Mazda 5 — MOT statistics 2024
The Mazda 5 failed 47.78% of 10,518 first MOT attempts in 2024 ("first-time", excluding retests). Adjusted for the age of the fleet, its initial-failure ratio is 122.4 (100 = expected for its age profile). This car fails its MOT about 22% more often than expected for its age.
Age-adjusted peer: Chevrolet Spark (index 122.7) — the two published results are 0.3 index points apart.

family vs national — matched to UK vehicles of the same ages — top component groups, per 100 tests. Legend: This family · National avg. Combined labels: family / national average. A gap here reflects how these vehicles are driven, used and maintained as well as how they were built — an MOT defect is a test outcome, not a breakdown.
Component-group comparison table
Each ratio carries a 95% interval. With 6 groups compared here, roughly one apparent difference in twenty is chance alone.

If a car like this fails, does it fail again?
A failure rate does not say whether a failure is a one-off or the start of something. This follows the same vehicles into their next ordinary MOT a year later — retests after a repair are excluded, because they follow a failure by definition. 2019-2024.
| After this year's test | Fails next year | Vehicles followed |
|---|---|---|
| It failed | 44.6% | 7,582 |
| It passed | 40.5% | 35,696 |
A failed test raises next year's chance of failing again by 4.1 percentage points. The failure most likely to come back is steering — 44.3% of those vehicles fail again next year. Some of this is the vehicle and some is the owner: a car that was let go once tends to be let go again. One caveat: a car that fails may be sold or scrapped rather than tested again, so these figures describe the vehicles that came back.
Adjusted for how much these are actually driven
The headline index adjusts for the fleet's age. Wear, though, follows mileage: a three-year-old taxi and a three-year-old garage queen sit in the same age band. These two rows compare every car with vehicles of the same age, and then with vehicles of the same age and the same annual mileage, 2019-2024, on 91,571 tests. Both stand on the six-year corpus so they are measured on identical data — compare them with each other, not with the headline index above, which is measured on 2024 alone.
| Standardised for | Index | Reading |
|---|---|---|
| Age only | 126.7 | fails more often than expected |
| Age and annual mileage | 121.6 | fails more often than vehicles driven as much |
| Share doing under 3,000 miles a year | 1.2% | a normal spread of use |
Mileage matters here: matching on how much these are driven moves the figure by 5.1 points — this fleet works harder than the vehicles it is measured against, so the age-only view penalises it — but it does not change which side of normal the car sits on. One limit to keep in mind: mileage is partly a result of how often a car breaks down — one that spends weeks in the workshop covers fewer miles — so the mileage-matched figure can understate a real weakness. Tests with no usable odometer reading are left out of it.
How the Mazda 5 compares with cars of its own age and size
Not against the whole fleet — against cars of the same size class tested at the same age, 2019-2024.

Is a Mazda 5 ULEZ compliant?
The share of classifiable 2024 Mazda 5 MOT tests likely ULEZ compliant by first-registration date is 72.5%.
Based on 10,459 classifiable initial MOT tests. This describes the tested fleet, not a specific car. MOT data do not record Euro class, so likely compliance is inferred from fuel and first-registration date. For the only authoritative answer, check the registration with TfL's official ULEZ checker.

Takeaway: the spread between best and worst month is 3.5 percentage points — noticeable seasonality. Seasonality partly reflects registration-date clustering, not weather.
Before reading the shape: most of it is not about cars. Britain changes its registration plates twice a year, and 18.9% of these cars were first registered in March with another17.1% in September — 36% in two months against the 17% an even spread would give. An MOT falls due three years after first registration, so the buying calendar becomes the testing calendar. That shapes how many cars are tested each month — not how often they fail: the busiest months here are not the worst ones, so read the failure line on its own and the volume behind it separately.

Does high mileage mean more Mazda 5 MOT failures at the same age?
Within the same age group, split by odometer (2024 MOTs), so this separates wear from age: at ages 15+, 40.5% of those with 40,000–70,000 miles failed first time versus 59.1% of those with over 140,000 miles.Inside this age group, higher mileage goes with more failures.

