Jeep Wrangler 2013: MOT failure rate for its age
28.7% of 965 MOT tests of the Jeep Wrangler first registered in 2013 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 106.8 (95% CI 94.2–119.4; 100 = normal for this model at that age): the 2013 build year is no different from other years of the same model at the same age. This is a rough estimate from a smaller sample.

| Failed first time | 28.7 | % | all ages tested | 2019–2024 | 965 |
| Index against this model at the same age (95% CI 94.2–119.4) | 106.8 | index | 100 = normal for this model at that age | 2019–2024 | 965 |
| Rank among this model's 10 build years | 5 | of 10 | 1 = fails least for its age | 2019–2024 | 965 |

How every figure is calculated: methodology. Age, test year and build year are tied together (age = test year − build year), so the test-year level is taken as observed, not estimated.
