Vauxhall Astra — MOT statistics 2024

The Vauxhall Astra failed 33.71% of 914,157 first MOT attempts in 2024 ("first-time", excluding retests). Adjusted for the age of the fleet, its initial-failure ratio is 109.1 (100 = expected for its age profile). This car fails its MOT about 9% more often than expected for its age.

Age-adjusted peer: Nissan Leaf (index 109.2) — the two published results are 0.1 index points apart.

Does the month of a Vauxhall Astra MOT matter?

higher = larger sharecompare shares in percentage points

Chart scale: 23%–38%.

bars: Vauxhall Astra · dashed: all class-4 cars

Takeaway: the spread between best and worst month is 4.0 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 19.5% of these cars were first registered in March with another17% in September — 37% 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. Peaks here mark when cars are tested, not when they are worse.

Vauxhall Astra average mileage by age

At age 8, the middle half of Astras runs from 47,378 miles to 81,123 miles, against 63,058 miles as the median.

Does high mileage mean more Vauxhall Astra MOT failures?

Same age band (6–14 years), split by odometer — this separates wear from age: 15% of the lowest-mileage cars failed versus 40.2% of the highest.

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 6.0 pp more often than in the lowest fifth (r=0.50, n=114 areas with ≥800 tests).

In areas with the highest urban share this model fails 5.2 pp less often than in the lowest fifth (r=-0.41, n=114 areas with ≥800 tests).

In the most coastal fifth of areas this model fails 4.1 pp more often than in the most inland fifth (r=-0.39, n=114 areas with ≥800 tests).

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 area indicators, each tested against a defect rate we measure

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.

Vauxhall Astra survival: which cars are still on the road

By age 19 stands out at 82.8%, against 100% 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 19, only about 83% as many cars of this family present for MOT as at ages 4–6 (reference n≈26,293); survivors still fail at 48.4% vs 11.1% at age 4. Older cars that still appear are a selected subset — weaker ones have already left. DfT licensed stock is 46% of its 2008 Q4 peak (1,149,218 → 527,414).

How many miles does a Vauxhall Astra last?

100,000+ miles is highest at 34.8%; 200,000+ miles is lowest at 0.9% — the gap is 33.9 percentage points.

higher = larger sharecompare shares in percentage points

Of 911,733 tests of this family with a usable odometer in 2024, 34.8% had already reached 100k miles, 6.7% reached 150k, and 0.9% reached 200k — a cross-section of cars still presenting for MOT, not a full birth cohort.

How many years is a Vauxhall Astra likely to last?

Bought at age 5 is highest at 14.3 years; Bought at age 15 is lowest at 4.3 years — the gap is 10 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 (~78,982 miles median) has about 9.3 expected years of further MOT-present life on the 2024 survival curve. Derived from how many cars of each age still appear for test, not from a longitudinal panel.

Vauxhall Astra faults that come together

Body & structure + Emissions & leaks stand out at 9.36×, against 1× if the faults were independent.

above 1.0× = more than expectedbelow 1.0× = less

Defects in «Body, chassis, structure» and «Noise, emissions and leaks» appear together 9.36× more often than chance (10,907 co-occurrences in the same test; lift≥1.3, n≥300).

Lift = how many times more often both groups appear on the same test than if independent. Thresholds: lift ≥ 1.3, co-occurrences ≥ 300.

Is low mileage better for a Vauxhall Astra?

Cars driven under 5,000 miles a year stands out at 19.1%, against 32.0% 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 19.1% vs 32.0% for 8–12k miles/year — 12.9 pp lower (n_low=96,429, n_normal=225,908). 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. Diesel alone: 18.4% low-use vs 32.2% normal (-13.7 pp).

Vauxhall Astra real MPG against official fuel economy

petrol/electric (2022) real-world fuel use stands out at +317.31%, against 0% for an exact match to the official figure.

higher = larger sharecompare shares in percentage points

Since 2021 every new car in Europe records its own fuel use, and the regulator publishes what those meters say next to the laboratory figure the car was sold on. For this manufacturer the worst gap is 18.4% — diesel cars of 2021 burning 5.83 litres per 100 km against an official 4.93, with CO₂ higher by the same proportion.

This is the manufacturer, not the model. The regulator aggregates by legal manufacturer (OPEL AUTOMOBILE), so these figures are context for the badge rather than a measurement of this particular car — a point we would rather state plainly than let a reader assume otherwise. The gap itself is not a scandal, it is the known distance between a standardised laboratory cycle and real roads, but it is the distance you actually pay for at the pump. The plug-in hybrid rows are not a data error and deserve a sentence of their own: an official figure of 1.36 litres assumes the car spends most of its life on the battery, and the meters say these ones burned 5.52. Owners are not plugging them in, and a plug-in hybrid that is never charged is simply a heavy petrol car.

Which Vauxhall Astra engine is best?

diesel 1.5–1.8 is highest at 107.2; petrol 1.8–2.0 is lowest at 56.5 — the gap is 50.7 points.

below 100 is betterabove 100 is worse100 = normal for this model at that age

Splitting this model by fuel alone hides the thing that actually differs. Within the same badge, the diesel 1.5–1.8 runs at 107.2 against this model's own age norm while the petrol 1.8–2.0 runs at 56.5 — a spread of 50.7 points between two cars that share a name.

Read this one with more care than the rest of the page. Age is held constant, but who buys which engine is not: the largest capacity in a range is often a performance or executive variant that is garaged, cherished and lightly driven, while the smallest is frequently a fleet or entry car worked hard from new. The gap below is real in the test records; how much of it is the engine and how much is the owner, this data cannot separate. Bands under 5,000 tests are not shown.