Why do areas differ?
For each external factor we correlate the area fail rate with the factor across postcode areas that have ≥800 tests of this family, then compare the bottom vs top fifth (quintile) of the factor. Correlation, not causation — factors travel together (the north is colder and often poorer; urban areas are denser and less salted). Road surface condition is joined now, for the 91 English areas the DfT publishes, and it explains nothing: the correlation with suspension failures is −0.01 and with body and structure failures 0.07. Potholes wreck wheels and tyres between tests, but by the time a car reaches the bay the road it drives on leaves no measurable trace.
In areas with the highest mot centre density this model fails 12.3 pp more often than in the lowest fifth (r=0.75, n=49 areas with ≥800 tests).
In areas with the highest terrain gradient this model fails 9.8 pp more often than in the lowest fifth (r=0.60, n=32 areas with ≥800 tests).
In areas with the highest urban share this model fails 10.2 pp less often than in the lowest fifth (r=-0.55, n=49 areas with ≥800 tests).
| Factor | Low Q | High Q | Gap | Correlation |
|---|---|---|---|---|
| MOT centre density | 40.6% | 52.9% | +12.3 pp | r=0.75 |
| Terrain gradient | 45.5% | 55.3% | +9.8 pp | r=0.60 |
| Urban share | 51.3% | 41.1% | -10.2 pp | r=-0.55 |
Factors that only mean something combined
Some conditions are useless on their own and informative multiplied together. Frost days alone say little — Britain barely freezes. Salt tonnage alone says little — it tracks frost. Distance to the sea alone says little. Multiply the first two and divide by the third and you get an index of how hard an area attacks a car's underside, and it lines up with the corrosion defects we actually record. We built five such combinations and tested each against our own data. Three survived; two did not, and the failures are listed here on purpose — a proxy that was never checked is decoration. One survivor only survived on the second attempt: built from a crude stand-in for street parking it failed outright, and rebuilt from the census — terraced streets carrying more cars than they have driveways — it works, and carries information the salt index does not.
| Composite | Built from | Tested against | r | Verdict |
|---|---|---|---|---|
| Underbody corrosion | frost days × salt load ÷ (distance to coast + 1) | share of tests with a corrosion defect | +0.42 | holds (116 areas) |
| Tyre wear | rain days × annual miles ÷ age at first tyre advisory | share of tests failing on tyres | +0.45 | holds (116 areas) |
| Overnight corrosion | terraced housing × cars per household × frost days | share with a corrosion defect | +0.41 | holds (102 areas) — and adds signal beyond the first index |
| Deferred maintenance | deprivation × advisory-to-failure conversion ÷ labour rate | cars repeating the same advisory | −0.26 | fails (118 areas) |
| Powertrain stress | engine capacity ÷ kerb weight | suspension, brake and emissions failures | −0.16 | fails (22 models) |
The deprivation result is the one worth dwelling on. The intuition that poorer areas defer repairs is strong enough that most people treat it as established. We tested it twice — once on raw failure rates (r = 0.04) and again, more fairly, on whether an advisory turns into a failure — and it did not hold any of the three times we tried it — on raw failure rates, on advisory-to-failure conversion, and again with deprivation measured properly inside each nation rather than England alone. We are closing it. What does predict local failure rates is the density of test centres, which is a statement about testing, not about cars.

Every dot is a postcode area — size = how many were tested there, colour = share failing. These figures are not age-adjusted: coastal and rural areas often run older fleets and salted roads, so higher raw fail rates do not automatically mean a worse local stock of this model.

By age 18, only about 63% as many cars of this family present for MOT as at ages 4–6 (reference n≈1,413); survivors still fail at 55.2% vs 21.1% at age 4. Older cars that still appear are a selected subset — weaker ones have already left.
How many miles does a Mazda 5 last?
100,000+ miles is highest at 42.5%; 150,000+ miles is lowest at 5.3% — the gap is 37.2 percentage points.

|---|---|---|
| 100,000+ miles | 38,982 | 42.54% |
| 150,000+ miles | 4,891 | 5.34% |
Of 91,628 tests of this family with a usable odometer in 2024, 42.5% had reached 100k miles, 5.3% had reached 150k miles. This is a cross-section of cars still presenting for MOT, not a full birth cohort.
How many years is a Mazda 5 likely to last?
Bought at age 5 is highest at 14.0 years; Bought at age 15 is lowest at 3.1 years — the gap is 10.9 years.

