Is the Insignia getting worse?
The fail rate rose 2.2 points to 26.9% from 2022 to 2025 while the median one tested aged 3 years. Ageing alone would predict about 8 points, so it is holding up better than the fleet average for its age.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 230,535 | 8 | 24.7% | 22.5% | |
| 2023 | 216,995 | 9 | 26.2% | 22.8% | |
| 2024 | 177,747 | 10 | 26.2% | 23.2% | |
| 2025 | 168,443 | 11 | 26.9% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Insignia 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.
