I believe that it did kick on at 2 bars, but I was going 75 or 80 with the ac on up a very steep hill. I think that it kicked on at 2 bars, quickly went down to 1 bar, then screamed like crazy, I cut off the ac, slowed down, put on the hazards; and hit ev charge. The hill continued to be in front of me, and I went through the last bar quickly.This does not sound like normal behavior to me. The car should have switched at two bars, not one. It should have had enough power gas only to go more than 15 mph uphill. Finally - it should not have bricked.
I daresay you have an warranty repair due you for the electric drive train, probably multiple components including the computer, since, IIRC, that warranty is for 10 years.
