I40 MOT pass rate by age
The same 2025 tests split by the car's age at test.
Hyundai I40 cars aged 3 to 5 years passed 83.9% of MOT tests. For cars aged 11 years and over that fell to 62.7%, a drop of 21.2 percentage points.
| Age at test | Tests | Pass rate | vs UK average |
|---|---|---|---|
| 3 to 5 years | 316 | 83.9% | 11.6 pts above |
| 6 to 10 years | 12,220 | 75.9% | 3.6 pts above |
| 11 years and over | 7,304 | 62.7% | 9.7 pts below |
