None? We simply don't have the kind of reliability data on EVs going out for 10-20 years that we reasonably expect a well-made ICE car to run for (with regular maintenance and without major component failures).

These failures are not theoretical, and have been demonstrated in the wild, and can easily total your vehicle. They might affect you personally if you plan on keeping the vehicle for the long time, or the resale value if you don't.

Inverters are known to degrade and fail, solar inverters basically almost always die somewhere between the 10-20 year mark (and those switch far less wattage and don't operate under conditions as harsh), which imo is not acceptable for a car to get totaled in that amount of time.

Unfortunately EVs are one of those partisan topics on the internet which have a lot of partisan haters and lovers, which makes reliable info on them almost impossible to find.

I personally have both solar at home and drive an EV, so I guess I both into the thing, but I can't say with high confidence that my EV will make it to the 20 year mark with the equal probability a well-made ICE car would.

My point was more that "electric systems" are a well entrenched technology / solved problem. As in, it's not a new method of power delivery. Though, admittedly, I'm not sure how much of that transfers directly into the context of powering a car.

As more time passes I guess we'll know which parts are more likely to fail and they'll be designed around the ability to replace them or design them for robustly, or both.

Fair enough.

I think it's quite positive that this comparison can start to be made, however. Given the relative immaturity of EVs.
