I'd guess they fail not on their own, but because they are human interface devices and take the brunt of abuse... e.g. iPhone screens are a popular repair despite being reliable components.

I have a 2023 model 3 and my screen had a small defect develop, a slightly darker area in a roughly half cm diameter area. I think most people would have never noticed but I pointed it out to Tesla service and they replaced the screen.

Some newer models have better (bigger) screens, and some are incompatible since they've slightly changed the connector. Old models (pre highland/ jupiter facelift) have used the same display shown in the article for a very long time across M3 and MY. What usually happens is that they physically break because people are not that careful, so the touch screen ends up breaking - although you really have to put a lot of force to break that display.

My 2016 Model S LCD panel developed the well-known fault of delamination and leaking some kind of sticky fluid.

Turns out the early Model S vehicles used consumer grade LCD panels that weren’t designed for the prolonged high heat you get in a metal and glass box left outside in the sun all day.

Tesla since upgraded their vehicle screens to proper automotive-grade LCDs which are excellent.

My point is, automotive-grade hardware is higher spec than regular consumer computer hardware, hence the high prices.

As an aside, I upgraded my whole computer and screen from MCU1 to MCU2 and it was worth the upgrade.

Credit to Tesla for building a retrofit computer upgrade for old vehicles. Thats a non-trivial thing to engineer and I appreciate their effort. Other car manufacturers would prefer you were compelled to buy their latest vehicle instead.
