Brake efficiency below requirements on the Hyundai I30
Brake efficiency below requirements on the Hyundai I30 is recorded on 14,680 tests — 3.8% of all its MOT tests, against 0.9% across every car in the data. That is 4.2× the national share.
Is this unusual for this model?
| Compared with | What it says |
|---|---|
| Every car in the data | 0.9% of tests record it — this model is 4.2× that share |
| The 283 models compared | 12 of 283, highest first |
| The model's own record | 388,487 tests · every year of the I30 → |
A share of tests is not a probability for your car: it counts every Hyundai I30 tested, whatever its mileage, service history and use. The like-for-like comparison on the model page is the fairer number.

Years with fewer than 0.2% of tests recording the item are left out: a year with two failures in 400 tests is noise, and this table is not here to make noise look like a trend.
