# Chevrolet Gmc Blazer MOT reliability: pass rate and common failures | RegFlags

The Chevrolet Gmc Blazer passed its MOT first time 70% of the time, but from only 56 MOT tests, so treat it as a rough guide. See pass rates by year, common failures and typical mileage.

- First-time MOT pass rate: 70%
- MOT tests analysed: 56 (DVSA anonymised MOT data, 2025)
- Most common failure area: Lights & electrics
- Licensed in Great Britain: 43 (2026 Q2)

These figures come from 56 MOT tests. That's a fairly small number of cars, so they may not be typical of these cars as a whole.
