Wow! Where are you?

I'm sorry you're going through all of these issues.yes you are right. i traded my 2020 for a new one and now i have problems with the heatpump... it is so annoying... today i thought the compressor would explode. it was so loud and vibrating before it shuts off... like an emergency shut-down...
Polestar is pretty much the Volvo EV. Maybe they can do the heating better, but they certainly aren't immune to a new model having serious issues (see recall below for inverter).I'm sorry you're going through all of these issues.
I'm hoping Volvo comes out with some competitive EV options. I've had a bunch of them over the years, and lord knows they should be well engineered for the Northern European climate.

All Polestar 2s Recalled for Problem That Can Shut Down the EV
Basically if you want a reliable EV don't buy a model that haven't been out for a year or two with the same components (the heat pump is new for Model 3).
I can't believe they didn't add some auxiliary heating system to the heat-pump. if it's between a heat-pump and a PTC heater ... i'll pick the PTC heater any day. it *will* get the car warm. Heat-pumps simply do not work well under 25F and stop working altogether when you get into the low 20s or lower. North Texas will hit 5F as a low Monday night so maybe it's a good test for Model 3 heatpump owners...
In the videos that have been posted here and elsewhere it looks like there is a supplemental heating mode. They operate the compressor in an inefficient mode that generates heat directly. This is much like how the motors are used (quote successfully) in an inefficient mode to heat up the battery.
There have been a ton of sensor problems with the 2021 Model 3 that result in cold air blowing out of the vents. I believe @Cybr.Myk in this thread had similar issues and had a sensor replacement. It's possible that there are additional performance limitation with the heat pump, but I think all of the issues that people have found so far have turned out to be software bugs or a sensor failure.if the car doesn't get warm after 15 minutes (like the OP states) ... the inefficient mode isn't good enough.
Maybe Elon should have rung up his friends at Nissan. They've outfitted the Leaf with heat pumps for the last few years. My family member who owns a Leaf doesn't live near the Arctic Circle, but they've never had an issue.There have been a ton of sensor problems with the 2021 Model 3 that result in cold air blowing out of the vents.

I know it's Tesla and their engineering is a bit of a black hole, but I find it hard to believe that total heat output wasn't a top level design requirement for the HVAC system.
It's defective sensors, not that necessarily that the mode isn't good enough. As linked in the EPA document in the other thread, Tesla claims the inefficient mode is as good as a PTC heater if not better.if the car doesn't get warm after 15 minutes (like the OP states) ... the inefficient mode isn't good enough.
When I see the phrase "Tesla claims" in any given sentence - this means Tesla is lying to us.It's defective sensors, not that necessarily that the mode isn't good enough. As linked in the EPA document in the other thread, Tesla claims the inefficient mode is as good as a PTC heater if not better.
Heat Pump Limit?
Jokes aside, what Tesla designed is a lot more complex than the Leaf's and accomplishes a lot more.Maybe Elon should have rung up his friends at Nissan. They've outfitted the Leaf with heat pumps for the last few years. My family member who owns a Leaf doesn't live near the Arctic Circle, but they've never had an issue.
I was told that a few of the engineers working on the heat pump were re-assigned to the fart and video-game team - so maybe there was a brain drain effect.
But absent of defective sensors, there are plenty of people claiming the heat pump system is able to keep them toasty warm even in the cold temperatures described. I have yet to see evidence that the system is unable to keep up.When I see the phrase "Tesla claims" in any given sentence - this means Tesla is lying to us.
Not the first time - and certainly not the last.
