According to the manual, the first service is due at 7,500 miles (we I am quickly approaching). I plan to take my vehicle in because I want to maintain all of the warranty. It looks like they primarily will just be inspecting most of the systems but I know it is going to be due for a tire rotation and balance. We also have a Leaf and to date when it has gone in for it's scheduled maintenance appointments they haven't tried to upsell me on anything and have only performed the typical things (tire rotation, battery check up, inspect systems, etc. - I change my own cabin filter and they have a note of that in the system so they have never asked).
I too was curious, as most people are, about maintenance. I saw the page with all the "I"'s on it and that's exactly why I bought the car. I just want to drive the damn thing, not take shuttles to work with strangers so that they can turn wrenches for 2 hours and charge me $599. Cabin filter (which I hope I can do myself) and fluids are about it. I drive it easy, so I suspect the brakes could go for a long long time.Other than DIY stuff (e.g., topping off fluids, maintaining tire pressure), there's not much to do. From the maintenance section in the manual, it looks like--even if you had a dealership with personnel who knew what to do with the EV model--the most they'd likely do would be check off a bunch of "inspection" boxes, replace your air filter, and then try to upsell you on tire rotation/balancing, etc.
