I am pondering getting an electric vehicle (a VW e-Golf, which is strongly rooted in the Golf "platform", just swapping the motor), and one issue amongst many is how to proceed with the maintenance. I do not have a good branded shop close by, and driving to the next brand shop to get routine (or even non-routine) maintenance would add considerable hassle. Let's ignore the issue of "voluntary warranty" (the kind that they use to force you to use their own shops) at the moment.
My naive understanding is that in an e-car, obviously the drive train is different; but I would assume that the e-motor is much simpler/self-contained than the whole gas-motor/transmission/light machine/oil/belt/...-shebang, and I would also assume that aside from the drive train, the rest of the car (in this specific example, which is based on a completely run-of-the-mill base model which should be well-known to most mechanics in my country) should be more or less the same.
Is that true? Do e-cars need "special" maintenance (regarding the "e" part) that makes it a specialist job? I assume that the battery and the motor are closed systems anyways, which may be checked through their control units, maybe, but never actually opened by any mechanic during routine maintenance. There should simply be nothing to do.
If this is correct, I could easily trust the car to my local non-branded repair mechanic; he would be able to detect errors in the motor by reading out some onboard unit (as it's done in old-fashioned cars anyways, these days), and if something bad happens, I would then, and only then, go to the branded shop.
Is that assumption correct? Or are these things more complicated than that?
