I guess it's down to two possibilities: bad BMS or bad cells. And as I've said, I don't think we've ever seen bad cells manifested by higher
voltages... How about it folks? I just woke up, and my brain is mushier than oatmeal. Is this the first time we've seen this? If the BMS is glitchy "locally" rather than "globally" would that manifest like this?
Don't open the battery yourself. That will void the warranty.
I just checked my 2011 Leaf (with a 2015 pack and 2015 BMS). At 72% SOC, I'm showing the average voltage to be 4.021V, minimum 4.017 and maximum 4.026 (9mv min/max). I do not believe your cells are overcharged.
It's crazy that they won't cover this under warranty. This is clearly a failure of the lithium ion battery. Do you have to call the EV help line for coverage info? Can you just work through the dealership? Is the dealership referring you to the EV help line for something?
Hey Nissan: This is why Tesla is eating you alive. They've built plenty of faulty stuff, but they back it up and fix the issues.
I would get a video of the behavior of your car when it goes into turtle suddenly. I would take a copy of the video into the dealership along with a printed copy of the warranty booklet, and tell them this is a safety issue resulting from a faulty battery. If they refuse, I would ask which specific criteria excludes this from being a warranty issue. Get everything in writing.
I would then take the car to another dealership in your area with a good reputation. See if they can somehow get something done. If not, I would get the rejection in writing from them as well. It's really absurd--I've seen a number of people post on the forums with problems and symptoms very similar to yours, and they got the battery repaired in days.
If you get rejected at all dealerships, you have three options:
1) Sue Nissan
2) Sell the car
3) Repair or replace the battery pack yourself. You could buy a new pack from Nissan for $5500, or replace it with a different pack from a junkyard, or replace the cell. Doing this will void the warranty.
I've seen a post from a guy who went through similar conditions to you. It was hellish, and he did end up suing. He came back to post that the issue was "resolved" and he was "happy with the outcome" and would have "nothing more to add". (i.e. he settled and got what he was looking for).

LITHIUM–ION BATTERY COVERAGE
The Lithium-Ion coverage period is 96 months or 100,000 miles, whichever comes first. This warranty covers any repairs needed to correct defects in materials or workmanship subject to the exclusions listed under the heading WHATISNOTCOVERED. This warranty period is 96 months or 100,000 miles, whichever comes first.
This warranty does not cover damage or failures resulting from or caused by:
Exposing a vehicle to ambient temperatures above120F (49C) for over 24 hours.
Storing a vehicle in temperatures below -13F (-25C)for over seven days.
Leaving your vehicle for over 14 days where the lithium-ion battery reaches a zero or near zero state of charge.
Physically damaging the lithium-ion battery or intentionally attempting to reduce the life of the lithium-ion battery.
Exposing the lithium-ion battery to contact with a direct flame.
Immersing any portion of the lithium-ion battery in water or fluids.
Opening the lithium-ion battery enclosure or having it serviced by someone other than a Nissan LEAF certified technician.
Neglecting to follow correct charging procedures. Use of incompatible charging devices. Consequential damage caused by the failure to re-pair an existing problem.
GRADUAL CAPACITY LOSS
The Lithium-ion battery (EV battery), like all lithium-ion batteries, will experience gradual capacity loss with time and use. Loss of battery capacity due to or resulting from gradual capacity loss is NOT covered under this warranty beyond the terms and limits specified in the LITHIUM-ION BATTERY CAPACITY COVERAGE above. See your OWNER’S MANUAL for important tips on how to maximize the life and capacity of the “Lithium-ion battery.”
