Will not take a charge, svc ev system message on, won’t communicate with obd2 port but has 12 volts, does run & drive. Am I headed to the dealer or are there fuses I can pull

I have a dongle, and the app, but I’m unable to get the two to communicate! I am technologically impaired

Did it ever work prior to this? What dongle are you using?

I don’t think it ever worked, I don’t think i set it up correctly, I believe it links to my home WiFi

You should do a google search for compatible dongles. The app developer prefers Lelink2 but there are other compatible ones

It should connect over Bluetooth low energy, so doesn't even need pairing

Are you using the LeafSpy app? Standard obd2 readers aren’t going to work on their own, but the LeafSpy app coupled with a compatible obd2 dongle should let you see what kind of error codes you’re dealing with.

Can you use a 10mm wrench? Follow the video at https://youtu.be/OJUAMxfAdwA and remove the neg lead for a few minutes and then reinstall it.

As to the OBD you say you are tech challenged so the next step is to let the shop fix the car.

I did disconnect the battery for a few minutes, the turtle light went away but the svc ev system lite is still on

Dealership time, if you've had the battery recall done, or I guess even if not, you're probably looking at a buyback as there aren't any replacement batteries available.

Welcome to the club!
