Why is my Ford Mondeo shuddering and shaking while driving?

I recently purchased a used Ford Mondeo and I've noticed that it shakes and shudders while driving at high speeds. What could be causing this issue?

It's possible that your tires are out of balance or your alignment is off. Have a mechanic check these out.

Another possible issue could be a faulty transmission. Take it to a certified mechanic for a diagnosis.

If your Mondeo has been sitting for a while, the fuel injectors may need to be cleaned. Try using a fuel injector cleaner or have it done professionally.
