Why is my Ford S-Max making a strange rattling noise?

I recently purchased a used Ford S-Max and have noticed a strange rattling noise coming from the engine. It seems to happen when I am accelerating or going over bumps. Can anyone provide insight into what may be causing this and if it is something I need to be concerned about?

It sounds like you may have an issue with your exhaust system. I would recommend taking your car to a mechanic to get it checked out as it could potentially be a serious problem.

I had a similar issue with my Ford S-Max and it turned out to be a loose heat shield. I would suggest checking for any loose or damaged parts in the exhaust system.

I had a similar issue and found out that it was caused by a loose strut mount. I would recommend having a mechanic inspect the suspension components to see if that is the culprit.
