same thing has happened to my Libby. After about two weeks, however, the liftgate now will not unlock. I cannot even open my tailgate. I am taking it on a trip next week and it would be great to access my suitcases and all from the rear side of the vehicle, not through the back doors with the seats down. I also tend to carry tools and furniture and hockey sticks and I have not been able to do that easily either.
I am going to try the "emergency access" button/lever/whatever for now before I take it in. Unless anybody has any advice or ideas on what is wrong.
