> Don’t ICE cars require a lot more maintenance per mile than EVs?

Model 3/Y battery replacement is US$15,000 to US$20,000.

Wipes out all other EV maintenance cost advantages.

Modern batteries can last a long while though. If you take care of it and mostly keep it between 25-75% and don't supercharge it too often. There are Teslas with more than 300K miles on the original battery.

I have a model 3 with ~80K kilometers and the battery is as good as new. 2018 model. For someone that drives 10-15K km a year there's maybe 30 years more driving on this battery (400K km).

My previous ICE car had two head gasket replacements in the 10 years I owned it. I also had to replace the entire engine. Oil changes. Brake pads/discs, CV joints... So far the EV is way ahead and based on the current battery degradation should remain ahead.

For used cars, you don’t know what the previous owner did.

EV battery life is more related to calendar age, rather than number of charge cycles and C charging rate.

True, but grey market rebuilt packs for Prius are only $2k to $6k if you know the secret of the Cab fleet companies.

For most other models one is indeed not so lucky =3

How long does the battery last though? Engine replacements are expensive too, but usually every other part breaks before the engine.

Tesla gives 8 years for battery warranty.

Interpret that as you may.

In reality, too early to tell. But probably not 20+ years like a Toyota/Honda engine or even a Mercedes/BMW/Porsche engine.
