My rear trunk suddenly stopped opening. UI indicates it's open but it's definitely fully closed. All methods to open it electronically (key fob, touch screen, and trunk button) result in 2 beeps but no latch release or movement. The emergency release cable has no give (I.e. Doesn't move at all even when pulling on it with pliers). Pulling on cable while lifting gate manually also doesn't help. Reboot didn't help. Any other thoughts?
