2021 Hyundai i30: 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.

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

  • Sunroof and tyre pressure recalls

    Some cars

    A few cars built Sept to Oct 2018 were recalled for the sunroof anti-trap sensor, and cars built June 2020 to Sept 2021 for tyre pressure monitoring software.

    At the viewing: Ask a Hyundai dealer to confirm any recalls were done.
