2024 Toyota Prius — MOT failures & pass rate
645 MOT tests on the 2024 Toyota Prius are in this dataset, and 96.1% of them passed. Small family cars of a similar age fail at 4.4%, so the 2024 Prius sits squarely on the average. Failures cluster in tyres, lighting & signalling and brakes.
What the MOT record shows
No single area dominates — tyres (2.2%) and lighting & signalling (2.0%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, tread depth and rear fog lamp — headlamp aim alone was recorded 6 times.
Condition tracks the odometer closely. Failures run at 2.2% in the 0-30k band and 6.8% in the 60-90k band, a 4.5-point spread — more than double.
Advisories point at the next bill rather than this one: tyres was flagged on 14.7% 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 | 14.7% | 95 |
| 2 | Brakes | 4.0% | 26 |
| 3 | Suspension | 2.0% | 13 |

| 5 | Visibility | 0.9% | 6 |
| 6 | Lighting & signalling | 0.3% | 2 |
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 | 362 | 2.2% |
| 30-60k | 199 | 5.0% |
| 60-90k | 74 | 6.8% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |
|---|---|---|
| 2024 | 279 | 2.5% |
| 2025 | 366 | 4.9% |
What to check before buying a 2024 Prius
On a 2024 Prius, tyres is what the MOT record says goes wrong most — it appeared in 2.2% of tests. Check these areas before you commit.
- Tyres (2.2% 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 (2.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (0.9% 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.
