2010 Subaru Justy — MOT failures & pass rate
The 2010 Subaru Justy passed 77.6% of its 312 recorded MOT tests. Against all cars of a similar age (24.3% fail rate), the 2010 Justy comes out 1.9pp better. Failures cluster in suspension, lighting & signalling and brakes.
What the MOT record shows
One area stands out: suspension, recorded in 14.4% of tests against 11.2% for the next-worst category.
At component level the recurring items are ball joint, wipers and headlamp aim — ball joint alone was recorded 24 times.
Condition tracks the odometer closely. Failures run at 17.4% in the 30-60k band and 31.8% in the 90-120k band, a 14.5-point spread.
Suspension is the most common advisory, noted on 34.9% of tests — work that passed today but is likely due soon.
The trend is worsening — 17.5% of tests failed in 2021 against 19.6% in 2025, the usual pattern as a fleet ages.

| 30-60k | 144 | 17.4% |
| 60-90k | 104 | 26.0% |
| 90-120k | 44 | 31.8% |

What to check before buying a 2010 Justy
The failure pattern for this year is specific enough to inspect against: suspension accounted for 14.4% of tests. Start there.
- Suspension (14.4% 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.
- Lighting & signalling (11.2% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- 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.
