Quick summary
Total: 114 cars
The 2002 Audi A8 shows a significantly lower overall defect rate of 230 per 100 vehicles compared to the yearly average of 374 per 100, which is 39% better than the average for its age. The model performs particularly well in categories such as brakes, steering, and lights and electrics, with defects in these areas being markedly lower than the average. However, it has a higher incidence of defects in the "Other" category, indicating it may encounter issues not commonly found in the average vehicle. There are also concerning trends in the higher mileage segments, especially between 93,000 to 124,000 miles, which suggests potential reliability issues as vehicles age.
