Quick summary
Total: 23,686 cars
The 2019 Audi A3 has an overall defect rate of 88 defects per 100 vehicles, which is significantly lower than the average for its year, standing at 106 defects per 100 vehicles, representing a 17.4% improvement. Notably, the model performs better than average in several categories, including brakes, steering, and body structure, with defects in these areas being considerably lower than typical figures. However, higher defect rates are observed in the early mileage segments, particularly between 0–31,000 and 31,000–62,000 miles, suggesting that newer models might experience more issues at the start of their lifespan. In summary, the Audi A3 stands out positively for its reliability compared to other vehicles of the same year, especially in critical safety aspects.
