Subaru WRX MOT pass rate and common failures
In 2025, 88.6% of Subaru WRX MOT tests were a first-time pass, across 1,805 tests in Great Britain. For all cars it was 71.5%.
Compared with cars of the same age
Older cars fail more often, so a model that’s mostly a few years old will look better than one that’s mostly 12. These figures compare like with like.
At 3–5 years
–
Too few tests at this age to say.
At 6–10 years
90.9%
All cars: 76.1% (14.8 points better). 1,190 tests.
At 11 years and over
82.5%
All cars: 61.3% (21.2 points better). 520 tests.

Most common reasons for failing

- Position lamp: not working failed 0.9% of tests · what this means
- Catalyst emissions: carbon monoxide content after 2nd fast idle exceeds default limits failed 0.8% of tests · what this means
- Catalyst emissions: carbon monoxide content at idle exceeds manufacturer's specified limits failed 0.8% of tests · what this means

About these figures
- They cover every WRX version DVSA records under this name (engines, trims and generations together), on its first MOT test of each visit. A “pass with rectification” (fixed within an hour) counts as a fail, as in DVSA’s own statistics.
- Cars under three years old are left out, because the few tested that young are mostly taxis.
- Fuel mix of the cars tested: petrol 100.0%.
- A pass rate describes the model, not any one car. How a car has been looked after matters more.
