BMW X5 — MOT statistics 2024
The BMW X5 failed 20.81% of 91,002 first MOT attempts in 2024 ("first-time", excluding retests). Adjusted for the age of the fleet, its initial-failure ratio is 73.5 (100 = expected for its age profile). This car fails its MOT about 26% less often than expected for its age.
Age-adjusted peer: Audi TT (index 73.4) — the two published results are 0.1 index points apart.
BMW X5 common problems: what actually fails the MOT
Lamps, reflectors and electrical equipment are well below the reference at 15.5 per 100 tests, against 19.5 per 100 tests across UK vehicles of the same ages.

family vs national — matched to UK 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.
Component-group comparison table
Each ratio carries a 95% interval. With 6 groups compared here, roughly one apparent difference in twenty is chance alone.

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.
| After this year's test | Fails next year | Vehicles followed |
|---|---|---|
| It failed | 29.0% | 24,614 |
| It passed | 20.0% | 285,300 |
A failed test raises next year's chance of failing again by 9.0 percentage points. The failure most likely to come back is body, chassis, structure — 32.0% 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 515,254 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.
| Standardised for | Index | Reading |
|---|---|---|
| Age only | 78.8 | fails less often than expected |
| Age and annual mileage | 73.0 | fails less often than vehicles driven as much |
| Share doing under 3,000 miles a year | 1.0% | a normal spread of use |
Mileage matters here: matching on how much these are driven moves the figure by 5.8 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.

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.

Is a BMW X5 ULEZ compliant?
The share of classifiable 2024 BMW X5 MOT tests likely ULEZ compliant by first-registration date is 49.4%.
Based on 90,556 classifiable initial MOT tests. This describes the tested fleet, not a specific car. MOT data do not record Euro class, so likely compliance is inferred from fuel and first-registration date. For the only authoritative answer, check the registration with TfL's official ULEZ checker.

| Dec | 22.69% | 29.33% | -6.6 pp |
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.

Does high mileage mean more BMW X5 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, 11.5% of those with under 40,000 miles failed first time versus 17.3% of those with over 140,000 miles.Inside this age group, higher mileage goes with more failures.

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 urban share this model fails 7.6 pp less often than in the lowest fifth (r=-0.50, n=113 areas with ≥800 tests).
In areas with the highest mot centre density this model fails 6.7 pp more often than in the lowest fifth (r=0.42, n=113 areas with ≥800 tests).
In the most coastal fifth of areas this model fails 6.0 pp more often than in the most inland fifth (r=-0.41, n=113 areas with ≥800 tests).
| Factor | Low Q | High Q | Gap | Correlation |
|---|---|---|---|---|
| Urban share | 27.9% | 20.3% | -7.6 pp | r=-0.50 |
| MOT centre density | 21.2% | 27.8% | +6.6 pp | r=0.42 |
| Distance to coast | 28.9% | 22.8% | -6.1 pp | r=-0.41 |
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 | 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.

Deprivation uses England IMD 2019 income score only (Scotland SIMD is a different scale). Salt proxy is a simplified NWSRG-style dry-salt sum from air Tmin; coastalness is distance from the area centroid to the nearest coastline.
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.

The best build year here is 2014 and the weakest is 2006. 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 — 17 of 21 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.
BMW X5 MOT repair costs
The MOT-failure repair budget per test runs from £72.34 to £137.45, against £54.85 for the test itself.
bigger number = costs morepounds per test, MOT-failing faults only
| Component | Fails per 100 tests | Typical repair | Its price | Contribution |
|---|---|---|---|---|
| Suspension | 13.0 (nat. 15.36) | Suspension coil spring (single corner) | £180 | £23.40 |
| Lamps, reflectors and electrical equipment | 15.5 (nat. 18.09) | Battery replacement (standard 12V lead-acid) | £140 | £21.70 |
| Brakes | 11.5 (nat. 11.25) | Front brake pads (parts + labour, typical hatchback) | £150 | £17.25 |
| Tyres | 11.1 (nat. 8.7) | Tyre (single mid-range 16" fitted) | £90 | £9.99 |
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 £72 to £137, 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.

