Citroen C4: every year fails more than average

Based on 139,017 real MOT tests from DVSA records. Each year is compared against every other car first registered the same year — otherwise the numbers would only tell you that older cars fail more, which you knew.

The short answer

Avoid 2007 to 2016 and 2018 to 2019. The worst is the 2014, which fails its MOT 41% more often than other cars of the same age.

Found a Citroen C4 you like?

Averages tell you what to expect. Its registration tells you what actually happened — every MOT, every advisory, and whether the mileage adds up.

How this is worked out

Every MOT test recorded by DVSA in 2023 on a Citroen C4, grouped by the year the car was first registered. Retests are excluded, so a car that failed and was fixed still counts as a failure. Each year's rate is then divided by the rate for all cars first registered that year — so 120 means 20% more failures than its contemporaries, not 20% more than a brand new car.
