Reliability
4.0/5

3 known faults

1.0 EcoBoost 100

  1. Wet belt of the 1.0 EcoBoost

    Severity 3/3 · Serious

    On the 1.0 EcoBoost, a belt (timing or oil pump belt depending on the version) runs in the engine oil. As it degrades, it releases debris that clogs the oil pump pickup: the engine is no longer lubricated and can seize. Ford disputes that the fault is widespread and asks owners to follow the servicing schedule strictly. Focus IV reliability guides advise requiring service invoices and monitoring the oil level.

    Versions
    1.0 EcoBoost 100, 1.0 EcoBoost 125, 1.0 EcoBoost 125 BVA8, 1.0 EcoBoost mHEV 125, 1.0 EcoBoost mHEV 155

  2. Rear seat belt buckle poorly riveted (recall 23S31)

    Manufacturer recall

    On Focus models built in 2023, the riveting of the rear seat belt buckle may be incomplete, which can reduce restraint in a crash. Ford inspects the buckle at the workshop and replaces it if necessary.

    Fixed free of charge by a dealer and not counted in the reliability score: ask for proof the work was done (invoice, or a VIN check at a dealer).

1.5 EcoBlue 95

  1. Cracked particulate filter on EcoBlue diesels (recall 24E06)

    Manufacturer recall

    Ford is recalling vehicles fitted with the 1.5-litre and 2.0-litre EcoBlue diesels, including the Focus, because the particulate filter can crack: soot emissions can then exceed the limit and cause a failure at the MOT test. The free repair includes a software update of the engine control unit, then an inspection of the filter, which is only replaced if cracked. Sources do not give the same production period: check the serial number with Ford.
