Some 40,000 units of the Hyundai Tucson and Kia Sportage, which have been found to have faulty emissions parts, will be recalled.
The Ministry of Environment said it will conduct voluntary emission component defect correction on Hyundai Motor Co.'s Tucson 2.0 diesel cars and Kia Motors Sportage 2.0 diesel cars starting Sept. 25.
Subject to the recall are 21,720 units of Hyundai's Tucson 2.0 diesel vehicles and 19,785 units of Kia's Sportage 2.0 diesel vehicles, which are applied by the latest emission standards of the Euro6.
Components subject to recall are diesel particulate filter (DPF) that are removing particle materials from emissions and electronic control system software that controls the operating conditions of these components.
It has been revealed that these vehicles have failed to do their own function as the emission temperature control software of electronic control devices does not fully reflect the material characteristics of the smoke-reducing devices.
The authorities say that if the vehicle is stopped during the process of periodically burning and removing smoke accumulated in the smoke reduction device, the temperature of the filter may exceed 1,150°C, causing the warning lamp of the exhaust gas self-diagnostic device.
The makers recently submitted a defect correction plan to the Environment Ministry to improve electronic control device software and replace damaged smoke-reducing devices free of charge.
