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. If oil changes are missed or the wrong oil is used, the belt can break down and shed bits that 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 Ford says it’s due.

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

  • PowerShift automatic gearbox
    Automatic versions only

    Automatic Fiestas with the PowerShift gearbox can give jerky changes, hesitate, or in bad cases lose drive. Repairs can be expensive.

    At the viewing: If it’s an automatic, pull away gently from a standstill several times and drive in slow traffic. Any judder, clunk or hesitation is a warning sign.
