Where the Cayenne fails its MOT
Where Porsche Cayenne cars that failed their 2025 MOT were marked down, as a share of all recorded failure items.
The specific items testers recorded most often were coil spring fractured or broken (9%), condition has a cut in excess of the requirements deep enough to reach the ply or cords (6.9%) and tread depth below requirements of 1.6mm (6.4%). See every common Cayenne MOT failure.
These are DVSA failure records across every Porsche Cayenne that failed, not a claim that every Cayenne has these problems.
What should you check when buying a used Cayenne?
The areas above, most common first, and what an MOT tester looks at in each.
1
Lamps, reflectors and electrical equipment
Walk round with every light on: headlights, brake lights, indicators, fog lights and the number plate lamp. Check no warning lights stay on after starting. 23.4% of Cayenne failure items.
2
Tyres
Check tread depth across the full width of every tyre (the legal minimum is 1.6mm), and look for cuts, bulges and uneven wear. 23.2% of Cayenne failure items.
3
Brakes
Make sure the pedal feels firm, the car stops in a straight line, the handbrake holds on a slope and no brake warning light is showing. 13.6% of Cayenne failure items.
4
Suspension
Listen for knocks over bumps, check the car sits level, and look for leaking shock absorbers and split rubber gaiters. 13.4% of Cayenne failure items.
5
Visibility
Check the windscreen for chips or cracks in the driver's view, and that the wipers and washers clear it properly. 7.7% of Cayenne failure items.

What the MOT record doesn't tell you
Knowing Porsche Cayenne failures cluster around lamps, reflectors and electrical equipment and tyres tells you what to inspect. It tells you nothing about whether the car is safe to buy. An MOT does not show money still owed on the car, a write-off, a theft record or a clocked odometer.

Used Porsche Cayenne FAQs
Is the Porsche Cayenne reliable?
MOT data does not measure reliability. It records whether a car met the roadworthiness standard on the day of its test. What it does show is an 85.2% first-time pass rate for the Porsche Cayenne across 31,778 tests in 2025, above the 72.3% average for all cars.
Do older Porsche Cayenne cars fail their MOT more often?
Porsche Cayenne cars aged 3 to 5 years passed 92.1% of MOT tests in 2025; for examples aged 11 years and over that fell to 78.8%. On an older example, the car's own MOT history tells you more than the model average.
What should I check before buying a used Porsche Cayenne?
On the car itself, start with the areas it most often fails on: lamps, reflectors and electrical equipment, tyres and brakes. Then check the individual car's history: outstanding finance, insurance write-off records, stolen markers, mileage and previous keepers. None of these appear in the MOT record or on the V5C.
How do I check a Porsche Cayenne's history?
Enter the registration of the specific car. A Carpeep car history check reports outstanding finance, write-off category, stolen markers, mileage history, previous keepers, MOT and tax status, import and export markers and scrapped status in one £15 report.
MOT figures are aggregated from the DVSA MOT Anonymised data set for 2025 (class 4 initial tests, retests excluded), licensed under the Open Government Licence v3.0. MOT results describe roadworthiness at test, not mechanical reliability.
