NHTSA Complaint #11174972 — 2011 FORD F-150

TRUCK WILL HAVE SEVERE INTERMITTENT STUMBLE/MISFIRING ON ACCELERATION FROM 45MPH+ IN HUMID, WET OR DAMP CONDITIONS. THE VEHICLE SHUDDERS VIOLENTLY, BOGS DOWN, AND CHECK ENGINE LIGHT FLASHES EVENTUALLY BECOMING A SOLID ENGINE LIGHT. THIS INVOLVES THE ENGINE SHUDDERING WHEN THERE IS ACCELERATION AT HIGHWAY SPEEDS; THIS IS VERY DANGEROUS WHEN TRYING TO PASS VEHICLES AT HIGHWAY SPEEDS. HAVE MY SPARK PLUGS AND COILS REPLACED AFTER THE FOLLOWING HAPPENED IN DAMP AND WET WEATHER CONDITIONS. MAKE YEARS SEEM TO INVOLVE 2011-14 ECOBOOST TRUCKS. FROM THOUSANDS OF FORD FORUM POSTS, THE TRUCKS HAVE AN INTERCOOLER CONDENSATION PROBLEM THAT IS CAUSING POOR PERFORMANCE AND SPARK PLUGS/COILS TO FAIL EARLY. WATER AND OIL VAPOR/RESIDUE CONDENSATION IS BEING SUCKED INTO THE ENGINE. PEOPLE HAVE HAD TO TAKE IT UPON THEMSELVES TO FIND A SOLUTION BY DRILLING A 1/16' HOLE IN THE LOW POINT OF THE INTERCOOLER DRIVER'S SIDE TO DRAIN OIL/WATER CONDENSATION/RESIDUE OR INSTALL A $400-$500 OIL CATCH CAN SEPARATOR WHICH FORD SHOULD BE OFFERING TO OWNERS WITH THIS PROBLEM. FORD SHOULD OWN THIS PROBLEM AND ISSUE AN APPROPRIATE FIX LIKE THE OIL CATCH CAN INSTALLATION OR CONFIRM WITH ITS OWNERS THAT IT IS OK TO DRILL A WEEP HOLE IN THE INTERCOOLER. NOT THE CHEAP FIXES I HAVE SEEN LIKE TSB 13-8-1.
