Why is my Kia Sportage's engine making a strange noise?

I've noticed that my Kia Sportage's engine has started making a strange noise, like a grinding or knocking sound. It's not very loud, but it's definitely noticeable. What could be causing this and how can I fix it?

It's possible that there could be a problem with your engine's pistons or valves. I would recommend taking your Sportage to a certified Kia technician for a thorough inspection and repair.

Another potential cause could be a malfunctioning timing belt. This could lead to serious issues if not addressed promptly, so I would highly recommend getting it checked out as soon as possible.

Have you recently changed your oil? If not, it could be a lack of lubrication causing the noise. Make sure to follow your Kia's recommended oil change schedule to keep your engine running smoothly.
