2014 BMW X6 — MOT failures & pass rate
Across 7,886 MOT tests, the 2014 BMW X6 recorded an 85.7% pass rate. Large SUVs of a similar age fail at 15.0%, so the 2014 X6 sits squarely on the average. Failures cluster in tyres, lighting & signalling and suspension.
What the MOT record shows
No single area dominates — tyres (6.6%) and lighting & signalling (4.1%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are tread depth, coil spring and washers — tread depth alone was recorded 224 times.
Mileage is the strongest signal on the record: 8.8% of 0-30k cars fail, rising to 19.3% once past 150k — 2.2× the risk.
Advisories point at the next bill rather than this one: tyres was flagged on 24.3% of tests without failing them.

What to check before buying a 2014 X6
On a 2014 X6, tyres is what the MOT record says goes wrong most — it appeared in 6.6% of tests. Check these areas before you commit.
- Tyres (6.6% 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 (4.1% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (3.2% 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.
