The 2017 Porsche Cayenne is a solid performer on MOT, passing first time at 90.9%—a solid 10.9 points ahead of the UK average—though one concern is that 21.1% of these vehicles have recorded a dangerous defect at some point, which is elevated and worth investigating in any used example you're considering. Diesel and petrol variants are evenly matched (91.0% and 91.9% pass rates respectively), with hybrids slightly lower at 90.0%.

These Cayennes are running around 50,700 miles on average for their age, which is typical mileage, and they average 0.69 failures per test—suggesting that when things do go wrong, they're usually minor. The real issue is advisories: at 4.8 per vehicle, these cars tend to accumulate wear-related issues, so budget for routine maintenance and always get a pre-purchase inspection focused on suspension, brakes, and cooling systems where older Cayennes commonly rack up advisory flags.

The 2017 Porsche Cayenne passes its MOT first time at roughly the UK average rate (91%) — solid but worth checking this vehicle's history carefully.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context
Good baseline reliability. A 91% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.
🔧 Expect consumable spend. An average of 4.8 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.
🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 2,021 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
