If your engineering team had to wait for a product failure to realize an item that's going to be outdoors in the sun is going to get hot, what on earth else are they missing?
They put a non-automotive grade LCD in Teslas. I assume because they thought they knew better. I suspect hubris is at play more than full-on incompetence.

As a Canadian, 32F seems like an oddly high lower limit to me. Things should operate down to at least -40.
Assuming you can keep something in the shade - does anywhere on Earth get to 140F beside inside forest fires, lightning bolts and volcanoes? There is a substantial portion of the worlds population that lives months at a time where temperatures are regularly well below freezing.
It should work at an extension of military temperature ranges for global use indoors, outdoors, and in odd semi-indoor scenarios like the back of a hot truck: -75 to +125 C / -103 F to 257 F. Treating it as retail consumer electronics shit isn't rugged enough for real use.
Speaking of which, how could mobile phones be made to work in extremely hot temperatures for emergencies without shutting down?
However, since most phones are relative water resistant now, a good option is to use evaporative effects to cool them down. You could also dig a hole in the earth to find cooler temps and dissipate heat that way.
Starlink is in beta. The entire purpose of the beta is to find stuff like this. They found something, and I'm sure that the next iteration of this before it goes to mass market will account for it. You're just seeing the system work.
This flaw was known to SpaceX before the beta began; SpaceX has publicly said the dishes are only certified to 104° Fahrenheit. Musk prefers to ship known broken products in the name of velocity, and out of a sociopathic contempt for the consumer. It’s happened to me more than once.

Just curious, what are the differences between normal LCD's and automotive-grade LCD's?

You can find same chips (=same function) made for consumer electronics, automative, aeronautic and military, all with different temperature and humidity ranges. I'm not sure about mobile phone CPUs/SoCs, but automotive equipment is a lot more resilient to voltage spikes well above the normal 12-14V.

The link is mostly a honeypot for Elon Musk haters. I wonder if they have bothered looking at the operating temperatures of other satellite Internet dishes? A simple search will net you heating and cooling devices for satellite dishes. If you face more extreme temperatures, you need only go buy a heating and cooling unit. http://www.dishcamo.com/dish_heater.htm
You can't have a lot of positive attention without a corresponding amount of negative attention when something goes wrong.

> No, failing at 122F is not acceptable I don't think it is a simple as saying that. If, for example, it cost twice as much to design something that works up to 140 as it does to make it work up to 122, I don't think it makes sense to make everyone in the world pay twice as much for something they don't need. You should sell a more expensive version that works up to 140.
There's a cost to building multiple SKUs. Also you massively overestimate the cost of materials for withstanding such temperatures.
I think it is a design decision, and the costs and benefits have to be weighed. If the extra cost per unit is more than the lost revenue from not being able to sell to consumers in hight temperature locations, it might make sense not to design it for high temperatures.
As long as these limitations are communicated to potential customers, I don’t see a problem with that.
I’m always surprised how poor engineering gets exposed in products I purchase being an Arizona resident. No, failing at 122F is not acceptable. If your hardware is exposed to outside conditions, it should operate easily below 32F, and well above 140F. Considering that phones can operate below 0F and near 122F, that’s embarrassingly bad. Same thing in vehicles. If you’re driving consistently at interstate speeds, you…
122F is not a normal temperature.
