2020 Kia Optima Used. What are the risks?

Hi everyone,

I am looking for a used car and Kia's are among the most eye catching (cheapest) models I keep running across.. primarily the Optima. I see used 2020 models for thousands less than used Camry's, Accords.... even Chevrolet Malibu's. I've test driven a few and they are beautiful inside and out, however I've seen mixed reviews online. Many people rave about how efficient and reliable these cars are... but I've come across many horror stories, mostly about the 2011-2018 model years - about how their engines blow up, their fuel pumps fail and start engine fires and how their transmissions are doomed to fail. Do the 2020 model suffer from this problem? If so, about when can I expect the issues to come up? What are some other very serious issues should I be wary of? I am all ears....
