What does it mean if:

By "first 2 charging lights" you mean the charge indicator (three blue LED lights) on the right upper corner of the dash? If it was blinking with 2 lights on, it should have had a partial charge in the battery. I have not done it myself, but if you interrupt charging by opening a door while charging, you might be correct that it will not resume charging after you close the door.

I only do schedule charging at night for very early morning departure (5 am), so I almost never open the door during charging. However, I have had an incomplete charge several times over the last two years. It is not frequent occurrence nor repeated events, I attributed those incidences to random error either on the car, EVSE, or electrical line.

 

I've opened doors while charging a gazillion times. It just shows on the dash how much time is left (that's why I opened the door) and continues to charge.

If it's on a schedule and should be charging but isn't, are your clocks set correctly? There's the one in the dash and the one in the big display. As I understand it, the one in the big display is just for nav, but I'd check both just to be sure.

 

And be sure that you have AM/PM right. The one in the dash is the one used by the timer.

 

Good point!!

 

If ambient temps are cold enough, Prime will delay charging while the heaters warm the pack.
even without perconditioning activated
It was very confusing the first few times it happened to me.

The interrupting of something when you opened the door, sounds to me like the Prime was perconditioning, which is also related to heating things in the car when it cold outside.
