I use Level 1 @ home, however I've also used the free Volta Public Charging, which is Level 2, & have had no issues. It sounds to me like an issue with the car. having a higher amperage charger should not cause a problem, because a power source will only deliver what the car will take. As long as the voltage is right, amperage shouldn't make a difference. Now if the voltage is different COULD very well cause a problem. I'd take it back to the Honda Dealer, & have them try to charge it on THEIR level 2 charger. If it doesn't work, & since you've tried different sources, I suspect that it will not, they'll have to admit that it's either a problem with the car, or their charging station also isn't compatible with it, which wouldn't make any sense, since they are a Honda Dealer. Best of luck. If you can get this resolved, you'll see that these really are great cars.
