Is the Grand Modus getting worse?
The fail rate rose 3.6 points to 42% from 2022 to 2025 while the median one tested aged 3 years, which is about what ageing alone predicts (5.3 points). Read it as the fleet getting older rather than the model changing.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 3,515 | 12 | 38.4% | 22.5% | |
| 2023 | 3,358 | 13 | 40.2% | 22.8% | |
| 2024 | 2,676 | 14 | 40.6% | 23.2% | |
| 2025 | 2,577 | 15 | 42% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Grand Modus 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 Grand Modus in 2025, counted by how many tests each one appeared on.
- 1Coil spring: fractured or broken354 tests
- 2Track rod end: ball joint has excessive play213 tests
- 3Position lamp: not working178 tests
- 4Ball joint: ball joint excessively worn159 tests
- 5Stop lamp: not working103 tests
- 6Linkage ball joint dust cover: ball joint dust cover no longer prevents the ingress of dirt93 tests
- 7Headlamp: not working on dipped beam84 tests
- 8Tread depth: tread depth below requirements of 1.6mm83 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical Grand Modus collects 2.8 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.
- 1Tread depth: tread depth below requirements of 1.6mm525 tests
- 2Brake discs: in such a condition that it is seriously weakened406 tests
- 3Condition: has a tear, caused by separation or partial failure of its structure288 tests
- 4Engine oil leaks: leaking excessively from engine233 tests
- 5Track rod end: ball joint has excessive play189 tests
- 6Rigid brake pipes: excessively corroded168 tests
- 7Brake pads: less than 1.5 mm thick163 tests
- 8Coil spring: corroded so that its cross sectional area is reduced and seriously weakened137 tests
