Hello all,
New forum member here (and newer Tesla owner). I picked up a Model 3 Performance in late June and just took my first long trip in the car yesterday. First time supercharging went well. I went from 14% SOC to about 50% with no issues.
When I arrived home I used my wall charger (that I have been using for about a month now, 60A circuit, and configured as such) for a quick top up and went to the grocery store. When I arrived home for the evening I plugged the car back in, and within a matter of 30 seconds or so it was charging at the normal 48A. It said it would be finished charging in about 3 hours.
After about 3 hours I noticed I didn't get the charging finished notification. I looked at the app and it was only charging at 24A. In the garage I saw the three flashing red lights that I looked up meant overheating. I unplugged the charger, turned off the breaker to it, let it "cool off" for about an hour, and plugged it back in. The charger would try to ramp up to full amperage. It would get to about 17A and then go back to 0A and repeat this process over and over (Voltage hovered around 240v - 238v during this time). I then took out my mobile charger and plugged it into where my dryer is plugged in (have used it in the past just fine). It was doing the same exact behavior. I then resorted to trickle charging the car off of 120v without issue for about an hour.
I then decided to go drive the car a mile a way where a free destination charger is. It was able to charge at 40A without issue. What!?! So then I drove it back home, plugged in my wall charger, and it worked fine as well up to 48A and topped off the car in about an hour.
I have a service appointment scheduled for next Monday. But I'm at a loss as to what happened.
