I got my 70D on 6/24 and have been enjoying it so far. However, one particular problem is having me concerned: It seems that it has "developed" a hatred for supercharging. After getting my car, I have taken it from LA down to San Diego and back, and also to Carbazon over the last weekend. The first supercharge at San Diego went smoothly without a problem. On the return trip next day, though, it would not charge at San Juan Capistrano, despite changing stalls 3 times. After a call to service and rebooted both screens, it still didn't bulge. Out of frustration, I went to lunch. Upon coming back, I rebooted screens again and it took it this time. And I was happily on my way. Later that night, I got a call back from service and they told me that there was nothing wrong from the logs. And they thought it was a supercharging station problem. I didn't buy that since there had been several other Model Ss charged in that timespan without a problem but I let it go. Fast forward to last weekend, we (me and my wife) did a quick tour of Carbazon outlet. This time, despite more reboots, changing stalls and leave it "cool down" for an hour then try again, it simply doesn't take it. So I called Tesla service again yesterday and ask them to check the logs. No update yet. For all these occasions, the symptom is "Unable to charge. Unplug and try again" after I plugged in the supercharger. I made sure the plug is all the way in. And the car has no problem charging on my NEMA 14-50 home plug. (However, last night it only took 16A instead of 30A out of ordinary and there is an orange ring at the charging port. It may have something to do with it not plugged fully in though. I will try it again tonight.) Any clues on what the problem is? I am pretty sure it is my car and have seen other people having similar problems in the older threads. Seems like the service center replaced some components for them?