The best build year here is 2012 and the weakest is 2007. Comparing build years sounds simple and is not: within a single year of testing, a car's build year and its age are the same number, so a naive comparison of years is a comparison of ages wearing a disguise. Each year below is measured against the same model at the same age in other cohorts, across six years of testing — 4 of 11 years come out distinguishable from their own model's age norm.
Two limits worth knowing before you act on this. Age, test year and build year are locked together by arithmetic, so the test-year effect is taken from the observed national failure level of each year rather than estimated — it is an adjustment, not a solution.
Mazda 5 MOT repair costs
The MOT-failure repair budget per test runs from £190.39 to £361.74, against £54.85 for the test itself.
bigger number = costs morepounds per test, MOT-failing faults only
| Component | Fails per 100 tests | Typical repair | Its price | Contribution |
|---|---|---|---|---|
| Suspension | 46.1 (nat. 15.36) | Suspension coil spring (single corner) | £180 | £82.98 |
| Lamps, reflectors and electrical equipment | 31.1 (nat. 18.09) | Battery replacement (standard 12V lead-acid) | £140 | £43.54 |
| Noise, emissions and leaks | 12.6 (nat. 3.67) | Exhaust rear silencer | £200 | £25.20 |
| Brakes | 16.3 (nat. 11.25) | Front brake pads (parts + labour, typical hatchback) | £150 | £24.45 |
| Tyres | 15.8 (nat. 8.7) | Tyre (single mid-range 16" fitted) | £90 | £14.22 |
Multiply how often each component fails on this model by what that repair usually costs, and you get the amount an owner should expect to budget per test for MOT-failing faults only — roughly £190 to £362, on top of the test fee itself. It is a budgeting figure, not a quote: the spread between a set of pads and a set of discs is most of the range.
Prices are modal quotes from a hand-kept catalogue of published UK garage guides — we do not scrape the booking sites, their terms forbid it, so this list is short and updated by hand with a source and date against each line. Each line prices one typical repair in that group, not a full remedy, and only groups our catalogue actually covers are counted. The contrast worth noticing is the second card: the legal maximum for the test has been £54.85 since 2010, while the repairs it uncovers have followed inflation the whole time.
For scale from a different direction: Warrantywise, which sees used-car warranty claims rather than test failures, puts the average claim at £2,052 across the ten highest-claim models it ranks and £539 for Honda, the lowest-claim make in its index (Warrantywise index 2026, 1.6 million claims, cars aged 3–15). Those sit an order of magnitude above the figures in this table, and the gap is the point: a warranty claim is a gearbox or an engine, which almost never fails an MOT, while the faults that do fail one are corrosion, lamps and tyres, which no warranty pays for. The two numbers answer different questions and neither replaces the other.

No single year stands out as the point where this model starts costing more: the year-to-year steps in its failure rate are too small or rest on too few tests to name one (D1 rule: a step is named only with at least 2,000 tests on both sides and a jump above 3 percentage points).
Repair spend uses the same modal prices as the section above, so it inherits the same limits: one typical repair per component group, not a full remedy. Downtime is the gap between the failed test and the passed re-test, which is the window a vehicle is legally off the road.
Mazda 5 rust problems: where they corrode
Age-standardised corrosion susceptibility stands out at 1.68×, against 1.00× for the national age-standardised rate.
above 1.0× = rusts more than averagebelow 1.0× = rusts less
This Mazda 5 fails on corrosion far more often than average once age is held constant, and its owners live in areas that are gentler than most for the models we publish. Those two point in opposite directions, which is the informative case: it rusts more than average despite living in gentler places, so the cause is the car, not the postcode.
Corrosion is the one failure mode that is as much about geography as about the car. We keep the two apart on purpose: a model can look rusty simply because it is popular in Scotland, and a model can look clean simply because it is bought in Surrey. Blending them into a single score would hide which of the two is doing the work.
Exposure is this model's tests weighted by an area corrosion index built from frost days, salt load and distance to the coast — the composite validated at r = 0.42 against corrosion defects we actually record. It is published as a rank, not a raw score, because every mainstream model skews towards low-corrosion areas for the simple reason that most of Britain's cars are in the south. Susceptibility is standardised to the national age profile, so an old fleet does not get labelled a rusty model.

| Road wheels | 0.9% | 11.9 months | 4,560 | 670 |
This is the question an advisory note actually raises, and it needs six years of test history to answer. We followed the same vehicles from one MOT to the next across 2019–2024 and measured how often a component that was merely advised came back as a genuine failure at the next test.
Read it as a budgeting horizon, not a prophecy: the most likely component above turns into a failure for about 33 in 100 cars, and the median gap is 12 months and roughly 5,946 miles. The rest were repaired, sold, scrapped, or simply held. Rows with fewer than 500 tracked advisories are not shown.
What will fail next on a Mazda 5?

