Joel, welcome to SCoA.
Sorry that you didn’t find our sandbox BEFORE the dreaded “EV System Workshop - Engine System Off.”
Service countdown or Mileage Minder is not causal as it is days/miles driven and will not create any codes or error messages.
Your “Cheers” may soon change to something more negative as likely your 5 year old 12 volt dropped below minimums and the HV Battery “discharged” leaving you with a sled?
Your “local” ex-smart Center may be able to diagnose but case history is not on your side!
Do keep us in the loop as you endeavor to bring ED back to life...
