Did you check the 12 V battery?
The symptoms could be explained by a weak 12 V battery. Whenever an i3 is being actively charged (as opposed to just plugging in an EVSE with a fully-charged battery pack), the 12 V battery is being charged also. So a while after each charging session, your 12 V battery's voltage is high enough for the car to function correctly. However, after sitting for a while, the 12 V battery discharges to the point where errors are set and thinks don't work correctly.
Of course, the problem could be something totally different…
Art, I haven't put a meter on the battery yet, but the last one that happened was right after being plugged in overnight on the charger. I know I'm not supposed to trust my display, but it is showing my 12v battery was fully charged when it happened last.
I'll ask the dealer if they put in a new battery since this is a CPO. If not, I'll see if I can get them to put one in based on this issue.
