2018 Kia Sportage — Should You Buy One?
Typical asking price: $13,000–$19,000. There is 1 high-severity known issue you need to know before handing over a check.
Kestrel Take
Handsome, comfortable, and well-equipped, the Sportage is a strong value crossover. The 2.4L GDI (and 2.0T on SX) fall under the Theta II engine recall/extended warranty, so the engine is the key inspection — verify the software and any engine work and listen for knock. A documented, healthy one is a lot of well-built crossover for the money.
