Tesla Motors Club

I am a new Tesla Model S owner. It's a 2015 70d. This weekend I tried to keep climate control on while charging the car, and I got a message on the dash screen that said "Air Conditioning Reduced DC Fast Charging/Supercharging may be reduced". I ultimately unplugged the car, got out of the car, got it to completely turn off, then the message went away and the climate control began working properly.

Today my wife is driving the car and now the same message came up on the dash, but it's now accompanied by a message on the touchscreen that says the same thing. She is not charging the car obviously if she is driving it.

Has anyone had this issue? Is this indicative of something larger wrong with the AC, or just a glitch in the system?

Thanks
