Quick summary
Total: 1,165 cars
The 2018 Hyundai I800 has an overall defect rate of 171 per 100 vehicles, which is significantly higher than the average of 120 per 100 for cars of the same year, representing a 42.5% increase. Notably, the defect rate rises with mileage, particularly in higher mileage categories. While the I800 excels in steering and body/structure issues, showing markedly fewer defects compared to the average, it struggles with brakes, visibility, lights and electrics, and overall equipment defects, all of which are much more common in this model than in similar vehicles. This indicates that while the I800 has strengths, it also has areas that may require more attention during maintenance.
