SEAT Tarraco — MOT statistics 2024

The SEAT Tarraco failed 12.93% of 1,663 first MOT attempts in 2024 ("first-time", excluding retests). Adjusted for the age of the fleet, its initial-failure ratio is 102.3 (100 = expected for its age profile). This car is too close to call — statistically indistinguishable from normal for its age. Small sample — treat with care.

Age-adjusted peer: Seat Arona (index 102.2) — the two published results are 0.1 index points apart.

SEAT Tarraco common problems: what actually fails the MOT

Tyres stand out at 8.2 per 100 tests, against 5.7 per 100 tests across UK vehicles of the same ages.

Tyres, brakes and suspension: SEAT Tarraco against cars of the same age

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 2,408 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 5.7 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 SEAT Tarraco 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.

How does the SEAT Tarraco perform as it gets older?

The Tarraco at age 4 is close to the reference at 13.4%, against 13.1% for all vehicles of the same age.

Does the month of a SEAT Tarraco MOT matter?

Jan is highest at 16.7%; Dec is lowest at 10.3% — the gap is 6.4 percentage points.

higher = larger sharecompare shares in percentage points

Chart scale: 9%–33%.

bars: SEAT Tarraco · dashed: all class-4 cars

Takeaway: the spread between best and worst month is 6.4 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.

SEAT Tarraco average mileage by age

At age 4, the middle half of Tarracos runs from 24,307 miles to 42,026 miles, against 32,907 miles as the median.

Does high mileage mean more SEAT Tarraco 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, 11.8% of those with under 40,000 miles failed first time versus 16.2% of those with 40,000–70,000 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 4-year-old Tarraco has ~32,907 miles on the clock. Much more — ask why; much less — check for gaps in the MOT history.

Where in Britain the SEAT Tarraco fails its MOT most

Too few tests in any single postcode area to name one, so this is the wider picture across 2,409 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.

SEAT Tarraco 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.

higher = larger sharecompare shares in percentage points

By age 4, only about 100% as many cars of this family present for MOT as at ages 4–6 (reference n≈664); survivors still fail at 13.4% vs 13.4% at age 4. Older cars that still appear are a selected subset — weaker ones have already left.

How many years is a SEAT Tarraco likely to last?

estimateObserved only until age 4. The curve does not run five years past the stated age with the share still tested under 50%, so no 'years left' number is given.

SEAT Tarraco faults that come together

Defects in «Tyres» and «Visibility» were seen together in 16 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).

SEAT Tarraco MOT repair costs

The MOT-failure repair budget per test runs from £15.99 to £30.38, 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 £16 to £30, 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.

SEAT Tarraco running costs for a fleet

Vehicles failing at age 4 are close to the reference at 13.0%, against 13.0% at age 3, tested in the same year.

higher = larger sharecompare shares in percentage points

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.

SEAT Tarraco rust problems: where they corrode

Salt-belt exposure is well below the reference at 33rd percentile, against 50th percentile as the middle of published models.

higher = larger sharecompare shares in percentage points

This SEAT Tarraco has too few tests to judge for corrosion once age is held constant, and its owners live in areas that are about typical 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 SEAT Tarraco?

Tyres after a passed at age 3-5 are highest at 7.6%; Visibility after a passed at age <3 is lowest at 2.4% — the gap is 5.2 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.

SEAT Tarraco ownership: what six years of MOTs show

Odometer anomalies stand out at 0.0%.

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 0.142 failures per 10,000 miles, on a median of 8,142 miles a year across 744 chains. This is the number to compare between models — an annual rate quietly rewards cars that barely leave the drive.

Odometer anomalies: 0% of 746 chains show a reading lower than the previous test, with a median drop of 0 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.

SEAT Tarraco MOT: quick answers

SEAT Tarraco MOT Risk Index is close to the reference at 102.3, 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 SEAT Tarraco first-time MOT pass rate?

87.07% of first attempts passed in 2024 (1,663 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 12.93% figure is the first-time initial failure rate, using 1,663 primary tests as the denominator (first-time, excluding retests). The age-adjusted MOT initial-failure ratio 102.3 is shown separately because raw rates compare fleet age as well as cars.
