2021 Ford Tourneo Custom 320 Tnium — MOT failures & pass rate
Across 2,070 MOT tests, the 2021 Ford Tourneo Custom 320 Tnium recorded an 87.3% pass rate. All cars of a similar age fail 8.4% of the time, so this is 4.3pp worse than the group it competes with. Failures cluster in visibility, lighting & signalling and tyres.
What the MOT record shows
No single area dominates — visibility (6.7%) and lighting & signalling (5.3%) 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 139 times.
Mileage matters less than usual here: the 2021 Tourneo Custom 320 Tnium fails 9.8% of the time in the 0-30k band and 11.5% at 150k+, a spread of only 1.7 points.
Tyres is the most common advisory, noted on 15.6% of tests — work that passed today but is likely due soon.
The trend is worsening — 1.2% of tests failed in 2022 against 13.5% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2021 Tourneo Custom 320 Tnium
The failure pattern for this year is specific enough to inspect against: visibility accounted for 6.7% of tests. Start there.
- Visibility (6.7% 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 (5.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Tyres (4.2% 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.
