Buy the wrong generation and you're signing up for a warranty engine replacement before 50k miles. The 2017-2023 Kona carries Hyundai's Theta II engine curse, catastrophic bearing failures that one tech saw 960 times in 13 years, plus a dry-clutch DCT that jerks through parking lots like a teenager learning stick. The 2024+ redesign is a different animal entirely: new SmartStream engines with no systematic issues yet, an actual 8-speed automatic, and genuinely competitive packaging for the money. If you're shopping used, generation matters more than mileage. New buyers get a roomy, tech-loaded subcompact that punches above its price point. Used buyers gambling on first-gen models better hope that 100k powertrain warranty outlasts the engine, and that their dealership answers texts during the months-long repair wait.
If you're eyeing a used Soul between 2015 and 2020, understand you're gambling on a ticking clock. Those model years, especially automatics with the 1.6L or 2.0L GDI engines, burn oil like it's their job, thanks to piston rings that fail predictably around 80k miles. Owners report topping off a quart every thousand miles, then one day the engine seizes with no warning light. Kia settled a class action over it and replaced thousands of engines, which tells you everything. The first-gen Souls (2010-2013) ran to 200k+ without drama, and the 2023+ models seem cleaner, but there's not enough road time to confirm the fix. What the Soul does well, maximum cargo in a tiny footprint, quirky looks, easy city parking, it does better than almost anything this size. Just make sure the one you're buying isn't someone else's oil-burning problem waiting to become yours.
