They turned off the charger while you were charging??Some will be, some won't. It will be up to the dealership. I've seen the same thing at Nissan dealers. In fact we were once charging at a Nissan dealer. When the shop (but not the dealership) closed, they turned off the charger.
I could see it just being a giant breaker that they shut down at the end of the day and didn't even know the charger was connected. Or the person resonsible for turning it off at the close of the day just wanted to get home himself.Wow. Did you have enough charge to get to your destination or did you have to make another stop?
