Quick summary
Total: 5,141 cars
The 2007 Mazda 3 shows a higher overall defect rate of 421 per 100 vehicles compared to the average of 352 per 100, which is a significant 19.5% increase. Mileage-related trends indicate that defect rates rise steadily with increased mileage, particularly in the highest mileage bracket, which exceeds the average figures. Although the Mazda 3 performs notably better in brakes and steering, it struggles with higher defects in categories such as lights and electrics, wheels and suspensions, and body structure, where rates are considerably above average. Overall, while it demonstrates strengths in certain areas, it presents more challenges in other critical aspects compared to similar vehicles from the same year.