Best year for a Vauxhall Astra, and the years to avoid

Build year 2014 is highest at 107.2; Build year 2020 is lowest at 80.1 — the gap is 27.1 points.

below 100 is betterabove 100 is worse100 = normal for this model at that age

build year vs the same model at the same age · 100 = as expected

The best build year here is 2020 and the weakest is 2014. 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 — 20 of 23 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. And for cars built before about 2005, a good score says more about which examples survived to be tested than about how that year was built: survivors are self-selected for care.

Vauxhall Astra MOT repair costs

The MOT-failure repair budget per test runs from £146.69 to £278.71, 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 £147 to £279, 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.

Vauxhall Astra running costs for a fleet

Vehicles failing at age 10 stand out at 32%, against 15% at age 5 in the same 100-vehicle fleet.

higher = larger sharecompare shares in percentage points

The number a fleet manager needs is not the failure rate, it is the year the car starts costing more. Between age 8 and 9 the failure rate of this model jumps by 6.69 percentage points — the steepest single step in its life, and the natural planning point for replacement.

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.

Vauxhall Astra rust problems: where they corrode

Age-standardised corrosion susceptibility stands out at 1.24×, against 1× for the national age-standardised rate.

above 1.0× = rusts more than averagebelow 1.0× = rusts less

This Vauxhall Astra fails on corrosion more often than average 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.

Does a Vauxhall Astra advisory become a failure?

Lamps, reflectors and electrical equipment are highest at 30.3%; Seat belts and supplementary restraint systems are lowest at 3.4% — the gap is 26.9 percentage points.

higher = more likelypercentage is the observed transition probability

chance the same component fails at the next MOT, given an advisory now

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 30 in 100 cars, and the median gap is 12.1 months and roughly 4,942 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 Vauxhall Astra?

Lamps, reflectors and electrical equipment after a failure at age 15-19 are highest at 31.6%; Visibility after a passed at age <3 is lowest at 2.0% — the gap is 29.6 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.

Vauxhall Astra ownership: what six years of MOTs show

The ten-day re-test pass rate is highest at 51.4%; The later re-test pass rate is lowest at 2.6% — the gap is 48.8 percentage points.

higher = larger sharecompare shares in percentage points

Failing is usually a same-week event, not a disaster. Of 1,166,555 failures followed through to their re-test, 45.95% were repaired and passed the same day and 51.44% within ten days; the median gap is 1 day. 3,112,333 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 0.545 failures per 10,000 miles, on a median of 5,363 miles a year across 885,518 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. 27.99% of these cars strung together three or more tests with nothing recorded at all, while 38.34% 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: 1.046% of 886,371 chains show a reading lower than the previous test, with a median drop of 23,420 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.

Do Vauxhall Astra recalls reduce MOT failures?

R/2023/031 (Suspension) beyond the comparison fleet stands out at -1.7 pp, against 0 pp for no movement beyond the fleet.

negative = improved beyond the comparison fleetpositive = worsened

A fair test needs a control. Failure rates climb as any fleet ages, so a simple before-and-after around a recall date makes every campaign look useless. Below, each campaign's component is age-standardised and compared against how every other model published here moved on that same component over the same months. The last column is what is left after subtracting the fleet-wide drift.

Negative in the last column means the recalled component improved faster than the rest of the fleet. Across all campaigns we could measure, roughly half clear that bar and half do not — recalls help, but the effect is small at fleet level and inconsistent between campaigns. not causal: no VIN-level link between a car and a campaign, and no evidence the remedy was carried out. Cells with fewer than 500 tests either side are not published. One limit decides how far this goes: the MOT inspects brakes, lights, suspension and structure, so a recall for an airbag inflator or a wiring fire risk leaves no trace here at all. Read this as evidence about recalls whose component the test actually examines — never as a verdict on whether recalls work.

Vauxhall Astra safety recalls and how to check yours

DVSA recall campaigns stand out at 37, against 0.7 campaigns per 10,000 licensed cars after fleet size is accounted for.

bigger number = more recorded casescompare like-for-like scope, not sample size alone

recall campaigns launched per year

DVSA lists 37 safety recall campaigns for the Vauxhall Astra — 0.7 campaigns per 10,000 of these cars licensed in Great Britain, covering roughly 696,444 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.

Vauxhall Astra inspection results in other countries

United Kingdom MOT stands out at 33.7%, against 26.0% nationally.

higher = larger sharecompare shares in percentage points

The verdict is consistent across every regime we can measure, which is the strongest form this comparison takes: independent inspectorates, different rulebooks, same direction of travel.

Useful as a cross-check on the UK defect table above: the categories are named differently, but a component that dominates in both regimes is a genuine weak point of the model rather than an artefact of one country's testing style.

Worth dwelling on how mundane the top of that list is: tyre pressure, tread depth, headlight aim. The Dutch APK records 1.236 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 Vauxhall Astra 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.

Vauxhall Astra MOT: quick answers

Vauxhall Astra MOT Risk Index stands out at 109.1, 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 Vauxhall Astra first-time MOT pass rate?

66.29% of first attempts passed in 2024 (914,157 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 33.71% figure is the first-time initial failure rate, using 914,157 primary tests as the denominator (first-time, excluding retests). The age-adjusted MOT initial-failure ratio 109.1 is shown separately because raw rates compare fleet age as well as cars.
