In 2025, 37,484 Suzuki SX4 cars had a regular MOT in Great Britain. 69% passed first time, compared with 69% for all cars of the same ages, which makes the SX4 about average. Adjusted for age, it ranks 132 of the 217 most-tested car models.
That comparison matters: older cars fail more often, so a raw pass rate flatters models that are mostly young. We compare each model against every car on the road at the same age.
Pass rate by age
At 5 years old, 91% of SX4s passed first time (all cars that age: 86%). By 19 years, that figure is 47% (all cars: 57%). It starts out ahead of the average car but falls behind from around 13 years, which is worth knowing if you are buying an older one.

What to check when buying a used SX4
Based on where the SX4 fails more often than other cars, these are the checks worth making before you buy:
- Brakes: Look through the wheels for lipped or scored discs, check the handbrake holds on a slope, and feel for pulling or vibration under firm braking. Repair guide
- Suspension: Listen for knocks over speed bumps, look for leaking shock absorbers, and check the car sits level. Ask whether springs, bushes or drop links have been replaced. Repair guide
- Visibility: Check the windscreen for chips in the driver’s view, the wipers for smearing and the washers for working jets. Repair guide
Then check the individual car: its own MOT history will show whether it follows the pattern. A car with repeated advisories in the same weak area is more likely to fail its next test.
