Is the Grand Cherokee getting worse?
The fail rate rose 3.5 points to 18.3% from 2022 to 2025 while the median one tested aged 3 years. Ageing alone would predict about 7.7 points, so it is holding up better than the fleet average for its age.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 6,588 | 7 | 14.8% | 22.5% | |
| 2023 | 6,556 | 8 | 14.7% | 22.8% | |
| 2024 | 5,571 | 9 | 16.9% | 23.2% | |
| 2025 | 5,806 | 10 | 18.3% | 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.
- 1Ball joint dust cover: ball joint dust cover no longer prevents the ingress of dirt171 tests
- 2Brake pads: less than 1.5 mm thick161 tests
- 3Tread depth: tread depth below requirements of 1.6mm158 tests
- 4Ball joint: ball joint excessively worn142 tests
- 5Position lamp: not working139 tests
- 6Malfunction indicator lamp: inoperative or indicates a malfunction134 tests
- 7Rbt (sp): efficiency below requirements131 tests
- 8Headlamp: not working on dipped beam126 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical Grand Cherokee collects 2.92 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.