The number a fleet manager needs is not the failure rate, it is the year the car starts costing more. Between cars aged 17 and cars aged 18, both tested in 2024, the failure rate of this model is 7.05 percentage points higher — the steepest one-year step in this cross-section of different cars, and a 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.

Age-standardised corrosion susceptibility is well below the reference at 0.62×, against 1.00× for the national age-standardised rate.
above 1.0× = rusts more than averagebelow 1.0× = rusts less
This BMW X5 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 BMW X5 advisory become a failure?
Lamps, reflectors and electrical equipment are highest at 27.9%; Road wheels are lowest at 2.5% — the gap is 25.4 percentage points.

| Component | Fails next time | Typical lead time | Miles of warning | Advisories tracked |
|---|---|---|---|---|
| Lamps, reflectors and electrical equipment | 27.9% | 12.1 months | 4,920 | 6,674 |

| Steering | 7.5% | 12.1 months | 5,170 | 2,866 |
| Seat belts and supplementary restraint systems | 4.2% | 12.1 months | 5,994 | 2,364 |
| Noise, emissions and leaks | 3.5% | 12.1 months | 5,106 | 24,344 |
| Identification of the vehicle | 3.4% | 12.2 months | 6,921 | 5,648 |
| Road wheels | 2.5% | 12.7 months | 6,090 | 553 |
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 28 in 100 cars, and the median gap is 12.1 months and roughly 4,920 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 BMW X5?
Lamps, reflectors and electrical equipment after a failure at age 20+ are highest at 29.2%; Lamps, reflectors and electrical equipment after a passed at age <3 are lowest at 0.9% — the gap is 28.3 percentage points.

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.
BMW X5 ownership: what six years of MOTs show
The ten-day re-test pass rate is highest at 68.3%; The later re-test pass rate is lowest at 4.9% — the gap is 63.3 percentage points.
higher = larger sharecompare shares in percentage points
Failing is usually a same-week event, not a disaster. Of 94,023 failures followed through to their re-test, 26.83% were repaired and passed the same day and 68.26% within ten days; the median gap is 1 day. 240,103 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 0.32 failures per 10,000 miles, on a median of 6,463 miles a year across 103,558 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. 41.2% of these cars strung together three or more tests with nothing recorded at all, while 25.48% 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: 1.349% of 103,674 chains show a reading lower than the previous test, with a median drop of 33,505 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.

DVSA lists 70 safety recall campaigns for the BMW X5, covering roughly 1,573,141 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.

Caveat worth stating plainly: this is NHTSA data about US-specification cars. British cars sold under the same name often use different gearboxes, engines and equipment, so a bulletin may describe a component that was never fitted here. The file counts dealer communications, not affected vehicles or confirmed failures, and it cannot tell you whether an individual UK car has the issue. A communication can carry more than one subject tag, so topic counts do not have to add up to the total.

