Is the Wrangler getting worse?
The fail rate rose 0.6 points to 16.4% from 2022 to 2025 while the median one tested aged 1 year. Ageing alone would predict about 2.4 points, so it is holding up better than the fleet average for its age.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 3,392 | 7 | 15.8% | 22.5% | |
| 2023 | 3,874 | 7 | 16.5% | 22.8% | |
| 2024 | 3,787 | 7 | 16.5% | 23.2% | |
| 2025 | 4,487 | 8 | 16.4% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Wrangler 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.
