Plug into a supercharger, and it seems to take forever (well 30 seconds) before charging starts. The display just tells me it's getting ready to charge. At home, it starts in perhaps 5-10 seconds. And, maybe I'm imagining things, seems like for the past year it didn't take so long for the supercharger to begin. Just my imagination, or is there an issue with the car I should check with the service center? It always starts charging eventually, but I hope I'm not seeing a slow degradation.
