Why is the Ford Mondeo making a strange noise while driving?

I recently purchased a used Ford Mondeo and noticed that it makes a strange noise while driving at high speeds. What could be causing this and how can I fix it?

It could be a problem with the exhaust system. I suggest getting it checked by a mechanic.

Check the tires for any uneven wear. It could be a sign of misalignment which can cause strange noises.

I had a similar issue with my Ford Mondeo and it turned out to be a loose belt in the engine. Take it to a trusted mechanic for inspection.
