2021 Peugeot Horizon — MOT failures & pass rate
Across 813 MOT tests, the 2021 Peugeot Horizon recorded an 89.5% pass rate. All cars of a similar age fail 8.6% of the time, so this is 1.9pp worse than the group it competes with. Failures cluster in visibility, lighting & signalling and tyres.
What the MOT record shows
Visibility dominates the failure mix at 9.3% of all tests — 5.3 points clear of lighting & signalling, so it is the first thing to check.
At component level the recurring items are wipers, headlamp aim and tread depth — wipers alone was recorded 85 times.
Advisories point at the next bill rather than this one: tyres was flagged on 14.4% of tests without failing them.

What to check before buying a 2021 Horizon
On a 2021 Horizon, visibility is what the MOT record says goes wrong most — it appeared in 9.3% of tests. Check these areas before you commit.
- Visibility (9.3% 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 (4.1% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Tyres (3.1% 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.
