Quick summary
Total: 20,039 cars
The 2017 Citroen C3 has an overall defect rate of 163 per 100 vehicles, which is 22% higher than the average of 134 defects per 100 cars of the same year. This model shows a concerning trend in higher defects as mileage increases, particularly in categories such as Lights & Electrics and Body/Structure, where it exceeds average rates significantly. However, it performs better than average in Steering, Visibility, and Equipment, with notably lower defect rates in these areas. Overall, while it has some strengths, the C3's higher overall defect rate suggests it may require more attention than its peers.
