Quick summary
Total: 7,687 cars
The 2021 Citroën Relay shows a significantly higher overall defect rate of 141 defects per 100 vehicles, compared to the average of 79 defects per 100 for cars of the same year. This model particularly struggles with braking, steering, and visibility issues, with defect rates well above the average for these categories. Additionally, it has alarming rates in lights and electrics, body and structure, and equipment defects, all of which exceed typical averages considerably. Interestingly, the defect rate increases with mileage, suggesting that older models face more issues as they age, particularly in the 124,000+ miles category. Overall, while tyre wear is a concern, the Relay's specific deficiencies in multiple crucial areas are more notable.
