Guys. I think it doesn't really matter to most of us the specifics of Kevin's car or case. What should matter is that Tesla should specify with regard to the Model S and future batteries, Model X, Model 3, AND the purported 400 mole battery an actual expected degradation.
FURTHERMORE, I would like it if they would provide some warranty based upon that guideline for replacement under warranty AND a price list if the customer wishes to get a pack that is "newer" or refurbished to a higher capacity than their own AGED/DEGRADED battery pack.
The Battery Swap demonstration over a year ago took some of these thoughts into consideration over a year ago.
Though I bought into the hype of the Infinite Mile battery warranty for my S85, I am now questioning the disingenuous nature of that marketing and it's specific exclusions. However, as an owner, if they choose not to do something about it, I'm just stuck until my car's range is "unusable". Which in my case becomes the range of a BMW i3 BEV (i.e. A very long time).
Sadly, the topic for me remains as a request for Tesla to clarify and enhance the future battery warranty AND, if possible, the Roadster Warranty for e different classes (those that are original owners who may still be under a warranty and those of us who are under the CPO warranty, as well as those that are no longer warranted).
(ALL Caps because I can't figure out bold on this client)
