Is the Grand Cherokee getting worse?
The fail rate fell 1.9 points to 27.5% from 2022 to 2025 while the median one tested aged 3 years, which is about what ageing alone predicts (1.1 points). Read it as the fleet getting older rather than the model changing.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 2,428 | 16 | 29.4% | 22.5% | |
| 2023 | 2,105 | 17 | 28.5% | 22.8% | |
| 2024 | 1,575 | 18 | 29.2% | 23.2% | |
| 2025 | 1,379 | 19 | 27.5% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Grand Cherokee 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 Cherokee in 2025, counted by how many tests each one appeared on.
- 1Component mounting prescribed areas: prescribed area excessively corroded significantly reducing structural strength53 tests
- 2Position lamp: not working42 tests
- 3Ball joint: ball joint excessively worn36 tests
- 4Rear fog lamp: not working33 tests
- 5Pins and bushes: pin or bush excessively worn30 tests
- 6Decelerometer (sp): efficiency below requirements29 tests
- 7Joints: constant velocity boot split or insecure, no longer prevents the ingress of dirt28 tests
- 8Rbt (sp): efficiency below requirements27 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical Grand Cherokee collects 3.82 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.
- 1Engine oil leaks: leaking excessively from engine225 tests
- 2Brake discs: in such a condition that it is seriously weakened197 tests
- 3Tread depth: tread depth below requirements of 1.6mm158 tests
- 4Pins and bushes: pin or bush excessively worn152 tests
- 5Coil spring: corroded so that its cross sectional area is reduced and seriously weakened146 tests
- 6Brake pads: less than 1.5 mm thick141 tests
- 7Ball joint: ball joint excessively worn130 tests
- 8Rigid brake pipes: excessively corroded123 tests
