FX37 suspension rust/crack

[Nikosg14]

Hi all.

I own a 2010 FX37S.
While there is no issue with the ride, I have noticed some cracks on parts of the suspension.

Any thoughts?
Could it be dangerous or normal wear and tear? Do I need to replace them?

Thank you
Nik

It is very difficult to tell in the photos. Is the crack just surface corrosion, or does it go deep through the control arm? Can you scrape any of the corrosion away? Try scraping it away and then post a few better pics.
