Is the I30 getting worse?
The fail rate rose 3.5 points to 29.3% from 2022 to 2025 while the median one tested aged 2 years. Ageing alone would predict about 5.2 points, so it is holding up better than the fleet average for its age.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 107,397 | 9 | 25.8% | 22.5% | |
| 2023 | 106,669 | 9 | 27.5% | 22.8% | |
| 2024 | 90,491 | 10 | 29.4% | 23.2% | |
| 2025 | 92,125 | 11 | 29.3% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical I30 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 I30 in 2025, counted by how many tests each one appeared on.
- 1Rbt (sp): efficiency below requirements4,491 tests
- 2Track rod end: ball joint has excessive play3,926 tests
- 3Stop lamp: not working3,236 tests
- 4Tread depth: tread depth below requirements of 1.6mm2,727 tests
- 5Position lamp: not working2,392 tests
- 6Parking brake performance: inoperative on one side2,382 tests
- 7Brake pads: less than 1.5 mm thick2,324 tests

What wears out first
Advisories are the tester flagging wear that is still legal. A typical I30 collects 2.89 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.

Questions
What is the Hyundai I30 MOT pass rate?
71.3% of the 95,114 Hyundai I30 first-attempt MOTs in 2025 passed. The fail rate of 28.7% compares with 22.6% across all cars. A further 6.8% passed after a defect was fixed during the test visit.
What does a Hyundai I30 usually fail on?
The single most common failure is "Rbt (sp): efficiency below requirements", recorded on 4,491 failed tests, followed by "Track rod end: ball joint has excessive play" and "Stop lamp: not working". By section, brakes appears in 41.1% of failures, lamps, reflectors and electrical equipment appears in 36.7% of failures, suspension appears in 33.4% of failures.
Does age change the odds?
Sharply. At 3 to 5 years old the fail rate was 10.5%; at 14+ years it was 37.8%. The median Hyundai I30 tested in 2025 was 11 years old with 77,986 miles.
Is the Hyundai I30 getting less reliable?
The fail rate rose 3.5 points to 29.3% from 2022 to 2025 while the median one tested aged 2 years. Ageing alone would predict about 5.2 points, so it is holding up better than the fleet average for its age.
