Is the Yaris getting worse?
The fail rate rose 0.2 points to 20.5% from 2022 to 2025, against a rising rate across all cars.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 442,092 | 10 | 20.3% | 22.5% | |
| 2023 | 447,231 | — | 20.5% | 22.8% | |

| 2025 | 423,975 | — | 20.5% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Yaris at its test that year, and it is the number to watch: across the whole fleet each extra year of age adds roughly 1.9 points to the fail rate, so a model whose age and fail rate rise together is simply getting older.
The exact defects that fail it
Every failure item DVSA recorded against a Yaris in 2025, counted by how many tests each one appeared on.

- 3Wipers: does not clear the windscreen effectively8,079 tests

What wears out first
Advisories are the tester flagging wear that is still legal. A typical Yaris collects 2.95 of them per test, and these are the ones that come up most. Treat it as the running-repairs list for the next year or two.
