What are the most common issues with the Kia Soul engine?

I have a Kia Soul and I've been experiencing some problems with the engine. What are the most common issues that I should be aware of?

One of the most common issues with the Kia Soul engine is a faulty air filter, which can cause a decrease in performance and fuel efficiency.

Another common issue is a malfunctioning ignition coil, which can lead to engine misfires and rough idling.

It's also important to regularly check and replace the engine oil, as dirty oil can cause damage to the engine.
