Why is my Kia Niro's engine making strange noises?

I recently purchased a Kia Niro and have noticed that the engine makes strange noises when I accelerate or decelerate. What could be causing this and should I be concerned?

It's possible that there is a problem with your engine's bearings. I would recommend taking your Kia Niro to a trusted mechanic for a diagnostic test.

Another potential cause could be a faulty spark plug. I would suggest having your spark plugs checked and replaced if necessary.

In some cases, strange engine noises can be caused by a loose or worn out belt. I would recommend having your car's belts inspected and replaced if needed.
