2020 Porsche Panamera — MOT failures & pass rate
The 2020 Porsche Panamera passed 92.3% of its 763 recorded MOT tests. Executive cars of a similar age fail 10.0% of the time, so this is 2.2pp better than the group it competes with. Failures cluster in tyres, brakes and lighting & signalling.
What the MOT record shows
Tyres dominates the failure mix at 7.0% of all tests — 6.4 points clear of brakes, so it is the first thing to check.
At component level the recurring items are tread depth, tyre pressure monitoring system and registration plates — tread depth alone was recorded 10 times.
Mileage is the strongest signal on the record: 6.3% of 0-30k cars fail, rising to 17.0% once past 60-90k — 2.7× the risk.
Advisories point at the next bill rather than this one: tyres was flagged on 17.4% of tests without failing them.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Tyres | 17.4% | 133 |
| 2 | Brakes | 5.2% | 40 |
| 3 | Other defects | 4.1% | 31 |

| 5 | Road wheels | 0.7% | 5 |
| 6 | Emissions & environmental | 0.4% | 3 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 0-30k | 416 | 6.3% |
| 30-60k | 292 | 8.6% |
| 60-90k | 47 | 17.0% |
Failure rate by age
By fuel type
| Fuel | Tests | Fail rate |
|---|---|---|
| Petrol | 427 | 5.9% |
| Hybrid | 336 | 10.1% |
Trend over time
| Dataset year | Tests | Fail rate |
|---|---|---|
| 2023 | 249 | 6.8% |
| 2024 | 255 | 9.8% |

What to check before buying a 2020 Panamera
On a 2020 Panamera, tyres is what the MOT record says goes wrong most — it appeared in 7.0% of tests. Check these areas before you commit.
- Tyres (7.0% 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.
- Brakes (0.5% 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.
- Lighting & signalling (0.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
