Chevrolet Kalos — MOT statistics 2024

The Chevrolet Kalos failed 52.96% of 2,430 first MOT attempts in 2024 ("first-time", excluding retests). Adjusted for the age of the fleet, its initial-failure ratio is 122.3 (100 = expected for its age profile). This car fails its MOT about 22% more often than expected for its age. Small sample — treat with care.

Age-adjusted peer: Mazda 5 (index 122.4) — the two published results are 0.1 index points apart.

Chevrolet Kalos common problems: what actually fails the MOT

Brakes stand out at 34.4 per 100 tests, against 20.0 per 100 tests across UK vehicles of the same ages.

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.

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 2.5 percentage points. The failure most likely to come back is lamps, reflectors and electrical equipment — 43.5% 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 28,422 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 16.0 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 Chevrolet Kalos 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 Chevrolet Kalos perform as it gets older?

The Kalos at age 16 stands out at 55.0%, against 43.1% for all vehicles of the same age.

higher = larger sharecompare shares in percentage points

Chart axes: car age, years · failure-rate scale 0–59%.

Takeaway: solid line: this family; dashed: all cars; from about age 16 it stays above the national age curve.

Does the month of a Chevrolet Kalos MOT matter?

Nov is highest at 54.8%; May is lowest at 51.4% — the gap is 3.3 percentage points.

higher = larger sharecompare shares in percentage points

Chart scale: 27%–56%.

bars: Chevrolet Kalos · dashed: all class-4 cars

Takeaway: the spread between best and worst month is 3.3 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.

Chevrolet Kalos average mileage by age

At age 18, the middle half of Kalos models runs from 49,612 miles to 85,745 miles, against 65,080 miles as the median.

Does high mileage mean more Chevrolet Kalos 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+, 42.7% of those with under 40,000 miles failed first time versus 62.1% of those with 100,000–140,000 miles.Inside this age group, higher mileage goes with more failures.

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

A typical 18-year-old Kalos has ~65,080 miles on the clock. Much more — ask why; much less — check for gaps in the MOT history.

How many miles does a Chevrolet Kalos last?

100,000+ miles stands out at 9.0%.

higher = larger sharecompare shares in percentage points

Of 28,429 tests of this family with a usable odometer in 2024, 9.0% had reached 100k miles. This is a cross-section of cars still presenting for MOT, not a full birth cohort.

Chevrolet Kalos faults that come together

Road Wheels + Tyres stand out at 3.96×, against 1.00× 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 3.35× more often than chance (732 co-occurrences in the same test; lift≥1.3, n≥500).

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 Chevrolet Kalos?

Cars driven under 5,000 miles a year is well below the reference at 44.9%, against 62.5% 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 44.9% vs 62.5% for 8–12k miles/year — 17.6 pp lower (n_low=8,907, n_normal=1,131). 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.

Best year for a Chevrolet Kalos, and the years to avoid

Build year 2005 is highest at 102.6; Build year 2007 is lowest at 96.3 — the gap is 6.3 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 2007 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 — 1 of 4 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.

Chevrolet Kalos MOT repair costs

The MOT-failure repair budget per test runs from £185.24 to £351.96, 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 £185 to £352, 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.

Chevrolet Kalos running costs for a fleet

Vehicles failing at age 19 are close to the reference at 55.0%, against 55.0% at age 16, 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.

Chevrolet Kalos rust problems: where they corrode

Age-standardised corrosion susceptibility stands out at 4.55×, against 1.00× for the national age-standardised rate.

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

This Chevrolet Kalos 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.

Does a Chevrolet Kalos advisory become a failure?

Lamps, reflectors and electrical equipment are highest at 37.2%; Non-component advisories are lowest at 0.0% — the gap is 37.2 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 37 in 100 cars, and the median gap is 12.1 months and roughly 3,422 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 Chevrolet Kalos?

Lamps, reflectors and electrical equipment after a failure at age 15-19 are highest at 35.3%; Brakes after a passed at age 15-19 are lowest at 13.0% — the gap is 22.4 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.

Chevrolet Kalos ownership: what six years of MOTs show

The ten-day re-test pass rate is highest at 62.2%; The later re-test pass rate is lowest at 3.8% — the gap is 58.4 percentage points.

higher = larger sharecompare shares in percentage points

Failing is usually a same-week event, not a disaster. Of 11,030 failures followed through to their re-test, 33.98% were repaired and passed the same day and 62.19% within ten days; the median gap is 1 day. 36,416 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 1.376 failures per 10,000 miles, on a median of 2,742 miles a year across 6,299 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. 16.63% of these cars strung together three or more tests with nothing recorded at all, while 44.36% 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: 1.092% of 6,320 chains show a reading lower than the previous test, with a median drop of 8,534 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.

Chevrolet Kalos safety recalls and how to check yours

DVSA recall campaigns stand out at 1.

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

DVSA lists 1 safety recall campaigns for the Chevrolet Kalos, covering roughly 38,876 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.

Chevrolet Kalos inspection results in other countries

Finland Katsastus stands out at 55.3%, against 26.3% nationally.

higher = larger sharecompare shares in percentage points

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.

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 2.147 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 Chevrolet Kalos 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.

Chevrolet Kalos MOT: quick answers

Chevrolet Kalos MOT Risk Index stands out at 122.3, 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 Chevrolet Kalos first-time MOT pass rate?

47.04% of first attempts passed in 2024 (2,430 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 52.96% figure is the first-time initial failure rate, using 2,430 primary tests as the denominator (first-time, excluding retests). The age-adjusted MOT initial-failure ratio 122.3 is shown separately because raw rates compare fleet age as well as cars.
