BYD Company Limited—South Korean lawmakers grilled BYD over unverified claims on China data transfer and remote-access capability; regulator confirmed zero real-world cybersecurity tests had been run
At the National Assembly's October 8, 2026 Land, Infrastructure and Transport Committee audit, lawmakers pressed BYD Korea CEO Jo In-cheol on whether Korean driving data is transferred to or usable by BYD's Chinese headquarters for autonomous-driving or AI development; Jo denied it, but the Korea Transportation Safety Authority confirmed it had conducted zero real-world cybersecurity assessments of BYD vehicles and committed to begin them. Lawmaker Eom Tae-young (People Power Party) noted BYD's claims remained unverified absent independent testing, and lawmakers separately questioned whether BYD's Chinese parent could issue remote commands to Korean vehicles -- a concern tied to China's National Intelligence Law and Data Security Law, which compel firms to assist state intelligence work. BYD Korea's head did not directly answer the remote-access question, saying he understood no such authority existed. Tesla Korea was questioned on similar data-access issues at the same hearing.
