2021 Hyundai Ioniq: 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.
Hybrid
87% pass first time (all 2021 cars: 87%)
Stands out: headlight aim 1.8×
15,294 MOTsSee the hybrid guide ›
Electric
90% pass first time (all 2021 cars: 87%)
Nothing stands out above the usual rate
12,226 MOTsSee the electric guide ›
Petrol and Diesel versions had too few MOTs for figures of their own, or weren’t sold.
