Quick summary
Total: 4,882 cars
The 2021 Renault Master has a notably higher defect rate than the average car of the same year, with 130 defects per 100 vehicles compared to 79 on average, indicating a performance that is 65% worse than the average. The defect rate increases with mileage, particularly in the higher mileage categories, which suggests increased wear and tear over time. Specific areas where the Renault Master stands out negatively include brakes and lights & electrics, where defect rates are significantly higher than average, at 70% and 63% respectively. However, it shows a concerning trend across visibility and body/structure defects as well, both of which are markedly above average.
