The 2011 Renault Master presents a higher overall defect rate, with 366 defects per 100 vehicles, compared to the average of 271 defects per 100 vehicles, indicating 35% more issues than typical for its year. Notably, it shows significant challenges in the brake category, where it has a defect rate of 231 compared to the average of 112. Additionally, this model underperforms in visibility and lights & electrics, with defect rates substantially above the average figures. In contrast, it does have relatively lower concerns in other areas, such as body/structure and equipment, reinforcing that while some defects are more prominent, others are less common compared to the yearly average. Mileage trends suggest that defect rates increase with age, particularly noted in the highest mileage bracket, which may require closer examination for long-term reliability.
