During the three-year warranty period offered by most manufacturers there are an average of claims per car against guarantees. During seven years, Kia customers make an average claims. That's of a claim per car in the final four years of the warranty. This means the Kia cars get checked and repaired more and get more reliable in the long run. This seems to have a positive effect on the used value of Kia cars on the second hand market. The customer therefore wins twice: he gets 7 years of peace of mind, and a higher resale price. Kia from its side, almost tripled its market share.
