# Knaus Sun MOT reliability: pass rate and common failures | RegFlags

The Knaus Sun passed its MOT first time 89% of the time, but from only 96 MOT tests, so treat it as a rough guide. See pass rates by year, common failures and typical mileage.

- First-time MOT pass rate: 89%
- MOT tests analysed: 96 (DVSA anonymised MOT data, 2025)
- Most common failure area: Brakes
- Licensed in Great Britain: 13 (2026 Q2)

These figures come from 96 MOT tests. That's a fairly small number of cars, so they may not be typical of these cars as a whole.
