DS DS4 — MOT statistics 2024

The DS DS4 failed 32.92% of 4,489 first MOT attempts in 2024 ("first-time", excluding retests). Adjusted for the age of the fleet, its initial-failure ratio is 145.6 (100 = expected for its age profile). This car fails its MOT about 46% more often than expected for its age. Small sample — treat with care.

Age-adjusted peer: DS 3 (index 146.1) — the two published results are 0.5 index points apart.

DS DS4 common problems: what actually fails the MOT

Lamps, reflectors and electrical equipment stand out at 12.3 per 100 tests, against 5.2 per 100 tests across UK vehicles of the same ages.

Tyres, brakes and suspension: DS DS4 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.

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 5.3 percentage points. The failure most likely to come back is lamps, reflectors and electrical equipment — 30.9% 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 25,685 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 changes little here (+0.5 points): this fleet is driven about as much as the vehicles it is compared with. 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 DS DS4 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 DS DS4 perform as it gets older?

The DS4 at age 8 stands out at 33.8%, against 23.3% for all vehicles of the same age.

higher = larger sharecompare shares in percentage points

Chart axes: car age, years · failure-rate scale 0–39%.

Takeaway: solid line: this family; dashed: all cars; from about age 7 it stays above the national age curve.

How dangerous are DS DS4 MOT failures?

Major defects are well below the reference at 27.1 per 100 tests, against 52.8 per 100 tests nationally.

Does the month of a DS DS4 MOT matter?

Oct is highest at 27.6%; Mar is lowest at 22.0% — the gap is 5.6 percentage points.

higher = larger sharecompare shares in percentage points

Chart scale: 21%–33%.

bars: DS DS4 · dashed: all class-4 cars

Takeaway: the spread between best and worst month is 5.6 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.

DS DS4 average mileage by age

At age 8, the middle half of DS4s runs from 48,566 miles to 76,174 miles, against 60,784 miles as the median.

Does high mileage mean more DS DS4 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, 23.9% of those with under 40,000 miles failed first time versus 45.5% of those with 100,000–140,000 miles.Inside this age group, higher mileage goes with more failures.

A typical 8-year-old DS4 has ~60,784 miles on the clock. Much more — ask why; much less — check for gaps in the MOT history.

DS DS4 survival: which cars are still on the road

By age 9 is well below the reference at 17.6%, 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 9, only about 18% as many cars of this family present for MOT as at ages 4–6 (reference n≈4,566); survivors still fail at 36.6% vs 19.2% at age 4. Older cars that still appear are a selected subset — weaker ones have already left.

How many miles does a DS DS4 last?

100,000+ miles stands out at 2.3%.

higher = larger sharecompare shares in percentage points

Of 25,683 tests of this family with a usable odometer in 2024, 2.3% 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 DS DS4 likely to last?

Bought at age 5 is highest at 3.3 years; Bought at age 8 is lowest at 0.8 years — the gap is 2.5 years.

bigger number = longer remaining lifeyears on the observed survival curve

estimateObserved only until age 9. 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.

DS DS4 faults that come together

Body & structure + Emissions & leaks stand out at 5.07×, 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 5.07× more often than chance (111 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 DS DS4?

Cars driven under 5,000 miles a year is well below the reference at 16.5%, against 30.3% 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 16.5% vs 30.3% for 8–12k miles/year — 13.8 pp lower (n_low=2,048, n_normal=4,381). 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.

Which DS DS4 engine is best?

diesel 1.5–1.8 is highest at 104.5; petrol 1.5–1.8 is lowest at 73.4 — the gap is 31.1 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 104.5 against this model's own age norm while the petrol 1.5–1.8 runs at 73.4 — a spread of 31.1 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 100 tests are not shown; bands under 5,000 tests are rough estimates.

Best year for a DS DS4, and the years to avoid

Build year 2015 is highest at 106.7; Build year 2017 is lowest at 96.3 — the gap is 10.4 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 2015 and the weakest is 2015. 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.

DS DS4 MOT repair costs

The MOT-failure repair budget per test runs from £45.21 to £85.90, 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 £45 to £86, 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.

DS DS4 running costs for a fleet

Vehicles failing at age 9 stand out at 37.0%, against 28.0% at age 6, 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.

DS DS4 rust problems: where they corrode

Age-standardised corrosion susceptibility is well below the reference at 0.1×, against 1.00× for the national age-standardised rate.

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

This DS DS4 virtually never fails on corrosion once age is held constant, and its owners live in areas that are saltier than most for the models we publish. Both point the same way and reinforce each other: it resists corrosion even though its owners live in saltier areas than most.

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 DS DS4 advisory become a failure?

Tyres are highest at 9.5%; Non-component advisories are lowest at 0.0% — the gap is 9.5 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 10 in 100 cars, and the median gap is 12 months and roughly 7,218 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 DS DS4?

Lamps, reflectors and electrical equipment after a failure at age 6-8 are highest at 17.4%; Visibility after a advisory at age <3 is lowest at 4.7% — the gap is 12.6 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.

DS DS4 ownership: what six years of MOTs show

The same-day re-test pass rate is highest at 49.7%; The later re-test pass rate is lowest at 2.0% — the gap is 47.8 percentage points.

higher = larger sharecompare shares in percentage points

Failing is usually a same-week event, not a disaster. Of 4,660 failures followed through to their re-test, 49.72% were repaired and passed the same day and 48.3% within ten days; the median gap is 1 day. 9,622 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 0.374 failures per 10,000 miles, on a median of 6,400 miles a year across 4,545 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. 43.99% of these cars strung together three or more tests with nothing recorded at all, while 26.83% 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: 0.814% of 4,545 chains show a reading lower than the previous test, with a median drop of 12,633 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.

DS DS4 safety recalls and how to check yours

DVSA recall campaigns stand out at 6.

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

recall campaigns launched per year

DVSA lists 6 safety recall campaigns for the DS DS4, covering roughly 955 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.

DS DS4 MOT: quick answers

DS DS4 MOT Risk Index stands out at 145.6, 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 DS DS4 first-time MOT pass rate?

67.08% of first attempts passed in 2024 (4,489 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 32.92% figure is the first-time initial failure rate, using 4,489 primary tests as the denominator (first-time, excluding retests). The age-adjusted MOT initial-failure ratio 145.6 is shown separately because raw rates compare fleet age as well as cars.
