I have a 2013 AWD version and my Power Gate seldom ever works without issues. Started with it opening about 10 inches and then shutting. Then if it did open all the way, when I clicked any buttons fob, inside door button, or dash button, it would drop about 10 inches, stop and then open again. This started happening every time I ever used it. I took it to the dealer when it came down on me and knocked groceries out of my hands onto the ground. It was suggested that I replace both struts which I did. This seemed to solve problem for about 1 day. Next day it happened again. Its in the shop for the fourth visit now with no success. Perhaps Ford should discontinue this feature as from all the forums like this one show, its a LAME DUCK SERVICE!
