Advisories to look for in a Suzuki SX4's MOT history

An advisory is a tester's warning that something is wearing but has not failed yet. These are the ones written most often on the Suzuki SX4, per 1,000 tests. If the car you are looking at has one of these, ask whether it has been fixed since.

  • Tread depth: worn close to legal limit/worn on edge296.2
  • Rigid brake pipes: corroded, covered in grease or other material181.7
  • Tyres: slightly damaged/cracking or perishing125.4
  • Brake discs: worn, pitted or scored, but not seriously weakened114.6
  • Brake pads: wearing thin90.3
  • Suspension arms: pin or bush worn but not resulting in excessive movement71.1

Checking a used Suzuki SX4 before you buy

Against cars of the same age, the Suzuki SX4 fails more often than average on brakes. Start there.

  • Brakes

    Look through the wheel spokes at the discs for a deep lip or scoring, check the handbrake holds the car on a slope, and feel for a pull to one side when braking hard.

Averages only take you so far. The specific car's MOT history shows whether it has already failed on any of these, how often advisories were ignored, and whether the mileage climbs steadily from test to test. Read our guide to reading a car's MOT history before you go to view it.

Fuel mix of the Suzuki SX4 cars tested: Petrol 77%, Diesel 12%, Hybrid 11%. Average age at test 10.6 years, average recorded mileage 67,900.

How these figures are calculated

Source: DVSA Anonymised MOT tests and results, 2025 release. We count first tests of cars and small vans (class 4) aged 3 to 20, so a car that fails and is retested is counted once. A failure includes faults fixed and passed within the same visit. The same age average weights the national failure rate for each age by how many Suzuki SX4 cars of that age were tested, so a model is never penalised for having an older fleet. Make and model are as recorded at the test; trim levels are combined. Full method and rankings.
