Remote issue diagnosis is definitely the way of the future. After noticing my HPWC only is able to charge at 40A instead of the usual 80A, I called the support line, which promptly diagnosed my issue as a failure of one of the on-board chargers. They notified my closest Service Center who will hopefully come out with a loaner soon. In the meantime I am reduced to slow charging at home... No big deal... My level of frustration, however, is at an all-time low in comparison with an issue with my ICE SUV that I would have had to take the dealership to get diagnosed and serviced. Tesla: 1, ICE: 0.
