What are the common problems with the Kia Sorento's engine?

I've been experiencing some issues with my Kia Sorento's engine and I'm not sure what the root cause is. The engine seems to be making strange noises and the performance is not as smooth as it used to be. What could be the potential problems and how can I address them?

It's possible that there could be an issue with the spark plugs or the ignition system. I would recommend getting them checked and replaced if needed.

Another common issue with the Sorento's engine is a faulty fuel injector. This could be causing the strange noises and decrease in performance. Have a mechanic take a look at it.

Make sure you are keeping up with regular maintenance and oil changes. Neglecting these can lead to engine problems. Also, check the air filter and replace it if necessary.
