Is the Rodeo getting worse?
The fail rate rose 1.4 points to 37.6% from 2022 to 2025 while the median one tested aged 3 years, which is about what ageing alone predicts (3.3 points). Read it as the fleet getting older rather than the model changing.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 6,057 | 14 | 36.2% | 22.5% | |
| 2023 | 5,491 | 15 | 37.6% | 22.8% | |
| 2024 | 4,419 | 16 | 37.3% | 23.2% | |
| 2025 | 3,943 | 17 | 37.6% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Rodeo 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 Rodeo in 2025, counted by how many tests each one appeared on.
- 1Ball joint: ball joint excessively worn274 tests
- 2Rear fog lamp: not working251 tests
- 3Position lamp: not working237 tests
- 4Headlamp aim: projected beam image is obviously incorrect172 tests
- 5Rigid brake pipes: excessively corroded154 tests
- 6Stop lamp: not working154 tests
- 7Exhaust system: has a major leak of exhaust gases135 tests
- 8Component mounting prescribed areas: prescribed area excessively corroded significantly reducing structural strength132 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical Rodeo collects 3.62 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.
- 1Rigid brake pipes: excessively corroded870 tests
- 2Wheel bearings: has excessive play791 tests
- 3Tread depth: tread depth below requirements of 1.6mm558 tests
- 4Engine oil leaks: leaking excessively from engine413 tests
- 5Chassis condition: corroded to the extent that the rigidity of the assembly is significantly reduced410 tests
- 6Ball joint: ball joint excessively worn369 tests
- 7Exhaust system: has a major leak of exhaust gases239 tests
- 8Shock absorbers: has an excessively worn bush232 tests
Questions
What is the Isuzu Rodeo MOT pass rate?
62.8% of the 4,064 Isuzu Rodeo first-attempt MOTs in 2025 passed. The fail rate of 37.2% compares with 22.6% across all cars. A further 7.6% passed after a defect was fixed during the test visit.
What does a Isuzu Rodeo usually fail on?
The single most common failure is "Ball joint: ball joint excessively worn", recorded on 274 failed tests, followed by "Rear fog lamp: not working" and "Position lamp: not working". By section, lamps, reflectors and electrical equipment appears in 58.9% of failures, suspension appears in 56.6% of failures, brakes appears in 39.5% of failures.
Does age change the odds?
Sharply. At 3 to 5 years old the fail rate was n/a%; at 14+ years it was 37%. The median Isuzu Rodeo tested in 2025 was 17 years old with 126,981 miles.
Is the Isuzu Rodeo getting less reliable?
The fail rate rose 1.4 points to 37.6% from 2022 to 2025 while the median one tested aged 3 years, which is about what ageing alone predicts (3.3 points). Read it as the fleet getting older rather than the model changing.
