Porsche Rate After Allowing For Vehicle Age
The recorded comparison uses the test results as supplied. The adjusted rate allows for differences in vehicle age.
What this does not tell you: manufacturer statistics describe groups of recorded tests. They cannot prove whether one Porsche is reliable or predict its next MOT result.
Porsche MOT Results Compared With Other Manufacturers
Porsche ranked 1 of 37 after applying the same Great Britain vehicle-age profile to every qualifying manufacturer. This reduces the effect of one manufacturer having an older or newer mix of vehicles.

Common Porsche MOT Faults
These are the most frequently recorded specific failure items in the 2025 Porsche data. The percentages are shares of recorded failure items, not shares of tests. A failed test can contain more than one item.
Porsche Model MOT Pass Rates
6 models met the minimum of 5,000 Class 4 tests. Class 4 covers cars, taxis and certain light commercial vehicles, so qualifying model tables may include vans. The table is ordered by outright first-time pass rate. These model rates are not age-adjusted, so different age profiles can affect the comparison.
MACAN recorded the highest rate in this qualifying set at 91.3% across 36,846 tests. BOXSTER recorded the lowest at 84.4% across 35,878 tests. This is a historical MOT comparison, not a prediction for every example of either model.

Porsche MOT Results And Reliability FAQs
Does an MOT pass rate measure reliability?
It is one reliability indicator. The 2025 Class 4 data shows how Porsche vehicles performed at MOT tests. It does not measure breakdowns, durability, repair costs or the condition of one vehicle.
What does passed first time mean?
An outright first-time pass means the initial recorded test result was a pass, before any repair at the test station or retest.
Which Porsche model had the highest MOT pass rate?
MACAN recorded the highest outright first-time rate among qualifying models at 91.3%. Only models with at least 5,000 tests are included, and these model results are not age-adjusted.
Can I check a Porsche's MOT history for free?
Yes. The free MOT history can show recorded passes, failures, advisories and mileage from official MOT records for the registration you enter.
What does the Premium Vehicle Report add?
It adds available checks for outstanding finance, stolen records, write-off and salvage history, mileage, recalls, valuation and other vehicle data for the individual registration.
