On February 8, the State Administration for Market Regulation issued a notice stating that Mercedes-Benz (China) Automobile Sales Co., Ltd. is recalling 13 imported S-Class vehicles manufactured between May 3, 2017, and May 2, 2018. The rationale behind this recall is that during routine after-sales maintenance, the software of the engine control unit and transmission control unit in these vehicles was inadvertently upgraded to an incorrect version. Consequently, the vehicles fail to adhere to motor vehicle emission standards and on-board diagnostic system requirements, posing a potential emission hazard. Additionally, Beijing Benz Automotive Co., Ltd. has announced the recall of 17,235 domestically produced E-Class vehicles manufactured between July 11, 2024, and October 14, 2024. These vehicles are affected by an improperly configured software version of the transmission control unit, which results in inaccurate torque and power readings displayed on the instrument cluster. Similar to the imported S-Class vehicles, they may also not meet the required motor vehicle emission standards and on-board diagnostic system specifications, thus presenting an emission risk.
