Advisories to look for in a Toyota Yaris'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 Toyota Yaris, 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 edge222.4
  • Tyres: slightly damaged/cracking or perishing179.4
  • Rigid brake pipes: corroded, covered in grease or other material108.0
  • Brake discs: worn, pitted or scored, but not seriously weakened105.9
  • Suspension arms: pin or bush worn but not resulting in excessive movement105.5
  • Coil spring: corroded66.8

Checking a used Toyota Yaris before you buy

The Toyota Yaris has no part of the car that fails well above average for its age, so check the areas that fail most often overall.

  • Lights and electrics

    Walk round the car with every light on: headlights on dip and main beam, indicators, brake lights, fog lights and the number plate lamp. A pattern of electrical faults costs more than a bulb.

  • Suspension

    Drive over speed bumps with the radio off and listen for knocks. Look at the car side on: a corner sitting lower than the others often means a broken coil spring.

  • 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 Toyota Yaris cars tested: Petrol 63%, Hybrid 32%, Diesel 5%. Average age at test 10.9 years, average recorded mileage 62,000.

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 Toyota Yaris 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.
