My car overheated while supercharging last week. It was a long charge (approx 1.5 hours) at high altitude (7,000 ft). The result was I got an error message that said battery cooling and A/C were affected and to contact Tesla service. The A/C did not work again in the car until it had been parked overnight. This has never happened before so I wonder if the issue is that the car cools the battery less effectively at higher altitudes due to the thin air? It was about 90f outside while I was charging.
