Most likely a bad actuator, but could also be fatigued wires in the umbilical connecting the door to the car. The umbilical rubber is just grommeted and pulls loose at both ends, it's worth peeling it back and inspecting the harness for tiny splits and breaks before assuming the actuator is bad. This is how the umbilical comes loose...
...and this is the sort of damage you're looking for...
If you find a problem, replace the door harness. Every so often the factory twists a door harness opposite the natural coiling direction of the wires, and fatigue is the result. For whatever reason, it's more common on gen2 Rogues than other models. Since the whole bundle will be fatigued, any repair you make is pretty much guaranteed to cause failures elsewhere in the bundle, so it won't last. If everything checks out, then you can be pretty confident it's just a bum actuator.
