Why does my Kia Niro's engine make a rattling noise?

I have noticed that my Kia Niro's engine makes a rattling noise whenever I start it up or accelerate. What could be causing this and how can I fix it?

I had a similar issue with my Kia Niro and it turned out to be a faulty alternator pulley. It is best to have a professional diagnose and fix the issue to avoid any further complications.

One thing to check is the engine oil level. If it is low, it could be the cause of the rattling noise. Make sure to regularly check and change your engine oil to avoid any potential issues.

It is possible that the rattling noise is caused by a loose heat shield or exhaust bracket. This can easily be fixed by tightening the bolts or replacing the damaged parts.

Another possible cause of the rattling noise could be a problem with the engine's timing chain. It is important to have this checked and repaired by a certified mechanic.

If the rattling noise only occurs when the engine is cold, it could be a sign of a failing oil pump. It is important to address this issue as soon as possible to prevent further damage to the engine.
