2020 Porsche Cayenne S E-Hybrid — MOT failures & pass rate
534 MOT tests on the 2020 Porsche Cayenne S E-Hybrid are in this dataset, and 94.0% of them passed. That is 3.3 percentage points better than all cars of a similar age, which fail at 9.3%. Failures cluster in tyres, visibility and brakes.
What the MOT record shows
One area stands out: tyres, recorded in 4.5% of tests against 0.9% for the next-worst category.
At component level the recurring items are tread depth, headlamp aim and washers — tread depth alone was recorded 9 times.
Tyres is the most common advisory, noted on 15.2% of tests — work that passed today but is likely due soon.
The trend is worsening — 4.6% of tests failed in 2023 against 7.1% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2020 Cayenne S E-Hybrid
The failure pattern for this year is specific enough to inspect against: tyres accounted for 4.5% of tests. Start there.
- Tyres (4.5% 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.
- Visibility (0.9% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
- Brakes (0.6% 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.
