2009 Kia Sedona Engine Problems

Your engine isn't responding properly when you try to accelerate from a stop — instead, it just idles and keeps RPMs at around 500. The dealer diagnosed this as a faulty computer chip that controls engine performance. Replacing the engine control module (computer chip) should resolve the acceleration issue.

CONSTANT POOL OF OIL UNDER THE HOOD. (TO ME IT IS IN THE ENGINE COMPARTMENT - I'VE BEEN TOLD IT'S NEAR THE TRANSMISSION CASE AND ALSO TOLD IT'S NEAR THE INTAKE MANIFOLD). THE OIL POOL WAS FIRST NOTICED BY MY HUSBAND WHEN HE WAS CHECKING OUR FLUIDS BEFORE A TRIP. IT WAS POINTED OUT TO THE DEALER IN JULY WHEN WE WERE THERE WITH ENGINE PROBLEMS AND THEY "CLEANED OIL OFF" AS STATED ON INVOICE. WHEN QUESTIONED ABOUT IT THEY HAD NO ANSWER AS TO WHAT IT WAS FROM. THE OIL WAS THERE AGAIN AND HAS BEEN THERE CONSTANTLY SINCE JULY. THE DEALER TELLS US IT'S OIL THAT'S BEEN SPILLED FROM OIL CHANGES BUT EVERYTIME THEY CLEAN IT OFF IT APPEARS AGAIN. THE OIL WAS CLEANED OFF TWICE IN OCTOBER BUT IT'S STILL THERE. ENGINE IS ALSO VERY LOUD AND VIBRATES. MANUFACTURER WAS NOTIFIED IN JULY - NO WORK PERFORMED OTHER THAN WIPING IT OFF AND NO DIAGNOSTICS TO FIGURE OUT WHERE IT'S COMING FROM. *TR
