Why is my Ford S-Max making a weird noise?

I recently bought a Ford S-Max and it's making a strange noise whenever I accelerate. It's similar to a high-pitched whining sound, but it's not consistent. Any ideas on what could be causing it?

It could be a problem with the transmission or the exhaust system. I would recommend taking it to a mechanic to get it checked out.

Check your belts and pulleys, it's possible that one of them is loose or damaged. If that's not the issue, it might be a problem with the spark plugs.

I had the same issue with my Ford S-Max. Turned out to be a faulty power steering pump. Make sure to get it fixed as soon as possible to avoid any further damage.
