Used buying checklist
Citroen C1 reliability, common problems and used buying checks
A used Citroen C1 looks about average for reliability in UK MOT data: 18.7% of 204,200 tests failed, compared with 18.7% across all indexed models. A good example should have a clean MOT history for corrosion and structure, lights and electrical, and emissions, engine, and exhaust.
It can be, if the exact car has a clean history for corrosion and structure, lights and electrical, and emissions, engine, and exhaust.
Start with corrosion and structure, lights and electrical, and emissions, engine, and exhaust, then compare the car's mileage and recall record below.

Should you buy a used Citroen C1?
81.3% of the MOT tests we analysed for this model passed. The model's recorded failure rate is 18.7%, -0.0 percentage points compared with the average across all models. This is a buying brief for the exact car in front of you: clean repeat history matters more than badge reputation.
- Repeat unresolved MOT notes for corrosion and structure, lights and electrical, and emissions, engine, and exhaust
- corrosion and structure appearing across more than one MOT
- Any dangerous MOT failure on the exact car, especially if the same area appears again later
- No paperwork showing applicable recall work has been completed
- A seller who cannot explain MOT wording such as "corroded so that its cross sectional area is reduced and seriously weakened"
It can be, if the exact car has a clean history for corrosion and structure, lights and electrical, and emissions, engine, and exhaust.
Start with corrosion and structure, lights and electrical, and emissions, engine, and exhaust, then compare the car's mileage and recall record below.
Corrosion and structure is the clearest named problem area in the MOT history (41.1 MOT notes per 100 tests). These counts are issue notes, not failure rates, because a single MOT can list several faults.
Past 100k miles on the Citroen C1, MOT records most often point to corrosion and structure, lights and electrical, and emissions, engine, and exhaust.
The MOT failure rate rises from 5.2% at 0-3 years to 28.6% at 15+ years. Compare the car with the nearest age range before treating a fault as normal wear or a warning sign. The average MOT failure rate across all models in the same dataset is 18.7%.
Start with corrosion and structure, lights and electrical, emissions, engine, and exhaust, and windscreen, wipers, and mirrors. The checklist on this page explains why each area is being recommended, what to inspect, and what to ask the seller.
6 relevant recall notices appear for this model. Treat them as safety checks to verify for the exact car, not as normal MOT wear.

Recall records and data freshness
Recall context: are there safety notices to know about?
6 relevant recall notices appear for this model. Treat them as safety checks to verify for the exact car, not as normal MOT wear.
| 2020-12-02 | THE STITCHING PATTERN USED ON THE REAR SEAT BELT MATERIAL IS NOT TO CORRECT SPECIFICATION On affected vehicles some rear seat belts may have incorrect stitching on the belt material to connect the buckle to the anchor plate. Check seat belts and relace if necessary. |
|---|---|
| 2018-12-12 | THE BONDING OF THE REAR DOOR WINDOW GLASS TO THE HINGE ASSEMBLIES MAY NOT CONFORM TO SPECIFICATION On the affected vehicles the bonding of the rear door window glass to the hinge assemblies may not conform to specification. Check and if necessary replace the rear window or re- bond the rear window glass hinges. |
| 2016-06-27 | STEERING COLUMN MAY FAIL UNEXPECTEDLY A component of the steering column may not be to specification and could fail. If this occurs there would be a loss of directional control. The manufacturer will contact keepers of affected vehicles and advise not to use the vehicle. Examine vehicles and on those with the affected component replace the steering column. |
| 2015-01-30 | BUMPER MAY NOT PERFORM AS DESIGNED IN A COLLISION Affected vehicles may have a small defect in the front bumper frame. This may affect its impact absorption in the even of a collision. If required replace front bumper frame. |
| 2014-12-19 | LOSS OF CONTROL The front shock absorber rod may have an internal fault which could cause it to brake. This could have an adverse affect on the front suspension and the driver's ability to control the vehicle. On affected vehicles replace both front shock absorbers. |
| 2014-02-25 | REAR CROSS-MEMBER MAY FAIL AND CAUSE DRIVER TO LOSE CONTROL On subject vehicles a weld on the rear cross member might be non-compliant and eventually cause the weld between the cross member and the vehicle body to break. This may lead to a partial detachment of the axle and cause the driver to lose control. Contact keepers using DVLA and manufacturer's records. Check the compliance of the weld on the O/S/R and if necessary replace the cross member. |
