Is the Stinger getting worse?
The fail rate rose 1.2 points to 9.9% from 2022 to 2025 while the median one tested aged 3 years. Ageing alone would predict about 4.2 points, so it is holding up better than the fleet average for its age.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 1,754 | 3 | 8.7% | 22.5% | |
| 2023 | 1,929 | 4 | 9.7% | 22.8% | |
| 2024 | 1,789 | 5 | 11.1% | 23.2% | |
| 2025 | 2,019 | 6 | 9.9% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Stinger 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 Stinger in 2025, counted by how many tests each one appeared on.
- 1Tread depth: tread depth below requirements of 1.6mm38 tests
- 2Brake pads: less than 1.5 mm thick38 tests
- 3Condition: has ply or cords exposed27 tests
- 4Condition: has a cut in excess of the requirements deep enough to reach the ply or cords27 tests
- 5Wipers: does not clear the windscreen effectively10 tests
- 6Tyre pressure monitoring system: malfunctioning or obviously inoperative9 tests
- 7Malfunction indicator lamp: inoperative or indicates a malfunction8 tests
- 8Condition: has a bulge, caused by separation or partial failure of its structure8 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical Stinger collects 2.11 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.
- 1Tread depth: tread depth below requirements of 1.6mm298 tests
- 2Brake pads: less than 1.5 mm thick247 tests
- 3Brake discs: in such a condition that it is seriously weakened80 tests
- 4Condition: has a cut in excess of the requirements deep enough to reach the ply or cords57 tests
- 5Brake discs: significantly and obviously worn51 tests

- 7Tread depth: tread pattern not visible over the whole tread area when minimum depth required is 1.0mm43 tests

Questions
What is the Kia Stinger MOT pass rate?
90% of the 2,064 Kia Stinger first-attempt MOTs in 2025 passed. The fail rate of 10% compares with 22.6% across all cars. A further 2.1% passed after a defect was fixed during the test visit.
What does a Kia Stinger usually fail on?
The single most common failure is "Tread depth: tread depth below requirements of 1.6mm", recorded on 38 failed tests, followed by "Brake pads: less than 1.5 mm thick" and "Condition: has ply or cords exposed". By section, tyres appears in 53.6% of failures, brakes appears in 29% of failures, lamps, reflectors and electrical equipment appears in 9.7% of failures.
Does age change the odds?
Sharply. At 3 to 5 years old the fail rate was 8.8%; at 6-9 years it was 10.4%. The median Kia Stinger tested in 2025 was 6 years old with 42,394 miles.
Is the Kia Stinger getting less reliable?
The fail rate rose 1.2 points to 9.9% from 2022 to 2025 while the median one tested aged 3 years. Ageing alone would predict about 4.2 points, so it is holding up better than the fleet average for its age.
