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 testFails next yearVehicles followed
It failed12.8%890
It passed11.9%23,311

A failed test does not clearly change next year's odds here (12.8% against 11.9%): the difference is within the margin of error. The failure most likely to come back is visibility — 17.7% 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 36,004 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 forIndexReading
Age only52.1fails less often than expected
Age and annual mileage52.5fails less often than vehicles driven as much
Share doing under 3,000 miles a year4.5%a normal spread of use

Mileage changes little here (+0.4 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 Porsche Panamera 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.

Is a Porsche Panamera ULEZ compliant?

The share of classifiable 2024 Porsche Panamera MOT tests likely ULEZ compliant by first-registration date is 71.7%.

Based on 7,132 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.

Takeaway: the spread between best and worst month is 2.9 percentage points — booking month barely matters for this family. 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 Porsche Panamera MOT failures at the same age?

Within the same age group, split by odometer (2024 MOTs), so this separates wear from age: at ages 10–14, 10.3% of those with under 40,000 miles failed first time versus 20.5% of those with over 140,000 miles.No clear mileage gap inside this age group, among cars still being tested.

Which Porsche Panamera engine is best?

diesel over 2.0 is highest at 109.0; petrol over 2.0 is lowest at 88.5 — the gap is 20.5 points.

petrolover 2.0 litre88.511.06%12,410
dieselover 2.0 litre10914.57%14,754

Splitting this model by fuel alone hides the thing that actually differs. Within the same badge, the diesel over 2.0 runs at 109 against this model's own age norm while the petrol over 2.0 runs at 88.5 — a spread of 20.5 points between two cars that share a name.

Read this one with more care than the rest of the page. Age is held constant, but who buys which engine is not: the largest capacity in a range is often a performance or executive variant that is garaged, cherished and lightly driven, while the smallest is frequently a fleet or entry car worked hard from new. The gap below is real in the test records; how much of it is the engine and how much is the owner, this data cannot separate. Bands under 100 tests are not shown; bands under 5,000 tests are rough estimates.

The best build year here is 2017 and the weakest is 2013. 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 — 3 of 12 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.

Porsche Panamera MOT repair costs

The MOT-failure repair budget per test runs from £20.69 to £39.31, against £54.85 for the test itself.

Brakes2.1 (nat. 11.25)Front brake pads (parts + labour, typical hatchback)£150£3.15

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 £21 to £39, 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.

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.

Porsche Panamera rust problems: where they corrode

Age-standardised corrosion susceptibility is well below the reference at 0.16×, against 1.00× for the national age-standardised rate.

Salt Belt exposure

percentile among the models published here, from its tests across 5 postcode areas

This Porsche Panamera fails on corrosion much less often than average 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.

Does a Porsche Panamera advisory become a failure?

Tyres are highest at 8.1%; Non-component advisories are lowest at 0.0% — the gap is 8.1 percentage points.

Non-component advisories0.0%——993

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 8 in 100 cars, and the median gap is 12.1 months and roughly 6,014 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 Porsche Panamera?

Lamps, reflectors and electrical equipment after a advisory at age 12-14 are highest at 8.4%; Lamps, reflectors and electrical equipment after a passed at age <3 are lowest at 0.9% — the gap is 7.5 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.

Failing is usually a same-week event, not a disaster. Of 3,409 failures followed through to their re-test, 23.53% were repaired and passed the same day and 71.55% within ten days; the median gap is 2 days. 5,978 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 0.192 failures per 10,000 miles, on a median of 5,557 miles a year across 7,227 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. 62.78% of these cars strung together three or more tests with nothing recorded at all, while 11.29% 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: 0.609% of 7,230 chains show a reading lower than the previous test, with a median drop of 12,244 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 24 safety recall campaigns for the Porsche Panamera, covering roughly 41,591 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.

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
The contact owns a 2017 Porsche Panamera. The contact received notification of NHTSA Campaign Number: 23V033000 (Electrical System) however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.
NHTSA complaint, filed 03/21/2023 · ELECTRICAL SYSTEM
This vehicle has an engine which has rocker arms that are known to fail. The manufacturer has not issued a recall to fix this issue which can result in a catastrophic engine failure. They have acknowledged the rocker arms in pre 2018 models to be defective and insufficiently reinforced to handle the strain of the valve train.
NHTSA complaint, filed 07/27/2025 · ENGINE

US owners have filed 30 complaints about the equivalent Porsche Panamera to the National Highway Traffic Safety Administration, including 3 that mention a crash, 0 a fire and 2 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.

Useful as a cross-check on the UK defect table above: the categories are named differently, but a component that dominates in both regimes is a genuine weak point of the model rather than an artefact of one country's testing style.

Worth dwelling on how mundane the top of that list is: tyre pressure, tread depth, headlight aim. The Dutch APK records 0.616 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 Porsche Panamera 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.

Porsche Panamera MOT: quick answers

Porsche Panamera MOT Risk Index is well below the reference at 50.9, 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 Porsche Panamera first-time MOT pass rate?
87.23% of first attempts passed in 2024 (7,148 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 12.77% figure is the first-time initial failure rate, using 7,148 primary tests as the denominator (first-time, excluding retests). The age-adjusted MOT initial-failure ratio 50.9 is shown separately because raw rates compare fleet age as well as cars.

Compare the Porsche Panamera with other cars

Porsche Panamera is highest at 50.9; Mercedes-Benz SL is lowest at 47.6 — the gap is 3.3 points.

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.
