About the Porsche Cayenne

The Porsche Cayenne was MOT tested 80,646 times in 2024 (DVSA data, retests included) across 20 model years (2003 to 2022), with an average pass rate of 90%. That's comfortably above the average of 82% across all models in our data. Our records list petrol and diesel and hybrid and lpg and electric versions.

Best and Worst Years

Of the years with at least 100 tests, the 2020 model has the highest pass rate at 96% from 7,136 tests. The 2007 model has the lowest at 83%. The 13 point gap means pass rates vary somewhat between years, but no year is dramatically different. Newer cars usually pass more often simply because they are younger.

Reliability Trend

Newer Porsche Cayennes pass their MOT more often than older ones, by 7 percentage points on average, which is mostly down to age and wear.

Mileage Across Years

The oldest model in our data (2003) averages 121,522 miles, while the newest (2022) averages 24,282 miles. Older models have covered serious mileage, so suspension and drivetrain wear are worth checking.
