A capable, feature-rich family hauler crippled by one huge asterisk: if it has the 2.4L or 3.3L Theta II engine, you're gambling on engine failure.
Every documented failure, earliest first
Ordered by the mileage the problem typically appears. VERY HIGH
confidence means it's tied to a documented NHTSA recall, and 1 of these are rated Critical.

Panoramic sunroof / side curtain airbag bracket detachment (recall) and MDPS steering column cowl crossbar bolt (recall)
How to catch it: Run the VIN on NHTSA.gov before purchase to confirm both recalls were actually performed, not just mailed.

Theta II 2.4L/3.3L engine excessive oil consumption, rod bearing knock, potential catastrophic failure (subject of multiple Kia lawsuits/settlements)
How to catch it: Check oil level monthly with a dipstick, keep every oil change receipt, and check Kia's Theta II lifetime engine warranty/class action settlement eligibility (America's Kia Engine Litigation) before buying — this can get you a free short block.
