I'M APRIL OF 2018 THE ELECTRIC TAILGATE ON MY 2017 FORD F-350 STARTED OPENING ON ITS OWN ANYTIME AND ANYWHERE. IT DID NOT MATTER IF THE TRUCK WAS IN PARK OR IN GEAR BUT DID NOT OPEN AT SPEEDS ABOVE 10 MPH OR SO. AFTER GOING TO THE FORD DEALERSHIP IN ELKHART IN. I WAS TOLD THERE WAS NOTHING THAT COULD BE DONE BECAUSE IF THEY UNHOOKED THE WIRING L COULD NOT OPEN THE TAILGATE. I PULL A 5TH WHEEL TRAILER WITH THE TRUCK SO THIS WAS NOT AN OPTION IF L WANTED A TAILGATE. I TRIED TO WATCH THE BEST L COULD BEFORE TAKING OFF TO MAKE SURE THE TAILGATE WAS CLOSED WHEN L WOULD MOVE THE TRUCK. I DID NOT NOTICE THAT IT HAD COME DOWN AGAIN AND MADE A TURN WITH THE TRAILER HOOKED TO THE TRUCK. NEEDLESS TO SAY THE TAILGATE WAS CRUSHED BEYOND USE AND BROKE A TWILIGHT LENS AT THE SAME TIME. AGAIN L WENT TO THE FORD DEALERSHIP IN ELKHART IN AND WAS TOLD THEY HAD NO REPORTS OF PROBLEMS AND THERE WAS NOTHING THEY COULD DO ABOUT IT. THE TAILGATE HAS NOT BEEN REPLACED DO TO THE FACT L AM SURE THERE IS STILL AN IS SURE.
