2020 Kia Optima: 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
83% pass first time (all 2020 cars: 87%)
Stands out: brake pads 2.2×
290 MOTsSee the diesel guide ›
Hybrid
91% pass first time (all 2020 cars: 87%)
Nothing stands out above the usual rate
130 MOTsSee the hybrid guide ›
Petrol versions had too few MOTs for figures of their own, or weren’t sold.
