2018 Ford Chausson — MOT failures & pass rate
Across 1,335 MOT tests, the 2018 Ford Chausson recorded a 95.2% pass rate. That is 6.3 percentage points better than all cars of a similar age, which fail at 11.1%. Failures cluster in lighting & signalling, visibility and tyres.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 8.6% of tests against 1.2% for the next-worst category.
At component level the recurring items are stop lamp, headlamp aim and outline marker lamp — stop lamp alone was recorded 50 times.
The trend is worsening — 3.2% of tests failed in 2021 against 7.4% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2018 Chausson
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 8.6% of tests. Start there.
- Lighting & signalling (8.6% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (1.2% 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.
- Tyres (0.6% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
