The Munro guys have talked about how rapidly Tesla quality has advanced— going from amateur on early model s to impressive of later model 3s. I wonder how much of this is that early amateur hour stuff? I take the Munro guys opinion pretty seriously.

Munro praised the heat pump design in newer Model 3/Ys which are now failing at pretty high rates in dangerously cold conditions. I don't doubt that the design is very clever and efficient, but I wouldn't take Munro's approval as an indication of how reliable a design will be into the future and in extreme (i.e. non-Californian) conditions.

Fixed with an OTA update though https://electrek.co/2022/01/17/tesla-software-fix-heat-pump-...

[enragedcacti]

They failed to fix it with the first OTA update. As far as I'm aware we don't really know if the second OTA has fixed it entirely, if its just switching to the "motor slip" mode of heating sooner, or if we will see more failures in the future.

Either way I think the point stands that Munro's analysis didn't catch this possible failure mode.

Are you at least going to acknowledge the fact that Tesla can, in span of a few days, and then few days after, push multiple fixes to its entire fleet of vehicles whereas any other manufacturer would have had to physically get those cars in, pay for labor, hire cars, etc.

Are you aware of how often other cars of any brand/class are recalled for issues that Tesla simply pushes OTA to fix? Issues that never makes the news (dozens per week of them) while the OTA does? If you don't know, I suggest you look into it.

[enragedcacti]

The first OTA was last winter, not a couple days before the next OTA. I am glad that Tesla has started to drag everyone else forward with software updates but I think the heat pump issue is still a valuable data point for evaluating Tesla's engineering prowess and methodology. You can't hotfix every mechanical issue and I think you could argue that Tesla's methodology can lead to more rapid improvements but more unexpected problems than the more cautious approach of other manufacturers.

Due to how long they’ve been making the S now I’d say it’s more likely to be a couple of specific manufacturing issues, like the wishbones and dipped beams mentioned.

I don't take this guy too serious. He seem to know little about what has been happening in car engineering for the last 30 years, and I am not a car engineer, having to say that.

That company literally worked on many major car projects for those 30 years. What do you think have they been doing? They were involved in the RAM truck overall that made it really popular for example.

Their costumers are literally car companies who want to know if competitors are using new technologies that they might be able to use.

If you want to see an example of what the produce, check out this report that they sold for 10$ (usually these cost many 100k$). This is a 23,793 pages report on every details and new technology in the i3.

He also fell for Plasma Kinetics grift which seems to run into some basic physics problems https://youtube.com/watch?v=-8NQkOeRNpg so I am not sure in how far Munro can be trusted on things which are not fasteners.
