Tesla is facing a complaint in South Korea alleging it misled customers by marketing its “Full Self-Driving (Supervised)” software to buyers whose vehicles may not be legally able to use it. NDTV reports Tesla has long marketed the software in South Korea and collected lump-sum payments, citing a figure of 9.043 million won.

Multiple outlets, citing Reuters, say the complaint is planned by the consumer advocacy group Citizens United for Consumer Sovereignty and will be filed with South Korea’s Korea Fair Trade Commission (KFTC). The group argues that, based on Tesla’s own numbers, almost all Teslas sold in Korea last year would fall into the category of cars that cannot legally run the system. Coverage also notes a recent development in the courts involving a refund lawsuit brought by Korean owners.

Some reports add further context about how vehicle origin and regulatory recognition of safety standards affect eligibility, and they describe an alleged delay in pursuing certification for vehicles made in China. Other coverage focuses more narrowly on the complaint’s core allegation and the regulator to which it is directed.
