2015 Subaru Xv — MOT failures & pass rate
Across 3,639 MOT tests, the 2015 Subaru Xv recorded an 86.7% pass rate. Against small SUVs of a similar age (16.5% fail rate), the 2015 Xv comes out 3.2pp better. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
No single area dominates — lighting & signalling (6.2%) and suspension (5.1%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are pins and bushes, brake pads and wipers — pins and bushes alone was recorded 130 times.
Mileage is the strongest signal on the record: 7.1% of 0-30k cars fail, rising to 18.1% once past 120-150k — 2.6× the risk.
The petrol cars hold up better: 12.0% fail against 14.5% for diesel, a 2.6-point gap across 3,634 tests.
Brakes is the most common advisory, noted on 20.6% of tests — work that passed today but is likely due soon.
The trend is worsening — 8.8% of tests failed in 2021 against 18.9% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2015 Xv
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 6.2% of tests. Start there.
- Lighting & signalling (6.2% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- 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.
- Brakes (4.3% 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.
