Is the Sx4 getting worse?
The fail rate rose 2.9 points to 25.5% from 2022 to 2025 while the median one tested aged 3 years. Ageing alone would predict about 8 points, so it is holding up better than the fleet average for its age.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 41,450 | 8 | 22.6% | 22.5% | |
| 2023 | 40,742 | 9 | 24.2% | 22.8% | |
| 2024 | 34,015 | 10 | 25.2% | 23.2% | |
| 2025 | 34,699 | 11 | 25.5% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Sx4 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 Sx4 in 2025, counted by how many tests each one appeared on.
- 1Coil spring: fractured or broken1,613 tests
- 2Ball joint: ball joint excessively worn1,374 tests
- 3Tread depth: tread depth below requirements of 1.6mm1,279 tests
- 4Rigid brake pipes: excessively corroded786 tests
- 5Position lamp: not working767 tests
- 6Wipers: does not clear the windscreen effectively750 tests
- 7Brake pads: less than 1.5 mm thick690 tests
- 8Rbt (sp): efficiency below requirements649 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical Sx4 collects 2.96 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 1.6mm6,790 tests
- 2Rigid brake pipes: excessively corroded4,087 tests
- 3Brake discs: in such a condition that it is seriously weakened3,338 tests
- 4Condition: has a tear, caused by separation or partial failure of its structure3,250 tests

Questions
What is the Suzuki Sx4 MOT pass rate?
77.1% of the 39,469 Suzuki Sx4 first-attempt MOTs in 2025 passed. The fail rate of 22.9% compares with 22.6% across all cars. A further 5.3% passed after a defect was fixed during the test visit.
What does a Suzuki Sx4 usually fail on?
The single most common failure is "Coil spring: fractured or broken", recorded on 1,613 failed tests, followed by "Ball joint: ball joint excessively worn" and "Tread depth: tread depth below requirements of 1.6mm". By section, suspension appears in 47.3% of failures, brakes appears in 35.4% of failures, lamps, reflectors and electrical equipment appears in 26.3% of failures.
Does age change the odds?
Sharply. At 3 to 5 years old the fail rate was 4.3%; at 14+ years it was 39.4%. The median Suzuki Sx4 tested in 2025 was 11 years old with 64,796 miles.
Is the Suzuki Sx4 getting less reliable?
The fail rate rose 2.9 points to 25.5% from 2022 to 2025 while the median one tested aged 3 years. Ageing alone would predict about 8 points, so it is holding up better than the fleet average for its age.
