Why is my Ford Mondeo making a rattling noise while driving?

I recently purchased a 2016 Ford Mondeo and I've noticed a constant rattling noise coming from the engine while driving. It seems to get worse at higher speeds. What could be causing this and is it something I should be concerned about?

Hi Alexandra, it's possible that the rattling noise could be caused by a loose heat shield or exhaust system. It's best to have a mechanic take a look at it to determine the exact cause of the noise. In the meantime, try to drive at lower speeds to see if the noise lessens.

I had the same issue with my Ford Mondeo and it turned out to be a faulty belt tensioner. It's a relatively easy fix, but definitely something you want to get checked out sooner rather than later to avoid any potential damage to the engine.
