Peugeot Horizon MOT pass rate & common failures
Across 16 model years and 50,286 tests, the Peugeot Horizon passes its MOT 82.8% of the time. All cars of a similar age fail 15.0% of the time, so this is 2.2pp worse than the group it competes with. Its most common failure areas are lighting & signalling, body, structure & corrosion and suspension.
Best and worst Horizon years
Ranked across Horizon years with at least 1,000 tests. Older cars fail more simply because they are older — compare years close together in age before drawing conclusions.
What the MOT record shows
Build year matters more than the headline suggests: 2019 cars pass 88.5% of the time while 2013 cars manage 77.3%, a 11.2-point spread.
No single area dominates — lighting & signalling (10.6%) and body, structure & corrosion (7.8%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are joints, stop lamp and position lamp — joints alone was recorded 3,127 times.
Condition tracks the odometer closely. Failures run at 12.1% in the 0-30k band and 27.1% in the 150k+ band, a 15.0-point spread — more than double.
The petrol cars hold up better: 15.2% fail against 17.5% for diesel, a 2.3-point gap across 50,286 tests.
Tyres is the most common advisory, noted on 18.2% of tests — work that passed today but is likely due soon.
The trend is worsening — 13.9% of tests failed in 2021 against 19.5% in 2025, the usual pattern as a fleet ages.

What to check before buying a Peugeot Horizon
- Lighting & signalling (10.6% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Body, structure & corrosion (7.8% of tests): The one to take seriously on older cars — corrosion to structural areas can be costly and is an MOT failure. Typical repair: £200–£1,500+.
- Suspension (4.5% 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.
