It seems to happen when I try to connect to a high speed public charging station that appears to be functional, but actually isn’t (I’m looking at you, EA.)
This particular instance happened when I connected to an EA station that wasn’t operating correctly.
I eventually disconnected from that charger and reconnected to another at the same EA location, where I then encountered an apparent payment system error:
… and the delayed text notification problem was noted on the same EA visit.
Concurrent with the errors on the instrument display, the circular lighted status indicator inside the charging access door on the car shows solid red, and it takes some patience and hope before the charging cable is eventually released from the car.
(Which begs the question: there must be a way to force the car to release the cable, but I haven’t researched how. Anyone know?)
