NHTSA Complaint #10481252 — 2011 FORD F-150

MY TRUCK IS EQUIPPED WITH THE ECOBOOST 3.5L ENGINE. TWICE NOW I HAVE ATTEMPTED TO ACCELERATE AND HAD THE TRUCK LOSE POWER AND SHAKE VIOLENTLY, CREATING A VERY DANGEROUS SITUATION. THE FIRST TIME WAS ATTEMPTING TO PASS ANOTHER VEHICLE. WEATHER CONDITIONS WERE WARM (75 DEGREES F) WITH LIGHT RAIN. I PULLED OUT TO PASS AND ATTEMPTED TO ACCELERATE WHEN THE TRUCK SUDDENLY ACTED AS IF THE GAS WAS SHUT OFF. IT THEN BEGAN TO SHAKE AND SHUDDER VIOLENTLY AS IF THE REAR AXEL WAS BEING RIPPED FROM BENEATH IT. I WAS ABLE TO FALL BACK BEHIND THE VEHICLE I WAS ATTEMPTING TO PASS, OUT OF THE WAY OF ONCOMING TRAFFIC, AND PULL TO THE SIDE OF THE ROAD. AFTER SHUTTING OFF AND RESTARTING THE TRUCK, IT SEEMED TO RUN NORMAL. THE DEALERSHIP SERVICE TECH INSPECTED THE TRUCK AND STATED IT IS A PROBLEM FORD IS AWARE OF (IN WET CONDITIONS), BUT HAS NO FIXES. THE SECOND TIME I WAS ATTEMPTING TO ENTER THE INTERSTATE FROM A REST STOP INTO A SINGLE LANE CONSTRUCTION ZONE. THE WEATHER WAS COOL (45 DEGREES F), DRY AND SUNNY. I ATTEMPTED TO ACCELERATE TO ENTER THE HIGHWAY AND THE TRUCK ACTED AS IT DID ON THE FIRST INSTANCE. I WAS FORCED TO PULL OFF OF THE LANE BETWEEN TWO LARGE CONSTRUCTION PYLONS IN ORDER TO AVOID BEING STRUCK BY A TRACTOR/TRAILER. THE SUPPLIED DATES, MILEAGE AND SPEED WERE FROM THE MOST RECENT INCIDENT. *TR
