No chronic failure modes. Main checks: 2.0T oil consumption, 2.7T boost system health, and SYNC4 infotainment responsiveness.

What the VIN tells you
The Nautilus has a real engine fork and the 8th VIN digit settles it. ‘9’ = the 2.0L EcoBoost turbo four (250 hp), the standard engine (confirmed on OEM used-engine listings, e.g. Turbo Auto Parts ‘2.0L VIN 9 8th digit turbo’). The up-level 2.7L EcoBoost V6 (335 hp — the twin-turbo ‘Nano’ shared with the Edge ST) carries a different engine character, so a ‘9’ in the 8th position confirms you are looking at the four, not the V6 a seller may be advertising. The two have different inspection priorities: the 2.0L EcoBoost four is worth an oil-consumption check on higher-mileage cars, while the 2.7T’s watch items are boost-system health and cam-drive/timing history. Note the 2.0T here is a Ford EcoBoost — not GM’s LTG — so cross-brand ‘LTG’ oil-consumption comparisons do not apply.
