Quick summary
Total: 172 cars
The 1993 Toyota Corolla has an overall defect rate of 298 per 100 vehicles, which is slightly below the yearly average of 300 per 100. Notably, it shows higher defect rates in the 'Wheels, Suspensions & Axles' and 'Equipment' categories, performing worse than the average in both areas. In contrast, the Corolla excels in 'Steering', 'Visibility', and 'Body/Structure', with significantly lower defect rates compared to the average. Mileage trends indicate that the defect rate increases with higher mileage, particularly in the 93,000–124,000 miles segment. Overall, while there are some areas of concern, the Corolla demonstrates strength in several key aspects.
