Ford Tourneo Custom 320 Tnium MOT pass rate & common failures
The Ford Tourneo Custom 320 Tnium appears in 7,921 MOT tests spanning model years 2019–2024, and 88.2% of them passed. That is 3.1 percentage points worse than all cars of a similar age, which fail at 8.7%. Its most common failure areas are visibility, lighting & signalling and tyres.
What the MOT record shows
No single area dominates — visibility (5.8%) and lighting & signalling (5.2%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are wipers, headlamp aim and brake pads — wipers alone was recorded 421 times.
Mileage is the strongest signal on the record: 8.6% of 0-30k cars fail, rising to 14.6% once past 150k.
Advisories point at the next bill rather than this one: tyres was flagged on 16.0% of tests without failing them.
The trend is worsening — 3.1% of tests failed in 2021 against 12.8% in 2025, the usual pattern as a fleet ages.

What to check before buying a Ford Tourneo Custom 320 Tnium
- Visibility (5.8% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
- Lighting & signalling (5.2% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Tyres (4.0% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
