I agree that probably your case should be dealt with someone higher in Nissan USA. The dealer may be trying is best to solve the case but I think this is a problem that Nissan Engineers should take a look. Driving two cars with two different drivers and relying in the GOM to check the battery capacity is not a reliable method.
In your logs the gids seem to be increasing significantly from October, do you notice an inprovement in range? Any Turtle to 100% recent kWh at the wall measurement to check if the capacity is really higher?
If I was in your position I would write a letter to Nissan (probabably with the help of a lawyer) describing the problem, and saying that 80% of the capacity 10 months after purchase is not acceptable and implying that you notice this lower than expected range since the beginning (to imply that this is NOT a gradual capacity loss). I would also explain that I would be using all the legal options available to resolve the issue, with all the bad publicity this would give to Nissan. The FUD spreaders would love this story (one broken ICE is bad luck, one defective battery means all batteries are bad), so I hope Nissan ears you.
