NHTSA Complaint #10509838 — 2011 FORD F-150

I HAVE A FORD 2011 FX4 ECOBOOST. WHOLE TRUCK STARTED SHUDDERING AS I WAS GETTING ONTO THE SOUTHWEST FREEWAY. CHECK ENGINE LIGHT WAS FLASHING AND VEHICLE HAD LOSS OF POWER. WAS ABLE TO COAST AND DRIVE SLOW TO THE NEXT EXIT WHERE I PULLED INTO A GAS STATION AND TURNED THE ENGINE OFF. I STARTED THE TRUCK AGAIN AND IT SEEMED OK BUT THE SHUDDERING HAPPENED AGAIN ON THE WAY HOME AND THIS TIME THE CHECK ENGINE LIGHT STAYED ON. TOOK IT TO THE DEALERSHIP WHERE THE CODE WAS PULLED AND THEY REPLACED THE CATALYTIC CONVERTER. SAME THING HAPPENED TO ME (SHUDDERING AND LOSS OF POWER) AGAIN AT 30K MILES 3/4/2013 WHERE THIS TIME THEY REPLACED A IGNITION COIL AND SPARK PLUG. AND A THIRD TIME AT 34K MILES 4/27/2013 AND IT IS BACK IN THE SHOP TODAY. WHEN THIS HAPPENS IT IS VERY DANGEROUS DRIVING ON THE FREEWAY WHEN YOU CANNOT GET THE TRUCK TO DRIVE WITHOUT SHUDDERING AND JERKING ANYTIME YOU GIVE IT GAS. SOMETHING NEEDS TO BE DONE BEFORE ANYONE GETS HURT. THE DEALERSHIP SO FAR HAS BEEN FIXING WHATEVER THE CODE STATES, HOWEVER THERE IS A UNDERLYING CONDITION THAT IS CAUSING THIS TO HAPPEN THAT NEEDS TO BE ADDRESSED. *TR
