT THEY HAVE BEEN UNABLE TO REPLICATE THEM AND NOTHING HAS BEEN DONE TO RESOLVE OUR PROBLEM. *TR

PURCHASED XG350 IN DECEMBER 2005 ON TWO OCCASIONS WHEN FIRST LEAVING THE DRIVEWAY NOTICED THAT WHEN PRESSING THE ACCELERATOR THE CAR DID NOT RESPOND. AFTER RELEASING AND TRYING A COUPLE MORE TIMES THE CAR THEN LURCHED FORWARD. THAT WAS SHORTLY AFTER THE PURCHASE. NOW HAVE A LITTLE OVER 26,000 MILES ON SEVERAL OCCASIONS WHEN PRESSING THE ACCELERATOR THE CAR SEEMED TO SURGE FORWARD FOR THE AMOUNT OF PRESSURE. ON JULY 16, 2007 LEFT THE DRIVEWAY AND THE CAR WOULD NOT RESPOND TO PRESSURE. KEPT TRYING FOR ABOUT 1/2 MILE PRESSING AND RELEASING AND JUST AS I WAS GOING TO TURN AROUND THE CAR SURGED FORWARD AND DROVE FINE FOR THE LAST TWO DAYS. I WILL BE TAKING IT TO A HYUNDAI REPAIR SERVICE DEPARTMENT SOON AS THIS COULD BE VERY DANGEROUS IF PULLING INTO OR DRIVING IN HEAVE TRAFFIC. *AK

ON TWO SEPARATE OCCURANCES MY 05 HYUNDAI XG350, WHEN IN CITY TRAFFIC AT APPROX 35MPH, FAILED TO DROP ENGINE RPM WHEN THE BRAKES WERE APPLIED DURING A TRAFFIC LIGHT STOP. TO STOP THE CAR, I HAD TO SHIFT THE CAR TO NEUTRAL. THE ENGINE RACED THEN IMMEDIATELY DROPED TO AN IDLE. THIS EASILY COULD HAVE RESULTED IN AN INCIDENT HAD I NOT SHIFTED TO NEUTRAL. LOCAL DEALER ADVISED THAT ALL WAS OK - NO PROBLEMS!

SPEED CONTROL - ACCELERATION. ON 10 OCCASIONS SINCE 03/05 THE ACCELERATOR PEDAL CAN BE DEPRESSED, NOTHING HAPPENS, AND THEN THE VEHICLE TAKES OFF. YESTERDAY WAS THE LAST STRAW - BACKING UP AND IT DID IT. WHEN IT DID TAKE OFF WITH ACCELERATOR DEPRESSED ABOUT HALF WAY, IT TOOK OFF AND EVEN THOUGH I WAS READY FOR IT TO DO THAT I COULDN'T GET IT STOPPED QUICK ENOUGH AND IT HIT A POLE. IT TORE REAR BUMPER. I HAVE HAD IT TO DEALER 4 TIMES AND THEY KEPT CAR FOR 5 DAYS AND COULD NOT DUPLICATE THE PROBLEM. TOLD US UNTIL THEY CAN GET IT TO DO IT WHILE THEY HAD IT - THERE ISN'T ANYTHING THEY CAN DO. SO FAR WHEN IT HAS HAPPENED PULLING OUT INTO TRAFFIC WE WERE ABLE TO AVOID GETTING HIT. CANNOT UNDERSTAND WHY NHTSA HASN'T ADDRESSED THIS PROBLEM. PERHAPS BECAUSE NO DOCUMENTED DEATHS HAVE OCCURRED.....*JB

CAR ACCELERATES/LURCHES FORWARD WHEN IDLE OR STARTING TO DRIVE FROM A STANDSTILL. THIS HAPPENS INTERMITTENTLY AND MY WIFE HAS TAKEN IT TO THE DEALER TWICE FOR THIS. THE DEALER STATES THEY CANNOT FIND ANYTHING WRONG. WELL, BY READING THE COMPLAINTS ON THIS SITE ABOUT THE SAME PROBLEM MY WIFE IS EXPERIENCING, THERE IS A PROBLEM, AND A SERIOUS ONE. *JB

TL* - THE CONTACT OWNS A 2005 HYUNDAI XG 350. WHEN ACCELERATING THE VEHICLE WOULD NOT RESPOND; THE CONTACT COULD FEEL THE GEARS SHIFT AND THE VEHICLE MOVING SLOWLY. THE DEALER STATED THEY WERE UNABLE TO DIAGNOSE THE FAILURE. THE CONTACT CALLED THE MANUFACTURER AND WAS UNABLE TO GET A RESPONSE. *AK UPDATED 03/19/07. *JB
