MG Hs reliability and MOT pass rate
91.5% passed first time. The 8.5% fail rate is 14.1 points better than the all-car average, on a median example 3 years old with 26,507 miles.

Is the Hs getting worse?
The fail rate rose 1.1 points to 8.5% from 2023 to 2025, against a falling rate across all cars.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2023 | 2,359 | — | 7.4% | 22.8% | |
| 2024 | 9,926 | — | 7.8% | 23.2% | |
| 2025 | 28,045 | — | 8.5% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Hs 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 Hs in 2025, counted by how many tests each one appeared on.
- 1Brake pads: less than 1.5 mm thick477 tests
- 2Condition: has a cut in excess of the requirements deep enough to reach the ply or cords404 tests
- 3Tyre pressure monitoring system: malfunctioning or obviously inoperative339 tests
- 4Brake discs: significantly and obviously worn236 tests
- 5Washers: not working171 tests
- 6Tread depth: tread depth below requirements of 1.6mm162 tests
- 7Malfunction indicator lamp: inoperative or indicates a malfunction123 tests
- 8Brake discs: in such a condition that it is seriously weakened97 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical Hs collects 2.06 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 MG Hs MOT pass rate?
91.5% of the 29,853 MG Hs first-attempt MOTs in 2025 passed. The fail rate of 8.5% compares with 22.6% across all cars. A further 3.2% passed after a defect was fixed during the test visit.
What does a MG Hs usually fail on?
The single most common failure is "Brake pads: less than 1.5 mm thick", recorded on 477 failed tests, followed by "Condition: has a cut in excess of the requirements deep enough to reach the ply or cords" and "Tyre pressure monitoring system: malfunctioning or obviously inoperative". By section, tyres appears in 39.4% of failures, brakes appears in 33.6% of failures, visibility appears in 13.5% of failures.
Does age change the odds?
Sharply. At 3 to 5 years old the fail rate was 8.7%; at 3-5 years it was 8.7%. The median MG Hs tested in 2025 was 3 years old with 26,507 miles.
Is the MG Hs getting less reliable?
The fail rate rose 1.1 points to 8.5% from 2023 to 2025, against a falling rate across all cars.
