2015 Hyundai Ix35 — MOT failures & pass rate
The 2015 Hyundai Ix35 passed 82.7% of its 70,103 recorded MOT tests. That is 1.5 percentage points worse than mid-size SUVs of a similar age, which fail at 15.8%. Failures cluster in brakes, tyres and lighting & signalling.
What the MOT record shows
No single area dominates — brakes (9.4%) and tyres (6.5%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are tread depth, brake pads and rbt (sp) — tread depth alone was recorded 2,745 times.
Condition tracks the odometer closely. Failures run at 8.5% in the 0-30k band and 24.6% in the 150k+ band, a 16.1-point spread — more than double.
Fuel type barely separates them — petrol fails 17.1% of the time against 17.4% for diesel.
Advisories point at the next bill rather than this one: tyres was flagged on 27.3% of tests without failing them.
The trend is worsening — 14.3% of tests failed in 2021 against 20.3% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2015 Ix35
On a 2015 Ix35, brakes is what the MOT record says goes wrong most — it appeared in 9.4% of tests. Check these areas before you commit.
- Brakes (9.4% 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.
- Tyres (6.5% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
- Lighting & signalling (5.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
