Quick summary
Total: 333 cars
The 2011 Mazda Bongo has an overall defect rate of 421 defects per 100 vehicles, significantly higher than the yearly average of 271 defects per 100 vehicles, indicating a 56% increase compared to similar models. This trend is particularly pronounced in the lowest mileage category, where it shows a defect rate of 1700 defects per 100 vehicles, far exceeding the average. The Bongo also demonstrates notable weaknesses in categories such as Steering, Visibility, and Lights & Electrics, with defect rates well above the average, suggesting these areas may require extra attention. Conversely, while it has some higher defect rates, it stands out in the Body/Structure category, where its rate is significantly higher than average, indicating potential structural issues in this model. Overall, the Mazda Bongo's defect profile suggests it is less reliable than its contemporaries, particularly for vehicles with low mileage.
