1994 Toyota Previa — MOT failures & pass rate
The 1994 Toyota Previa passed 71.9% of its 295 recorded MOT tests. MPVs of a similar age fail 32.1% of the time, so this is 3.9pp better than the group it competes with. Failures cluster in lighting & signalling, visibility and brakes.
What the MOT record shows
No single area dominates — lighting & signalling (12.5%) and visibility (11.2%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are catalyst emissions, wipers and position lamp — catalyst emissions alone was recorded 42 times.
A 150k+ example is materially riskier than a 60-90k one: 32.4% versus 21.3%.
Brakes is the most common advisory, noted on 41.4% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 31.6% in 2021 to 18.9% in 2025, as the worst-kept examples leave the fleet.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Brakes | 41.4% | 122 |
| 2 | Suspension | 35.6% | 105 |
| 3 | Emissions & environmental | 26.4% | 78 |

| 5 | Body, structure & corrosion | 19.3% | 57 |
| 6 | Other defects | 18.6% | 55 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 60-90k | 61 | 21.3% |
| 90-120k | 72 | 29.2% |
| 120-150k | 59 | 27.1% |
| 150k+ | 102 | 32.4% |
Trend over time
| Dataset year | Tests | Fail rate |
|---|---|---|
| 2021 | 95 | 31.6% |
| 2022 | 69 | 31.9% |
| 2023 | 56 | 28.6% |
| 2024 | 38 | 21.1% |
| 2025 | 37 | 18.9% |
What to check before buying a 1994 Previa
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 12.5% of tests. Start there.
- Lighting & signalling (12.5% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (11.2% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
- Brakes (10.8% 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.
