2015 Toyota Granvia — MOT failures & pass rate
297 MOT tests on the 2015 Toyota Granvia are in this dataset, and 79.8% of them passed. That is 4.2 percentage points worse than all cars of a similar age, which fail at 16.0%. Failures cluster in lighting & signalling, brakes and suspension.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 14.8% of tests against 6.7% for the next-worst category.
At component level the recurring items are rear fog lamp, shock absorbers and wipers — rear fog lamp alone was recorded 22 times.
Mileage is the strongest signal on the record: 10.0% of 30-60k cars fail, rising to 33.3% once past 150k — 3.3× the risk.
Brakes is the most common advisory, noted on 25.9% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 21.1% in 2021 to 13.6% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 2015 Granvia
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 14.8% of tests. Start there.
- Lighting & signalling (14.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (6.7% 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.
- Suspension (5.1% 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.
