THE FOLLOWING INCIDENT HAS OCCURRED TWICE. THE ONLY COMMON FACTOR I CAN IDENTIFY IS A GREAT DEAL OF RAIN PRIOR TO THIS. MY TAILGATE HAS OPENED TWICE BY ITSELF. WHEN THIS OCCURS, IT TAKES SEVERAL MINUTES TO CLOSE. I'VE HAD THE DEALER LOOK AT IT. THEY CLAIMED TO HAVE VIRTUALLY TAKEN THE WHOLE THING APART, AND CANNOT FIND THE SOURCE OF THIS PROBLEM. *TR
