I only have the '11 service manual but a lot of things are the same from like '07-'11.
The service manual shows that the interlock that locks the trunk or hatch to not work when the doors are locked runs a ground from the trunk or hatch latch through one of the front door latches to get to ground. Driver side if non-power windows, and pass side if power windows; the DOOR latch must be electrically unlocked to enable the trunk latch to work. If the front door is electrically unlocked then possibly a microswitch that did not fully switch to close and you have to positively open the door physically to complete that all the way. I've had that issue with Fords, on those the switch almost closes then goes into a machine gun stuttering on and off repeatedly until the switch fully gets into 100% closed to stop.
When the mechanical linkages the cars use in the doors get dry of lube they do not swing quite as far as when they are lubed well and move easily then. Then they just barely touch any limits rather than fully switching them one way or the other. Often only a few thousandths of movement short will do it. On the Fords I take the latch modules apart and relube them but they are made to destroy to get inside them and I had to figure out a way to break them open to be able to get them back together after done. Couldn't simply spray lube in there like some, the insides were compartmented in 3 sections to completely seal off parts unless the latch is opened up. Lubing those stopped all erratic action and for years and free latch at $150 each. Of course I had to do the work.
I wouldn't be surprised at all to find the Nissan one built the same, but the first thing to do would be to get spray grease and shoot up in there to see if anything loosens up to work better, that might fix it. The pass side door latch is what we're talking about here.
Focus on the pass side door latch as the problem there if the car has power windows. I haven't had any trouble on mine yet but I suspect I will be tearing into the Nissan latches before it is all over.
