2025 MOT results
Peugeot Horizon common problems
The most common reason a Peugeot Horizon fails its MOT is a split joint boot, on 23.3% of its 2,606 failed tests in 2025. Against other cars of the same age, 5 faults stand out, the widest gaps being: a split joint boot at 23.3% of failures against 3.3% expected; an exhaust leak at 6.0% of failures against 1.6% expected; a sidelight out at 13.2% of failures against 4.7% expected.

What fails a Peugeot Horizon MOT
Each bar is the share of failed Peugeot Horizon tests with that defect. Where we can compare it with cars of the same registration years, the marker shows what an average car of those ages records (11 of the 12 items below).
Most common reasons for failure
A test can fail for more than one defect, so shares add up to more than 100%.
| Defect | Share of failed tests |
|---|---|
| Drive shafts: constant velocity boot split or insecure, no longer prevents the ingress of dirt Body, chassis, structure | 23.3% |
| Coil spring: fractured or broken Suspension | 13.7% |
| Stop lamp: not working Lamps, reflectors and electrical equipment | 13.4% |
| Position lamp: not working Lamps, reflectors and electrical equipment | 13.2% |
| Headlamp: not working on dipped beam Lamps, reflectors and electrical equipment | 6.4% |
| Registration plate lamp(s): inoperative in the case of a single lamp or all lamps Lamps, reflectors and electrical equipment | 6.4% |
| Wipers: does not clear the windscreen effectively Visibility | 6.3% |
| Exhaust system: major leak of exhaust gases Body, chassis, structure | 6.0% |
| Brake pads: less than 1.5 mm thick Brakes | 5.4% |
| Tyres: tread depth below requirements of 1.6mm Tyres | 4.3% |
| Individual direction indicators: incorrect colour Lamps, reflectors and electrical equipment | 4.1% |
| Headlamp aim: too high Lamps, reflectors and electrical equipment | 4.0% |

Split joint boot
23.3% of failures 3.3% expected 7.1 times as often
A split rubber boot on a joint or driveshaft. The joint may still be sound, but dirt and water get in once the boot is open.
Turn the wheels to full lock and look behind them for greasy splits in the rubber concertina.
-
Broken coil spring
13.7% of failures 9.2% expected 1.5 times as often
A broken suspension spring, which usually snaps in the bottom coil and often fails on both sides within a year.
Look at each corner for a sagging ride height, and listen for a knock over speed bumps.
-
Brake light out
13.4% of failures 4.8% expected 2.8 times as often
A brake light not working, from a bulb, a poor earth, or the switch on the pedal.
Reverse up to a wall or window at dusk and press the pedal to see all three lamps light.
-
Sidelight out
13.2% of failures 4.7% expected 2.8 times as often
A sidelight, also called a position lamp, not working. It marks the width of the car at night.
Walk round the car with the lights on and the hazards going; these are the cheapest failures to avoid.
-
Headlamp out
6.4% of failures 4.7% expected somewhat more often
A headlamp out on dipped beam, which is the beam the test checks.
Both bulbs age at the same rate, so a pair usually goes within months of each other.
-
Number plate lamp out
6.4% of failures 2.8% expected 2.3 times as often
The lamp over the rear number plate not working, so the plate cannot be read at night.
Walk round the car with the lights on and the hazards going; these are the cheapest failures to avoid.
Which parts of the car fail
Lamps, reflectors and electrical equipment is the area that most often fails a Peugeot Horizon, on 46.7% of failed tests. The widest gap against cars of the same registration years is body, chassis, structure, on 32.8% against 7.3% expected.

What testers warn about
41.8% of Peugeot Horizon tests ended with at least one advisory: a fault the tester found that did not fail the test. On Peugeot Horizons, these are the items to ask about on a car you are viewing, because they are what the last tester expected to go next.
Most common advisories
Share of all tests, passes included.
| Advisory | Share of tests |
|---|---|
| Tread depth: worn close to legal limit or worn on edge Tyres | 11.9% |
| Coil spring: corroded Suspension | 11.0% |
| Tyres: slightly damaged or cracking or perishing Tyres | 7.3% |
| Brake pads: wearing thin Brakes | 5.6% |
| Brake discs: worn, pitted or scored, but not seriously weakened Brakes | 4.8% |
| Engine oil leak, but not excessive Noise, emissions and leaks | 3.9% |
| Suspension arms: pin or bush worn but not resulting in excessive movement Suspension | 3.7% |
| Exhaust system: minor leak of exhaust gases Body, chassis, structure | 2.9% |
| Individual direction indicators: slightly discoloured Lamps, reflectors and electrical equipment | 2.5% |
| Exhaust system: mounting defective Body, chassis, structure | 2.3% |
| Brake discs: worn, but not excessively Brakes | 1.6% |
| Nail in tyre Non-component advisories | 1.4% |

Peugeot Horizon problems: common questions
What is the most common problem with a Peugeot Horizon?
Of the faults that fail an MOT, “Drive shafts: constant velocity boot split or insecure, no longer prevents the ingress of dirt” is the most common: it appears on 23.3% of failed Peugeot Horizon tests. Across categories, lamps, reflectors and electrical equipment is the area that most often fails one, on 46.7% of failed tests.
How often does a Peugeot Horizon fail its MOT?
30.9% of Peugeot Horizon tests in 2025 were not passed first time, from 8,425 tests of cars aged three and over. Allowing for the age and mileage of the cars tested, that gives it a UK Motoring Reliability Score of 40 out of 100, where 50 is as expected.
Does anything fail more often on a Peugeot Horizon than on other cars?
Yes. “Drive shafts: constant velocity boot split or insecure, no longer prevents the ingress of dirt” appears on 23.3% of its failures against 3.3% for cars of the same age, and “Exhaust system: major leak of exhaust gases” appears on 6.0% of its failures against 1.6% for cars of the same age. Where an item is missing from the national figures for a year, we use the smallest share those figures show, so the comparison never overstates the difference.
Are these the same as breakdowns or known faults?
No. These are the items a tester recorded at the MOT, which covers condition and safety: lamps, brakes, tyres, suspension, corrosion and emissions. A gearbox that is unpleasant, an infotainment screen that has died, or a car that will not start on a cold morning are not part of the test, so they are not in these figures.
Where do the figures come from?
Every normal MOT test of a Peugeot Horizon aged three and over in Great Britain in 2025, from DVSA's anonymised MOT results. Retests are excluded, and the same fault on more than one wheel counts once.

Data sources and methodology
| Figures | Source | Period | Records | Updated |

- Shares for defects are of failed tests; shares for advisories are of all tests. A test can carry several defects, so shares add to more than 100%.
- The expected share is what an average car of the same registration years records, weighted by where this model’s failures fall. Where an item is outside the national figures for a year, the smallest share those figures show is used in its place, which is an upper bound, so the comparison never overstates a model’s problems. No expectation is published where less than 80% of the model’s failures can be compared.
- Great Britain only: DVSA does not run MOT testing in Northern Ireland. Cars under three years old are not tested.
- The descriptions of what each part does are general and the same on every model. Every figure comes from the MOT data.
