Known faults

Reported by owners, mechanics and buying guides for this model and age. Check which engine the car has, as some apply to one engine only.

  • Timing belt that runs in oil (1.0 EcoBoost)
    1.0 EcoBoost petrol

    The 1.0 EcoBoost’s timing belt sits in the engine oil. Missed or wrong-spec oil changes can make it break down and block the oil pickup, which can wreck the engine.

    At the viewing: Ask for a full service history with regular oil changes, and whether the timing belt has been changed when due.

    If it needs doing: Timing belt (cambelt) change, about £300–£700 (often with the water pump). ClickMechanic
