The 2010 Mazda Demio MOT pass rate is 77.3% of its MOT tests — 2.6 points ahead of what its age and mileage predict. Lamps & electrics is the biggest single reason it fails, at 26.9% of what testers record.
Expert verdict
Lamps & electrics make up 26.9% of everything recorded on the 2010 Mazda Demio, against 12.2% nationally — 14.7 points above. Walk round the car with the lights on before the test: bulbs, indicators and number-plate lamps are the cheapest failures to prevent and among the most common.

Cars of this age and mileage average 74.7%, so this figure is 2.6 points ahead of what its age and mileage predict. On a first attempt, before any retests, the figure drops to 71.4%. The median 2010 Mazda Demio in this dataset had covered 48,476 mi.
The single most recorded failure item is "Headlamp lens slightly defective", noted on 6.82% of tests.
Figures count every completed test on this vehicle-year in the dataset, including retests. See methodology for the exact definition.

Pass rate by odometer reading. Bar lengths start at 58% so small gaps stay visible.
| Region | Tests | Pass rate |
|---|---|---|

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 lights 6.8% of tests
“headlamp lens slightly defective”
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.
Check the suspension joints 4.5% of tests
“ball joint dust cover no longer prevents the ingress of dirt”
With the car parked on level ground, rock the top of each front wheel in and out while someone watches the suspension arm. Clunks, or rubber boots split and greasy, are what testers record here.
Check the wipers and washers 4.5% of tests
“wipers does not clear the windscreen effectively”
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.
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 £9–£28 — and 74% of those repairs are parts that cost under £30.
Estimates from typical UK parts prices, weighted by how often each item appears in 88 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.

7 model years on record, from 2000 to 2010. Across them the pass rate runs from 66.8% to 79.2% — a spread of 12.4 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 2010 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.
Shares of the 170 individual items recorded on this vehicle, and the same share across all cars nationally. A single test can record several items, so a row is not a percentage of tests.

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.

|---|---|---|---|
| Tread depth below requirements of 1.6mm Tyres | Advisory | 20.4% | £45–95 |
