Mercedes-Benz EQA — MOT statistics 2024

The Mercedes-Benz EQA failed 12.08% of 5,109 first MOT attempts in 2024 ("first-time", excluding retests). Adjusted for the age of the fleet, its initial-failure ratio is 99.0 (100 = expected for its age profile). This car is too close to call — statistically indistinguishable from normal for its age.

Age-adjusted peer: Kia Optima (index 99.0) — the two published results are 0.0 index points apart.

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

Visibility stands out at 5.4 per 100 tests, against 3.7 per 100 tests across UK electric vehicles of the same ages.

higher bar = fails more oftenrate per 100 tests

family vs national — matched to UK electric vehicles of the same ages — top component groups, per 100 tests. Legend: This family · National avg. Combined labels: family / national average. 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.

Named defects ranked by how much more often they appear than the national average — not by raw rate.

Mercedes-Benz EQA MOT advisories: what gets flagged

Tyres are highest at 57.3 per 100 tests; Brakes are lowest at 1.0 per 100 tests — the gap is 56.3 per 100 tests.

Tyres, brakes and suspension: Mercedes-Benz EQA 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 5,222 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 (-3.4 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 Mercedes-Benz EQA 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 EQA perform as it gets older?

The EQA at age 3 is close to the reference at 12.2%, against 12.4% for all vehicles of the same age.

Chart axes: car age, years · failure-rate scale 0–14%.

Takeaway: solid line: this family; dashed: all cars.

How dangerous are Mercedes-Benz EQA MOT failures?

Major defects are well below the reference at 8.8 per 100 tests, against 52.8 per 100 tests nationally.

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

Jun is highest at 13.7%; Jan is lowest at 2.6% — the gap is 11.1 percentage points.

higher = larger sharecompare shares in percentage points

Chart scale: 1%–33%.

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

Takeaway: the spread between best and worst month is 11.1 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 EQA average mileage by age

At age 3, the middle half of EQAs runs from 16,633 miles to 32,938 miles, against 23,916 miles as the median.

Does high mileage mean more Mercedes-Benz EQA 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, 11.2% of those with under 40,000 miles failed first time versus 19.2% of those with 40,000–70,000 miles.Inside this age group, higher mileage goes with more failures.

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

A typical 3-year-old EQA has ~23,916 miles on the clock. Much more — ask why; much less — check for gaps in the MOT history.

Where in Britain the Mercedes-Benz EQA fails its MOT most

Too few tests in any single postcode area to name one, so this is the wider picture across 5,225 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.

Mercedes-Benz EQA faults that come together

Tyres + Visibility stand out at 2.61×, against 1.00× if the faults were independent.

above 1.0× = more than expectedbelow 1.0× = less

Defects in «Tyres» and «Visibility» appear together 2.61× more often than chance (54 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).

Mercedes-Benz EQA 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 Mercedes-Benz EQA virtually never fails on corrosion once age is held constant, and its owners live in areas that are gentler 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.

What will fail next on a Mercedes-Benz EQA?

Tyres after a passed at age <3 stand out at 4.2%.

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 EQA safety recalls and how to check yours

DVSA recall campaigns stand out at 5.

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

recall campaigns launched per year

DVSA lists 5 safety recall campaigns for the Mercedes-Benz EQA, covering roughly 23,542 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 EQA MOT: quick answers

Mercedes-Benz EQA MOT Risk Index is close to the reference at 99.0, 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 EQA first-time MOT pass rate?

87.92% of first attempts passed in 2024 (5,109 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 12.08% figure is the first-time initial failure rate, using 5,109 primary tests as the denominator (first-time, excluding retests). The age-adjusted MOT initial-failure ratio 99.0 is shown separately because raw rates compare fleet age as well as cars.
