FYI: information regarding the heat pump issues some are facing in extreme cold. From Saskatchewan Tesla Owners club: @elonmusk
Just got some really encouraging news, and context re. Climate system from our amazing tech at Tesla Saskatoon, as we dropped off our 2022 Model 3 this AM. I wanted to share to help others:
Tesla is taking this cold weather climate problem very seriously - they’re very worried about the safety of drivers and have definitely prioritized this issue. The tech is on a group chat with engineers in
Fremont and Alaska, and has been working directly with them over the past few weeks to figure this out. They’re all working together, and when necessary some parts from cars, including Mark Kroeker’s, are being overnight shipped to California for them to figure out what going on.
I also am encouraged to hear why a software update is going to make a really big impact immediately for all Y/3 owners (and the update is in progress now, ETA unknown but asap):
1) The heat pump system actually has the ability to work really well, even in temps colder than -30C, because there are two loops that use compression and expansion of the refrigerant (going from liquid to gas to liquid) and those loops can produce heat, even in the extreme cold.
