It does not need any maintenance like gas cars do. It only needs re-charging and occasional replacement parts.

These were the only repairs:
1) Something went wrong with a sensor in the rear seatbelt and it needed to be replaced.
2) Two power windows buttons broke and needed to be replaced.
3) I had two flat tires.

I replaced worn out tires a few times. EV's are heavy, so they put more stress on the tires.

The shock absorbers are worn out, but I did not replace them yet.

Even the brakes last longer. It uses regenerative braking most of the time. That means the motor turns into a generator for braking. The motor slows the car down and recharges the battery a little bit during gentle braking. I only use the regular brakes for hard braking.

The battery is the most expensive part. The battery still has about 90% of the original range. I expect the battery to last about 300,000 - 400,000 miles. When the battery wears out I may need to get a new car.
