The 2020 Mazda Mx-5 MOT pass rate is 95.4% of its MOT tests — 4.7 points ahead of what its age and mileage predict. Brakes is the biggest single reason it fails, at 37.6% of what testers record.
Expert verdict
Brakes: 1.8× the national share
Brakes make up 37.6% of everything recorded on the 2020 Mazda Mx-5, against 20.9% nationally — 16.7 points above. Have the discs and pads measured rather than glanced at, and ask whether the handbrake holds on a slope.
- Beats its own age and mileage. Once you allow for how old and how far these cars have been driven, the expected pass rate is 90.7% and this one manages 95.4% — 4.7 points ahead of what its age and mileage predict.
- When it fails, it costs. Only 32% of this model’s typical repairs come in under £30 in parts — the failures here tend to be the kind that need a garage rather than a bulb.

Where the Mazda Mx-5 is most common
Across all Mx-5 model years on record (2000–2022): 116,981 Mazda Mx-5 cars tested in a recordable postcode area, across 275,642 tests. Birmingham (B) has the most, with 2,700 cars tested there. Cars are counted by the postcode area of the MOT station, so this is where they were tested, not necessarily where their owners live.

The twenty areas with the most Mazda Mx-5 cars in the record, sorted by car count — sort the columns for a different question. Cars tested at a station whose postcode area could not be resolved are counted in the model's total but in no area, so the shares add up to slightly under 100% even across every area, and an area's cars are a subset of the model's. Pass rate is blank below 30 tests in an area, where a percentage is noise rather than a finding. How this model's pass rate varies by postcode →

What fails a 2020 Mx-5
Everything a tester recorded on this vehicle, grouped into the inspection sections that produced it. The notch on each bar is the national share, so you can see at a glance whether this car is unusual or just ordinary.
A test can record several items, so these percentages do not add up to 100%. The exact strings, with prices, are in the full DVSA record at the bottom of this page.
Before your test
Three checks worth doing on a 2020 Mx-5
These are not generic tips — they are the faults recorded most often on this exact model, rewritten as things you can check yourself. All three take about ten minutes and cost nothing.
-
Check the windscreen 1.1% of tests
“windscreen damaged”
Check the driver’s side of the screen within the swept area for chips and cracks; anything larger than 10mm in the driver’s central view is a fail. Most chips can be resin-repaired for far less than a new screen.
-
Check the brakes 0.6% of tests
“brake pads less than 1.5 mm thick”
Look through the spokes of each wheel at the pad — less than 3mm of friction material, or a lip on the disc edge, is the usual failure. Check the handbrake holds on a slope with a few clicks, not at the top of its travel.
-
Check the lights 0.6% of tests
“headlamp aim too high”
Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
What it costs to get a 2020 Mx-5 through its MOT
Across the 10 items that are recorded most often on this model, the average repair comes to £35–£95 — and 32% of those repairs are parts that cost under £30.

What testers noted without failing the car
Advisories are the early warnings — the same parts a year or two before they fail. Reading them is how you tell a car that has been maintained from one that has been patched.
| Recorded item | Severity | Tests | Est. cost |
|---|---|---|---|
| Brake discs in such a condition that it is seriously weakened Brakes | Advisory | 9.5% | £45–110 |
| Tread depth below requirements of 1.6mm Tyres | Advisory | 5.7% | £45–95 |
| Has a tear, caused by separation or partial failure of its structure Tyres | Advisory | 5.1% | £45–95 |
| Brake pads less than 1.5 mm thick Brakes | Advisory | 4.3% | £18–45 |
| Pins and bushes pin or bush excessively worn Suspension | Advisory | 2.8% | £40–150 |
