2012 BMW X6 — MOT failures & pass rate
The 2012 BMW X6 passed 83.3% of its 6,418 recorded MOT tests. Large SUVs of a similar age fail 17.8% of the time, so this is 1.0pp better than the group it competes with. Failures cluster in suspension, tyres and lighting & signalling.
What the MOT record shows
No single area dominates — suspension (7.0%) and tyres (5.8%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are coil spring, side repeaters and tread depth — coil spring alone was recorded 313 times.
Mileage matters less than usual here: the 2012 X6 fails 13.0% of the time in the 30-60k band and 16.5% at 150k+, a spread of only 3.5 points.
Advisories point at the next bill rather than this one: tyres was flagged on 24.3% of tests without failing them.
The trend is worsening — 15.8% of tests failed in 2021 against 17.6% in 2025, the usual pattern as a fleet ages.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |

What to check before buying a 2012 X6
On a 2012 X6, suspension is what the MOT record says goes wrong most — it appeared in 7.0% of tests. Check these areas before you commit.
- Suspension (7.0% 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.
- Tyres (5.8% 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 (5.4% 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.
