So, this morning, I noticed something strange. After the car warmed up in my ultra-cold climate, the engine turned off to run on EV according to the energy usage display. However, the dash gauge still showed a white line instead of a blue line, suggesting it was NOT being powered by the battery, but by the ICE (which was not "lit up". What could this mean? The pictures are not very good, but I assure you that even though the engine appears "lit up" in the picture, it was not. It was lit up earlier but then shut off, with the power line still showing white.
I have seen this once before, all white gauge in EV mode. I presume this is some type of glitch in the display.
