The 1997 Mazda Bongo has an overall defect rate of 429 per 100 vehicles, which is 28% higher than the average rate of 335 per 100 for cars of the same year. Notably, the Bongo shows a significant increase in defects with mileage, particularly above 124,000 miles, where the defect rate rises to 567 per 100. While the model performs better in the equipment category, it stands out negatively in lights and electrics, wheels, suspensions, axles, and body structure, all of which have higher defect rates compared to the yearly averages. This indicates that the Bongo may have specific vulnerabilities as it ages, particularly in these key areas.
