Honda NSX — MOT statistics 2024

The Honda NSX failed 5.44% of 386 first MOT attempts in 2024 ("first-time", excluding retests). Adjusted for the age of the fleet, its initial-failure ratio is 16.8 (100 = expected for its age profile). This car fails its MOT about 83% less often than expected for its age. Small sample — treat with care.

Age-adjusted peer: Ferrari 599 (index 16.4) — the two published results are 0.4 index points apart.

Honda NSX common problems: what actually fails the MOT

Lamps, reflectors and electrical equipment are well below the reference at 5.1 per 100 tests, against 25.1 per 100 tests across UK vehicles of the same ages.

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 11.0 percentage points. 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 2,045 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.

Split by how much each car is driven. This is a split by annual mileage, not by body type — the MOT record does not say whether a car is a conversion. Within each band the index compares with vehicles of the same age driven as much.

Mileage changes little here (+3.9 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 does the Honda NSX perform as it gets older?

The NSX at age 20 is well below the reference at 5.5%, against 41.0% for all vehicles of the same age.

Does the month of a Honda NSX MOT matter?

Nov is highest at 15.3%; Sep is lowest at 5.6% — the gap is 9.7 percentage points.

higher = larger sharecompare shares in percentage points

Chart scale: 4%–33%.

bars: Honda NSX · dashed: all class-4 cars

Takeaway: the spread between best and worst month is 9.7 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.

Honda NSX average mileage by age

At age 20+, the middle half of NSX models runs from 39,480 miles to 83,815 miles, against 57,774 miles as the median.

Where in Britain the Honda NSX fails its MOT most

London NW area is highest at 14.3%; Redhill area is lowest at 1.5% — the gap is 12.8 percentage points.

higher = larger sharecompare shares in percentage points

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.

Honda NSX survival: which cars are still on the road

By age 19 is well below the reference at 58.1%, 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 19, only about 58% as many cars of this family present for MOT as at ages 4–6 (reference n≈103); survivors still fail at 3.3% vs 10.3% at age 4. Older cars that still appear are a selected subset — weaker ones have already left.

How many years is a Honda NSX likely to last?

Bought at age 5 stands out at 9.8 years.

estimateObserved only until age 19. 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.

Honda NSX faults that come together

Defects in «Lamps, reflectors and electrical equipment» and «Visibility» were seen together in 17 tests (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).

Honda NSX MOT repair costs

The MOT-failure repair budget per test runs from £16.39 to £31.14, 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 £16 to £31, 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.

Honda NSX rust problems: where they corrode

Salt-belt exposure is well below the reference at 9th percentile, against 50th percentile as the middle of published models.

higher = larger sharecompare shares in percentage points

This Honda NSX 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.

What will fail next on a Honda NSX?

Lamps, reflectors and electrical equipment after a failure at age 20+ are highest at 10.9%; Brakes after a passed at age 20+ are lowest at 1.6% — the gap is 9.4 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.

Honda NSX safety recalls and how to check yours

DVSA recall campaigns stand out at 3.

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

recall campaigns launched per year

DVSA lists 3 safety recall campaigns for the Honda NSX, covering roughly 230 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.

Honda NSX MOT: quick answers

Honda NSX MOT Risk Index is well below the reference at 16.8, 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 Honda NSX first-time MOT pass rate?

94.56% of first attempts passed in 2024 (386 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 5.44% figure is the first-time initial failure rate, using 386 primary tests as the denominator (first-time, excluding retests). The age-adjusted MOT initial-failure ratio 16.8 is shown separately because raw rates compare fleet age as well as cars.
