Is the Auto-Sleepers getting worse?
The fail rate rose 2.2 points to 7.7% from 2022 to 2025 while the median one tested aged 2 years, which is about what ageing alone predicts (4.2 points). Read it as the fleet getting older rather than the model changing.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 689 | 5 | 5.5% | 22.5% | |
| 2023 | 772 | 5 | 6.6% | 22.8% | |
| 2024 | 835 | 6 | 9% | 23.2% | |
| 2025 | 1,031 | 7 | 7.7% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Auto-Sleepers 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 Auto-Sleepers in 2025, counted by how many tests each one appeared on.
- 1Wipers: does not clear the windscreen effectively17 tests
- 2Position lamp: not working6 tests
- 3SRS malfunction indicator lamp: warning lamp indicates a fault6 tests
- 4Washers: not working6 tests
- 5Lever: has excessive movement indicating incorrect adjustment5 tests
- 6Component mounting prescribed areas: prescribed area excessively corroded significantly reducing structural strength4 tests
- 7Malfunction indicator lamp: inoperative or indicates a malfunction4 tests
- 8Service brake performance: excessively binding4 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical Auto-Sleepers collects 2.34 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.
- 1Condition: has a tear, caused by separation or partial failure of its structure39 tests
- 2Brake discs: in such a condition that it is seriously weakened23 tests
- 3Tread depth: tread depth below requirements of 1.6mm22 tests
- 4Pins and bushes: pin or bush excessively worn21 tests
- 5Engine oil leaks: leaking excessively from engine15 tests
- 6Registration plates: inscription illegible9 tests
