The Korean transport ministry said Tuesday that it has filed a complaint against Mercedes-Benz Korea for selling cars with wrong specifications.

The local unit of the German car brand sold 98 units of the S350d series sedan with a nine-speed automatic transmission since Jan, 27, 2016, but the vehicles were labeled as having a seven-speed transmission, according to the Ministry of Land, Infrastructure and Transport.

The company sold upgraded models of S350d sedans in January but missed reporting the change in the technical data of the vehicle.

According to Korean vehicle management law, all car manufacturers and importers must report the exact specifications of the vehicle to the transport ministry. Otherwise, they will be subject to up to 10 million won in fines.

The ministry said the Mercedes-Benz vehicles also did not go through air emission and fuel assessment tests, violating Korean environment and energy management laws.

The ministry suspended sales of the models on Feb. 29 and filed a complaint with state prosecution for violating the related laws on Tuesday. (Yonhap)
