NHTSA Complaint #10122340 — 2004 FORD F-350

INCIDENT OCCURRED IN THE AFTERNOON, THE TEMP WAS ABOUT 70 DEGREES. THE TRUCK WAS LOADED WITH MY FAMILY (5 INCLUDING MYSELF); WE WERE TRAVELING OVER A HILL AT ABOUT 50 MPH. A SIGN INDICATED A 6 PERCENT GRADE. ON THE WAY UP THE HILL, AT ABOUT 2000RPM AND ABOUT 45 MPH WE NOTICED A LARGE AMOUNT OF BLACK SMOKE BEING EXPELLED FROM THE TAILPIPE. THERE WAS NO HESITATION ON POWER OUTPUT AT THAT TIME, THEN COASTING DOWN THE OTHER SIDE OF THE HILL THE ENGINE SHUT DOWN. FORTUNATELY WE WERE ABLE TO NARROWLY AVOID THE TRAFFIC AHEAD WITH WHAT LITTLE BRAKE ACTION I COULD APPLY. WHEN THE ENGINE WAS STARTED AGAIN, THE "CHECK ENGINE" LIGHT CAME ON. AFTER BEING TAKEN TO THE DEALER THE SENSORS WERE REPLACED ON THE TURBOCHARGER AND OTHER UNDISCLOSED WORK WAS DONE TO THE ENGINE. LATELY THE TRUCK HAS BEEN MIMICKING THESE SYMPTOMS.
