The first thread you linked to is about someone who was denied the right to purchase the
optional extended service agreement 50,000 miles later because they didn’t perform the then-required annual maintenance in the first 50,000 miles (which was clearly noted as a requirement in the purchase conditions for the ESA). It has absolutely nothing to do with your initial statement of “existing customers have been denied legitimate claims for battery warranties” - which we can now pretty safely state you completely made up.
Additionally - had you actually read the thread in question, you’d note that Tesla actually conceded and allowed the OP to purchase the ESA in any case.
Extended warranty denied because I did not do the scheduled inspections
The second article discusses the apparently shocking fact that warranty terms change over time.
Setting aside that not being shocking, the article clearly quotes the relevant section of the warranty document that makes your made up claim about battery warranties being denied based on revised terms impossible:
“Any Model S or Model X purchased prior to the effective date specified on the cover page of this New Vehicle Limited Warranty is subject to the applicable Battery and Drive Unit Warranty effective as of the date of purchase.”
Move on, friend. You’re obviously hurt and angry, but that’s no excuse to just make things up.
