What has happened?

Kia, the sister brand to Hyundai, has been implicated in emissions cheating. In 2014, Kia was fined $100 million by the United States Environmental Protection Agency (EPA) for violations of the Clean Air Act (US). According to the Transport & Environment (T&E), a clean transport campaign group, the test results of the Kia Sportage III 1.7 and 2.0 litre models have indicated the presence of thermal windows and test recognition technology. T&E estimate that as many as 704,000 dirty Kia diesels have been sold in Europe as of 2016.

Can I join?

Independent research particularly implicates the Sportage III as containing potentially illegal defeat devices.

However, anybody who bought a Euro 5 or Euro 6 diesel Kia in England or Wales can apply to join the claim. If you bought or leased an affected Kia in Scotland or Northern Ireland, you can still complete our questionnaire, but your claim will be handled slightly differently.

The litigation will be free at the point of use. Harcus Parker will act on a no-win, no-fee basis, and will pay any third-party costs which are necessary in order to progress the claims to trial.


NOx contains both Nitrogen Oxide and Nitrogen Dioxide. NOx is emitted when fossil fuels are burnt, but not completely combusted. Diesel engines are not 100% efficient, meaning that their exhaust emissions contain NOx, as well as greenhouse gases such as carbon dioxide and carbon monoxide, and air pollutants such as particulate matter. NOx worsens air quality and has adverse health effects including contributing to respiratory problems and cancer. Diesel cars are one of the main causes of pollution in our air.

These allow cars to turn down their emissions control system outside the emissions testing environment i.e. when the cars are driven in the real world. Not all defeat devices are cheating devices – some are allowed by regulations. However, in many cases they are used by manufacturers to give the appearance that their diesel vehicles pass emissions tests, when in fact they do not.

The term used to describe the emissions scandal which broke when the German car maker, VW, admitted to fitting more than 11 million of their VW cars with unlawful defeat devices leading to the first major emissions class action lawsuit in the United States.

We use this term to cover both owners of cars, and people who leased their cars.

A senior court of England and Wales dealing with high value and high importance non-criminal matters. This court ruled that it will be bound by findings of the KBA (the German motor authority) that defeat devices are present.
