MOT pass rates / Porsche
Porsche MOT pass rates and common failures
Porsche cars passed 86.6% of their MOTs first time in 2024, across 142,110 class-4 initial tests and 7 model groups. That is above the 71.2% UK average, and ranks Porsche 8th of 59 makes in the dataset.
Pass rates track age more strongly than badge: an older Porsche is compared here against older cars of every other make, so read the age table below before drawing conclusions about the brand.

What Porsche cars fail on
The items most often behind a first-test failure across Porsche model groups, as a share of Porsche tests. DVSA publishes each model group's six most common categories, so this ranks the biggest published causes rather than every possible one.
- Condition — 2.5% of Porsche tests. Corrosion, damage or wear on a tested component. Worth seeing in person, as the cost ranges from trivial to structural.
- Exhaust Emissions — 2% of Porsche tests. The car exceeded its emissions limits. Can be a sensor or a service, but on a diesel it can also mean an expensive filter or catalyst.
- Headlamp Aim — 1.8% of Porsche tests. Headlights pointing too high or low. Cheap to adjust, and common on every make.
- Springs — 0.8% of Porsche tests. A broken or sagging coil spring. Replaced in pairs, so it is not the cheapest failure.
- Tread Depth — 0.7% of Porsche tests. Tyres below the 1.6mm legal limit. Budget for tyres, and treat it as a sign of how the car was maintained.
- Rigid Brake Pipes — 0.7% of Porsche tests. Corroded brake pipes. Safety-critical and a sign of underbody corrosion.
- Transmission — 0.5% of Porsche tests. A fault with a driveshaft, gaiter or transmission component. Costs vary widely.
- Brake Performance — 0.5% of Porsche tests. The brakes underperformed on the rolling road. Expect brake work rather than an adjustment.

Common questions
What is the Porsche MOT pass rate?
86.6% of 142,110 class-4 initial MOT tests on Porsche cars passed first time in 2024 — above the 71.2% UK average across all published models.
Which Porsche has the best MOT pass rate?
Of the Porsche model groups with a substantial sample, the Macan has the highest initial pass rate at 90.8% across 28,528 tests. Pass rates track vehicle age closely, so newer model groups tend to sit higher.
Does a good Porsche pass rate mean the car I am looking at is fine?
No. A model-level rate describes a population, not one vehicle. Enter the registration for that car's own MOT, tax and mileage record, and check for outstanding finance, write-off and stolen markers before you buy.
Methodology and limitations
MOT outcomes describe testable items at the time of inspection. They are not a measure of overall mechanical reliability.
Scope: Class 4 normal initial MOT tests completed in 2024. Models require at least 1,000 qualifying tests. Duplicate source rows are removed using official DVSA test IDs.
Source: Driver and Vehicle Standards Agency anonymised MOT tests and results, 2024, published 2025-05-23 under the Open Government Licence v3.0.
