The oldest Leaf is like 3.5 years old now. How could you possibly know that the suspension will require a rebuild before the battery goes?
They didn't just pull this battery chemistry out of their assholes, you know. And the suspension isn't based on new principles either, which is my point. They know that rubber bushings will fail. They also know that polyurethane bushings won't (unless subjected to the kind of abuse that would certainly obliterate a rubber bush) and that's why they don't use them. And by "they" I mean automakers, not Nissan.
The cars are designed to be cheap to build, easy to put together, difficult to service (small and inexpensive changes would make service vastly easier on most vehicles) and guaranteed to disintegrate. Cars are just made to fail, and they're made that way on purpose. We have better designs and/or materials for pretty much everything which does typically fail, which simply aren't used. EPDM breather hoses crack and fail, silicone will last damned near forever anywhere but on the sleeve directly connected to my turbocharger. There's a plastic coolant tube between the engine block an the oil cooler on the A8, about two inches long, which always breaks. There's just no reason for it not to be made of Aluminum. Thousand dollar service job to have the oil cooler pulled out. None of this is by accident.
Personally I'm hoping by the time my leaf lease is up, there will be a Tesla model that has the same sort of affordability, as they do not have a dealership network to try and support with these sort of shenanigans.
No, but you do have to pay your yearly contract fee to Tesla if you want to maintain your warranty.
