Kia Sedona 2004: MOT failure rate for its age
56.9% of 3,644 MOT tests of the Kia Sedona first registered in 2004 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 105.7 (95% CI 101.1–110.2; 100 = normal for this model at that age): the 2004 Kia Sedona fails more often than other build years of the same model at the same age. This is a rough estimate from a smaller sample.
| Measure | Value | Unit | Compared with | Years | Tests |
|---|---|---|---|---|---|
| Failed first time | 56.9 | % | all ages tested | 2019–2024 | 3644 |
| Index against this model at the same age (95% CI 101.1–110.2) | 105.7 | index | 100 = normal for this model at that age | 2019–2024 | 3644 |
| Rank among this model's 11 build years | 10 | of 11 | 1 = fails least for its age | 2019–2024 | 3644 |
| Tested in 2024 | 213 | tests | median 102,256 miles | 2024 | 213 |

How does the 2004 Kia Sedona fail at each age?
Cars built in 2004 were tested at ages 15 to 20 between 2019 and 2024. Each row compares their first-time failure share with what this model normally shows at that age, after allowing for the overall failure level of each test year.

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.
