Suzuki SX4 years to avoid? MOT pass rate by year

36,357 initial MOT tests in 2025 on cars first used 2007–2019 · DVSA data · For guidance only · How we count

Suzuki SX4 years with MOT pass rates below the average for vehicles first used in the same year: 2007–2012. Above it: 2014–2019. The other year can't be told apart from average.

The MOT pass rate is one signal, not the whole story. An MOT checks safety and emissions on the day of the test. It doesn't record gearbox or engine faults, and a pass rate also reflects mileage and upkeep, so the table shows median mileage too. Whatever the year, the car in front of you matters more than its model's average.

69.4%passed first time

First-time pass rate, all years together: initial tests passed with no repairs. 95% range 68.9% to 69.8%.

In 2025, 69.4% of the 36,357 initial MOT tests on Suzuki SX4 cars were passed with no repairs. The same-age average, for all vehicles first used in the same years, was 68.9%. That is about average: the difference from the same-age average is within the margin of error.

Suzuki SX4 MOT pass rate by year

Year is when the car was first used. Older vehicles fail more often, so each year is compared with all vehicles first used that year.

Tests are initial MOT tests in 2025, not retests. Median miles is the middle odometer reading at the test: half had more, half had less. ± is the 95% margin of error in points (Wilson interval): a difference smaller than that could be chance. Years without a link have fewer than 10,000 tests, so they are listed here but don't have their own page.

When a car's mileage doesn't add up

Does mileage matter?

Suzuki SX4 first-time pass rates by the mileage at the initial test, all years together, against all vehicles of the same age and mileage.

88.5% of Suzuki SX4 tests under 30,000 miles passed first time, against 49.5% at 120,000 miles or more. For all vehicles of the same age and mileage, the figures are 86.8% and 58.6%.

120,000 or more3,24549.5%±1.8−9.1 ptsall: 58.6%

Against all vehicles of the same age and mileage, SX4 tests were above average under 60,000 miles, about average at 60,000 to 89,999 miles and below average at 90,000 miles or more.

Mileage is only one factor. How a car has been driven and looked after matters too. These figures show an association across all Suzuki SX4 tests in 2025, not what mileage does to a particular car.

Mileage is the odometer reading at the initial test. Each band is compared with all vehicles first used in the same year with a reading in the same band, weighted by this model's own tests in each year. Bands need at least 1,000 tests. 10 tests (under 0.1%) had no usable odometer reading and are left out. How we count

Common SX4 problems at the MOT

Share of the 11,143 failed tests with a fault in each area, all years together. A test can count in more than one area, so these add up to more than 100%.

MOT records show roadworthiness faults, not engine or gearbox problems. Each year page compares that year's failure areas with all vehicles first used in the same year.

What to check when viewing a SX4

Based on the areas where Suzuki SX4 MOT tests fail most often. These are general checks anyone can do, not a mechanical inspection.

  1. Suspension

    In 39.6% of failed SX4 tests

    • Push down hard on each corner. The car should rise once and settle, not keep bouncing.
    • On the test drive, listen for knocks or clunks over speed bumps and potholes.
    • The car should sit level when parked on flat ground.

  2. Lights and electrics

    In 34.1% of failed SX4 tests

    • Ask the seller to help you check every light: dipped and main beam, brake lights, indicators, fog lights and the number plate lamp.
    • Look for cracked, misted or yellowed headlight lenses.
    • Warning lights on the dashboard should come on with the ignition and go out once the engine starts.

  3. Brakes

    In 29.7% of failed SX4 tests

    • On a clear road, brake firmly. The car should stop in a straight line without juddering or pulling to one side.
    • Check the handbrake holds the car on a slope.
    • Look through the wheels at the brake discs for deep grooves or a raised lip at the edge.

  4. Tyres

    In 21.0% of failed SX4 tests

    • Check the tread on every tyre. The legal minimum for cars is 1.6 mm across the central three-quarters of the tread.
    • Look for cuts, bulges, and wear on only the inner or outer edge, which can point to an alignment problem.
    • Check that the spare wheel or the tyre repair kit is there.

Then read the car's own MOT history. Advisories in the same area at several tests are worth asking about.

Tyres

Of Suzuki SX4 cars that passed their 2024 MOT with a tyre advisory and came back for their next MOT 10–14 months later, 8.8% failed on tyres, against 4.4% of similar cars with nothing noted. Based on 4,784 and 15,872 cars.

Brakes

Of Suzuki SX4 cars that passed their 2024 MOT with a brake advisory and came back for their next MOT 10–14 months later, 12.1% failed on brakes, against 6.5% of similar cars with nothing noted. Based on 4,864 and 15,769 cars.

Suspension

Of Suzuki SX4 cars that passed their 2024 MOT with a suspension advisory and came back for their next MOT 10–14 months later, 23.3% failed on suspension, against 15.2% of similar cars with nothing noted. Based on 2,667 and 17,269 cars.

  • With a suspension advisory23.3%
  • Similar cars, nothing noted15.2%

Cars not tested again in that window are not included: 14.2% of those with a suspension advisory and 8.3% of the others.

Similar cars are the same model, first-use year and mileage band. Areas are the DVSA's top-level groups, so the later fail may not be the fault that was advised. These figures describe what happened to these cars. They don't show what a repair would have changed.

Suzuki SX4 questions

Which Suzuki SX4 years have lower MOT pass rates?

Compared with all vehicles first used in the same year, these model years have below-average MOT pass rates: 2007–2012. Above average: 2014–2019. The rest can't be told apart from average. A pass rate is one signal: it also reflects mileage and upkeep, and doesn't record engine or gearbox faults.

Is the Suzuki SX4 reliable?

MOT results show only part of the picture. In 2025, 69.4% of initial MOT tests on Suzuki SX4 cars were passed with no repairs, against a same-age average of 68.9%. That is about average. An MOT checks safety and emissions on the day of the test. It doesn't measure breakdowns, engine or gearbox faults, or repair costs.

What are the most common Suzuki SX4 problems at the MOT?

The most common failure areas are suspension (in 39.6% of failed tests), lights and electrics (in 34.1% of failed tests) and brakes (in 29.7% of failed tests). A failed test can count in more than one area.

What mileage is normal for a 10-year-old Suzuki SX4?

At their 2025 MOT tests, Suzuki SX4 cars first used in 2015, about 10 years old, had a median of 69,900 miles. Half had more and half had less.

How do I check a specific SX4's MOT history?

Enter its registration in our free check. It lists that car's own MOT results, the faults and advisories recorded and the mileage at each test, and flags repeated advisories and mileage that goes down.

What MOT data can't tell you about any Suzuki SX4

Outstanding finance, write-offs, theft and plate changes aren't in MOT records. For a particular car, you need a history check.
