They can’t have perfect quality control for every part that leaves the manufacturer, especially considering the massive temperature fluctuations they might experience, humidity changes, road salt, and the fact its attached to something hitting bumps and potholes at 100+ km/h.
Well every car has wheel bearings that experience all those same conditions and last hundreds of thousands of miles. Brake calipers can also stop functioning, rubber lines can plug up, people can never change their pads and rotors.
I’ve had a wheel bearing last 20k miles. It depends on the abuse. My ultimate point was that an electronic motor still has several possible failure points.
Idk it might use magnetic brake pads. I have used them in other fields & they are pretty nifty. The ones I used created eddy currents & had not mechanical wear. For my project the mechanical brake had a ~10 year lifespan while the magnetic brake could last ~50 years. Also the mag brake was only 30% more expensive but didn’t need maintenance & would be significantly cheaper if you took the lifespan of the project.
Welcome to the world of mostly solid state systems. Turns out when friction is a solved problem there’s no need for cottage industries like brake pad and rotor production.

Unless they deliberately put in a part designed to wear out in 5 years, there’s really nothing in an electric motor that would.
Bearings can sieze up, starting capacitors can go. A worn bearing can overheat the windings and cause damage.
Yes, but those are things that can be designed to last decades, at very little cost.

So… how do manufacturers of hydraulic brakes do this?? Or any other safety- critical part on a car?
They don’t. Parts like calipers failing and rotors warping is common.
