I wonder why power unit components always fail in race only. Why could they not in FPs or quali, too? It would be more realistic, I guess.
Also, it might be good to have an opportunity to recover failed component, like an extra R&D task, paid by resource points. I am not saying to recover it fully but perhaps some percentage of it so it could still be used as PU component for FPs. Of course, I don't expect it to succeed every time, let say 50% chance to recover 20% from component.
And that could also be available to apply to used components 😉
