Quick summary

Total: 1,921 cars

The 2021 Hyundai I30 shows a slightly higher overall defect rate compared to the average car of the same year, with 79 defects per 100 vehicles against the average of 79. The model particularly excels in areas like steering, lights and electrics, and equipment, demonstrating significantly fewer issues than typical. However, it struggles with visibility, body structure, and other categories, where it reports higher defect rates. Additionally, as mileage increases, the rate of defects also rises notably, especially in the highest mileage category, suggesting increased wear and tear over time. Overall, while the I30 performs well in some areas, it has specific weaknesses that potential buyers should consider.
