My symptoms:
Trunk hatch would not operate from remote, rear lever, or cabin button. The hatch would only release by using the valet key to perform the emergency hatch release manually from inside the vehicle. Once released, the remote, hatch buttons, and cabin button operated the hatch just fine, but once closed, the hatch again wouldn't release.
Replacement part:
204-740-13-00 Lock Actuator
