Toyota Dyna MOT pass rate & common failures
6,450 MOT tests on the Toyota Dyna (1986–2020) give it a 73.6% pass rate. All cars of a similar age fail 25.3% of the time, so this is 1.1pp worse than the group it competes with. Its most common failure areas are lighting & signalling, brakes and suspension.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 18.1% of tests against 14.2% for the next-worst category.
At component level the recurring items are service brake performance, position lamp and pins and bushes — service brake performance alone was recorded 519 times.
Condition tracks the odometer closely. Failures run at 14.8% in the 0-30k band and 28.1% in the 150k+ band, a 13.3-point spread.
Suspension is the most common advisory, noted on 36.3% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 26.9% 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.

What to check before buying a Toyota Dyna
- Lighting & signalling (18.1% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (14.2% 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 (11.0% 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.
