Quick summary
Total: 242 cars
The 2020 MG 5 has an overall defect rate of 93 per 100 vehicles, slightly above the average rate of 90 per 100, indicating a relative increase of 3%. Notably, this model performs exceptionally well in categories such as brakes, steering, visibility, body structure, and equipment, with significantly lower defect rates compared to the average car. However, it shows a concerning trend in the wheels, suspensions, and axles category, where defect rates are notably higher at 138 per 100. Mileage-related trends indicate that defect rates tend to rise with increased mileage for both this model and the average, but the MG 5 exhibits higher rates across the board. Overall, while the MG 5 excels in certain areas, it faces challenges with specific components that should be monitored.
