Toyota GR Yaris — MOT statistics 2024
The Toyota GR Yaris failed 6.78% of 3,214 first MOT attempts in 2024 ("first-time", excluding retests). Adjusted for the age of the fleet, its initial-failure ratio is 54.7 (100 = expected for its age profile). This car fails its MOT about 45% less often than expected for its age. Small sample — treat with care.
Age-adjusted peer: Mercedes-Benz CL (index 54.8) — the two published results are 0.1 index points apart.
Toyota GR Yaris common problems: what actually fails the MOT
Visibility is well below the reference at 1.9 per 100 tests, against 4.2 per 100 tests across UK vehicles of the same ages.

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 2 groups compared here, roughly one apparent difference in twenty is chance alone, and 1 of these is already inside an interval that includes 1.00×.

Tyres, brakes and suspension: Toyota GR Yaris against cars of the same age
| Age | Part | Toyota GR Yaris | Same age, petrol and diesel | Difference |
|---|---|---|---|---|
| 3 years | Tyres | 3.38 | 4.17 | -0.79 |
| 3 years | Brakes | 0.51 | 1.77 | -1.26 |
| 3 years | Suspension | 0.22 | 0.63 | -0.41 |
Failing items per 100 initial tests, 2019-2024. The comparison group is every petrol or diesel car tested at the same age, so weight and drivetrain show up rather than fleet age.
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 3,436 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 | 55.1 | fails less often than expected |
| Age and annual mileage | 76.1 | fails less often than vehicles driven as much |
| Share doing under 3,000 miles a year | 31.1% | a large low-use population — often second vehicles or cars kept for occasional use |
Split by how much each car is driven. This is a split by annual mileage, not by body type — the MOT record does not say whether a car is a conversion. Within each band the index compares with vehicles of the same age driven as much.
| Miles a year | Tests | Failed first time | Index within band |
|---|---|---|---|
| under 3,000 | 1,068 | 3.3% | 57.3 |
| 3,000–6,000 | 1,395 | 6.1% | 73.5 |
| 6,000–9,000 | 635 | 11.5% | 97.3 |
Mileage matters here: matching on how much these are driven moves the figure by 21.0 points — this fleet is driven less than the vehicles it is measured against, so the age-only view flatters 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 Toyota GR Yaris 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.
| Age | Toyota GR Yaris | Same class, same age | Difference | Tests |
|---|---|---|---|---|
| 3 years | 6.69% | 11.7% | -5.01 pp | 3,140 |
| 4 years | 8.54% | 13.29% | -4.75 pp | 199 |
Raw first-time failure rates within each age, so fleet age cannot flatter either side. A positive difference means this model fails more often than its own class at that age.
How does the Toyota GR Yaris perform as it gets older?

Is a Toyota GR Yaris ULEZ compliant?
The share of classifiable 2024 Toyota GR Yaris MOT tests likely ULEZ compliant by first-registration date is 100.0%.
Based on 3,214 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.

| Dec | 5.93% | 29.33% | -23.4 pp |
Takeaway: the spread between best and worst month is 6.6 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.
Toyota GR Yaris average mileage by age
At age 4, the middle half of GR Yaris models runs from 9,773 miles to 23,012 miles, against 15,663 miles as the median.

Does high mileage mean more Toyota GR Yaris MOT failures at the same age?
Within the same age group, split by odometer (2024 MOTs), so this separates wear from age: at ages 3–5, 6.7% of those with under 40,000 miles failed first time versus 13.8% of those with 40,000–70,000 miles.No clear mileage gap inside this age group, among cars still being tested.

Where in Britain the Toyota GR Yaris fails its MOT most
Too few tests in any single postcode area to name one, so this is the wider picture across 3,436 tests, 2019-2024.
| Part of Britain | % failing | Tests |
|---|---|---|
| Southern England | 8.15% | 1,447 |
| Scotland | 6.8% | 294 |
| Midlands | 5.99% | 985 |
| Northern England | 5.16% | 523 |
| Wales | 4.3% | 186 |
Raw pass/fail rates, not age-adjusted: fleets differ by region. England is split north of Sheffield, between Sheffield and Oxford, and south of it.
Toyota GR Yaris survival: which cars are still on the road
By age 4 is close to the reference at 100.0%, against 100.0% at the ages 4–6 reference level.

Toyota GR Yaris faults that come together
| Group A | Group B | Together | Lift |
|---|---|---|---|
| Tyres | Visibility | 8 | too few (rough estimate) |
| Noise, emissions and leaks | Tyres | 7 | too few (rough estimate) |
| Body, chassis, structure | Noise, emissions and leaks | 5 | too few (rough estimate) |
Defects in «Tyres» and «Visibility» were seen together in 8 tests (45 pairs compared).
Lift = how many times more often both groups appear on the same test than if independent. A pair is listed from 5 tests with both faults; the lift is shown from 20, and called above chance only when its 95% interval excludes 1 (see rough estimates).
Toyota GR Yaris running costs for a fleet

Failure rate and typical odometer by age
| Age | Fails | Median odometer | Tests | Gap vs age 5 |
|---|---|---|---|---|
| 3 | 6.68% | 12,745 | 2,979 | — |
| 4 | 8.54% | 15,663 | 199 | — |
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.
Toyota GR Yaris rust problems: where they corrode
Salt-belt exposure stands out at 69th percentile, against 50th percentile as the middle of published models.
higher = larger sharecompare shares in percentage points
This Toyota GR Yaris has too few tests to judge for corrosion once age is held constant, and its owners live in areas that are saltier than most for the models we publish.
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.
What will fail next on a Toyota GR Yaris?
Visibility after a passed at age <3 stands out at 2.3%.
higher = more likelypercentage is the observed transition probability
| Age | Last test | Most likely next failures | Cars tracked |
|---|---|---|---|
| <3 | passed | Visibility 2.3% | 219 (rough estimate) |
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.
Toyota GR Yaris MOT: quick answers
Toyota GR Yaris MOT Risk Index is well below the reference at 54.7, 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 Toyota GR Yaris first-time MOT pass rate?
- 93.22% of first attempts passed in 2024 (3,214 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 6.78% figure is the first-time initial failure rate, using 3,214 primary tests as the denominator (first-time, excluding retests). The age-adjusted MOT initial-failure ratio 54.7 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.
