2020 SEAT Ateca — MOT failures & pass rate
25,734 MOT tests on the 2020 SEAT Ateca are in this dataset, and 92.4% of them passed. Small SUVs of a similar age fail at 7.9%, so the 2020 Ateca sits squarely on the average. Failures cluster in tyres, lighting & signalling and brakes.
What the MOT record shows
No single area dominates — tyres (3.6%) and lighting & signalling (1.9%) 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 620 times.
A 90-120k example is materially riskier than a 0-30k one: 12.9% versus 5.3%.
Fuel type barely separates them — petrol fails 7.5% of the time against 8.4% for diesel.
Advisories point at the next bill rather than this one: tyres was flagged on 22.7% of tests without failing them.
The trend is worsening — 3.7% of tests failed in 2022 against 8.8% 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.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Tyres | 22.7% | 5,838 |
| 2 | Brakes | 13.0% | 3,341 |

| 5 | Visibility | 2.4% | 616 |
| 6 | Lighting & signalling | 0.3% | 67 |
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 | 12,862 | 5.3% |
| 30-60k | 11,451 | 9.7% |

What to check before buying a 2020 Ateca
On a 2020 Ateca, tyres is what the MOT record says goes wrong most — it appeared in 3.6% of tests. Check these areas before you commit.
- Tyres (3.6% 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 (1.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (1.6% 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.
