Why is my Kia Rio making a strange buzzing sound?

I recently bought a used Kia Rio and it has been making a strange buzzing sound whenever I accelerate. What could be causing this and how can I fix it?

This could be due to a loose or damaged exhaust system. It is important to get it checked and fixed by a professional mechanic.

It could also be caused by worn out engine mounts. Have them inspected and replaced if necessary to prevent further damage.

Check your vehicle's air intake system for any clogs or debris. Clearing it out could help resolve the issue.

Another possible cause could be a faulty transmission. It's best to take it to a trusted mechanic for a proper diagnosis and repair.
