2014 Ford B Max — MOT failures & pass rate
Across 78,122 MOT tests, the 2014 Ford B Max recorded an 82.9% pass rate. MPVs of a similar age fail 19.1% of the time, so this is 2.0pp better than the group it competes with. Failures cluster in lighting & signalling, tyres and suspension.
What the MOT record shows
Lighting & signalling dominates the failure mix at 11.8% of all tests — 6.3 points clear of tyres, so it is the first thing to check.
At component level the recurring items are stop lamp, ball joint and wipers — stop lamp alone was recorded 6,656 times.
Mileage is the strongest signal on the record: 9.1% of 0-30k cars fail, rising to 27.7% once past 150k — 3.0× the risk.
Split by fuel, diesel examples fail 6.9pp more often than petrol ones (22.6% vs 15.8%) — worth weighing if you have a choice.
Advisories point at the next bill rather than this one: tyres was flagged on 27.6% of tests without failing them.
The trend is worsening — 13.7% of tests failed in 2021 against 20.1% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2014 B Max
On a 2014 B Max, lighting & signalling is what the MOT record says goes wrong most — it appeared in 11.8% of tests. Check these areas before you commit.
- Lighting & signalling (11.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Tyres (5.5% 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.
- Suspension (5.2% 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.
