High-performance electric motors do fail all the time. They overheat, position sensors are slipping, the converters IGBT's last max 6 years.

You are talking simple engines, I'm talking high-end engines.

In the context of the motor alone, those don't fail.

The circuits driving it probably have a higher failure rate, but we've gotten so good at manufacturing electrical circuits it still seems much easier and cheaper than a mechanical engine.

I worked with high performance electrical engines. They do fail all the time. Not in cheap consumer cars though.
