2021 Ford Fiesta: petrol or diesel?

Petrol, diesel and hybrid versions go wrong in different ways, so each has its own figures from the MOTs these cars had during 2023–2025. Pick the one you’re looking at: the fuel is on the logbook and in the car’s MOT history.

Petrol and Diesel versions had too few MOTs for figures of their own, or weren’t sold.

Known faults on every 2021 Ford Fiesta

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.

  • 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.