The same chains, cut differently: given a car's age and how its last test went, which component most often causes trouble at the following one.
The pattern that repeats across every family: a failure at one test roughly doubles the chance of a failure on the same component at the next one, and an advisory sits about half-way between a clean pass and a failure. Age bands in years; probabilities are per car, not per defect item.
Mazda 5 ownership: what six years of MOTs show
The ten-day re-test pass rate is highest at 59.4%; The later re-test pass rate is lowest at 3.5% — the gap is 55.9 percentage points.
higher = larger sharecompare shares in percentage points
Failing is usually a same-week event, not a disaster. Of 32,334 failures followed through to their re-test, 37.17% were repaired and passed the same day and 59.36% within ten days; the median gap is 1 day. 99,920 defect items were cleared in the process.
Per mile driven, not per year. Dividing failures by the miles that actually went onto the odometers between consecutive tests gives 0.731 failures per 10,000 miles, on a median of 5,587 miles a year across 18,197 chains. This is the number to compare between models — an annual rate quietly rewards cars that barely leave the drive.
Two populations hide inside one model. 15.57% of these cars strung together three or more tests with nothing recorded at all, while 52.87% carried the same advisory three times or more — the same fault, noted, ignored, noted again. When you buy used you are buying one of those two histories, and the MOT record shows which.
Odometer anomalies: 0.862% of 18,210 chains show a reading lower than the previous test, with a median drop of 12,109 miles. We call this an anomaly and not fraud on purpose — instrument swaps, imports, unit mix-ups and keying errors all land in the same bucket. Obvious typos (drops under 100 miles or over 90% of the reading) are already excluded.

DVSA lists 13 safety recall campaigns for the Mazda 5, covering roughly 321,741 vehicles in total. A recall is the manufacturer fixing a fault for free, so an open recall on your car costs nothing to clear.
Counter-intuitive, and measured on our own data: across the 25 families published here, more recalls go with a lower MOT Risk Index (r = −0.52). Heavily recalled models are not worse cars in the test bay — an active manufacturer removes the fault before it becomes an MOT failure.

Mazda 5 inspection results in other countries
Finland Katsastus stands out at 51.3%, against 26.3% nationally.
higher = larger sharecompare shares in percentage points
| Country | Test | This model fails | National average | Position | Sample |
|---|---|---|---|---|---|
| United Kingdom | MOT (class 4) | 47.78% | 26.01% | +21.8 pp | 10,518 |
| Netherlands | APK | 60.8% | 50.8% | +10 pp | 6,155 |
| Finland | Katsastus | 51.3% | 26.3% | +25 pp | 1,379 |
| Norway | PKK | 48.6% | 33.7% | +14.9 pp | 1,002 |
The verdict is consistent across every regime where the difference is clear, which is the strongest form this comparison takes: independent inspectorates, different rulebooks, same direction of travel.
| Code | Fault | Recorded | Type |
|---|---|---|---|
205 | Tyre with insufficient tread | 1,117 | failure |
210 | Tyre pressure not at the correct value | 1,077 | failure |
115 | Exhaust not gas-tight or venting unsafely | 621 | failure |
584 | Sidelight not working properly | 612 | failure |
497 | Number-plate light not working or missing | 607 | failure |
516 | Dipped headlight incorrectly aimed | 443 | failure |
AC1 | Tyre down to 1.6–2.5 mm of tread | 436 | advisory |
391 | Wipers leave insufficient visibility | 422 | failure |
Worth dwelling on how mundane the top of that list is: tyre pressure, tread depth, headlight aim. The Dutch APK records 1.664 defects per inspection against a much higher national failure rate than Britain's, and the reason is not that Dutch cars are worse — it is that the two regimes draw the line between "note it" and "fail it" in different places. Codes are the RDW's own; the English wording here is our translation of the Dutch original.
Britain is not the only country that inspects every car every year, and the Mazda 5 is on the road in all of them. Each national regime writes its own rules, so the pass rates below are not comparable to each other — what does travel across a border is whether a model sits above or below its own country's average.

Mazda 5 MOT: quick answers
Mazda 5 MOT Risk Index stands out at 122.4, against 100 for a car with the same age profile.
below 100 is betterabove 100 is worse100 = normal for this model at that age
- What is the Mazda 5 first-time MOT pass rate?
- 52.22% of first attempts passed in 2024 (10,518 tests). This is the first-time figure: retests after repair are excluded. Basis: first-time, excluding retests.
- Why does this number differ from other sites?
- Other sites often report a pass rate that includes retests or counts all attempts. Our 47.78% figure is the first-time initial failure rate, using 10,518 primary tests as the denominator (first-time, excluding retests). The age-adjusted MOT initial-failure ratio 122.4 is shown separately because raw rates compare fleet age as well as cars.

Data details & how to cite
Scope: class-4 vehicles (cars), initial tests only, outcomes pass / fail / fixed-on-the-spot at the station (PRS counts towards the failure rate — the defect was present at arrival). Index = observed initial failures ÷ failures expected for this fleet's exact age profile, ×100; margin of error is a 95% confidence interval. Covers ALL generations together — a 3-year-old and a 15-year-old are very different cars; a generation split is on the roadmap.
