Is the I800 getting worse?
The fail rate rose 1.7 points to 27% from 2022 to 2025 while the median one tested aged 3 years. Ageing alone would predict about 6.6 points, so it is holding up better than the fleet average for its age.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 8,416 | 5 | 25.3% | 22.5% | |
| 2023 | 8,337 | 6 | 25.6% | 22.8% | |
| 2024 | 7,161 | 7 | 27.3% | 23.2% | |
| 2025 | 7,385 | 8 | 27% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical I800 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 I800 in 2025, counted by how many tests each one appeared on.
- 1Position lamp: not working401 tests
- 2Headlamp aim: projected beam image is obviously incorrect264 tests
- 3Rbt (sp): efficiency below requirements261 tests
- 4Registration plate lamp(s): inoperative in the case of a single lamp or all lamps242 tests
- 5Headlamp: not working on dipped beam235 tests
- 6Malfunction indicator lamp: inoperative or indicates a malfunction235 tests
- 7Brake pads: less than 1.5 mm thick221 tests
- 8Parking brake performance: inoperative on one side190 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical I800 collects 2.74 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 1.6mm1,266 tests
- 2Brake pads: less than 1.5 mm thick920 tests
- 3Brake discs: in such a condition that it is seriously weakened740 tests
- 4Engine oil leaks: leaking excessively from engine443 tests
- 5Non-component advisories: Child Seat fitted not allowing full inspection of adult belt394 tests
- 6Rigid brake pipes: excessively corroded344 tests
- 7Condition: has a tear, caused by separation or partial failure of its structure317 tests

What does a Hyundai I800 usually fail on?
The single most common failure is "Position lamp: not working", recorded on 401 failed tests, followed by "Headlamp aim: projected beam image is obviously incorrect" and "Rbt (sp): efficiency below requirements". By section, lamps, reflectors and electrical equipment appears in 54.7% of failures, brakes appears in 45.3% of failures, suspension appears in 22% of failures.
Does age change the odds?
Sharply. At 3 to 5 years old the fail rate was 18.6%; at 14+ years it was 37.2%. The median Hyundai I800 tested in 2025 was 8 years old with 83,204 miles.
Is the Hyundai I800 getting less reliable?
The fail rate rose 1.7 points to 27% from 2022 to 2025 while the median one tested aged 3 years. Ageing alone would predict about 6.6 points, so it is holding up better than the fleet average for its age.
