Why does my Ford Fiesta shake at high speeds?

I recently bought a used Ford Fiesta and noticed that it shakes at high speeds on the highway. What could be causing this issue and how can I fix it?

This shaking could be caused by misaligned wheels. It's important to get them realigned by a mechanic to prevent further damage to your car.

You may also want to check your tires and make sure they are properly inflated. Low tire pressure can also cause shaking at high speeds.

Check to see if your suspension components, such as shocks and struts, are worn out and in need of replacement. These can also cause shaking at high speeds.
