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.
Mercedes built its bestselling SUV on a solid foundation, the 2016-2022 GLC earned genuine loyalty with 100k-mile trouble-free runs and that swanky interior. But the 2025 GLC 350e plug-in hybrid is stranding owners with complete electrical shutdowns while driving, triggering lemon law buybacks in California. Mercedes calls it a software glitch; owners wait weeks for parts from Germany while their $60k SUV sits dead. The standard gas models look promising with refined engines and improved cabins, but thin long-term data means you're betting on Mercedes fixing what broke between generations. Budget for warranty coverage, repair bills hit $5k-6k when things fail, and modern Mercedes complexity makes that a when, not if.
