Mercedes-Benz EQC — MOT statistics 2024

The Mercedes-Benz EQC failed 16.47% of 7,205 first MOT attempts in 2024 ("first-time", excluding retests). Adjusted for the age of the fleet, its initial-failure ratio is 131.1 (100 = expected for its age profile). This car fails its MOT about 31% more often than expected for its age.

Age-adjusted peer: Renault Megane (index 131.0) — the two published results are 0.1 index points apart.

Mercedes-Benz EQC common problems: what actually fails the MOT

Tyres stand out at 16.2 per 100 tests, against 10.5 per 100 tests across UK electric vehicles of the same ages.

Tyres, brakes and suspension: Mercedes-Benz EQC 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 does not clearly change next year's odds here (14.5% against 13.1%): the difference is within the margin of error. 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 10,349 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 11.0 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 Mercedes-Benz EQC 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 Mercedes-Benz EQC perform as it gets older?

The EQC at age 3 stands out at 17.9%, against 12.4% for all vehicles of the same age.

Does the month of a Mercedes-Benz EQC MOT matter?

Dec is highest at 17.1%; Feb is lowest at 12.9% — the gap is 4.2 percentage points.

higher = larger sharecompare shares in percentage points

Chart scale: 11%–33%.

bars: Mercedes-Benz EQC · dashed: all class-4 cars

Takeaway: the spread between best and worst month is 4.2 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.

Mercedes-Benz EQC average mileage by age

At age 4, the middle half of EQCs runs from 24,887 miles to 43,979 miles, against 34,035 miles as the median.

further right = more milesmedian is the typical car; band is p25–p75

Does high mileage mean more Mercedes-Benz EQC 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, 16.3% of those with under 40,000 miles failed first time versus 18% of those with 70,000–100,000 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 EQC has ~34,035 miles on the clock. Much more — ask why; much less — check for gaps in the MOT history.

Mercedes-Benz EQC survival: which cars are still on the road

By age 5 is well below the reference at 5.1%, against 100.0% at the ages 4–6 reference level.

higher = larger sharecompare shares in percentage points

By age 5, only about 5% as many cars of this family present for MOT as at ages 4–6 (reference n≈2,826); survivors still fail at 14.5% vs 14.1% at age 4. Older cars that still appear are a selected subset — weaker ones have already left.

How many years is a Mercedes-Benz EQC likely to last?

Bought at age 5 stands out at 0.5 years.

bigger number = longer remaining lifeyears on the observed survival curve

estimateObserved only until age 5. 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.

Mercedes-Benz EQC faults that come together

Brakes + Tyres stand out at 4.82×, against 1.00× if the faults were independent.

above 1.0× = more than expectedbelow 1.0× = less

Defects in «Brakes» and «Tyres» appear together 4.82× more often than chance (20 co-occurrences in the same test; 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).

Is low mileage better for a Mercedes-Benz EQC?

Cars driven under 5,000 miles a year is well below the reference at 5.9%, against 12.8% 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 5.9% vs 12.8% for 8–12k miles/year — 6.9 pp, interval includes no difference (n_low=34, n_normal=47). The gap interval includes no difference, so no higher/lower claim is made.

Best year for a Mercedes-Benz EQC, and the years to avoid

Build year 2020 is highest at 96.5; Build year 2019 is lowest at 39.1 — the gap is 57.4 points.

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

The best build year here is 2019 and the weakest is 2019. 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 2 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.

Mercedes-Benz EQC MOT repair costs

The MOT-failure repair budget per test runs from £18.04 to £34.28, 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 £18 to £34, 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.

Mercedes-Benz EQC running costs for a fleet

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.

Mercedes-Benz EQC rust problems: where they corrode

Age-standardised corrosion susceptibility is well below the reference at 0.4×, against 1.00× for the national age-standardised rate.

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

This Mercedes-Benz EQC fails on corrosion much less often than average 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.

Does a Mercedes-Benz EQC advisory become a failure?

Tyres stand out at 11.6%.

higher = more likelypercentage is the observed transition probability

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 12 in 100 cars, and the median gap is 11.8 months and roughly 8,472 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 Mercedes-Benz EQC?

Tyres after a advisory at age 3-5 are highest at 12.3%; Suspension after a passed at age <3 is lowest at 1.6% — the gap is 10.7 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.

Mercedes-Benz EQC ownership: what six years of MOTs show

The ten-day re-test pass rate is highest at 59.0%; The later re-test pass rate is lowest at 2.0% — the gap is 57.0 percentage points.

higher = larger sharecompare shares in percentage points

Failing is usually a same-week event, not a disaster. Of 1,333 failures followed through to their re-test, 38.93% were repaired and passed the same day and 59.04% within ten days; the median gap is 1 day. 2,009 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 0.17 failures per 10,000 miles, on a median of 7,727 miles a year across 2,851 chains. This is the number to compare between models — an annual rate quietly rewards cars that barely leave the drive.

Odometer anomalies: 0.245% of 2,859 chains show a reading lower than the previous test, with a median drop of 8,434 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.

Mercedes-Benz EQC safety recalls and how to check yours

DVSA recall campaigns stand out at 17.

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

recall campaigns launched per year

DVSA lists 17 safety recall campaigns for the Mercedes-Benz EQC, covering roughly 708,238 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.

Mercedes-Benz EQC inspection results in other countries

Norway PKK is well below the reference at 9.2%, against 33.7% 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.

Worth dwelling on how mundane the top of that list is: tyre pressure, tread depth, headlight aim. The Dutch APK records 0.655 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 Mercedes-Benz EQC 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.

One caveat before you read the UK row: these are raw failure rates, because no other country publishes the age detail our index needs. This model's raw UK rate looks better than the national average while its age-adjusted index is 131.1 — the fleet here is unusually young, and the raw column silently credits that. The index above is the fair comparison; this table is for reading each country against itself.

Mercedes-Benz EQC MOT: quick answers

Mercedes-Benz EQC MOT Risk Index stands out at 131.1, 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 Mercedes-Benz EQC first-time MOT pass rate?

83.53% of first attempts passed in 2024 (7,205 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 16.47% figure is the first-time initial failure rate, using 7,205 primary tests as the denominator (first-time, excluding retests). The age-adjusted MOT initial-failure ratio 131.1 is shown separately because raw rates compare fleet age as well as cars.
