The Fusion splits cleanly into winners and losers depending on what's under the hood. The naturally aspirated 2.5L is a quarter-million-mile workhorse that owners genuinely love, and the hybrid drivetrain with its Aisin eCVT is equally bulletproof while delivering 40+ MPG in the city. But the 1.5L and 2.0L EcoBoost engines from 2013 through most of 2019 have a coolant intrusion defect that kills engines between 60k and 100k miles, not a rumor, a documented pattern across dozens of independent owners. Ford fixed it late in 2019, but those earlier turbo models are landmines unless the engine's already been replaced. If you're shopping used, check the engine code before you check the CarFax. Buy the 2.5L or hybrid and you'll understand why some owners hit 250k miles and post about it. Buy a pre-2020 turbo and you're gambling with a motor that has a known expiration date.
This is what happens when aerospace engineers build a luxury sedan: world-class hardware wrapped in frustratingly unfinished software. The powertrain delivers 512 miles of real-world range and S-Class ride quality, with used Grand Tourings hitting $55-65k (down from $125k new) that make German rivals look overpriced. But the mobile key fails often enough that you'll keep a backup card in your wallet, the infotainment freezes mid-drive, and Dream Drive Pro throws phantom brake warnings on clear roads. Owners who've logged 26,000+ miles still call it irreplaceable, if you can tolerate rebooting after every charge and live near a service center. The company's financial crisis (losing $330k per car in Q1 2026, production guidance suspended) makes this a gamble on whether Saudi backing keeps them afloat long enough to fix the software. Buy it if you want the best EV powertrain money can buy and have patience for startup quirks. Skip it if you expect Tesla-level polish or need a car that just works every time you walk up to it.
