In 2025, 116,859 Citroën C4 cars had a regular MOT in Great Britain. 58% passed first time, compared with 68% for all cars of the same ages, which makes the C4 worse than average. Adjusted for age, it ranks 212 of the 217 most-tested car models.
That comparison matters: older cars fail more often, so a raw pass rate flatters models that are mostly young. We compare each model against every car on the road at the same age.
Pass rate by age
At 6 years old, 77% of C4s passed first time (all cars that age: 84%). By 20 years, that figure is 55% (all cars: 58%). It trails the average car at most ages, most noticeably at 15 years (12 points behind).

| A suspension pin, bush or joint excessively worn | Suspension | 8.1% |
| The aim of a headlamp is not within limits laid down in the requirements | Lights and electrics | 6.8% |

What to check when buying a used C4
Based on where the C4 fails more often than other cars, these are the checks worth making before you buy:
- Body and structure: Get underneath with a torch: sills, jacking points, subframe mounts and floor pans. Structural rust is the failure that can make a car uneconomic to fix. Repair guide
- Steering: Feel for play or knocking through the wheel, and check power-steering fluid isn’t leaking. More
- Lights and electrics: Walk round with the lights on: headlights (dipped and main), indicators, brake lights, number-plate and fog lights. Bulbs are cheap, but a seller who hasn’t noticed one out may have missed more. Repair guide
Then check the individual car: its own MOT history will show whether it follows the pattern. A car with repeated advisories in the same weak area is more likely to fail its next test.
