Why is my Nissan Qashqai's engine making a loud noise?

My Nissan Qashqai has been making a loud noise from the engine since last week. I'm worried it might be something serious. What could be causing this and how can I fix it?

It could be due to worn out engine bearings. This is a common issue in older Nissan Qashqai models. It is important to get it checked and replaced as soon as possible to avoid any further damage.

Have you checked the oil level? Low oil can cause the engine to make strange noises. Make sure to top up the oil if it is low.
