2014 Toyota Dyna — MOT failures & pass rate
The 2014 Toyota Dyna passed 77.7% of its 274 recorded MOT tests. That is 4.1 percentage points worse than all cars of a similar age, which fail at 18.2%. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
Lighting & signalling dominates the failure mix at 16.4% of all tests — 5.5 points clear of suspension, so it is the first thing to check.
At component level the recurring items are pins and bushes, position lamp and stop lamp — pins and bushes alone was recorded 29 times.
Mileage is the strongest signal on the record: 18.2% of 30-60k cars fail, rising to 26.2% once past 120-150k.
Advisories point at the next bill rather than this one: tyres was flagged on 24.4% of tests without failing them.
The trend is worsening — 22.0% of tests failed in 2021 against 24.0% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2014 Dyna
On a 2014 Dyna, lighting & signalling is what the MOT record says goes wrong most — it appeared in 16.4% of tests. Check these areas before you commit.
- Lighting & signalling (16.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (10.9% 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.
- Brakes (7.7% 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.
