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 75% pass first time (all 2010 cars: 60%) Stands out: anti-roll bar link bushes 11.7× 886 MOTsSee the petrol guide › Diesel 70% pass first time (all 2010 cars: 60%) Stands out: anti-roll bar link bushes 16.8×, engine warning light 2.2×, seat belts 2× 19,059 MOTsSee the diesel guide ›

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