The 2015 Hyundai i40 has an overall defect rate of 168 per 100 vehicles, which is slightly lower than the yearly average of 170 per 100 vehicles.

The model excels in visibility, body structure, and equipment defects, all of which are significantly lower than the average rates. Conversely, it performs worse in brakes and steering, with defect rates substantially higher than those of the average car. Overall, while the i40 is generally reliable, attention should be given to its braking and steering systems as mileage increases.
