NHTSA Complaint #10749728 — 2011 FORD F-150

WHEN THE TURBO BOOST IS 11PSI MISFIRING BEGINS - NO AFTER MARKET ENGINE PROGRAMMING. IF TURBO DEMAND IS NOT REDUCED, OR IS INCREASED THE ENGINE LIGHT WILL COME ON AND THE TRANSMISSION WILL BE DISENGAGED - 'LIMP MODE.' ON THE DATE CITED, THIS HAPPENED NO LESS THAT 3 TIMES. LOCAL HUMIDITY WAS 50-70%, AS I RECALL, AND THERE WAS NO RAIN. I HAVE EXPERIENCED THIS MULTIPLE TIMES WITH LOCAL HUMIDITY NOTED AT 50 %. MY EXPERIENCE IS THAT THE MISFIRING WILL OCCUR ANYTIME TURBO PSI EXCEEDS 11, WHETHER TOWING OR NOT, THOUGH TOWING WILL BE MORE APT TO ENCOUNTER 11PSI. MY TRAILER IS WITHIN ALL TOW LOAD LIMITS FOR MY TRUCK, AXLES AND TONGUE, PER FORD'S RV & TRAILER TOWING GUIDE. MY FIRST EXPERIENCE WITH THE TRUCK GOING LIMP WAS JUNE OF 2014. I PULLED THE TRUCK TO THE SHOULDER NEXT TO A GUARD RAIL AND CALLED FOR TOWING. THE LOCAL FORD DEALER SAID THAT THERE HAD BEEN A #3 CYLINDER MISFIRE AND A MOMENTARY HEAD OVER-TEMP WAS - WHICH TRIGGERED LIMP MODE. I HAVE REPORTED THE MISFIRING TO MY DEALER, AND WITH FORD'S CUSTOMER SERVICE. THE DEALER SAYS FORD HAS NOTHING LISTED FOR MY TRUCK OR THE ISSUE. I TOLD CUSTOMER SERVICE AND MY DEALER THAT THERE IS PLENTY OF INTERNET TRAFFIC ON THIS ISSUE. ASIDE FROM THE TECHNICAL SERVICE BULLETIN IMPLEMENTED TO PUT A LARGER AIR SHIELD ON THE INTERCOOLER (CAC), DONE TO MY TRUCK IN 2014 AS A RESULT OF MY EXPERIENCE, THE ISSUE STILL EXISTS. IT WOULD SEEM TO ME THAT FORD HAS NOT ENGINEERED A WATER SEPARATOR TO THEN DRAIN OFF DEVELOPED WATER FROM THE CONDENSATION PROCESS BEFORE IT IS INGESTED INTO THE CYLINDERS. INGESTION OF THE WATER INTO THE CYLINDERS WOULD CAUSE A SPARK MISFIRE, AS WAS SUGGESTED TO ME BY A FORD MECHANIC. MY VEHICLE IS STILL UNDER A FORD ISSUED EXTENDED WARRANTY, AS A RESULT OF A SEPARATE TRANSMISSION ISSUE. GOD FORBID THIS OCCUR WHILE TO SOMEONE TOWING ON A TWO LANE ROAD WITH NO SHOULDER!
