Reporting error codes for specific parts of the battery, errors in the coolant system, error codes for specific sensors throughout the vehicle, etc

Or considering basically all EVs I've seen have some big screens rather than gauges perhaps having the ability to put the vehicle in a diagnostic mode that will display error codes and allow you to check on specific sensors (like read the heath of each individual battery cell for example) without the need for an external device to check

Basically having the ability to fix something that we bought ourselves rather than having to go to the dealership to get it fixed and hope that they'll still service a vehicle of whatever age I bring in
