Is the Giulietta getting worse?
The fail rate rose 5.7 points to 30.3% from 2022 to 2025 while the median one tested aged 3 years. Ageing alone would predict about 7.4 points, so it is holding up better than the fleet average for its age.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 26,766 | 9 | 24.6% | 22.5% | |
| 2023 | 26,304 | 10 | 27% | 22.8% | |
| 2024 | 22,351 | 11 | 27.8% | 23.2% | |
| 2025 | 22,610 | 12 | 30.3% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Giulietta 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 Giulietta in 2025, counted by how many tests each one appeared on.
- 1Coil spring: fractured or broken1,228 tests

What wears out first
Advisories are the tester flagging wear that is still legal. A typical Giulietta collects 2.73 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.
