    All the Ecoboost have issues. But yeah, that 3 cylinder is specifically terrible.

    2.0 Ecoboost as fitted to my Focus ST here. Oil changed every 5000 klms with fully synthetic SP grade oil, being GDI turbo I don't lug the engine in 6th from ~2200 RPM onwards when accelerating on the freeway (I always change down to fifth in the instance I'm really loading up the engine). Just ticked over 125,000 klms without a single issue. Granted the 3 cylinder engine is problematic with it's wet timing belt, but I've had no problem with the 2.0 EcoBoost.

    i hear its transmissions, even the manuals, are sealed and don't allow for regular fluid changes. that's atop of the cylinder head wet belt or whatever issues these are known for.

    talk about planned obsolescence right there.

    Nah, fluid changes are no biggie, but for wet timing belt replacement you have to take half the engine apart. If you don't, the engine might seize up doing 90 on the freeway giving you a generous 5 seconds to react after the oil pressure light comes on.
