" sealed for life". is a marketing phrase, not a auto engineers favorite expression.
Many cars have "sealed for life" transmissions with no obvious drain/fill features., but most auto mechanics agree that the "life" term usually extends as far a the "life" of the warranty !
Common practice through out the real auto mechanic world to change those sealed in fluids occasionally to extend the "life" period !.....But, yes, its no big deal either way especially if it saves a few hundred $$$s on dealer service charges.
Im an Engineer by profession, and as soon as someone suggests reducing maintenance periods, time, or costs, my ears perk up. Its usually a cost saving effort or a sales pitch from an equipment supplier, and i have been burned by this more than once
Servicing on most modern cars is mostly inspection and checking, rather than repair or replace, so i guess i am a little concerned that some non tech owners could be using a car with leaking fluids, shot shocks, damaged tires, dead lights, loose suspension bolts ( it has happened to me !) etc.
I know there is no ICE to change oil, filters, belts , etc, but the rest is a typical car (and a complex one) so i an surprised there is not at least an annual "inspection" recommended !
As an aside, it is amusing to think that possibly the first thing that will fail on this Electric car ...is the Battery ..12volt !
