NHTSA Complaint #10548119 — 2013 FORD F-150

I TOOK MY 2013 FORD F-150 WITH THE ECOBOOST ENGINE ON A WEEK LONG VACATION DOWN TO SOUTH TEXAS (APPROX. 1200 MILES OR 17.5 HOURS ONE WAY) IT WAS SUNNY AND WARM THE ENTIRE TRIP DOWN AND THE VEHICLE RAN GREAT. HOWEVER ON THE WAY BACK UP TO IOWA IN WAS RAINING AS SOON AS WE LEFT AND ONLY LET UP RAINING FOR 20 MIN INCREMENTS THE ENTIRE WAY HOME. ABOUT 5 HOURS IN WE PULLED OFF THE INTERSTATE TO GET GAS AND EAT. WE GOT BACK IN THE VEHICLE AND PROCEEDED TO GET ON THE ON RAMP AND RETURN TO THE INTERSTATE. I WAS GOING ABOUT 40 MPH WITH SMOOTH ACCELERATION WHEN I GAVE MY TRUCK A LITTLE BIT OF GAS TO MERGE INTO THE 75MPH TRAFFIC. MY TRUCK DID NOT MOVE, INSTEAD IT CONTINUED TO GO 40MPH AND REVVED UP TO REDLINE. I HAD TO LET OFF OF THE GAS COMPLETELY AND PUT MY FOOT BACK ON IT AND SLOWLY CLIMB UP TO 65MPH. THE TRUCK STARTED SHAKING HORRIBLY AND MY CHECK ENGINE LIGHT STARTED TO FLASH. AFTER ABOUT 45 SECONDS THE CHECK ENGINE LIGHT STOPPED FLASHING AND THE ENGINE STOPPED SHAKING. I THEN COULD MAKE VERY SLIGHT SPEED INCREMENTS. I COULD NOT HOWEVER STEP ON THE GAS TO PASS SOMEBODY WITHOUT THE TRUCK REVVING UP TO REDLINE AND SHAKING AGAIN. THIS HAPPENED EVERY TIME I TRIED TO ACCELERATE QUICKLY THE REST OF THE WAY BACK (12.5 HOURS). THE TRUCK RUNS GREAT UNTIL IT IS INTRODUCED TO 70MPH INTERSTATE DRIVING IN HEAVY RAIN FOR LONG PERIODS OF TIME. *TR
