I don't want to take over the thread, but I'm also having intermittent locking issues with my 2016 Titanium. Sometimes the tailgate starts to open but won't, it seems to catch and will not release fully. Other times it's completely dead, all switches will not open it. No clicks, nada. Then if I wait about 20 min it miraculously opens up normally. Also, when closing it there usually is a slam, then a click as it latches. Often there is the usual slam and no secondary latch click. Does this sound like a defective latch assy? I might just try it for $60 its money well spent.
