You mean the one called "Battery and Drive Unit
Limited Warranty" that has specific conditions and exclusions? Misrepresenting and utterly ignoring the specific black and white terms of the warranty is a common theme in this thread. It will not serve your legal interests.
Reading the articles on lithium plating and other battery effects show that lithium plating is a common and known condition caused by usage of the battery especially under certain environmental conditions which would explain why some batteries have it and some do not. But it is speculation --a theory -- and I never represented that it wasn't. It is also just a placeholder for any other condition caused by wear and detected as condition Z trigger levels.
Airbags are distinguishable as a manufacturing defect and their warranty doesn't specifically exclude wear so that isn't a condition of the warranty that needs to be satisfied. Condition Z may or may not be a manufacturing defect. Based on current information I would bet that condition Z is due to wear rather than a defect but that remains open to intelligent discussion if such is possible.
It was.
No. the argument just points out that if condition Z is caused by wear (any kind of wear, li-plating or otherwise) it isn't covered, but if it is a manufacturing defect it is covered.
I'm just reading and interpreting and applying the terms of the warranty to the facts as they appear, and are likely to be further developed. The benefit of this is explained by
@tomas -- but will see the benefit, others will not.
Indeed.
Except the factual scientific answer to the question of what is condition Z directly bears on the legal question of whether the effects of condition Z are due to a defect, or wear, and thus covered, or not.
the supporting authority was directly about the limitations and exclusions in a written express warranty. But interesting point re consumables. Like tires, batteries are known to exhibit wear over their lifetime. In both cases that wear is expressly excluded from the warranty, except the Model 3 batteries have a bottom limit on the level of wear that is not covered. Model S/X batteries do not.
