2011 Toyota Dyna — MOT failures & pass rate
The 2011 Toyota Dyna passed 74.7% of its 478 recorded MOT tests. That is 2.3 percentage points worse than all cars of a similar age, which fail at 23.0%. Failures cluster in lighting & signalling, brakes and suspension.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 21.1% of tests against 14.6% for the next-worst category.
At component level the recurring items are rear fog lamp, service brake performance and tread depth — rear fog lamp alone was recorded 37 times.
Mileage is the strongest signal on the record: 20.0% of 30-60k cars fail, rising to 31.3% once past 150k.
Suspension is the most common advisory, noted on 34.3% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 27.9% in 2021 to 25.3% 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 | Suspension | 34.3% | 164 |
| 2 | Tyres | 24.3% | 116 |
| 3 | Brakes | 21.6% | 103 |
| 4 | Other defects | 15.5% | 74 |
| 5 | Emissions & environmental | 15.1% | 72 |
| 6 | Lighting & signalling | 13.4% | 64 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 30-60k | 40 | 20.0% |
| 60-90k | 100 | 26.0% |
| 90-120k | 122 | 22.9% |
| 120-150k | 109 | 26.6% |
| 150k+ | 96 | 31.3% |
Failure rate by age

What to check before buying a 2011 Dyna
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 21.1% of tests. Start there.
- Lighting & signalling (21.1% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (14.6% 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.
- Suspension (11.5% 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.
