NHTSA Complaint #10549406 — 2012 FORD F-150

WAS DRIVING ON A TWO LANE HIGHWAY AT APPROX. 60MPH AND WHEN I WENT TO PASS A TRUCK, AS I ACCELERATED AND GOT ALONG SIDE THE TRUCK, MY ENGINE LOST POWER SO I COULD NOT PASS. I WAS LEFT IN A VERY VULNERABLE POSITION ALONGSIDE THE TRUCK AND HAD TO BRAKE TO DECELERATE AND TUCK BACK IN BEHIND THE TRUCK. THE WEATHER WAS CLEAR, TEMPERATURE ABOUT 60 DEGREES, AND LUCKILY NO ONCOMING TRAFFIC BUT THERE WAS A VEHICLE BEHIND ME (AND LUCKILY THAT DRIVE SAW MY BRAKE LIGHTS, BACKED OFF AND ALLOWED ME TO TUCK BACK IN BEHIND THE TRUCK). AN ACCIDENT COULD HAVE RESULTED. AFTER GETTING BACK BEHIND THE TRUCK MY VEHICLE STILL HAD POWER BUT HAD A SHUDDER IN THE DRIVETRAIN WHILE UNDER LOAD (LIKE UPHILL, OR DRIVING DOWN THE HIGHWAY AT NORMAL HIGHWAY SPEEDS, BUT NOT WHILE COASTING). I HAVE NOT TRIED FULL THROTTLE ACCELERATION AFTER THIS INCIDENT AND HAVE DRIVEN THE VEHICLE SPARINGLY. CALLED THE FORD DEALER SERVICE DEPARTMENT AND HAVE AN APPOINTMENT TO BRING THE VEHICLE IN. WHEN THE ENGINE STALLED IT WAS JUST LIKE SOMEONE TURNED OFF THE KEY, NO POWER BUT AT LEAST PARTIAL POWER WAS REGAINED AFTER I LET OFF THE THROTTLE. THE ENGINE IS THE 3.5 LITER ECOBOOST. *TR
