Maybe, but 2021.44.30.2 is being installed only on Model 3, S and X so far according to TeslaFi.Edit: I just saw 2021.44.30.2 rolling out, is this maybe the fix?

A mobile tech just visited to make sure our Model Y had no hardware issues causing our heating problem. Diagnostics showed everything was ok. He believed things would be fixed by firmware only and that the current firmware is expecting sensor tolerances that are too tight. My speculation: they have changed some of the sensors and they are responding differently in cold temperatures.Maybe, but 2021.44.30.2 is being installed only on Model 3, S and X so far according to TeslaFi.
Sharing this from the canada forum, it seems we should check our front grille flap when this happens?

I don't know whether it is a design flaw or not, but I must agree. It can't just be the flap.So, the "grill flap" excuse that seems to be going around, can someone explain why a car that's washed daily to get rid of snow/slush build up still get the fault and if it's a "grill flap" issue, then why does the fault go away after a restart of the car (because that's the only way I can resolve the multiple heat failures I've had and it also takes at least 10min+ for heat pump to finally work again after the restart)?
I find that it's much more than just the "grill flap", and there is a heat pump design flaw (...)
Maybe the comments by ke6gwf - Ben Blackburn will help a bit.

Has this dude ever driven in the snow? You'd have to stop every few miles to keep it "clean" from snow when there is snow on the road...I don't think thats the one, not fast enough I would say. Let's wait and see. Also Elon acknowledged the issue replying the tweet:

I asked what the error code was in the Canada forum, so this answers that. I doubt the problem has anything to do with louvres at that temperature. Service time!I applied 2021.44.30.6 and I still have the same issue (VCfront_a447, no heat). I wanted to add that I've noticed strange behaviour from the front louver as well - they never seem to close anymore. Possibly coinciding with some ice buildup earlier this week. Maybe they got damaged in the process? They do seem to articulate, they just seem to revert back to the open position. I haven't tried rebooting the car since the software update was applied though. It's only -4ºC here now. Cmon Tesla....
Yes, it seems so. I got another reply from the service centre just now and they seem slightly more certain this requires replacement of the compressor and/or supermanifold.I asked what the error code was in the Canada forum, so this answers that.

Totally agree. I am ecstatic that this is getting this level of attention.Many thanks to those Canadian members who notified Transport Canada. That seems to have been the tipping point to get this issue some real visibility. Apparently TC and NHTSA talk to each other, and Tesla is now dealing with NHTSA as well (discussions, no recall at this point).
That got it on all the general EV and Tesla fan sites, so now it's really out in plain sight. The only problem is that the public now thinks this is a very new issue, when in fact failures started happening the first time it got cold after the heat pumps were first released LAST winter.
So it's taking a full year to get some action, but it's finally happening. Can't thank you guys enough. If Tesla can get a fix together quickly enough to show THIS WINTER that the problem is well and truly solved, a Y will be back in contention as my next EV.
Hopefully with the pressure from NHTSA and Transport Canada there will be some action here. Part of the reason Transport Canada is ticked off is because when a manufacturer learns about a safety issue they are supposed to contact Transport Canada as well as the impacted owners immediately. We all know how well Tesla communicates as in they pretty much never communicate at all.Many thanks to those Canadian members who notified Transport Canada.

Not the case here. I think the owners who found themselves hours from anywhere in -30°C temps with their family in the car would have appreciated a heads up before heading out onto the highway.It is hard to notify impacted owners until you have determined the root cause.
I don't know about Transport Canada, but here in the US you normally don't notify anyone, NHTSA or the owner, until you have completed your investigation, determined the root cause, and identified what vehicles are likely impacted. (Unless a significant amount of time has passed and you still can't identify the issue, then you notify NHTSA, but normally not the owners at that point.)
It appears that the root cause, or causes, haven't been identified yet. (And there are very likely multiple different issues presenting with similar symptoms.)
Who's hours from anywhere in an EV in -30 c temps?Not the case here. I think the owners who found themselves hours from anywhere in -30°C temps with their family in the car would have appreciated a heads up before heading out onto the highway.
Lots of people? -30°C isn't exactly abnormal for some places.Who's hours from anywhere in an EV in -30 c temps?
