Porsche Taycan — MOT statistics 2024

The Porsche Taycan failed 9.22% of 6,213 first MOT attempts in 2024 ("first-time", excluding retests). Adjusted for the age of the fleet, its initial-failure ratio is 73.0 (100 = expected for its age profile). This car fails its MOT about 27% less often than expected for its age.

Age-adjusted peer: Ford Mustang (index 73.1) — the two published results are 0.1 index points apart.

Porsche Taycan common problems: what actually fails the MOT

Visibility is well below the reference at 2.3 per 100 tests, against 4.2 per 100 tests across UK electric vehicles of the same ages.

Tyres, brakes and suspension: Porsche Taycan 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.

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 does not clearly change next year's odds here (8.3% against 8.0%): the difference is within the margin of error. 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 8,803 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 (+3.5 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 Taycan 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 Porsche Taycan perform as it gets older?

Does the month of a Porsche Taycan MOT matter?

Aug is highest at 11.4%; Mar is lowest at 7.0% — the gap is 4.4 percentage points.

higher = larger sharecompare shares in percentage points

Chart scale: 6%–33%.

bars: Porsche Taycan · dashed: all class-4 cars

Takeaway: the spread between best and worst month is 4.4 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.

Porsche Taycan average mileage by age

At age 4, the middle half of Taycans runs from 18,104 miles to 35,454 miles, against 25,734 miles as the median.

further right = more milesmedian is the typical car; band is p25–p75

Does high mileage mean more Porsche Taycan 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, 9% of those with under 40,000 miles failed first time versus 10.9% of those with 40,000–70,000 miles.No clear mileage gap inside this age group, among cars still being tested.

Porsche Taycan survival: which cars are still on the road

By age 4 is close to the reference at 100.0%, against 100.0% at the ages 4–6 reference level.

higher = larger sharecompare shares in percentage points

By age 4, only about 100% as many cars of this family present for MOT as at ages 4–6 (reference n≈2,611); survivors still fail at 8.8% vs 8.8% at age 4. Older cars that still appear are a selected subset — weaker ones have already left.

Porsche Taycan faults that come together

Tyres + Visibility stand out at 2.76×, against 1.00× if the faults were independent.

above 1.0× = more than expectedbelow 1.0× = less

Defects in «Tyres» and «Visibility» appear together 2.76× more often than chance (39 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).

Porsche Taycan running costs for a fleet

Vehicles failing at age 4 are well below the reference at 9.0%, against 10.0% at age 3, tested in the same year.

higher = larger sharecompare shares in percentage points

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 Taycan 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 Porsche Taycan 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 Porsche Taycan?

Tyres after a advisory at age <3 are highest at 9.5%; Brakes after a passed at age <3 are lowest at 0.6% — the gap is 8.9 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.

Porsche Taycan ownership: what six years of MOTs show

The ten-day re-test pass rate is highest at 71.2%; The later re-test pass rate is lowest at 4.7% — the gap is 66.4 percentage points.

higher = larger sharecompare shares in percentage points

Failing is usually a same-week event, not a disaster. Of 697 failures followed through to their re-test, 24.1% were repaired and passed the same day and 71.16% within ten days; the median gap is 1 day. 1,102 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 0.124 failures per 10,000 miles, on a median of 5,890 miles a year across 2,331 chains. This is the number to compare between models — an annual rate quietly rewards cars that barely leave the drive.

Odometer anomalies: 0.128% of 2,341 chains show a reading lower than the previous test, with a median drop of 23,769 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.

Porsche Taycan safety recalls and how to check yours

DVSA recall campaigns stand out at 21.

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

recall campaigns launched per year

DVSA lists 21 safety recall campaigns for the Porsche Taycan, covering roughly 57,556 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.

Porsche Taycan technical service bulletins: what dealers are told

NHTSA manufacturer communications are 1,231.

bigger number = more recorded dealer communicationsnot affected vehicles or confirmed faults

These are the issues the manufacturer fixes quietly: service communications sent to dealers without a public recall campaign. They show what the service network has been told even when the issue never became news.

United States · NHTSA manufacturer communications

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.

Porsche Taycan owner complaints: what goes wrong

Lamps & electrical are highest at 129; Steering is lowest at 9 — the gap is 120.

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

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.

US owners have filed 243 complaints about the equivalent Porsche Taycan to the National Highway Traffic Safety Administration, including 7 that mention a crash, 5 a fire and 3 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.

Porsche Taycan inspection results in other countries

Norway PKK is well below the reference at 9.7%, against 33.7% nationally.

higher = larger sharecompare shares in percentage points

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.

Britain is not the only country that inspects every car every year, and the Porsche Taycan 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 Taycan MOT: quick answers

Porsche Taycan MOT Risk Index is well below the reference at 73.0, 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 Porsche Taycan first-time MOT pass rate?

90.78% of first attempts passed in 2024 (6,213 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 9.22% figure is the first-time initial failure rate, using 6,213 primary tests as the denominator (first-time, excluding retests). The age-adjusted MOT initial-failure ratio 73.0 is shown separately because raw rates compare fleet age as well as cars.
