Rolls-Royce Cullinan — MOT statistics 2024

The Rolls-Royce Cullinan failed 2.99% of 268 first MOT attempts in 2024 ("first-time", excluding retests). Adjusted for the age of the fleet, its initial-failure ratio is 21.4 (100 = expected for its age profile). This car fails its MOT about 79% less often than expected for its age. Small sample — treat with care.

Age-adjusted peer: Aston Martin V8 (index 21.2) — the two published results are 0.2 index points apart.

Rolls-Royce Cullinan common problems: what actually fails the MOT

Tyres are well below the reference at 1.9 per 100 tests, against 6.1 per 100 tests across UK vehicles of the same ages.

higher bar = fails more oftenrate per 100 tests

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. This model rarely fails at all: the groups below rest on 12 failed items in total, so read them as a shape, not a rate. 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.

Rolls-Royce Cullinan MOT advisories: what gets flagged

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 644 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 5.5 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 Rolls-Royce Cullinan 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 Rolls-Royce Cullinan perform as it gets older?

The Cullinan at age 5 is well below the reference at 1.8%, against 15.1% for all vehicles of the same age.

Chart axes: car age, years · failure-rate scale 0–19%.

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

How dangerous are Rolls-Royce Cullinan MOT failures?

Major defects are well below the reference at 1.2 per 100 tests, against 52.8 per 100 tests nationally.

Does the month of a Rolls-Royce Cullinan MOT matter?

Aug is highest at 5.6%; May is lowest at 0.0% — the gap is 5.6 percentage points.

higher = larger sharecompare shares in percentage points

Chart scale: -1%–33%.

bars: Rolls-Royce Cullinan · 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.

Rolls-Royce Cullinan average mileage by age

At age 5, the middle half of Cullinans runs from 13,111 miles to 30,887 miles, against 21,911 miles as the median.

A typical 5-year-old Cullinan has ~21,911 miles on the clock. Much more — ask why; much less — check for gaps in the MOT history.

Rolls-Royce Cullinan survival: which cars are still on the road

By age 5 is well below the reference at 73.4%, against 100.0% at the ages 4–6 reference level.

higher = larger sharecompare shares in percentage points

By age 5, only about 73% as many cars of this family present for MOT as at ages 4–6 (reference n≈168); survivors still fail at 1.6% vs 2.4% at age 4. Older cars that still appear are a selected subset — weaker ones have already left.

How many years is a Rolls-Royce Cullinan likely to last?

Bought at age 5 stands out at 0.5 years.

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.

Rolls-Royce Cullinan rust problems: where they corrode

Salt-belt exposure is well below the reference at lowest percentile, against 50th percentile as the middle of published models.

higher = larger sharecompare shares in percentage points

This Rolls-Royce Cullinan has too few tests to judge for 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.

Rolls-Royce Cullinan 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 Rolls-Royce Cullinan, covering roughly 114 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.

Rolls-Royce Cullinan MOT: quick answers

Rolls-Royce Cullinan MOT Risk Index is well below the reference at 21.4, against 100 for a car with the same age profile.

What is the Rolls-Royce Cullinan first-time MOT pass rate?

97.01% of first attempts passed in 2024 (268 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 2.99% figure is the first-time initial failure rate, using 268 primary tests as the denominator (first-time, excluding retests). The age-adjusted MOT initial-failure ratio 21.4 is shown separately because raw rates compare fleet age as well as cars.
