Is the Horizon getting worse?
The fail rate rose 5.8 points to 23.9% from 2022 to 2025 while the median one tested aged 3 years. Ageing alone would predict about 7.5 points, so it is holding up better than the fleet average for its age.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 8,511 | 6 | 18.1% | 22.5% | |
| 2023 | 8,573 | 7 | 21.2% | 22.8% | |
| 2024 | 7,247 | 8 | 23% | 23.2% | |
| 2025 | 7,744 | 9 | 23.9% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Horizon at its test that year, and it is the number to watch: across the whole fleet each extra year of age adds roughly 1.9 points to the fail rate, so a model whose age and fail rate rise together is simply getting older.
The exact defects that fail it
Every failure item DVSA recorded against a Horizon in 2025, counted by how many tests each one appeared on.
- 1Joints: constant velocity boot split or insecure, no longer prevents the ingress of dirt477 tests
- 2Coil spring: fractured or broken330 tests
- 3Stop lamp: not working224 tests
- 4Position lamp: not working201 tests
- 5Exhaust system: has a major leak of exhaust gases144 tests
- 6Brake pads: less than 1.5 mm thick123 tests
- 7Registration plate lamp(s): inoperative in the case of a single lamp or all lamps108 tests
- 8Wipers: does not clear the windscreen effectively106 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical Horizon collects 2.38 of them per test, and these are the ones that come up most. Treat it as the running-repairs list for the next year or two.
- 1Coil spring: corroded so that its cross sectional area is reduced and seriously weakened847 tests
- 2Tread depth: tread depth below requirements of 1.6mm829 tests
- 3Condition: has a tear, caused by separation or partial failure of its structure553 tests
- 4Brake pads: less than 1.5 mm thick427 tests
- 5Brake discs: in such a condition that it is seriously weakened373 tests
- 6Engine oil leaks: leaking excessively from engine310 tests
- 7Pins and bushes: pin or bush excessively worn301 tests
- 8Exhaust system: has a major leak of exhaust gases218 tests

What does a Peugeot Horizon usually fail on?
The single most common failure is "Joints: constant velocity boot split or insecure, no longer prevents the ingress of dirt", recorded on 477 failed tests, followed by "Coil spring: fractured or broken" and "Stop lamp: not working". By section, lamps, reflectors and electrical equipment appears in 38.2% of failures, body, chassis, structure appears in 37% of failures, suspension appears in 30.9% of failures.
Does age change the odds?
Sharply. At 3 to 5 years old the fail rate was 12.2%; at 10-13 years it was 29.4%. The median Peugeot Horizon tested in 2025 was 9 years old with 41,702 miles.
Is the Peugeot Horizon getting less reliable?
The fail rate rose 5.8 points to 23.9% from 2022 to 2025 while the median one tested aged 3 years. Ageing alone would predict about 7.5 points, so it is holding up better than the fleet average for its age.
