Why is my Ford S-Max making a rattling noise when I accelerate?

I have a Ford S-Max and recently whenever I accelerate, there is a loud rattling noise coming from the engine. It seems to be getting worse, what could be causing this issue and how should I address it?

It sounds like you may have an issue with your exhaust system. The rattling noise could be caused by a loose or damaged exhaust component. I would suggest taking your car to a certified mechanic for a thorough inspection.

Another possibility could be a problem with your car's fuel system. If one of the fuel injectors is malfunctioning, it could create a loud rattling noise. I would recommend taking your car to a Ford dealership for an expert diagnosis.

I had a similar issue with my Ford S-Max and it turned out to be a problem with the timing belt. It is important to get this checked and replaced if necessary, as a damaged timing belt can cause serious damage to your engine. Take your car to a trusted mechanic as soon as possible.