US market, BMW X5 and its variants, model years 2015–2022 only. A count of owner complaints, not a UK failure rate; NHTSA has no UK denominator.
Engine (not MOT-tested) is highest at 265; Brakes are lowest at 44 — the gap is 221.
bigger number = more recorded casescompare like-for-like scope, not sample size alone
| Component | Complaints | Share | MOT fail items per 100 | MOT rank | Agreement |
|---|---|---|---|---|---|
| Engine (not MOT-tested) | 265 | 31.3% | not in top 6 | — | complained about, rarely an MOT failure |
| Lamps & electrical | 246 | 29.0% | 15.5 | #1 | complained about and fails often |
| Transmission (not MOT-tested) | 134 | 15.8% | not in top 6 | — | complained about, rarely an MOT failure |
| Restraints | 80 | 9.4% | not in top 6 | — | complained about, rarely an MOT failure |
| Brakes | 44 | 5.2% | 11.5 | #3 | complained about and fails often |
| Steering | 44 | 5.2% | not in top 6 | — | complained about, rarely an MOT failure |
Two different populations answering two different questions: the MOT records what an inspector can measure once a year, the complaint file records what annoyed or frightened an owner on the road. A component high in one column and absent from the other is the interesting case — driver-assistance and electronics dominate complaints while almost never appearing as an MOT failure item.
What the reports actually say
I am having a high voltage system box fault. I am within warranty but the dealership is denying me. My in service date is 6-2016.
1) Crankshaft Sensor MIL Light 2) Drive train malfunction, 3) Start and Stop malfunction, 3) MIL for Catalytic convertor 4) MIL light for Catalytic Convertor & O2 sensor failure. The Vehicle has (97,000 K), and the BMW dealer would not cover the costs. However there's TSB published for this vehicle, yet its not being honored by the dealer who claims that the Emissions warranty expired after 8 years or 80,000 miles.
US owners have filed 848 complaints about the equivalent BMW X5 to the National Highway Traffic Safety Administration, including 39 that mention a crash, 21 a fire and 30 an injury. These are owner reports, not verified findings — but they are the only large public record of what drivers themselves notice, and they cover the years between MOT tests.
Caveat worth stating plainly: US-specification cars, self-selected reporters, no denominator — complaint counts scale with how many cars were sold there and how motivated owners are to file. The mechanical gap matters as much as the statistical one: American cars of the same name often carry different gearboxes, engines and equipment — automatics where Britain buys manuals — so a drivetrain complaint filed in Ohio may describe a part that was never fitted here. Read the ranking inside a model, not between models, and treat drivetrain entries with particular caution.

BMW X5 inspection results in other countries
Netherlands APK is well below the reference at 34.4%, against 50.8% nationally.
higher = larger sharecompare shares in percentage points
| Country | Test | This model fails | National average | Position | Sample |
|---|---|---|---|---|---|
| United Kingdom | MOT (class 4) | 20.81% | 26.01% | -5.2 pp | 91,002 |
| Norway | PKK | 31.2% | 33.7% | -2.5 pp | 9,265 |
| Netherlands | APK | 34.4% | 50.8% | -16.4 pp | 9,010 |
| Finland | Katsastus | 23.2% | 26.3% | -3.1 pp | 5,585 |
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.
| Code | Fault | Recorded | Type |
|---|---|---|---|
210 | Tyre pressure not at the correct value | 1,238 | failure |
AC4 | Steering or suspension ball joint worn up to 1.0 mm | 782 | advisory |
205 | Tyre with insufficient tread | 601 | failure |
516 | Dipped headlight incorrectly aimed | 547 | failure |
AC1 | Tyre down to 1.6–2.5 mm of tread | 421 | advisory |
203 | Tyre damaged | 366 | failure |
RA2 | Excessive leak of other fluids | 262 | advisory |
186 | Ball joint with excessive play | 232 | failure |
Worth dwelling on how mundane the top of that list is: tyre pressure, tread depth, headlight aim. The Dutch APK records 0.679 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 BMW X5 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.

BMW X5 MOT: quick answers
BMW X5 MOT Risk Index is well below the reference at 73.5, 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 BMW X5 first-time MOT pass rate?
- 79.19% of first attempts passed in 2024 (91,002 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 20.81% figure is the first-time initial failure rate, using 91,002 primary tests as the denominator (first-time, excluding retests). The age-adjusted MOT initial-failure ratio 73.5 is shown separately because raw rates compare fleet age as well as cars.

Data details & how to cite
Scope: class-4 vehicles (cars), initial tests only, outcomes pass / fail / fixed-on-the-spot at the station (PRS counts towards the failure rate — the defect was present at arrival). Index = observed initial failures ÷ failures expected for this fleet's exact age profile, ×100; margin of error is a 95% confidence interval. Covers ALL generations together — a 3-year-old and a 15-year-old are very different cars; a generation split is on the roadmap.
