Toyota Noah — MOT statistics 2024

The Toyota Noah failed 16.56% of 779 first MOT attempts in 2024 ("first-time", excluding retests). Adjusted for the age of the fleet, its initial-failure ratio is 65.1 (100 = expected for its age profile). This car fails its MOT about 35% less often than expected for its age. Small sample — treat with care.

Age-adjusted peer: Lexus IS (index 65.1) — the two published results are 0.0 index points apart.

Toyota Noah common problems: what actually fails the MOT

Lamps, reflectors and electrical equipment stand out at 28.5 per 100 tests, against 17.2 per 100 tests across UK vehicles of the same ages.

Toyota Noah MOT advisories: what gets flagged

Tyres are highest at 25.3 per 100 tests; Emissions & leaks are lowest at 3.2 per 100 tests — the gap is 22.1 per 100 tests.

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.

A failed test raises next year's chance of failing again by 7.9 percentage points. The failure most likely to come back is lamps, reflectors and electrical equipment — 27.8% 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 2,577 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.

Mileage matters here: matching on how much these are driven moves the figure by 5.9 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 Toyota Noah 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.

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.

Does the month of a Toyota Noah MOT matter?

Jan is highest at 28.6%; Dec is lowest at 18.2% — the gap is 10.4 percentage points.

higher = larger sharecompare shares in percentage points

Chart scale: 17%–33%.

bars: Toyota Noah · dashed: all class-4 cars

Takeaway: the spread between best and worst month is 10.4 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 Noah average mileage by age

At age 8, the middle half of Noahs runs from 52,891 miles to 111,613 miles, against 76,311 miles as the median.

Does high mileage mean more Toyota Noah MOT failures at the same age?

Within the same age group, split by odometer (2024 MOTs), so this separates wear from age: at ages 6–9, 4.3% of those with under 40,000 miles failed first time versus 18.2% of those with 100,000–140,000 miles.No clear mileage gap inside this age group, among cars still being tested.

line: median · band: middle half of the fleet (p25–p75)

A typical 8-year-old Noah has ~76,311 miles on the clock. Much more — ask why; much less — check for gaps in the MOT history.

Where in Britain the Toyota Noah fails its MOT most

Too few tests in any single postcode area to name one, so this is the wider picture across 2,646 tests, 2019-2024.

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 Noah survival: which cars are still on the road

By age 18 is well below the reference at 23.5%, against 100.0% at the ages 4–6 reference level.

higher = larger sharecompare shares in percentage points

Chart axes: car age, years · survival vs ages 4–6 · scale 0–105%.

By age 18, only about 24% as many cars of this family present for MOT as at ages 4–6 (reference n≈221); survivors still fail at 38.5% vs 16.6% at age 4. Older cars that still appear are a selected subset — weaker ones have already left.

How many miles does a Toyota Noah last?

100,000+ miles stands out at 38.9%.

higher = larger sharecompare shares in percentage points

Of 2,641 tests of this family with a usable odometer in 2024, 38.9% had reached 100k miles. This is a cross-section of cars still presenting for MOT, not a full birth cohort.

How many years is a Toyota Noah likely to last?

Bought at age 10 is highest at 8.7 years; Bought at age 15 is lowest at 2.5 years — the gap is 6.2 years.

bigger number = longer remaining lifeyears on the observed survival curve

estimateEstimate only — not a warranty: a typical 10-year-old example of this family has about 8.7 expected years of further MOT-present life on the survival curve, observed only until age 18. Derived from how many cars of each age still appear for test, not from a longitudinal panel.

Toyota Noah faults that come together

Lamps & electrical + Emissions & leaks stand out at 3.96×, against 1.00× if the faults were independent.

above 1.0× = more than expectedbelow 1.0× = less

Defects in «Lamps, reflectors and electrical equipment» and «Noise, emissions and leaks» appear together 3.96× more often than chance (28 co-occurrences in the same test; 55 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).

Is low mileage better for a Toyota Noah?

Cars driven under 5,000 miles a year is well below the reference at 11.3%, against 26.0% for cars driven 8,000–12,000 miles a year.

higher = larger sharecompare shares in percentage points

At matched ages 5–14, cars averaging under 5k miles/year fail at 11.3% vs 26.0% for 8–12k miles/year — 14.8 pp lower (n_low=62, n_normal=100). In this family low annual use is associated with fewer MOT fails, not more — the ‘garage queen’ penalty is not visible in overall fail rates.

Toyota Noah MOT repair costs

The MOT-failure repair budget per test runs from £83.40 to £158.46, against £54.85 for the test itself.

bigger number = costs morepounds per test, MOT-failing faults only

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 £83 to £158, 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.

Toyota Noah rust problems: where they corrode

Salt-belt exposure is well below the reference at 12th percentile, against 50th percentile as the middle of published models.

higher = larger sharecompare shares in percentage points

This Toyota Noah has too few tests to judge for corrosion once age is held constant, and its owners live in areas that are gentler 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 Noah?

Lamps, reflectors and electrical equipment after a failure at age 12-14 are highest at 32.4%; Visibility after a passed at age 3-5 is lowest at 2.3% — the gap is 30.1 percentage points.

higher = more likelypercentage is the observed transition probability

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 Noah ownership: what six years of MOTs show

Odometer anomalies stand out at 34.8%.

higher = larger sharecompare shares in percentage points

Per mile driven, not per year. Dividing failures by the miles that actually went onto the odometers between consecutive tests gives 0.306 failures per 10,000 miles, on a median of 6,869 miles a year across 532 chains. This is the number to compare between models — an annual rate quietly rewards cars that barely leave the drive.

Odometer anomalies: 34.783% of 552 chains show a reading lower than the previous test, with a median drop of 39,158 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.

Toyota Noah MOT: quick answers

Toyota Noah MOT Risk Index is well below the reference at 65.1, 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 Noah first-time MOT pass rate?

83.44% of first attempts passed in 2024 (779 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 16.56% figure is the first-time initial failure rate, using 779 primary tests as the denominator (first-time, excluding retests). The age-adjusted MOT initial-failure ratio 65.1 is shown separately because raw rates compare fleet age as well as cars.
