The 2014 Mazda 3 has an overall defect rate of 199 per 100 vehicles, slightly higher than the average for cars of the same year at 194 per 100. A notable concern for this model is the brakes, which show a significantly higher defect rate compared to the average, with 147 defects per 100 vehicles against 93 for others. However, the Mazda 3 excels in several areas, particularly in steering, lights and electrics, body structure, equipment, and other categories, all showing significantly lower defect rates than the averages. Mileage trends indicate that defect rates increase with mileage, especially in the higher mileage brackets for this model, which may warrant attention for long-term owners.
