Based on this data, the Citroen C4 earns a "Average" reliability rating. The average Citroen C4 presents for MOT with approximately 66,316 miles on the clock. Manufacture year matters: 2021 models achieve the highest pass rate at 87.9%, while 2004 models have the lowest at 48.3%. This 39.6 percentage point difference suggests notable variation in build quality or component durability across production years.
The most common MOT failure for the Citroen C4 is Brakes, affecting 28.7% of all tests. Brake-related failures include worn brake pads, corroded brake discs, leaking brake lines, and faulty brake servos. These are safety-critical components — any brake deficiency will result in an MOT fail. The second most common issue is Tyres at 27.4%. Lamps, reflectors and electrical equipment rounds out the top three at 22.3%. Together, these top 3 failure categories account for a significant portion of all MOT failures for this model.

💡 What does the warranty cliff mean?
The Citroen C4 shows a moderate increase in MOT failures after warranty. The 45% increase is typical — plan for gradual maintenance cost increases. Peak failure occurs at age 16 (53.0% fail rate).
Note: pass rates may improve for very old vehicles due to survivorship bias — only well-maintained cars remain on the road.
* High Fail Rate badge indicates an MOT pass rate below 65% (failure rate above 35%).

Use our detailed year-by-year breakdown and failure analysis below to understand how your specific C4 is likely to perform.
Brakes — 28.7% of failures
Brakes issues account for 28.7% of MOT failures on the Citroen C4. Brake-related failures include worn brake pads, corroded brake discs, leaking brake lines, and faulty brake servos. These are safety-critical components — any brake deficiency will result in an MOT fail. Typical repair costs: £150–400. Pre-MOT check: Listen for squealing or grinding noises. Check brake pedal feel — if it feels spongy or goes to the floor, have the system inspected immediately. Look at brake pad thickness through the wheel spokes (minimum 3mm).
Tyres — 27.4% of failures
Tyres issues account for 27.4% of MOT failures on the Citroen C4. Tyre failures include tread depth below the legal minimum of 1.6mm, cuts, bulges, exposed cords, and incorrect tyre pressure. Tyres are one of the most common and easiest-to-prevent MOT failures. Typical repair costs: £50–200 per tyre. Pre-MOT check: Check tread depth with a 20p coin — if the outer band is visible, the tyre is too worn. Look for bulges, cuts, or embedded objects. Ensure all tyres match the recommended size and load rating.
Lamps, reflectors and electrical equipment — 22.3% of failures
Lamps, reflectors and electrical equipment issues account for 22.3% of MOT failures on the Citroen C4. Lighting failures cover all external lights: headlights, tail lights, brake lights, indicators, fog lights, and reflectors. A single blown bulb will cause an MOT fail. This is one of the most preventable failure categories. Typical repair costs: £5–50. Pre-MOT check: Walk around the car and check every light — headlights (dipped and main beam), side lights, tail lights, brake lights, indicators, hazard lights, reverse light, rear fog light, and number plate lights. Replace any blown bulbs before the test.
