2015 Toyota Proace — MOT failures & pass rate
7,366 MOT tests on the 2015 Toyota Proace are in this dataset, and 73.7% of them passed. Vans of a similar age fail 21.3% of the time, so this is 5.0pp worse than the group it competes with. Failures cluster in lighting & signalling, body, structure & corrosion and suspension.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 21.2% of tests against 14.1% for the next-worst category.
At component level the recurring items are joints, position lamp and stop lamp — joints alone was recorded 939 times.
Condition tracks the odometer closely. Failures run at 14.9% in the 0-30k band and 28.4% in the 150k+ band, a 13.5-point spread.
Brakes is the most common advisory, noted on 23.7% of tests — work that passed today but is likely due soon.
The trend is worsening — 23.6% of tests failed in 2021 against 28.2% 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 |

| 6 | Visibility | 8.1% | 597 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.

What to check before buying a 2015 Proace
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 21.2% of tests. Start there.
- Lighting & signalling (21.2% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Body, structure & corrosion (14.1% of tests): The one to take seriously on older cars — corrosion to structural areas can be costly and is an MOT failure. Typical repair: £200–£1,500+.
- Suspension (7.4% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
