What causes the Kia Stonic to have a shaky steering wheel?

I noticed that my Kia Stonic's steering wheel tends to shake when driving at high speeds. What could be causing this and how can I fix it?

One possible cause for the shaky steering could be worn out or unbalanced tires. Make sure to get your tires checked and rotated regularly.

Another potential cause could be a misaligned wheel alignment. Make sure to get your alignment checked and fixed if necessary.

It could also be an issue with the suspension or steering components. Have a mechanic take a look to diagnose and repair any necessary parts.
