I wouldn't be concerned about the recall work. One can get it done for free.
Do look at the build month on the driver's side door sticker. I shudder at their mention "SUPER CHARGING port".
There are 3 plug incompatible DC fast charge standards in the US:
1) Tesla Supercharger (North American plug)
2) CHAdeMO (which they Leaf can be equipped with)
3) SAE Combo aka J1772 CCS aka Combo1 of CCS
No non-Teslas can be plugged into Tesla Superchargers.
One should try to find out where the car resided before (e.g. via Carfax and/or Autocheck) to see whether 11 bars makes sense. For me, Carfax provided more clues/info on the used '13 Leaf I bought in July 2015.
