# Opel Kadett MOT reliability: pass rate and common failures | RegFlags

The Opel Kadett passed its MOT first time 88% of the time, but from only 34 MOT tests, so treat it as a rough guide. See pass rates by year, common failures and typical mileage.

- First-time MOT pass rate: 88%
- MOT tests analysed: 34 (DVSA anonymised MOT data, 2025)
- Most common failure area: Lights & electrics
- Licensed in Great Britain: 106 (2026 Q2)

These figures come from 34 MOT tests. That's a fairly small number of cars, so they may not be typical of these cars as a whole.
