2012 Toyota Dyna — MOT failures & pass rate
281 MOT tests on the 2012 Toyota Dyna are in this dataset, and 77.6% of them passed. That is 1.0 percentage points worse than all cars of a similar age, which fail at 21.4%. Failures cluster in lighting & signalling, brakes and suspension.
What the MOT record shows
Lighting & signalling dominates the failure mix at 14.6% of all tests — 3.2 points clear of brakes, so it is the first thing to check.
At component level the recurring items are service brake performance, position lamp and tread depth — service brake performance alone was recorded 22 times.
A 150k+ example is materially riskier than a 90-120k one: 20.9% versus 28.6%.
Advisories point at the next bill rather than this one: suspension was flagged on 26.7% of tests without failing them.
The trend is improving — the fail rate fell from 23.5% in 2021 to 20.9% in 2025, as the worst-kept examples leave the fleet.

Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.

| 90-120k | 105 | 28.6% |
| 120-150k | 72 | 22.2% |
| 150k+ | 43 | 20.9% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |

What to check before buying a 2012 Dyna
On a 2012 Dyna, lighting & signalling is what the MOT record says goes wrong most — it appeared in 14.6% of tests. Check these areas before you commit.
- Lighting & signalling (14.6% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (11.4% 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 (10.0% 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.
