I have an Ariya and love it. In general, I agree with the other comments. I would ad that sometime in 2024, we'll be able to get a NACS adapter to use Tesla superchargers beyond the Magic Dock (I think closest ones may be up in NY? Can see map here).

Service at my dealer made a joke about oil changes but yes I agree they don't seem to know a lot. Nissan USA trying to somewhat skip dealers on sharing info.

How near the destination are you looking? Are there any Electrify America, EVGo, Shell Recharge, etc. stations where you can charge to get to your final destination? You might not need a level 3 close to where you are going if there are other charging options while you are there.

For example, if you find a level 3 station 100 miles out, could you then have enough charge to get to your final spot and then even back to that charger on your way back if need be?

This map shows Tesla superchargers with the CCS "Magic Dock". https://www.plugshare.com/map/tesla-ccs-locations

Very few of the Tesla stations have the CCS adapters yet. The normal supercharger plug will not fit your car.

Have you tried using PlugShare or ABRP to identify chargers and/or routes that work for you?

I have a Nissan Ariya (2023) and hoping to make a longer trip where I will need to charge away from home. The only Level 3 charger I have found near my destination is a Tesla supercharger station. I can’t figure out if I will be able to charge my Ariya at that station. It looks like Tesla opened up to CCS chargers, which my Ariya apparently is, but it isn’t clear if ALL tesla supercharger stations allow the CCS charging or only some. Does anyone know?
And before you ask: my Nissan dealer is clueless. They keep trying to offer me free oil changes!
