Used buying checklist
Citroen C8 reliability, common problems and used buying checks
A used Citroen C8 looks worse than average for reliability in UK MOT data: 33.8% of 1,815 tests failed, compared with 18.7% across all indexed models. A good example should have a clean MOT history for corrosion and structure, suspension and steering, and emissions, engine, and exhaust.
It can be, if the exact car has a clean history for corrosion and structure, suspension and steering, and emissions, engine, and exhaust.
Start with corrosion and structure, suspension and steering, and emissions, engine, and exhaust, then compare the car's mileage and recall record below.

Should you buy a used Citroen C8?
66.2% of the MOT tests we analysed for this model passed. The model's recorded failure rate is 33.8%, +15.1 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, suspension and steering, 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, suspension and steering, and emissions, engine, and exhaust.
Start with corrosion and structure, suspension and steering, 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 (54.4 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 C8, MOT records most often point to corrosion and structure, suspension and steering, and emissions, engine, and exhaust.
The MOT failure rate rises from 34.4% at 10-15 years to 33.7% 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, suspension and steering, emissions, engine, and exhaust, and lights and electrical. 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.
| 2015-12-08 | FUEL MAY LEAK The fuel filter's integrated heater may be defective and could cause the cover to distort. This could cause air ingress and fuel egress. Either could cause poor starting and a warning light should illuminate On affected vehicles replace fuel heater cover. Check and if necessary replace connector. |
|---|---|
| 2013-09-02 | LOSS OF STEERING The steering column to steering wheel shaft may not have been assembled correctly. If not corrected noise and play will become apparent and if these warnings are not acted on eventually steering control could be lost. Recall the vehicles that are likely to be affected to check and where necessary refit the steering column correctly to the steering wheel shaft. |
| 2012-03-28 | TYRE MAY DEFLATE Some tyres may have suffered superficial damage when the vehicle was being transported. The front Left hand tyre may have localised damage on the tread or the inner side. The tyre may rip and deflate. Carry out a visual check of the condition of the tyre in the affected areas and replace the tyre if necessary. |
| 2011-07-11 | POWER STEERING ASSISTANCE MAY FAIL It is possible that the wiring harness for the power assisted steering motor may come in contact with other components in the engine bay. Should this occur then it is possible that the power steering assistance on this large vehicle may become affected. Recall affected vehicles and fit protection to the wiring harness. |
| 2010-10-05 | LIGHTS MAY FAIL WITHOUT WARNING It has been identified that the position of the exterior lighting control ring may not be detected by the lighting management system and the lights may switch off without warning. Recalled vehicles will have the lighting management software updated. |
| 2010-08-09 | BRAKING EFFICIENCY MAY BE COMPROMISED The threaded portion of the brake linkage rod in the brake control system may not be to conformity. This could result in a reduction of braking efficiency. Recall affected vehicles to check rod and replace if found not to meet conformity. |
