What the 370z fails on
Share of failed tests with at least one fail item in each DVSA inspection section. A test can fail in several sections at once.

- Identification of the vehicle2.8%
Is the 370z getting worse?
The fail rate rose 0.3 points to 12.2% from 2022 to 2025 while the median one tested aged 2 years. Ageing alone would predict about 3.7 points, so it is holding up better than the fleet average for its age.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 1,736 | 12 | 11.9% | 22.5% | |
| 2023 | 1,719 | 12 | 13.1% | 22.8% | |
| 2024 | 1,558 | 13 | 14.4% | 23.2% | |
| 2025 | 1,612 | 14 | 12.2% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical 370z 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 370z in 2025, counted by how many tests each one appeared on.
- 1Catalyst emissions: Lambda reading after 2nd fast idle outside specified limits31 tests
- 2Tread depth: tread depth below requirements of 1.6mm27 tests
- 3Exhaust system: has a major leak of exhaust gases18 tests
- 4Catalyst emissions: carbon monoxide content after 2nd fast idle exceeds manufacturer's specified limits17 tests
- 5Headlamp aim: projected beam image is obviously incorrect15 tests
- 6Wipers: does not clear the windscreen effectively13 tests
- 7Washers: not working12 tests
- 8Condition: has a cut in excess of the requirements deep enough to reach the ply or cords12 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical 370z collects 2.5 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 1.6mm222 tests
- 2Brake discs: in such a condition that it is seriously weakened114 tests
- 3Sub-frame: corroded and seriously weakened98 tests
- 4Linkage ball joints: ball joint excessively worn93 tests
- 5Rigid brake pipes: excessively corroded86 tests
- 6Condition: has a tear, caused by separation or partial failure of its structure67 tests
- 7Exhaust system: has a major leak of exhaust gases56 tests
- 8Headlamp: has a product on the lens so that the light output is severely reduced27 tests
Questions
What is the Nissan 370z MOT pass rate?
88% of the 1,777 Nissan 370z first-attempt MOTs in 2025 passed. The fail rate of 12% compares with 22.6% across all cars. A further 2.3% passed after a defect was fixed during the test visit.
What does a Nissan 370z usually fail on?
The single most common failure is "Catalyst emissions: Lambda reading after 2nd fast idle outside specified limits", recorded on 31 failed tests, followed by "Tread depth: tread depth below requirements of 1.6mm" and "Exhaust system: has a major leak of exhaust gases". By section, noise, emissions and leaks appears in 33.3% of failures, lamps, reflectors and electrical equipment appears in 27.7% of failures, tyres appears in 25.8% of failures.
Does age change the odds?
Sharply. At 3 to 5 years old the fail rate was 6.6%; at 14+ years it was 13.7%. The median Nissan 370z tested in 2025 was 14 years old with 58,982 miles.
Is the Nissan 370z getting less reliable?
The fail rate rose 0.3 points to 12.2% from 2022 to 2025 while the median one tested aged 2 years. Ageing alone would predict about 3.7 points, so it is holding up better than the fleet average for its age.
