Earlier quoted context omitted.
As someone who typically drives cars outside of their warranty period, I don't understand the lack of concern about reliability after your 3rd drivetrain. I suppose if you are leasing the car that is one thing, but with that kind of warranty work I would be extremely hesitant to buy a used Tesla.
The Model S powertrain warranty is 8 years/infinite miles.
I try to run then as long as possible because cars are money sinks.
