The Advertising Standards Authority (ASA) has ruled against Kia Motors’ seven-year warranty advert after a complaint by Warranty Direct.

The ASA found Kia Motors breached its code by not giving enough prominence to the 100,000-mile limit on its seven-year warranty and that the advertisements were misleading because they did not highlight the varying periods of cover for different parts.

“We concluded the mileage limit was not displayed with sufficient clarity and prominence,” said the ASA.

Kia said it had made an effort not to exaggerate the claims for the warranty and has now amended the adverts.
