Well, I am not going to court, I am going to work through the process laid out by Nissan.
Re the Venn diagram, that is one way to describe a rigorous analysis of the warranty language provided by Nissan. I do believe rigorous analysis of warranty language will be welcomed by everyone, especially if it includes helpful images. We are all well-meaning people in this. The Nissan EV technology in the car was relatively new in 2013, and is obviously still evolving today. My take is that this is a rare or very rare fault, that no one currently in the loop has had experience with it, and we are all patiently working towards a mutually agreeable outcome, and I am very grateful to lean on the expertise around here
. Covid 19 has made things generally odd as well. I have been driving Nissan vehicles since my first three Datsun 510s and I trust the quality of the engineering--that is why I currently have two of them in my driveway.
I appreciate that my previous explanation of what the 2013 Leaf Warranty is saying could be more clear, so here is a simpler version working directly with quoted line verbatim from page 7 and page 8 of the 2013 Leaf Warranty. Quoted line and words are in italics.
Quote 1 from the LITHIUM-ION BATTERY CAPACITY COVERAGE on page 8:
If possible, the Lithium-Ion battery components will be repaired or replaced, and the original Lithium-Ion battery will be returned to the vehicle. What this defines is two things: first, the
Lithium-Ion battery is a single item, original to the vehicle, which is removed and replaced from/to the vehicle; second,
Lithium-Ion battery components are more than one items that are components of the
Lithium-Ion battery. Corollary, since the
Lithium-Ion battery is a single item removed from the vehicle, and repairs are made to that prior to return to the vehicle, then
Lithium-Ion battery components are contained by (are a sub set of) the
Lithium-Ion battery, and the
Lithium-Ion battery must be the whole unit including the
components inside. The language does not actually specify that the
components are inside the shell, but there is no other rational options for where those components could be. If anyone can convincingly parse this warranty language otherwise, love to hear. From my viewpoint, the warranty has clearly defined the single battery and the multiple components.
Quote 2 from the LITHIUM–ION BATTERY COVERAGE on page 7:
LITHIUM–ION BATTERY COVERAGE The Lithium-Ion coverage period is 96 months or 100,000 miles, whichever comes first. Above it was established that the
Lithium-Ion battery must be the whole unit including the
components inside. Again, if there is any real world way to re arrange the known elements of the battery and the known language of the warranty, please do so. So the LITHIUM–ION BATTERY COVERAGE 8 year warranty applies to the battery.
What the warranty does is provide an internally and externally consistent definition for the battery and its components. It also provides an 8 year warranty for the battery. There is additional consistent supporting language and reasoning in these two warranty sections for those definitions (which I wont go into unless asked because I think I have used up all my MNL ink for awhile), and there are zero (that I can see) alternative explanations.
