Quick summary
Total: 190 cars
The 2023 Audi A3 shows a slightly lower overall defect rate compared to the average car of the same year, with 35 defects per 100 vehicles versus the average of 36. While tyre wear is common across vehicles, the A3 stands out positively in several categories, notably brakes, lights and electrics, as well as body structure, where it had no recorded defects. However, it does face challenges with steering, visibility, and wheels, suspensions, and axles, having higher rates of defects in these areas compared to the average. The data reveals that as mileage increases, the defect rate generally rises, particularly beyond 31,000 miles, indicating potential issues with older vehicles.
