2017 Peugeot Horizon — MOT failures & pass rate
Across 8,152 MOT tests, the 2017 Peugeot Horizon recorded an 85.3% pass rate. That is 2.0 percentage points worse than all cars of a similar age, which fail at 12.7%. Failures cluster in lighting & signalling, body, structure & corrosion and visibility.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 10.0% of tests against 6.6% for the next-worst category.
At component level the recurring items are joints, position lamp and stop lamp — joints alone was recorded 452 times.
Condition tracks the odometer closely. Failures run at 11.2% in the 0-30k band and 23.8% in the 150k+ band, a 12.6-point spread — more than double.
The petrol cars hold up better: 11.6% fail against 14.9% for diesel, a 3.3-point gap across 8,152 tests.
Tyres is the most common advisory, noted on 17.3% of tests — work that passed today but is likely due soon.
The trend is worsening — 10.4% of tests failed in 2021 against 17.6% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2017 Horizon
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 10.0% of tests. Start there.
- Lighting & signalling (10.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Body, structure & corrosion (6.6% 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+.
- Visibility (2.9% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
