2005 HYUNDAI ELANTRA Engine And Engine Cooling Problems

ON DECEMBER 10, 2011, I WAS TURNING FROM NORTHBOUND GARY AV. ONTO EASTBOUND LAWRENCE AVE. AT APPROXIMATELY 5 MPH. WHILE I WAS TURNING MY ACCELERATOR STUCK THE ENGINE SPED OUT OF CONTROL TO AT LEAST 40 MPH. I SWERVED TO AVOID HITTING A TRUCK TURNING ONTO GARY AND MY CAR WENT OVER THE SOUTH CURB.. AND MY ATTEMPTS TO BREAK WERE FAILING ALL THIS TIME... I CRASHED THROUGH A FENCE INTO SOMEBODY'S BACK YARD WENT DOWN HILL ABOUT 50 FEET AND RAN INTO A TREE. I THEN TURNED OFF THE IGNITION. THE AIRBAG DID NOT DEPLOY. THE INVESTIGATING BLOOMINGDALE POLICE OFFICER STARTED THE CAR AND THE ACCELERATOR WAS STILL STUCK IN THE WIDE OPEN POSITION. THE BODY SHOP PERSONNEL ALSO CONFIRMED THE ACCELERATOR WAS STUCK. *TR

ON 10/24/09 I WAS DRIVING MY CAR FOR APPROXIMATELY AN HOUR AND A HALF WHEN I NOTICED A SLIGHT JERKING FEELING. IT REPEATED ONCE OR TWICE. LATER WHEN DRIVING HOME, AFTER DRIVING FOR ABOUT A HALF AN HOUR IT STARTED UP AGAIN. THEN ABOUT AN HOUR LATER IT STALLED AT A RED LIGHT, I HARDLY MADE IT HOME. I TOOK IT TO THE MECHANIC AND IT WASN'T DISPLAYING THE PROBLEM. IT STARTED UP THE NEXT DAY AND THE CHECK ENGINE LIGHT CAME ON. IT PULLED A PO 420 CODE. I CHANGE THE O2 SENSOR, DIDN'T FIX IT CHECK ENGINE LIGHT BACK ON SAME CODE. I CHANGED MY MID CAT CONVERTER DIDN'T FIX IT, LIGHT BACK ON SAME CODE...MY MECHANIC THINKS WE SHOULD CHANGE UPPER CAT CONVERTER, I CALL THE DEALER. THEY SAY THE UPPER CAT IS CONNECTED TO THE MANIFOLD WHICH MEANS I'M STILL COVER UNDER THE 100K WARRANTY. MIND...

I HAVE A 5-SPEED GT HATCHBACK THAT STALLED WHILE STOPPED AT A STOP SIGN IN JULY OF 2005. THE CAR WOULD RUN ERRATICALLY AND TRY TO STALL WHILE MOVING. IT SEEMED TO DO IT WHEN THE COOLING FAN CAME ON. TOOK TO DEALER 8/1/05. THEY COULD NOT DUPLICATE THE PROBLEM. THEY DID REPLACE THE THROTTLE POSITION SENSOR. I HAD 417 MILES ON IT AT THAT TIME. I HAD NO PROBLEMS UNTIL 3/30/06. THE FIRST WARM DAY IN PA AND THE CAR STARTED STALLING AGAIN, AND LEAKING FUEL IN THE LEFT REAR WHEEL WELL. WITH ONLY 6900 MILES. I HAVE A SERVICE APPOINTMENT 4/3/06. LET'S HOPE I CAN GET THIS FIXED THIS TIME BEFORE SOMETHING BAD HAPPENS. IT SEEMS TO ONLY STALL WHEN WARMED UP AND THE OUTSIDE TEMP IS ABOVE 65 DEGREES. *JB
