Why is my Nissan Juke's engine making a strange noise?

I recently noticed that my Nissan Juke's engine has been making a strange noise. It sounds like a grinding or rattling noise, and it only happens when the engine is running. What could be causing this and should I be concerned?

It sounds like there could be an issue with your engine. It is best to take your Nissan Juke to a certified mechanic to get it checked out.

It could be a problem with your exhaust system. Have a mechanic check for any leaks or damage that could be causing the noise.

Sometimes, a loose or worn out belt can cause strange noises in an engine. Have a mechanic inspect your belts and replace them if necessary.
