NHTSA Complaint #10490074 — 2011 HYUNDAI SANTA FE

WHILE TRAVELING APPROX 55 MPH, I HIT A FAIRLY SIGNIFICANT POTHOLE. THE CHECK ENGINE LIGHT IMMEDIATELY CAME ON AND, AT THE VERY SAME INSTANT, THE GAS PEDAL CEASED TO FUNCTION. THE ENGINE REMAINED RUNNING, HOWEVER THE GAS PEDAL HAD NO AFFECT - E.G. PRESSING THE GAS PEDAL DID NOTHING. I IMMEDIATELY PULLED ONTO THE SHOULDER AND BROUGHT THE VEHICLE TO A COMPLETE STOP. THE ENGINE CONTINUED TO IDLE AND, AFTER LETTING UP ON THE BRAKE, THE VEHICLE MOVED FORWARD ON ITS OWN AT APPROX 20 MPH, MORE THAN EXPECTED UNDER NORMAL IDLE CONDITIONS. THIS CONDITION LASTED FOR APPROX 5 MIN UNTIL I COULD PULL INTO A PARKING LOT. I SHUT THE ENGINE OFF, WAITED A MOMENT, THEN RESTARTED IT. AT THIS POINT THE GAS PEDAL WAS FUNCTIONING AS EXPECTED, BUT THE CHECK ENGINE LIGHT REMAINED ON. THE VEHICLE WAS REPAIRED AT THE DEALER WHO NOTIFIED ME OF AN EXISTING TECHNICAL SERVICE BULLETIN, #12-FL-004, FROM HYUNDAI. THEY ALSO INDICATED THIS WAS A "KNOWN ISSUE" RELATING TO THE "ECM SOFTWARE." *TR
