2019 Porsche Cayenne — MOT failures & pass rate
13,022 MOT tests on the 2019 Porsche Cayenne are in this dataset, and 94.4% of them passed. Large SUVs of a similar age fail 9.8% of the time, so this is 4.2pp better than the group it competes with. Failures cluster in tyres, lighting & signalling and brakes.
What the MOT record shows
Tyres dominates the failure mix at 4.0% of all tests — 3.3 points clear of lighting & signalling, so it is the first thing to check.
At component level the recurring items are tread depth, registration plates and headlamp aim — tread depth alone was recorded 112 times.
Mileage matters less than usual here: the 2019 Cayenne fails 4.5% of the time in the 0-30k band and 6.7% at 90-120k, a spread of only 2.2 points.
Fuel type barely separates them — hybrid fails 5.4% of the time against 5.7% for petrol.
Advisories point at the next bill rather than this one: tyres was flagged on 16.5% of tests without failing them.
The trend is worsening — 3.1% of tests failed in 2021 against 6.8% in 2025, the usual pattern as a fleet ages.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.

What to check before buying a 2019 Cayenne
On a 2019 Cayenne, tyres is what the MOT record says goes wrong most — it appeared in 4.0% of tests. Check these areas before you commit.
- Tyres (4.0% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
- Lighting & signalling (0.7% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (0.7% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
