NHTSA Complaint #10607378 — 2011 FORD F-150

AS I WAS MERGING ONTO THE HIGHWAY, I HAD TO ACCELERATE TO AVOID A SEMI WHO WAS APPROACHING IN THE RIGHT LANE. I HARD ACCELERATED, BUT THE TRUCK STARTED SHAKING AND THE CHECK ENGINE LIGHT BEGAN FLASHING. I HAD LOST ALL ACCELERATION AND WAS FORCED TO PUT MY FLASHERS ON AND MERGE TO THE BREAK-DOWN LANE TO AVOID BEING RUN COMPLETELY OFF THE HIGHWAY. THE TRUCK SHOOK VIOLENTLY WHILE IN 6TH GEAR AND I HAD TO MANUALLY SHIFT TO 5TH GEAR TO STOP THE TRUCK FROM VIBRATING APART. LESS THAN 10 MINUTES LATER (WHILE DRIVING DOWN THE HIGHWAY IN 5TH GEAR) THE CHECK ENGINE LIGHT TURNED OFF AND THE TRUCK WAS ABLE TO BE SHIFTED BACK INTO 6TH WITHOUT ANY VIBRATION. THIS LACK OF ACCELERATION IS EXTREMELY DANGEROUS AND HAS HAPPENED MORE TIMES THAN I CAN COUNT. ABOVE WAS ONLY AN EXPLANATION OF THE LAST OCCURRENCE. THE TRUCK HAS BEEN SERVICED (UNDER WARRANTY) WHERE ISSUE WAS DISCUSSED WITH FORD, BUT THEY WERE UNABLE TO "REPRODUCE" THE PROBLEM... *TR
