A pass rate records whether cars met the roadworthiness standard on test day. It is not a reliability score, and part of any gap reflects how old the tested cars were.
I30 MOT pass rate by age
The same 2025 tests split by the car's age at test.
Hyundai I30 cars aged 3 to 5 years passed 87% of MOT tests. For cars aged 11 years and over that fell to 54.6%, a drop of 32.4 percentage points.
| Age at test | Tests | Pass rate | vs UK average |
|---|---|---|---|
| 3 to 5 years | 6,721 | 87% | 14.7 pts above |
| 6 to 10 years | 43,469 | 72.2% | In line |
| 11 years and over | 50,675 | 54.6% | 17.7 pts below |
That is a steep decline with age, so the headline rate flatters older examples. The UK average of 72.3% covers cars of every age, so compare like with like.
