Given that the refreshed Model X is supposed to be using a heat pump, I'm looking to see if anyone who has received their X are noticing any issues with heat in cold climates? I'm asking after the issues with the Model Y/3 over heat pump failures and seeming lack of heat in the cabin. I'm finding that my wife's Model Y can warm up fine, but that once under way, the warmth in the cabin drops noticably - much more so than my Model S. I'm also wondering if the system in the X is as loud as the Y's.
