2021 Toyota Supra Pro — MOT failures & pass rate
The 2021 Toyota Supra Pro passed 95.3% of its 469 recorded MOT tests. Against all cars of a similar age (8.6% fail rate), the 2021 Supra Pro comes out 4.0pp better. Failures cluster in tyres, lighting & signalling and emissions & environmental.
What the MOT record shows
No single area dominates — tyres (3.2%) and lighting & signalling (0.4%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are tread depth, catalyst emissions and headlamp aim — tread depth alone was recorded 5 times.
Tyres is the most common advisory, noted on 16.6% of tests — work that passed today but is likely due soon.

| 5 | Road wheels | 0.4% | 2 |
| 6 | Seat belts & restraints | 0.2% | 1 |
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 | 382 | 3.9% |
| 30-60k | 81 | 8.6% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |
|---|---|---|
| 2024 | 228 | 4.8% |
| 2025 | 232 | 4.3% |
What to check before buying a 2021 Supra Pro
The failure pattern for this year is specific enough to inspect against: tyres accounted for 3.2% of tests. Start there.
- Tyres (3.2% 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 (0.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Emissions & environmental (0.4% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
