A lawsuit accuses Hyundai of falsely increasing its electric vehicle sales figures to satisfy its South Korean investors.
The lawsuit claims that a Hyundai manager pressured dealers to report unsold electric vehicles as sold, promising extra inventory in return.
Hyundai has reported impressive EV sales in recent months, despite a general decline in demand for electric cars.
Hyundai has denied the allegations, stating that it is investigating the matter and does not tolerate fraudulent sales practices.
