I hope to keep my electric car for at least 10 years
I own a Peugot iOn (rebadged Mitsubishi i-MiEV) manufactured in 2012, so it's 9 years old. I bought it second hand, and the service record shows it's needed zero maintenance (aside from tires). I have not needed to perform any maintenance in the ~2 years I've owned it. I'm not in any way recommending this specific car (although it suits me perfectly); but it shows that even a fairly early electric car like this is 10-year capable. The only downside has been the expected gradual decrease in range.
I've also owned a Tesla Model 3 for 16 months, and it's been maintenance and trouble free. I'm not denying that some people have problems with them, however that's not been my experience, nor the experience of the two other people I know who own one.
I probably plan to keep the Tesla for many years, so hope my trouble-free motoring continues :)
The most trouble-free cars I still go for are used Lexus sedans, especially those driven previously be senior citizens. Not always the coolest but man I never have to worry about anything on it.

That said, you will need to wait like 7 more years until you start seeing 10 year old Model 3s.
