I like freebies as much as the next guy -- but there would be HUGE implications for announcing such a program.
--Service plans already bought?
--Retroactive application?
--Customer expenses already paid?
And that's just getting started. While it could certainly be argued that we bought the cars and should make peace with the terms of our agreements, the truth is we know the Tesla owner crowd would scream bloody murder if any such announcement was not accompanied by full refunds (of the service plans) and universal retroactive application.
If Tesla resisted, there would be an overnight glut of used Model S available as anyone with the ability to would take the hint and upgrade to an eligible new car-- which would be disastrous for the "guaranteed value" cars Tesla leased (among others).
Is it even feasible economically to give people lifetime warranties? It sounds awesome but honestly, I want to make sure Tesla keeps making money. I also don't think its fair to make a company offer this when nobody else is. It just sounds like they would be punishing themselves simply because they sell EVs.
