2020 Porsche macan — MOT failures & pass rate
The 2020 Porsche macan passed 95.0% of its 11,387 recorded MOT tests. Mid-size SUVs of a similar age fail 8.8% of the time, so this is 3.8pp better than the group it competes with. Failures cluster in tyres, lighting & signalling and brakes.
What the MOT record shows
No single area dominates — tyres (3.7%) and lighting & signalling (1.0%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are tread depth, headlamp aim and brake pads — tread depth alone was recorded 192 times.
Mileage matters less than usual here: the 2020 macan fails 4.3% of the time in the 0-30k band and 7.6% at 60-90k, a spread of only 3.3 points.
Tyres is the most common advisory, noted on 15.7% of tests — work that passed today but is likely due soon.
The trend is worsening — 0.0% of tests failed in 2022 against 5.5% 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.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Tyres | 15.7% | 1,788 |
| 2 | Brakes | 4.6% | 527 |
| 3 | Other defects | 4.3% | 485 |
| 4 | Visibility | 1.8% | 210 |
| 5 | Suspension | 1.2% | 140 |
| 6 | Lighting & signalling | 0.3% | 36 |
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 | 6,517 | 4.3% |
| 30-60k | 4,474 | 5.7% |
| 60-90k | 367 | 7.6% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |

| 2022 | 84 | 0.0% |
| 2023 | 3,768 | 5.0% |
| 2024 | 3,720 | 4.5% |

What to check before buying a 2020 macan
The failure pattern for this year is specific enough to inspect against: tyres accounted for 3.7% of tests. Start there.
- Tyres (3.7% 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 (1.0% 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.
