Following an investigation and audit brought on by a number of consumer complaints, the U.S. Environmental Protection Agency (EPA) has changed the estimated fuel economy ratings for the majority of 2012 and 2013 models offered by Hyundai Motor America and Kia Motors America. The two companies will re-label cars that are currently on dealer lots with stickers reflecting the correct mileage ratings.
Most labels will show a decrease of one to two miles per gallon, and the biggest change will be made to the rating on the Kia Soul, which will be reduced by six miles per gallon.
According to the EPA, the agency routinely tests 150 to 200 vehicles a year “to ensure that their performance matches the mileage and emissions data” that automakers must submit to the EPA as well as put on stickers on new cars. This is only the second time since 2000 that the EPA tests have discovered label values that were incorrect.
A list of the Hyundai and Kia models affected by the change and the correct fuel economy ratings are available here.
