Yes, when the main electronic of a Model 3 fails, the car is broken, until the failure is fixed. On the first glance, it is somewhat a concern. But then, it is not so that more conventional cars are much more useful if some important electronic component fails either.

Most of the components that can fail beyond electronics in a "normal" car, the Tesla just doesn't have.
