What are the most common problems with Kias' engines?

I've had my 2015 Kia Sorento for over 100k miles and I'm starting to notice some engine issues. Specifically, my oil consumption has increased significantly over the past few thousand miles. I've checked the valve cover gasket and it's fine, so I'm not sure what's causing it. Has anyone else experienced this problem with their Kia?

I've owned two Kias and had issues with engine stalling on my Sorento, while my friend's Optima had a faulty timing chain. Research suggests that Kia's V6 engines are prone to oil leaks and excessive oil consumption, likely due to design or manufacturing flaws.
