Recent heat pump failures - software issue?

[CyclingBen]

Just adding an update to my data point. Certainly everyone's case is probably different and likely some hardware vs software issues. My vehicle is currently fixed on the 44.30.7 update (at least -5F/-20C today driving today). I sure hope I don't jinx it by posting this. 2022 Model Y that had the a447 error 4 times while on the 44.30 software.

I hope you all get yours fixed soon.

Ah, it was -18C this morning and its the first time i've felt my steering wheel vibrate, was a little suprised but figured it was the heat pump after turning down my music volume.

Either way, even at this temp I think the heat pump was pretty efficient.
I had a 50 km drive at speeds of 110-130 km/h and still managed 170 wh/km(270 wh/mile)

Both great things to hear!

So do I dare to drive to Collingwood tomorrow, or do I condemn myself to my wife's 2010 minivan? I'm on 30.7.

Based on your signature (Aug 2021 delivery) I'd say your heatpump/supermanifold will likely be fine. I've seen a few people with hardware faults in 2021, but it doesn't seem to be widespread. You have the latest firmware.

If it was me - it would not stop me. I'd want to find out ASAP if I have a problem so I can get it resolved. I wouldn't want to own a car where I was continuously wondering if was going to fail.

What do you mean by Vibrate? Does the steering wheel vibrate when it is cold out or all the time?
In all my years driving, never had a wheel vibrate unless there was a front end problem.

I will tell my wife these encouraging words if it goes off the rails. "Better to know, honey, than to be unaware!"

Also - bring some blankets. Mine failed on a 14 hour roadtrip from Ottawa to New Brunswick and we had 3 hours of no heat at -14C outside. We had two blankets in the back (and I ended up buying two more at a truck stop). Since the issue happened I haven't had the problem again, but now I keep the blankets in the deep trunk of the MY....

At those temps it was uncomfortable in the car, but not dangerously so. I configured the HVAC to blow at the windshield with a medium setting on the fan and that was able to keep it defogged. If it had been snowing or freezing rain then it would have been a major problem to keep the windshield clear.

We timed our return trip based on the weather, but luckily we didn't have any issues on the return trip with either the weather or the heat.

I had like a 5 min stopover and when I got back in the car the heater kicked back in on high. I could feel the steering wheel lightly vibrating. I stopped noticing it maybe 30 secs later once I was back on the road.
I almost always preheat the car before I get in so I've probably never experienced the heat pump working hard.

My parts weren't in either so I pushed the SC visit until Feb 1.

You might be right.

I just drove from Guelph to Craigeith. -24C at the start, consistent to about -21c until coming downhill to a balmy -12C.

The heat stayed fine the whole time. I preconditioned for about 30 minutes before departing in a garage. A good sign!

(I won't talk about battery efficiency though LOL!)

Car back from service centre. Replaced supermanifold and compressor and a selection of other parts. Heating working fine now, asked whether the replacement parts were redesigned but given response along the lines of that they are to an extent which doesn’t give much confidence that this won’t happen again.

I am a fellow Winnipeger 2021 m3 with 44.30 update and yesterday -25c no heat. Got appointment for jan. 21 ugh Tesla has paid to rent me a gas car. This has been a problem since heat pump came out not acceptable imo.And also a safety issue in this part of the world.

Tesla called today they are changing the supermaifold when parts arrive. ugh

 

[Justus]

Can you ask if it's a redesign or a stock replacement? Any idea of what the failure of the part is?

Tesla told me today they're putting in a supermanifold in my car which is a revised part.

If they had to change a part, that suggests that there's going to be a huge recall.

I'm getting an update to 2021.44.30.8 now. Release notes say it might help deal with heat issue.

I don't think the official Tesla notes say anything about the heat issue, but there is speculation that it is an undocumented fix.

 

[thinger]

Elon said that fix coming but newer told in which version. I still don’t believe that SW can solve this.

Don’t know but my early 2021 model y which SC told they won’t be changing any parts until it’s reproduced with the .7 software is parked in the garage and the front flap is fully open… don’t know if that’s any normal.
