A couple of things. The NAH system is the same as on the Long Tested Prius. Sure they put it in a heavier car and placed the batter differently, but its still the same Hybrid System.

That being said, I doubt they are hiding anything. In order to get paid for Repair Work and Diagnosis time, they must submit invoices and that is recorded against the cars Vin. #

These cars are new to Nissan so I am not surprised that only one person is certified to touch it. When a battery drains down, it will cause major problems. It will screw with the computer system.

Finally, the NAH WILL re charge Hybrid battery when coasting down hill. Especially steep hills! I don't think it is a design flaw because then we all would be having the problem. I don;t doubt your problem, just think there is another reason behind it and not a design flaw.
