Why is my Kia Rio's engine making loud noises?

I recently noticed that my Kia Rio's engine has been making loud noises, especially when I accelerate. What could be causing this issue and how can I fix it?

If you hear a knocking noise, it could indicate an issue with the engine's bearings. It is best to bring your Kia Rio to a trusted mechanic for a proper diagnosis and repair.

One possible cause of loud engine noises could be worn out spark plugs. It is important to regularly check and replace spark plugs as needed to ensure proper engine performance.

Another potential cause could be a damaged exhaust system. It is important to get your exhaust system inspected and repaired if necessary to prevent any further damage to your engine.
