NHTSA Complaint #10817447 — 2012 FORD F-150

WHEN DRIVING IN HUMID OR WHEN MOISTURE IS PRESENT SUCH AS RAIN OR MIST THE ENGINE SHUDDER, SHAKES, MISSES AND EVEN SHUTS DOWN WHEN QUICKLY ACCELERATING. I HAVE HAD THE ENGINE COMPLETELY LOOSE POWER WHEN MERGING ONTO FREEWAY IN HEAVY TRAFFIC. I TOOK IT TO THE DEALER ONCE WHEN IT WAS UNDER WARRANTY. THEY SAID THE CATALYTIC CONVERTER NEEDED REPLACED. OF COURSE I DIDN'T DRIVE IN HUMID OR RAINING ENVIRONMENT CONDITIONS AGAIN UNTIL THE WARRANTY RAN OUT. I HAVE EXPERIENCED THE ENGINE SHUT DOWN AT LEAST 4 TIMES SINCE I BOUGHT THE VEHICLE NEW. ALMOST CRASHED TWICE WHEN PASSING OR MERGING WHEN ENGINE SHUT DOWN. THE DATE ENTERED BELOW WAS THE LAST TIME THE PROBLEM OCCURRED. FIRST TIME WAS MARCH 2013 WHEN VEHICLE HAD ABOUT 16,000 MILES.
