The 2018 Mazda Mx-5 MOT pass rate is 93.7% of its MOT tests — 5.8 points ahead of what its age and mileage predict. Brakes is the biggest single reason it fails, at 37.1% of what testers record.
Expert verdict
Brakes make up 37.1% of everything recorded on the 2018 Mazda Mx-5, against 20.9% nationally — 16.2 points above. Have the discs and pads measured rather than glanced at, and ask whether the handbrake holds on a slope.

Cars of this age and mileage average 87.9%, so this figure is 5.8 points ahead of what its age and mileage predict. On a first attempt, before any retests, the figure drops to 93.3%. The median 2018 Mazda Mx-5 in this dataset had covered 24,084 mi.
Pass rates also shift with the test month: tests recorded October–March passed 94.0% of the time, April–September 93.4%.
The single most recorded failure item is "Wipers blade defective", noted on 1.77% of tests.
Figures count every completed test on this vehicle-year in the dataset, including retests. See methodology for the exact definition.

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 →

Regions come from the postcode area recorded at the test station. Areas on region borders are assigned to the region with the majority of their population.
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
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 wipers and washers 1.8% of tests
“wipers blade defective”
Run the wipers with the screen wet: they should clear it in one sweep without smearing or juddering. Top the washer bottle up and check both jets hit the screen.
Check the windscreen 1.4% 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 1.2% 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.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
Across the 10 items that are recorded most often on this model, the average repair comes to £25–£64 — and 53% of those repairs are parts that cost under £30.
Estimates from typical UK parts prices, weighted by how often each item appears in 13,140 MOT tests on this vehicle. They exclude diagnostics, retest fees and garage labour where the part is a DIY fit, and they are not figures from the DVSA dataset. Older and higher-mileage examples cost more than the average.

23 model years on record, from 2000 to 2022. Across them the pass rate runs from 73.2% to 97.2% — a spread of 24 points. The bar under each year is the item that failed it most often.
Colour is the pass rate on a fixed scale, so a block means the same thing on any model. Each year links to its own page with the full fault breakdown.
The raw pass rate mostly measures age. The year comparison adds the like-for-like figure, the mileage bands and the repair bill.
Closest pass rates among 2018 cars with at least 2,000 tests, so a small sample cannot flatter itself into the list. See the full rankings: best and worst MOT pass rates.

Severity is as recorded: Major and Dangerous fail the test outright; Minor and Advisory do not. Costs are estimates from typical UK parts prices — see how they are built.
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.

93.7% of the 13,140 2018 Mazda Mx-5 tests in this dataset passed, against a national average of 87.9% for cars first used in 2018. First-attempt pass rate: 93.3%.
The three most recorded items are wipers blade defective (1.77%), windscreen damaged but not adversely affecting driver's view (1.36%), brake pads less than 1.5 mm thick (1.17%). Percentages are the share of tests on this vehicle that recorded the item.
Yes. Cars under 30,000 miles passed 95.5% of the time, falling to 66.7% for those over 120,000 miles. The median 2018 Mazda Mx-5 in this dataset had covered 24,084 mi.
Tests recorded in the winter months (October–March) passed 94.0% of the time; summer months (April–September) passed 93.4%. Brakes, tyres and lights are tested harder in bad weather, but the difference is small on most models.
