    That is tuned mass damper. There are two on that same part. The one that’s broken off and the one that’s square block to the side. There are also others in Prius like the one on left (passenger) side engine mount. Those are designed to stop resonances from happening or to quiet resonances down.

    I would just leave it off. And don’t worry about it.

    Because as car ages rubber in those pars deteriorates and changes the frequency where it’s tuned which makes those parts less useful. Also older cars tend to have some resonances and noises anyways. And Prius doesn’t have any resonance related problems (that could be link to this part) so these aren’t needed because of structural integrity.
