Typically every electronic component must be rated from -40 to +105 C. I'd imagine there's similar requirements for all the interior parts of a car too. Cars have a lot of glass, so get very hot in direct sunlight and quickly reach ambient on cold nights.

The reason cars take so long to "catch up" to consumer electronics (eg it's only in the last year or two that large LCD displays have started appearing in cars, or that LED headlights have become commonplace) is that the car design cycle is very long - typically about 7 years. Tesla decided to do things differently, which meant they could iterate much quicker. It also meant they used components not qualified for automotive use. Mostly they got away with it, but there have been some issues (for example their large displays started failing in hot countries).

Really hot weather in the Continental USA can be pretty toasty, and if a garage was designed more like a crummy solar furnace, I would expect to see it hit those temperatures.

My car has survived at least 150F interior temperatures parked outside during a sunny Pacific Northwest heatwave. I'm estimating that temp because I had some plastic in the car that was rated to lose stiffness at 150F and it got a bit floppy after the car was parked outside in sunny 105F+ weather weeks on end and the plastic was in shade.

It can be hard on lead acid batteries and shorten their life, some lithium ion battery chemistries top out at 130F ambient operating temperature, and ABS plastic that dashboards can be made of is rated to about 176F. If its 150F ambient, the dash could be even hotter.

Btw, they never actually replaced the camera, just the anti reflection shield, and cleaned the windshield and the camera lens.

I live in Arizona as well and this is why you'll see everyone in parking lots parking under trees in the summer, with empty spaces in between.

Teslas have overheat protection (turns on the AC when interior temp > 105F) for a reason (one of them because it's cheaper to manufacture cars that don't need to withstand higher temperatures).

Tesla’s overheat protection only works for 12 hours at a time. If I were commuting, then maybe this wouldn’t have happened, but during Covid, the car was just sitting there for days without being driven. Tesla doesn’t offer a way to extend overheat protection past 12 hours, even when plugged in.
